Carrier Aggregation (CA), High Order Modulation (HOM), Multiple-input and Multiple-output (MIMO) utilization, channel estimation, equalization and Link Adaptation enabling techniques have been implemented and investigated in this model. This paper is achieved a transmission bandwidth of about 34.8500 and 19.9000 MHz by aggregating three non-symmetric and two symmetric component carriers (CCs), respectively. At high signal power regions, significant enhancement in the data rate obtained with 256-QAM which applied as HOM over limited transmission bandwidth. The paper also implemented different MIMO schemes that validate the capability of the system to deal with the fading nature of the channel, or its ability to accommodate higher data rates as the Signal-to-Noise Ratio (SNR) increases. To mitigate system degradation due to multipath fading, this paper examined two MIMO detection schemes with ideal and pilot-assisted channel estimation techniques. Finally, the paper showed that the available spectrum exploited efficiently with link adaptation techniques by increasing the number of supported subscribers.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"34 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":"133797083","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 power factor is analyzed based on three modulation techniques: conventional phase shift modulation (PSM), triangular current modulation (TriCM), and trapezoidal current modulation (TrpCM). The analysis shows that the HF transformer suffers from poor power factor under PSM operating condition compared to both TriCM and TrpCM techniques. Poor power factor is another meaning of low efficiency and high power loss. On the other side, the voltage operation range of the converter is limited under both TriCM and TrpCM switching control methods. To extend the operating voltage range and achieving high power factor condition, combining both triangular and trapezoidal modulation methods is considered and analyzed in this research. The power factor is significantly improved as both TriCM and TrpCM techniques are combined. A deep mathematical representation for the HF transformer power factor, current, and transferred power are presented for each modulation technique. Matlab simulation tools are used to analyze and verify the derived power factor equations.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"72 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":"116179467","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 deception detection systems (DDSs) based on facial expressions are non-invasive, mobile and cost-effective. In this work a DDS is dependent on Facial Action Coding System (FACS) for facial features extraction, the main idea of FACS is to describe all facial actions using Action Units (AUs), each AU is related to movement one or more facial muscles. Eight AUs are used which incorporated into a single facial behavior pattern vector; these AUs are AUs 5, 6, 7, 10, 12, 14, 23, and 28. Datasets are collected for 43 subjects (20males, 23 females) most of them between ages 18-25. Four types of classification algorithms are used individually in the last stage of the proposed system; these classifiers are MLP, KNN, VG-RAM, and SVM. The simulation results show that the best results are obtaining when using VG-RAM and KNN classifiers. The main contributions of this work are new classification techniques in DDS, collect real database that can use to measure the performance of any DDS based on facial expressions, and select suitable facial features.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"17 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":"127876642","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 proposed antenna is constructed of a monopole of an open mouth flower patch mounted on an FR4 substrate and followed by an HS array. The antenna is backed with a partial ground plane to enhance the antenna bandwidth. The stability in the antenna radiation pattern over the entire frequency band is achieved by introducing three rows of the proposed HS based on H-Resonators (HS-HR) next to the patch edge. Such arrays provide an Omni directional antenna at several frequency bands that suit the application of RF energy harvesting. The array of the proposed HS-HR provides high electromagnetic impedance within the frequency band of interest toward the patch length. Numerical simulations are accompanied using CST MWS and HFSS software packages to evaluate the antenna performance. Finally, the related measurements to the antenna performance and RF harvesting are conducted at 2.45GHz. It is found that the proposed antenna provides a conversion efficiency of 35% with an acceptable gain-bandwidth product.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"130 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":"126803626","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}
