The Zienkiewicz–Zhu (ZZ) super-convergent patch recovery technique based on a node neighborhood configuration is used most widely for of the stress field finite element analysis. In this study, an improved ZZ using proposed. procedure in least-squares sense over that consists union elements surrounding under consideration. proposed provides more sampling points and improves performance standard...

What is heuristics? The methods of imagination that prepares for invention and discovery, by accepting all arguments are good if they can succeed in achieving the proposed goals. A principle deemed to be heuristic, therefore, when it considered not on basis truth supports but fact contributes wholly or partly realisation some project. In order compose a work, creator has certain number dominant...

Sprites are electrical discharges in the mesosphere powered by quasi-electrostatic field following a cloud-to-ground lightning stroke. They luminous structures with tendrils formed space charge wave high electric fields that ionizes atmosphere, excites optical emissions and leaves trail of enhanced densities electrons, negative positive ions. The duration streamers sprites is usually ∼1–10 ms. ...

Absolute fast converging phylogenetic reconstruction methods are provably guaranteed to recover the true tree with high probability from sequences that grow only polynomially in the number of leaves, once the edge lengths are bounded arbitrarily from above and below. Only a few methods have been determined to be absolute fast converging; these have all been developed in just the last few years,...
