Abstract
Leading and managing form the framework for skills and abilities that are necessary for an individual to drive team success. Occupational safety and health (OSH) Leadership modeled the organisational commitment in OSH and for the commitment to growth and sustained, it requires management support for employees OSH engagement. Both of the leadership and management support are addressed in the safety and health policy as stipulated in the Section 16 of Occupational Safety and Health Act 1994 to provide assurance on the OSH compliance as well as providing opportunity for employer to establish decent work through freedom from injury and ill health and provision of safe and healthy workplaces. The aim of this paper is to determine the influence of OSH management support in the relationship between OSH leadership and Safety Performance in Malaysian Industries in the context of organisational culture model. 300 responses who were OSH practitioners were collected from twelve different industries in Malaysia. Data were analysed using SPSS and AMOS. Results showed that having a leadership alone is not sufficient to improve OSH performance, it needs the mediation effect of OSH management support on OSH performances.

Abstract
Medical image registration is one of the processes involved in medical image analysis. During the process, an image will be computed and transform it for mapping the reference image to the target image to analyze the similarity merits as to help in diagnosis the situation in the medical field. However, the accuracy of the image registration is in question, might be improved if we can make use some optimization during the image registration process. In this research, we propose an enhancement of image registration algorithms based on monomodal registration by incorporating Cuckoo Search (CS) method for Lévy flight generation while simultaneously modifying and optimizing it to work on MRI image scanners, specifically to detect brain cancer. The performance of the proposed monomodal registration with CS algorithm was compared with basic traditional monomodal registration. The experimental results were validated by measuring the Normalized Mutual Information (NMI) and CPU run-time for all cases investigated. Our results show that the proposed monomodal registration with CS algorithm achieved the best 2% improved in NMI results and 42% reduced in CPU run-time. The method evolved to be more promising and computationally efficient for medical image registration.

Abstract
Wheelchair are designed to enhance a patient’s personal mobility. It should help users to engage as much as possible in events. Therefore, rather than having a negative impact on its health or safety, the consumer should be able to live more active lives. Researchers have constantly worked to provide the patient with the best tool. At the time, patients had the option to use a wheelchair only, but now exoskeletons were introduced and proved as planned to have been successful. However, the use of wheelchair have never been brought down, in fact, the wheelchair that we all known are evolving into something fresh and new due to the effort of researchers applying new technology. Since a new idea for wheelchairs has been proposed, we conducted a systematic mapping study (SMS) on features introduced by researchers on wheelchairs. We identified 41 papers coming from conferences, symposium, workshops and journals. A total of 13 features exist in wheelchairs are identified. We present a qualitative analysis of the wheelchair, an overview on features for wheelchairs.

Abstract
To some, the retail banking market is considered an oligopoly. This is not healthy for a country’s economy and its people because it is important for competition to thrive in the banking industry. Any form of market failure or anti-competitive behaviour affects productive efficiency, consumer welfare and economic growth. With the introduction of the Base Rate (BR) to replace the Base Lending Rate (BLR), Bank Negara Malaysia (BNM) seeks to inject transparency into the mortgage framework. Under this system, banks will have to disclose their margins and are not allowed to loan below the BR just to attract customers and boost loan growth. This new framework will allow customers to make better financial decisions whilst having little impact on borrowers. Even though this only applies to personal home loans, it still poses a challenge to competing banks. Those with a seemingly strong niche in consumer financing will be able to offer more attractive and competitive BR leading to better Effective Lending Rates (ELR). This paper proposes using Game Theory (GT) as a method to predict probable outcomes in strategic interactions for BR revision. Monte Carlo Simulation (MCS) will then provide a means of weighing the probabilities of the contributing factors. With the ability to anticipate the competition’s next moves in a quantifiable manner, strategists will be better prepared in understanding and navigating the complex banking system.

Published: July 2020

Abstract
The quality of cutting depends most on the cutting tool condition. Towards having a good quality finish, cutting tolerance becomes a major concern, especially when machining at micro-scale where highly precise cutting is desired. This research investigates the size-effect during the micro-milling of Ti-6Al-4V under dry condition where the observations were made on cutting edge rounding (CER) and workpiece surface roughness. The result showed that the lower the feed rate, the greater rounding on the cutting edges were observed. Similar trend in result was obtained when measuring the surface roughness. The best feed rate for both observations was at 60 mm/min, where this setting has brought the mechanism to shearing, as the ratio between undeformed chip thickness and cutting edge radius started at 1.

Published: July 2020

Abstract
Development of Hydro Generation Concept Trainer was created to show the basic concept of Hydro Power Plant which is a part of the Power System curriculum taught in Malaysian polytechnics. This trainer was designed to model hydroelectric power plant which converts energy derived from flowing water into electricity. This project was made based on Bill Kelsey’s hydro concept whereby fast flowing water is used to spin a turbine which will then spin a metal shaft forming the equivalent of an electrical generator that produce electricity. The electromagnet in the generator will generate the electrical voltage and current in the stationary coils of wire inside them. This trainer uses only direct current (DC) which differs from most hydro generation trainers using alternating current (AC). Moreover, this low cost trainer successfully utilizes a battery as a capacitor bank, replacing the costly capacitor bank used to store electricity in an actual hydro power plant.

Abstract
High-speed machining (HSM) in milling has known is one of the technologies in rapid tooling and manufacturing applications. The cutting mechanism, spindle speed and feed rate are not the same for HSM compared to traditional machining. Coated carbide cutting tools are widely used in high speed and cutting temperature situations. It is more efficient and providing a lower surface roughness in HSM. Throughout these days, the demand of standard surface roughness is very high aligned to achieve quality in product. This paper shows an optimization method of machining parameters in milling process for high speed machining of glass fibre reinforce polymer (GFRP) using coated carbide cutting tool to achieve better surface roughness. Taguchi Method are used and it is the best method to optimize a parameter, where a response variable can be determined. Standard orthogonal array of L9 (32) was applied in this research using signal to noise (S/N) ratio response analysis from optimization process results and analysis of variance (ANOVA) to identify the most significant parameters affecting surface roughness. The common machining parameters are significantly affecting surface roughness are spindle speed and feed rate. Then, conformation tests were executed to analyse the improvement of the optimization. As result, the feed rate parameter are significant for affecting the surface roughness and 90.3 % improvement on the surface roughness performance of milling process for glass fibre reinforce polymer (GFRP).

Abstract
Emission of hazardous SO2 into the atmosphere due to the burning of fossil fuels in various industries is detrimental not only to the environment but also to human beings. Various mitigation techniques have been implemented to overcome this problem, with flue gas desulfurization (FGD) method being the most commonly used. Dry FGD does not typically perform as good as wet method and requires new type of sorbent to be tested. Mesoporous silica (MS), a sorbent with porosity in the range of 2-50 nm is considered as attractive alternative due to its high specific surface area, ordered pore structures and wide array of morphologies. Due to relatively weak interaction between MS and SO2 adsorbate during dry FGD process, additives are introduced to overcome this problem. These MS are modified with basic additives which are deemed more favorable for SO2 adsorption. Metal and amine-based additives are commonly employed where the latter are reported to obtain higher adsorption capacity. Increasing additive loading is beneficial up to an optimal value depending on the types of additives.
