The present paper applies the Linear Arch Static Analysis (LASA), which models masonry material as unilateral, i.e., No-Tension in sense of Heyman, and Safe Theorem Limit to study spiral stairs. A comparison is made with a refined FE analysis same problem, obtained by means ANSYS Parametric Design Language (APDL). objective prove that LASA can be valid alternative other more complex numerical m...

Surface comparison and matching is a challenging problem in computer vision. While reparametrization-invariant Sobolev metrics provide meaningful elastic distances point correspondences via the geodesic boundary value problem, solving this numerically tends to be difficult. Square root normal fields (SRNF) considerably simplify computation of certain between parametrized surfaces. Yet they leav...

Design of a natural dry cooling tower has been accomplished in two sections: the design of heat exchangers and the numerical solution of flow through the tower. Heat exchanger (Heller type) has been simulated thermodynamically and then coupled with a computer program, which calculated the turbulent natural convection flow through the tower. The computer program developed for this purpose can be...
