Mathcad® - a 'learning enabler' in power electronics education
(Association of Engineering Education in South East Asia and the Pacific, 2007-02-14)
Advancement in technology and the resulting affects on curriculum content in an attempt to meet employer's needs requires careful consideration to avoid 'over pruning' essential basics. Developing delivery methodology that ...
Comparison on losses and flux distribution between two of 3 phase distribution transformer 1000kVA assembled with regular and irregular stack of transformer core lamination
(The Malaysian Research Group (MRG), 2007-12-06)
This paper describe the result of an investigation on the effect of different stack of core lamination in the two of 3 phase distribution transformer 1000kVA. The investigation involves the variation of power loss, building ...
Simplification of sun tracking mode to gain high concentration solar energy
(Science Publications, 2007)
Power conversion from solar thermal energy to electrical energy is still very cost-intensive. Serious effort has to be given in the development of the concentrator or heliostat structure expenditure which contributing the ...
Computer designed solar concentrator
(International Association of Science and Technology for Development (IASTED)/ACTA Press, 2007)
This paper discusses a computer designed optical concentrator, which is providing efficient solar energy transfer to a Stirling Engine. The receiver can make line focusing onto the absorber of Stirling engine located at ...
Tracking error analysis of a rotation-elevation mode heliostat
(Science Publications, 2007)
For the past few years, great efforts have been done in improving the tracking accuracy of a newly proposed rotation-elevation tracking mode heliostat. A special simulation program has been developed to systematically ...
Magnetic levitation (Design PID controller)
(Universiti Malaysia Perlis, 2007-04)
Magnetic levitation systems, based on electromagnetism, are characterized by open loop instability and non linear dynamics are described by highly nonlinear equations that suggest the need of stabilizing controllers which ...

Laporan ini bertujuan untuk memberikan seberapa maklumat tentang ciri-ciri aktiviti discas permukaan secara langsung dan aktiviti discas separa umumnya serta peringkat-peringkat proses merekabentuk alat pengesan terhadap ...
Comparison on losses and flux distribution between two 3-phase distribution transformers 1000kVA assembled with air gap and without air gap of transformer core lamination
(Institute of Electrical and Electronics Engineering (IEEE), 2007-12-06)
This paper describes the result of an investigation on the effect of air gap of core lamination in two 3-phase distribution transformers 1000kVA. The investigation involves the variation of power loss, building factor, the ...
Tracing generators' output in transmission open access
(Institute of Electrical and Electronics Engineering (IEEE), 2007-12)
Over the past few years, the electric power utility industries around the world have experienced a strong drive towards deregulation. Based on the experience of deregulation of the communication, natural gas and airline ...
