This Company is one of the largest multipurpose port in Malaysia which provides facilities
and services to handle variety of cargoes ranging from containers, cars, break bulk cargoes, dry bulk
cargoes and liquid bulk cargoes. The company divided into three main core business divisions which
are Container Division, Conventional and Logistics Services and Marine Divisions. Based on Pareto
analysis, Conventional & Logistics Services has the highest number of accidents with 75% of total
number of accidents in year 2014. In this company, the trend analysis of accident keep increasing
month by month. In this study using DMAIC approach, the objectives of this study is to improve safety
performance by decreasing the number of accident focused on Conventional & Logistics Division by
using six sigma approach. Six sigma is a quality tools for process improvement. It involved five phases
which using many quality tools to identify problem and improves the process. The data being analysed
by using statistical method and graph. As conclusion, the average number of accident decrease from
7.33 to 7.25 and the trend analysis shows decline graph compared to before. Based on the hypothesis
testing, using the p-value, it was found the shift pattern, safety culture (unsafe act unsafe condition
report submission), accidents location, type of activity and contractors have significance impact to
number of accident. Meanwhile, number of tonnage handled (productivity) and number of man-hour
does not have significance impact to the number of accident. It was also found that there is no
significance between numbers of accident happen at night shift, morning shift or afternoon shift. It can
be concluded that, the six sigma approach are suitable method to analyse accident and can be a
significance approach in determining the root cause of accident in the company.
Climate change influences over years clearly can affect a catchment area in terms of
quantity and quality of water. High annual rainfall in Malaysia does not solve water
scarcity problems during the El Nino phenomenon and can cause severe flooding
during La Nina. A simulation from year 1980 to 2006 has been done at Sg. Ketil
streamflow station at Kuala Pegang, Kedah in the North region of Malaysia according
to availability of data. The monthly streamflow later has been calibrated and validated
using SWAT-CUP. Water level data was obtained from an inventory water level station
recorded at the station. Land-use, soil type and slope are taken account to produce a
number of hydrologic response units (HRU). This study used developed gridded daily
hydrometeorological data set for Peninsular from 1980-2006using interpolation
technique. The results shown that the calibrated model is able to simulate the flow for
the river basin successfully with the R2
= 0.65 and NSE=0.52 and validated value of
R
2=0.5 and NSE=0.43. A recommendation is purposed to simulate the catchment using
hydrometeorological data set in the stations located in the area to compare the results
for further study.
Scheduling is one other method in productivity improvement. Scheduling occurs at the
operation level of production planning and control system. Scheduling is important because it can
optimize resource allocation and minimize waste. Simulation analysis can be used to evaluate the
scheduling technique in order to determine the best alternatives. A case study company, Olilys Sdn.
Bhd. Did are facing with the unsystematic scheduling methods for the job orders received from
customers. The problem became worst during peak period (high demand) where the company unable
to fulfil the customer orders. The objective of this project is to study the existing scheduling technique
and find related problem, and propose an improvement in production scheduling system. In this project,
there are five scheduling techniques proposed, which are First Come First Serve (FCFS), Shortest
Processing Time (SPT), Longest Processing Time (LPT), Priority Rules by product sequences: By Part1
and By Part 2, and Earliest Due Date (EDD). The simulation modelling and experimentation being
done by using WITNESS simulation software. Through the experimentation analysis, the best
scheduling technique was selected and suggested to the company
Electromagnetic pulse (EMP) is a sudden burst of wide-band, high-intensity electromagnetic radiation. EMP also called as a transient electromagnetic disturbance, a short burst of electromagnetic energy. Effect of EMP to automobile is classify as medium threats to vehicle attacks where EMP aims at damaging electronic devices such as on board sensors and processors, CPU which found in almost all models from 1990’s and forward. This paper presents a MATLAB simulation of EMP generator by means of Switch Mode Power Supply, thus the electrical shielding can be studied further. Theoretically, EMP generator is developed by implementing energy storage circuit and discharge control circuit. Sending a rapidly changing electrical current through a loop will create an electromagnetic field in the form of a pulse. The results show an increase in pulse voltage from 12 VDC to 758 VDC with a current of 1500 A. A MATLAB model on the coverage area affected by EMP pulse will be developed in the next phase of the research.
