Using mobile chargers in wireless rechargeable sensor networks is an option for charging the nodes due to the high cost of power chargers. In order to achieve some performance requirement such as coverage, it is necessary to effectively schedule the mobile chargers to serve every node in the network. We notice that nearly all previous works on mobile charger scheduling assume that the mobile ch...

In this paper, we investigate the mobile charging in rechargeable sensor networks. By utilizing the historic charging information, the mobile charger can prefetch the charging requests from sensor nodes before they are sent out, and thus both the charging latency of sensor nodes and the travel distance of mobile charger can be reduced. Furthermore, by controlling the amount of energy to charge ...

Rapid growth in the complexity of wireless devices, communication protocols, and applications, combined with slow improvements in battery technologies, have created a “battery gap” that is only projected to increase with advances in wireless communication technologies and applications. Conventional approaches to bridging this gap exploit low-power network protocols and handset architectures. Ho...

electrochemical properties of various rock-shaped-cuo/graphite (g) composites and monoclinic structure cuo nanoparticles as the cathode versus a zinc plate as the anode in a 4m naoh electrolyte were elucidated by electrochemical impedance spectroscopy (eis) and chronopotentiometry (cp) in a two electrode configuration cell. various values of g 9, 16 and 28 wt% were prepared and studied as catho...

ENVS135 American Food This course investigates topics in the history of food production from the colonial period to the present, with emphasis on the American contribution to the development of world food systems and cultures of consumption. Topics to be addressed include the production of agricultural commodities, development of national markets, mass production of food, industrialization of a...

In this paper we present an overview of the mining track in the Social Book Search (SBS) lab 2016. The mining track addressed two tasks: (1) classifying forum posts as book search requests, and (2) linking book title mentions in forum posts to unique book IDs in a database. Both tasks are important steps in the process of solving complex search tasks within online reader communities. We prepare...

Recharging decisions for electric vehicles require many special considerations due to battery dynamics. Battery longevity is prolonged by recharging less frequently and at slower rates, and also by not charging the battery too close to its maximum capacity. In this paper, we address the problem of finding an optimal recharging policy for an electric vehicle along a given path. The path consists...
