The absorption spectra recorded show an optical band edge at 400 nm for both the cases. In the case of TBOB, a solvation mediated large shift (of about 130 nm) in the photoluminescence (PL) spectra is observed. The density function theory (DFT) calculations performed for TBOB compound suggest that the typical molecule has a planar geometry with highly localized charge densities, responsible for the experimentally observed large hypsochromic shift in the PL spectra. The results of thermo gravimetric analysis (TGA) performed on TBTB and TBOB compounds indicate thermal stability, with melting points >2000C and decomposition temperatures >5000C. The electrochemical properties of TBTB and TBOB were examined with cyclic voltammeter. The light emitting device fabricated using TBTB compound showed the current density ~0.012 A/cm2 at 14 V, with the turn-on voltage at 7 V.","PeriodicalId":322442,"journal":{"name":"2016 International Conference on Emerging Trends in Electrical Electronics & Sustainable Energy Systems (ICETEESES)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115664083","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}

Unfortunately, accuracy of Latent fingerprint matching is still difficult implication and challenging until today. To find the similarity between two images is a trivial task. This process becomes more challenging and risky, when among two input images one is poor quality, such as a latent fingerprint. Latent fingerprints are distorted, partial and having background noise. The main motto of this research is to design an intelligent procedure equivalent to human perception in matching the latent to exemplar fingerprint scenario. In this paper, a new Kernel-based structural similarity measure algorithm is designed for match score computation. The proposed approach is more robust to invariance such as scale change and rotation in the input image. The result describe, that the similarity score value is improved by 1.6% on an average as compared to existing similarity calculation approach.","PeriodicalId":322442,"journal":{"name":"2016 International Conference on Emerging Trends in Electrical Electronics & Sustainable Energy Systems (ICETEESES)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127643752","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}
