The paper presents an integrated steering system design for bus drivers drowsy driving behaviour change. Busses involved in accidents due to drowsy driving is increasing nowadays and those accidents involved a lot of people due to the number of passengers it carries. In order to decrease the rate of accidents for bus driver due to drowsy driving, an integrated steering system that can change their driving behaviour is developed. The developed integrated steering system is then being validated through surveys conducted on drivers with valid driving licence. The survey results have shown that the integrated steering system is a feasible system to the drivers.

Current UTeMs fire fighting machine is developed to operate indoor only. It is not efficient when it is operating on rocky surfaces (outdoor) as it faces the problem of shock and vibration reduction. The track system of the machine cannot move smoothly because the rollers are fixed to the chassis. This paper describes the method of up-scaling and optimising the track system for the current fire fighting machine. The new track system concept is firstly developed by using Computer-Aided Design (CAD) and Computer Aided Engineering (CAE) software. Subsequently a prototype is built to validate the functionality of the new track system which is more efficient in absorbing the vibration and shock. Analysis and optimisation of the prototype is performed using CAD method with the CATIA V5 R16 software.

The methods in delivering engineering design have gone through evolvement where the effectiveness of conventional methods is decreasing. However, the importance of concurrent engineering design approach has tremendously increased due to the ever competitive world today. This is the reason why engineering designers are concern about the methods of delivering design and one of the recent interests is using interactive system to deliver design. In this paper, the construction of interactive system will be discussed followed by the experimental setup. Experiments will be conducted in the form of performing few selected tasks with the interactive system and comparison will be made with the conventional design approach. Comparison will be done by collecting feedback through questionnaires from the participants who are involved in the experiments. Feedback will be analysed to identify the feasibility of interactive concurrent engineering design system.

River pollution has been a global issue and the consequences of polluted rivers are significantly affecting human health and well-being. Meanwhile, water treatment plants (WTP) are often related to high energy cost. Nevertheless, there is an abundance of hydraulic energy stored in the flowing water, which can be converted into mechanical energy to operate the WTP. The focus of this paper is to describe an innovative method of harnessing buoyancy force to save the energy cost of commonly used motorized equipment in the conventional WTP. The benefit of this product is to create a green environment by utilizing a readily available hydraulic energy and restoring river water quality. This study has shown that a cost-saving water treatment plant operating based on buoyancy force is feasible. This product enables electricity cost to be minimized while treating river water at the same time.

Abstract. The development of new technology enables the comfort service becoming an important requirement in the air travel industry. Long haul air travel may cause different physiological and psychological discomfort of aircraft passenger. Most of the aircraft company treats the passenger comfort as a main priority for the user's acceptance of their airline. In order to improve the aircraft passenger body comfort during long haul air travel, an adaptive body support system was developed and embedded in the economy class aircraft seat. In this paper, we describe the development of adaptive body support system.
