Frictional Loss of Prestress Caused by Locally Deflected Tendons and Effectiveness of
Block-out in Prestressed Concrete Girder Bridges
Kyung-Joon Shin, Yun Yong Kim and Hwan-Woo Lee
Chungnam National University, Daejeon, KOREA
Abstract. Prestressed concrete girder bridge are one of the most widely used bridges in the world
because of their excellent construction feasibility, economic efficiency, serviceability, and safety. In
certain situations, however, the prestressing tendon is supposed to be bent locally, and this leads to the
loss of prestress force. This kind of prestress loss is not considered in the design and construction
processes. This study shows that prestress loss occurs at the locally bent tendon, and that a 2%
maximum of prestress loss occurs at the locally bent tendon, due to eccentricity.

Evaluation of Two Different Energy Inputs for Deposition of Stellite 6 by Laser Cladding
on a Martensitic Stainless Steel Substrate
Alain Kusmoko and Huijun Li
University of Wollongong, NSW 2522, Australia
Abstract. Stellite 6 was deposited by laser cladding on a martensitic stainless steel substrate with
energy inputs of 1 kW (MSS-1) and 1.8 kW (MSS-1.8). The chemical compositions and
microstructures of these coatings were characterized by atomic absorption spectroscopy, optical
microscopy and scanning electron microscopy. The microhardness of the coatings was measured and
the wear mechanism of the coatings was assessed using a pin-on-plate (reciprocating) wear testing
machine. The results showed less cracking and pore development for Stellite 6 coatings applied to the
MSS steel substrate with the lower heat input (MSS-1). Further, the Stellite coating for MSS-1 was
significantly harder than that obtained for MSS-1.8. The wear test results indicated that the weight loss
for MSS-1 was much lower than for MSS-1.8. It is concluded that the lower hardness of the coating for
MSS-1.8, markedly reduced the wear resistance of the Stellite 6 coating.

Patterning of Polymer Arrays with Enhanced Aspect-Ratio Using a Novel Substrate
Conformal Imprint Lithography
Vijay Ramya Kolli, Carsten Woidt, Hartmut Hillmer
University of Kassel, Heinrich-plett-Str.40, kassel, Germany
Abstract. Ultraviolet Substrate Conformal Imprint Lithography (SCIL) is an economic nano
lithography technique of imprinting high-fidelity patterns over large areas. It is an improvement to
conventional UV-Nanoimprint lithography (NIL) with high resolution, flexibility and conformal
imprinting. However the aspect-ratio of SCIL is limited due to its patterning by capillary forces and the
PDMS material has very low Young’s modulus (<2Mpa) hence, resulting in deformation of the feature
sizes during the imprint process. In general the residual layer between the imprinted structures is etched
9/ 41
2015 IACSIT SINGAPORE CONFERENCES
away to obtain high aspect ratio. But in industrial applications an array of different 3D patterns are
imprinted in a single step, thus, the residual layer of each structure depends on its volume and viscosity
of the imprint material, thereby making the etching process impossible to increase the feature size and
aspect-ratio of each microstructure individually. Hence in this paper a new SCIL stamp technique is
demonstrated to implement an enhancement of aspect ratio. In this process, a flexible polymer material,
Polydimethylsiloxane (PDMS) is used as the stamp material. The heights of the structure on the stamp
are supported by a metal layer (higher Young’s modulus), which provides higher stiffness and rigidity
to the stamp and thereby avoiding distortion of the patterns on the stamp. Also the metal layer acts as an
UV blocking mask: hence while patterning on an UV curable imprint material, the residual edges of the
microstructures, which are subjected to decrease the feature size, are removed in the development
process of the uncured polymer areas. Thus, irrespective of the number and shape of the
microstructures, an enhancement of aspect ratio is attained in a single step. Conventional imprinting of
circular polymer arrays with dimensions 90µm / 70nm on their master template resulted in increased
feature size up to 150 µm, while the height varied between 90-66nm and thereby decreasing the aspect
ratio. Imprinting with the proposed SCIL technique resulted in 96 µm / 74nm dimension, thus around
60 µm of feature size improvement is achieved

Hybrid hetero p-n Junction Between ZnO Microspheres and p-type Materials
Tatsuya Ikebuchi, Norihiro Tetsuyama, Mitsuhiro Higashihata, Hiroshi Ikenoue,
Daisuke Nakamura, and Tatsuo Okada
Kyushu University, Japan
Abstract. We report a hybrid hetero p-n junction between Zinc Oxide (ZnO) microspheres and p-GaN
thin film or poly (3, 4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS). ZnO
microspheres, which have high crystalline quality, were synthesized by ablating a ZnO sintered target
with focused pulsed laser at high fluence. Recent investigation has demonstrated that ZnO microspheres
had high optical property and laser actions in the WGM (whispering gallery mode) from the
microshperes under pulsed laser irradiation. In this study, we fabricated a hybrid hetero p-n junction
between ZnO microspheres and p-GaN or PEDOT: PSS, and both p-n junctions with p-GaN or
PEDOT: PSS had a good rectifying characteristic. In the case of p-GaN, electroluminescence was
observed under forward bias.

Processing of High Strength Magnesium Alloy with Enhanced Plasticity using Squeeze
Casting
Khin Sandar Tun, Goh Chwee Sim, Tan Xinghe, Chan Kwok Weng Jimmy, Kwok Wai
Onn Richard, Lee Teck Kheng, Manoj Gupta
Institute of Technical Education, 2 Ang Mo Kio Drive, Singapore
Abstract. Crystalline Mg-Cu-Y alloy system was fabricated using the squeeze casting technique.
Microstructure showed the multiphase structure composed of primary Mg rich phase distributed among
the lamellae patterns, alternative layers of LPSO Mg phase and intermetallic phases. High
microhardness and tensile strength of 104 HV and 223 MPa respectively were observed in the squeeze
cast alloy. A good combination of compressive strength (706 MPa) and ductility (19%) was also
achieved in the crystalline alloy which is unlikely to be attainable in amorphous Mg-Cu-Y system. The
formation of LPSO phase in the current Mg-Cu-Y alloy mainly contributed to the high mechanical
properties.

On the Formation of Nanograined LiCo2O3(OH) Spinel-Type Material Synthesized via
Modified Low-Temperature Sol-Gel Approach
Rinlee Butch M. Cervera, Shu Yamaguchi
University of the Philippines, Diliman, Metro Manila, Philippines
Abstract. A new lithium cobalt oxyhydroxide compound has been successfully synthesized. This new
compound has been found to be related to the low temperature LiCoO2 (LT-LiCoO2) spinel structure
formed at low processing temperatures. With the use of a modified sol-gel approach, this compound
with the composition of LiCo2O3(OH) can be successfully synthesized at around 150 oC. Structural
analyses using powder X-ray diffraction (XRD) and selected area electron diffraction (SAED) suggest a
cubic-spinel structure, which is also supported by FT-IR and TG/DTA analyses. In addition, from the
TEM morphological analysis, a very fine nanograined LiCo2O3(OH) powder with an average grain size
10/ 41
2015 IACSIT SINGAPORE CONFERENCES
of 5 nm has been obtained. From these results, the presence of OH or water at low processing
temperatures promotes a favorable formation of this structure. At higher temperatures (>400 oC), the
phase transforms to a layered high-temperature LiCoO2 (HT-LiCoO2) structure with the excess cobalt
precipitated as Co3O4 as suggested by the in-situ high temperature XRD analysis.

