The inhibitive effect of N, N-Bis (2-Chloroethylaminobenzaldehyde) ethylthiosemicarbazone (BCETSC) on the corrosion of mild steel in 1N H2SO4 was investigated by weight loss method, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM). The results showed that the inhibition efficiency increases with increase in concentration of the inhibitor. The potentiodynamic polarization curves revealed that BCETSC is a mixed type inhibitor in 1N H2SO4. EIS plots indicated that the addition of BCETSC increases the charge-transfer resistance of the corrosion process, and hence the inhibition performance. Scanning electron microscope (SEM) showed that the inhibition occurs due to adsorption of BCETSC molecules at the metal/solution interface. The free energy change value indicated that adsorption of BCETSC molecule is a spontaneous process and it adsorbs physically on mild steel surface.Keywords

A barcode is an optimal machine-readable representation of data relating to the object to which it is attached. Encoding data using barcodes enables a significant decrease of work in comparison with the amount of work involved when data is entered manually. In this paper, a high capacity color two dimensional barcode uses the colors to increase the barcode data density. This is proposed by encoding data in individual color channels. Data encoded in cyan, magenta, and yellow channels are estimated from red, green, and blue sensor channels of a scanner, respectively. Data is encoded by modulating the orientation of elliptically shaped dots. The orientation based data encoding provides beneficial robustness against printer and scanner tone variations. By encoding data in individual color channels, the capacity of color barcode is increased. The color interferences are avoided by using error correction methodology. The security is involved through modify extraction of geometric distortion signature from a printed barcode, which can be used to identify the type of source printer. User can view the data from the color barcode by using their mobile phones.Keywords

Image compression addresses the problem of reducing the amount of data required to represent a digital image. The underlying basis of the reduction process is the removal of redundant data. 4D-DCT video compression is an extension of the 3D-DCT image compression. 3D-DCT video compression method is an extension of the 2D-DCT image compression (e.g., JPEG). This algorithm takes a full-motion digital video stream and divides it into 8 groups of 8 frames. Each frame in the image is divided into 8×8 blocks (like JPEG), forming 8×8×8×8 frames. Each of it is then independently encoded using the 4 D-DCT algorithms:4D-DCT and Quantizer. 4D-DCT video compression is as novel method of image compression which gives a compression ratio better than the existing 3D-DCT technique. Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the image to an unacceptable level and giving a better compression ratio in terms of performance. The reduction in file size allows more images to be stored in a given amount of disk or memory space. It also reduces the memory space required for images to be sent over the Internet or downloaded from Web pages or across the borders for military applications.Keywords

The navigation, guidance and control (NGC) system of Reusable Launch Vehicle – Technology Demonstrator (RLV-TD) is the most complex system ever flown in ISRO’s launches. It includes a navigation system employing traditional inertial navigation system along with global positioning system aiding and radar altimeter, ceramic servo accelerometer package, angle of attack-based control, different control systems, including secondary injection thrust vector control, reaction control system and aero control surfaces. Closed loop simulations of integrated NGC system of RLV-TD are of utmost importance to ensure mission success by assessment of system performance in nominal and off-nominal flight conditions. Validation is achieved through progressive evaluations in different levels of integrated simulation, namely autonomous simulations, software in loop simulation, on-board processor in loop simulation, hardware in loop simulation and actuator in loop simulation using Iron Bird test facility. This article discusses the overall NGC system, challenges faced during the realization of the simulation test bed, including system design to validate the new on-board elements, commissioning of Iron Bird facility and validation through various phases of simulation. The outcome of these simulations played a crucial role in bringing about improvements and helping in the evolution of the on-board system to the final configuration, ensuring the success of the mission.Keywords

Transaction costs (TC) are the costs involved in making an economic exchange. It includes search and information costs, bargaining costs and policing and enforcement costs. This study mainly focused on estimation of comparative transaction cost incurred in availing the Governmental benefits by the Scheduled Castes and Scheduled Tribe (SC/ST) farmers in hilly zone of Karnataka. A sample of 35 SC/ST farmers from GramPanchayaths of Good Governance (GpGG) and Gram Panchayaths of Modest Governance (GpMG) of Sakleshpur Hassan district of Karnataka had chosen for analysis. The results revealed that the benefits received by SC/ST farmers fromGovernmental programmes by GpGG farmer is Rs. 17356, by participating in 8 governmental programmes and GpMG farmer gain Rs. 10764 by participating 6 Governmental programmes.The average transaction cost of Rs. 304 per programme was spent in GpGG, whereas Rs. 307 per programme was paid in GpMG. For every rupee of transaction cost incurred, the total benefit from governmental programmes increased by Rs. 2.8. The percentage of transaction cost varies from programme to programme (one to thirty three %). The opportunity cost of labour accounts to 32 per cent of in GpGG whereas it is higher in GpMG 37 per cent. Expenditure incurred in obtaining documents in both the Governance is at par that is 33 to 34 per cent, whereas rent paid exclusively to avail the benefits is comparatively higher in GpGG (35%) than GpMG (29%). Irrespective ofGovernance the transaction cost remains constant. Panchayath Raj should be well Governed to reduce the transaction cost and inclusion and exclusion errors.Keywords
