This paper discusses design, simulation and fabrication of new Micromechanical Thermal Converters (MTCs) based on GaAs developed for Gas sensors. GaAs MTCs seem to be very attractive for design of thermally based MEMS sensor devices. High thermal isolation of these devices can be done by implementing of free micromechanical hot plates which is designed as thin as possible. Metal oxide gas senso...

Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connect alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC grid connection of offshore wind farms.

A voltage current convertor is described having a quasi complementary class AB architecture that is particularly suited to implementation using discrete power MOSFETs. High-voltage mirror designs are presented, enabling the construction of sources with kilovolt compliance range, tens of watts of output power and greater than 100 kHz bandwidth. GΩ output impedance and distortion below 1% can be ...

This paper presents a complete statistical speech synthesizer for Myanmar which includes a syllable segmenter, text normalizer, grapheme-to-phoneme convertor, and an HMM-based speech synthesis engine. We believe this is the first such system for the Myanmar language. We performed a thorough human evaluation of the synthesizer relative to human and re-synthesized baselines. Our results show that...

Abstract In this work, a single degree of freedom resonant converter model is proposed and theoretical studies the are carried out. The suitable for waves with height up to 2 m period 5 seconds, such as on western coast Black Sea. It shown that at resonance its power increases significantly approaches values swell. high (up m) efficiency decreases, but remains relatively constant equal about ha...

To control the exhaust emissions from two stroke spark ignition engine, copper nano-particles coated on wire mesh at the junction of improved design as catalytic converter, AVL-422 gas analyzer was used for measurement and comparision for CO and unburnt hydrocarbon in the exhaust of the engine at various speeds and loads. In the present work, an improved design is proposed which is more suitabl...