This study seeks to investigate small and medium-sized enterprise Human Resource (HR) practitioners’ knowledge pertaining to legislated employment rights at the workplace as laid down by the Employment Act (EA) 1955. The EA provides a variety of individual employment rights covering protections of wages, statutory right to the general standard of working time, statutory right to rest day, public holidays, annual leave and sick leave, statutory right to employment security as well as female employee’s statutory right to paid maternity leave. The study also aims to determine whether HR practitioners’ level of knowledge concerning legislated employment rights differed significantly between age groups, years of experience, level of education and size of company. It also examined the nature of the relationship between the HR practitioners’ level of basic knowledge concerning legislated employment rights and their level of concern in making legally sound decisions in their administrative practice. In addition, it identified whether the HR practitioners’ level of basic knowledge pertaining to legislated employment rights correlate significantly with the size of the company where they are employed.
The present study investigated the correlation between occupational stress and job
satisfaction of police officers in Punjab, Pakistan. The sample consisted of 300 senior police
officers. The sample was further divided on the basis of gender differences. The sample was
selected from Punjab, Pakistan. Survey research method was used for data collection. Police
Stress Questionnaire (PSQ) was used for measuring the occupational stress and job satisfaction
was measured by Job Satisfaction Survey (JSS) scale. Results found that there is a negative
correlation between occupational stress and job satisfaction. It was also found that female
police officers have high occupational stress as compared to male police officers.
This paper examines the concept of reform in terms of religious, political and social
aspects in PB Shelley’s literary works. Selections from Shelley’s poetry, prose, essay
and drama are reconsidered to show the concept of reform in his works. This paper
seeks to unravel Shelley’s skeptic revolutionary thoughts that were always
misunderstood by the critics of his time. Shelley as a poet perpetuated his life as a
reformer, yet his concept of reform was neglected and often downplayed because of
his idealistic view of the world. However, the significance of Shelley's concept of reform
merits, more reverence, or, at least, more critical consideration than any of the Great
Romantics.
In this study, compatibilizing effects of caprolactam-maleic anhydride (CL-MAH) and
polyethylene-grafted-maleic anhydride (PE-g-MAH) with different blend compositions on polymer
blends of recycled high density polyethylene (RHDPE) and ethylene vinyl acetate (EVA) blends were
investigated by tensile properties and swelling behavior. The use of CL-MAH improved the
compatibility of RHDPE80/EVA20 blend composition, and tensile properties of the resultant blend
compared well with those of RHDPE/EVA blends. Addition of PE-g-MAH improved the tensile
properties of RHDPE/EVA/PE-g-MAH blends than RHDPE/EVA blends without compatibilizer. The
scanning electron microscopy (SEM) morphologies of fracture surface for RHDPE/EVA blends with
presence of compatibilizers showing better incorporation of two different phases of polymer matrix.
Lack of parking space has become major contributing factor to traffic congestion
which may affect the environmental condition due to incalculable amounts of wasted
fuel and carbon emission. Congestion and parking are interrelated as looking for
parking space may create additional delay and impair local circulation. The proposed
automatic parking system which embedded with radio frequency identification (RFID)
and internet of things (IoTs) module will introduce a monitoring platform for the
parking space. This intelligent parking system makes it possible for the drivers to
obtain information beforehand through their mobile hand phone application or any
display available. This paper describes the mechanical design of automatic indoor
parking space with the advancement of sensor networks application known as RFID.
The design criterias were studied to develop a parking prototype which dealing with
number of degree of freedom as well as movement mechanism. The result presented
at the end of this paper was evaluated from the engineering analysis using the
developed parking prototype to meet system performance as well as design safety
factor.
