Java Applications Monitoring Using JVM Tool Interface
Vomáčka, Pavel ; Dudka, Vendula (referee) ; Kočí, Radek (advisor)
This thesis deals with the design and implementation of an agent with a purpose to watch over the stack and over the heap with focus on localization of object allocation. This information is then shown in graphic user interface. A JVM TI interface is also described. Later parts of the thesis discuss the Java Virtual Machine and its important components with special attention to its memory management.

THE USE OF SINTERED ARTIFICIAL AGGREGATES PRODUCED FROM SOLID ENERGETIC WASTE FOR CONCRETE.
Batelka, Michal ; Stehlík, Michal (referee) ; Kolář,, Karel (referee) ; Cigánek,, Jindřich (referee) ; Adámek, Jiří (advisor)
This work deals with issues aimed at the possibility of treating the material which has not been used yet – coal tailings. The work includes among others the production, its optimalization and utilization of a new type of lightweight artificial aggregate in the process of production of concrete. The possibility of manufactured the artificial aggregate is dealt with the principle of self-burning of the raw material's batch at the agglomerative grate. The optimalization of the burning process was performed both with the homogenous and the layered batch. Further part of the work focuses on the fabrication of diverse types of concrete and determination of their parametres. This section is significantly extended with the comparison of basic physical and specific properities of the new type of concrete with those of the commonly produced types. The last part of presented work deals with the ecological - economic situation of these issues. The proposed solution points to the possibility of utilization of the coal tailings which are put to the tailings heaps. It was managed to optimize the burning process and to find the most convenient system for storing the raw material's batch at the agglomerative grate. Next, it was proved that the types of concrete produced with a new sort of aggregate are also suitable for fabricating the construction concrete with the strength above the border of 50 MPa, which are applicable even in harder conditions. These sorts of concrete also have a lower volume weight and very good bending properties. The major finding, which underlines the contribution of this work, is that the up to now unused material is suitable for fabrication of relatively high-quality and thermally stable aggregate of strength on the border of 5 MPa, which can be use for fabricating concrete with very good results even in this field. Another great contribution of this work can surely be the fact, that a preliminary economic balance of the manufacturing pr

Fibonacci heaps - their variations and alternative data structures
Melka, Jakub ; Koubková, Alena (advisor) ; Koubek, Václav (referee)
In this paper we explore Fibonacci heaps and their variants. The alternative versions of the Fibonacci heap, the thin and thick heaps, were introduced by H. Kaplan and R. E. Tarjan in 2008. We compare these heaps from both experimental and theoretical point of view and we also include some classic types of heaps, namely regular and pairing heap. In our experiments we will be most interested in the total time required to run an algorithm that works with heap. The results show that thin and thick heaps are usually faster than the Fibonacci heap and slower than the regular heap. In conclusion, we summarize the knowledge gained from experiments.
