To do it, two features are extracted and statistically analyzed. The first one represents the amount of muscular activity estimated from the root mean square of EMG signal. It is called Mean Normalized Root Mean Square (MNRMS). The second feature extracted from the force represents the Mean Normalized Force (MNF). Results showed that the force and muscular activity are higher when the subject does not apply on the grip just before the beginning of the exercise. Moreover, it was demonstrated a linear relationship between MNF and MNRMS whose slope is slightly higher when the subject exerts a mechanical preparation. Finally, results demonstrates that verbal encouragement during isometric contraction increases the physical activity in term of force when the subject prepare mentally his activity.","PeriodicalId":144578,"journal":{"name":"2018 International Conference on Internet of Things, Embedded Systems and Communications (IINTEC)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132030033","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}

Gharsallah","doi":"10.1109/IINTEC.2018.8695301","DOIUrl":"https://doi.org/10.1109/IINTEC.2018.8695301","url":null,"abstract":"The idea in this manuscript is to design a new form of Micro strip Patch antenna inspired by an ordinary patch antenna resonating at 2.45GHz for radio frequency identification (RFID) applications. Indeed, a special importance is given to a new and coherent form of E-patch based, also, on a new E-shaped SRR of meta-material placed on a superstrate. It is shown that by implementing innovative split ring resonators into the design, there is simultaneous gain and bandwidth improvement to 7.5 dbi and 150 MHz. The results in terms of gain, radiation pattern and return loss are analyzed in detail, which allows us to develop a comparative study according to the distance separating the proposed antenna and the ESRR placed in the superstrate. The simulation of this proposed antenna is done using transient solvers of CST Microwave Studio.","PeriodicalId":144578,"journal":{"name":"2018 International Conference on Internet of Things, Embedded Systems and Communications (IINTEC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133119795","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}
