Abstract - One of the main issues with the different industries today is to manufacture
products that help in elimination cost as well as works towards waste reduction. These
and many other industries related problems had led to the formation of lean
manufacturing, a method that was initially implemented by Toyota of Japan. However,
there is very little, almost no research that is done on lean manufacturing in Malaysia
and there is a lot of struggle that Malaysian manufacturing industry is facing in the
implementation and sustenance of lean principles as well as policies. The present
project research is an attempt to find the challenges or issues that Malaysian industries
are facing in order to implement and successfully sustain the lean manufacturing
processes. The researcher would try to investigate on the topic by taking mixed
analysis method, where both primary and secondary researches would be conducted.
This research would also take in the different principles and concepts in lean
manufacturing and collate it with the primary findings. Overall, this study can be used
as a benchmarking for successful lean manufacturing implementation in other
developing countries.

Abstract- An investigation on the properties of Tenun Pahang fabric performances using
alternative yarns was conducted. The studies made in order to evaluate whether the Tenun
Pahang fabric could be produced economically and at the same time maintain the fabric
quality. Traditional Tenun Pahang fabric uses silk for both warp and weft. For this project,
two alternative yarns were used, there were bamboo and modal, these yarns were a little
lower in cost compared to silk. These yarns were woven with two variants, one with the
yarns as weft only while maintaining the silk warp and the other with both warp and weft
using using the alternative yarns. Four (4) physical testing and three (3) mechanical testing
conducted on the fabric samples. These were evaluated including weight, thickness, thread
density, crease recovery angle, stiffness and drapability. The results show that modal/silk
and bamboo silk fabrics are comparable in terms of stiffness and drapability, hence they
have the potential to replace 100% silk Tenun Pahang.

Abstract- The Lean appears to have numerous definitions while exploring the topic. The
principles of Lean are just a compilation of methods and tools which are implemented in an
organization to improve the efficiency and effectiveness of the organization. It is also true
that, the Lean principles mostly have undesirable outcomes. Sometimes, the organizations
do not achieve the expected success which forces them to desert the Lean principles while at
times they find it difficult to sustain the improvements, again making them forcefully
conclude the Lean product development. These limitations or failures can be overcome by
recognizing Lean principles not only as a set of tools but also as a value. This paper aims
exclusively on effectively applying the Lean principles in the telecommunication sector to
improve the product development activities. For the study, the secondary data was collected
from various articles, journals, books and publications which are the works of various
researchers and authors. The study also carried out a case study of 2 giant companies in the
telecommunication sector, the Cisco and the Alcatel-Lucent. From the study it was observed
that companies employing Lean have effectively improved their processes and services.
Various impacts of the Lean principles were also encountered and the study also suggests
certain strategies to overcome the impacts or limitations of the Lean principle
implementation.

Abstract-Nowadays, metal injection molding has become among the capable method in
powder metallurgy research to produce small-scale intricate part at an effective process and
competitive cost for mass production. This study investigates the effect of injection
moulding parameters on the density of green part of Ti-6Al-7Nb. The titanium alloy powder
of Ti-6Al-7Nb is mixed with binder 40%wt of palm stearin and 60%wt of polyethylene as a
binder system. Taguchi Method with L18 orthogonal array have been used to optimize the
injection parameters while to minimize the test run and maintaining the quality standard of
data measurement. Parameters optimized are the injection temperature, injection pressure,
mold temperature, injection time and holding time. Finally, result show that the optimum
combination of injection factor that can be produces the best value of green density, which
eventually will leads to higher density for sintered parts.

Abstract- The paper focuses on the signal cross correlation in 3D scattering MIMO channel.
An improved geometrically-based 3-D wave scattering MIMO channel model is developed.
The fading cross-correlation in vertically (ε=90°) and horizontally (ε=0°) separated antenna
array at the MS was investigated in terms of the antenna element spacing, AoA distributions,
and the angular spread of the arrival angle in the vertical plane. An extended geometricallybased MIMO channel model in 3-D wave scattering is developed and general formulas for
joint spatial-temporal correlation, spatial correlation, and temporal correlations are derived
and numerically evaluated. Then the effect of this correlation on MIMO channel capacity is
investigated under assumption of uniform and Laplacian angular energy distributions and
for uniform linear array (ULA) and uniform circular array (UCA) using MATLAB
simulation environments.
Reducing the Power Envelope Fluctuation of OFDM Systems Using a Simplified
Amplitude Clipping Approach

