In short, their aim is to take a small-time interval, expand it in the order of thousand to tens of thousand times and measure the resulting interval. The usual way they are being used is as a single standalone unit, doing all the work in a consecutive order for different time variant sources. In this paper we propose a different approach, consisting of multiple TTCs working in parallel, being synchronized to the first incoming event.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124833637","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 general, SAM can be designed to have extreme high functional density. However chemical reactions and perturbations can create variety of structures which are energetically stable.

We show that extended sampling method combined with dimensionality reduction scheme can be used for identification of preferable adduct conformations obtained under specific thermodynamics conditions at a fraction of the computational cost.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"1962 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129613511","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 cost and technical restrictions of strengthening the infrastructure at the same rate, alternative energy sources must be sought in order to meet these increased energy demands. This study presents a street lighting system which consumes minimum energy from the city network by using solar energy to charge the battery during the day. This intelligent charging system will increase battery life and store solar energy. During the night, the battery is used for illumination until it is depleted, and only then is the energy from the city network used. Moreover, with the development of TCP/IP communication with centralized software on the cloud via GSM, the high-efficiency LED lighting is managed and monitored according to the level of daylight and the volume of traffic detected. Thus, with this system, a lead-free environment, lower CO2 emissions and energy savings can be achieved.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114807593","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}
