Sensorimotor difficulties in children with speech impairments
Hodačová, Alžběta ; Vařeková, Jitka (advisor) ; Majorová, Simona (referee)
Title: Sensorimotor difficulties in children with speech impairments Objectives: The main aim of the thesis is to assess sensorimotor functions of children with speech disorders using standardized test batteries. Methods: 27 children were part of the study (21 boys, 6 girls), all with speech disorders from an elementary school in the age range 11-15 (12,4 years±1,05). Motor skills were tested with data collection testing batteries MABC-2, Unifittest 6-60. Furthermore, sensory functions were tested using the Nottingham Sensory Assessment. Probands were also provided with a supplementary questionnaire to gather additional information. In the next step a data matrix was created in Microsoft Excel where all data were input. Data analysis was conducted using programs Microsoft Excel and Jamovi. Results: Children with speech disorders showed higher prevalence of motor difficulties compared to Czech norms. According to the overall STS score in MABC-2 test, 63 % (17) were in the range of significant motor difficulties, which is 13 times higher than the norms. A statistically significant relationship between the Unifittest and MABC-2 was proven.In addition, a positive correlation was also confirmed between the BAL component of the MABC-2 and the long jump task in the Unifittest 6-60. Among the sensory...

Design of DC motor for teaching
Hajdú, Zsolt ; Huzlík, Rostislav (referee) ; Vlach, Radek (advisor)
The topic of this bachelor thesis is Design of DC motor for teaching. The main goal of this bachelor thesis was to create an electric motor that uses direct current, commutator brushes, and permanent magnets to generate torque. Another goal of this bachelor thesis was to achieve 50W of power at 100rad/s. We also set a secondary goal to achieve 50% efficiency across the entire speed range. To create the theoretical model, we used Fleming's right-hand rule. Using this principle and based on calculations, we constructed the motor. The main power source was a car battery. After constructing the motor, we measured its parameters and compared the obtained values with the theoretical ones.
