This study discusses the application of Taguchi method in assessing minimum entropy generation and maximum heat transfer rate for natural convection in an enclosure embedded with isothermal cylinder. The simulations were planned based on Taguchi’s L25 orthogonal array with each trial performed under different conditions of position and aspect ratio (AR) of the cylinder. The thermal lattice Bolt...

We review recent progress in calculating kaon spectrum, pseudoscalar meson decay constants, B K , ε ′ /ε, K → ππ matrix elements, kaon semileptonic form factors, and moments of kaon distribution amplitudes on the lattice. We also address the issue of how best to improve the staggered fermion formulation for the action and operators.

We calculate semileptonic form factors for the decays Bc→ ηc lν and Bc→ J/ψ lν over the entire q2 range, using a highly improved lattice quark action for charm at several lattice spacings down to a = 0.045 fm. We have two ways of treating the b quark: either with an O(αs) improved NRQCD formalism or by extrapolating a heavy mass mh to mb in the relativistic formalism. Comparison of the two appr...

The suffix tree data structure has been intensively described, studied and used in the eighties and nineties, its linear-time construction counterbalancing his spaceconsuming requirements. An equivalent data structure, the suffix array, has been described by Manber and Myers in 1990. This space-economical structure has been neglected during more than a decade, its construction being too slow. S...

This study investigated the optimization of three welding parameters (wire feed speed, arc voltage, and shielding gas flow rate) for SS 304H by using Taguchi based Grey relational analysis. In this research work, pure argon was used as shielding gas. Numbers of trials were performed as per L16 (4xx3) orthogonal array design and the mechanical quality such ultimate tensile strength, microhardnes...

Thinning array antennas have become one of the best approaches towards minimizing side lobes and achieving required FNBW SLL. Unlike all element arrays, thinning systematically removes some fraction elements activates remaining to obtain intended pattern without degrading performance antenna array. An evolutionary algorithm is gaining growth in providing better optimization solutions than other...

A Side Lobe Canceller (SLC) structure is a conventional partially adaptive technique which is used in large adaptive array radars. If a desired signal has long time duration in comparison with the SLC adaptation time, signal components may be cancelled. So, this paper presents a modified SLC which eliminates desired signal cancellation problems and allows using an unconstrained adaptive algorit...
