In this study, a descriptive and correlation study for two selected systems is conducted using SPSS 19. The results show that the severity score average of Linux kernel vulnerabilities is lower by %30 than the severity score average of vulnerabilities of windows server 2008, and the time required to patch published vulnerabilities is relatively faster for commercial than open source software. However, a positive correlation between Windows server 2008's variables reveal the irony that severity scores and patch delays are moving in the same direction. The contribution of this article is to shed light on the perception about the security divide between open source and closed software under study that is, although the commercial companies respond faster, however, not according to the severity of vulnerabilities disclosed.","PeriodicalId":147797,"journal":{"name":"2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125741156","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}

The first VCO with Low Power (LP-VCO) operates at 1.6 GHz with 200 MHz frequency tuning range, the VCO core consume only 725 µW from 1.2 V supply, this VCO achieves a phase noise of −123.2 dBc/Hz and a Figure-of-Merit (FoM) of −185 dBc/Hz at 1 MHz frequency offset. The second VCO was designed to have wide tuning range frequency and low phase noise (WB-VCO). The latter operates from 3.28 GHz to 4.4 GHz and consume 6.7 mW from 1.2 V supply.

They are mainly used for identifying objects and people based on a combination of tags and readers. Nevertheless, this identification brings out many challenges and concerns including security which still remains an open issue. In this work, we present a survey of recent works dealing with security and privacy in RFID systems. Particularly, we compare and classify them according to which part of RFID system each solution could be applied, taking into account different requirements and parameters including their conformity to RFID standards. Hence, our comparative study targets to provide a wide and clear vision of these concerns as a dashboard to help determining the most appropriate solutions towards any security problem.","PeriodicalId":147797,"journal":{"name":"2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115925810","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}

However, battery operating temperature plays a vital role on the reliability, lifespan, safety and performance of EV and HV. Battery Thermal Management System (BTMS) must keep the operating temperature of the battery pack between 20 °C and 40 °C in order to achieve good performances and long lifespan. To this day, this task remains a challenging subject for the electric vehicle (EV) development. BTMS consumes energy from the on-board battery pack, thus reducing the range of the vehicle. In order to reduce this adverse impact, this paper presents a novel approach that takes advantage of the non-uniform surface distribution of li-ion battery cell, which results from complex reactions inside the cell. First, li-ion hotspots were identified and found next to the positive and negative tabs. Then, thermoelectric coolers (TEC) are mounted next to the tabs and in the center of the li-ion battery. The control circuit is designed to turn on and off TECs in order to reduce the parasitic power feeding the BTMS. Experimental results show the feasibility of this system.","PeriodicalId":147797,"journal":{"name":"2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127123363","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}

However, the vulnerable nature of the mobile ad hoc networks (MANETs) makes them very prone to an adversary's malicious attacks such as dropping data or sending fake data etc. As the demand of MANETs is increasing day by day, the problem of security especially in the network layer must be solved appropriately and in accordance with the special characteristics of MANETs. In this paper, we present some attacks against routing in MANETs, and we focus on analyzing the working process of AODV routing protocol which is a representative protocol of on-demand routing protocols in ad-hoc. Then we propose an enhancement design to AODV based on authentication, using digital signatures, in order to prevent potential routing attacks against this protocol from intruders and malicious nodes. Finally, we compare the effectiveness of our improved protocol with some related secure routing protocols from literature, and against some well known attacks.","PeriodicalId":147797,"journal":{"name":"2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130823510","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}
