Truck aerodynamic parameters
Šilar, Josef ; Vančura, Jan (referee) ; Hejtmánek, Petr (advisor)
The main goal of this bachelor´s work is to depict and describe terms form the aerodynamics field in order to understand the problem of aerodynamics of the vehicles. Here is created overall view of constructive elements that lower aerodynamic resistance of vehicles and methods of survey of aerodynamic parameters. The work also contain the difference of mentioned parameters of suburban and truck cars.

Modelica in physiological modelling. Models with spatially distributed parameters, Authorin educational simulators.
Šilar, Jan ; Kofránek, Jiří (advisor) ; Maršálek, Petr (referee) ; Roubík, Karel (referee)
Mathematical models in physiology are useful to formulate and verify hypotheses, to make predictions, to estimate hidden parameters and in education. This thesis deals with modelling in physiology using the Modelica language. New methods for model implementation and simulator production were developed. Modelica is an open standard equation-based object-oriented language for modelling complex systems. It is highly convenient in physiology modelling due to its ability to describe extensive models in a lucid hierarchical way. The models are described by algebraic, ordinary differential and discrete equations. Partial differential equations are not supported by the Modelica standard yet. The thesis focuses on two main topics: 1) modelling of systems described by partial differential equations in Modelica 2) production of web-based e-learning simulators driven by models implemented in Modelica. A Modelica language extension called PDEModelica1 for 1-dimensional partial differential equations was designed (based on a previous extension). The OpenModelica modelling tool was extended to support PDEModelica1 using the method of lines. A model of countercurrent heat exchange between the artery and vein in a leg of a bird standing in water was implemented using PDEModelica1 to prove its usability. The...

The problems of driver's participation during loading and unloading and his responsibility - the examples of HOPI
Melicharová, Michaela ; Novák, Radek (advisor) ; Šilar, Jan (referee)
The aim of the diploma thesis is the analysis of driver responsibility during the loading and unloading of the goods at HOPI, the characteristics of the complaints grounds for the selected partner and the presentation of one type of complaints with a proposal to solve how to prevent further damage to the goods. The first part analyzes the responsibility of the carrier, where distinguishes several types of liability including the extent of liability for loss, damage or destruction of the consignment. The practical part describes the work and responsibility of the driver at HOPI. The reasons for Savencia's complaints are characterized, and the last part of the thesis concerns with one reason of complaint (damage of goods) and then proposes a solution.