With the rapid evolution of smart devices, ease of availability and accessibility of Internet
application services, the demand of user's level of satisfaction are constantly growing. This creates
challenges when mobile users in large quantity gather at confine places creating a scenario of highdensity
wireless network environment (HDWN). Guaranteeing high quality of services (QoS) without
proper understanding of user’s expectations and their Quality of Experience (QoE) may lead to over
provisioning of resources. This poses different challenges to network service providers. Moreover,
limited studies have been found relating to QoE in dense network. The objective of this paper is to
develop mapping mechanism that maps QoS parameters onto QoE metrics in HDWN. This paper
proposes fuzzy-genetic algorithm to map QoS-QoE based on the critical comparative analysis of
different mechanisms. Preliminary analysis had been done based on mathematical model to establish
the correlation between QoS parameters (delay and jitter) and QoE metrics (satisfaction) to determine
the maximum and minimum impairment threshold. Further, the correlation between QoS-QoE had been
evaluated with varying traffic load to determine the traffic load impact on QoE. Also the load threshold
was found, that would help the network providers to take proper measure to maintain user’s satisfaction
as the maximum threshold limit is reached.
The lack of understanding of Islamic principles in the design of public spaces has led to
the weakness of the function, aesthetic value and the identity of urban places. The study
seeks to identify the characteristics and elements of the Islamic urban space in
Putrajaya base on publics and expert perception and preference. A questionnaire
survey was conducted with approximately 500 civilians to analyse the public perception
of Putra Square and Astaka Moroco. A photo base interview was carried out with
approximately 100 professionals in the built environment field to evaluate the quality
of Astaka Moroco in comparison to Islamic gardens in the Middle East based on their
perception. The results indicate that the style of the Dataran Putra is the most preferred
by the public compared to the Astaka Morocco. The professionals inform that Astaka
Morocco is not comparable to the quality of Islamic gardens in the Middle East either
in terms of function or aesthetic value due to the lack of understanding of the Islamic gardens elements and principles. In addition, the public liked the Islamic garden style
that reflects the local identity and the functions as public spaces instead of just as an
exhibit or a model. The findings can be a good guide in designing the Islamic public
spaces which are favoured by the public.
This study was conducted to establish callus cultures from leaf, stem and root explants of
Physalis minima using different combinations of 2,4-D and kinetin. Callus growth and anti-cancer
compound, physalin B production were further enhanced by optimising the cell explants and media
compositions such as basal media, salts concentration, carbon sources and plant growth regulators.
The results indicated that callus cultures derived from leaf, stem and root explants were best initiated
using a combination of 9.0 µM 2,4-D and 4.5 µM kinetin. Callus growth and synthesis of physalin B
were peaked at the late exponential growth phase over 25 d of culture. Callus growth did not vary
between explants, but physalin B was observed higher in leaf (0.78 mg g-1 dry wt.), followed by root
(0.71 mg g-1 dry wt.) and stem (0.64 mg g-1 dry wt.). MS basal medium was found superior to B5, SH
and WH basal media in supporting growth and physalin B production. Further tests on the media
compositions obtained a half strength of MS salts (½MS), 2.5% (w/v) sucrose and 9.0:4.5 µM of 2,4-
D:kinetin combination, which were the preferred salts strength, carbon sources and plant growth
regulators for optimum growth (0.23 g dry wt.) and physalin B production (1.75 mg g-1 dry wt.) of
callus cultures derived from leaf.
This article describes the approach towards a sensitivity study of wind flow and pollutant
dispersion in an idealized street canyon with tree plantings under thermal atmospheric conditions
using computational fluid dynamics (CFD). First, validation studies were performed to determine the
best turbulence model for the simulation of wind flow under thermal atmospheric conditions against
the previous experimental wind tunnel data. The results of the numerical simulation indicate that
large eddy simulation (LES) can accurately predict the wind flow structure at different thermal
intensities and different locations of heated wall. Finally, detailed descriptions of future research are
presented at the end of this article.
