	Studie integrálního uspořádání magnetohydrodynamického čerpadla pro transport roztavených kovů či solí Kotlan, V. ; Doležel, Ivo ; Ulrych, B. The paper deals with one of the fundamental possibilities of improving magnetohydrodynamic (MHD) pumps based on the integration of effects of elementary MHD minipumps distributed along the pipe through which they transport the considered liquid. The crucial point of the work consists in computer modeling of this integral arrangement (system of minipumps) and presentation of the results that demonstrate their advantages–reduction of electric currents flowing through the minipumps and consequent reduction of the total ohmic losses in the system.

	Studie vhodného uspořádání magnetických obvodů pro realizaci magnetokalorického efektu Doležel, Ivo ; Ota, J. ; Ulrych, B. The paper is stimulated by one of very prospective physical do-mains – magnetic cooling based on the magnetocaloric effect. Successful realization of this effect requires a magnetic circuit with permanent magnets producing very strong and uniform magnetic field and the paper deals with arrangements of such circuits. Its crucial point consists in the presentation and consequent discussion of the results that allow estimating the suitability of the considered magnetic circuits. Detailed record
	Statické charakteristiky konstrukčních částí řiditelného termoelastického aktuátoru Doležel, Ivo ; Kotlan, V. ; Ulrych, B. The paper deals with one of the basic conditions of practical employment of finely controllable thermoelastic actuators – problems of the static characteristics of its individual structural parts. It contains the formulation of the principle of such thermoelastic actuators, description of its components (a dilatation element heated by induction, auxiliary electromagnetic actuators, and self-locking friction clutches) and their mathematical models. Briefly discussed are also their corresponding computer models making use of the finite element method. The crucial point of the work consists in the presentation of the results – static characteristics of the considered structural parts of the controlled thermoelastic actuators. Detailed record
