Network Capacity Optimization on UNIX
Pelikán, Martin ; Galamboš, Leo (advisor) ; Steinhauser, Antonín (referee)
Title: Optimizing the utilization of networks' capacity on unix-like systems Author: Martin Pelikán Department: Department of Distributed and Dependable Systems Supervisor: RNDr. Leo Galamboš, Ph. D., Department of Distributed and De- pendable Systems Abstract: Modern unix-like systems contain very powerful network stacks with configuration options often beyond operators' understanding. A comparison of available algorithms, documentation and visualization of certain components help their understanding, leading to better configuration choices. By explaining the network stack from the drivers up to the network layer will exhibit problems with timekeeping, burst traffic processing or queue management with regard to classification, scheduling or traffic regulation options in Linux or OpenBSD. The thesis works as an overview of implemented algorithms and updated documen- tation of Linux's actions and filters, while the implementation introduces a new portable tool to visualize existing configuration on remote machines without the need of modifying them. Keywords: network internals, traffic shaping, traffic classification, queue ma- nagement 1

Příbram and its everyday life during the ocupation 1939 - 1945
ŠORFOVÁ, Petra
The task of this diploma thesis is to describe events in years 1939-1945 which took place in Protectorate of Bohemia and Moravia and which had also specific impacts on the central-Bohemian town of Příbram. The thesis is based on written sources of information held in State Regional Archive in Příbram, accessible literature and at last but not least memories of personal observers who lived through the war when they were children. In this work I concentrate on the impacts of the war on lives of ordinary people who suffered their personal tragedies and experienced encounters that completely changed their lives. The thesis is divided into 7 chapters. First chapter deals with the history of Příbram beginning with prehistory and finishing with contemporary days. This chapter also mentions Svatá Hora and Březové Hory because these places create an important part of the location. Second chapter describes the situation right before the war and feelings of people towards the declaration of the protectorate. The next chapter talks about the history of Mining Technical University which was a part of the town nearly for 100 years. The university, as well as many other schools of this type, was closed and some of its students were arrested and deported to the concentration camp Sachsenhausen. Fourth charter is about Jewish and Gipsy question which is a quite popular topic even today. Fifth chapter includes description of the atmosphere of everyday life during the war through children´s eyes but also cultural life of the town. Sixth chapter focuses on the period of the great terror after the assassination of Reinhard Heydrich, which influenced also people in Příbram. The last chapter speaks about the fight of Czech people to re-establish the independent state in which people from Příbram and its surroundings participated as well. This chapter also deals with the last fight in the central Europe which took place near the town of Příbram. The thesis combines general context and particular events happening in Příbram and it tries to look closely at the period of the Second World War full of anxiety, worries and hope.
