Wood chip belt conveyor
Kamínek, Jan ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The bachelor's thesis in the introduction contains research on the topic of the belt conveyor and an analysis of the anchoring of the conveyor. In the following chapters there is a design and functional calculation of a belt conveyor for transporting wood chips with an assumed specific weight 650 kgm-3. The belt conveyor was designed with a transport distance of 19 m, a height difference of 3 m and a transport performance of 19,000 kg·h-1. A more detailed analysis of the properties of the transported material is also carried out. Finally, the strength of the driven and drive shaft is verified by calculation.

The Quiet Omnipresence
Bodlák, Ondřej ; Dvořák, Vojtěch (referee) ; Mikyta, Svätopluk (advisor)
The work, entitled The Quiet Omnipresence, themes the metaphor of grid and line as representing the source elements necessary for the growth of whole forms. It relies on a study of landscape and urban scenery, its quiet ubiquitous mechanisms and processes. The jumble of lines creates a sensorially elusive monochromatic surface that the observer can encounter when looking at organic structures for longer periods, as well as industrially tuned urban compositions. It explores the relationship of order and chaos in its opposite but paradoxically mutually inexorable connotations. The work mostly relies on a specific and not uncommon type of space often right in the middle of cities – vague terrains, places forgotten and deliberately overlooked, in which banal biological processes slowly take the helm determining the direction of a seemingly random development.

Urban, Miroslav ; Frühbauer, Jiří (referee) ; Malášek, Jiří (advisor)
This bachelor's thesis focuses on the constructions of waste disposers. It contains a description of creating a new structural design. It was created from a research. The research is about the types of machine constructions in this area. Bachelor's thesis is also about placement of these machines in the crushing lines. Bachelor's thesis also contains an overview of manufacturers and companies that deal with the constructions in the question. The design was constructed based on the DUC16 from the company Unikasset. regarding the waste crusher DUC16 from Unikasset. After carrying out the balance sheet and functional calculations, the waste crusher was constructed. The output of the work is an assembly drawing.

Analysis and design of the use of the existing building in the village of Stařeč
Janovská, Dagmar ; Hlavinková, Vítězslava (referee) ; Čech, Josef (advisor)
This diploma thesis introduces an analysis and a suggestion for a new usage of a structure, which is located in Stařeč, through the method of highest and best usage, otherwise known as HABU. The first part focuses on explaining terms used in the thesis. Afterwards, methods and their reasonings are explained. The next part introduces suggestions for a new usage of the structure, which are examined by HABU methods, inappropriate suggestions are eliminated. The chosen suggestion reaches the best and highest usage for Stařeč.

Development of water show control
Havran, Lukáš ; Pruša, Radomír (referee) ; Štěpánek, Vojtěch (advisor)
This thesis deals with the design methodology for controlling a digital water curtain. The research section focuses on analyzing control systems suitable for this technology and on software tools that enable the implementation of a user application designed to control the water curtain. Based on the research, the practical part involves the implementation of a user application for composing and executing water scenes. Another aspect of the practical part is the selection and programming of control hardware that manages the water jets. The control principle relies on communication between the user application and the control hardware. The practical part is further complemented by the construction design of the digital water curtain in the form of a 3D model, which includes all construction elements, including the control hardware.

Návrh konstrukce přípravku pro svařovacího robota
HAMR, Jan
Robotic welding is currently widely used in the field of Engineering Technology. At the robotic workplaces, welding fixtures are designed for the possibility of clamping, increase of the efficiency and the accuracy of production. The Engel company con-cerns with the conversion from manual welding of weldments to robotic welding. The literature review of this paper describes the robotic welding technology used at Engel. The review focuses on describing the design of the welding fixtures currently in use. Moreover, it focuses on the description of alternative clamping methods. Based on the literature review, three innovative variants of welding fixture design of the specified weldment were proposed for the robotic workstation of the Valk Welding company. Accurate 3D CAD models of the different variants of the welding fixture design with different types of clamping elements were created and and variants were compared.

Difuzní vlastnosti OSB desek v důsledku zasažení nadměrnou vlhkostí.
Žižková, Lucie ; Vertal', Marián (referee) ; Chybík, Josef (referee) ; Bečkovský, David (advisor)
The presented dissertation focuses on the change of diffusion properties in oriented strand board (OSB) panels after exposure to excessive moisture. OSB panels undergo a change in their diffusion properties after being affected by excessive moisture and subsequently dried, causing them to deviate from the original design of the wooden wall structure. The aim of this study is to describe the experimentally measured change in diffusion properties and incorporate it into the composition of a real wooden wall structure, evaluating its performance through computer simulation. The introduction of the dissertation provides the theoretical basis for the experimental section, which includes measurements of water absorption, diffusion properties, and the risk of mold growth. The experimental section describes the approaches and methods used to achieve the objectives of the dissertation. The measurements were conducted on test samples of OSB panels in the laboratories of the Institute of Civil Engineering. After being exposed to excessive moisture, the test samples were dried using two drying methods. The dried test samples were placed in testing assemblies, where diffusion was measured using the dry cup method. The measurements were carried out in two stages, with more than 80 samples measured in each research stage. In the final part, the measurements are evaluated through graphs. The change in diffusion properties was then incorporated into the composition of a real wooden wall structure and assessed using computer simulation, which is more commonly used in practice according to ČSN 73 0540 (Czech Technical Standard).