(UniMAP), Kuala Perlis, Kangar, Perlis, Malaysia

Abstract- A new and crucial modulation technique that is being developed, under the
communication systems domain, is Orthogonal Frequency Division Multiplexing (OFDM).
The signals from OFDM can not only fight multipath propagation and fading channels but
also advocate huge rates of data. Nevertheless, OFDM too has its disadvantage as it is a
multicarrier system and can face issues because of the demanded summation of sinusoids
during the combination of the in-phase subcarriers, which in turn tends to produce high
power peaks. The performance of the BER can be degraded by the big fluctuations in the
power envelope called peak to average power ratio (PAPR), which causes in-band and outband distortion. There are a plethora of methods to solve the problem posed by the PAPR
that includes SLM – Selected Mapping, PTS- Partial Transmit Sequence and clipping of
amplitude. The former two methods are very complex, whereas amplitude clipping is seen as
a much simpler alternative for implementing real-time. This paper aims to provide an
alteration to the technique of amplitude clipping, by presenting a fresh method named SAC Simplified Amplitude Clipping. In the SAC method, extra bit of information is sent, in order
to ensure that all of the clipped data is retrieved by the receiver. Furthermore, the SAC
method is not complex and results from the simulations advocate the point that this
3
005-iccae
technique is more adept than the original one. The size of the mean squared error vector
stays the same when compared to the conventional unclipped signal, whereas the PAPR
reduced by approximately 1.0dB. On the other hand, the ordinary clipping method makes a
much larger magnitude of mean squared error vector.

Abstract- Nowadays, energy storage improves the reliability and efficiency of electric
utility system. The most common device used for storing electrical energy is battery.
Obtaining an accurate data of battery parameter is important because it will be avoid
unexpected system interruption and prevent permanent damage to the internal structure of
the batteries. The objective of this study is to apply time-frequency distribution (TFD) which
is spectrogram technique in analysis of voltage charging and discharging signal for lithiumion battery. Spectrogram represents the battery signal in time frequency representation
(TFR) which is appropriate to analyze the signal before displaying the instantaneous RMS
voltage (Vrms), direct current voltage (VDC) and alternating current voltage (V AC) parameter
value. This paper focuses on lithium-ion (Li-ion) battery with nominal voltage of 6 and 12V
and various storage capacities from 5 to 50Ah. The battery model is implemented in
MATLAB/SIMULINK. From the results, the Li-ion battery parameter could be identified
using spectrogram.

enhanced the reliability of the inverter. This paper present a new approach for switches
faults classification and identification system in VSI. The phase current signal extracted
from VSI is represented in time-frequency representation (TFR) using S-transform
technique to estimate signal parameter and characteristics. The performance of the system
are then analyzed and compared between, simulation, actual and system.

Abstract- Proton Exchange Membrane Fuel cell (PEMFC) is one of the renewable energy
system that was recently highlighted by researchers. However, the improvement of PEMFC
becomes complicated as there have been various parameters and characteristics from the
Fuel Cell which have not yet to be discovered deeply. Identification analysis is required to
monitor every factor that influences the performance characteristic of PEMFC. Thus, this
review indicates that the research and analysis of PEMFC by using the Periodogram are still
not widely explored. An experimental study has been performed to monitor a variety of
hydrogen pressures acting as fuel at anode side of PEM Fuel cell by using Periodogram.
This experiment has practically researched the various hydrogen (H2) pressures between 0.1
bars until 0.5 bars and the constant air flow at cathode side. It indicates that the voltage
performance and amplitude from the Periodogram data of the PEMFC changed as the
pressure of hydrogen at the anode side changed. Apart from that, the signal characteristic of
direct current voltage (VDC), root means square voltage (VRMS), and alternating current
voltage (VAC) also changed as the hydrogen pressure changed. Therefore, the relationship
between the hydrogen pressures at the anode side towards the signal characteristic of
PEMFC could be monitored by using Periodogram.

Abstract- In this paper, we study the optical properties, the surface roughness and the
topography of Si and SiO2 substrates-coated with PMMA film layer using UV-Vis-NIR
Spectrometer and atomic force microscope, AFM. The spectral analysis on the results
obtained shows high absorption and low reflection of light on PMMA/Si, but low absorption
and high reflection are observed on an uncoated Si. High transmission is recorded on
PMMA/SiO2 in which more than 92 % transmission is recorded between 800mm and
1000mm. On the other hand, the results on the surface roughness obtained shows that the
PMMA film layer reduces the root mean square roughness of both Si and SiO2 substrates,
while plasma treatment on SiO2 increases its surface roughness.

