Electronic thermostat
Flek, Tomáš ; Číž, Radim (referee) ; Lattenberg, Ivo (advisor)
In essence, this thesis focuses on a search for an optimal measuring method suitable for converting a temperature measurement into an electrical signal that can be processed easily in the other parts of the electrical circuit. The selection of the measurement method was guided by the need to find one suitable for the temperature range in question. For each method there are different temperatures sensors, each with different parameters. This thesis covers in detail the various kinds of temperature sensors and notes their advantage and disadvantage, accuracy, repeatability, non-linearity, longevity, and purchasing price. The thesis also investigates how to cope with non-linearity of the selected temperature sensor while also listing various methods for non-linearity compensation and their effect on the overall measuring. A part of the thesis presents a design of a suitable thermostat that was selected on the basis of this work to provide suitable measuring properties and be most cost effective.

Inherent instability of financial markets
Hladík, Jan ; Buben, Radek (advisor) ; Znoj, Milan (referee)
The main aim of this presented diploma thesis is to help build a systematic understanding of the political and social foundations of global financial markets, their operations and impacts on the global power affairs. The thesis highlights the dynamic complexity of the post financial crisis state of the World with its itra- and inter-social features. It instrumentaly uses critique of a free market agenda and neo-classical economy which contrasts the Efficient Markets Hypothesis with Hyman Minsky's Financial Instability Hypothesis (FIH), taking into account the dynamic complexity of financial markets. This approach offers analytical tools that can account for crisis through processes endogenous to contemporary financial capitalism. I shall argue that a financially complex system is, according to the FIH, inherently flawed and unstable. After a theoretical and historical review, the thesis discusses various aspects of the process of austerity regime and its social consequences. This provides an opportunity for analyses of the ongoing existence of interstate competition, of militarised foreign policy, and of other international, at times violent conflicts. In an effort to make sense of some of these phenomena, I instrumentaly use the study of geoeconomics that builds on some fundamental assumptions...

Bending of Beam with Free Ends on Non-linear Subsoil
Sysala, Stanislav
A semi-coercive problem with a beam on a unilateral elastic subsoil of Winkler type is investigated in the contribution. Firstly, the existence, the uniqueness and the continuous dependence on data of the problem solution are discussed. Secondly, the problem is approximated by the finite element method, where the subsoil is replaced by insulated "springs" due to a numerical quadrature. The relations between the original problem and the family of approximated problems are introduced. Thirdly, suitable numerical methods of Newton type are introduced. The convergence analysis of the methods is investigated. The dependence of the methods on the discretization parameter and the load is also discussed. And finally, some of the theoretical results are illustrated on numerical examples.
