The thesis focuses on how different languages influence spatial cognition of their speakers, i. e., whether and how the differences in spatial language (linguistic representation of perspective, location, spatial scenes etc.) affect the non-linguistic spatial reasoning (orientation, spatial memory etc.). This issue has for a long time been a part of the studies of the relation between language and thouhgt under the flag of so called Sapir-Whorf hypothesis/Hypothesis of linguistic relativity. In the first half of the theoretical part of the thesis, I attempt to summarize the history of the concept of linguistic relativity since 1950s and to revise some critical claims about linguistic relativity by re-reading Whorf's works (chapter 2). The second half of the theoretical part (chapter 3) focuses in particular on the research of the interrelations between spatial thought and language. In section 3.1, I make a brief note on the notion of space in terms of cognitive linguistics. Section 3.2 provides an selective overview of the previous research of the crosslinguic spatial-cognitive diversity. Sections 3.3 and 3.4 connect the theoretical and the empirical part of the thesis. The research itself is presented in the chapter 4. It experimentally tests the hypothesis, that the language-specific...

This master's thesis deals with acceleration of geometrical image transforms using the GPU and NVIDIA (R) CUDA TM architecture. Time critical parts of the code are moved on the GPU and executed in parallel. One of the results is a demonstrational application for performance comparison of both architectures: the CPU, and GPU in combination with the CPU. As a reference implementation, there are used highly optimized routines from the OpenCV library, made by the Intel company.

The presented work is concerned in system of automatic tools change for machining centers. The theoretical part of this diploma work is about basic distribution. The following practical part includes mathematical description of testing stand of systems of automatic tools change STD – 25. In next step the dynamic model of this mechanism and model of servomotor is realized using simulating environment as Matlab/Simulink. The simulation of designed model of complete system is optimized in aspect of rate of change. The obtained values of servomotors performance are compared for various loads of exchange arm at the appropriate times of change. The last section briefly describes other possible alternative solution of similar dynamic systems using connection of software SolidWorks and NI LabView.

This thesis deals with mechanical and fatigue properties of magnesium alloy AZ91 processed by EX-ECAP method. This method involves the application of extrusion followed by equal-channel angular pressing. To obtain basic mechanical characteristics, the tensile test were carried out at room and elevated temperatures. Further the fatigue tests were performed and obtained data were used to compile S-N curve. The work also includes metallographics analysis of microstructure and fractographic analysis of fracture surfaces of tensile and fatigue test specimens.

This thesis focuses on measurement of anatomical parameters of lower limb in patients with non-traumatical anterior knee pain. Theoretical part of this work describes basic anatomical, kinesiological and biomechanical knowledge about lower limb. Also there are described basic non-traumatical pathologies of knee and how to assess them. Methodology: in experimental part there were examined and measured these parameters: Q angel, foot pronation and range of hip rotation of 28 sportsmen, of which 7 had unilateral anterior knee pain and 4 had bilateral anterior knee with no previous traumatic experience of the knee. Assessing of angles was made through photographic goniometry using Adobe Illustrator to measure angles on digital pictures. Results: the work did not confirm any of hypothesis, that a statistically significant deviation would be found in patients with anterior knee pain compared to heathy population in at least one of the measured parameters. However further analysis of measured data showed statistically significant correlations between foot pronation and range of internal hip rotation and Q angle and range of external hip rotation both in patients with anterior knee pain compared to healthy population where no such correlation was found. Conclusion: This work suggests existence of connection between...

Title: Effect of the range of the shoulder joint rotation in volleyball players on the development of functional changes. Objectives: The aim of this thesis is to confirm the presence of the glenohumeral internal rotation deficit in beach volleyball players and to determine whether it affects the development of functional changes of the shoulder joint located in the dominant upper limb. Methods: The thesis was a quantitative study with the character of an experiment. There were 60 active volleyball players aged 18-30 years who were deliberately selected for the purposes of the study. The essence was to ascertain whether GIRD affects the pain in the shoulder joint of volleyball players and whether it was deemed positive for all participants of the study. In order to examine the range of motion, the goniometer in the external and internal rotation according to Janda and Pavla, Janda and Sachse was used, as well as hypermobility tests and a shoulder joint pain questionnaire. The statistical data processing was performed by Microsoft Excel 2010. The sum and average functions were used. Subsequently, graphs and tables were created from the results Results: The established hypotheses were confirmed in two cases. GIRD is determined positive for beach volleyball players. From the results of hypermobility...

The thesis addresses the instabilities in stock markets in the USA. There are many factors that may increase the price volatility, or even cause a panic. During these turbulent times investors can seek shelter in investment safe havens that allow protecting their portfolio against significant financial losses. The focus is put on identifying the situations where it is appropriate to use the safe havens and how to properly time all transactions. Historical insight, events study and investigating economic cycles are the integral part of the work.

The thesis is about static analysis of moving skyscraper (inspired by The Dynamic Tower). There is a rotation of each particular floor around its axis independently on each other. In this thesis, moving skyscraper is solved as a whole piece with specialization in the moving floors and their mounting on the core of the building.

Tato diplomová práce má za cíl seznámit čtenáře se stále ještě relativně novou a neznámou oblastí matematiky, s geometrickou algebrou. Nejdříve jsou uvedeny základní definice a poté jsou studovány vlastnosti obecné geometrické algebry. Další velká část textu se věnuje Konformní geometrické algebře, která je v současnosti jedna z nejvíce zkoumaných a aplikovaných geometrických algeber. Jsou popsány její algebraické a geometrické vlastnosti, konkrétně schopnost reprezentovat určité geometrické objekty jako vektory. Taktéž umožňuje počítat jejich průniky a konformní transformace. Další část textu je zaměřena na aplikace Konformní geometrické algebry, nejdříve k popisu kinematiky robotické ruky a poté v binokulárním viděni.

This thesis deals with facial recognition using convolutional neural networks and with their current problems, which are pose, lighting and expression variance. It summarizes existing approaches, architectures and most recent loss functions. Further it deals with methods for rotating faces using GAN networks. In this thesis 3 neural networks are designed and trained for facial recognition. The best of them achieves 99.38% accuracy on LFW dataset and 88.08% accuracy on CPLFW dataset. Next face rotation network PCGAN is designed, which can be used for face frontalization or data augmentation purposes. This network is evaluated on Multi-PIE dataset and using the face frontalization it increases identification accuracy.
