This paper presents a passivity-based control (PBC) design methodology for three-phase voltage source inverters (VSI) for uninterruptable power supply (UPS) systems where reduced harmonic distortions for the nonlinear load, reduced output voltage overshoot, and a restricted settling time are required.The output filter design and modification for ef

The use of computers for teaching and training has long been a controversial issue.Up to the 1980s, many educators who were keen to use computers to pass on knowledge developed various computer-based teaching and training materials, but most of these materials were capable only of delivering information in text with perhaps some essie gel couture i

Stroke is a leading cause of death and disability in both developed and developing countries.Limited information is available, in South Africa, on the epidemiological profile of stroke survivors requiring rehabilitation.A descriptive study was therefore undertaken to compile, amongst others the demographic and medical profile of stroke patients att

The embryonic development of salivary copyright tiki mug glands is a complex process that creates compact, highly organized secretory organs with functions essential for oral health.The development is an example of branching morphogenesis, recent research found to involve unexpectedly dynamic cell motility, and novel regulatory pathways.Numerous gr
