CuO thin films were electrodeposited at different voltage and different temperature whereas bath concentration, pH and time were kept constant. The characterization of the CuO thin films deposited at different electrodeposition conditions were conducted by Scanning Electron Microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDS). The SEM study showed the grain sizes of CuO thin films decreased at more negative potentials. Film thickness with regards to voltage and temperature are analysed. Absorption spectrum was obtained from UV-Vis absorption spectroscopy. Subsequently, the optical band gap was determined from their absorption spectrum by using Tauc's equation. It was found that CuO thin films deposited at low voltage have lower band gap than that of films deposited at higher voltage due to crystalline, uniform and compact grains. The band gap decreases with increasing operating temperature.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"465 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128047151","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}

Besides the advantages, a CMOS image sensor suffers from noises, less sensitivity as well as lacks of Dynamic Range (DR). Logarithmic response Active Pixel Sensor (APS) is a solution for wide dynamic range imager maintaining high fill factor. 3T Linear APS (Active Pixel Sensor) has better performance in low illumination, but very poor sensitivity in low illumination. For 3T logarithmic APS has satisfactory performance in high illumination, but limited sensitivity in low illumination. Few reported to implement both linear and logarithmic capture for a single frame which increases the capture time. Implementation of in-pixel circuitry to combine both linear and logarithmic in a single capture which decreases the fill factor of the pixel is also reported. In this paper, we propose a self-adjusting pixel to combine linear and logarithmic response maintaining high fill factor. The proposed pixel was simulated in Cadence Virtuoso in 180nm technology node and analyzed for comparative study of dynamic range.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115362513","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 higher propagation speed of radio frequency (RF) wave keeps the RF based underwater networks into focus for supporting such fast detection requirements. In light of this, this paper proposes two three dimensional (3D) cluster-based UWSN architectures and scrutinizes them for identifying and tracking submerged moving intruders. The UWSN senses the presence of an intruder within the surveillance area and instantaneously transfers the data to an onshore base station (BS) for tracking the intruder. All the communication links from the intruder sensing nodes to the BS are RF based. The BS is also equipped with the essential mathematical tools for identifying and tracking an intruder. Extensive simulations are carried out for evaluating the performance of the deployed architectures in a seawater environment. Accuracy in tracking by the topologies is thoroughly examined in terms of error in estimated travelled distance as well as travelled direction. Influence of various system parameters on the performance is also reasonably analyzed.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123064378","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}
