GLASS, LIGHT, OPTICS
Ilič, Andrej ; Fulínová, Katarína Kudějová - (referee) ; Tobola, Ondřej (advisor)
The bachelor thesis deals with the development of a glass pendant interior light. The author utilizes optical principles to achieve the desired lighting effect while contextualizing the piece within an interior space. The light design is conceived as a modular system, enabling the customer to assemble multiple units as a construction kit. The result of the thesis is a prototype ready for mass production.

The potencial of next-generation probiotics
Kharkevich, Viktoryia ; Langová, Denisa (referee) ; Trachtová, Štěpánka (advisor)
The aim of the bachelor thesis was to examine the possibilities of identifying probiotic microorganisms using molecular diagnostic techniques such as PCR and HRM-PCR in a commercially available product – Probiolact Forte 12. In the theoretical part, a literature review focused on next-generation probiotics was conducted. In the practical part, cultivation of microorganisms contained in one capsule in liquid medium and solid media was performed. DNA isolation was carried out using the NucleoSpin Microbial DNA commercial kit according to the manufacturer's instructions. The purity and concentration of isolated DNA were verified using spectrophotometric analysis. Primers for specific PCR analysis of DNA domains Bacteria and individual genera and species, whose presence the manufacturer declares in the preparation, were used for DNA identification. The results of the PCR analysis confirmed the presence of the target DNA, i.e., bacterial genera and species in the preparation, as claimed by the manufacturer.

Microbiome of smear ripened cheese and its changes in dependence on the stages of production
Jandová, Karolína ; Mikešová,, Martina (referee) ; Trachtová, Štěpánka (advisor)
The theoretical part describes soft smeared cheeses, then deals with the technology of manufacturing said cheese with importance on the development of microbiome and describes the most commonly wanted microorganisms and contaminants. Shortly also deals with legislation requirements on the microbial quality of these chesses. The experimental part studies the development of microbiome and contamination by fungi of soft smeared cheese. Firstly, samples were collected in manufacture from each step of manufacturing. In the first part, microbial and microscopical assessment was done. In the second part, DNA was isolated from samples by a commercial kit and phenol-chloroform extraction. The concentration and purity of isolates were determined by spectrophotometry. By qPCR of the DNA isolates the main microbiome and contamination by fungi were examined. As part of the microbial and microscopical assessment, the expected bacteria were determined, and several species of yeast were found, instead of the expected one. Mold contamination was also found. Using molecular diagnostic techniques, the presence of bacteria, yeasts, fungi and the genera Brevibacterium and Candida was proved.

Development kit for capacitive touch sensors analysis
Večeřa, Marek ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This bachelor thesis adresses the topic of capacitive touch sensing for use in electronics with evaluation on dedicated microcontroller peripheral, or on a dedicated integrated circuit. At first there are presented various ways of capacitive sensor design and their evaluation methods. Secondly in practical chapter I introduce a design of development kit with implementation of different capacitive elements on the STM platform, whose sensitivity and efficiency is evaluated and compared to integrated circuit dedicated to capacitive sensing.

Evaluation of the presence of probiotic bacteria in a food supplement using molecular biological methods
Dvornyi, Nikolai ; Brázda, Václav (referee) ; Smetana, Jan (advisor)
Probiotics are beneficial microorganisms that, when administered properly, can provide health benefits to the host, such as aiding digestion and boosting the immune system. Their effectiveness and benefits depend on the specific strain of microorganism. These strains are often from the genera Lactobacillus, Bifidobacterium, and represent natural hosts of the gastrointestinal tract. This bachelor thesis focuses on the identification of probiotic bacteria in a commercially available dietary supplement Linex® Forte using molecular biological methods, mainly polymerase chain reaction (PCR). The aim was to verify the presence of the claimed probiotic cultures of Lactobacillus acidophilus, Bifidobacterium animalis, and to compare the results with the manufacturer's claims. Therefore, two DNA isolation methods were used: phenolchloroform extraction and the commercial purification kit OMNI International. The isolated DNA was then analyzed by domain, genus and species-specific PCR. The results show that the methods used are suitable for the identification of probiotic bacteria and confirm their presence in the selected product.

Multimedia Extraction from Hard Disk Images
Csáder, Lukáš ; Koutenský, Michal (referee) ; Pluskal, Jan (advisor)
This work addresses the issues of computer forensic analysis and its essential role in the detection, analysis, and recovery of digital artifacts. The main objective is the identification, extraction, and documentation of multimedia artifacts with the aim of providing an automated tool for this purpose. The paper discusses the possibility of interoperability of The Sleuth Kit library in the .NET environment and the integration of the PhotoRec Carver tool into the Maxtor application. An important part is the creation of a custom testing dataset, which includes various file systems and deformations. The achieved results of testing are discussed with respect to their effectiveness in the proposed scenarios. The benefits and possibilities of this tool in the field of digital forensic analysis are evaluated.

Library creating in Matlab/Simulink for sensors of Lego Mindstorm
Kovařík, Michal ; Doskočil,, Radek (referee) ; Křivánek, Václav (advisor)
his bachelor's thesis is a detailed analysis and communication with selected sensors from HiTechnic. The sensors are both digital and analog and offer a wide range of applications in robotics. They are designed for the Lego Mindstorms NXT 2.0 kit and they are compatible with the Lego Mindstorms EV3 kit used here. Selected sensors include a compass, gyroscope, accelerometer, barometer, force sensor, tilt sensor, and various types of infrared sensors. The content of the thesis includes a detailed description of the sensors and the method of communication with them. The result is the implementation of controllers for individual sensors in the Matlab and Simulink environment. Sample measurements with sensors were performed to verify the functionality of the controllers. The created controllers can be further utilized for education in the field of programming or automation.

Problems of drum kit players from the perspective of physiotherapy
KOŠNEROVÁ, Barbora
The bachelor's thesis is dealing with the players of the drum set, primarily musculoskeletal disorders that bothers them. Because all musculoskeletal disorders couldn't fit in this thesis, the most important ones were chosen. The most problematic part of a body was chosen with help from a questionnaire using a pain assessment. Then, all the musculoskeletal disorders related to this part of a body were analyzed. The thesis is divided into a theoretical and practical part. The theoretical part is dealing with drum set, techniques of playing the drum set, kinesiology, the most common musculoskeletal disorders and their prevention. The practical part is done by form of mixed research. The quantitative element is a questionnaire to which 250 probands answered. The questionnaire was posted for three months - from August to November and on Facebook groups for drummers. The following research includes case studies of three probands selected from the questionnaire. Each proband underwent six therapies over a period of three weeks. At the same time, in these three weeks, they did the same exercise unit and were educated about ergonomics while playing. An initial examination was done during the first therapy, and an exit examination was performed during the last one. It is evident from the results of the questionnaire that the most problematic part of body from the examined group is the low back. That is why the rest of the research was focused on it. At follow-up research, there was an improvement in low back pain in all probands. It can therefore be stated that compensatory exercises, stretching and following the ergonomics of the seat and setting the drum set are important for drummers. The results of this thesis could be used as an educational material for drummers and drum teachers.