Preparation and Characterization of sPDVB/SPPO Composite Proton Exchange Membrane
for Fuel Cell
Gongwen Zou, Xu Liu, Chuanbo Cong, Qiong Zhou, Kun Zhao
China University of Petroleum, China
Abstract. In this study, a series of composite proton exchange membranes are prepared from sulfonated
polydivinyl benzene (sPDVB) microspheres and sulfonated polyphenyl ether (SPPO). The PDVB
microsphers and PPO are functionalized by direct sulfonation. The synthesis products are characterized
by Fourier Transform Infrared Spectroscopy technique (FT-IR), thermogravimetry analysis (TGA),
scanning electron microscope (SEM). The incorporation of sPDVB decreases the water uptake and
proton exchange capacity, so the proton conductivity is lower than that of blank SPPO membrane. But
the composite membranes still have the excellent conductivity range from 4.88×10-2 to 6.99×10-2
Scm-1.

Laser surface melting of Ti6Al4V alloy with Ti-BN-C mixed powders
Xian Zeng, Tomiko Yamaguchi, Kazumasa Nishio
Kyushu Institute of Technology, Kitakyushu 804-8550, Japan
Abstract. Laser surface melting was carried out on the surface of Ti-6Al-4V alloy with Ti-BN-C mixed
powders. In this paper, an influence of the mole ratio of BN/ C on microstructure, chemical
composition, element distribution and hardness were separately analyzed by scanning electron
microscope (SEM), X-ray diffraction (XRD), electron probe micro-analyzer (EPMA) and Vickers
hardness test (HV). The results showed that the melting layer mainly consisted of TiCxN1-x (x=0, 0.3,
0.7), TiB and Ti. The hardness was increased with improving the mole ratio of BN/C ratio.

Modification of the mechanical behavior in the glass transition region of poly(lactic acid)
(PLA) through catalyzed reactive extrusion with poly(carbonate) (PC)
Vu Thanh Phuong, Maria-Beatrice Coltelli, Irene Angullesi, Patrizia Cinelli and
Andrea Lazzeri
Can Tho University, Viet Nam
Abstract. In order to improve the thermal stability of PLA based materials it was followed the strategy
of blending it with a polymer having a higher glass transition temperature such as poly(carbonate) of
bisphenol A (PC) . PLA/PC blends with different compositions were by melt extrusion produced also in
the presence of an interchange reaction catalyst, tetrabutylammonium tetraphenylborate (TBATPB) and
triacetin. The dynamical mechanical thermal characterization showed an interesting change of the
storage modulus behavior in the PLA glass transition region, evident exclusively in the catalyzed
blends. In particular, a new peak in the Tan δ trend at a temperature in between the one of PLA and the
one of PC was observed only in the blends obtained in the presence of triacetin and TBATPB. The
height and maximum temperature of the peak was different after the annealing of samples at 80°C. The
data showed an interesting improvement of thermal stability above the PLA glass transition, this was
explained keeping into account the formation of PLA-PC copolymer during the reactive extrusion.
Furthermore, the glass transition temperature of the copolymer as a function of composition was studied
and the obtained trend was discussed by comparing with literature models developed for copolymers.

Abstract: Multi-modal microscopy is a term that refers to combining different
imaging and mapping modes applied to the same object in order to obtain
complementary information about material structure, function and properties.
Alongside the well-established modalities, such as optical microscopy (including
using polarized light) and scanning electro microscopy (including EDX and EBSD),
multi-modal microscopy includes the use of TEM and STEM, AFM, as well as
focused beams of ions (FIB), neutrons and X-rays. The advent of tight focusing of
X-rays down to sub-micron has opened up a vast range of possibilities in terms of
full field imaging (including tomography), as well as scanning transmission X-ray
microscopies (STXM) that can be used in the WAXS or SAXS regimes, as well as
spectroscopic analysis (XAS).
In the lecture examples will be shown and explained of the application of this
approach in our labs: the Multi-Beam Laboratory for Engineering Microscopy
(MBLEM) at Oxford, and the Centre for In situ Processing Studies (CIPS) at the
Research Centre at Harwell (UK). The materials studied cover a wide range, from
human dental tissues to engineering ceramics and polymers, as well as structural
metallic alloys
Topic: Stability of Biopolymer Nanocomposites
Prof. Maria Mucha
Technical University of Łódź, Poland
Abstract: Biopolymer nanocomposites are not only the green and biodegradable,
but also high performance material which exhibit unusual property combinations
and unique design possibilities. With an estimated annual growth rate of about
25% and fastest demand to be in engineering plastics, their potential is so striking
that they are useful in several areas ranging from packaging to biomedical
applications. Hybrid organic/inorganic nanocomposites, reported to be the
materials of 21st century are being developed to improve the physical and
mechanical properties of polymeric materials without adversely effecting their
processing characteristics.
The number of published papers containing words such as nanoscience,
12/ 41
2015 IACSIT SINGAPORE CONFERENCES
nanotechnology, nanomaterials is still growing. Additionally, specific conferences
and special journals have been dedicated exclusively to the evolving science and
technology of nanomaterials.
Our studies are focused on stability of biopolymer nanocomposites and their
degradation precess. Degradation of polymers is very complex and numerous
factors influence this process: temperature, light, atmosphere, humidity, presence
of internal and external impurities, thermal or photochemical catalysts or
sensitizers. Even if the properties and environmental stability of virgin biopolymers
are well known, the general understanding of biopolymer properties with
nanoadditives is still not to be reached. The mutual interactions between
degradation products formed in each components can significantly change the
course of decomposition in the blend or composite.
The aim of our work was to study the photochemical and thermal degradation of
two widely used biopolymers in composites with various nanoadditives (Ag, TiO2,
CuO and organo-modified montmorillonite): Poly(lactic acid) (PLA)biodegradable thermoplastic aliphatic polyester and chitosan (CS)- a linear
polysaccharide produced by the deacetylation of chitin, a naturally occurring
polymer. The changes of physicochemical properties of nanocomposites have been
studied by FTIR spectroscopy, DSC analysis and mechanical strength tests. The
results are very different. Nanosilver act as stabilizer for PLA photodegradation,
while in a case of thermal degradation opposite effect was observed. Nanoparticles
of copper oxide accelerate photodegradation of PLA. Studies of chitosan stability
shown, that TiO2 and silver nanoparticles improve its photostability (changes of
mechanical properties and number of chain scission). Organo-modified
montmorillonite is often added to polymers to enhance mechanical properties. Our
research confirms these results however the additive influences on the thermal
stability of chitosan.

