Performance tests of the recycled aggregates to roads
Karásková, Romana ; Valentin,, Jan (referee) ; Stehlík, Dušan (advisor)
The work is divided into two parts. The practical part deals with the testing properties of soils which are using in new road in Nové Město na Moravě and the testing of recycled materials which could replace this soils from road. The aim this part is to obtain values of elastic modulus which are then inserted into the computational model. In the second part of work the track road is modeled in the software which uses the Finite Element Method to calculate and respect physical properties of different materials and a load. The result of work will be studies with comparison of displacement and stress generated to using existing soils and recycled materials.

Thermal treatment of waste with heat recovery
Strapko, Tibor ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
Following bachelor‘s thesis deals with one of the possible way of waste treatment nowadays, thermal treatment, focusing on the facilities using this secondary raw materials as a renewable source of energy, WTE plants (incinerations plants in history). At the beginning this work focuses on waste and its history, diversification, characteristics, origin and reasons of their continual grow in production. For complexity and possibility of comparison this work slightly deals with 2 other most popular ways of waste treatment, as well: recycling and waste disposal. Next part concers with thermal treatment of waste, specializing on WTE plants and its processes. These can be devided into 3 different parts: incineration part, energy utilization part and flue gas cleaning part. Big attention is concentrating on energy utilization system, which inconsiderable affects general effectivity of this facilities. Finnaly, there‘s a numerical evaluation of energy flows in process of waste incineration and its processing into simple block and computational model.

Life-time assessment of bridge based on nonlinear analysis and degradation modelling
Kucek, Martin ; Lehký, David (referee) ; Novák, Drahomír (advisor)
The aim of this work is to calculate the lifetime period of the bridge construction based on the nonlinear analysis and the degradation modelling. As a solution was the probabilistic nonlinear finite element analysis. The nonlinear numerical analysis is provided by the programme ATENA, developed by the Červenka Consulting. We have modeled one prefabricated bridge beam KA-73, which was overloaded by power effects until the structure was damaged. Observed limit states, limit state of the decompression, crack formation and limit state of the bearing were compared with characteristic material. It is possible to determine the maximum weighted capacity for the given construction based on discovered values.

Bridge over a local road and a brook
Zifčák, Karel ; Zich, Miloš (referee) ; Nečas, Radim (advisor)
The subject of this bachelor’s thesis is to study the bridge with a span of 24 meters, which bridges the local road and creek. The work focuses on the design window sill beam supporting structure with parabolic main beams connected to each other deck plate. The aim of the work is at the beginning study of three variants of possible bridges, the most suitable of them is selected and then static solution. Calculations of load effects are dealt with SCIA ENGINEERING 2013.1. a proposal is made according to standards EN.

Static solution of timber structure
Burza, Martin ; Zídek, Rostislav (referee) ; Brdečko, Luděk (advisor)
The Bachelor thesis is focused on an analysis of a wooden house truss. The first part deals with the load acting on spatially complex roof structure which is modeled in the Scia Engineer 2012 analysis software. Furthermore, the work considers the most stressed cross sections of wood elements and selected joints. In conclusion, the Bachelor´s thesis evaluates the original construction design.

Nonlinear analysis of reinforced concrete structures
Král, Petr ; Salajka, Vlastislav (referee) ; Hradil, Petr (advisor)
The aim is to design and evaluate nonlinear beams analysis, which will be subjected by four – point bending. Nonlinear analysis will be performed and evaluated on three beam models, the first of which will be made from plain concrete, the second of which will be made from reinforced concrete with reinforcement bars in the domain of tensile stress and the third of which will be made from reinforced concrete with reinforcement bars in domains of tensile and compressive stress. The thesis will be included formation of appropriate FE models, performance of nonlinear calculations with using nonlinear material model from a library of nonlinear material models multiPlas in the programming environment of software ANSYS and subsequent evaluation of results. Evaluation of results will consist from evaluation of nonlinear beams analysis and from evaluation of beams analysis according to ČSN EN 1992 – 1 – 1 without reinforcement bars and with reinforcement bars in these variants, next from comparison of nonlinear beams analysis with a beams analysis according to ČSN EN 1992 – 1 – 1 and finally from evaluation of the yield condition, which will be applied to the beams.

Modelling of traditional timber roof trusses
Vitásková, Petra ; Brdečko,, Luděk (referee) ; Zídek, Rostislav (advisor)
Bachelor’s thesis "Modelling of traditional timber roof trusses," analyzes the behavior of traditional timber roof trusses. Based on the actual design of roof trusses beam computational models are created, individual structural elements are assessed on the first and second limit state and some connections are considered. For the analysis of planar and three-dimensional model FEM programme SCIA Engineer 2011.1 is used.

A Blueprint of a Conscious Cognitive Agent with Two Internal World Models
Wiedermann, Jiří
We sketch a simple, yet cognitive powerful architecture of a cognitive agent. Our model differs from other similar models by using two complementary internal world models. We know that cognitive potential of one model goes beyond that of the earlier models by its support of algorithmic processes that in their consequences reflect higher cognitive functions such as imitation learning and communication, language, thinking and consciousness development.

Analysis of behaviour of selected high - speed track type
Vlach, R. ; Kotek, Vladimír
The paper shows possible modeling method of selected type of track. Selected type of track is a ski for skiing along grass. The paper describes creation of computational model of the ski. The computational model consists of a duct and many track links. The paper presents results of first computational simulations and their analyses. The computation simulation offers fundamental concept of behaviour of the ski.
