Transportation theory in practice
Sojka, Jiří ; Dlouhá, Zuzana (advisor) ; Sokol, Ondřej (referee)
One of the most widely used optimization problems is vehicle routing problem. With minor adjustments of the limiting constraints it is usable on large variety of problems in fields of logistics or delivery of goods. The goal is to help company Víno Hruška s.r.o. to find a route for distribution of advertising materials to their own branches in the Czech Republic and Slovakia. First part is dedicated to theoretical introduction to methods of linear programming, second part is practical and uses described methods with real data. Routes found with heuristic methods and with optimization software are compared.
Comparison of Selected Real Traffic Accidents to Crash Tests
Rybková, Tereza ; Sojka, Jiří (referee) ; Semela, Marek (advisor)
This master’s thesis presents an overview of the basic forces acting on the vehicle, the basic methods of analysis of accident, collection of data used in the analysis of accidents, an overview of the basic performance criteria and thresholds used in the homologation test of occupant protection in a frontal impact, used crash tests, homologation tests and specifications for these tests. Attention is paid to Euro NCAP crash tests and to homologation tests of vehicles Skoda Octavia with aim to try to compare them with selected accidents in terms of depth and character deformation and evaluate findings comparision.
Study of Speedometer's Hand Behaviour by Traffic Accident
Polnický, Václav ; Sojka, Jiří (referee) ; Semela, Marek (advisor)
This diploma thesis deals with the ability to determine impact speed of vehicles in traffic accidents. Thesis tries to find out whether jammed needle of speedometer and tachometer, as well as needle's imprint, could provide relevant informations for traffic accident analysis. The outcome is formulation, whether these informations are trustworthy, or under which circumstances are valid.
Condensation heat exchanger beyond CHP unit
Sojka, Jiří ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this thesis is to design the condensation heat exchanger for stationary engine running on natural gas. Flue gas condenser is designed for universal use of refrigerants (i.e. water or 35% fusion ethylene-glycol in water) and their working temperatures. The work includes theoretical, computational and design part. In the attachment is located the drawing documentation to flue gas condenser.
Renewable energy souurce in Czech Republic
Sojka, Jiří ; Fortelný, Zdeněk (referee) ; Moskalík, Jiří (advisor)
This thesis is focusing on exploration of various renewable energy sources used in mass-energy in the Czech Republic. The first half of this thesis is focused to brief description of each renewable energy source. In the last part of this work was selected energy from biogas as the source of renewable energy to be more detailed described.
Influence of Depreciation of Czech Crown Towards Euro on Czech Unemployment Rate
Sojka, Jiří ; Čermáková, Klára (advisor) ; Mirvald, Michal (referee)
This work deals with an unemployment rate diference in the Czech Republic if Czech crown goes down towards Euro from the origin of an European currency until 2009. The first part of this work discusses Euro and its presumtions to influence Czech labour market. A connection between Euro and chosen macroeconomic indicators, which influence Czech unemployment, is shown there and the influence of Czech crown depreciation towards Euro with its impact to unemployment rate is explored too. There is a regression model used in the second part. It describes relationships of the exchange rate and the rate of unemployment. The objective of this work puts in light a fact that depreciation of Czech crown influences the Czech unemployment rate. If Czech crown goes down towards Euro about 1 CZK, the unemployment rate increases in 7,9 %. Czech currency and its cohesion with Euro is clear, which is improved in a practical example in the end of the work.
