Numerical methods are not always convergent especially in higher velocities when shock waves are involved. A comparison analysis is performed to study the supersonic flow over conical bodies of three different cross sections circular, elliptic and squircle (square with rounded corners) shaped using  Perturbation techniques to find flow variables analytically. In order to find lift and drag forc...

Partial least square (PLS) analysis is the most favourite tool in chemometrics to develop calibration models. PLS technique allows us decipher even complex systems by analysing all variables instead of looking at them one a time. not only capture maximum variation associated with predictor (i.e. spectra) and predicted concentration) but also maximises correlation between them. The present artic...

In this paper, we study the mean square convergence of the kernel least mean square (KLMS). The fundamental energy conservation relation has been established in feature space. Starting from the energy conservation relation, we carry out the mean square convergence analysis and obtain several important theoretical results, including an upper bound on step size that guarantees the mean square con...

in this paper, three dimensional (3d) static and dynamic analysis of thick plates based on the meshless local petrov-galerkin (mlpg) is presented. using the kinematics of a three-dimensional continuum, the local weak form of the equilibrium equations is derived. a weak formulation for the set of governing equations is transformed into local integral equations on local sub-domains by using a uni...

Soil is a critical intermediary of water flux between precipitation and stream flow. Characterization of soil water content ( , m3 m 3) may be especially difficult in mountainous, snow-dominated catchments due to highly variable water inputs, topography, soils and vegetation. However, individual sites exhibit similar seasonal dynamics, suggesting that it may be possible to describe spatial vari...

background: association between the vitamin d deficiency and metabolic syndrome (mets) has previously been noted and reported to be controversial. the aim of this study was to determine the association of serum 25 (oh) d level and vitamin d dietary intake with mets among iranian population . methods: this analytical study was conducted on 122 patients with mets based on the atpiii criteria and ...

The Larsemann Hills (69°24'5, 76°20'E), situated on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica, consist of a series oflow-Iying, rocky peninsulas and islands on the southern shore of Prydz Bay. This area (fig. 1), which extends over 200 km2, is ice-free during the summer and bestrewn with more than 150 freshwater lakes. In the 1990/91 and 1991192 austral summers, the op...

Finite-dimensional square-freeK-algebras have been completely characterized by Anderson and D’Ambrosia as certain semigroup algebras A ∼= KξS over a square-free semigroup S twisted by some ξ ∈ Z (S,K), a two-dimensional cocycle of S with coefficients in the group of units K∗ of K. D’Ambrosia extended the definition of square-free to artinian rings with unity and showed every square-free ring ha...
