31	Modelování atmosférické cirkulace exoplanet / Modelling of exoplanetary atmospheric circulation Novák, Jiří January 2014 (has links) In this thesis we study the properties of exoplanetary atmospheres. The first part describes methods and instruments for searching exoplanets, statistics of discovered exoplanets and the sampling factor. The second part describes the properties of chosen planets and moons in the Solar system (Venus, Mars and Titan) and also possible properties of the exoplanetary atmospheres that are only briefly understood. The third part describes the atmospheric models which incorporate full 3D model of the atmosphere, dynamical core, shallow-water model and 1D spherically-symmetric model. We also show the results of exoplanetary atmospheric models published in the scientific journals. This part also describes the icosahedral geodetic grid that is advantageous for the global climatic models, and also discretisation on sphere and the application of the operators (gradient, divergence, vorticity) on geodetic grid. The fourth part discusses results of the numerical solution of the atmospheric circulation with the forcing on geodetic grid. In this part we also show global maps of the variables after a particular time of the numerical integration and also the evolution of the variables at chosen points in time. In the discussion part we examine the results of our program. The results of the numerical integrations (chosen...

34	Propedeutika kartézské souřadnicové soustavy a rozvoj funkčního myšlení žáků 1. stupně ZŠ / Propedeutics of cartesian coordinate system and the development of functional thinking of primary school pupils Ročák, Štěpán January 2018 (has links) This thesis didactically maps and describes new didactical mathematic environment and the possibilities of its application in teaching in the first grade of primary education. In this thesis I describe the process of an experiment conducted with pupils of the 1st - 5th year of elementary school, with whom I have tried and verified a series of new environment exercises. Based on the reflection of this experiment, and the analysis of pupils' solutions, I formulated a final version of these exercises. I led the process of the whole experiment in line with the constructivist educational style. In the theory part, I am mentioning the important terms of mathematics and its didactics, that are necessary for the purposes of this thesis, and that I refer to the relevant professional literature. This thesis also contains the analysis of chosen textbook collections that are related to its topic. The last part of this thesis is the final and complete series of exercises useful for teaching mathematics in the 1st grade of elementary school, especially if the teacher aims to purposefully develop the pupils' understanding of the terminology and relations from the mathematical areas of analytic geometry, functions and sequences.
35	Měření vzdáleností mezi stanicemi v IP sítích / Distance measurement between nodes in IP networks Šimák, Jan January 2010 (has links) This thesis deals with delay prediction issue between nodes on the Internet. Accurate delay prediction helps with choosing of the nearest internet neighbor and contributes to effective usage of network sources. Unnecessary network load is decreased due to algorithms of delay prediction (no need for many latency measuring). The thesis focuses theoretically on the three main algorithms using coordinate systems - GNP, Vivaldi, Lighthouses. Last one is at the same time the main subject of the thesis too. Algorithm Lighthouses is explored in detail theoretically and in practise too. In order to verify the accurate of delay prediction of Lighthouses algorithm the simulation application was developed. The application is able to compute node coordinates of synthetic network using Lighthouses algorithm. Description of simulation application and evaluation of simalution results are part of practice part of this thesis.

The mathematic model of flow inside meridional section of impeller and spiral is based on the instruments of differential geometry applied to Bezier surfaces. This formerly introduced theory is more deeply developed in this thesis and the conclusions are applied to the design of centrifugal pump parts working with fluid. The main thesis output is the mathematic model and on its principles created software determined for the design of impeller, blade and spiral. The received results are exportable into one of the commonly used 3D modeling programs.
37	Vlastnosti geometrie prostoročasů v blízkosti horizontu / Properties of near-horizon geometry of spacetimes Daněk, Jiří January 2013 (has links) Nowadays, the near-horizon regions of black holes have enjoyed great attention thanks to their role in the popular AdS/CFT correspondence and their specific geometry suitable for formulations of uniqueness theorems in higher dimensions. A strictly general-relativistic point of view reveals also many interesting phenomena taking place near black-hole horizons. Our aim was to investigate how horizon multiplicity affects near-horizon geometry, geodesical distance, radial motion of photons and massive, charged particles, and also the possibility of collision processes leading to unbound collision energies near the horizon. We chose the Reissner-Nordström-de Sitter metric, which, on the one hand, is simple thanks to being static and spherically symmetric but which, on the other hand, is rich enough to enable the existence of up to a doubly degenerate ultra-extreme horizon. After discussing the physical feasibility of the near-horizon limit, we applied it to single, double, and triple horizons, their near-horizon geometries, and local collision processes. We found continuous coordinate systems covering all types of horizons and analytic solutions for motion of radial photons and special or critical, massive, charged particles in their vicinity. We addressed particle collisions in the immediate vicinity of horizons...

