The paper shows ICPET-SA activity results in the thermopower equipment and installations rehabilitation and repowering field: steam boilers, electrotatic precipitators, steam turbines, electrical generators and burning systems for industrial furnaces.
A high accuracy difference method (hermitian method) for the solution of evolution equations of parabolic type is presented. Its most original feature is to use several unknowns (the value of the solution and its spatial derivatives) at every nodal point of the computational grid. It is shown that this method has better computational performance than classical schemes on non-uniform and coarse meshes.
This paper presents a general formulation for frame analysis based on ‘lumped dissipation models’ and continuum damage mechanics. A particular model for RC frames based on this framework is proposed and the numerical implementation of simplified damage models in commercial finite element programs is described.
In this paper, we use the upper and lower solutions method to show that there existsa λ*, such that the nonlinear functional difference equation of the form χ(n + 1) = a(n)χ(n) + λh(n)ƒ(χ(n − τ(n))), n ε Z, has at least one positive T-periodic solutions for λ ε (0, λ* and does Buy Cheap Ghd Online Uk
not have any positive T-periodic solutions Ghd Hair Uk Outlet
for λ > λ*, where a(n), h(n), and τ(n) are T-periodic functions.