Applying P-Diagram in Product Development Process: An Approach towards Design for
Six Sigma
Folasayo Olalere, Ab. Aziz Shuaib and Abu Hassan Hasbullah
Universiti Malaysia Kelantan
Abstract. Successful business enterprises are to a great extent determined by strong sales and overall
low operational cost; as a result, improving quality and reducing cost have been one of the important
tasks for any business enterprise. These will help in achieving high quality products at reasonable price.
Thus, due to the effectiveness of Six Sigma in improving quality and reducing cost, it has become an
excellent initiative that is gaining momentum in the business world. However, academics have
conducted little research regarding this phenomenon, especially on it applicability in manufacturing
industries. Therefore, this paper seeks the knowledge regarding how P-Diagram Model (Taguchi
Method) can be applied in product development stage to achieve Design for Six Sigma (DFSS). The
paper illuminates on “Process” as the basic unit for Six Sigma and how production process can be
enhanced using P-diagram. Following this understanding, the paper demonstrates how P-diagram can
be applied in conceptualizing and developing product ideas that put into consideration users intent
(User-centred design), reduce variations and thus, lower the risk of product failing.

Dual Sourcing and Capacity Allocation with Differentiated Product Demands
Hsing-Hua Lai, Chung-Chi Hsieh
National Cheng Kung University
Abstract. This paper examines a two-stage decentralized supply chain with one capacity-constrained
manufacturer sourcing from two competing suppliers with asymmetric component quality. The
manufacturer offers an established product which has a large and steady demand, and introduces a new
and differentiated (higher-quality) product which has a small and uncertain demand. In contrast to the
development maturity of the process for producing the established product, the process for producing
the high-quality product is still in production ramp-up phase and thus has a high production cost and
yield uncertainty. We analyze the manufacturer’s allocation decision for the processes and the
suppliers’ price decisions through a game-theoretical framework, and explore how the manufacturer can
benefit from the high-quality product. One crucial finding from our analysis is that the effects of certain
parameters, such as the expected yield and yield variation of producing high-quality products, on the
manufacturer profit are contingent on the expected demand of the high-quality production. This finding
enables the manufacturer to prioritize its profit-improving efforts when the expected demand of
high-quality products is very small and when it is not.

An Overbooking Model for Air Cargo Industry under Stochastic Booking Request and
Show-up Rate
Anupong Wannakrairot and Naragain Phumchusri
Chulalongkorn University
Abstract. Overbooking is a technique which sells goods or services in excess of the available capacity
because there is a possibility that some customers might not show up. In air cargo overbooking
14/ 41
2015 IACSIT SINGAPORE CONFERENCES
problem, overbooking model is more complex because of the two-dimensional characteristic. This
paper presents a two-dimensional air cargo overbooking model to find the optimal overbooking level in
order to minimize the total cost, which consists of spoilage and offloading costs. Booking requests and
show-up rate are random variables with known distributions. Sensitivity analysis is used to observe the
impact of the ratio between spoilage and offloading costs on the optimal overbooking level.

Effect of Trade Promotion in Centralized and Decentralized Supply Chain: Wholesale
Price Experiment
Phattarasaya Tantiwattanakul and Aussadavut Dumrongsiri
Sirindhorn International Institute of Technology, Thammasat University
Abstract. This research studies and compares behavior of centralized and decentralized supply chain. A
two level supply chain with a single manufacturer supplying a single product to a single retailer is
considered. The mathematical models were developed in centralized and decentralized to find the
minimum cost in multiple time periods. The effects of demand quantity, parameter, and wholesale price
on centralized and decentralized supply chain were explored. The numerical results show how the
parameters affect supply chain performance. Moreover, we analyze the effect of trade promotion on
decentralized supply chain. From the experiment, we can use trade promotion such as wholesale price
discount to reduce the supply chain cost.

Lean to Agile – A New Paradigm in Manufacturing
N. C. Dutta
Formerly Manager (Productivity Services & Value Engineering Division) Telco (Tata
Motors). INDIA: Consultant of State Productivity Council WB. INDIA.
Abstract. Today, business is nothing less than war and victory is transient; where success has become
an impermanent achievement which can be taken away by competitors any time. World-class
performance is a moving target that requires constant attention and effort; the process is a never ending
journey. In the past, economies of scale ruled the manufacturing world and everybody knew that mass
production and full utilization of plant capacity was the way to make money. This style of
manufacturing resulted in inflexible plants that could not be easily reconfigured, and were associated
with swollen raw materials, work-in-process and finished goods inventories.
Agile manufacturing systems are born as a solution to a society with an unpredictable and dynamic
demand, and with a high degree of mass customization in its products. It is the strategy that many
enterprises are adopting as a solution to the new market opportunities. Thus, it has rather become a
fundamental requisite for companies to continuously innovate and evolve according to the
ever-changing moods of the customers for their survival and growth. If they fail, unfortunately, there
will be no tomorrow for them.

Manufacturing in Flow Shop and Assembly Line Structure
Waldemar Gzrechca
Silesian University of Technology, Poland
Abstract. Product modularity has become an important issue. It allows producing different products
through combination of standard components. One of the characteristics of modular products is that
they share the same assembly structure for many assembly operations. The special structure of modular
products provides challenges and opportunities for operational design of assembly lines. In this paper,
an approach for design of assembly lines for modular products is proposed. This approach divides the
assembly line into two parts: a subassembly line for basic assembly operations and a production
structure for variant assembly operations. The design of the subassembly line for basic operations can
be viewed as a single product assembly line balancing problem and be solved by existing line balancing
methods. The subassembly line for the variant operations is designed as a flow shop structure and is
sequenced with Johnson’s algorithm for 2 machines case and heuristic methods for M machines case. A
final result of tasks assigning to the complex production structure is given and a quality of final
solutions is discussed.

2015 IACSIT SINGAPORE CONFERENCES
Abstract. This study aims at presenting a methodology for the taking decision about the retrofit or the
destruction of the damaged buildings by an earthquake. The proposition is founded on the damages
caused by the seism of Boumerdes in Algeria, on 23 May 2003. This work can to help the authorities
and owners to make a choice concerning the retrofit or the destruction of buildings and reconstruction.
The analysis begins by the identification of the structural damages in the structures, then by the
evaluation of costs of the reparations and the retrofit of all functions of the building. If the owner has
contracted insurance, the amount of insurance is deducted. After this step, this cost is compared to the
cost of the destroying of the old building and the rebuilding cost of a new similar building. The life
duration of structure is integrated respectively for the retrofitted building and the build of a new
equivalent building. The depreciation of capital according to the time of exploitation is calculated on
the reference: fifty years for the new investments, and twenty-five years for the retrofitted buildings.
The resolution of the problem uses the comparison between the cost of retrofit divided by twenty-five to
which added the amount of insurance, and the cost of new equivalent construction divided by fifty to
which added the amount of destruction. This approach gives a result according to retrofit, insurance, the
equivalent new building and the depreciation of capital. The compilation of the actualized costs
according to each zone permits to have a quick vision about the economical decision. The cost of the
urban land component is not taken in account and the network is considered in good state.

Abstract. Net Zero Energy Building (Net ZEB) concept has been applied to make a selected building
as a self-energy provider. The building was partly modified to reduce its energy consumption using
several energy efficient technologies such as wall material, insulator, VRF air condition unit, solar
lighting, LED light bulbs, etc. While, electricity served into the building was generated by solar energy
(PV panels). The monitored data over one year have proved that this build can generate the electricity
more than its energy demand. This is a good achievement of Net ZEB in Thailand.

