the effect of boundary conditions on the solution of the inverse problem of identifying the geometry and location of a cavity inside an elastic solid body using displacement measurements obtained from a tension test is investigated. the boundary elements method (bem) coupled with the genetic algorithm (ga) and the conjugate gradient method (cgm) are implemented in this identification problem. a...

finite and boundary element methods have been used by many authors to solve mathematicalphysics problems. however, the coupling of these two methods happens to be more efficient as it combinestheir merits. in this paper, the mathematical analysis of the coupling of finite and boundary element methodsfor the helmholtz equation is presented.

We develop a model based on the Dirichlet-compound multinomial distribution (CMD) and Ewens sampling formula to predict the fraction of SNP loci that will appear fixed for alternate alleles between two pooled samples drawn from the same underlying population. We apply this model to next-generation sequencing (NGS) data from Baltic Sea herring recently published by (Corander etal., , Molecular E...

India’s growing power demands and emission norms require more efficient coal-based plants. The shifting of plants from subcritical to ultra-supercritical (USC) steam conditions could improve efficiency by 12% reduce CO2 emissions 35%. There is a need develop qualify materials under with high temperatures pressures in laboratory scale. sample were exposed 700 °C air pressure at °C/243 bars for 1...

A gradient-index axicon with its initial focus offset from the back surface was designed with the thin-lens approximation. Two samples were fabricated by means of the time-varying boundary condition diffusion method, which is based on the modified quasi-chemical diffusion model. Intensity profile measurements were taken along the focal region of the axicons. The samples produced extended line f...

A prototype system for automated assessment of biscuit bake has been developed. The system employs monochrome imaging and histogramming techniques to classify product samples as underbaked, correctly baked or overbaked. Two products have been investigated. Product \A" exhibits uneven browing due to the formation of blisters. An intensity histogram suitably characterises the overall browning and...

We have developed a unique micromechanical method to extract extremely thin graphite samples. Graphite crystallites with thicknesses ranging from 10 to 100 nm and lateral size ,2 mm are extracted from bulk. Mesoscopic graphite devices are fabricated from these samples for electric field-dependent conductance measurements. Strong conductance modulation as a function of gate voltage is observed i...

Organic constituents of human saliva vary around 0.5 g. per 100 ml. depending on the nature of the stimulus and the hour of collection. Most of the organic matter is protein, with mucin being the preponderant component. However, it is one of the smaller protein elements that has been the most widely studied, mainly because of its enzymatic action, that is, salivary amylase. Phase boundary elect...

The aim of this study is to investigate the effect of boundary conditions on the accuracy and stability of the numerical solution of fluid flows in the context of single relaxation time Lattice Boltzmann method (SRT-LBM). The fluid flows are simulated using regularized, no-slip, Zou-He and bounce back boundary conditions for straight surfaces in a lid driven cavity and the two-dimensional flow ...
