Optimization of Parameters Used in the Application of Elimination Voltammetry with Linear Scan
Navrátil, Tomáš ; Trnková, L. ; Hrdlička, Vojtěch ; Li, X.
Elimination Voltammetry with Linear Scan (EVLS) is a well-established mathematical method that aids in understanding an analyzed electrochemical system. In almost 30 years since its derivation, it has become a “black-box” technique that is applied automatically (in most cases due to its incorporation into a voltammetric software) without thinking about its fundamentals. However, the choice of optimum parameters under which DC voltammetric data (from which elimination curves are calculated) is crucial. This contribution deals with revealing the optimum ratio of applied scan rates and their absolute values (i.e., times of recording) in dependence on the character of the investigated system (diffusion-controlled process, adsorption-controlled process, etc.).

Optimization of Logistics System in Selected Company
RYCHNOVSKÁ, Magda
This work examines whether the logistic technologies and methods currently in use are suitable and sufficient for the future development of OPTOKON, a medium-sized company specializing in fiber optic technologies. The work presents the results of direct process observation, guided employee interviews, and data processing from the operational records of the information system. The most significant advantage lies in the implementation of the Just-in-Time logistic method, coupled with the use of barcodes and QR codes for marking, scanning, and tracking the movement of all materials and products within the company. This new marking system has a positive impact on the quality of products and services, and, most importantly, it enhances customer satisfaction by expediting and streamlining processes. The analysis and positive feedback from customers resulting from these changes will enable the company to make any necessary adjustments to its business activities, ensuring the company's sustainability and continued profitability.

Modern Optimization Methods for Interpolation of Missing Sections in Audio Signals
Mokrý, Ondřej ; Kowalski, Matthieu (referee) ; Koldovský, Zbyněk (referee) ; Rajmic, Pavel (advisor)
Poškození audio signálů je v praxi běžným, avšak nežádoucím faktem. Ke ztrátě informace může dojít nevhodným záznamem (nízký vzorkovací kmitočet či dynamický rozsah), chybou přenosu (výpadek vzorků), poškozením média či z důvodu rušení. Odstraňování takových poruch je možné pomocí inverzních úloh. Tato práce se konkrétně zaměřuje na situaci, kdy jsou úseky audio signálu o délce v řádu desítek milisekund zcela ztraceny a cílem je chybějící vzorky interpolovat na základě kontextu a vhodného modelu signálu. První část dizertační práce se věnuje metodám konvexní i nekonvexní optimalizace, které hledají řešení interpolační úlohy na základě předpokladu řídkosti časově-kmitočtového spektra. Obecný základ i některé algoritmy jsou převzaté z literatury a přizpůsobené interpolační úloze, řada modifikací a experimentálních přístupů je originální. Druhá část práce je zaměřena na využití nezáporné faktorizace matic, s níž lze sestavit pravděpodobnostní model spektrogramu signálu a tento využít pro jeho interpolaci. Z tohoto modelu pak vychází úspěšný rekonstrukční algoritmus, k němuž jsou v této práci odvozeny dvě alternativní metody. Závěr práce se věnuje rozsáhlému experimentálnímu ověření funkčnosti metod na skupině hudebních signálů. S využitím objektivních ukazatelů kvality interpolovaného signálu je ukázáno, že v jednotlivých třídách metod vedou navržené modifikace ke znatelnému zlepšení kvality či zlepšení konvergence oproti metodám základním. V rámci studovaného rozsahu poškození pak zejména algoritmy využívající faktorizace konkurují současným nejlepším metodám pro interpolaci chybějících úseků audio signálu.

This thesis focuses on the use of simulation to optimise processes in a paint shop. The aim of the thesis is to analyse the existing production processes and suggest improvements using simulation. In the analytical part of the thesis, the processes in the paint shop are described in detail and Petri nets are used to describe the logic of the processes in the paint shop. In the design part of the thesis, the problem and objectives are formulated, and the design of the simulation model is presented. The design describes the elements and methods used in the Plant Simulation software in which the model is created. Furthermore, different scenarios are simulated to optimize the painting process and the deposition areas. The simulation results are compared with the actual state of the paint shop. Finally, the results are discussed and recommendations are proposed to optimize the paint shop processes using simulation. This work presents new approaches to process optimization in industrial manufacturing.
