In this paper we develop a new simple and effective isogeometric analysis for modeling thermal buckling of stiffened laminated composite plates with cutouts using level sets. We employ first order shear deformation theory to approximate the displacement field stiffeners plate. Numerical treatment trimmed objects, such as internal in terms NURBS-based presents several challenges, primarily due n...

In this paper torsion of hollow Poroelastic shaft with Elliptical section is developed. Using the boundary equation scheme. It looks for a stress function where satisfied Poisson equation and vanishes on boundary. It also analyzed stress function and warping displacement for the hollow elliptical section in Poroelastic shaft. At the end, the result of elastic and poroelastic shaft in warping di...

Handwriting originates from a particular copybook style such as Palmer or Zaner-Bloser that one learns in childhood. Since questioned document examination plays an important investigative and forensic role in many types of crime, it is important to develop a system that helps objectively identify a questioned document’s handwriting style. Here, we propose a computer vision system that can assis...

A number of widely used programming languages use lexically included files as a way to share and encapsulate declarations, definitions, code, and data. As the code evolves files included in a compilation unit are often no longer required, yet locating and removing them is a haphazard operation, which is therefore neglected. The difficulty of reasoning about included files stems primarily from t...

Heat transfer to a fluid passing through a channel filled with porous materials is the subject of this investigation. It includes the derivation of the temperature solutions in channels having different cross sectional geometries. Primarily, consideration is given to a modified Graetz problem in parallel plate channels and circular tubes. This presentation includes numerical features of the exa...

In this paper, numerical simulation for a two-dimensional viscous and incompressible flow past the elliptical airfoil is presented by Random Vortex Blob (RVB). RVB is a numerical technique to solve the incompressible, two-dimensional and unsteady Navier-Stocks equations by converting them to rotational non-primitive formulations. In this method, the velocity vector at a certain point can be cal...

We proposed a local one-sided rubber bulging method of metal tubes to evaluate various strain paths at an aimed portion and measured the forming limit strains place occurrence necking under biaxial deformation. Using this method, since is used give pressure from inner side tube, no sealing mechanisms were necessary unlike during hydraulic bulging. An opening was prepared in front die locally bu...

background: polymer gel dosimetry is still the only dosimetry method for direct measuring of threedimensional dose distributions. mri polymer gel dosimeters are tissue equivalent and can act as a phantom material. in this study the obtained isodose maps with pagat polymer gel dosimeter were compared to those calculated with egsnrs for singleshot irradiations of 8 and 18 mm collimators of gamma ...

Local contact interactions between sea ice floes can be modeled on the large scale by treating the pack as a two-dimensional continuum with granular properties. One such model, which has gained prominence, is the viscous plastic constitutive rheology, using an elliptical yield curve and normal flow law. It has been used extensively in ice and coupled ice–ocean studies over the past two decades....

We present a theoretical construction for closest-to-classical wave packets localized in both angular and radial coordinates and moving on a keplerian orbit. The method produces a family of elliptical squeezed states for the planar Coulomb problem that minimize appropriate uncertainty relations in radial and angular coordinates. The time evolution of these states is studied for orbits with diff...
