Barley can be cultivated and gives better yields in a large number of environments under various fertilization practices. This experiment was conducted two growing seasons 2018/2019 2019/2020 rainfall condition. Four new introduced cultivars barley (Arta, Tadmor, Clipper Furat2) along with commonly grown (Local-1 Local-2) were represented the current study; Soil (DAP) foliar treatments also inv...

We consider the hydrodynamic limit of a collisionless and non-diffusive kinetic equation under strong local alignment regime. The local alignment is first considered by Karper, Mellet and Trivisa in [24], as a singular limit of an alignment force proposed by Motsch and Tadmor in [32]. As the local alignment strongly dominate, a weak solution to the kinetic equation under consideration converges...

Melting is a major step in plasticating single screw extrusion, but most of the existing phenomenological know how was gathered by performing Maddock-type experiments with homopolymers. Given the current widespread industrial use of polymer blends, it is worth determining whether the same mechanisms and mathematical models apply, or whether different sequences develop. This work reports the res...

There is widespread recognition of the growing importance of universities in a knowledge society and a competitive economy, and of their required role in stimulating growth through University-Industry-Government interaction. As Tadmor (2003, p.22) put it "[universities] can show the way, offer the solutions and produce the hardware to resolve the most crucial problems". While the education and ...

We develop a simple energy method for proving the stability of finite difference schemes for multidimensional hyperbolic initial-boundary value problems. In particular, we extend to several space dimensions and to variable coefficients a crucial stability result by Goldberg and Tadmor for Dirichlet boundary conditions. This allows us to give some conditions on the discretized operator that ensu...

The high-order accuracy of Fourier method makes it the method of choice in many large scale simulations. We discuss here the stability of Fourier method for nonlinear evolution problems, focusing on the two prototypical cases of the inviscid Burgers’ equation and the multi-dimensional incompressible Euler equations. The Fourier method for such problems with quadratic nonlinearities comes in two...

In this thesi...

We introduce new Godunov-type semidiscrete central schemes for hyperbolic systems of conservation laws and Hamilton–Jacobi equations. The schemes are based on the use of more precise information about the local speeds of propagation and can be viewed as a generalization of the schemes from [A. Kurganov and E. Tadmor, J. Comput. Phys., 160 (2000), pp. 241–282; A. Kurganov and D. Levy, SIAM J. Sc...

We are concerned with an isothermal model of viscous and capillary compressible fluids derived by J. E. Dunn Serrin (1985), which can be used as a phase transition model. Compared the classical Navier-Stokes equations, there is smoothing effect on density that comes from terms. First, we prove global solutions critical regularity have been constructed in [11] second author B. Desjardins (2001),...
