Electricity is one of the basic needs modern human life and already so integrated into everyday life. This understandable given coal's ample resources. Another factor that influences growth coal use plants are designed asa burden because price relatively cheaper. However, existence as fuel for power on decline not renewables. One applications renewable energy potential solar generation technolo...

Mallampati et al, proposed a grading system to anticipate difficult intubation, which considers visualization of faucial pillars, soft palate and base of uvula. 4 The upper lip bite test (ULBT) was proposed as a simple bed side technique by Khan et al, which involves the assessment of jaw subluxation and presence of buck teeth. 9 Savva et al, proposed sternomental distance (distance from the su...

Nobel citation makes clear, Buck and Axel not only and Molecular Pharmacology solved the mystery of the olfactory receptors but, in a University of California, San Francisco remarkable series of subsequent experiments, outlined San Francisco, California 94143 the basic organizational principles of the vertebrate ol2 Howard Hughes Medical Institute factory system. More generally, the discovery o...

In this digest, we will present a methodology that allow us to accommodate the conducted Electromagnetic Interference (EMI) generated by power factor correctors to international standards in the design step. EMI filter design considerations and EMI predictive procedures are presented. The predictive procedures are based in a family of curves that allows us to determine the conducted Electromagn...

An integrated buck converter that operates under low voltage environment with fast transient response is presented. The designed buck regulator employs derivative output ripple voltage for sensing current. It is targeted to be fabricated with 180nm UMC technology at 2MHz switching frequency. The response time is less than 2.2μ Sec. The regulator provides an output voltage of 1.8V against the ba...

This paper studies two kinds of simple switched dynamical systems with piecewise constant characteristics. The first one is based on the single buck converter whose periodic/chaotic dynamics are analyzed precisely using the piecewise linear phase map. The second one is based on a paralleled system of the buck converters for lower voltages with higher current capabilities. Referring to the resul...
