Návrh konferenčního stolku

Krenarová, Eliška January 2017 (has links)
This diploma thesis focuses on the design of a coffee table, which is further designated for custom-made or mass production and sale. The thesis is divided into theoretical and practical part. The theoretical part serves as a basis for the practical part as it documents the history of coffee tables and the research of coffee tables in the current market. The practical part presents the actual design process of the particular coffee table starting from the idea, first sketches, the selection of the materials and construction to the visualization of the product, the technical drawing and the budget for the production. This part also takes into account the observations from the theoretical part and tries to apply them in the design.

Městská knihovna v Přerově / City Library of Přerov

Odstrčilík, Viktor January 2012 (has links)
The project is solving problem with Library in Prerov and its location on the site and connection to existing infrastructure. The project can be divided into three parts - urban solutions, architectural design and technical solutions. Urban solutions The area is currently degraded by uncontrolled parking of cars and too much communication. This causes confusion functioning of transport and pedestrians weaving between cars. Vegetation is devastated. Influencing factor is the close proximity to the City Circle, whose importance will increase, if realized "shortcut" towards the main railway and bus station. The proposal aims to improve respectively. build high-quality public space. The library building is defined as a solitaire, a reaction to the complicated and urban neighborhood. Its placed on the Conner for puting there some object of interrest. Communications are in the area reduced. Towards the north west corner of the square is placed park. The composition of park is as organic as a library. Architectural design The shape of the building based on the urban situation and the requirements to define solitary building. First shape was circle that was formed into the shape of an ellipse.Outer shell is made from glass up to ensure connected with outdoor space. Horizontal structure is dividet into two sections. The first floor is public place with cofe etc. The rest of floor space is used for administration and supply. The second floor is only for memebers of library. There is situated all books, study places and storages for books. Library has three departments. Department for adults, department for children and music department. The technical solution The basis of construction of the building are reinforced concrete columns with „extendet head“. These are placed on the base plate with the pilots.

Nová role předmětu v umění objektu a instalace / "New" role of an object in "object art" and "art of instalation"

Holubcová, Klára January 2011 (has links)
Submitted graduation theses offer different views of questions relating to an object (thing) in the "object art". The foundation of the "object art" brought a "new" role of an object. It does mean that the border of an art types are no more close, as well as life and art are now transparent. We can find qualitative changes in a various ways of treatment of an object. I saw these changes in according to four basic criteria: meaning, material, form and function. Another centre line of the text are overlaps of fine art and applied art, which detects common tendences in both spheres.

Pohlavní dimorfismus obličeje a jeho změny při stárnutí / Sexual dimorphism of the face and changes during senescence

Mydlová, Miriama January 2013 (has links)
The human face shape is constantly changing during human life, even after one`s development stop (Hennessy a Moss, 2001; Williams a Slice, 2010). This work applies geometric morphometry method on study of sexual dimorphism of human face through ageing. Sexual dimorphism can be defined as a systematic difference in form between individuals of different sex of the same kind (Samal et al., 2007). Morphological changes, related to the process of ageing of human face, were analysed on data obtained from 3D surface models of human faces using methods of geometric morphometry (Dense Correspondence Analysis, Principal Component Analysis, Shell-to-Shell Deviation) and multivariatel statistics (Scree Plot, Hotelling`s Tš-test, permutational test, MANOVA). The work results indicates that the form (size with shape) and shape of men and women faces significantly change through ageing. Individuals aged between 20-40 years differ in form of the face, however the oldest men aged between 61-82 years differ from women only in shape of the face. The biggest differences in sexual dimorphism are in the middle age category (41-60 years), where there are significant differences not only in form, but also considering shape alone. Key words: ageing, form and shape, geometric morphometry, human face, sexual dimorphism 7

Kontrast života a smrti v díle J. K. Šlejhara / The Contrast of life and death in works of J. K. Šlejhar

