Isbn: 9780141986364 - exercised: the science of physical activity, rest and health (48 risultati)

Paperback. Condizione: Very Good. Lo scopo di questo libro quello di affrontare i temi principali di una serie di studi sperimentali e teorici sul controllo del generatore a induzione a doppia alimentazione nelle turbine eoliche. Il sistema di turbine eoliche (wt) un sistema moderno ed efficiente che genera diversi megawatt da una singola unit turbina. Il problema del sistema di turbine eoliche la fluttuazione del vento e l'irregolarit della velocit . Pertanto, il presente lavoro fornisce un metodo per controllare la velocit della turbina eolica ad asse orizzontale e quindi controllare la generazione. In questo lavoro, i modelli di simulazione della turbina eolica ad asse orizzontale (HAWT) a velocit variabile con generatore a induzione a doppia alimentazione (DFIG) sono costruiti utilizzando il software matlab/simulink (2016b) e i convertitori elettronici di potenza sono utilizzati per controllare la velocit della turbina e la generazione a un valore costante. Vengono applicati due metodi di controllo, il controllo orientato al campo (FOC) con controllori proporzionali-integrali (PI) e la modulazione di larghezza di impulso vettoriale spaziale (SVPWM), per controllare elettricamente la velocit della turbina eolica e mantenere la frequenza e il sistema di generazione.…

Paperback. Condizione: Very Good. 'Endlessly fascinating and full of surprises. Easily one of my books of the year' BILL BRYSONThe myth-busting science behind our modern attitudes to exercise: what our bodies really need, why it matters, and its effects on health and wellbeing. In industrialized nations, our sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases like diabetes. A key remedy, we are told, is exercise - voluntary physical activity for the sake of health. However, most of us struggle to stay fit, and our attitudes to exercise are plagued by misconceptions, finger-pointing and anxiety.But, as Daniel Lieberman shows in Exercised, the first book of its kind by a leading scientific expert, we never evolved to exercise. We are hardwired for moderate exertion throughout each day, not triathlons or treadmills. Drawing on over a decade of high-level scientific research and eye-opening insights from evolutionary biology and anthropology, Lieberman explains precisely how exercise can promote health; debunks persistent myths about sitting, speed, strength and endurance; and points the way towards more enjoyable and physically active living in the modern world.'Myth-busting, illuminating, brilliant - Lieberman will completely change the way you think about your body' Professor ALICE ROBERTS, presenter of Our Incredible Human Journey. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged.…