Abstract- Background: The microwave dielectric properties of Zn(1-x)CoxAl2O4 thin films
were examined with a view to their exploitation for GPS antenna. The Zn(1-x)CoxAl2O4 thi
n films were prepared by the sol gel method at 500 °C for 1 h. Co addition decreased the cr
ystallite size and surface morphology of the resultant films, evidently affecting their density
and dielectric constant (εr). Based on the material investigated and microwave antenna theo
ry, GPS patch antennas were fabricated using Zn(1–x)CoxAl2O4 and then studied using a P
NA series network analyzer. The measured results show that antennas had the return loss an
d impedance bandwidths of -16.6 to -20.3 dB and 75–180 MHz, respectively. The GPS patc
h antenna fabricated from Zn0.85Co0.15Al2O4 showed an excellent combination between t
he return loss (-20.3 dB), small in size (4.68 x 3.13 cm2) and wide bandwidth (180 MHz).

Abstract- Zinc aluminate (ZnAl2O4) and zinc ferrite (ZnFe2O4) nanocrystalline structures
dispersed into SiO2 matrix were prepared by sol-gel method. Phase formation of ZnAl2O4
and ZnFe2O4 was confirmed by X-ray diffraction (XRD) analysis. The crystallite sizes was
determine using Scherer’s equation from the broadening of dominant peak at (311) plane. It
was found the crystallite size of both compound decreased due to the decrement
compositions of Zn2+ ion and Al3+ / Fe3+ ions. The crystallite sizes for ZnAl2O4 and ZnFe2O4
was calculated to be around ~ 14.16 – 11.27 nm and ~ 11.27 – 4.72 nm, respectively. FTIR
analysis was done to determine the formation of spinel structures. FTIR results analysis
confirmed that the formation of spinel structure where it has been observed that the bands
around 800 cm-1 was associated to the vibrations of aluminum-oxygen and metal-oxygenaluminum bonds. This characteristic was identified to the formation of zinc aluminate spinel
structure. The optical properties have been done to determine the energy bandgap of
ZnAl2O4 and ZnFe2O4 samples. The Uv-Visible absorption spectra have been done within
wavelength 300 – 800 nm and the graph was plotted into the Tauc plot. This new dielectric
material was purposed to improve the value of dielectric permittivity with addition of SiO 2
where it can be applied as microwave dielectric material without changing the original
spinel structures.

utilised in photoelectrochemical (PEC) water splitting process for solar hydrogen fuel
conversion. However, the overall solar conversion efficiency is still relatively low and this
could be due to the rapid recombination of photogenerated charge carriers at molecular
level. Objective: The main aim of this paper was to understand the effect of annealing
temperature on the photogenerated charge transfer in nanostructured tungsten trioxide
(WO3) thin films synthesized via electrochemical deposition route. Results: Amorphous
WO3 films were annealed between 100oC and 600oC. It was found using electrochemical
impedance spectroscopy (EIS) that both the charge-transfer and transport resistances
decrease with increasing annealing temperature. Conclusion: This study concluded that a
properly controlled annealing treatment is crucial in regulating the nanocrystals growth,
which subsequently enhances the photogenerated charge transfer and solar conversion
efficiency for sustainable hydrogen production from water splitting.

Department : Chemistry, Faculty of Science, University of Malaya
Abstract- Liposomes as effective drug delivery vehicles have played significant role in
therapeutics. However physicochemical instability of liposomes reduces its possibilities and
potentials to be used in drug delivery systems. The present work describes the stabilization
of liposome via electrostatic deposition of a polycationic derivative of dextran which is
Diethylaminoethyl Dextran (DEAE-Dx) on soy lecithin liposome. Liposomes were prepared
by thin film hydration method. The critical vesicular concentration (CVC) of lecithin was
found at 0.3 % (w/v) through surface tension analysis. Zeta potential was obtained to study
the interaction between DEAE-Dx and liposomes. The zeta potential of liposomes changed
from negative value to increasingly positive after addition of DEAE-Dx. This confirmed the
coating of liposomes by DEAE-Dx. Stability of the DEAE-Dx liposome suspension was
studied through particle size and zeta potential measurements over a period of 5 weeks.
DEAE-Dx liposome suspension was found more stable than the uncoated liposomes
suspension. The optimum concentration of DEAE-Dx was observed at 0.04% (w/v)
compared to other examined concentration of DEAE-Dx. Interestingly, entrapment
efficiency of coated liposome loaded with curcumin shows a higher value compared to the
uncoated ones.

