permanent facial paralysis is a catastrophic event for involved patients. in long lasting paralysis with severe facial muscles atrophy, masseter muscle transfer is a very good choice. but its greatest problem is postoperative elongation of flap and gradual diminishing of early results and loss of symmetry. this article advocate a new modification for resolving this problem with concomitant elev...

We study the scaling behaviour of thin martensitic films. Specifically we consider an elastic energy with two SO(3) invariant wells which are strongly incompatible in the sense of Matos and Šverák, but whose two-dimensional projections are compatible. We show that in a thin film of thickness the energy per unit height scales like h. This scaling lies in between the classical membrane theory (wh...

By increase in the power of computer systems and enhanced power of the components and their temperature, including the central processing unit (CPU), cooling just by the air is not effective and there is need for more powerful systems to cool down and increase the power of the cooling system. In this article simulation of the heat exchanger material of the fluid cooling system has been studied ...

In the present study, natural convective heat transfer in a partitioned square cavity utilizing nanofluids is studied. The vertical left and right walls are considered as the hot and cold walls, respectively and the partitions assumed to be adiabatic. The nanofluid used in this study is Al2O3 with the volume fraction of 20%. It is assumed that nanofluid is a single phase f...

Abstract Phase change material (PCM) is considered as one of the most effective thermal energy storage (TES) systems to balance supply and demand. A key challenge in designing efficient PCM-based TES lies enhancement heat transmission during phase transition. This study numerically examines privilege employing twisted-fin arrays inside a shell-and-tube latent unit improve solidification perform...

In this paper, we present a new terrain rendering approach, with adaptive triangulation performed entirely on the GPU via tessellation unit available on the DX11-class graphics hardware. The proposed approach avoids encoding of the triangulation topology thus reducing the CPU burden significantly. It also minimizes the data transfer overhead between host and GPU memory, which also improves rend...

An important problem in analytic and geometric combinatorics is estimating the number of lattice points in a compact convex set in a Euclidean space. Such estimates have numerous applications throughout mathematics. In this note, we exhibit applications of a particular estimate of this sort to several counting problems in number theory: counting integral points and units of bounded height over ...

objectives: fracture strength is an important factor influencing the clinical long-term success of implant-supported prostheses especially in high stress situations like excessive crown height space (chs). the purpose of this study was to compare the fracture strength of implant-supported fixed partial dentures (fpds) with excessive crown height, fabricated from three different materials. mater...
