In this study, a new All-Optical Packet Routing (AOPR) Time Wavelength Division Multiplexing (TWDM)
Passive Optical Network (PON) TWDM PON system was developed. The system provided flexible data
delivery for each PON port and bandwidth for each subscriber at multiple PON Optical Distribution
Network (ODN) links. The proposed AOPR module was designed to incorporate fixed-type wavelength
Optical Line Terminal (OLT) transmitter with Continuous Wave (CW) Pump Probe Signal (PPS) module. The
new design used high-speed Wavelength Selective Switch (WSS) or ALL ON method to support the high-
speed wavelength switching or all broadcast signal to replace the wavelength tuning feature in tunable
OLT transmitter. It had the ability to perform flexible packet routing function using WSS with 38 dB
allowable link loss margin at 10 Gbps at Bit Error Rate (BER) of 10-3. The proposed design minimized the
inventory issue and reduced the point of error caused by different OLT PON port transmitter wavelength
during the system installation and maintenance.

In general, companies undergo transformation due to industrial competitors. However,
they fail to change at the subjective level due to resistance. Therefore, there is a need to
construct a communications strategy to find the cause of the failure. Resistance to change is
a result of a poor fit between the organization and the industry’s best practices. By
understanding how habits work, interventions with modified or new routines based on
best practices has influenced the change habits, reduce resistance to change, improve
quality, productivity and delivers successful projects. Accordingly, the present study
investigated the resistance to change by assessing the causality and developed a suitable
mediating mechanism (change initiative). Several projects were identified and used as a
case study. Interviews and questionnaires were used to gauge the resistance to change
within the organization.

Saturated brine in chlor-alkali plant contains impurities such as Mg2+, Ca2+, Fe2+ and SO42− that affects the
performance of the primary brine processing. Clarifier and brine filtration system is used to produce
clear and low suspended solid contained brine. When the total brine production was increased from 35
to 68 m3/hr, the total retention time was reduced by half in the clarifier and affect the settling of the
suspended solid. Therefore, the carryover of suspended solid caused premature loading to the brine
filtration system and caused problems to the filter operation. As a result, this study provided a method
to improve the weight ratio of Calcium and Magnesium in the primary brine. Studies were performed to
increase the ratio, and a solution is proposed for the clarifier system. The aim was to reduce the
suspended solid by 20% before it enters the brine filtration system.

Corrosion and erosion in pipes are a major concern within the chemical industry
specifically during the transportation of corrosive chemicals in steel pipes, where both can
lead to potential unscheduled plant down time. In this work, the application of guided
waves technology to address this industrial problem was quantitatively assessed in terms
of technical capabilities, economic feasibility and suitability to be incorporated as part of
the industry’s risk-based inspection programmes. The technical capabilities were
qualitatively and quantitatively assessed through nine performance objectives, which
were formulated to determine its adaptability in the industry. Results showed that the
technology was suitable for the detection of common defects in the plant for 12” sulphuric
acid pipelines, typically pit and patch corrosion that was induced by hydrogen grooving
and erosion respectively. A new inspection procedure that incorporates the use of guided
wave along with the other conventional Non-Destructive-Testing (NDT) methods were also

The research focused on the experimental and Finite Element (FE) simulation for the evaluation of the
extent of plastic localization, ductile damage level and residual plastic strain retained in a component
after a deep drawing process of mild steel and Advanced High-Strength Steel (AHSS) material. The
ultimate goal of the present research was to formulate a state variable for plastic pre-strain and damage
levels of sheet metal parts after a deep drawing process. The constitutive law was coupled with the
conventional structural FE analysis. An inverse approach, based from correlation studies with FE simulation
methods, was adopted to obtain parameters that are not readily obtained through the physical test. In
addition, results from the simulation method were analyzed to examine the failure characteristic of the
specimen. A state variable as a function of plastic strain, strain path, anisotropy and thinning was
established to define the material characteristics at the end of the forming process. The influence of deep
drawing process to the extent of material damage that characterizes the state variables was also
investigated.

Radio over Fiber (RoF) system is one of the key technologies for next generation access networks.
Increased requirement in the volume of wireless data transmission has stimulated attention on ways to
use the millimeter wave (mm-wave) band above 40GHz as the carrier frequency. By using RoF system,
a large propagation loss of the mm-wave signal in space or a cable can be eliminated. One of the key
components in photonic mm-wave RoF systems is a high speed, high responsivity and high power
Photo Detector (PD). The aim of this research was to design, simulate and fabricate the mm-wave PIN
PD module operating between 1330nm and 1550nm with integrated Low-Temperature Co-fired Ceramic
(LTCC) packaging. LTCC process was chosen due to its superior capabilities in thermal management,
temperature resistivity and heterogeneous system integration (matching different TCEs). The novelty of
this research was the integration of mm-wave photo detector module with LTCC packaging.

