We describe the gravitational degrees of freedom of the Schwarzschild black hole by one free variable. We introduce an equation which we suggest to be the Schrödinger equation of the Schwarzschild black hole corresponding to this model. We solve the Schrödinger equation explicitly and obtain the mass spectrum of the black hole as such as it can be observed by an observer very far away and at re...

Two parts, each with two holes, are to be pinned together by some type of fastener. Nominally the holes on part 1 are to match the holes on part 2 and the fastener diameters should be smaller than the hole diameters. Due to variation in hole diameters, fastener diameters and hole center positions loose pinning of the two parts may no longer be possible. The problem considered here is to define ...

In the present work, the edge stretchability of advanced high strength steel (AHSS) was investigated experimentally and numerically using both a hole expansion test and a tensile specimen with a central hole. The experimental fracture strains obtained using the hole expansion and hole tension test in both reamed and sheared edge conditions were in very good agreement, suggesting the tests are e...

13  Abstract-In this study, the wok is carried out to analyzed, the stresses of plate with oblique hole with the Finite Element Analysis. Stress analysis of a series of flat plates with oblique holes subjected to axial tension has been carried out using the finite element method (FEM). Different plate hole diameter-width ratios, angles of hole obliquity have been considered to provide stress c...

This paper presents a technique to expose and characterize nano-structured hole arrays in tapered photonic crystal fibers. Hole array structures are examined with taper outer diameters ranging from 12.9 microm to 1.6 microm. A combined focused ion beam milling and scanning electron microscope system was used to expose and characterize the arrayed air-silica structures. Results from this combine...

Filling holes of 3D models is an important and complicated process. In this paper, we introduce a new and robust method for filling complex holes in triangular mesh models. In order to fill separate holes, the boundary edges of a hole are smoothly arranged and then locally uniform new points are added to the hole. The new points are selected by minimizing a hole filling area. The Delaunay trian...

A hole is a chordless cycle with at least four vertices. A hole is odd if it has an odd number of vertices. A banner is a graph which consists of a hole on four vertices and a single vertex with precisely one neighbor on the hole. We prove that a (banner, odd hole)-free graph is either perfect, or does not contain a stable set on three vertices, or contains a homogeneous set. Using this structu...

We present numerical calculations of the plasmon properties of single-hole and hole-pair structures in optically thin gold films obtained with the Green’s tensor formalism for stratified media. The method can be used to obtain the optical properties of a given hole system, without problems associated with the truncation of the infinite metal film. The calculations are compared with previously p...

We discuss some puzzles on the identity of black hole entropy by using the Landauer’s principle of information erasure. Especially, we discuss the information freezing on the black hole horizon in terms of information erasing process. We also calculate the quantized black hole mass spectra and entropy assuming that the black hole processes information in unit of bit. The black hole entropy gain...

Security is an important need in wireless mesh networks to give safe and shared information between wireless non-static nodes. In wireless network nodes has ability to act correctly and route the packets. Wireless mesh networks unusual method of producing,keeping and sharing information ability of mobile objects to show spontaneous and cheap adjusting arrangement itself.There are different type...