A Clustering and Outlier Detection Scheme for Robust Parametric Model Estimation for
Plane Fitting
Rachna Verma and A. K. Verma
J.N.V. University, Jodhpur, India
Abstract. Extraction of geometric information and reconstruction of a parametric model from the data
points captured by various sensors or generated by various image preprocessing algorithms is a vital
research issue for many computer vision and robotics applications. The aim is to reconstruct 3D objects,
consisting of planar patches, in a scene from its point cloud captured by a sensor set. A reconstructed
scene has many applications such as stereo vision, robot navigation, medical imaging, etc. Unfortunately,
the captured point cloud often gets corrupted due to sensor errors/malfunctioning and preprocessing
algorithms. The corrupted data pose difficulty in accurate estimation of underlying geometric model
parameters. In this paper, a new algorithm has been proposed to efficiently and accurately estimate the
model parameters in heavily corrupted data points. The method is based on forming clusters of estimated
planes with reference to a fixed plane. Clustering is accomplished on the basis of angles and distances of
estimated planes from the reference plane. The proposed method is implemented over a wide range of data
points. It is a robust technique and observed to outperform the widely used RANSAC algorithm in terms
of accuracy and computational efficiency.

Modeling and Analysis of A Novel Flexible Capacitive-Based Tactile Sensor
Basma Gh. Elkilany and Elsayed A. Sallam
Tanta University, Egypt
Abstract. In recent years, autonomous robots have been increasingly deployed in unstructured and
unknown environments. In order to survive in theses environments, robots are equipped with sensors. One
of the main sensors is tactile sensor which provides the robots with tactile information like texture,
stiffness, temperature, vibration and normal and shear forces. In this paper, we propose a flexible
capacitive tactile sensor which is designed for measuring both normal and shear forces. The tactile sensing
unit consists of five layers, a bottom layer of Polyethylene Terephthalate (PET) with a pillar, two copper
electrodes embedded into a Polydimethylsiloxane (PDMS) film, a spacer, a Polyimide (PI) film and
finally a top PI bump. The bump and the pillar structure play a significant role in producing a torque for
shear force measurement. Finite element modeling (FEM) is conducted to analyze the deformation of the
sensing unit and simulated using COMSOL Multiphysics. The change of capacitance verse normal and
shear forces are obtained, a comparison between the proposed sensor and other pervious sensor is
conducted. The sensitivity of a cell is 0.22%/N within the full scale range of 10 N for normal force and
4%/N within the full scale range of 10 N for shear force.

2015 IACSIT SINGAPORE CONFERENCES
Abstract. It has been seen a rising trend in recent years for online shopping businesses across the UK.
Customers prefer to place their orders online to purchase goods and ordered goods are dispatched directly
from regional warehouses (or distribution centres) to customers’ door steps. A number of studies through
a literature review indicated that future generation warehouses may be designed and implemented as more
centralised distribution centres as this is the most cost-effective way to run businesses of this form for
many larger manufacturers, suppliers or retailers. These companies have therefore been seeking for even
more efficient and effective methods for storing, picking and dispatching goods in increasingly centralised
distribution centres in which a novel design of warehousing systems is desired. This paper presents a
framework of an RFID-based management system as part of a proposed future generation warehouse
design through application and integration of fast-growing IT technologies (radio frequency identification
(RFID) tags, wireless sensors and communication networks) to maximise the warehouse capacity and
achieve a better visualisation and real-time visibility of inventory control and data handling management.

The Impact Factor Study of The Lifecycle of Recyclable Spare Parts
Kuo Hsing Wu and Yang, Kang-Hung
Chung Yuan Christian University, Taiwan
Abstract. Aberdeen survey showed the top pressure that an organization face is increasing competition,
both in product and service [1]. Customer asks for high service level that is a must in product sales. This
paper defines a key indicator for the service level to recover and return defects within a short time.
However, according to Aberdeen survey, lacking of part availability makes defects not fixed in the first
visit 51% [2]. Therefore, the spare part availability acts a significant factor in customer satisfaction. High
spare part inventory certainly can improve the availability, but the accompanied cost is immense and
sometimes not affordable. Improving the efficiency of the spare part inventory plays a vital position.
There are two types of classifications for spare parts; the recyclable and consumable. Certain researches
have focused on consumable spare parts but few for recyclable. However, electronic appliances such as
smart phone and laptop computer rely on recyclable parts a lot because that dominates the service cost. In
this study, it probes the field of recyclable part to reveal results of the lifecycle and sort out the factors that
impact the efficiency in recyclable part inventory.

Abstract. A new design of CAM shaft has been investigated for Campro engine 3.0L V4 engine. The new
design adds a modification to Cam profile peak point in the Camshaft to be controllable at different
speeds through a hydraulic system. The new design was simulated in CFD for tolerating stresses. The new
design promotes Cams to give the exact heights at different engine speed depending on the optimize value
valve opening time. At the same time this paper discusses the prediction of power performance of internal
combustion engines with the new design. The expected result will significantly improve the engine
speed-torque curve, reduce emission gases, and reduce fuel consumption. The new design model
predictions need to be tested experimentally for further improvement in the hydraulic system before the
commercial use.

Dew Point Measurement Error Due to Tube Length in A Calibration Instrumentation and the
Evaluation of Measurement Uncertainty
Yun-Kyung Bae and Dong-Hoon, Hyun
Korea Testing Laboratory
Abstract. The purpose of this paper is to analyze the effect of tube length in calibration instrumentation
on dew point measurement of dew point sensors (DPS) and evaluation of measurement uncertainty. When
measuring dew point temperature, various tube lengths between dew point generator and dew point sensor
(DPS) cause a significant error due to moisture absorption of inner tube. The measurement is carried out
to analyze the variation on measured dew point temperature for four cases of tube lengths with 300 mm,
1200 mm, 2500 mm and 5000 mm. The dew point temperature measurements were performed in the
range from -60 ℃ to 10 ℃ by using calibrated standard chilled mirror hygrometer as reference standard.
In order to investigate contribution to the standard uncertainty for the tube length variation as an
uncertainty source, expanded uncertainties were evaluated for the cases including the effect of tube length
variation as an uncertainty source and excluding it at each measurement point. The measurement was
conducted according to standard calibration procedure of Korea Testing Laboratory which assures
suitability and traceable results. It is also based on international standards.

Blade Material
C Phaneendra Kiran and Shibu Clement
BITS-Pilani, Hyderabad campus , India
Abstract. The evaluation and selection of a turbine blade material involves several x-abilities and
attributes. A designer should consider lifecycle issues as well as design and manufacturing strategies
simultaneously at conceptual design stage without missing any of the information. In the proposed
methodology the comparison is made between different turbine blade materials based on different
x-abilities and attributes. The proposed methodology compares the materials using concurrent engineering
approach and multi attribute decision making approach (MADM). In the concurrent engineering approach
four x-abilities namely quality, manufacturing, environment and cost are considered. To maintain
uniformity attributes considered in MADM approach are same as concurrent engineering approach. Both
the methodologies show that ST12TE is the best material for turbine blade for the given set of attributes
and x-abilities.

