We discuss a new optimisation for recursive functions yielding multiple results in tuples for lazy functional languages, like Clean and Haskell. This optimisation improves the execution time of such functions and also reduces the amount of memory allocated in the heap by these functions, which reduces garbage collection costs. In some cases execution time is improved by more than a factor of tw...

This paper presents a physical approach to simulate objects deformation in images. To physically model the given objects the finite element method is used, and to match the objects’ nodes modal analysis is considered. The desired displacement field is estimated through the dynamic equilibrium equation. To solve this differential equation different integration methods can be used. In this paper ...

linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the canine respiratory system (final host). the discharged eggs infect many plant feeder animals including human causing visceral and nasopharyngeal linguatulosis which is known as “marrara syndrome”. in current study, the prevalence of infection with l. serrata nymphs in mesenteric lymph nodes (...

Many researchers content themselves with the 2D simulation of welding process instead of the 3D simulation, because of the time and the cost factors of the latter. In this research, the number of elements and nodes are reduced by an initiative plan (defining an equivalent model) for the simulation of welding. The welding process has been simulated by an uncoupled thermal-mechanical finite eleme...

Immune system plays crucial role in body and lymph nodes are essential parts of this system for combating pathogens. However, no study has ever been conducted on morphometric development of sheep lymph nodes in fetal period. Thus, this study attempted to examine the morphometric characteristics of a number of important lymph nodes of some lymphocenters of sheep during fetal period. To this end,...

In this article, element free Galerkin method is used for static analysis of thin micro/nanoscale plates based on the nonlocal plate theory. The problem is solved for the plates with arbitrary boundary conditions. Since shape functions of the element free Galerkin method do not satisfy the Kronecker’s delta property, the penalty method is used to impose the essential boundary conditions. Discre...

The following article presents the elaboration and results obtained from a 3D finite element, of 8-node hexahedron type with 6 degrees freedom (DOF) per node (48 DOF element) based on third degree Hermitian polynomials, 2-node structural (12 element), polynomials theory Timoshenko for beams. This has two purposes; first one is formulation element capable capturing bending effects, second to ver...

A new simple and accurate four-node quadrilateral element is developed for linear static and dynamic analysis of thin to moderately thick laminated, anisotropic plate/shell structures within the first-order shear deformation theory (FSDT). The element is built by incorporating the strain smoothing method of mesh-free conforming nodal integration into the conventional bilinear four-node quadrila...

this research work is devoted to the development of a mathematical model for the simulation of the flow of polymeric melts through the die region of extruders. a set of governing equations are solved using finite element method. standard galerkin technique is used in conjunction with the mixed scheme to solve the flow equation. due to the non-linear nature of global equations, the picard iterat...
