In order to study effecting law of driving clearance to Gatling gun's system resistance moment and core's force, based on dynamics theory of mechanism system with clearance, and through analyzing motion and force of cam drive mechanism, dynamics coupled equation of cam mechanism with clearance is built by Dubowsky's impact model.

In this paper, a novel static voltage scheduling algorithm for battery-aware dynamic voltage scaling (DVS) systems is presented. The proposed algorithm pays fully attention to the relationship of the factors (the increase of the slack time and discharge) related to battery consumption by taking the nonlinearity characteristics of the battery into account. We focus on the decreasing speed of the cost function which is a critical parameter in energy saving. The proposed algorithm can get the fastest speed in cost function decreasing and finally return a profile in accordance with the profile obtained by brute-force searching. Aperiodic and periodic tasks on uniprocessor and multiprocessor are considered in the proposed algorithm to make our algorithm widely used.","PeriodicalId":6316,"journal":{"name":"2011 IEEE 2nd International Conference on Computing, Control and Industrial Engineering","volume":"27 1","pages":"90-93"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89753765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
