Master's thesis deals with present state assessment of flood hazard on rivers Svitava and Svratka in the southern part of Brno. Flood discharges Q5, Q20, Q100 and Q100N were solved using coupled 1D/2D numerical model. All results were evaluated as maps of hazard.

This paper deals with interaction of different physical phenomena in asynchronous motor. The first part of this work is devoted to computing of electrical ratios in asynchronous motor. By using the equivalent circuit in the shape of Gamma-circuit the equation for computing of currents, performances and losses of asynchronous motor are derived. The second part describes calculating of electromagnetic circuit and iron-core losses. In the next part there is the first part of associated model created which respects electric and electromagnetic ratios in the asynchronous motor. This model can be used for example to pursuance of variation of flux density caused by resizing load. In this model the unconventional way of computing the magnetizating inductance and resistance coresponding to iron-core losses is used. The next part deals with calculation of machine warming using the thermal network. In the last part there is a complete coupled model assembed which respects the interaction of electrical, electromagnetical and thermal ratios of induction machine.

This thesis describes complex modeling of asynchronous motor by finite element method. Complex modeling concerns to making models based on different physical principles and their connection. Models are made in Ansys program components and their connection is made in program Ansys Workbench. This thesis includes creating electromagnetic model, thermal model, mechanical model and coupled model which connect partial models.

We discuss the so-called two-temperature model in linear thermoelasticity and provide a Hilbert space framework for proving well-posedness of the equations under consideration. With the abstract perspective of evolutionary equations, the two-temperature model turns out to be a coupled system of the elastic equations and an abstract ordinary differential equation (ODE). Following this line of reasoning, we propose another model which is entirely an abstract ODE.We also highlight an alternative method for a two-temperature model, which might be of independent interest.
