Selection of machining conditions for improved performance characteristics has great importance during wire EDM, because numerous control factors contribute during machining. In the present study an attempt has been made to find the optimal machining conditions for multi performance characteristics simultaneously by applying grey relational analysis using entropy measurement for which Taguchi b...

Environmental and Ecological issues call for the reduction in usage of cutting fluids in metal cutting industry. New techniques are being inquired to achieve this objective. Hard turning with minimum quantity lubrication is one such technique which can alleviate the pollution problems associated with cutting fluids. In the present work, vegetable oil based cutting fluids like castor oil, palm o...

In this paper, we introduce a generalization of frames called partial resolution squares. We are interested in constructing sets of complementary partial resolution squares for Steiner triple systems. Our main result is the existence of six complementary partial resolution squares for Steiner triple systems of order v which can be superimposed in a v × v array so that the resulting array is als...

in this paper, we propose space-time block codes based on constituent intersectant orthogonal designs. after channel model is formulated, we studied the space-time block codes from constituent intersectant orthogonal designs. at last we made simulations for the space-time block codes from complex orthogonal design and the space-time block codes from constituent intersectant orthogonal design to...

A set of anaerobic-anoxic-aerobic (A/O) bio-reactor system was used to treat domestic sewage mixed with landfill leachate and fecal sewage in Datansha Sewage Treatment Plant in Guangzhou China. The experiment investigated the optimal mixing proportion of treating landfill leachate, fecal sewage mixed with domestic sewage synchronously and the optimal running conditions for the removal efficienc...

With modernization and increase in the number of automobiles worldwide, the consumption of diesel and gasoline has enormously increased. In this experiment tri fuel concept was used according to that diesel and turpentine different proportion bled introduced in diesel engine and acetylene entre in the diesel engine through intake manifold in the diesel engine. Among the many process parameters,...

A novel algorithm is presented for adaptive eigennltering and for updating the singular value decomposition (SVD). It is an improvement upon an earlier developed Jacobi-type SVD updating algorithm, where now the exact orthogonality of the matrix of singular vectors/eigenvectors is guaranteed by storing a minimal factorization. This orthogonality property is known to be crucial for the numerical...

The MIG welding is one of the most popular welding techniques used in industries. This uses a consumable metal electrode. The input parameters in MIG welding play a significant role in deciding the weld quality, strength, cost and speed. Most of times manufacturer faces a problem to select optimum process parameters for a good quality weld. This paper tries to present the effect of different we...
