Vladimír Daněk,Raino Mäkinendamping introduced by the joints is often observed to depend nonlinearly on amplitude. Although models for individual joints have been employed with some success, the modeling of a structure with many joints remains a significant obstacle. This work explores whether nonlinear damping can be applied

A mathematical model and an existence theory for non-isothermal phase separationhase transitions and non-equilibrium thermodynamics. It consists of a system of nonlinear parabolic differential equations for the order parameter and the energy as conserved quantities. The model is conformable with the first principles of thermodynamics. Besides a description of the model we study

Stability of Thermocapillary Convection in Float-Zone Crystal Growthonditions under which the flow will be stable under . perturbations. In earlier work axisymmetric disturbances have been considered while the onset of buoyancy-driven convection in a cylinder heated from below has served as a test case for the three-dimensional problem. Here, initial results will b

Numerical solution of coupled Navier-Stokes and Stefan equationsof their solutions are considered. An iterative method to solve nonlinear equation is proposed. In the method at each iteration step the solution of corresponding linear problem is obtained by means of finite element technique. Estimates for the rate of convergence of the approximate solution to the

On approximation of the inverse one—phase Stefan problemsystem is considered only on a domain delimited by the desired moving boundary. The necessary conditions for optimality are established and a descent algorithm is derived. Its numerical implementation for bang-bang suboptimal controls is presented; particular attention is devoted to find a starting

Penalties and Mixed Finite Element Analysis for Variational Inequalitiesonal problem. On the other hand these auxiliary problems need a further numerical method for its solution. Penalty methods form a useful tool but the arising parameters have to be adjusted in a proper way. In the present paper we discuss as well discretization by finite elements as parameter selecti

Semi-analytical investigation of unsteady free-boundary flowsication by M. Van Dyke. They are mainly the methods of processing the series and sequences. This group comprises the well-known algorithms based on the Padé approximants and continuous fractions as well as convergence acceleration algorithms, Domb-Sykes test, etc. The author uses this technique to i
