Feature extraction is the best technique which preserves the essential information of the input image. In this paper we propose offline signature verification based on Transform domain feature such as gradient, coherence and dominant local orientation. The acquired image is resized to bring all the signatures into a uniform size. The images are thinned using morphological process. The DWT technique is applied on signature images to get LL, LH, HL and HH subbands. The directional information feature is computed from the subbands. The directional features and textural features are concatenated to form the feature vector. The Feed Forward ANN tool in MATLAB is used for classification and verification. The results of False Rejection Rate (FAR), False Acceptance Rate (FAR) and Total Success Rate (TSR) are obtained for GPDS-960 database. A total of 360 images are used for training and testing. It is observed that the values of FRR, FAR and TSR are improved compared to the existing algorithms.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133733099","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 radiations from heatsinks are undesirable to the nearby antenna component and should be minimized to reduce electromagnetic interference (EMI). However, in certain applications the heatsink components are in the circuit is unavoidable. The use of heatsink as a transmitting or receiving electromagnetic radiation will be of significant value if heatsink is designed as an antenna, instead of having two separate components: antenna and heatsink. This paper investigates the radiation property of heatsinks as an antenna at two different frequencies: low (2.4 GHz) and high (24 GHz) frequencies. The fabrication of heatsink antennas depend on the designed resonant frequency. As the antennas are made smaller, their resonant frequency increases. Building millimeter-wave capable antennas via conventional semiconductor processing techniques becomes feasible. The fabrication of high frequency on-chip 3D heatsink antennas can be visualized using a novel self assembly process. The self assembly (SA) technique is driven by surface tension property to pull 2D metal patterns into 3D structures. The SA method involves conventional semiconductor steps with an additional dip soldering and reflow steps to develop 3D heatsinks. The 3D heatsink shows improved antenna properties at low and high frequencies.","PeriodicalId":194102,"journal":{"name":"2013 International conference on Circuits, Controls and Communications (CCUBE)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117319419","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}

Considering a flat Rayleigh fading channel environment, the MATLAB simulation and analysis are carried out. In the cooperative phase, two relays are employed, where each one of them (relays) transmitting each row Alamouti code. Here SNR threshold selection depends on the target rate information. The closed form expression for average channel capacity with tight upper bound is derived and compared with the simulation done in MATLAB environment.

The large antenna array is divided into sub arrays and only sub array outputs are used to estimate the spatial spectrum in order to reduce the system complexity and computational load. Only local super resolution can be achieved with sub array outputs by forming the array manifold vector with sub array phase centers and gains. The spatial spectrum and sub array formation are closely related. In this paper the effect of grating lobes on the original main lobe by using Spot-light MUSIC is explained in detail.
