Evidence for Modality-Specific Processes in Approximate Numerical Comparison

It has been claimed that a genuinely abstract number representation exists and is capable of representing the numerosity of any set of discrete elements irrespective of whether they are presented in visual or auditory modality. To test whether adults can compare large numerosities crossmodally as accurately as intra-modally, we measured Weber fractions and a point of subjective equality of nume...

Numerical modelling of microforming processes

It is well recognized that expertise, experience, and theoretical knowledge available in conventionally sized metal forming cannot be simply transferred to microforming. This is due to so-called size effects which have distinct effect on material flow, friction and other process characteristics [1,2]. Today, process simulation is a standard tool in industry, applied to support process layout an...

Numerical Comparison of Controls

We provide two approaches to the numerical analysis of stochastic control problems. These analyses rely on linear programming formulations of the control problem and allow numerical comparison between controls and numerical veriication of optimality. The formulations characterize the processes through the moments of the induced occupation measures. We deal directly with the processes rather tha...

Numerical Modelling of Transport Processes in Semiconductors

The peculiarities of electric current in semiconductors with nonuniform distribution of charge carriers are studied. The semiclassical drift-diffusion equations consisting of the continuity equations and the Poisson equation are solved numerically using Rusanov finite-difference scheme of third order. The different types of boundary conditions are numerically investigated. It is shown that the ...
