Estimating data with use of interval analysis
Pelikánová, Petra ; Horáček, Jaroslav (advisor) ; Černý, Michael (referee)
This work is focused on estimating interval data by real functions and interval functions. It presents possibilistic and necessity models of interval regression and compares its strong and week formulations. Further we describe algorithms of linear and nonlinear estimation. The application part is based on demonstration of tolerance method and subtracting tolerance method analysing real cases. 1

Psychologically-plausible and connectionism-friendly implementation of long-term memory
Milota, Martin ; Horáček, Jaroslav (advisor) ; Bálek, Martin (referee)
In recent decades, the influence and sophistication of connectionist systems has soared. The fields of their applications are countless - image re- cognition, data mining, robotics, and many more. A part of the thesis focuses on commonly adopted distributed data representations suitable for connectionist systems, devising an extension and testing its usefulness. The goal of the thesis is to use these extensions to design and implement a model of the long-term memory based on a prevalent psychological theory.

Visualisation of interval data
Mečiar, Martin ; Horáček, Jaroslav (advisor) ; Rada, Miroslav (referee)
The thesis is focused on visualisation, comparison and modification of outputs of interval solvers for solving a continuous constraint satisfaction problem. The author's designed solution for the approximation of outputs of solvers is presented in the thesis. The approximation of outputs of solvers is transformed into the problem of visual reallocation of the sets of outputs of solvers on a finer level than interval box level. Main part of the thesis is the program on added CD that allows visualisation, comparison and modification of outputs of interval solvers. The program is written in C++, but can be compiled as a MEX file for MATLAB. A user documentation and a technical documentation for the program are included in the thesis. The thesis shows several examples of program output in the devoted chapter. Powered by TCPDF (www.tcpdf.org)

A Chapter of the Historiography of Art History and Heritage Preservation. František X. Beneš (1820 - 1888).
Horáček, Jaroslav ; Konečný, Lubomír (advisor) ; Biegel, Richard (referee)
The origins of heritage conservation in Czech lands are usually dated back to the year 1850 when the Central Commission for Research and Conservation of Architectural Heritage (Central-Commission für Erforschung und Erhaltung der Baudenkmalen) was founded in Vienna. In the years 1854-1855, fourteen conservators were assigned to the Bohemian area whose job was to search for and describe heritage sites and they also were to initiate their repairs. One of those fourteen conservators was one - still rather unbeknown - František X. Josef Beneš (1816-1888), conservator of Čáslav county, with whose life and work this paper is concerned. He was born into a family of an establishment bureaucrat Josef Alois Beneš in Český Dub, however, soon the family moved to Osek u Rokycan. Having graduated from grammar-school he continued studying at Prague Polytechnic school where he focused on chemistry and sugar industry. He started as a sugar industry adjunct in Dobrovice and later he was moved to Suchdol u Kutné Hory to act as a manager of a local sugar factory. Having helped František Alexander Heber with his work Böhmens Burgen, Vesten und Bergschlösser to whom he gave valuable data about many a building in Kutná Hora area, Beneš himself began to be interested in conservation. In the 1840'swe can already find Beneš...

A tool for evaluation of different methods for solving nonlinear equations
Do Manh, Tuan ; Mikula, Tomáš (advisor) ; Horáček, Jaroslav (referee)
The objective of this work is to create a tool for solving nonlinear equations using numeric methods. It uses both slow working methods, such as bisection method or regula falsi method, and fast working methods, such as Newton's method. The Newton's method, while fast, can be very problematic in certain scenarios. It does not always converse to the root of the equation. That is why in this work, I try to implement modified methods, which attempt to deal with the imperfections of the Newton's method. The program is suppose to be a good tool for comparing and evaluating the efficiency of each methods in different situations.

Overdetermined systems of interval linear equations
Horáček, Jaroslav ; Hladík, Milan (advisor) ; Ratschan, Stefan (referee)
This work is focused on overdetermined systems of interval linear equati- ons. First part consists of introduction to interval arithmetics and interval linear algebra and basic theory of interval linear systems. In the second part various methods for solving overdetermined interval linear systems are de- scribed. By solution of overdetermined interval system we mean union of all solutions of all subsystems. Known and our variants of algorithms are discussed. We introduce our subsquare method. All mentioned methods are implemented in one toolbox for Matlab. Methods are tested on solvable and unsolvable overdetermined systems. For solvable systems we test solution enclosure, time and special features of methods. For unsolvable systems we test detection of unsolvability. At the end of this work we provide basic in- troduction to Intlab. 1

Italian Renaissance Chests in the Czech Collections
Horáček, Jaroslav ; Mergl, Jan (advisor) ; Karasová, Daniela (referee)
This work deals with the subject of Italian renaissance chests (cassone) in Czech collections, mapping the fund of cassones in the Czech Republic and its critical evaluation. The most important collections of the Moravian Gallery in Brno, North Bohemian Museum in Liberec, Museum of Decorative Arts in Prague, the National Museum in Prague, the National Gallery in Prague and Silesian Museum in Opava were selectively processed for this research. The attention is also paid to decorative techniques, materials, design, typology and construction solutions used in the cassone- making process. The issues of differences in the production of cassones among various Italian regions are also outlined. This work also contains a concept of an Italian-renaissance chests catalogue in the Czech collections.

Cell shape simulation using cytoskeleton model
Horáček, Jaroslav ; Bílý, Tomáš (referee) ; Bálek, Martin (advisor)
This work is focused on computer modelling of cells' behavior. Emphasis is layed on simulating of cell shaping. The goal is to design theoretical structure, which suitably represents cytoskeleton of cell. Our model is based on Zygotic graph. It defines cell reactions to incoming stimulation from environment. Unlike previous models we newly add Fill graph and Granary graph to the Zygotic graph. In order to modelling of cell shaping we define membrane flexibility. We also define mechanism of Cytoplasmatic pulse. It is necessary for amoeboid movement modelling. We added new structure called Granary, which represents storage ability of cell. We use our model to simulate movement of amoeba cell. Another example shows white blood cell moving through blood vessel wall. We also attempt to simulate growth of cells inside closed environment.