One of the prime inspirations for this work emerge from the need to deal with our
common assets (the Land). To build up a formal approach that can be utilized to
address the issues emerges from a mind boggling circumstance in land
administration. The capacity to track the progressions as it is connected to land
everywhere throughout the year. A considerable lot of the land exchanges are as yet
in light of 2D ideal models that have frustrated fast advancement in thickly urban
condition. The consideration of 3D enhanced the functionalities of different models.
Be that as it may, the dynamic idea of the land has an imperative part in the
advancement of the land administration framework. One of the significant reason the
expansion in intricacy in land utilize required that Land Administration Domain Model
(LADM) concept in land administration has an enhanced limit is to deal with the
current 2D and 3D. The need to talk about time dimension emerges from the way
that individuals relationship to the land has an exceptionally powerful nature, all the
LADM packages has time (Temporal) components. LADM completely bolster forming
(historical information) as all classes inherit from VersionObject, and all LA_RRR
object have the quality TimeSpace. 2D/3D space and time incorporation is not
profoundly integrated into a 3D/4D spatiotemporal portrayal. The preparatory test
case in this study affirmed the conceivable outcomes of having a move or
development (with time) of characteristic limits from their underlying positions. Thus,
the dynamic idea of the land in connection to man, the benefits of this model to the
land proprietors, land merchants, and the administration can't be over stressed. This
study tries to clarify the current 2D/3D approach and broke down preparatory
requirements for 4D with a specific end goal to see the estimation of the approach.
The primary future research exertion focuses on melding on the most proficient
method to coordinate the model completely into Country profile in the study area.
In this study, fatigue failures of bio-composite materials were predicted due to
manufacturing defects. Kenaf bast fibres were used to fabricate a bio-composite material with epoxy as
a binding material. The bio-composites were manufactured by using a hand lay-up process. The defects
in the Kenaf/epoxy bio-composite were determined by a non-destructive technique using Infrared
thermal imager. Besides, the thermography analyses were verified via optical microscope and scanning
electron microscope (SEM) investigations. Determinations of fatigue, as well as damage had been
predicted, and it was found that the damage could be fixed with the predicted results.
Moringa oleifera is a plant with various benefits to mankind from its root until leaves.
From food to biofuel applications, all parts are useful for daily uses. In this research, the pod husk
was examined to determine the possibility of producing ethanol. The pod husks were dried and used in
two forms; one is grinded into powder, and the other is cut within 5 x 5 x 2 mm. About 10 grams of
Moringa oleifera pod husk was put into a conical flask and added with distilled water up to 250 mL.
The pre-treatment was made by adding an alkaline solution, NaOH, where the pH of the sample was
adjusted to (4.5, 5.0, and 5.5) using H2SO4. The samples were autoclaved at a temperature of 120°C
for 2 hours before the samples were cooled to room temperature (25+/-2oC). Baker’s yeast
(Saccharomyces cerevisiae) was prepared with different concentrations (1g, 5g, and 10g) and added
to the samples for fermentation process that took place in the incubator shaker at a temperature of
36°C, for a period of 72 hours. The bioethanol concentration was measured using High Performance
Liquid Chromatography (HPLC) with a refractive index detector and REZEX ROA-Organic Acid
HPLC Column using 0.05 N H2SO4 as the mobile phase. The bioethanol produced from Moringa
oleifera pod husk was 8.400 g/L using 1g/L yeast, and the fermentation took place at pH 4.5 for the
sample size of 5 x 5 x 2 mm. The results showed that Moringa oleifera pod husk can be introduced as
a new material for bioethanol production in Malaysia and other tropical countries where this tree is
available
This study is intended to focus on the aspects of police competency in implementing
Emergency Response Plan in National Stadium Bukit Jalil consequence to the current
rising trend of spectator’s violence. This new emerging trend has also given birth to
“Ultras Malaya” which is known for their fanaticism and have often cross the boundary
of safety and security. The methodology adopted is through the distribution of a set of
questionnaire to 150 respondents in Cheras Police District. Questionnaire were divided
into four broad categories. Except for demography, knowledge, skills and attitude were
measured by using Likert Scale. Knowledge was mainly to gauge the understanding of
the personnel on emergency, emergency preparedness and emergency response plan.
