|We are often required to generate a Delaunay mesh whose element size is within a constant factor of a control spacing function, i.e., well-conformed, in addition to the fact that each mesh element has small aspect ratio, i.e., well-shaped. However, generating wellshaped Delaunay meshes is an open problem for a long time. Observe that slivers have small radius-edge ratio thus the Delaunay trian...

In SINP-TOKAMAK [an iron-core device having major radius = 30 cm, minor radius = 7.5 cm and B(toroidal) = 2 Tesla(maximum)] both high/normal q and very low q (VLQ) regimes can be achieved. Recently in this machine fast edge biasing experiment in the later regime revealed a change in plasma current profile at edge region leading to better confinement and longer duration of plasma current. The co...

Titanium and nickel alloys represent a significant metal portion of the aircraft structural and en components and the residual stresses induced by machining are very critical due to safety sustainability concerns. This paper presents experimental investigations and finite element simulat on turning of Ti–6Al–4V titanium alloy and IN100 nickel based alloy with uncoated and TiAlN co tools. Face t...

Centrifugal atomization of metal melts is a cost-effective process for powder production and spray deposition. The properties of the as-produced powder and deposit are determined primarily by the characteristics of the atomized droplets, which in turn are largely dependent on the flow development of the melt on the atomizer. This paper develops a model for analysing the flow development of a fu...

an injective map f : e(g) → {±1, ±2, · · · , ±q} is said to be an edge pair sum labeling of a graph g(p, q) if the induced vertex function f*: v (g) → z − {0} defined by f*(v) = (sigma e∈ev) f (e) is one-one, where ev denotes the set of edges in g that are incident with a vetex v and f*(v (g)) is either of the form {±k1, ±k2, · · · , ±kp/2} or {±k1, ±k2, · · · , ±k(p−1)/2} u {k(p+1)/2} accordin...

A range assignment to the nodes in a wireless ad hoc network induces a topology in which there is an edge between two nodes if and only if both of them are within each other’s transmission range. The critical transmission radius for -connectivity is the smallest such that if all nodes have the transmission radius , the induced topology is -connected. In this paper, we study the asymptotic criti...
