Ordering of Jobs for Pickling Lines
Plšek, Michal ; Tinka, Jan (referee) ; Kanich, Ondřej (advisor)
This work resolves the scheduling problem of multiple hoists transporting products between chemicals baths of pickling line. Harmonograms of products are calculated by modified Shifting bottleneck heuristic, which prevents product conflicts inside baths. Genetic algorithm NSGA-II is used for solution-space search. Web application built over the optimization process allows user to manage/edit products, hoists, baths, configuration parameters and optimization results. Applying proposed heuristic to smaller optimization tasks boosts production effectivity up to 30-45 % (comparing to naive harmonograms). The result of this work is application on the basis of which full-fledged C++ application might be programmed. Then it might be used for solving larger-scale problems.

Asynchronous Task Processing in PCS Project
Pospíšil, Michal ; Pavela, Jiří (referee) ; Rogalewicz, Adam (advisor)
Projekt PCS je distribuovaná aplikácia. Z toho vyplýva, že potrebuje spôsob ako spúšťať akcie vo vzdialených inštanciách PCS. Cieľom tejto práce je vyvinúť minimálne životaschopné riešenie pre spúšťanie akcií cez REST API, ktoré je implementované metódami asynchrónneho programovania. Tieto akcie však nie sú implementované asynchrónne, takže nemôžu byť spustené priamo z asynchrónneho kódu. REST API je preto napojené na asynchrónny plánovač, ktorý obchádza toto obmedzenie spúšťaním akcií v sade procesov (process pool). Plánovač skrýva akcie za abstrakčnú vrstvu úloh, ktoré uchovávajú informácie o stave a výsledkoch akcií. Všetky akcie potrebujú posielať aktualizácie svojho stavu klientom v reálnom čase. Toto je dosiahnuté jednosmerným komunikačným kanálom medzi akciami a plánovačom, ktorý správy od akcií ukladá do úloh. REST API umožňuje vytváranie, kontrolu stavu a rušenie spracovania úloh. Klient teda môže opakovane žiadať o stav úlohy a takto zobrazovať aktualizácie stavu z akcií. Klient tiež môže zrušiť spracovanie úloh, ktoré bežia príliš dlho.

Atmospheric Phenomena
Radouš, Jakub ; Milet, Tomáš (referee) ; Kobrtek, Jozef (advisor)
This bachelor's thesis deals with a visualisation issue of several atmospheric phenomena by means of the OpenGL library. The work contains theoretical bases for rain, snowfall, lightning, fog, wind, tornado and rainbow, which are further converted to the form of algorithms. The outcome is an application with graphical user interface that is able to display seven natural phenomena set in a landscape.

Web application tool for optical network monitoring
Rýdl, Pavel ; Horváth, Tomáš (referee) ; Holík, Martin (advisor)
The problematics of gigabit optical networks as well as web technologies suitable for a web tool implementation were studied within this thesis. An experimental web application for monitoring GPON frames is developed based on the proposed system architecture. The frontend is implemented using ReactJS and the Tornado web framework is used for backend implementation. Data for analysis are read from the stream using the Kafka platform.

From tornado to hydraulic turbine
Jízdný, Martin ; Rinka, Lukáš (referee) ; Rudolf, Pavel (advisor)
This bachelor thesis deals with vortex motion and contains two main parts. The first part refers to the principles of creation and evolution of vortex motion in nature and in technological applications. In both of these fields it is possible to find positive and negative impacts of vortex motion which influence the world significantly. The second part of this bachelor thesis refers to an experiment which main goal was to verify some selected qualitites of vortex motion and to determine hypothesis based on measurements. The final part of the experiment deals with the different methods of making vortex motion visible in laboratory conditions.

The asssessment of reconstruction of damaged building by tornado disaster.
Došková, Veronika ; Doležalová, Monika (referee) ; Čech, Josef (advisor)
The diploma thesis deals with the assessment of the reconstruction of a building damaged by a tornado. The first part is focused on basic terms from the field of real estate valuation and describes the issue at a theoretical level. It deals with the general procedure for dealing with property damage. It also considers a concrete solution to the situation of damage to a house by a tornado in the Czech republic in 2021. The practical part deals with the assessment of the feasibility of reconstruction or construction of a new house. The requirements for the reconstruction of a specific object are stated in the work. Subsequently, an itemized budget is drawn up, which calculates the costs of the reconstruction of the assessed building. For comparison, the second option is proposed, namely the demolition of the remains of the house and the construction of a new house. The goal of the work is to evaluate whether it is more profitable for the owner of the building to invest in the reconstruction of the damaged building, or rather to remove the damaged building and build a completely new building.
