Synchronous or lock-in measurement related problems are discussed in the current paper, and new solution is proposed for detection of bioimpedance variations. Proposed method is believed to be simpler, and more robust compared to known solutions. In the heart of the method is lockin integrator, used as differentiating peak detector. The base component of the signal is rejected, giving better dynamic range for the information carrying variable component of the bioimpedance due to the apparent differentiation. Reduction of the additive off band signals and noise is considered as well.","PeriodicalId":140384,"journal":{"name":"2018 16th Biennial Baltic Electronics Conference (BEC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126798372","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}

Micro Intelligent Vehicles (MicroIV) are commonly used as a more cost efficient, easier and faster way to develop innovations in this field. As GPS is a crucial component in autonomous driving scenarios but is not practical for use at MicroIV scales, alternative solutions are needed. This paper proposes a scalable, low-cost positioning system based on image processing, that can be used as a replacement for GPS in indoor facilities.","PeriodicalId":140384,"journal":{"name":"2018 16th Biennial Baltic Electronics Conference (BEC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128163019","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}

Graphene has emerged as a potential candidate for electronic sensors and optical sensors applications. The purpose of the work presented in this article is to contribute in this novel field by simulating graphene nano-sheet based sensor to detect phenol and methanol molecules. QuantumWise Atomistix Toolkit (ATK) software has been used to carry out the sensor simulations. A significant change in the density of states and conductivity of the graphene have been noticed in the proximity of the target molecules. This change in the conductivity of graphene nano-sheet has been used as a detection signal. These simulations lay the groundwork for our physical experiments, which are targeted to produce a cheap sensor.","PeriodicalId":140384,"journal":{"name":"2018 16th Biennial Baltic Electronics Conference (BEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131379277","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}

Using retransmission approaches has been proposed in the literature for handling SETs in Network-on-Chip (NoC) links. However, those approaches either suffer from significant latency overhead or impose additional retransmission buffers, which consume more area. This paper proposes the ReUSE mechanism as a transient fault mitigation mechanism for Network-on-Chip links. The mechanism takes advantage of the inherent redundancy in the input buffers of NoC routers and reuses these for SET mitigation on the NoC links. By using a parity checker for fault detection, the approach can cover all SETs during run-time and return to normal operation in maximum one clock cycle after the disappearance of the fault. The experimental results show that the proposed mechanism prevents network-wide failure even in harsh environments with up to 80 million random faults on links per second. The ReUSE mechanism imposes 18% area overhead and 7.8% critical path delay overhead to the baseline NoC router.","PeriodicalId":140384,"journal":{"name":"2018 16th Biennial Baltic Electronics Conference (BEC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127098115","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}

A simple and fast computable lower bound is proposed to be used for pruning the search space of the B&B algorithm.

On the other hand, battery technologies have not improved fast enough to cope with these needs. Thus, miniaturized energy harvesting technologies are increasingly used to complement the batteries in WBANs. However, this brings uncertainties in the system since the harvested energy varies a lot during the node operation. It has been shown that reinforcement learning algorithms can be used to manage the energy in the nodes since they are able to make decisions under uncertainty. But the efficiency of these algorithms depends on their reward function. In this paper we explore different reward functions and seek to identify the most suitable variables to use in such functions to obtain the expected behavior. Experimental results with four different reward functions illustrate how the choice thereof impacts the energy consumption of the nodes.","PeriodicalId":140384,"journal":{"name":"2018 16th Biennial Baltic Electronics Conference (BEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128225528","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}
