Title of Speech: Control of Kinetic Energy Recovery Systems for Hybrid Electric Vehicles 

Abstract: Hybrid Electric Vehicles (HEVs) are becoming increasingly popular as the world become more environmentally conscious. The primary advantage of hybrid electric vehicles is their extended travel range when compared to full electric vehicles. However, the efficiency of hybrid vehicles is limited by the ability of their small electrochemical batteries, intended only to store the energy recoverable from a typical braking cycle, to absorb large regenerative braking currents. Energy in excess of what the battery can safely absorb must be dissipated through the friction brakes of the vehicle. To address these problems, Kinetic Energy Recovery Systems (KERS) incorporates a mechanical flywheel energy storage system into HEVs to increase overall system efficiency, extend battery life, reduce the needed volume of batteries, and extend travel range. The work to be presented shows the design of a low-cost KERS system, using technology appropriate for consumer and commercial HEVs. A supervisory control system for directing the appropriate level of power to the vehicle, chemical batteries, or flywheel is described. A small demonstration vehicle using the KERS system as described was built and tested, and the results from the testing are presented.

Title of Speech: Development of specialized engineering equipment 

Abstract: Commercial deployment of research output is a very daunting issue faced by most researchers. The strategy to commercialize market ready prototypes should start with preserving the “crown jewels”, the technology that is the basic premise of the innovation or the essence of what has been proven. Without changing the proven functionality, the parts surrounding the core technology and supporting systems would be designed or redesigned for the best manufacturability, cost, quality, and time-to-market while being integrated into an optimal product architecture.
The Centre of Advanced Manufacturing and Material Processing (AMMP Centre), University Malaya has been involved in numerous commercialization of research outputs and industry related projects from its inception in 2002. Several successful projects is presented as case studies to show its engineering development phases from concept ideas, modelling, lab prototypes, industrial redesign, commercial packaging and testing, scale up production and final sale and support services.
The talk will present the developmental journeys of these projects, highlighting the various stages in the process, such as in design conceptualization, prototyping, testing and commercial packaging. The products highlighted are, a modular Computer Numerically Control (CNC) lathe machine designed for the educational and Small & Medium Enterprises (SME) sectors, a specialized apparatus for the thermal testing of dental materials, an Minimum Quantity Lubrication (MQL) system for nano-lubrication during metal cutting and a powder Physical Vapour Deposition (PVD), a novel apparatus for the deposition of thin films from elemental powders.  

Biography: Professor Ir Dr Mohd Hamdi bin Abd Shukor received his B.Eng. (Mechanical), with Honours from Imperial College London and his M.Sc. In Advanced Manufacturing Technology & System Management from University of Manchester Institute of Science & Technology (UMIST). His Doctoral study was in the field of thin film coating for biomedical applications for which he was conferred Dr. Eng by Kyoto University. He is a Fellow of the Institution of Mechanical Engineering, UK, and a professional engineer registered with the Board of Engineers Malaysia. Prof Hamdi has devoted his career in nurturing research and innovation and has mentored over 70 PhD students, particularly in the field of machining, materials processing and biomaterials. He has authored more than 160 ISI journals and h-index of 26. He is also a director and founder of the Centre of Advanced Manufacturing & Materials Processing (AMMP Centre), in which has grown from modest-size team of researchers and engineers to an interdisciplinary research hub. Prof Hamdi has obtained recognition from various international and local organizations.

Title of Speech: Thermoelectric generators: Design considerations from molecules to devices  

Abstract: Thermoelectricity allows direct conversion of a thermal gradient into electricity. A good thermoelectric generator requires a system which has materials with good electrical conductivity, high Seebeck coefficient (ratio of voltage generated per degree Kelvin), and low thermal conductivity. This paper will illustrate design strategies which will optimize the performance of thermoelectric generator, from the materials and device viewpoint. Case studies from the thermoelectrochemical (TEC) generator, an important subset of thermoelectricity, will be used to illustrate these optimization strategies. The thermoelectrochemical (TEC) effect allows the transformation of thermal energy into electricity by an electrochemical redox reaction of electrolytes at the electrodes of the TEC generator. At the materials level, the use of spin crossover metal complexes (SCO) have been shown to produce high Seebeck coefficients. The molecular properties of these SCO complexes will be elaborated in order to demonstrate a direct correlation between molecular structure and TEC performance. On the device level, the performance of a TEC generator has been shown to be significantly enhanced by the insertion of a composite (PAN/PVDF) polymer separator into the TEC generator. This allows simultaneous allowance of ionic transport across the separator, yet enables the thermal attenuation across the TEC to be improved. Aspects of design for the composite separator will be discussed, including the device architecture, membrane fabrication processes, and membrane composition. Such strategies have significantly succeeded in improving the power generation capabilities of the TEC generator. Potential applications of this novel TEC generator architecture include harvesting of waste heat into useful electricity from low grade domestic waste heat, body heat and solar heat.
