BACKGROUND Neurobehavioral impairment is a common complication of coronary bypass surgery. Cerebral microemboli during cardiopulmonary bypass (CPB) are a principal mechanism of cognitive injury. The aim of this work was to study the occurrence of cerebral embolism during CPB and to evaluate the effectiveness of evidence-based CPB circuit component and process changes on the exposure of the pati...
This work presents the complete implementation of a switched-capacitor double-sideband (DSB) to singlesideband (SSB) converter, using discrete components. In order to obtain efficient SSB modulation, a Hilbert Transformer has been used. The implementation of the Hilbert Transformer through recursive allpass transfer functions allows good dynamic range and low sensitivity to errors on implemente...
A new high-sensitive magnetic sensor which is referred to a symmetric response magnetoresistance (SRMR) proposed. This uses giant (GMR) elements have field response. An ac with frequency f applied the GMR in order modulate small detecting field. Due of MR element, carrier signal converted 2f and . By using full bridge circuit, where two pairs opposite phase field, components can be eliminated a...
Robust performance controller design for duty-cycle controlled series resonant converter (SRC) is proposed in this paper. The uncertainties of the converter are analyzed with load variation and power circuit components tolerances are taken into consideration. Additionally, a nominal performance (NP) controller is designed. Closed-loop system is simulated with Orcad and simulation results of r...
We construct a list of binary semantic relations that combines three lists recognized at different syntactic levels { multi-clause sentences, clauses, noun phrases. We identify relations that are the same at diierent levels and represent them in a level-independent way. We base our construction on the fact that many syntactic variants express the same idea, and a linguistic expression displayin...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
