Objectives:Traffic scenes in road network needs to be monitored in different dimensional perspective to address the issues generated at various time instances. One of the major challenges observed in traffic scenes in road network is to address the vehicle tracking at different dimensional perspective for various time instances. One such application that has received greater significance is the mechanism to develop a full proof vehicle traffic control scheme. Videos fitted on different proposition of the signal junction able to view at respective image positioning and the overall traffic may rise to abnormality. Many studies have been examined for vehicle traffic control scheme. The recently used scheme is model based on simple object recognition and localization of road vehicles based on the position and orientation of vehicle image data. But the drawback of the approach is that if the shape of the vehicle and its pose varies in multiple junction coordination, the model based recognition is an inefficient one. To overcome the issues, in this work we are going to implement surveillance image object recognition and localization using improved local gradient model. The vehicle-object shape recognition and pose recovery in the traffic junction is carried out for varied traffic densities. An experimental evaluation is carried out to estimate the performance of the proposed Surveillance of Vehicle Object Recognition and Localization (SVORL) using improved gradient model in terms of vehicle density, traffic junction points, and computation time and compared with an existing model based on simple object recognition and localization. © 2005 - 2014 JATIT & LLS.

ZnO nanostructures have been successfully prepared by microwave irradiation method. The synthesized samples were characterized by X-ray Diffraction method (XRD), Scanning electron microscope (SEM), Transmission Electron microscopy (TEM), and Energy Dispersive X-ray Analysis (EDAX) and Fourier Transform Infrared Spectroscopy (FTIR) technique. The absorption edge and band gap of ZnO were calculated by UV-visible spectra. Highly crystalline ZnO nanostructures have been obtained by the microwave assisted procedure. Furthermore, the formation of these ZnO nanostructures can be obtained within short times (5, 10 and 15 minutes) by a fine tuning of the microwave irradiation. © 2015, Sphinx Knowledge House.

A microwave-assisted combustion route for the preparation of cadmium oxide (CdO) nanowire is carried and its characterization results are discussed. This method resembles a supportive way in the formation of CdO nanowire which is confirmed with the structure and morphological analysis carried for the prepared sample. Microwave combustion method is a cost effective and less time consumption to achieve CdO nanowires. The controlled shapes and size are attained due to microwave irradiation. Yielded sample is investigated with Fourier transformation infra-red (FTIR) spectra, X-ray diffraction (XRD) pattern, energy dispersive X-ray (EDX) spectra and transmission electron microscopy (TEM) with SAED pattern. The formation of CdO phase with a face centered cubic structure is confirmed from XRD spectra and the presence of Cd-O metallic bond is also confirmed with FTIR spectra. The formation of CdO nanowires is visualized through the TEM images and presence of elements is also recorded from EDX spectra. © 2012 Elsevier B.V. All rights reserved. Source

Problem statement: Mobile Ad-hoc Network is infrastructureless network supported by no fixed trusted infrastructure. The packets had a chance to drop or hacked by eavesdropper during transmission. So, encryption method is required for sending and receiving packet in secret manner. Approach: In this approach, the block and key size had been increased by 256 bits. When compared to Rijndael algorithm, it was more secure and effective. To attain security goals like: authentication, integrity, non- repudation, privacy, a secret key was necessary to be shared between the sender and receiver. For data communication, we use MAC address for exchanging packet with encrypted key exchange system. Results: For encryption, In Rijndael algorithm the whole data had to be run twice but our proposed algorithm would encrypt the whole data and run once. The encryption was done with neighborhood key and with message specific key for the enhancement of security. Conclusion: In our algorithm, the time required to break an encryption scheme is excessive as the key size is larger. Here the security is focusing the application level. The forward and backward security is ensured with neighborhood and with message specific key for the route discovery. © 2012 Science Publications. Source

CdO hexagonal sheets were prepared by a simple chemical route assisted by microwave irradiation. Two different preparation procedures were adopted and characterized in the presence of urea as a directing agent and poly-vinyl-pyrrolidone (PVP) as a surfactant. The morphological and microstructural characteristics were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM) analysis, diffuse reflectance infrared spectroscopy (DRIFT) and X-ray powder diffraction (XRD). Characterization results have demonstrated that, after annealing at 300 °C, the formation of CdO hexagonal sheets with different thickness. Thicker sheets were obtained when urea and PVP were used. Chemoresistive devices consisting of a thick layer of CdO hexagonal sheets on interdigitated alumina substrates had been fabricated and their electrical and sensing characteristics were investigated. The sensor performances of the CdO sheets for carbon monoxide were reported. The results indicated that both the sensors exhibited high response and quick response-recovery dynamics. The sensing properties were explained in terms of rapid gas diffusion onto the sensing layer surface. © 2012 Elsevier B.V. All rights reserved. Source
