Analýza CNC spojů využívaných v nábytkářském průmysluGajdoš, Martin January 2015 (has links)
CNC joints represent a non-traditional way of connecting materials. The work focuses on an analysis of the connections in the view of selected historical context, the philosophy and the real situation, as well as new production lines based on this relatively new technology. Additionally, other characteristics of CNC connection, such as aestheics properties or effects of multiple joints coexistence in a product, are described in practical part. These documents are followed by a questionnaire for producers of furniture which explores their attitude to these joints. The questionnaire should help to clarify the ability of the joint to compete on the market; and the willingness of manufacturers to implement the philosophy of CNC joinery into its production. The author produced a sample consisting of four typical CNC connections, milled on a CNC machining center as an outcome of all the collected knowledge. The production of the sample will help to determine material, economic and also skill demands of product manufacturing which are based on this connection. The work contains a thematic literature review, an analysis of selected properties of the connection, a questionnaire, its evaluation, results interpretation, and description of the CNC joints sample production. The last part summarizing the results and CNC joint potential in relation to the furniture.

Analýza svarových spojů korozivzdorné oceli s běžnou uhlíkovou ocelíHartman, Tomáš January 2016 (has links)
Diploma thesis is focused on analysis of welded joints of ordinary carbon steel with corrosion-resistant, made by commercially available methods TIG, WIG, MMA and spot welding. Thesis describes welding methods used in heavy and light industry in detail. Next section describes creation of homogeneous welds based A-F, suitable methods and problems with these welding seams. Experimental part deals with creating a transition weld joints between 1.0330 and 1.4301 materials and comparing of their quality. Welds are subjected to the effects of salt fog and then degradation of the transition zone was observed caused by corrosion. Subsequently, the welds are subjected to metallographic examination, a tensile test, and the resulted weld metal is analyzed in Schaeffler diagram.

Veřejné zakázky na homogenní statky: empirická studie z České republiky / Public Procurement of homogeneous goods: Czech Republic case studySoudek, Jan January 2012 (has links)
The goal of this thesis is to show that institutional and procedural characteristics are affecting the final price of the public procurement. In order to be able to compare the tenders among each other, only public procurement of homogeneous goods is analyzed. The presented model attempts to explain a variation in final price per one unit as a function of estimated unit price, market price and characteristic of procurement procedure - type of procedure, number of bidders and use of electronic auction. In case of electricity and gas public procurement final price elasticity with respect to the estimated price tents to be higher than such elasticity with respect to the market price. This result suggests high rigidity in public procurement procedures. We show that such ineffectiveness is reduced by using open procedure, electronic auction or attracting more bidders.

Studie návrhu malých vodních nádrží v k.ú. Držková, na lokalitě I.Ottová, Gabriela January 2017 (has links)
My thesis handles the study of small reservoir on the selected area in the village Držková. Small water reservoirs have controlled side tributary, the dam is homogeneous discharge device, gullet, reservoir does not have a spillway. A small pond is part of the design of more elements. This newly created interactive element will act as the landscape, increase biodiversity and ultimately will serve to retain water in the landscape. The resulting proposal was preceded by geodetic survey, field survey locations, meeting with the client and geological survey. Planting of woody vegetation is a part of the water reservoirs construction work.

Rovinné mechanismy / Planar mechanismsHOFFMAN, Jan January 2013 (has links)
This work thesis is dealing with planar mechanisms. It?s concentrated on definition the topic, enumeration methods of mathematical description of mechanisms and occasion of simulation with usage information technology. It?s going mainly on GeoGebra program, in which were created most of schemes and models mechanisms. Created models are recorded on attached CD. Important charter of this theses are mechanisms used to draving planar curves, ending with mechanisms used to drawing straight line.

Vývoj souborného katalogu ČR, základní problémové okruhy a varianty jejich řešení / The development of a Union Catalogue of the Czech Republic, the basic sets of problems and some variants of their solutionLodrová, Iveta January 2014 (has links)
This diploma thesis provides information about the Union Catalogue of the Czech Republic (SK ČR) and its new tasks related to Conception of development of libraries during the years 2011-2015. The aim is to show basic sets of problems, their analysis and some variants of their solutions, compared to other foreign union catalogues. The first and second part of the thesis deals with foreign union catalogues - British example of heterogeneous environment Copac: National, Academic and Specialist Catalogue, and Slovak example of homogeneous environment KIS3G, their analysis and development from the beginning to the present, current status and future plans. The third part describes SK ČR, including semi-structured interview with head of the Union Catalogues Department of the National Library, PhDr. Eva Svobodová and findings from SK ČR workgroup meeting. The final part presents the summary and comparison of the three union catalogues.

Metrické prostory se vzdálenostmi z pologrupy / Semigroup-valued metric spacesKonečný, Matěj January 2019 (has links)
The structural Ramsey theory is a field on the boundary of combinatorics and model theory with deep connections to topological dynamics. Most of the known Ramsey classes in finite binary symmetric relational language can be shown to be Ramsey by utilizing a variant of the shortest path completion (e.g. Sauer's S-metric spaces, Conant's generalised metric spaces, Braunfeld's Λ-ultrametric spaces or Cherlin's metrically homogeneous graphs). In this thesis we explore the limits of the shortest path completion. We offer a unifying framework - semigroup-valued metric spaces - for all the aforementioned Ramsey classes and study their Ramsey expansions and EPPA (the extension property for partial automorphisms). Our results can be seen as evidence for the importance of studying the completion problem for amalgamation classes and have some further applications (such as the stationary independence relation). As a corollary of our general theorems, we reprove results of Hubička and Nešetřil on Sauer's S-metric spaces, results of Hubička, Nešetřil and the author on Conant's generalised metric spaces, Braunfeld's results on Λ-ultrametric spaces and the results of Aranda et al. on Cherlin's primitive 3-constrained metrically homogeneous graphs. We also solve several open problems such as EPPA for Λ-ultrametric...

Role ekologických faktorů při udržování sexuality / The role of ecological factors in maintenance of sexualityToman, Jan January 2013 (has links)
The existence and widespread distribution of sexual reproduction despite its obvious disadvantages is an evolutionary enigma. According to the theory of frozen plasticity, the evolution of sexual and asexual species is fundamentally different. One of the implications of this theory are different ecological preferences of these species. Sexual species should prefer biotically and abiotically variable environments because of their ability to quickly and reversibly respond to unpredictable changes. On the other hand, asexual species should prosper in biotically and abiotically stable environments because of their ability to perfectly adapt even to extreme environmental factors in the long term. I decided to test these predictions in the metastudy comparing ancient asexual clades (in which we can be sure about their obligate asexuality and evolutionary longevity) with their sexual sister or closely related ecologically comparable clades. The hypothesis of the preference of asexual species to biotically and abiotically homogenous environments was supported by the results of this metastudy. On the other hand, the hypothesis of supposed ability of asexual species to perfectly adapt to a broader range of environmental conditions, tested on the comparison of temperature ranges of activity of previously...
