However, if we require just SPI over long distances currently there is no effective low-cost solution. A SerDes provides a solution to this shortcoming by sending parallel data as a serial transmission and converting it back at the receiver end. However, most of the current SerDes implementations are expensive to implement and cater to very high-speed applications, which is not the case in SPI. In this paper, we present a simple to implement and low cost SerDes solution for sending and receiving multiple SPI and GPIO lines. Our proposed solution makes use of a low cost CLPD / FPGA and is applicable for low data rate applications such as SPI. This paper investigates the simplest solution to the problem, whilst maintaining a reliable single wire / optical link. For testing, we have implemented three novel encoding schemes that all provided good results, each measured by performance against resource usage. One of these encoding schemes has shown a drop-out rate as low as 0.001% over a 24-hour period. Our proposed solution when used in conjunction with an optical fibre medium could potentially allow SPI transmission over several kilometres of distance.","PeriodicalId":447663,"journal":{"name":"2018 IEEE International Symposium on Smart Electronic Systems (iSES) (Formerly iNiS)","volume":"6 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":"116860917","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 cost and time issue involved in this task has motivated us to devise a cost effective and portable hardware, capable of adding functionality of smart meters into traditional meters. This paper describes the method for measuring active power registered by traditional meters in real time. Considering the worst case as, cases when traditional meter registers less than 10 watt, the proposed system can provide its users with active power consumption data in 101.25 seconds as against monthly billing cycle of traditional meters. The proposed system uses LDR for sensing the frequency of LED present on the meter, which blinks at a frequency proportional to the active power registered by traditional meters. It also uses ESP8266-12e to compute the active power of load connected across traditional meter, from sensed value of blinking frequency of LED and store it in an online data server.","PeriodicalId":447663,"journal":{"name":"2018 IEEE International Symposium on Smart Electronic Systems (iSES) (Formerly iNiS)","volume":"5 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":"115472187","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}

For generating partial products in the multiplier, a newly designed AND gate approach is proposed. All the proposed designs are simulated using 90nm UMC technology. The Simulation results indicate that the number of transistors and power consumption of approximate multipliers are reduced by 28% and 32% respectively as compared to conventional Dadda multiplier.

The sensor nodes (SNs) are tasked to monitor a large region of interest (ROI) and report their test statistics to the fusion center (FC) over a wireless fading channel. To maximize the lifetime of the WSN and enable long range communication with minimal transmit power, the long range wide area network (LoRaWAN) communication protocol is adopted. Each of the SN is designed and enabled with several state of the art sensors in order to estimate different and diverse parameters of interest (e.g., soil moisture, soil temperature, and salinity at different soil depth; barometric pressure, ambient humidity, leaf wetness, and etc.). The core feature of the proposed solution is that the SNs learn and adopt over the sensing time. This is very important in extending the operational lifetime of the WSN. The proposed system is validated through the infield experiments using few concept devices. Experimental results show that the proposed WSN features an effective large ROI monitoring with minimal number of SNs, a significantly reduced SN transmission power required and thus an extended WSN operational lifetime.","PeriodicalId":447663,"journal":{"name":"2018 IEEE International Symposium on Smart Electronic Systems (iSES) (Formerly iNiS)","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":"133413823","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 this paper we adapt CNN architecture of deep neural nets for non-intrusive appliance identification which is a sub-problem for practically useful NILM.

We have proposed NILM as one subject under the research subfield of energy informatics and energy disaggregation as a method for implementing NILM.