Krčálová, Tereza January 2012 (has links)
The thesis focuses on J. K. Šlejhar's literary work from two points of view. The first part introduces Šlejhar's work in the contemporary literary context as a result of a synthesis of new literary styles. In the second part the thesis concentrates on a textual analysis and reconstruction of the author's "artistic world". The first part of the thesis gives insight into the contemporary discussions aimed at revising and redefining the function of art with respect to the new development in society and new human needs. The critical reception of realism and naturalism and the reflection of the then wide-spread adoption of new influences from foreign literatures are also dicussed. To draw a comparison, we quote both period and current studies dealing with J. K. Šlejhar's work. Thereby we want to demonstrate the changing requirements of literature and art and the changing perception of a literary work throughout time. The second part of the thesis comprises the textual analysis of Šlejhar's selected writings from the point of view of semiotic literary theory and the reconstruction of the author's "artistic world". Such approach enables us to draw comparisons to Russian literature of the 19th century, primarily with the works of N. V. Gogol and F. M. Dostoyevsky, and to discover a common basis for both...

Počátky teorie matic v českých zemích (a jejich ohlasy) / Origins of Matrix Theory in Czech Lands (and the responses to them)

Štěpánová, Martina January 2013 (has links)
In the 1880s and early 1890s, the Prague mathematician Eduard Weyr published his important results in matrix theory. His works represented the only significant contribution to matrix theory by Czech mathematicians in many decades that followed. Although Eduard Weyr was one of the few European mathematicians acquainted with matrix theory and working in it at that time, his results did not gain recognition for about a century. Eduard Weyr discovered the Weyr characteristic, which is a dual sequence to the better known Segre characteristic, and also the so-called typical form. This canonical form of a matrix is nowadays called the Weyr canonical form. It is permutationally similar to the commonly used Jordan canonical form of the same matrix and it outperforms the Jordan canonical form in some mathematical situations. The Weyr canonical form has become much better known in the last few years and even a monograph dedicated to this topic was published in 2011.

Moore’s Law appears to be drawing to an end. With it, the assumption that software written today will be more efficiently executed in the future simply due to processors’ evolution is being challenged. On the other hand, parallel applications can still be made more efficient by distributing work among different processors to be executed at the same time, thus reducing overall execution time. To enable parallelization, we must have multiple processor cores. This has led to the popularization of multicore architectures. However, writing parallel applications is not trivial. A program must be either written from the start to be executed in parallel, or later adapted for parallel execution. The programmer has the error-prone task of parallelizing the application through use of concurrency and parallelism constructs. Locking, the most common concurrency option, presents risks for inexperienced programmers, such as the famous Deadlock and Livelock problems. As we move from single core architectures to multicore, our programming languages need to make it easier for the programmers to use concurrency. Many researchers have pointed at Software Transactional Memory (STM) as an answer to that issue, as it is a lock-free, abstract way to guarantee isolated access to shared resources. But adapting for STM a program that uses lock is not simple. Besides being an error-prone task, technical details of the language might require special attention to preserve the program’s behavior. In this dissertation, we propose a set of program transformations for concurrency constructs in Haskell, a purely functional programming language. They may be used to refactor a program’s existing locks into transactional constructs from Haskell’s STM implementation. This allows a programmer to gain the benefits of working on STM even for programs which were already developed using locks. Each transformation is accompanied by execution examples and a discussion on its ability to preserve program behavior. We also present a supporting study, in which a controlled experiment was used to evaluate the benefits of locks or STM for the development of Haskell programs. Although subjects’ opinions tended to favor lock-based concurrency, those which used STM overall committed significantly fewer mistakes and required on average 12% less time to finish their assignments. / Recentemente, a queda na taxa de crescimento da quantidade de transístores integráveis em processadores tem desacelerado o crescimento de poder computacional. A lei de Moore parece aproximar-se de seu fim. Com isso, é desafiada a premissa de que software escrito hoje terá melhor desempenho no futuro simplesmente devido à evolução dos processadores. Ainda assim, aplicações paralelas ainda podem se tornar mais eficientes ao se distribuir trabalho entre diferentes processadores para execução simultânea. Para permitir a paralelização, são necessários múltiplos núcleos de processamento, o que tem levado à popularização de arquiteturas multinúcleo. Entretanto, a escrita de aplicações paralelas não é trivial. Deve-se escrever um programa para execução paralela desde sua concepção, ou adaptá-lo posteriormente para execução paralela. O programador tem a difícil tarefa de paralelização da aplicação através do uso de construções de concorrência e paralelismo. Travas, a mais comum opção para concorrência, apresentam riscos para programadores inexperientes, tais quais os famosos problemas de Deadlock e Livelock. Ao adaptarem-se de arquiteturas de um único núcleo para as de multinúcleo, as linguagens de programação precisam facilitar o uso de concorrência para os programadores. Muitos pesquisadores têm indicado Memória Transacional em Software (STM, do inglês Software Transactional Memory) como a resposta para esse problema, por ser uma forma abstrata e não bloqueante para garantia de acesso isolado a recursos compartilhados. Mas adaptar para STM programas que usam travas não é simples. Além de ser uma atividade propensa a erros, detalhes técnicos da linguagem podem requerer cuidados para se preservar o comportamento do programa. Nesta dissertação, é proposto um conjunto de transformações de programas para construções de concorrência em Haskell, uma linguagem de programação puramente funcional. Elas podem ser usadas para refatorar travas de um programa para uso de construções transacionais da implementação de STM em Haskell. Isso permite ao programador aproveitar os benefícios do trabalho com STM mesmo para programas já desenvolvidos com uso de travas. Cada transformação é acompanhada de exemplos de execução e uma discussão sobre sua capacidade de preservar o comportamento do programa. Também é apresentado um estudo de apoio, no qual um experimento controlado foi usado para avaliar os benefícios do uso de travas ou STM no desenvolvimento de programas em Haskell. Apesar das opiniões dos participantes terem favorecido o uso de travas, aqueles que usaram STM cometeram em geral menos erros e em média precisaram de 12% a menos de tempo para terminar suas tarefas.

