Unfortunately, the amplitude of the source of vibration is extremely small at low range of vibration frequencies and thus possesses additional challenge in the measurement. Two types of mass loaded PVDF piezofilm sensors are used to capture minute vibration with a special arrangement of the sensors for better efficiency. A signal conditioning circuit consisting of a buffer and comparator is investigated for processing the analog output from the active sensors. An artificial vibrator is used to simulate the ambient vibration and the frequency of which is measured by means of optical sensor independently. The output signals from the signal conditioning circuit and optical sensor are compared to measure the frequency of vibration of the source. It is found that at the very low frequency range up to 50 Hz, the sensor of low resonance frequency performs better whereas the performance of the sensor of comparatively higher resonance frequency is better in the frequency range of 50–70 Hz. Our system is able to measure low vibration frequency as low as 28 Hz with a high degree of repeatability.","PeriodicalId":339373,"journal":{"name":"2019 International Conference on Ubiquitous and Emerging Concepts on Sensors and Transducers (UEMCOS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123100654","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}

Under grid connected DFIG system operation, the non-linear loads connected to the system draw harmonic currents which distorts the grid injected currents. This paper proposes an active filtering technique so as to compensate the harmonic currents drawn by these non-linear loads. The proposed method produces harmonic currents which neutralizes the harmonic currents required by the non-linear load. A new vector control strategy is proposed for the grid side converter which produces the additional harmonic currents in addition to the transfer of slip power. This results in distortion of the grid converter current but the grid current remains undistorted and total harmonic distortion (THD) is reduced. The harmonic isolation of the load currents as required in the proposed vector control strategy is achieved by self-tuning filters (STF). The DFIG model along with the control strategy is designed using MATLAB/Simulink environment and the results validates the proposed control strategy.","PeriodicalId":339373,"journal":{"name":"2019 International Conference on Ubiquitous and Emerging Concepts on Sensors and Transducers (UEMCOS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121906590","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}

Modern surveillance system uses pervasive CCTV for recording surveillance video, so recording or capturing of video is not a problem. The main difficulties lie in the availability of human resources to observe and analyze the video clips for long hours. They are not only very exhaustive but are mostly quite costly. Automatically finding of abnormal or risky behavior significantly decreases the overhead to label and annotate the surveillance videos of huge number of hours. In the proposed technique abnormal changes in a surveillance frame is detected and achieved through image quality estimation by using Peak Signal to Noise Ratio (PSNR) and Structural Similarity Index Metric (SSIM). The proposed anomaly detection is done automatically at the remote place of surveillance where uncorrelated (less similar) frames of the video represents anomalies or abnormality. False alarms are avoided by sending the reference and abnormal frame the control room using 1-D DWT and 2-D DWT at the remote surveillance place. The results reported are quite encouraging and the model will suitably work in any wireless communication domain","PeriodicalId":339373,"journal":{"name":"2019 International Conference on Ubiquitous and Emerging Concepts on Sensors and Transducers (UEMCOS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131266988","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 double iterative computer method based on drift diffusion model has been used for our study. The bias current density has been varied from 0.5x108A/m2 to 10x108A/m2. The result shows that as we increase the bias current density, avalanche region becomes wider due to more space charge accumulation near the junction in the avalanche region. This behavior is shown in the E-Field vs. distance profile where the E-field gradually becomes flatter near the junction instead of sharp fall after a bias current density of 3 x 108A/m2 and thus approaches a p-i-n diode. Hence, the negative resistance obtained from the drift region which is mainly responsible for power generation becomes smaller than the resistance from the avalanche region. So, the efficiency also decreases after a bias current density of 3x108A/m2 from 16.63% at 0.5x108A/m2 to 3.8% at 10x108 A/m2 bias density.","PeriodicalId":339373,"journal":{"name":"2019 International Conference on Ubiquitous and Emerging Concepts on Sensors and Transducers (UEMCOS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130699500","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 the identifying process, it is extremely important to standardize the measurement and to identify the bioimpedance parameters which are unique to a particular tissue. The set of unique bioimpedance parameters is used to characterize the given tissue. The unique parameters should be independent of position or coordinate of the tissue. For example, the characterizing parameters of an apple tissue should be independent of the measurement position of the apple. Cole bioimpedance parameters along with few derived parameters from Cole parameters are investigated in this work. Applying ANOVA on the boimpedance parameters, unique bioimpedance parameters are identified for characterizing tissue of apple. The capability of the identified impedance parameters to distinguish different species of apple is shown. This verification clearly shows that the identified parameters can be used to monitor early diseases in fruits, to separate an odd fruit or to monitor quality of fruits. In short, a tissue characterizing process by means of bioimpedance parameters is presented.","PeriodicalId":339373,"journal":{"name":"2019 International Conference on Ubiquitous and Emerging Concepts on Sensors and Transducers (UEMCOS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133641260","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}