Skills was to gauge the proficiency to undertake tasks related to emergency response
in football stadiums. Attitude was to highlight the perception of the personnel towards
training and drill needs, the review of the emergency response plan and the capabilities
and the interoperability amongst authorities. Data was analyzed by the descriptive
mode such as frequency, mean and percentage. Findings revealed a performance gap
whereby majority of officers deployed at national Stadium lacked the necessary
experience and exposure to handle such volatile crowd and in a closed area. Hence the
understanding that RMP should be the key player in stadium safety should be revisited.
The study concluded by recommending a changing face in football policing through
increasing the absence of uniformed police, Stadium Management to be responsible
for the safety of spectators and appointment of stewards to fill the void created by
police withdrawal.
Rural communities in sub Saharan Africa have spent considerable time and energy in
their quest for obtaining cooking requirements. The utilization of solar energy for cooking is not a
widespread practice despite the fact that African countries are abundant in solar resources. A solar
cooker uses the freely, environmentally friendly, healthy and renewable solar energy resource as its
energy source, thus indicating its economical and sustainability advantages. This paper demonstrates
the possibility of using solar energy as an alternative to the traditional system of cooking local
foodstuffs within the rural communities of North-East Nigeria. The cooker was designed and fitted
with a black pot and an automatic tracking mechanism that can track the sun at 10° per hour,
following the sun movement for use in tropical dry climates. Parboiled rice of 1kg each was cooked
completely in 75 minutes at an average solar beam radiation of 623W/m2
after attaining maximum
temperature of 368K under clear weather condition. Whereas 1kg of beans and 1.1kg of yam were
cooked in 90 minutes at an average solar beam radiation of 536.5W/m2
and 430.1 W/m2
respectively.
The highest temperature reached for this test was 368K. The results indicated that a parabolic solar
cooker can easily cook these varieties of Nigerian local dishes within the range of 75 to 90 minutes
under the clear weather condition of Bauchi, north–east of Nigeria.
Cryptographic algorithm has become one of the most important aspects in hardware
implementation of embedded security system design. Message Digest (MD) is one of the cryptographic
algorithms that can be used in any security design application. Nowadays, designing the high speed,
low power, and small area implementation of cryptographic algorithms on reconfigurable hardware is
one of the critical subjects for hardware application. The purpose of this paper had been to analyse the
structure of MD5 hash function for high performance implementation in order to obtain small area
implementation, as well as to increase the speed of the design on FPGA. In this paper, the frequency
maximum for MD5 design with both grey and binary signal encoding is discussed. The results retrieved
from the analysis showed that the differing results were caused by the switching bit of the signal input.
Besides, the frequency maximum of MD5 that employed binary signal encoding provided the highest
frequency maximum with smaller area implementation. By using grey signal encoding, the frequency
maximum was almost similar to the MD5 binary signal encoding, but it suffered larger area
implementation. On top of that, this research focused on timing and area implementation of the design,
where TimeQuest timing analyser was applied to optimize the output of the desig
Honeycomb with good mechanical properties and low density are the top priorities in
material selection. Therefore, the facesheet thickness is a factor that contributes to it
as it made up most of the weight in the structure. Appropriate thickness can optimize
the mechanical performance. However, the sandwich composite may associate to high
density if the facesheet is of high thickness yet deteriorate the mechanical properties
as an overall. As the facesheet is attached to the sandwich structure via matrix, the
peeling properties for various facesheet thickness is investigated. The facesheet
thickness in terms of one to five layers are glued to the rubber wood core. The
structures are tested for its peeling strength under vertical 90° test according to the
ASTM standard. The optimal number of facesheet with good peeling strength is
discussed
