This paper studies the issue of determination and influence natural boundary conditions in problem buckling a thin plate with an elliptical inclusion under tension. First, naturalness “free edge” type for hole is proved. Then welded considered are derived. The limit cases checked absolutely soft rigid one. It shown that first case leads to corresponding conditions, second case, absence since cl...

We investigate behavior of the stress tensor in the vicinity of elliptical hole cut-out from elastic material stretched on opposite sides by constant force. We perform the analysis on the linearized elastic model first with constant material coefficients and then with material coefficients depending on the concentration of diffusing fluid. In our model elastic coefficients are shrinking with in...

the rapid melting of a semi- infinite body due to the absorption of a cw laser beam radiation has been studied. the enthalpy technique for the solution of phase change problems has been used in an explicit finite difference form to calculate the transient temperature distribution in the semi-infinite body and the growth rate of the melt pool. the technique has been modified so that it is not ne...

background and objectives: probiotic yeasts are used in production of functional foods and pharmaceutical products. they play an important role in promoting and maintaining human health. until now, little work has been published on improving the survival of saccharomyces in stimulated gastrointestinal condition. material and methods: in this study the exposure of the yeast in the capsulate and ...

Subsuns, Bottlinger's rings, and elliptical halos are simulated by the use of a Monte Carlo model; reflection of sunlight from almost horizontal ice crystals is assumed. Subsuns are circular or elliptical spots seen at the specular reflection point when one flies over cirrus or cirrostratus clouds. Bottlinger's rings are rare, almost elliptical rings centered about the subsun. Elliptical halos ...

the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...

We have finalized the old (1979) results from [11] about enumeration of connected components of moduli or real polarized K3 surfaces. As an application, using recent results of [13] (see also math.AG/0312396), we completely classify real polarized K3 surfaces which are deformations of real hyper-elliptically polarized K3 surfaces. This could be important in some questions, because real hyper-el...
