An Apartment House - heating
Vyhnánek, Jan ; Čupr,, Karel (referee) ; Treuová, Lea (advisor)
Bachelor work consists of theoretical and numerical part. In the theoretical part deals with various methods of heating in apartment buildings. The numerical part deals with individual part of the heating system in the apartment building. For heating the apartment building was chosen central heating system with indirect hot water. As the heat source was chosen gas heat pumps in combination with condensing boilers.

Egocentric module for episodic memory
Vyhnánek, Jan ; Brom, Cyril (advisor) ; Sýkora, Ondřej (referee)
The present research in cognitive psychology concerns with the issue of how human beings remember positions of objects in space - and what mental representation of space they create. Scientists infer from experiments that human beings create several spatial representations which differ in accuracy and rate of forgetting and which are specified with respect to different spatial frames of reference. However, we do not know how exactly these representions work. As far as we know there is no computational model concerning with this issue, which would be useful for understanding of these representations. The goal of this work is to extend the model of episodic-like memory developed at MFF UK with a mechanism of creating spatial representations. We will examine how the representations are created and which representations are the most important for orientation of a human-like agent. The model was tested on simulations of a psychological experiment and it partially predicted its results. The goal of the model is not to give a full answer to this problem. It is supposed to be an attempt for starting research in the area which has not been researched this way yet. The results of this work may contribute to better understanding of how human beings represent positions of objects and it may be useful for designing...

Signal complexity evaluation in the processing of functional magnetic resonance imaging
Vyhnánek, Jan ; Boldyš, Jiří (advisor) ; Dvořák, Jiří (referee)
Functional magnetic resonance imaging has been recently the most common tool for examining the neural activity in human and animals. The goal of a typical data-mining challenge is the localisation of brain areas activated during a cognitive task which is usually performed using a linear model or correlation methods. For this purpose several authors have proposed the use of methods evaluating signal complexity which could possibly overcome some of the shortcomings of the standards methods due to their independence on a priori knowledge of data characteristics. This work explains possibilities of using such methods including aspects of their configuration and it proposes an evaluation of performance of the methods applied on simulated data following expected biological characteristics. The results of the evaluation of performance showed little advantage of these methods over the standard ones in cases when the standard methods were possible to apply. However, some of the methods evaluating signal complexity were found useful for determining the regularity of signals which is a feature that cannot be assessed by the standard methods. Optimal parameters of the methods evaluating signal regularity were determined on simulated data and finally the methods were applied on the data examining emotional processing of...
