Time resolution of TileCal and searches for heavy metastable particles
Pagáčová, Martina ; Leitner, Rupert (advisor) ; Němeček, Stanislav (referee)
Title: Time resolution of TileCal and searches for heavy metastable parti- cles Author: Martina Pagáčová Department: Institute of Particle and Nuclear Physics Supervisor: Doc. RNDr. Rupert Leitner, DrSc. Supervisor's e-mail address: Rupert.Leitner@cern.ch Abstract: In the present work, the timing of the ATLAS TileCal is stud- ied using the single hadron collision data. The time resolution and also the mean time response depend on the energy deposited in a given cell. The results are compared to the previous analysis with jets and muons. Precise time-of-flight measurement using TileCal can be used to identify the heavy long-lived particles predicted by the models of physics beyond the standard model. Their mass can be reconstructed by combining with the momentum measurement in the ATLAS inner detector. Finally, the mass resolution of an exotic particle with mass M = 600 GeV is estimated. Keywords: ATLAS experiment, TileCal, time resolution, stable massive particles

Proton-Proton Interactions at the ATLAS Experiment at the LHC Accelerator
Přibyl, Lukáš ; Němeček, Stanislav (advisor) ; Soustružník, Karel (referee) ; Kupčo, Alexander (referee)
In this thesis the potential of the ATLAS detector to exclude or discover quark compositeness is studied in detail. There were four dierent sensitive analysis methods developed for this purpose. These methods use a detailed information about inclusive dijet pT-spectrum or dijet angular distribution and two of them use Bayesian technique (as is usual in similar analyses at Tevatron). For all four methods a larger number of systematic errors was taken into account and their inuence was studied in detail too. It is also shown, that the early data exclusion limit on quark compositeness reachable by the ATLAS experiment is + LL = 10.3 TeV at 95% C.L with 100 pb 1 of collision data of a sucient quality. This limit is considerably higher than the current limit known from Tevatron: + LL = 2.7 TeV at 95% C.L. The highest exclusion limit on quark compositeness with expected total amount of data to be collected by the ATLAS experiment is above 22 TeV, assuming 3% jet energy scale uncertainty.

Confessional political system and informal networks as the reasons of economic decline in Lebanon
Němeček, Stanislav ; Chalupníček, Pavel (advisor) ; Šmíd, Jan (referee)
This thesis attends the problem of institutional and political structure in a post-war economy of Lebanon. Lebanon was one of the countries in the Near east, which tried to apply principles known as Washington consensus. On this case we try to demonstrate the problem which appeared also in other countries of the world, where the same set of principles was applied and it was the insufficient attention dedicated to the issue of informal networks. We pay special attention to a confessional system in Lebanon which is based on division of powers on the basis of religion. This type of political structure produces creation of informal networks which substitute state apparatus and instigate corruption. The thesis proposes a modification of Lebanese system which will treat the institutional background with greater attention.

Corporatization and outsourcing - ways to more effective public sector?
Němeček, Stanislav ; Gráf, Václav (advisor) ; Doležalová, Antonie (referee)
The aim of this bachelor thesis is to introduce specific problems which occur in the management of public sector organizations. We are going to compare distinct motivational factors that are typical both for managers and employees in civil offices and private companies. We will closely look at the method of corporatization, which brings managerial elements from private to public sector. Our next objective is to analyse outsourcing and his limits. Practical part of the work will focus on the results which were achieved by corporatization in Canadian public sector. Further we will evaluate the consequences of outsourcing on the example of urban mass transportation in Jablonec nad Nisou, Czech Republic. We will try to show the possibilities of cooperation between the city and private firm as business partners.
