A Comparative Study of Electromagnetic Generator via Finite Element Element Analysis

Energy scavenging from ambient sources is an attractive alternative to batteries because of an almost unlimited lifetime and is environmentally safe

Performance characteristic of A cyclone gasifier for power generation.

A new technique of gasifying pulverized biomass fuel based on cyclonic motion concept is being developed for power generation.Sawdust has been used as a fuel for cyclone gasifier reactor to produced producer gases of typically 3 - 5 MJ/m3 . The work of this project involved both theoretical and experimental work to understand the operation as well as the performance and characteristics of a cyclone gasifier. Satu teknik baru untuk mengaskan bahanapi biojisim terhancur berasaskan kepada konsep pergerakan siklon telah dibangunkan untuk tujuam penjanaan kuasa. Habuk kayu telah digunakan sebagai bahanapi untuk reaktor pengas siklon bagi menghasilkan gas-gas terhasil secara tipikalnya 3-5 MJ/m3

High-isolation and low-loss RF MEMS shunt switches

This paper presents the design and simulation of a radio frequency (RF) microelectromechanical system (MEMS) shunt switch using a three-dimensional RF simulator, Em3ds10 (2008 version) software for the frequency range of 1-40 GHz. The shunt capacitive switch is electrostatic actuated and designed with a meander beam support to lower the pull-in voltage. Fast simulations of complex structures based on a method-of-moment approach allow for optimal design of MEMS switch. The switch has a simulated pull-in voltage of 2.5 V and the RF performances of insertion loss and isolation are less than -0.2 dB and -50 dB at 12 GHz, respectively

Performance of a biomass fuelled micro gas turbine power unit.

Alternative fuels have been considered as a priority in the research field, especially for the renewable energy, due to the issue of fossil fuel depletion. Pengkajian ini merupakan pembangunan dan pencirian sistem penjanaan udara panas skala kecil dengan biojisim, menggunakan turbin gas pembakaran luar berdasarkan sebuah "turbocharger" dan penghembus udara