Abstract. Smart phone market has been growing larger and larger in recent years. This fact makes
enormous competitiveness in its supply chain. Therefore, the product quality is the most importance part
to improve business competitiveness, especially a flexible printed circuit which is a main assembly
component in smart phones. This paper presents the approach to improve the quality control plan of the
flexible printed circuit backend process. Failure Mode Effective Analysis (FMEA) was adopted to
prioritize the defective and analyze weak points in the original quality control plan. Then, Statistical
Process Control (SPC), optimizing inspection method and working procedure of inspection process, were
introduced to improve the detection ability of the quality control plan. The results showed that the
implementation of the new quality control plan could reduce escaped defective parts and the expense of

An Investigation of Cone Angle During Roller Forming Process
Kagzi Shakil A. and Raval H. K.
Sardar Vallabhbhai National Institute of Technology (SVNIT), Surat, Gujarat, India
Abstract. Roller bending is the operation of bending long strip of metal by passing them between the sets
of rollers to obtain desired curvature. Due to the property of springback it is difficult to know the actual
position of the rollers to obtain the required curvature and cone angle. Therefore, in industries the trial and
error method is utilized to attain required curvature, which consumes a lot of time. In this regards, some
analytical models are available to predict the springback during three roller bending process. To have the
simplicity in evaluation certain assumptions are made such as constant radius during bending. In fact, the
radius continuously changes during the course of bending. An attempt is made to simulate the roller
bending process for conical bending process using FEA so as to eliminate the assumption of constant bend
radius. Various parameters such as plate thickness, bottom roller inclination and top roller inclination
affecting this cone angle are studied using FEA analysis.

Abstract. Flow forming process is a non linear plastic deformation process. It is mainly used in defense
and aerospace industries to manufacture missile casing, rocket and cartridge case, rocket motor cases, dish
antenna etc. In flow forming, a tube is placed over mandrel and rotating roller passed over it
circumference thus deformation of the tube takes place. During the process wall thickness reduces and
length of the tube increases. Surface finish, percentage elongation in length and reduction of area of the
finished components are mainly depending upon the configuration of the roller viz. attack (leading) angle,
smoothing (trailing) angle, nose radius, diameter and thickness of roller. Here an attempt is made to
analyze roller for different configuration using finite element tool. The roller has been designed using
PRO-E modeling tool and analysis has been carried out for different forces acting on roller using
ANSYS/Workbench. Von mises stress and maximum deformation of the rollers have been obtained and

Shaban, and Tsuyoshi Yoshitake
King Mongkut’s Institute of Technology Ladkrabang, Bangkok 10520, Thailand
Abstract. Preparation of n-type β-FeSi2/intrinsic Si/p-type Si heterojunctions was accomplished by
facing-target direct-current sputtering (FTDCS) and measuring their current-voltage characteristic curves
at low temperatures ranging from 300 K down to 50 K. A mechanism of carrier transport in the fabricated
heterojunctions was investigated based on thermionic emission theory. According to this theory, the
ideality factor was calculated from the slope of the linear part of the forward lnJ-V plot. The ideality
factor was 1.12 at 300 K and increased to 1.99 at 225 K. The estimated ideality factor implied that a
recombination process was the predominant mechanism of carrier transport. When the temperatures
decreased below 225 K, the ideality factor was estimated to be higher than two and parameter A was
estimated to be constant. The obtained results implied that the mechanism of carrier transport was
governed by a trap-assisted multi-step tunneling process. At high forward bias voltage, the predominant
mechanism of carrier transport was changed into a space charge limit current process.

Abstract. Metal foil strain gauges are most widely used for the stress analysis in engineering structures.
Typical strain gauge system includes strain sensitive grid, carrier material, and adhesive layer. Strain
measurement from the strain gauge is partially affected by carrier and adhesive materials and their
thickness. In the present work, a Finite Element Model is developed in order to study the effect of both
adhesive layer and carrier thickness on strain measurements while using strain gauges. To understand the
behavior of the adhesive material, mechanical characterization is done on bulk adhesive specimen. Finite
Element Analysis (FEA) is carried out with different materials namely epoxy and polyurethane. Initially a
single element foil loop is considered for the analysis and further this is extended to metal foil strain
gauge with nine end-loops. Finally, the strain variation through thickness of adhesive layer, carrier and
strain sensitive grid is obtained from FEA. The results thus obtained are compared with analytical results
from Basic Strength of Materials approach.

Abstract. Strain measurement from the strain gauge is partially affected by carrier and adhesive materials
and their thickness. Effect of adhesive layer thickness has been addressed in this paper. Well characterized
tensile experiments have been conducted using Al 6061-T6 specimens attached with strain gauges at mid
length of the specimen and strain gauges are attached with different materials namely epoxy and
polyurethane to understand the effect of adhesive layer thickness in strain measurement. The strain at a
location has been noted for one particular adhesive layer thickness value (0.13 mm) and similar
experiments have been carried out with different adhesive thickness values (0.16 mm, 0.18 mm and 0.26
mm). The results obtained from experiments have been compared with analytical results from Basic
Strength of Materials approach. Good agreement is seen between the experimental and analytical results.
It has been observed that the thickness of the adhesive layer plays significant role for getting accurate
strain.

Abstract. Evaluation and remaining life assessment of separator and demister for 55 MW geothermal
power generation plant have been conducted. The equipment has been used for 27 years and has stopped
operating due to the failure of steam turbine. Before it is operated back, the condition of separator and
demister needs to be evaluated and their remaining life assessment has to be calculated to anticipate the
future repair. The methods used for evaluation were UT phased array, thickness measurement, chemical
composition, hardness test and deposit composition analysis. The remaining life assessment was
calculated in correlation with thickness reduction. The results showed that the chemical composition and
hardness of materials met the standard of SA 516 Gr 70. No evidence of internal defect was found in
both equipment. The demister in all part is still in good condition and its remaining life was beyond 20
years. In separator, the reduction in thickness extremely occurred on top head and cone. The remaining
life of top head separator was below 1.2 years and cone separator was not more than 4.7 years. Deposit
analysis taken from demister gave evidence the presence of sulfur, silica, iron oxide, and sulfide iron.

Abstract. This paper presents an experimental investigation on the influences of EDM parameters on
machining time and surface roughness for machining Inconel 800.Inconel800is widely used in
construction of equipment that must have high strength and resist carburization, oxidation and other
harmful effects of high temperature exposure. The selected WEDM parameters are pulsed current
(210,220 and 230A), pulse-on time (2,3.25, 4.5, 5.75, 7 and 8.25µs) and pulse-off time (19 and 46µs).
It has been observed that surface roughness increases with the increase of pulse-on time and pulse
current. Similarly machining time decreases with the increase of pulse current and pulse-on time.
Conversely, a decreased value of pulsed current and pulse-on time results in a better surface finish and
increased machining time.

