Control of External Devices on macOS to Prevent Data Leaks
Zuzelka, Jozef ; Veselý, Vladimír (referee) ; Pluskal, Jan (advisor)
Práca sa zaoberá problematikou kontroly a blokovania externých zariadení v operačnom systéme Apple macOS za účelom ochrany pred únikom citlivých dát. Implementované riešenie ukazuje zvolené prístupy pre blokovanie externých a cloudových diskov. Pre blokovanie USB diskov bol použitý DiskAbitration framework, čo je najvodnejšie riešenie tohto typu úlohy. Avšak cloudové disky sú v skutočnosti synchronizované zložky a úlohu nehrajú ovládače ani strom pripojených zariadení. Ku kontrole operácií v cloudových diskoch bol použitý Endpoint Security framework. Aktuálne podporovaní cloudový poskytovatelia sú iCloud a Dropbox a prístup k nim môže byť obmedzený úplne alebo iba na čítanie. Schopnosť synchronizácie vzdialenýh zmien bola zachovaná avšak v prípade Dropboxu si to žiada nepoužívať ich aplikáciu na správu súborov.

Factors affecting stability and consumer acceptance of sauerkraut water
Vašků, Barbora ; Mikulíková, Renata (referee) ; Márová, Ivana (advisor)
This diploma thesis is focused on the optimization of pasteurization of the cabbage juice in order to extend its shelf life. The theoretical part is focused on the description of the sauerkraut production technology and characterization of the main components of fermented cabbage and its juice, it also deals with pasteurization options and presence of probiotic strains. In the experimental part, the composition of the brine was analyzed from a chemical point of view (bioactive substances, sugars, carbohydrates), from a microbiological point of view (presence of probiotics, pathogenic organisms) and the effect of selected pasteurization processes on these components. Pasteurization at 90 °C for 0.5 minutes was determined as the most suitable treatment, during which potential pathogens are being eliminated, while most of the original bioactive components are preserved. After suggesting the effective pasteurization treatment, suitable species of genus Lactobacillus was selected to enrich the cabbage juice product because of decreasing of probiotics viability during pasteurization treatment. The strain Lactobacillus plantarum was determined as the most suitable probiotic species for cabbage juice enrichment, due its ability to survive in 2 weeks storage at 8 °C in cabbage juice. Chemical composition after 2 weeks of incubation with mentioned organism has changed. Quantity of lactic and acetic acid increased, while no changes in content of vitamin C were observed. Finally, sensory analysis was performed to evaluate suggested mixed fruit-vegetable drink. According to results of sensory analysis, the drink composed of cabbage juice and apple-beetroot juice in the ratio of 2:1 was found as the most acceptable.

Apple iOS security
Zahradníček, Zdeněk ; Martinásek, Zdeněk (referee) ; Hajný, Jan (advisor)
Bachelor´s thesis deals with the iOS operating system security and creating applications for this system. Describes the basic features of the system, security, encryption, and classes for secure file storage. Another area that deals with the work is that access to the Internet and the protection of transmitted and received data. The work is described Xcode programming package, used by developers for iOS platform. Furthermore, the compiled application to examples of work with this programming package and its subsequent testing in a virtual device simulator which is part of this package. I did application that uses large numbers of 1024bit value and then use these numbers for calculations. The output of application was average time of measuring duration of calculating the mathematical operations.

Multi-User Cooperation in Augmented Reality on iOS
Jurczyk, Adam ; Kapinus, Michal (referee) ; Beran, Vítězslav (advisor)
The aim of this work was to create a solution that would allow multiple users to cooperate in a shared Augmented Reality environment. The proposed solution enables users to interact and edit a 3D scene in real time. Thesis touches on the subject of how a user interface should look like to assist with synchronization of devices in the shared scene. It also describes a system for user permission and action conflict resolution when dealing with virtual object interaction. A hybrid peer-to-peer architecture is designed to facilitate communication between individual peers. The solution is based on the iOS platform and uses the new functions available in the ARKit 2 framework. The resulting application is used to demonstrate and evaluate how the designed systems perform during multi-user cooperation. The designed solution can be used as a basis for an application that presents work from a designer to a client with the ability to get expressive user feedback in real time and in the intended physical environment.

iPhone Application for Number Plate Recognition
Sládeček, Roman ; Dvořák, Radim (referee) ; Procházka, Boris (advisor)
This thesis talks about theoretical and practical side of development of application for Apple iPhone mobile cell phone and for its operating system called iOS. In theoretical part are contained informations about history of this device, about tools for creating application for this mobile platform and there is shortly sketched procedure and process how the application is deployed into the phone. Next part deals with the licence number plates, their signification and integrity restrictions. Main core of whole thesis is a practical part about creation and implementation mobile application for recognition of that number plates with supporting of built-in camera and its consecutive text representation or manipulation with that data. In the final part there is a review of results which this application brings after testing and experimenting in different conditions.

Influence of storage conditions on content of biologically active substances in apple fruits.
Ferdová, Jitka ; Čarnecká, Martina (referee) ; Márová, Ivana (advisor)
This study deals with antioxidants in diet and their effects on human organism. Further, it summarizes the agents affect the quality of apples in the course of long-term storage and it outlines the possibility of defence against them. In the experimental part methods of determination of antioxidant enzymes superoxid dismutase (SOD), catalase and polyphenol oxidace (PPO) in apples were introduced. The enzymes were measured in apples tissues in liquid nitrogen after 158 days in normal or modified atmosphere. In Apple the quantitative and qualitative analysis of proteins was realized. Further, some low molecular antioxidants (total phenolics, total flavonoids and vitamin C) as well as total antioxidant status were measured in frozen raw juice. This values were compared with values from apples analyzed immediately after the harvesting. Artificial inoculation with fungi was made in the last part and the fruitfulness was observed.
