The performance of the Tunnel FET (TFET) by modulating the doping concentration in the drain region has been realized. For the realization of the tunnel FET in electronic device simulation non-local band to band tunneling (BTBT) model is utilized. The TFET device proposed in this work is tubular type in which there is a gate inside and outside the tube, due to which the controlling capacity over the charge carriers is excellent. Results have been compared with 45 nm gate length conventional Silicon nano-tube tunnel FET. It has been realized that on decreasing the doping of the split drain region, the ambipolar current decreased from 10-9 A/μm to 10-11 A/μm, due to which it becomes suitable for low power memory applications, devices, and FETs. The outcomes show that the drive capability of the devices is increased.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125528228","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 the challenges in 5G network is massive connectivity regarding the number of devices and data volume without spectrum increase. In the SCMA structure, each allocated resource can be accessed by several users at the same frequency and time, which is called the overload factor. This paper investigates MIMO–SCMA performance with various overload scenarios under Rayleigh and AWGN channel models. For single SCMA and MIMO– SCMA with an increased overloading factor up to 300%, the result shows that the processing time significantly increases, and the bit error rate performance is underperformed. However, MIMO-SCMA performance is outperformed others in bit error rate, but processing time complexity is still higher than single SCMA.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123112858","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}

Several distances and radiation angles of the far UV-C beam was experimentally measured using an UV optical spectrum meter. As a result, the beam has irradiance loss of 0.02 – 0.2 dB/cm and beam radiation angle of about 150 degree for vertical and 180 degree for horizontal.

The previous studies provide information on the brief history of the exoskeleton for gait rehabilitation as well as the various structural, mechanical, and control designs of exoskeletons. Based on the references, we design a simple lower limb exoskeleton and formulate the prototyping and testing plan, from CAD modeling, followed by 3D printing of the model, mockup testing, until prototyping and the clinical test of the prototype. This article describes the preliminary stage of exoskeleton design especially the design process and the results in the form of exoskeleton conceptual design and scale model 1:2.

Despite the promising features of PEDOT:PSS, the high acidity of the PSS chain is known to compromise the stability of the devices. To address this issue, we propose alternative HTL materials. This study uses copper (I) thiocyanate (CuSCN) prepared from aqueous ammonia solvent as the HTL in efficient nonfullerene-based OPVs.

Smart glove system prototype based on Arduino UNO microcontroller, ultrasonic and flame sensors, SIM800L GSM module for communication, and buzzer for alarm notification. Then, the complete device prototype was tested using both the acrylic box and embedded at one’s hand as a proof of concept for emphasizing the reliability and usefulness of our work. The results show that the ultrasonic sensor works well for detecting an object with a coverage of 40 cm from the blind. The fire/flame sensor also works well when using fire detection mode for detecting the small fire from matches or lighter at a distance of about 15 cm or big fire from a burnt paper at a distance of about 20 cm and will be sending a short message to the respected person through SIM800L GSM. The only drawback for this device is a bit heavy when used on hand and still lacks an IoT system. However, further research will be conducted to overcome those problems soon.","PeriodicalId":269759,"journal":{"name":"2021 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130960201","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}
