Containerization of Database Detectors
Oberreiter, Michal ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
This thesis deals with containerization of command-line applications including containerization of existing tools for database content analysis. The thesis is a part of Testos platform, which aims at software testing automation. The goal was to design and implement a solution that would be both universally usable for command-line applications and at the same time flexible enough to accommodate database detectors and their specific requirements. Docker was chosen as the containerization platform, on which a management system was built. This system provides both a graphical user interface and an application programming interface. The result allows for easy application management and output retrieval. The primary contribution of this thesis is the streamlining and simplification of running command-line applications with specific dependencies. These features come in form of abstracting the underlying mechanisms and providing a graphical user interface.

Internet of Things Device Based on ZigBee and 6LoWPAN
Halász, Dávid ; Mlích, Jozef (referee) ; Musil, Petr (advisor)
Internet of Things is the latest phenomenon in the computing industry. Even if it has not been completely defined yet, we are already surrounded by various devices connected to the Internet. This thesis project focuses on low cost and low-power wireless solutions and on the on-line backend behind the architecture. At the same time the present work also deals with Cloud Computing which can provide a highly scalable runtime environment for this backend without building an infrastructure. To handle the huge amount of data collected by billions of devices, BigData services could be used in the same cloud space. The project is a collection of the theoretical background of the Internet of Things; so as a result, it provides the reader with an overview of the concept. It also provides a walktrough of the design, implementation and testing process of a complex agricultural Internet of Things solution.

Testing Applications Using Linux Containers
Marhefka, Matúš ; Rogalewicz, Adam (referee) ; Smrčka, Aleš (advisor)
This thesis discusses software containers (Docker containers in particular) as a variant of server virtualization. Instead of virtualizing hardware, software containers rest on top of a single operating system instance and are much more efficient than hypervisors in system resource terms. Docker containers make it easy to package and ship applications, and guarantee that applications will always run the same, regardless of the environment they are running in. There is a whole range of use cases of containers, this work examines their usage in the field of software testing. The thesis proposes three main use case categories for running software systems in Docker containers. It introduces aspects for applications running in containers, which should give a better overview about an application setting within containers infrastructure. Subsequently, possible issues with testing software systems running inside Docker containers are discussed and the testing methods which address the presented issues are proposed. One proposed testing method was also used in the implementation of the framework for testing software running in Docker containers which was developed within this work.

Virtualization of operating systems
Král, Jan ; Malina, Lukáš (referee) ; Komosný, Dan (advisor)
The diploma thesis ’Virtualization of Operating Systems’ deals with a general description of virtualization technology and briefly discusses its use cases and advantages. The thesis also mentions examples of different types of virtualization technologies and tools, including more thorough description of the two technologies used for measurement: Docker and KVM. The second part of this thesis descibes the preparation, installation and configuration of all the tools and services that are necessary for measurement of the influence of the aforementioned virtualization technologies on network services running on the virtual machines, including analysis and discussion of the resulting data. Moreover, a custom application for fully automated measurement of the parameters of network services was created, and is also described in this thesis. The conclusion of this thesis summarizes and discusses the achieved results and acknowledges the influence of virtualization on network services, where the Docker application containers, which are with their low overhead comparable to a "bare" system without any virtualization, managed to achieve much better performance results than the traditional virtual machines on KVM.

Railway (flexible space)
Smržová, Kristýna ; Štěpán, Marek (referee) ; Mléčka, Jan (advisor)
Finding new use for the existing railway tracks, which prove themselves as one of the best ways to carry heavy or sizable load. Therefore they have an ability to carry a space. Verification of merging railway with everyday life. Design of a modular units and modifiable structures. Utilization of modern technologies. Demonstration of a proposal of a design using typical examples of railway structure and its surroundings. Taking advantage of railway tracks, unused train stations, neighboring unused industry grounds etc. Description: New possibilities of using railway tracks and surrounded unused sites. Design of modular structures adapted according to selected areas. Utilization of modern technologies.

Air Cargo
Zeman, Petr ; Chlebek, Jiří (referee) ; Šošovička, Róbert (advisor)
The bachelor thesis looks at the system of air cargo. The first part deals with division of aircraft cargo compartments into classes in accordance with safety rules. The following part describes the usage of air containers and pallets and refers to a possibility of transportation of special kinds of cargo. The main ways of cargo transportation by various kinds of aircraft are explained. Some special cargo aircraft are described in more detail. The last part of the thesis is concerned with ground support. The requirements which have to be supplied by an airport are mentioned and also the technical equipment for handling of cargo.
