The shielding technique is performed by different electromagnetic absorbing materials. Electromagnetic absorbers used in shielding are glass, FR-4, teflon, Nickel, Gallium Arsenide and Silicon. Specific absorption rate reduction factor of 48.38% averaged over 1 gm of mass is achieved. The infinity-shaped structure is a new metamaterial structure which is used in shielding. The infinity-shaped structure achieves specific absorption rate reduction factor of 53.8% averaged over 1 gm of mass tissue. The standard anthropomorphic mannequin phantom human head model at 900 MHz is presented. Specific absorption rate distribution and radiation pattern are analyzed, as well, to verify the performance of the model and the antenna. Simulations show the effect of changing the thickness and the width of the shield on the specific absorption rate value.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"245 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":"122060236","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}

These vehicles are more convenient, more energy efficient providing higher safety level and cheaper driving solutions. In addition, decreasing the generation of CO2, and the risk vehicular accidents are other benefits of autonomous vehicles. However, leveraging a full autonomous system is challenging and the proposed solutions are newfound. Providing a testbed for evaluating new algorithms is beneficial for researchers and hardware developers to verify the real impact of their solutions. The existence of testing environment is a low-cost infrastructure leading to increase the time-to-market of novel ideas.

The frequency agility is achieved via integrating ideal switches with the DRA structure employed for microwave applications. The first model investigates the integration of five switches on the DRA surface to connect the printed metallic ring and the ground plane. The resonance frequency and the impedance matching bandwidth are controled by the combination of the switches states to be ON and OFF. The resonance frequency is varied from 9.7 GHz to 11.5 GHz with 190 MHz bandwidth. In the second model a conducting plate is printed on the top of the DRA and eight metallic switches connect it with the ground through eight metallic strips. The reconfigurable frequency of the antenna is changed from 6.2 GHz to 8.08 GHz. A full-wave analysis is used to model and analyze the radiation characterstics of the antenna structure. A time domain based finite integral technique (FIT) and frequency domain finite element method (FEM) are employed.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","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":"129242618","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}

In some cases, the explosions recorded as an earthquake or vice verse, which can contaminate the seismic catalog. Rapid discrimination is required to support the real-time seismic application. The discrimination algorithm is based on a wavelet filter bank to extract the discriminative features, and support vector machine (SVM) as a classifier. Therefore; we propose to optimize the hardware implementation of the discrimination algorithm on Field Programmable Gate Array (FPGA). First, we implement the wavelet filter bank using optimized lifting scheme. Then, we utilize the linear classifier to implement the SVM classifier. Finally, we optimize the hardware resources of the discrimination algorithm to be utilized on low-cost FPGA called TE0711 board (Xilinx Artix7). The implemented design is utilized 1.2% and 39.8% of the FPGA's Look Up Table (LUT) and register resources, respectively.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"24 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":"123112225","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}

This rectifier provides enhanced efficiency at low input power levels compared to the typical Greinacher voltage doubler rectifier. The proposed rectifier consists - in addition to the 180° hybrid combiner - of two rectifying branches and two output ports. Each rectifying branch is based on the Greinacher voltage doubler configuration but contains only one rectifying diode for each branch. Using of only one diode instead of two provides significant improvement in the efficiency of the RF rectifier. The proposed rectifier configuration has been simulated using advanced design system (ADS) and its performance has been investigated and compared to the ordinary voltage doubler rectifier. The proposed rectifier provides maximum power conversion efficiency (PCE) of 70 % compared to maximum PCE of 51 % for the ordinary voltage doubler circuit. Moreover, the proposed rectifier topology provides sensible enhancement of the efficiency at the lower input power levels.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"409 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":"132898542","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}

One of these protocols is message queuing telemetry transport (MQTT), which is an approach based on the information centric network (ICN) technology. However, MQTT must be operated over IP and its related protocols; therefore, the co-operation between MQTT and these protocols is an interesting topic of study. One of the issues related to the abovementioned study is the mechanism to transfer information assuredly. MQTT provides some mechanisms for the assured transfer of information such as “Quality of Service (QoS) classes” with several options such as QoSO, QoSl, and QoS2. TCP also provides a re-transmission scheme for this purpose. This study surveys the mechanism based on MQTT QoS classes, and discusses transmission performance with comparisons among TCP based and MQTT QoS class-based approaches. It concludes that the QoSl in MQTT can be invoked to perform an assured transfer of information with small delay.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"108 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":"115624070","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}

In addition, the proposed algorithm gives the designer full control of the resulting error which can be conveniently determined for each application.
