Battery replacement remains a deterrent towards mass implementation of active RFID tag technology. Within this context, rectenna architecture has been investigated as the RF power transfer mechanism for ultra low power on-body communication. A working prototype consisting of 7-stage Cockroft-Walton voltage multiplier integrated with band pass filter and lowpass filter has successfully been developed on 1.57 mm RT/Duroid 5880 laminate with the goal of prolonging battery lifespan. A qualitative assessment is proposed as means of evaluating rectenna performance with various antenna designs connected to optimized rectifier. Under non-controlled environment, powering an LED from a Wireless Access Point transmitter source can be used to gauge robustness of rectenna system. Antenna with 5 dBi gain was capable of powering LED at 10 cm distance from RF source.","PeriodicalId":125957,"journal":{"name":"2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116741841","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 first method is based of the harmonic analysis of the induced voltage in a search coil placed on the inner periphery of the stator, while the second relies on the analysis of the induced voltage in the stator windings. Accurate results can be achieved since the measurement procedure relies only on well defined electrical quantities regardless of the dimensions of the machine. A further appreciation of the accuracy of the proposed measurement procedures can be confirmed by the reconstruction of the stator induced voltages. Although each method has its own merit in terms of field sensing, they are basically identical; nonetheless they enable a cross comparison of the measured results.","PeriodicalId":125957,"journal":{"name":"2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123543506","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}

This work is based on the modified LEACH protocol to develop our algorithm which supports node mobility and improves network lifetime. We consider a heterogeneous WSN which consists of a large number of sensor nodes, a few static cluster heads (CH) and a mobile Base Station (BS). Each sensor node periodically sends sensed event packets to its nearest CH. The CH should found an itinerary to send these event packets to the mobile BS. To show that the proposed approach achieves the required reliability and also maximize the network lifetime, we compare this protocol with an algorithm dedicated to a network formed by fixed nodes only. Simulation results show that the proposed mobile multi-hop algorithm, based on adaptive clustering protocol, effectively produces optimal energy consumption for the wireless sensors network and improves the network lifetime compared to other approaches.","PeriodicalId":125957,"journal":{"name":"2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128368860","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 effect of valve failure is not only major production loss but also high maintenance cost. In a plant, a common technique used for valve maintenance is based on the valve condition replacement at fixed time interval. Most of the time the replacement only happens after the valve has obvious failure and during the plant shutdown. Common case of failure in valves is the internal valve seat leakage. The valve leak tightness test is conducted to detect the occurrence of internal leak in valve, however it is costly and time consuming to isolate the valve from the site and dismantling the valve. Significant money can be saved if leak in the valve can be detected early and if the test can be conducted online without having to isolate the equipment from the site. Therefore, this paper aims to study the effectiveness of Acoustic Emission technique in detecting early leakage in control valve on-site with fully closed position. The paper discusses a method based on different types of statistical analysis parameters such as variance, standard deviation, max amplitude on frequency domain analysis of AE signals to distinguish between healthy and unhealthy control valves. A real time AE measurement system is developed and tested. The acquired AE signatures are processed and analyzed using MATLAB.","PeriodicalId":125957,"journal":{"name":"2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128573889","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}
