The present paper is dedicated to the preconditioning of boundary element matrices in wavelet coordinates. We investigate the incomplete Cholesky factorization for a pattern which includes also the coefficients of all off-diagonal bands associated with the level-level-interactions. The pattern is chosen in such a way that the incomplete Cholesky factorization is computable in log-linear complex...

This paper introduces a formal method to model the level of demand on control when executing cognitive processes. The cost of cognitive control is parsed into an intensity cost which encapsulates how much additional input information is required so as to get the specified response, and an interaction cost which encapsulates the level of interference between individual processes in a network. We...

An efficient scheme is presented for the numerical calculation of hydrodynamic interactions of many spheres in Stokes flow. The spheres may have various sizes, and are freely moving or arranged in rigid arrays. Both the friction and mobility matrix are found from the solution of a set of coupled equations. The Stokesian dynamics of many spheres and the friction and mobility tensors of polymers ...

We consider a reaction-diffusion equation with Neumann boundary conditions and show that solutions to this problem may be obtained from a problem with periodic boundary conditions and equivariant under O(2) symmetry. We describe the solutions for Hopf bifurcation and mode interactions involving Hopf bifurcation, namely, steadystate/Hopf and Hopf/Hopf. Neumann boundary conditions constrain the s...

In the present study, influence of a uniformly moving impinging shock on resulting wave–turbulent boundary layer interaction is numerically investigated. The relative Mach number front travelling above flat-plate model varied between 0 and 2.3, while quasi-steady inflow conditions remained constant with 3. To quantitatively evaluate effect speed, well-known scaling method for length in flows wa...

Artificial intelligence and robotics technologies do not manufacture robots only for industrial use, but also healthcare, marketing, tourism accommodation industries where social interaction is prevalent. Service are that interact directly with individuals to fulfill the physical, cognitive, emotional needs of individuals. Recently, it was observed number studies on employment in education has ...
