A Multiple-Input Dc-Dc Positive Buck-Boost Converter Topology

Abstract-
A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltage-current characteristics, while achieving low part number and bi-directional operational. Compare to previous multiple-input buck-boost converter, the proposed topology provides positive output voltage; it is capable of bi-directional operation; and it has the capability of operating in buck, boost, and buc ....etc

Abstract

We found that very thin carbon nanotube films, once fed by sound frequency electric currents, could emit loud sounds. This phenomenon
could be attributed to a thermoacoustic effect. The ultra small heat capacity per unit area of carbon nanotube thin films leads to a wide
frequency response range and a high sound pressure level. On the basis of this finding, we made practical ....etc

Abstract
Organic thin-film transistors OTFTs have received considerable attention recently because they can be fabricated at reduced temperature and potentially reduced cost compared to hydrogenated amorphous silicon thin-film transistors. Low fabrication temperature allows a wide range of substrate possibilities and makes OTFTs an attractive technology for many low-cost electronics applications, particularly those that require or may benefit from flexible polymeric substrates such as rf identification tags, smart cards ....etc

Abstract :
For the past ten years, organic materials have been extensively investigated as an electronic material for thin film transistor (TFT) devices. Organic materials offer strong promise in terms of properties, processing and cost effectiveness and they can be used in flat panel displays, imagers, smart cards, inventory tags and large area electronic applications. In this review, There is a particular need to develop air-stable n-channel (electron-conducting) organic semiconductors with performance comparable to that of p-channel (hole- ....etc

The extension matrix method is that at first, we find the distinguishing between the positive examples and negative examples. The extension matrix is used to represent those distinguishes, and then according to those distinguishes, the examples are induced so that the proper assertions are obtained. The extension matrix clearly reflects the distinguishing between positive examples and negative examples. It is easy to find the heuristic of a problem relying on it.

laser film is transmissive laser based play back medium. Working on the topology that laser has to shine through one side of the disc to a receiving sensor on the other side, where the beam of the laser would be interrupted by a spiral of small dots on the disc,which can then modulate the laser beam to represent the video and audio information, which was then interpreted by the receiving sensor receiving the beam on the other side Made of the ordinary photographic film, similar to the Select avision CED videodisc system, this wasnâ„¢t succe ....etc