A construção do sistema de coordenadas depende crucialmente da noção de simultaneidade associada ao referencial. No entanto, não existe uma maneira natural, ou privilegiada, de definir simultaneidade para referenciais não inerciais, mesmo no espaço-tempo de Minkowski. Cada procedimento conduz a diferentes sistemas de coordenadas. Neste trabalho, discutimos alguns métodos bem conhecidos da literatura especializada. Estudamos as coordenadas de Rindler, de Fermi-Walker, as coordenadas de Radar e as coordenadas de Emissão (ou GPS). O sistema de coordenadas de Rindler é um dos sistemas de grande destaque porque permite simular algumas propriedades da geometria do Buraco Negro num espaço-tempo plano. As coordenadas de Rindler estão associadas a uma família de observadores uniformemente acelerados que obedecem à relação a=1/ρ, onde a é a aceleração própria do observador e ρ a sua posição inicial com respeito a algum sistema de referência inercial. Neste trabalho, propomos um método para construção de sistemas de coordenadas adaptados a observadores cuja a celeração depende da posição inicial segundo a regra a=a0/ρn, onde n ∈ N e a0 é uma constante, usando o princípio da localidade. O caso n = 1 recupera as coordenadas de Rindler. Os outros casos nos permitem discutir a relação entre a geometria não-Euclidiana das secções espaciais e referenciais acelerados,como originariamente proposto por Einstein. Além disso, com a generalização podemos simular o comportamento de observadores estáticos tanto nas proximidades do horizonte de um Buraco Negro (n=1) quanto em regiões afastadas (n=2). / The main role of a coordinate systein is to localize the event-s of spacetime with respect to a frame of reference. The construetion of a coordinate systein depeuds crucially on the notíon of simultaneity associated to the frame of reference. However, there is no natural manner of defining simultaneity adapted to non-inertial frames of reference, even in the case of Minkowski spacetime. Each procedure leads to different coordinate systems. In thls work. we discuss some well-known methods found in the Literatura. We study the Rindler coordinates. Fermi-Walker coordinates. Radar coodinadates and Emission (or GPS) coordinates. The system of Rindler coordinates has great interest because it simulates in a flat spacetime some aspects of a Black Hole's geometry. We can say that Rindler coordinates are adapted to a family of uniformly accelerated observeis which obey the relatiou a = i, where a is the proper acceieration and p is the initial position with respect to some inertial system. In this work, we also propose a method in order to construct coordinate systems adapted to observers whose accelerations depend on the initial position according to the formula a = where n e N and a» is a constant, by using the locality principie. The case TI = 1 reproduces the Rindler coordinates. The other cases allow us to verify a connection between non-Euciideaii geometry of the spatial sections and non-inertial frames of reference, as it was originally suggested by Einstein. With this generalization we can also simulate the behavior of static observers in the vicinity of a Black Hole"s Horizon (TI = 1) and also in distant regions (n - 2) Física.

40	Individual Approaches in Rich Learning Situations Material-based Learning with Pinboards Katzenbach, Michael 02 May 2012 (has links) (PDF) Active Approaches provide chances for individual, comprehension-oriented learning and can facilitate the acquirement of general mathematical competencies. Using the example of pinboards, which were developed for different areas of the secondary level, workshop participants experience, discuss and further develop learning tasks, which can be used for free activities, for material based concept formation, for coping with heterogeneity, for intelligent exercises, as tool for the presentation of students’ work and as basis for games. The material also allows some continuous movements and can thus prepare an insightful usage of dynamic geometry programs. Central Part of the workshop is a work-sharing group work with learning tasks for grades 5 to 8. The workshop will close with a discussion of general aspects of material-based learning.
