Development of technologies for 3D printing of concrete structures
Roupec, Josef ; Hela,, Vlastimil (referee) ; Hela, Rudolf (advisor)
Subject of dissertation was to itemize testing methods in fresh and hardened state of cement paste or concrete. During this process some new testing methods and specimen creation protocols were proposed. Further was created list of used materials and mix design processes which led to list of used 3D printing mixture designs and 3D printers. Next part of dissertation was devoted to creation of 3D printing mix design and observations based on them. At~the end is proposed a radical change in testing methods which utilizes latest advancements in computer science and could be part of digital design process for construction.

Lumped Water Balance Rainfall-Runoff Model Within a Daily Computational Time Step
Bednář, Martin ; Marton, Daniel
This paper aims to show the developed software representing a lumped water balance rainfall-runoff hydrological model. The software allows the user to create a simulation model of the rainfall-runoff process in any catchment for which the user can provide the necessary measured climatological and hydrological data. The calibrated model then can be used to predict runoff from the catchment based on the predicted input data, allowing for some analysis of the impact of climate change on hydrological conditions in the landscape. The model is developed and tested on a part of the Thaya river catchment, the part above the Vranov reservoir.

Approximation of Evacuation Curve by the Polynomic Regression Method
Uhlík, Ondřej ; Dobiášová, Lucie ; Kratochvílová, Martina
Prediction of the evacuation process at the time of the emergency is crucial for the subsequent effective coordination of the evacuation and the intervention of the rescue units. Microscopic simulation tools are currently the most advanced method of evacuation modelling, however, their use in the operational phase of construction is inefficient due to the computational time of the simulations and dynamic input data. One of the outputs of the simulations is the evacuation curve. The paper proposes a simplification of the curve by the approximation method of polynomial regression, which demonstrates on basic evacuation scenario. The polynomial coefficients can be used to compile a training set of a machine learning model to predict real-time evacuation curves.

Collision Detection in Computer Graphics
Stupka, Filip ; Starka, Tomáš (referee) ; Pečiva, Jan (advisor)
This thesis is focused on the problem of collision detection between math defined primitive models and also on triangle networks that form complex polygonal models. Simulation of collision detection is very complex topic from performance standpoint and even though multiple methods that solve these problems do exist, in most cases they are too slow to be any useful and therefore it is encouraged to find optimizations and alternate solutions. In order to be able to work with collision simulation we need to understand discrete and continuous movement techniques and we need to be able to predict behavior of certain objects. This thesis therefore is based on game engine development, optimizations and implementation of collision detection algorithms.

Simulation in Unity
Kropáček, Vojtěch ; Vlnas, Michal (referee) ; Milet, Tomáš (advisor)
V této práci je stavěno na nedávném vzestupu popularity entity komponent systémů v oblasti vývoje her. Cílem práce je vytvořit aplikaci simulující ekosystém v programu Unity engine. V práci se nachází popis výhod entity komponent system architektury, atributy a rozdíly oproti tradiční architektuře. Pro běh simulace byl využit framework s názvem Entitas uvnitř Unity enginu. Dokončená implementace emuluje Lotka-Volterra rovnice, také známy pod názvem rovnice lovec-kořist. Nálezy simulace jsou prezentovány v grafech, které splnují očekávání. Práce také poskytne hlubší porozumění entity komponent system architektury a její specifikace v rámci implementace Entitas frameworku. Shrnuje jeden z přístupů k tvoření jednoduchého ekosystému a výsledné nálezy z proběhlých simulací.

Integrity measures under clinical conditions and in selection situations. The use of integrity test in clinical practice and at work psychology
Příhodová, Tereza ; Preiss, Marek (advisor) ; Miovský, Michal (referee) ; Bob, Petr (referee)
Univerzita Karlova 1. lékařská fakulta Studijní program: Psychologie Studijní obor: Lékařská psychologie a psychopatologie Tereza Příhodová, M.A. Měření integrity v klinických podmínkách a v situaci výběru Využití testu integrity v klinické praxi a psychologii práce Integrity measures under clinical conditions and in selection situations The use of integrity test in clinical practice and at work psychology Disertační práce - abstrakt v anglickém jazyce Vedoucí závěrečné práce/Školitel: doc. PhDr. Marek Preiss, Ph.D. Konzultant: PhDr. et PaedDr. Pavel Harsa, Ph.D. et Ph.D. Praha, 2021 ABSTRACT Integrity is a psychological and philosophical construct, which is closely related to the concepts of moral psychology. In different psychological disciplines it is often associated with related constructs including conscientiousness, virtue, honesty or emotional stability. In Czech psychological and psychiatric practice integrity is a variable, which is commonly not measured and evaluated as a personal asset, mainly due to the fact that there is a lack of proper instruments, which would be accessible to clinicians or researchers. The main goal of this dissertation thesis was to introduce newly developed integrity test, which is applicable in clinical and in non-clinical settings. Thus, this thesis summarizes the...

Warehouse Simulation and Product Distribution Optimization for Increased Throughput
Kočica, Filip ; Kolář, Martin (referee) ; Kodym, Oldřich (advisor)
This thesis focuses on the storage location assignment problem using modern meta-heuristic techniques combined with realistic simulation. A graphical tool implemented as part of this work is capable of warehouse model creation, generation of synthetic customer orders, optimization of product allocation using state of the art techniques, extensive warehouse simulation, and a pathfinder capable of finding the shortest path for orders going through the system. The work presents the comparison between different approaches based on many parameters to reach the most efficient allocation of products to warehouse slots. The author conducted tests on an experimental warehouse featuring almost twice the throughput -- 57%. The benefit of this work is a possibility to create model of an already built warehouse and its simulation and optimization, driving impact on the throughput of the warehouse, saving the user's resources, or helping him in planning and bottle-neck identification. Furthermore, this thesis introduces a new approach to warehouse optimization and new optimization criteria.

Optimization of the injection process of a diesel engine dosing module component
Ohnút, Lukáš ; Podaný, Kamil (referee) ; Žák, Ladislav (advisor)
This diploma thesis deals with optimalization of the injection process of the part and its implementation into serial production. In the first step, the injection mold was tested and injection parameters were initially defined. In the next step, simulations were created in the CADMOULD program. These simulations calculated theoretical injection parameters and these were compared with the parameters set on the injection molding machines. Then, the shape measurement protocols were prepared, according to which the shapes in the cavities of the injection mold were optimized. Finally stress tests were performed, which detected problems in the injection process.
