Information System Design
Steklý, Tomáš ; Svoboda, Jiri (referee) ; Koch, Miloš (advisor)
Diploma thesis deals with the design of the information system for the financial department of the company of Kiwi.com. Target of the work is to evaluate the current status of the information system of the financial department and to analyze its lacks and weaknesses. Based on these analysis and requirements will be determined the design of the new information system. Final part of the diploma thesis will be dedicated to the benefits and economical evaluation of the designed measures.
Transmission and detection of the crayfish plague pathogen under experimental conditions
Svoboda, Jiří ; Petrusek, Adam (advisor) ; Fiala, Ivan (referee)
The crayfish plague pathogen, Aphanomyces astaci, is one of the most serious threats to European indigenous crayfish species, e.g., the noble crayfish (Astacus astacus). The only way to protect susceptible crayfish species from the disease is to prevent the dispersion of the pathogen to their populations. One of the most important sources of the crayfish plague pathogen in Central Europe is the spiny-cheek crayfish (Orconectes limosus), a species of North American origin, which can carry the parasite in its cuticle for years. Some literature sources claimed that the pathogen dispersion from the American vectors is restricted to periods of moulting or to the time before and after the crayfish death. However, experimental evidence for such hypotheses was lacking. The main aim of my thesis was to test these predictions, and the alternative scenario that the crayfish plague pathogen can be transmitted from the infected spiny-cheek crayfish also in other periods. For this purpose, experiments were set up to investigate A. astaci transmission from infected spiny-cheek crayfish to non-infected spiny-cheek or noble crayfish. As expected, the pathogen was transmitted to noble crayfish much more easily than to the uninfected American host. Nevertheless, we succeeded in the pathogen transmission also among spiny-cheek...
Synthesis and aplication of Dewar benzenes
Janková, Štěpánka ; Kotora, Martin (advisor) ; Roithová, Jana (referee) ; Svoboda, Jiří (referee)
Dewar benzenes are valence isomers of benzenes, which can be prepared by their thermic or photochemical rearrangement.1,2,3 They posses interesting physical and chemical properties due to the presence of the strained bicyclic framework. I studied synthesis of para-substituted phenyl Dewar benzenes and consequently kinetics of their thermal rearrangement for new information about mechanism of this unclear reaction. I also showed synthesis of new substituted aromatic and polyaromatic compounds, in which the key intermediates were Dewar benzenes (Scheme 1). Their chemical and physical properties are also going to be discussed.

Men and caves in the Neolithic Period
Peša, Vladimír ; Popelka, Miroslav (advisor) ; Svoboda, Jiří (referee) ; Pavlů, Ivan (referee)
Men and Caves in the Neolithic Period Vladimír Peša ABSTRACT From the beginning of archaeological excavations in the 19th century up to the present day, caves as archaeological sites have most often been interpreted as longer- or shorter-term settlements, hideaways or shelters for herdsmen; other interpretations that are considered for caves are cult functions and shelters for social outcasts. I see the beginnings of these notions of universal functions for caves in two contexts. Up until the second half of the 20th century there was a predominant interest throughout most of Europe in Palaeolithic history, and an interpretive model of Palaeolithic cave settlement was subsequently applied to frequently less distinct or even different find situations dating to post-Mesolithic periods. Secondly, at the close of the 19th century caves in the general consciousness of society (i.e. including archaeological) were mainly thought of as warfare shelters or as cover from inclement weather during agricultural activities away from the settlement. Speculation on the greater importance of cult activities and the symbolism of caves doesn't appear with greater regularity in literature until the 1980s; and yet, the settlement impression of caves persists. Using the Neolithic period as an example, the submitted work attempts...
Problems and perspectives of effective use of ICT at small schools from the viewpoint of their managers
Urbanová, Milena ; Svoboda, Jiří (advisor) ; Trojan, Václav (referee)
ICTs currently represent great potential for streamlining and improving of the educational process and its management in primary schools. But small schools have some specific features that complicate the use of ICT. The aim of this thesis was to implement the probe into the opinions and attitudes of directors of small schools on the current state and perspectives of ICT, as well as barriers they encounter in their schools. The work is of theoretical and also empirical character. As a method for the empirical part of the thesis the interview was used with a small group of directors (partial study) and a questionnaire with closed and free questions answered by 181 directors from the entire Czech Republic. In addition to answers to research questions also some suggestions for possible ways to overcome barriers and effective use of ICT in small schools were obtained from respondents.

Dynamic linking, debugging and tracing in HelenOS
Svoboda, Jiří ; Bulej, Lubomír (referee) ; Děcký, Martin (advisor)
HelenOS is an operating system that originated as a software project at the Faculty of Mathematics and Physics. So far it lacks support for dynamically linked libraries as well as support for process tracing and debugging. Dynamically linked libraries enable developing individual parts of large software systems independently and linking them later together without recompilation. The linking is carried out at load-time or run-time by the dynamic linker. The linker must nd all libraries used by the program, map them into memory and relocate them. Then it must resolve external (symbolic) references between the program and libraries. A debugger and a system-call tracer are essential development tools. They use a special system interface for their operation enabling them to suspend an application when certain events occur (such as a breakpoint or a trap). Then they may examine or change the application's memory contents and resume its execution. The main goal of this thesis is to implement support for dynamically linked libraries in HelenOS, namely the dynamic linker, and also a system API for debugging and tracing processes, including a demo application.