Morfologické změny obličeje dospělých mužů a žen během stárnutí / Morphological changes of adult human face during aging

Čiháková, Lucie January 2016 (has links)
Processes of biological changes of organism over time distinctly manifest themselves in a face morphology. The present study age changes are observed as shape and size changes of transversal dates of surface 3D virtual models of faces of 443 women and men (22-88 years old) devided into six age groups in decade. Differences in faces among each age group with respect to the sex were investigated and a sexual dimorphism and its gradual progress with the age using methods of geometric morphometrics (coherent point drift - dense correspondence algorithm, principal component analysis, per vertex t-test, shell-to-shell deviation). A significant difference among age categories was observedd both in shape as well as in form of the face. The faces of women and men were becoming wider with age and convexity was decreasing at the same time. A decline of the whole forehead and of the profile of the men's nose was observed, whereas the women's foreheadwas getting bevel due to the decline of the top part and a profile of the nose wasn't changed with the age. On contrary, the men's chin was unvarying with the age, while the women's chin was sliding out foward. There was observed a distinct decline in the front part of a upper jaw with the both sex. It was found out that after the seventh life decade the face gets...

Faktory ovlivňující rychlost produkce ohýbaného tvaru slova u dětí ve věku do 15 let / Factors affecting speeded production of inflected word forms by children under age of 15

Salzmannová, Lucie January 2021 (has links)
The thesis focuses on the processing of morphologically complex words in Czech. It follows up on the previous research in the field of inflectional morphology, in which Czech is minimally represented. The thesis is divided into two parts. The first part describes the main theoretical approaches, which are connectionism and dualism. The second part describes an experiment, which was carried out following the previous research and aimed at comparing the claims of the two main approaches. The experiment was conducted on 37 native speakers of Czech aged from eight to eleven. The participants' task was to say as quickly as possible the genitive form of a noun that appeared on the screen of an electronic device in nominative form. The results of the research do not support the dualistic thoughts, but rather support the connectionist view. However, further empirical research is needed for a clear conclusion. Key words speeded production; inflected word form; frequency; language acquisition; inflection

Modelování vysokofrekvenčních pulsací / High-Frequency Pulsations Modeling

Střecha, Ludvík January 2008 (has links)
The diploma thesis deals with the mathematical modeling of high-frequency pressure pulsations in water turbines. Pulsations are caused by the interaction between stator a rotor blades. These high-frequency pressure pulsations then cause high cycle fatigue of the head cover, spiral casing, runner and distributor. The mathematical model is solved by transfer matrix method. Data are processed in F-A char and MS Excel programs. Final results are demonstrated by frequency amplitude characteristics and by pressure mode shapes, where comparison of the mathematical model with the measurement is shown.
