We prove the following. Let T = fT(t)g t0 be a bounded C 0-semigroup on a Banach space X and A its innnitesimal generator. Then <(A) < 0 if and only if sup t>0 jj t Z 0 e iii T()ddjj < 1; 8 2 R; 8x 2 X: In particular we obtain that a strongly continuous and exponentially bounded family of bounded linear operators U on X is uniformly exponentially stable if and only if the spectrum of the innnit...
where f ∈ L2(Ω). Let Th be a simplicial or convex quadrilateral triangulation of Ω. In C 0 interior penalty methods, we choose the discrete space Vh ⊂ H 1 0 (Ω) to be either a P` (` ≥ 2) triangular Lagrange finite element space or a Q` (` ≥ 2) tensor product finite element space associated with Th. By an integration by parts argument [4], it can be shown that the solution u of (1), which belong...
Little is known about the contribution of C-afferent fibres to chronic painful conditions in humans. We sought to investigate the role of C-fibres in the pathophysiology of pain and hyperalgesia in erythromelalgia as a model disease for chronic pain. Erythromelalgia is a condition characterized by painful, red and hot extremities, and patients often report tenderness on walking. We made microne...
It is well-known that the harsh operational conditions of turbine blades lead to a gradual change in the microstructure of underlying Ni-based superalloy of blades. According to this, a rejuvenation process should be conducted on turbine blades superalloys to recover their microstructures. The first and main step of rejuvenation process is the determination of appropriate solution condition in ...
