We study the deterministic dynamics of single-domain ferromagnetic nanoparticles in a viscous liquid induced by joint action gradient and uniform magnetic fields. It is assumed that field depends on time harmonically has two components, perpendicular parallel to one. also assume anisotropy so strong nanoparticle magnetization lies along axis, i.e., vector "frozen" into particle body. With these...

This special issue of The European Journal of Control is dedicated to some of the results of the European Community Esprit LTR Project VHS Veri cation of Hybrid Systems It consists of papers dealing with various aspects of one of the case studies treated in the project the Experimental Batch Plant at the university of Dortmund Before presenting the papers themselves it is worthwhile to say some...

Rotational smoothing is a phenomenon consisting in gain of regularity by means averaging over rotations. This present operators that regularize only certain directions, contrast to regularizing all directions. The the result rotating directions where corresponding operator performs effect. In this paper we carry out systematic study rotational for class includes k-vector-space Riesz potentials ...

Coherent drift modes and drift wave turbulence is studied in a collisionality dominated high-density helicon plasma. The drift wave instability is identified by comparison of the drift mode density fluctuations characteristics with a linear dispersion relation, which reproduces the experimentally observed bent eigenmode structures due to radial gradients of the collisionality profile. Special a...

Needham (1928) first noted the ‘drift’ of aquatic insects when examining the importance of terrestrial insects as trout food. When using a fine copper wire-meshed net to collect benthos in streams near Ithaca, NY he discovered large numbers of aquatic insects present his samples. Drift attracted more attention from researchers in the 1950’s after Muller quantified drift and compared drift with ...