Abstract. Modern nanotechnology provides opportunities to produce nanoparticles. Employing
nanofluids meets the challenges due to unique transport properties. Also, it can be a combination of
different nanoparticles (structure, size) in different base-fluids with additives. The interactions

Abstract. The effects of Al, Co, Re, and Ru on the stacking fault energy in Ni alloys were analyzed
using computational thermodynamics. The effects of adding up to 5 at% Re or Ru to a Ni-15at%Co
system were found to be weak at 300 °C, 700 °C, and 900 °C. However, Al addition decreased the
stacking fault energy in a Ni-15at%Co-Xat%Ru system, where X = 0, 3, 5. In addition, this decrease
in the stacking fault energy due to Al addition became more significant as the amount of Ru
increased. Furthermore, in Ni–Co–Al–Ru alloys containing 9at%Al, the addition of 5at%Ru
decreased the stacking fault energy as much as the addition of 12.5at%Co at 900 °C. The effects of Co

Abstract. Silicon-based anode is one of the most promising anode materials for next generation
batteries due to its high theoretical capacity of about 4200 mAh/g. However, the hurdle of using such
high capacity anode material is its large volumetric change during lithiation and delithiation causing
capacity fading. In this study, in order to circumvent the large volumetric change, nanograined size
SiO2 incorporated with Fe having compositions of FexSi1-xO2 (x=0.05, 0.10) have been synthesized
using a modified sol-gel processing and fully characterized for its structure, morphology, and thermal
properties. From the different characterization results, the samples synthesized at low processing
temperatures (400 and 600 oC) suggest an amorphous structure with grain size of about 5 nm and Fe
successfully incorporated into the amorphous nanograined SiO2 matrix.

specimens have the cross-sectional dimension of 102×29×6 mm with span-to-depth ratios, ranging
from 20 to 40. A total of 40 mono-symmetric section tests were performed. The effects of vertical
load position through the cross-section were studied. Also, shear center position with concentric load
and three different eccentricities were investigated ranging from 0 to -3e. The specimens were tested
to final buckling. Based upon the results of this study, it is found that the load versus mid-span
vertical deflection relationships of the beams are linear up to the failure. On the contrary, the load
versus mid-span lateral deflection relationships are geometrically nonlinear. The general mode of
failure is the flexural-torsional buckling. The eccentrically loaded specimens are failed at buckling
loads lower than their concentric counterparts. Overall, the critical buckling moment decreases as the
magnitude of eccentricity increases. Additionally, it is noticed that L/d ratio increases, the critical
buckling moment is decreased.

Abstract. The Micro arc oxidation is a powerful and mostly new process for improving and changing
surface peroperties of metals that can make oxidation layers on light metals like aluminium,
magnesium, titanium and their alloys. High hardness, high thickness, good adhesion to the substrate,
high thermal stability and insulation properties of oxide layers grown by this method. Application of
micro-arc oxidation on mobile covers, car pistons, hubs and rims for cars and so on. In metallurgical
engineering, there are different criteria that affected on coating on surface of the material such as
physical, chemical, mechanical, electrical and economical properties. In this study, the most important
parameters in the coating are titanium dioxide nanoparticles, time and the potential. The only
parameter that certainly specified is time and choose 5 minutes for optimum. Using the Analytic
Hierarchy Process (AHP), the performance of criteria for priority by addition of different
concentration titania (TiO2) nano particles in electrolyte and applying voltage on substrate MAO
method has been calculated. The titania particles with an average grain size of 10 nm in different
concentrations were added to a solution electrolyte which were coated on aluminum sample. The AHP
determined that the most favorable concentration of titania particles is 5gr/lit and worst voltage is 250
volts.

Jul Endawati, Lilian Diasti
Politeknik Negeri Bandung, Indonesia
Abstract. The composite element of 20 mm in thickness were manufactured using high volume fly
ash, silica fume as alternative hydraulic binders and Portland cement Type II. Pine wood shavel as by
product of local small wood working industries were used as the composite filler. The elements were
given in situ wet and dry treatment for 9 months. Visually there is no fiber degradation as a result of
the interaction of the environment. The assessment were done to the elements bending strength and
dimensional properties. Increase in MoRafter 180 days of exposure shown that mechanically, this
degradation is not seen yet. The increment of MoR (213%) compare to that of 28 days might be
affected by the formation of calcium hydroxide (CH) or ettringite in the transition zone. The use of
pozzolan showed also a delay or minimize degradation of composites while improving the pore
structure, and minimize the mineralization of the fiber bond with the cement matrix. The water
absorption is 4,22% at 180 days, 7,94% at 120 days and 12,38% at 28 days, in line with the 68%
decrease in Thickness Swelling (TS). This unoccured degradation could also be affected by the
presence of silica fume in the binder matrix. After 270 days of exposure under tropical condition, the
flexural strength started to decrease.

Michael Tan, Mary Donnabelle Balela
University of the Philippines
Abstract. We report a one-pot, low temperature process for the synthesis of high-aspect ratio copper
nanowires in aqueous solution for 1 hr. Ethylene diamine (EDA) was utilized to promote anisotropic
reduction of Cu(II) by hydrazine. Cu nanowires with mean diameters around 90 nm and lengths
exceeding 50 µm were synthesized using 180 mM EDA at 60oC, giving an effective aspect ratio of
about 450. Without EDA, nanoparticle growth is observed. The synthesis temperature was also
significant in limiting nanoparticle formation. Decreasing the temperature resulted to 1D growth and
fewer nanoparticles.

were investigated using optical microscope and scanning electron microscope. The result shows that
polypropylene-kenaf composite with 50%-50% fraction with random fiber orientation has
complicated fracture features. The damage of the composite started from internal part. The surface
crack proceeded after the internal damage. Moreover, it is discussed that some of fibers were covered
by only thin matrix. The strength of specimen was determined the fracture behavior of fibers.

Abstract. The objective of this study is to prepare α-cellulose reinforced poly(butylene succinate)
composites (PBS/α-cellulose). The effect of amount α-cellulose on the mechanical properties of the
composites was investigated. To improve interfacial interaction between PBS and α-cellulose,
glycidyl methacrylate grafted poly(butylene succinate) (PBS-g-GMA) was used as a compatibilizer.
Mechanical properties of PBS composites prepared by using a twin-screw extruder were investigated.
The mechanical properties of PBS/α-cellulose decreased due to the agglomeration of α-cellulose.
Nevertheless, tensile strength, Young’s modulus and flexural strength of PBS composites were
improved after the incorporation of PBS-g-GMA. The optimum loading of PBS-g-GMA and
α-cellulose in the PBS was found to be 5 and 6 phr.

Abstract. The modified poly(butylene succinate) (PBS), namely, PBS-g-MA and PBS-g-GMA were
prepared in order to be used as a compatibilizer for PBS composites. The grafting of maleic anhydride
(MA) or glycidyl methacrylate (GMA) onto PBS was carried out using a twin-screw extruder. The
grafting reactions were confirmed by spectroscopic analysis. Comparing with MA, it was found that
GMA can be effectively grafted on PBS. The PBS-g-GMA was successfully used for PBS composites
to enhance thermal properties. Furthermore, it was found that the incorporation of compatibilizer
increased the melt viscosity of PBS composites.

