Stereometric ultrasonic distance sensor
Nguyen, Thuc Tuyen ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This bachelor thesis deals with designing and realizing a sensory system for detecting the presence of targets and its location. Target is located by two parameters: the distance and the view angle from sensory system. This system is set up by two ultrasonic distance sensors SRF02, driven by microcontroller Atmega128, using I2C communication protocol. The placement of the two ultrasonic distance sensors is optimized by using mathematical model, it enables the system to perform optimum accuracy and be able to observe the largest area possible. The measurement results then will be shown on LCD display module or they can be saved and used as input parameters for other tasks.

Porovnání úrovně a vyváženosti vypsaných národních a mezinárodních drezurních úloh za použití měřícího zařízení Equimo tracker
Zourková, Barbora
This diploma thesis is entitled Comparison of the level and balance of the listed national and international dressage tests using the Equimo tracking device. Its goal was to get information about dressage tests. Their duration, distance, symmetry in each gait, and calories burned were observed. Twelve dressage tests were chosen from five levels of difficulty Z to T. Each test was registered three times. All testing was performed by one rider on one horse using the Equimo device. In general, it could be evaluated that, from the point of view of duration, distance, and calories burned, the degrees of difficulty Z and L were very similar, followed by S, ST, and T. The most extreme differences were found in the symmetry of the sides for the DU-A test and the duration of the Z4 test.

Effect of distance from the plant on the intensity of interaction between plants and soil
Skydaniuk, Liudmyla ; Münzbergová, Zuzana (advisor) ; Mudrák, Ondřej (referee)
The concept of plant-soil feedback is increasingly used to explain plant-community interactions. As plants grow, they change the conditions in the surrounding soil environment. These soil changes affect further plant growth. We call this effect plant-soil feedback (PSF). The effect of PSF is typically studied directly in the place where the plant grows. How far from the plant this effect can be, however, is little explored, but this knowledge is important for understanding the structure of plant communities. The main goal of thesis was to investigate the effects of the distance from the plant on the intensity of intraspecific and interspecific feedback between the plant and the soil. The research was conducted using a classic, two-phase experiment. Four species were selected for the research, forming two pairs of one grass and one broad-leaved herb each time. The first pair were Bromus erectus and Inula salicina occurring naturally on dry lawns in northern Bohemia. The second pair were Calamagrostis epigeios and Daucus carota, occurring on lignite dumps in Sokolovsk. The species were cultivated during the cultivation phase in the soil of their origin, it means the soil of the dry lawn of northern Bohemia or the Sokolovsk dump, either each species of the pair was cultivated separately or both...

Measurement of calibration inductance parameters
Martišek, Jiří ; Fialka, Jiří (referee) ; Šedivá, Soňa (advisor)
This thesis deals with the problem of measuring the properties of coils and their inductance dependence on frequency under the influence of an external magnetic field. The theoretical analysis of the properties, parameters and behaviour of the coils is included. Furthermore, the theoretical part describes the measurement methods and instruments for measuring coils and their parameters. The third chapter is devoted to the Caliber program from Meatest, s.r.o., which can be used to automate both calibration and measurement. The practical part describes the selection of the coil measurement method, the selection of the tested commercial coils and the creation of the procedure in the Caliber program. The rest of the thesis describes the measurement procedure, processing of the measured values and evaluation of the measured results.

Theorizing Military Power Projection: Why and When Distance Matters
Bahenský, Vojtěch ; Kučera, Tomáš (advisor) ; Doboš, Bohumil (referee) ; Badsey, Stephen (referee)
The relationship between physical distance and military power is oft-discussed and even more often assumed but arguably still poorly understood. Despite the scope of existing research on the relationship, there is little agreement on the causal mechanism connecting the two variables in question, which hampers further examination of the phenomenon. This work attempts to fill this gap by asking how and when does distance actually matter for military power projection. By connecting International Relations research on the subject with strategic and military studies understanding of the underlying processes and through an in-depth case study of the Falklands War, the thesis identified three general causal mechanisms which mediate distance's detrimental effect on military power: temporal mechanism, contestation mechanism, and materiel mechanism. Additionally, it also found that three mechanisms reinforce each other but generally are not causing additional military power decay in the presence of other conditions limiting war. The thesis argues that distance plays only a minor role in very small deployments into limited conflicts, but this should not be generalized lightly to possible great power wars by using quantitative methods. Possible policy implications of the theory for the United States and its...
