Dynamic Relaxation is an explicit method that can be used for computing the steady state solution for a discretised continuum mechanics problem. The convergence speed of the method depends on the accurate estimation of the parameters involved, which is especially difficult for nonlinear problems. In this paper we propose a completely adaptive Dynamic Relaxation method in which the parameters ar...

geometrically nonlinear governing equations for a plate with linear viscoelastic material are derived. the material model is of boltzmann superposi¬tion principle type. a third-order displacement field is used to model the shear deformation effects. for the solution of the nonlinear governing equations the dynamic relaxation (dr) iterative method together with the finite difference discretizati...

2 Although multiple pulse and multi-dimensional NMR techniques permit generation of off-diagonal density matrix elements and observation of complex coherence transfer processes, eventually the density operator returns to an equilibrium state in which all coherences (off-diagonal elements of the density operator) have decayed to zero and the populations of the energy levels of the system (diagon...

We introduce a method for using dynamic light scattering to measure the frequency-dependent linear viscoelastic moduli of complex fluids. The technique exploits the fluctuation dissipation theorem, which relates the relaxation of thermal excitations of a probe particle to the viscoelastic properties of the surrounding medium. The relaxation of the thermal excitations of probe particles are dete...

this paper provides an overview of the results of research related to anxiety disorders within the context of learning disabilities. about 8% of the student population in iran suffers from learning disabilities (ld). most of the criteria for anxiety disorders in icd–10 or dsm–iv–tr can be applied reliably and validly in individuals with mild-to-moderate learning disabilities. besides the clinic...

results the results showed that compared to the control group, relaxation (23.2) and positive self-talk (21.25) treatment methods alone can reduce pms (p < 0.001). on the other hand, a combined (relaxation + positive self-talk) treatment method (13.75) was more effective in reducing pms compared to relaxation or positive self-talk alone. conclusions it seems that psychological therapy based on ...

Dynamic lot sizing problem is one of the significant problem in industrial units and it has been considered by  many researchers. Considering the quantity discount in  purchasing cost is one of the important and practical assumptions in the field of inventory control models and it has been less focused in terms of stochastic version of dynamic lot sizing problem. In  this paper, stochastic dyn...
