Abstract The aim of this study is of the effect of structural changes in higher education on changes of output in Sistan and Baluchestan Province using structural decomposition analysis (SDA). The input-output tables of this region for the period 2006-2011 have been employed as the database of the model. The structural changes were decomposed into two factors: changes in share of specific sect...

This practice and experience paper describes a robust C++ implementation of several nonlinear solid 3D deformable object strategies commonly employed in computer graphics, named the Vega FEM simulation library. Deformable models supported include co-rotational linear FEM elasticity, Saint-Venant Kirchhoff FEM model, mass-spring system, and invertible FEM models: neo-Hookean, Saint-Venant Kirchh...

A new nematode species, Rhabdochona kharani sp. nov., has been isolated from the intestine, stomach and swim bladder of the fish Labeo gedrosicus Zugmayer, 1912 (Fam. Cyprinidae: Cypriniformes) from spring water at Garruk, District Kharan, Balochistan. The new species is characterized largely by the presence of eight anterior teeth in the prostom, inconspicuous deirids, by the shape and length ...

The radial Schrodinger equation for a spherically symmetric potential can be regarded as a one-dimensional classical harmonic oscillator with a time-dependent spring constant. For solving classical dynamics problems, symplectic integrators are well known for their excellent conservation properties. The class of gradient symplectic algorithms is particularly suited for solving harmonic-oscillato...

Hyper-sensitivity to unknown boundary conditions plagues indirect methods of solving optimal control problems as a Hamiltonian boundary-value problem for both state and costate. Yet the hyper-sensitivity may imply manifold structure in the Hamiltonian flow, knowledge of which would yield insight regarding the optimal solutions and suggest a solution approximation strategy that circumvents the h...

Muscle contractions that load in-series springs with slow speed over a long duration do maximal work and store the most elastic energy. However, time constraints, such as those experienced during escape and predation behaviours, may prevent animals from achieving maximal force capacity from their muscles during spring-loading. Here, we ask whether animals that have limited time for elastic ener...

Multiple inheritance is a difficult and complex feature added to C# at release 2.0. Cargill argues that the addition was a step backward in that the feature adds complexity to the language without adding functionality. His basis for the latter half of this claim is that no example of multiple inheritance has been given which cannot be rewritten into a functionally equivalent example which uses ...

In recent years a number of red-blood-cell (RBC) models have been proposed using spring networks to represent the RBC membrane. Some results predicted by these models agree well with experimental measurements. However, the suitability of these membrane models has been questioned. The RBC membrane, like a continuum membrane, is mechanically isotropic throughout its surface, but the mechanical pr...

‎In this paper a nonlinear backward parabolic problem in one‎ ‎dimensional space is considered‎. ‎Using a suitable iterative‎ ‎algorithm‎, ‎the problem is converted to a linear backward parabolic‎ ‎problem‎. ‎For the corresponding problem‎, ‎the backward finite‎ ‎differences method with suitable grid size is applied‎. ‎It is shown‎ ‎that if the coefficients satisfy some special conditions‎, ‎th...
