At the end of the study, the details of buyer requirements are plotted into House of Quality, where it is believed to improve the quality of future bungalow house development in Melaka.
Production Sharing Contract (PSC) is one of the petroleum agreements mode that
are being utilized in many parts of the world in enabling exploration, development
and production of the petroleum resources at the respective locations. It was first
introduced in Indonesia in 1966, and followed by Malaysia, Vietnam, Thailand, and
Brunei. One of interesting aspects of PSC management is the operatorship
transferhandling when a PSC is nearing its expiry. When the time come, the
current PSC contractor as operator has the option to relinquish it to the host
authority to be handed over to other operator, farm it out to the other PSC
contractor to reduce the risk exposure or continue operating under a new PSC
terms. The most challenging will be to relinquish the operatorship to another
operator whereby several complexities will need to be adequately addressed to
ensure benefit preservation to the host authority, incoming operator and
outgoing operator. Therefore there is a need to adhere to key factors or enablers
to administer the operatorship transfer exercise if it occurs in the near future. The
key enablers would be able to address the operatorship transfer exercise
effectively with the objective to alleviate complications to the host authority,
outgoing operator and incoming operator. With the emphasized in the PETRONAS
Procedure & Guideline for Upstream Activities together with three case studies,
this paper proposed several key enablers to be considered for a PSC successful
operatorship transfer which is human resources, data management, asset
reliability and integrity management, supply chain management and good
relationship between parties. With identified key factors, it is hoped that any PSC
operatorship transfer will be able to be managed smoothly and will ensure
benefits to all parties concerned.
Fibrous concrete composite (FCC) have been applied in numerous civil engineering
structures, such as pavements, dams, runway, hydraulic structures, aircraft parking,
and runway. The desire for their usage as being due to their unique properties
compared with other materials. The stability of fibres in cement concrete appears to
be good enough, but further long term tests are necessary to evaluate their durability
and performance under mechanical sustained load. This is owing to the dearth in
knowledge on the fibrous concrete particularly bio fibrous concrete composites (BFCC)
behaviour and response to compressive, flexural and uniaxial tensile sustained loads.
Therefore, an in-depth study into the creep performance of BFCC is necessitated to
understand the long term behaviour of this biodegradable and environmental friendly
construction product. This will avail the structural engineers and builders’ adequate
understanding and data for design construction purpose of this green concrete
product.
Urban Transit Network Design Problem (UTNDP) focuses on deriving useful set of
routes, manageable timetabling for each transit route and transit scheduling based on
available resources. UTNDP is commonly subdivided into Urban Transit Routing
Problem (UTRP) and Urban Transit Scheduling Problem (UTSP), respectively. There are
various approaches applied to solve the UTSP. The aim of this paper is to give a
comprehensive list of studies on UTSP that deals with metaheuristic approaches such
as Tabu Search, Simulated Annealing, Genetic Algorithm and their hybrid methods. This
review also addressed possible gaps of the approaches and the limitations of the
overall problem. It can be concluded that only some of the metaheuristic approaches
and sub-problems are highly studied in UTSP. This review will be useful for researchers
who are interested in expanding their knowledge and conduct research in UTSP using
metaheuristic approaches.
Historically, there is evidence to suggest that communities in the developing countries
are still using plant-based materials as one of the strategies for purifying drinking
water. In this review, the coagulant properties of Moringa oleifera seeds extract were
quantitatively evaluated toward suitable wastewater treatment and examining its
coagulation mechanism. The seeds are rich in bio-active components and also used as
a natural coagulant for effective water treatment. The seeds extract operates
predominantly by bridging coagulation mechanism and operates through charge
neutralization. This natural ingredient of an organic polymer is essential as it contains
acrylamide monomers that are harmless to human’s health and lesser expensive as
compared to conventional chemicals since they are available in most rural
communities. The application of this readily available natural product as part of pointof-use
in water treatment technology may offer a practical, cheap, appropriate and
sustainable solution for producing potable water in some developing nations.
This study was performed to review the experience of work-family conflict and work-family
enrichment with social support as the moderator. Work-family conflict or enrichment occurs when
behaviours, moods, stresses, and emotions from work bring bad or good effects into family. Social
support has been seen as an important factor to assist employees with their role at work and at home.
