Power reliability is one of the biggest concerns for people living off-grid. Current practice in off-grid solar house tends to either oversize solar power system or oversize the backup generator to ensure available electricity at all times, which often leads to a high system capital cost. Research has shown that right-sizing is essential to achieve a more efficient system with reduced energy co...

Thus, some dissertation copies are in typewriter face, while others may ...

Most Wave Energy Converters (WECs) produce highly distorted power due to the reciprocal motion induced by ocean waves. Some WEC systems have integrated energy storage that overcomes this limitation, but add significant expenses to an already costly system. As an alternative approach, this article investigates the direct export option that relies on aggregate smoothing among several WECs. By opt...

OBJECTIVE To investigate the response of very small coronary arteries to stent deployment and balloon angioplasty. SETTING Normal porcine coronary arteries. METHODS 24 pigs underwent intervention to two main coronary arteries, in segments 2.0 mm in diameter, with balloons whose diameter was 2.5 mm at standard pressure. Twelve arteries received a BiodivYsio small vessel (SV) stent; 12 an NIR...