Chulalongkorn University, Bangkok, Thailand
Abstract. The goal of this work is to study the physical properties of bio-based polyurethane (PU)
foams prepared from synthesized bio-based succinate polyols. Bio-based succinate polyols were
synthesized by condensation reaction using succinic acid (SA) and four types of glycols that are
diethylene glycol (DEG), triethylene glycol (TEG), tetraethylene glycol (TTEG) and Glycerol (Gly).
The effects of glycol types (single or mixed glycols) used in the prepared polyols toward physical
properties of PU foams were studied. Physical and mechanical properties of the prepared PU foams
were taken relatively to PU foam obtained from a commercial polyol. The results revealed that

hydroxyl number (OH number) and viscosity of prepared polyols decreased as the length of the glycol
chains increased (DEG < TEG < TTEG) in both polyols prepared from single glycol and mixed
glycols.
However, the polyols prepared from mixed glycols showed higher viscosity than those
prepared from single glycol. Optical micrographs images showed that the PU foams prepared from
mixed glycol polyols had smaller cell size and more closed cell contents compared to ones prepared
from single glycol polyols. Time used in foam formation and density of foams prepared from
DEG-glycerol mixed glycol polyol were similar to one prepared from commercial polyol
(POLIMAXX A8360). However, compressive strength of foam was higher than one prepared from
commercial polyol.

Islamic Azad University, Amol, Iran
Abstract. Using the methods which are applied for estimating strength and toughness of composites
reduces trial-and-error rate in their design. One of the mechanisms for strengthening and increasing
toughness of composites is through debonding mechanism. Interface strength of reinforcement with
matrix and effective surface of debonding greatly affect toughness and strength of these types of
materials. In this study, a model was proposed to estimate the effect of interface and matrix strength
of composites in increasing tensile toughness and strength. Then, interface strength and its effect in
increasing tensile toughness and strength were calculated in a case study of composites containing
particle reinforcement in matrix of deep cryogenic treated steel.

were grown using sol-gel immersion method with MgZnO as the seeded catalyst and
thermal chemical vapour deposition was used to synthesise CS. Different configurations
of ZnO/CS structures were prepared i.e. CS-coated ZnO and ZnO-coated CS. The
structures of composite samples were analysed using field emission scanning electron
microscopy (FESEM) and micro-Raman spectroscopy. FESEM observations revealed the
structural changes of pristine ZnO and CS in composite structures. The as-presence of
ZnO or CS was believed to affect the subsequent growth of another structure. Field
electron emission (FEE) properties of both nanocomposites were also investigated. It was
found that ZnO-coated CS sample has better FEE properties with lower turn on (3.48
V/µm) and threshold field (6.35 V/µm) obtained at current density of 0.1 and 1 µA/cm2,
respectively. This study highlighted that nanocomposites of ZnO and CS have
successfully enhanced the field emission performances of materials compared with
pristine ZnO or CS due to the structural changes of material emitter.

Development of an Intelligent Database System to Automate the Recognition of
Machining Features from a Solid Model using Graph Theory
A. K. Verma, Rachna Verma
J.N.V. University, Jodhpur, India
Abstract. Automatic recognition of machining features is essential for the integration of CAD and
CAM. Graph-based recognition is the most researched feature recognition method as the B-Rep CAD
modelers’ database uses graph to store the model data. A graph-based feature recognition system uses
attributed graphs to store CAD models as well as machining feature templates. The graph
isomorphism is used to extract features in the model graph and template graphs. There are two main
research issues in this system- (1) Efficiently recognize the features as the graph isomorphism is
computationally every expensive and (2) inclemently expanding the feature template database to
include new features without any structural change in the recognizer. In this paper, the application of
feature vectors (a heuristic developed by the authors that converts a feature graph into a unique vector
of integers irrespective of the node-labeling scheme used by B-Rep modelers) to automatically expand
the recognizer’s feature template database is presented. It facilitates automatic inclusion of new
features in a feature database without requiring any additional programming effort from the user or
any changes in the structure of the recognizer. The proposed system has been implemented in Visual
C++ and ACIS solid modeling toolkit. Further, the proposed system is intelligent as it has the
capabilities to learn from the examples to incrementally build the feature database.

Adaptive Fuzzy Sliding-Mode Position Control of A Shape Memory Alloy Actuated
System
Suwat Kuntanapreeda
King Mongkut’s University of Technology North Bangkok, Thailand
Abstract. Shape memory alloy (SMA) actuators are promising for miniature applications. They
accomplish the shape memorization via a temperature dependent phase transformation process.
Control of SMA actuators is challenging because the actuators exhibit highly hysteresis behavior.
This paper presents a fuzzy-based position control scheme for a SMA actuated mass system. The
control system consists of an outer- and an inner-control loop. The inner loop controls the temperature
of the SMA actuators using a PI controller, whereas the outer loop, which is affected by the hysteresis
of the SMA actuators, controls the position. To deal with the hysteresis in the position control loop, an
adaptive fuzzy sliding-mode control method is adopted. Experimental results illustrate the success of
the proposed control scheme.

Abstract. Japan is becoming a super-aging society, with a population decrease and a shortage of
young workers. Mechanisms using pneumatic cylinders are therefore expected to be useful to perform
tasks such as day-to-day work support for elderly people. However, pneumatic cylinder includes large
dead time. Thereby, traditional control system is complex, such as adding Smith compensation.
Therefore, we use Predictive Functional Control (PFC). This control system is not complex even if
plant includes dead time. This study evaluates the performance of force and position control systems
using a pneumatic cylinder and PFC. We compare the PFC scheme with the PID control and show
that PFC achieves better performance than PID control.

Abstract. This paper addresses a two-degree-of-freedom control system design for positioning
devices such as table drive systems based on the predictive functional control (PFC). The aim of the
paper is to improve the tracking performance of the previously developed disturbance observer-based

representation of the PFC controller. On the basis of the representation, we apply the zero phase error
tracking controller (ZPETC) as a feedforward preview controller. Experiments using a real table drive
system are conducted to compare the proposed control system with DOB-PFC. The experimental
results show that the tracking error is greatly reduced compared to DOB-PFC.

A Framework of In-Situ Model Error Compensation for Adaptive Robotic Task
Execution
Yazhini C. Pradeep, Shengfeng Zhou, Audelia G. Dharmawan, Kevin Otto, I-Ming
Chen and Peter C. Y. Chen
National University of Singapore
Abstract. In precision robotic applications, inaccuracy in workpiece geometry has been a common
problem to the precise processing of the workpiece. Due to manufacturing defects and workpiece
deformation, the actual geometry of the workpiece deviates from its nominal 3D CAD model which is
defined as model error. For many of the existing industrial robotic applications today, the robot path
for processing the workpiece is planned based on the nominal 3D CAD model of the workpiece.
Hence, the model error of the workpiece leads to error in the robot path planning eventually inducing
inaccurate processing. To enhance the accuracy of the robot in processing the workpiece, a framework
for in-situ model error compensation has been proposed. Prior to the processing of each workpiece,
the proposed technique employs 3D optical laser scanning technology to capture the actual 3D model
of the workpiece and compares it with the nominal model to establish the model errors. The nominal
path of the robot initially created based on the nominal CAD model is then modified according to the
model error. Thus, this step performs the in-situ model error compensation making the robotic task
adaptive to the actual workpiece geometry. Experiments have been conducted to verify the proposed
framework and an accuracy of up to 30 micrometers has been achieved in model error identification
and compensation. The proposed technique can be employed in applications such as high precision

Abstract. Many pneumatic actuators have been developed in order to be lightweight with high output
for decreasing impact force. So far, a pneumatic tendon-driven balloon actuator (balloon actuator)
which is compact and lightweight has been developed for a robot hand and a rehabilitation device.
However, for pneumatic actuator, it is difficult to maintain exact control because these actuators have

constrained model predictive control (MPC) scheme that can consider constraints of the plant output.
As described in this paper, we compared and evaluated the control performance using MPC and PID.