Abstract- Incredible innovation in the degree of biocompatibility and biodegradability
regarding drug delivery carriers has revolutionized a breakthrough in the liposome
formulations. These transporters loaded by either a drug or any other therapeutic agent, have
unlocked horizons to investigate novel drug delivery systems (DDS). In a certain
environment, an absolute control over their broad applications associated to both temporal
and spatially controlled drug delivery offers potential capabilities in different clinical
situations. Among all the cellular carriers including leukocytes, fibroblasts, islets, and
hepatocytes, red blood cells (RBCs) offer several distinctive features. Incorporation of
natural and artificial external stimuli even triggers the drug released profiles with more
effective site-specific targeting. The present study underlines a discussion on such RBC
carriers ( both natural and RBC mimics) which can evade body’s reticuloendothelial system
(RES) overcoming many barriers such as size, shape, accelerated blood clearance,
mechanical properties, control over particle characteristics, and surface chemistry. Bilayer
membrane liposomes infusing phospholipids have long been synthesized to mimic
bioconcave Red Blood Cell (RBC) carriers using the notion of stealth liposome. The present
research aims to compare red blood cell as natural and synthetic carriers to accord with
immune system as a game of hide and seek in a much promising manner. No wonder a lot is
yet to be revealed on its worth in view of both in vitro and in vivo loom.

Abstract- Titanium dioxide (TiO2) nanotubes was synthesized by hydrothermal method
and calcined at different temperature (300, 400, 500, 700°C) for 2 hours to study the effect
of different calcination temperature on the physical properties and photocatalytic activity of
TiO2 nanotubes was studied. The anatase phase structure of the TiO2 nanotubes is
remained even after calcination at highest temperature studied of 700 °C. However, their
morphological structure transformed from nanotubes into nanoparticles after calcination at
higher temperature. Hence, reduces the photocatalytic activity of TiO2 material in
degrading methyl orange due to the decreases in surface area and porosity of the materials.

Abstract- Management today‟s world is about management in times of rapid change.
The need to develop better leadership styles is becoming increasingly important in all
organizations. The purpose of this work is to ascertain if there is a relationship between
the leadership styles and the employees‟ performance, particularly in the Telecom
Engineering companies, meanwhile to determine the relationships between leadership
styles and employees' job performance through the mediators: employees' motivation,
job‟s satisfaction; whether these relationships will be stronger for Transformational than
for Transactional leaders, Laissez-Faire leaders or Servant leaders. This project reviews
as well four recent and widely utilized leadership styles: transformational leadership,
servant leadership, transactional leadership, and Laissez-faire leadership. There is a lack
of total agreement in the reviewed literature as to the best leadership style to be used.
Transformational theory is considered by many to be an improvement to the transactional
theory of leadership. There appears to be an ever increasing number of studies supporting
the benefits of the transformational theory. In today‟s ever changing climate, there are
some researchers whose findings suggest the optimal leadership style may be a blend of
Servant, transactional and transformational styles. Quantitative research method would be
practice in this research. The questionnaires will be distributed only to employees in the
Telecom Engineering companies. Structural Equation Modeling (SEM) and SPSS are
approach which will be used as a tool to analyze the results in future in this research, due
to the complexity of the model and the limitation of multi dimension analysis tools in
quantitative research such as multiple regressions, factor analysis, and discriminant
analysis. A proposed theoretical framework of this work has been decorticated in this
paper.

Background: By the use of hermeneutical phenomenology, rich students’ field trip reports
are studied in order to understand the context and the dynamics of the interplay of tourist
experience with their private preference spaces and the externally experienced context or
environment. Objective: The overall aim of the study is to explore what is typically
embedded to mean a tourist experience, its characteristics or nature, how a great experience
could be narrated or depicted and the student-as-tourist’s attitude towards the study tour trip.
Results: The findings reflect sound validity and reliability as per the generally
acknowledged quality criteria of a realism-based qualitative research approach. Construct
validity is evidenced also by the alignment between the propositions posited and the
significant sets of the students-as-tourists’ experience statements, coupled with
hermeneutical cycling of data analysis, member checking and similarity of phenomena
shared in other proven theories such as attribution theory, motivational theory of consumer
behavior, and value co-creation concept in strategic management discipline. Conclusion: A
model is proposed that reaches into the interpretative domains of the study field trip
experience by examining how the students make sense of their trip experience and the
implications they draw.
