This paper examines how flexible cellular system architectures and small pulley efficient spectrum management techniques can be used to play a key role in accommodating the exponentially increasing demand for mobile data capacity in the near future.The efficiency of the use of radio spectrum for wireless communications can be dramatically increased
This paper analyzes a Digital Signal Processor (DSP) based One Cycle Control (OCC) strategy for a Power Factor Corrector (PFC) rectifier with Common-mode Voltage (CMV) immunity.It is proposed a strategy that utilizes an Pain Relief emulated-resistance-controller in closed-loop configuration to set the dc-link voltage to achieve unity power factor (
The Arctic is experiencing dramatic changes including increases in precipitation, glacial melt, and permafrost thaw, resulting in increasing freshwater runoff to coastal waters.During the melt season, terrestrial runoff delivers carbon- and nutrient-rich freshwater to Arctic coastal waters, with unknown consequences for the microbial communities th
Introduction: Aorto-iliac Occlusive Disease (AIOD) involves the infra-renal aorta and the iliac arteries.Recent studies advocate endovascular management in TASC C and D lesions also.It involves balloon angioplasty with or without stent deployment.5 The aim of this retrospective study is to evaluate the results of endovascular balloon angioplasty an
