爱护环境 低碳生活[绿色出行]——论杭州公共自行车对市民、游客出行的影响

在学院组织的暑期社会实践当中,我们以西湖风景区为例,对"杭州公共自行车对市民、游客出行的影响",通过发放问卷、采访有关单位负责人等形式,展开了深入调查,并得出以下结论。1杭州公共自行车对人们出行方式选择的影响杭州公共自行车从2008年5月诞生到现在,也不过只有三年多的时间,但已经对市民、游客的出行方式的选择产生了极     

Rigid sensor allocation and placement technique for reducing the number of sensors in thermal monitoring

Using embedded thermal sensors, dynamic thermal management (DTM) techniques measure runtime thermal behavior of high-performance microprocessors so as to prevent thermal runaway situations. The number of placed sensors should be minimized, while guaranteeing accurate tracking of hot spots and full thermal characterization. In this paper, we propose a rigid sensor allocation and placement technique for determining the minimal number of thermal sensors and the optimal locations while satisfying an expected accuracy of hot spot temperature error based on dual clustering. We analyze the false alarm rates of hot spots using the proposed methods in noise-free, with noise and sensor calibration scenarios, respectively. Experimental results confirm that our proposed methods are capable of accurately characterizing the temperatures of microprocessors.
