We propose an IEEE 754-based approximate floating-point adder that applies to the leaky integrate-and-fire (LIF) neuron-based SNN operation for both training and inference. The experimental results under a two-layer SNN for MNIST handwritten digit recognition application show that 4-bit exact mantissa adder with 19-bit approximation for lower-part OR adder (LOA), instead of 23-bit full-precision mantissa adder, can be exploited to maintain good classification accuracy. When adopted LOA as mantissa adder, it can achieve up to 74.1% and 96.5% of power and energy saving, respectively.","PeriodicalId":170294,"journal":{"name":"2021 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114942336","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 device is able to apply for the building energy management system. The system is consist of two parts, which are sensors and NETPIE platform; both are connected via internet in MQTT protocol. This become the guideline for Internet of Things (IoT) device installation in building that is connected via internet by Wi-Fi. For the testing, we measures the receive signal strange indicator (RSSI) at three separated areas, including staff room, terrace and elevator front. The result shows the lowest signal is at elevator front because of distance from the switch hub and obstacles. However, this experiment show that all data are transfers. Furthermore, the result can be used for designing of Wi-Fi network installation for IoT devices.","PeriodicalId":170294,"journal":{"name":"2021 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131354891","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, ternary hardware implementation is in theoretical, simulation levels. Moreover, no hardware description language for ternary logic is developed. In this paper, by representing 1 trit (trinary digit) with 2 bit, ternary logic is implemented and analyzed in FPGA. To specify the performance of TVL, ternary carry lookahead adder is implemented on FPGA and the speed and power dissipation of the arithmetic unit are measured. The performance of 21-trit ternary CLA is compared with 32-bit binary CLA. The results show that ternary CLA is faster up to 10.36% and consumes 13.54% less power than binary CLA. In addition, performances of ripple carry adder using both ternary and binary logic are simulated.","PeriodicalId":170294,"journal":{"name":"2021 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126731060","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}

Due to the movements and perturbations of UAV, maintaining beam alignment is a challenging issue. In this paper, we propose an integrated flight sensor data and beamforming algorithm for UAV tracking. We can reduce the beam training overhead drastically with the global positioning system (GPS). However, due to relatively large errors and a long period of the GPS signal data, we consider exploiting beamforming to persist the beam alignment even when the GPS signal is absent. The simulation results show that the proposed scheme can improve the performance compared to a GPS-single system. In addition, the proposed algorithm can accomplish high beamforming gain with less beam training overhead compared to the conventional beamforming algorithm.","PeriodicalId":170294,"journal":{"name":"2021 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123012873","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 signals need to be monitored since they are important signals to notice the transformer failure. To prevent this, the monitoring system of transformer uses a high-speed data acquisition system to extract various physical quantities from the raw abnormal signal. Among the types of abnormal signals, partial discharge (PD) is caused by failure of the insulator, which has a great influence on the life and maintenance of the transformer. In this paper, a PD signal is mimicked by using a PD generator to analyze the partial discharge of a transformer. PD signal is simply analyzed by fast Fourier transform. Also, by proposing a simple monitoring system, it is introduced that a communication method of root-mean-square (RMS) value, maximum value, and maximum RMS value.","PeriodicalId":170294,"journal":{"name":"2021 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121243708","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}