The aim of this research was to determine the significant process parameter for Polyurethane Flexible
Foam molding in close cavity mold. Specifically, the objectives of the study were to analyze the

correlation of molding process parameter with the Polyurethane Chemical characteristics and to develop
a robust process parameter to eliminate air voids and poor surface appearance in close cavity molding.
These studies also attempted to verify the obtained process parameters into actual close cavity foam

production in the company. Lack of stability in molded foam is normally evidenced as shear collapse, vent
instability or air voids (air trap). The severity of such instability is often related to the complexity of the

mold and total chemical volume injected to obtain required density and hardness of the foam. The
phenomenon can be caused by purely chemical factors of high viscosity, fast gel time and low flow ability
imbalance of blowing agent.

An algal bloom is a rapid increase in the density of algae in an aquatic system. Algal blooms sometimes
are natural phenomena, but their frequency, duration and intensity are increased by nutrient pollution.
Algae can multiply quickly in waterways with an overabundance of nitrogen and phosphorus. Algae
causes many issues with water treatment plant operations including: clogging of intake screens, fouling of
weirs, disruption of floc settling, production of algal mats, filter clogging from algae or from Extracellular
Organic Matter (EOM), increase coagulant demand, increased chlorine demand, increased disinfection by-
products, pH fluctuations, tastes and odors and release of algal toxins. The aim of this research was to
improve the coagulation process as a result of the algae interference, to obtain a suitable chemical
reaction or oxidation or physical process in order to remove the algae in the raw water before or during
the treatment process and to reduce the presence of residual algae in the treated water.

In practice, Design to Cost (DTC) has been used as a powerful strategy in many industries to meet
challenges and to stay competitive in the market. This study explored the knowledge of the DTC process
and the Theory of Inventive Problem Solving (TRIZ) in the industry. This research used case studies to
establish the explanatory power of competing theories. The proposed framework validated by a panel of
selected experts using the Delphi survey to calibrate the framework based on the data extracted and
analyzed from a semi-structured survey. The proposed integrated framework demonstrated a successful
application of TRIZ into the DTC process. Both innovation and cost improvement was achieved
simultaneously by adopting the TRIZ. The majority of the practitioners (92.5%) wanted to focus on the
problem-solving process in the DTC, with the Kendall's coefficient of concordance (W) of 0.78.

In car design, an ergonomic of driver seat accommodation and positioning in driver workspace is one of
the important areas that design engineer should consider during vehicle design activity. The objective of
having an ergonomic element in the design is to ensure the design of the driver workspace area is
harmonized and comfort to meet the driver expectation. Therefore, the aim of this research was to
investigate the applicability of the current design practices by investigating the anthropometric differences
of Malaysian drivers compared with the human manikin used by the Society of Automotive Engineers
(SAEs). The investigation was also performed on the driver posture difference compared to the current
design in a sedan car. A set of anthropometric data and a 3D model human manikin for male and female
was established, and the preferred driving posture was determined. Results showed that the Malaysian’s
have longer torso on body anthropometry compared to the SAEs data and shorter range of joint body
angle in driving posture.

Oil palm plantations by their nature are unable to rely heavily on mechanization, relying primarily on a
combination of high-skilled and low-skilled labor. This is both a strength of the industry as a poverty
alleviation mechanism, but also reflects a weakness when there is a shortage of labor, as the industry is
currently experiencing. If the estate is managed by the rules and requirements of plants, it will affect the
productivity improvement of oil palm Fresh Fruit Bunch (FFB). Criteria that must be considered is the land
selection, planting materials, technical management, harvesting and environmental. This research focused
on the production of FFB at Felda Cawangan Tembangau 6, Pahang, under the management of the Felda
Global Venture (FGV). The main objective of this research was to determine whether the innovative
technology used in this research; the Artificial Domestic Pollination System (ADOPSY) could be used to
produce high FFB yield in a sustainable manner. Data were analyzed quantitatively to obtain the
improvement in the production of the FFB using the ADOPSY. This new technology provided a great
opportunity to the palm oil industries in Malaysia. The study was carried out to determine the change
value in the numbers of FFB production compared to the untreated for one year.

The aim of this research was to design and develop the remote antenna unit downlink for Radio over
Fiber (RoF) system at a millimeter wave region, specifically at a frequency of 40GHz. The Remote Antenna
Unit (RAU) downlink consisted of Photo Detector (PD), amplifier, filter and antenna. The Photodiode was
used to convert the optical signal to electrical RF signal. This signal was amplified by the active elements
like Low Noise Amplifier (LNA), attenuator and Power Amplifier (PA). The passive elements like filter were
used to discriminate between wanted and unwanted signal frequencies and then connect to an antenna
to transmit the signal. A literature review was conducted to determine the specifications required for mm-
Wave Radio over Fiber that complies with Institute of Electrical and Electronics Engineers (IEEE) standards
especially at millimeter wave frequency. This was than followed by a review of the literature related to
the System on Package (SoP) using Low Temperature Co-fired ceramic technology for the development of
the millimeter band pass filter as main parts in remote antenna unit downlink.