This will reduce work-family conflict among the employees and achieve positive level of inter-role
between work and family, which is work-family enrichment. The review provides evidence that social
support may be helpful in improving the quality of work-family life of employees.
The use of a sprinkler irrigation system is becoming more popular to reduce water
consumption and increase irrigation efficiency. Irrigation uniformity plays an important role in the
performance of the sprinkler irrigation system. The use of low operating pressure instead of high
operating pressure system offer many benefits including energy and water saving. An experimental
study was performed using two systems; a square 12x12 m system and a rectangular 10x12 m system
to investigate irrigation uniformity based on soil moisture content of the sprinkler irrigation system
under low operating pressure. In addition, irrigation uniformity was compared based on water
application and soil moisture content. In this study, different low operating pressures (62, 82, 102 and
122 KPa) were selected. Different nozzle diameters (4, 5, 6 and 7 mm) and different riser heights (0.5,
0.75, and 1.0 m) were also used. The soil moisture content uniformities of 10 min after irrigation are
more dependent on the initial soil moisture content uniformity than any other design factor. It is also
less influenced by water application uniformity.
A summary of research on image visualization in fluid flow is presented. The review
addresses the topics of method in image processing, the application of particle image velocimetry and
different sensor source of tomography. One of the greatest challenges in image visualization research
is the improvement of flow measurement for multiphase flow. As there a lot of prediction in studying
multiphase flow, the selection of image visualization method has to be chosen carefully. The important
part is the method to process the image which consists of parameters to be studied. The improvement
in image visualization method is important to further applied to other area of process.
– Today, the new valuation of sustainable materials in light of their ability to fulfill the
requirements of sustainable development has raised the bar. The economic growth will result in
increased material throughput as well as solid and hazardous waste generation. Understanding the
life-cycle of materials management and monitoring materials consumption trends will provide the
information in determination of how we can satisfy our materials needs at acceptable economic and
environmental costs to assist both regionally and globally. This paper reviews the challenges for
sustainable development from material aspect and the future prospect of the utilization of sustainable
materials in construction industry. Policy designs together with steering mechanisms are required to
facilitate and support further mainstream sustainability transitions. Besides the price system,
regulatory framework and technical information, human mindsets must work together to enable and
encourage life-cycle of materials management. Further research and development will not only provide
innovative solutions to existing problems but will in particular offer new opportunities through the
development of innovative materials to improve the quality of life.
High quality of product and service is always demanded by customers. Conversely, poor
quality of product and service will result with customer dissatisfaction. However, this linear
relationship is no longer accurate due to the complexity nature of customer needs. Non-linear
relationship should be considered for more accurate evaluation of customer needs. This paper
presents a concept of Kano model and Quality Function Deployment (QFD) integration to evaluate
the non-linearity of customer needs towards the quality of products or services. By a case study, the
developed Kano-QFD model is validated with the theory of Kano model and found to have well
agreement. Further application for product development is recommended for future research.
This review presents generally about Virtual Reality (VR) technologies in industrial
training. Virtual reality training is increasingly used for maintenance and operation,
assembly procedure, welding and operative construction training that allow the
workers to work on existing and new tasks in safe, and perceive on how an item takes
shape as it travels through the manufacturing system, which result more effective
training. For companies to spend the large amount of economic resources in training
people, thus VR systems for training may reduce in dealing with issues such as the high
economic costs of training for travel and living expenses for those who need to move
from work to training centers. An adaptive technology has been used for pilot training
and vehicle driver training that may improves accuracy of the procedure. VR training
could create a more effective and efficient learning even without the presence of a
trainer.
This review paper describes in general the use of VR as a training tool in manufacturing
technology like design, rapid prototyping, and manufacturing with some practical
examples where VR is used and its benefits in manufacturing industries which reduces
a lot of cost in the design stages to the finish stages. VR is the closest man can get to
reality as the names implies with the present capabilities. The technique enables
engineers and designers to move around and interact with the object in real time. This
review paper looks into some challenges of VR applications in manufacturing
industries.
