Abstract

The DELTA Smart House is going to have a large number of sensors and microelectronic devices located throughout the house. These devices will need a clean, reliable source of energy that wonâ„¢t need constant maintenance. The goal of this seminar is to discuss utilization of piezoelectric energy sources to provide power to certain applications in the house. Initially an energy scavenging floor that used piezoelectric transducers to harvest wasted energy in the foot strike of a human being. In consideration of the high cos ....etc

Ever since the invention of the wheel, mankind has been on a high in terms of the rapid strides made in technology. More so during the industrial revolution in the 19th century when extensive use of natural resources like natural gas, iron ore, coal etc. first started. The quest to sustain the rate of development has caused the depletion of these valuable natural resource. The exhaustible nature and possible environmental hazards of over-using these resources was not thought of then, especially the energy sources viz. fossil fuels, which take b ....etc

RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps and conventional lamps is that RF lamps operate without electrodes .the presence of electrodes in conventional florescent and High Intensity Discharge lamps has put many restrictions on lamp design and performance and is a major factor limiting lamp life.

Abstract

Systematic errors can occur in every chemical analysis independent of the method used. In general, the risk of systematic errors can be diminished by separation steps prior to the determination procedure. In sensor measurements systematic errors can be noticed only by anlysing real samples with a known concentration of the analyte with a great variety of matrices. The sources for such errors are manifold, although excellent reproducibility of the results is shown. The main reason for a systematically blased result in the field of ch ....etc

After years of research and development, radio frequency light sources are just now becoming a mainstream lighting option. RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps is that RF lamps operate without electrodes .There are three practical ways to energize RF light sources, though there are more ways to create RF plasmas. These three ways correspond to different types of inte ....etc