National Institute of Technology, Durgapur, India
Abstract. The present paper deals with a detail inverse dynamics and power consumption of a
realistic hexapod robot with crab motion. The prescribed motion parameters necessary for the inverse
dynamic analysis like displacement, velocity, acceleration of the joints are obtained from the
kinematic analysis and motion planning of the hexapod robot. The foot ground interaction is
considered as a point contact with zero impact velocity. The solution to the problem is not unique due
to a highly redundant robotic system. An energy consumption model has been derived for statically
stable wave-crab gaits after considering a minimum of the instantaneous power consumption of the
robotic system for optimum feet forces. Minimum of power consumption is considered as the
objective function with respect to linear equality and inequality constraints. The simulated results and
discussions of the inverse dynamic analysis of the robotic system with crab motion on regular terrain
are discussed.

King Mongkut’s University of Technology Thonburi, Thailand
Abstract. The design of lower limb rehabilitation robot can be categorized into two approaches: the
end-effector and the exoskeleton. Both types of the robots have different advantages and
disadvantages. The exoskeleton type is designed to mimic the kinematic structure of the human
skeleton by controlling hip and knee joints but the end-effector type is driven at the footplate which
allows patients to perform various gait training exercise. In this paper, the end-effector and
exoskeleton device are compared based on dynamical analysis using Matlab's Simechanics
simulation. The hybrid lower limb rehabilitation robot is also proposed based on the exoskeleton robot
with the adjustable mechanical coupling interface between human and robot and the active footplate.
The hybrid design combines the advantages of both the exoskeleton and the end-effector by allowing
the mechanical coupling parameters and the active footplate controller to be adjustable at different
stages of training. The proposed design can improve both joints misalignment and joint trajectory
tracking problems in both existing approaches.

Abstract. Project Management Information Systems (PMIS) is considered to be advantageous to
project managers to address critical project information needs and widely become an important means
of achieving overall success for many organizations in the rapidly changing business environment.
Ministry of Works (MOW) in the kingdom of Bahrain has implemented Project Management System
(PMS) based on the Project Management Institute (PMI) best practice and subsequently the PMS was
automated to be (PMIS). This paper aims to assess the level of PMIS’ success from project manager’s
perspective at the MOW. This has been done through a survey based on DeLone and McLean model
of information system success. The results showed that the use of PMIS is advantageous to project
managers as IT tool, but it needs further customization to improve effectiveness and efficiency of the
managerial tasks in terms of better project planning, scheduling, monitoring and control. The results
showed that 49.3% of the project managers handle 3 projects or more at the same time, which may
have affected negatively on the information quality due to the complexity of the system and the time
needed to keep the information up-to-date, also only 34.2% of PMs received sufficient information
that enables them to complete their job on time. The scores of the model dimensions are presented in a
descending order as follow: system quality (82%), service quality (77%), system use (72%), user
satisfaction (70%), net benefit (69%) and information quality (67%). The score of information quality
reflects its inadequately and instability. The results revealed that there is a strong positive correlation
between user satisfaction and net benefit with coefficient of correlation (r = 0.868). Information
quality, system use, system quality and service quality have a moderate positive correlation with the
net benefit, which were statistically significant (r = 0.701, 0.626, 0.432 and 0.404) respectively. The
study recommends that PMS methodology should be enforced and the distribution of projects load
should be done in an organized manner. In addition, PMIS must be amended according to the roles
and responsibilities of project managers and project administrators.

Abstract. This paper describes the human face detection based on special feature color. Here, the skin
color was picked up as a special feature. The human’s face was observed by the USB camera in real
time. First of all, human face images were obtained under the various brightness environments. As a
results, it was found that red component of the facial skin is stronger than any other facial parts such
as eye, nostril or mouth.In our proposed system, the original image was changed into the rough color
image and the smoothing procedure was applied to calculate the weight value of the skin color and
eliminate noise. In cases where the head was tilted or the face was turned to the side, it is difficult for
theexisted method to detectthe face, because it was adjusted for the frontal face. On the other hand,
our proposed system could detect the tilted face and side face.

Abstract. Demand for data storage devices such as hard disk is rapidly increasing as almost every
aspect of modern life has been digitized. Presently, one of the main challenges for storage
manufacturers is to reduce operational cost while increasing the customer satisfaction so that the
company can survive in the fierce competition. Recognizing the necessity of continuous functional
improvement, this paper has adopted a Value Engineering (VE)-based methodology for product cost
reduction in the manufacturing process of hard disk components. Value Engineering has been
recognized as a powerful technique to achieve value enhancement and cost reduction. Toward this, the
7-phase work plans were developed within the framework of the VE methodology. This proposed
approach has been implemented and validated in a case study, which focused on head stack assembly
(has) process to reduce cost and improve quality. Application results showed that the indirect

One-day Tour in Singapore
The Merlion (Malay: Singa-Laut) is a marketing icon with the
head of a lion and the body of a fish, used as a mascot and
national personification of Singapore. Its name combines
"mer" meaning the sea and "lion". The fish body represents
Singapore's origin as a fishing village when it was
called Temasek, which means "sea town" in Javanese. The lion
head represents Singapore's original name — Singapura —
meaning "lion city" or "kota singa".
Mount Faber is a hill about 105 metres (344 ft.)
in height in Singapore, located near the Bukit Merah planning
area in the Central Region. It overlooks the Telok
Blangah area, and the western parts of the Central Area. The
summit is accessible by road, but there are many footpaths
leading up the hill. It is a frequent tourist destination, as it
provides a panoramic view of the increasingly dense central
business district within the Central Area. Its slope includes a tower that is part of
the Singapore cable carsystem that connects to HarbourFront and Sentosa. It is
accessible from the HarbourFront MRT Station.
The Singapore Botanic Gardens ( Malay: Taman Botanik
Singapura or Kebun Botani Singapura) is a 74-hectare
(183-acre) botanical garden in Singapore. It is the only
botanic garden in the world that opens from 5 a.m. to 12
midnight every single day of the year, and does not charge an
admission fee, except for the National Orchid Garden. The
garden is bordered by Holland Road and Napier Road to the
south, Cluny Road to the east, Tyersall Avenue and Cluny Park Road to the west
and Bukit Timah Road to the North. The linear distance between the northern and
southern ends is around 2.5 km (1.6 mi). In December 2012, an application for it to
be listed as a UNESCO World Heritage Site was made.
Sentosa is a popular island resort in Singapore, visited by
some five million people a year. Attractions include a 2 km
(1.2 mi) long sheltered beach, Fort Siloso, two golf courses,
two five-star hotels, and the Resorts World Sentosa, featuring
the theme park Universal Studios Singapore.
