Design sedacího prvku z pěny

Dudová, Klára January 2017 (has links)
This thesis deals with the design of a foam sitting element. In order to create a successful design, it was necessary to study the theory and then proceed to the design process proper. The first part of the thesis analyses the history and typology of upholstered seating furniture, ergonomics, anthropometry and proper dimensions. A considerable part is dedicated to polyurethane foams and their processing. The second part of this thesis describes the product designing process, from research and first ideas through sketches, models creation, design modifications to prototyping at 1:1 scale.

Vývoj a výzkum prvků keramických zdících systémů pro oblasti se zvýšeným rizikem záplav / Development and research of elements of ceramic masonry systems for areas with increased risk of floods

Novák, Vítězslav Unknown Date (has links)
One of the most widespread causes of building deterioration is high moisture, which in extreme cases may even arrive as floods. The action of high moisture in a structure often results in damage or alteration of properties, but it can be mitigated with various protective measures, most commonly waterproofing. However, the efficacy of waterproofing depends of flawless implementation. Another effective form of protection against high moisture is the correct choice of location, but the number of suitable construction plots is rapidly decreasing or their price is too high. This is why new construction, particularly family homes, now occurs even in locations known for the increased risk of high moisture. This doctoral thesis focuses on the research and development of the most common masonry systems with structural clay tiles designed to withstand application in flood areas thanks to the special properties of the individual elements, components, and the system as a whole.

Sexualita jako dějotvorný prvek v současných televizních seriálech / Sexuality as a storylinig element in the present television soap operas

Dolejší, Tereza January 2014 (has links)
A diploma thesis deals with sexuality as a storylining element in Czech soap operas. The sample contains long-running relational series that were broadcasted by television stations in October-November 2013. Specifically, there were series Cesty domů 2, Gympl s (r)učením omezeným, Ulice and Ordinace v růžové zahradě 2. There were used quantitative content analysis to detection the frequency of sexuality and qualitative narrative analysis to explore the context and way for create the plot. The categories of behavior and conversation containing elements of sexuality were analyzed in the study. During the preparation of the categories, I was inspired by research "How much sex is there in soap operas on British TV?" that was realized by Rami Al - Sayed and Barrie Gunter in 2012. I analyzed the elements of sexuality that create the storyline during the research. I examined the particular scenes where did appear the correlation of story to the previous and following events and debates . I focused on the explicit and implicit exposure of sexuality in the series. If there was an aspect of sexuality without storylining function I tried to find the reason for the occurrence in the series. The theoretical establishment of the topic deals with issues of narrative and discourse of sexuality. There are presented...

Distribuce stopových prvků v karbonatitech pomocí in-situ metod, se zvláštním zřetelem k REE / Distribution of trace elements in carbonatites using in-situ techniques, with focus on REE

Krátký, Ondřej January 2017 (has links)
Carbonatites are unique and enigmatic magmatic rocks of unclear origin, with very specific mineralogy and geochemical properties. They are predominantly composed of magmatic calcite or other carbonate minerals (Le Bas 1987) and have low content of SiO2 (Le Maitre 2002). Origin of these peculiar magmas is still not clear but they appear to represent an important "window" into processes in Earth's mantle. They are considered either as residual melts from a fractionated carbonated nephelinite or melilitite (Gittins 1989; Gittins and Jago 1998), as immiscible fractions of CO2-saturated silicate melts (Freestone and Hamilton 1980; Amundsen 1987; Kjarsgaard and Hamilton 1988, 1989; Brooker and Hamilton 1990; Kjarsgaard and Peterson 1991; Church and Jones 1995; Lee and Wyllie 1997; Dawson 1998; Halama et al. 2005; Brooker and Kjarsgaard 2011), or as primary melts which are were generated from CO2-bearing peridotite through partial melting (Wallace and Green 1988; Sweeney 1994; Harmer and Gittins 1998; Harmer et al. 1998; Ying et al. 2004). Abundances of rare earth elements (REE) are often high in carbonatites because carbonatitic magmas can dissolve these elements much easily than silicate magmas (Nelson et al. 1988). Carbonatitic magma can also dissolve large quantities of Sr, Ba, P and mainly Zr and Nb,...

Dynamická elektroneurostimulace a elektrické vlastnosti kůže / Dynamic electroneurostimulation and electrical properties of skin

Špeta, Marek January 2013 (has links)
The focus of this diploma thesis is on theoretical basics of dynamic electroneurostimulation, which is an effect of electrical signal on acupuncture points of skin. This technology is used in devices made by russian DiaDENS company. Practical part of this thesis covers design of human skin impedance model. Especially derivation from three-element Cole-Cole model. Elementary, there is design of equivalent circuit of constant phase element and its incorporation into circuit. Then this circuit is designed, simulated and produced. Resulting product is used as a load to measure the characteristics of the DiaDENS device.

Speciální difraktivní prvky - využití fraktálů / Special diffractive element based on fractals

Kala, Miroslav January 2009 (has links)
This diploma project is focused on use the fractals in diffractive optical elements. Properties of diffraction patterns of various fractals are investigated. Properties of some simpler non-fractal structures are investigated too. Diffraction patterns are created by computer with program written in Delphi programming language. Potentialities of use the fractals in security optical elements (holograms) and their advantages against the classic non-fractal structures.

Porovnání implementace GUI v různých knihovnách v OS Linux / Comparing GUI Implementation in Different Libraries in OS Linux

Šelepa, Jan January 2009 (has links)
This thesis presents the elemental properties and principles in graphical user interface. It then shows how one can work with a graphical user interface on GNU/Linux operating system and gives some examples of toolkits used for this purpose. The next part shows the design of an aplication based on an existing anti-virus program. The last part shows the dierences between the two implementations of the designed application.

Patala, Petr January 2012 (has links)
The objective of this master’s thesis is monitoring and management of computer networks via SNMP protocol and its practical application. The main part describes working with SNMPc program in an experimental network through implementation of its parts into the network and configuration of SNMP agents on routers, switch and end station. This thesis includes the results of traffic testing, disconnected links, effects of traffic load on QoS parameters, making longterm statistics, baselines and alarms. The thesis also includes parametres obtained with SNMP protocol from network nodes and end station.

Pologrupy mřížových bodů / Semigroups of lattice points

Scholle, Marek January 2012 (has links)
The thesis deals with subsemigroups of (Nm 0 , +), a special discussion is later devoted to the cases m = 1, m = 2 and m = 3. We prove that a subsemigroup of Nm 0 is finitely generated if and only if its generated cone is finitely generated (equivalently polyhedral) and we describe basic topological properties of such cones. We give a few examples illustrating that conditions sufficient for finite generation in N2 0 can not be easily trans- ferred to higher dimensions. We define the Hilbert basis and the related notion of Carathéodory's rank. Besides their basic properties we prove that Carathédory's rank of a subsemigroup of Nm 0 , m = 1, 2, 3, is less than or equal to m. A particular attention is devoted to the subsemigroups containing non-trivial subsemigroups of "subtractive" elements.
