Models for Predicting Business Financial Performance
Vakhrushev, Dmitrii ; Oulehla, Jiří (referee) ; Luňáček, Jiří (advisor)
The thesis focuses on models for predicting the financial performance of the ALZA company, where it focused on emphasizing the strong financial performance and stability of the company. Key factors contributing to ALZA's success will be mentioned, such as consistent revenues, profits, effective cost management and investment in innovation. In addition, the work would also focus on potential strategies for further growth, such as exploring new markets, strengthening online sales, diversifying product offerings, and strengthening relationships with customers and suppliers. Emphasizing the importance of continuous innovation, market monitoring and strategic investment will demonstrate ALZA's readiness for future success and market expansion.Using financial data for the period 2017 to 2022, market trends and industry benchmarks, accurate predictions can be made regarding ALZA's future financial results. Implementing advanced modelling techniques and incorporating different scenarios can provide valuable insights for strategic decision-making.

Analysis of Malware Behavior using Large Language Models
Rádsetoulal, Vlastimil ; Homoliak, Ivan (referee) ; Očenášek, Pavel (advisor)
Táto práca skúma využitie veľkých jazykových modelov (LLMs) vylepšených technikou Retrieval-Augmented Generation (RAG) pre efektívnu analýzu správania malvéru. Začína prehľadom metód analýzy malvéru, ako statických tak dynamických. Štúdia sa zameriava na využitie rámca MITRE ATT&CK na pochopenie správania malvéru veľkým jazykovým modelom. Jadro výskumu sa zameriava na architektúru a implementáciu nástroja na analýzu správania malvéru, ktorý implementuje RAG s využitím LLMs. Tento nástroj má za cieľ pomôcť profesionálom v oblasti bezpečnosti využívať možnosti generatívnej AI na interpretáciu komplexného správania malvéru. Okrem toho, výskum zahŕňa praktické nasadenie systému pre správu bezpečnostných informácií a udalostí (SIEM), pričom využíva platformu Wazuh na detekciu simulovaných útokov. Nasadenie a testovanie prebiehajú v kontrolovanom virtuálnom prostredí. Práca poukazuje na potenciál LLM modelov pri zlepšovaní opatrení v kybernetickej bezpečnosti. Práca končí diskusiou o možných vylepšeniach implementovaného nástroja.

Study of profile of refractive index structure parameter in atmosphere
Aubrecht, Ondřej ; Grábner,, Martin (referee) ; Hudcová, Lucie (advisor)
This work is dedicated to structural parameter of the refractive index in the atmosphere Cn2 and his various models. For comparison the models are simulated only for one area and only for one day. The work represented the influence of atmospheric turbulence on the communication environment and on the individual models. In addition this work is for selected areas and for the input conditions created program for modeling of structural parameters and meteorological data in the atmosphere

IMPACT OF STRATEGIC MANAGEMENT ON THE PROSPERITY OF THE COMPANY
Palíšek, Eduard ; Bartes, František (advisor)
The target of this dissertation thesis is to verify a relationship between strategic planning and prosperity of the company. Opinions of many experts about expediency of strategic planning vary. Some believe that strategic planning is a base for successful growth, while others demonstrate through results of many different researches that a direct relationship between strategic planning and success of the company cannot be proven. Therefore an empirical research was made to test hypotheses about the impact of strategic planning on prosperity of the company. The theoretical part of the thesis describes the development of strategic management followed by a description of internal and external business environments and the impacts which influence them. The theoretical part also describes the characteristics of strategic management and planning, tools and models as well as methods for measurement of efficiency of strategic planning. As the sub-target of this thesis is also to propose a simplified model of strategic planning which could be applied in small and medium size companies, the theoretical part is concluded by description of specifics of small and medium size companies. The analytical part of the thesis consists of detailed analyses of data collected through questionnaires. Based on results of those analyses, profiles of different categories of companies are synthesized. Conclusions of performed analyses and syntheses are used as a base for testing of validity of defined hypotheses. A new concept of the “4-segments model” of strategic planning is presented in the proposal part of the thesis. Benefits for theory and for practical use are evaluated at the end of the thesis.

Simulation of Electromechanical System Control Structures
Petruška, Ľubomír ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
Construction of motor models is the main topic of this project. Mathematical characterization of AC machine, permanent magnet synchronous motor, separately-excited DC motor, series-wound DC motor, permanent magnet DC motor, switched reluctance motor is also described. Design of models is based on mathematical description of particular motors. Models are created in Matlab Simulink. Each model is implemented in continuous and also in discrete time variant. Selected models are implemented also on processor from Freescale 56F800E Hybrid Controller family. Each model has individual graphic user interface. Besides motor models, there is description and easy algorithm of Space Vector Modulation. Model of this method is also created. Models are build-up into a library, which can be used for simulations and tests of control structures. Results of models simulations are presented at the end of this project. Simulation of models that are implemented on processor is also made in Matlab Simulink environment and is compared to simulation of models that are implemented directly in Matlab Simulink.

Cloud Solution for 3D Models Processing
Klemens, Jakub ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This thesis deals with the possibilities of processing 3D models in cloud applications. A C++ library called Cloud3D has been designed and implemented. The resulting library is used to quickly create client-server applications. The library is divided into three separate parts: Client, Service Provider and Load Balancer. The service provider runs in the cloud and provides 3D model processing services to client applications. The biggest advantage of Cloud3D is the ease of creating new applications with its help. Other benefits include scalability, assured implementation of look-a-side Load Balancer, and security ensured by the use of SSL certification.

SCADA system for operator control of decentralized PLCs stations
Ferjančič, Michal ; Karel, Janda (referee) ; Pásek, Jan (advisor)
This bachelor’s thesis deals with the creation of a comprehensive SCADA systemWinCC flexible development environment. Process kontrol is ensured by the PLC S7 – 300 Communication between the PLC andthe PLC and SCADA system is secured by an industrial Ethernet. The nodes of the technological proces is realized through physical models. The models perform simple actions. The model of balls calculates balls in the cylinder and you fall off the box. The model dril is able to pierce the workpieces in two sizes. Model of sorting belt classifies material by size. Each model uses for its management of a PLC. Control of each models is made from the controls in the models keys or the numerical rotary adjusters.
