In this paper, we study the problem of testing the conductance of a given graph in the general graph model. Given distance parameter ε and any constant σ > 0, there exists a tester whose running time isO( (1+σ)/2·logn·log ε ε·Φ2 ), where n is the number of vertices andm is the number of edges of the input graph. With probability at least 2/3, the tester accepts all graphs of conductance at leas...

An analytical procedure for the calculation of the inductance of planar zig-zag spiral inductors is proposed. The procedure is based on the partial inductance concept and models the inductor as a series of a number of parts. The self-inductance of each individual part, which has the shape of a parallelogram, and the mutual inductance between any two parts of the inductor are determined. The ind...

OUT understanding of the fundamental physical limits of information handling has developed along a very convoluted path. Most of the initially plausible physical conjectures have turned out to be wrong. A participant’s personal view of these events is not a disciplined contribution to the history of science. I do, however, last my own mistakes along with those of others.

We correct a mistake in [DK2] and use this to identify homotopy function complexes in a model category with the nerves of certain categories of zig-zags.

Let T = (V, F,E) be a 2-dimensional triangular tiling of R 2 in quad-edge representation [2], consisting of a set of vertices V , a set of faces F and a set of half-edges E. We say T is locally finite iff for any circle in R 2 it holds that the set consisting of all edges (vertices, faces) in T that intersect the circle (circumference or interior) is finite. Let e ∈ E be some half-edge of this ...

abstract in this study the possibility of utilizing date syrup as a sugar replacer in soft ice-cream was investigated. for this purpose control sample was formulated based on iranian ice- cream standard. data syrup which produced from third grade kabkab dates, replaced sucrose in four levels (25, 50, 75 and 100%). physical properties including overrun, viscosity and freezing point (drawing temp...

2014 By a formal expansion in gradient of the phase variable we obtain the equations governing the relaxation of zig-zags. The application has been developed for convection close to the threshold. We use an 03B5-expansion of the solution for the realistic case of no slip (rigid) velocity boundary conditions. We obtain : D~ = 03BE20/03C40 (03B4k/kc + F(Pr) 03B4Ra/Rac) where the numerical values ...

Zoster immune globulin (ZIG) can prevent clinical chickenpox in exposed, susceptible, normal chilthen.’ In a collaborative study2 in which 15 susceptible children at high risk received ZIG within three days following exposure, there were no deaths and only one child developed progressive vanicella. At that time, a mortality of 7% and a rate of progressive varicella of 30% were reported in simil...
