Modelování THM procesů v horninách
Blaheta, Radim ; Kohut, Roman ; Neytcheva, M. ; Starý, Jiří
This paper is devoted to medelling thermal (T), hydraulic (H) and mechanical (M) processes in rocks.These physical processes seem to be most important ones for many engineering applications ranging from the classical mining, tunelling and underground constructions to new geotechnologies of waste disposal or geothermal anergy utilization.

Poslední trendy v paralelním programování
Jakl, Ondřej
The paper gives a survey on current approaches and trends in programming parallel systems, paying special attention to scientific and high-performance computing. The mainstream tools (libraries, languages, products) for systems with shared and distributed memory are characterized and some novelties like parallel Matlab are introduced.

O limitní přesnosti segregovaných technik pro sedlobodové úlohy
Jiránek, P. ; Rozložník, Miroslav
In this contribution, we analyze the numerical behavior of the Schur complement reduction method and the null-space projection method – two representatives of segregated methods used to solve large- scale saddle point systems. They are both based on the transformation of the original problem to the reduced form which is solved iteratively (e.g. by the conjugate gradient method) giving approximations to one block component of the solution vector. The remaining unknowns are solved by the back-substitution to the original system. Depending on the actual implementation, we estimate the maximum attainable accuracy level of the computed approximate solution.
