Development of technologies for 3D printing of concrete structures
Roupec, Josef ; Hela,, Vlastimil (referee) ; Hela, Rudolf (advisor)
Subject of dissertation was to itemize testing methods in fresh and hardened state of cement paste or concrete. During this process some new testing methods and specimen creation protocols were proposed. Further was created list of used materials and mix design processes which led to list of used 3D printing mixture designs and 3D printers. Next part of dissertation was devoted to creation of 3D printing mix design and observations based on them. At~the end is proposed a radical change in testing methods which utilizes latest advancements in computer science and could be part of digital design process for construction.

Quadcopter localization in 3D space based on mono-camera
Kubica, Petr ; Musil, Petr (referee) ; Beran, Vítězslav (advisor)
This bachelor thesis focuses on the possibilities of existing methods for locating the UAV AscTec Pelican using a monocular camera. The methods SVO, PTAM and LSD-SLAM were tested in both inner and outer environments using various cameras, lenses and hardware with different performance. Based on the experience gained during the testing, guidelines on how to achieve the best results are made.

Design for testing device used to measure air leakage from linear pneumatic actuator
Kurillová, Katarína ; Tůma, Zdeněk (referee) ; Vetiška, Jan (advisor)
This thesis is focused on detecting air leakage in serial production of pneumatic linear actuators. Testing for air leakage is an important part of the production process in which the manufacturer ensures that the product satisfies quality requirements and works correctly. The thesis was created in collaboration with the Czech manufacturing plant of SMC Industrial Automation CZ s.r.o., which produces pneumatic actuators. Goal of the design part of the thesis is to select the most effective method for testing and finding universal principle for testing in specified conditions. The principle is then applied to design a testing device for the CQ2 cylinders. The testing device consists of three parts - pneumatic circuit, control circuit and electric circuit. Thesis conclusion contains comparison of the newly designed testing device with the device currently in use.

Survey and Assessment of Brick Building in Brno, Palacky Street
Španihelová, Ivana ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
The thesis summarizes the methods used to test and evaluate the characteristics of vertical masonry structures and further shows the evaluation procedure according to ČSN ISO 13 822. In the second part of this work there is a practical example of brick building assess-ment process, including determining the strength of the walls and the conversion of select-ed critical elements of the existing structure – window pier and wooden beamed ceiling.

Structural and magnetic properties of Fe-oxide layers prepared by inkjet printing on Si-substrate
Zažímal, František ; Svoboda, T. ; Dzik, P. ; Homola, T. ; Jirásková, Yvonna
Magnetic films with two, four, six, and eight layers were prepared using 2D inkjet printing on the 333 K heated Si-substrates at ambient conditions. The microstructure, phase composition of layers, and magnetic studies were investigated using wide spectrum of experimental methods with the aim to find the optimal conditions for producing magnetic sensors by digital printing technology in the near future. As the magnetic compound, the hematite powder was chosen and its milling with Si-binder dissolved in dowanol using glass balls and vial to prevent contamination was done to prepared suspension appropriate for printing. It is shown that hematite transformed markedly into maghemite, thus the layers consisted of small amount hematite and dominant maghemite phases determining the magnetic properties. From the viewpoint of magnetic behavior, the highest saturation magnetization and the lowest coercivity was obtained at the sample with 8 layers.

Determining the most common functional disorders of the musculoskeletal system of primary school children, particularly in the 1st and 2nd grade at elementary schools in Strakonice
KOVÁŘOVÁ, Veronika
In summary of findings we first address problems of correct and poor posture. We present methods how to easily detect function disorders of locomotive system, their basic characteristics, and how to compensate such disorders, or how to prevent them completely. The research focuses on determination of the most common function disorders in children of young school age. Total of 384 children from 1st and 2nd grades of all elementary schools in Strakonice participated in the survey. The following methods were chosen evalutation of posture according to Jaroš and Lomíček, which disclosed that the most common function disorders apply to lower limbs. Testing according to Matthias showed that 33 % of children suffer from poor posture. The research includes a questionaire, which helped us to find out that poor posture occurs less frequently in children who pursue physical activities.
