Dizertační práce zpracovává historický vývoj konstrukce a použitých materiálů úložného nábytku od 17. až po začátek 20. století a jej propojení (aplikaci) na současnou nábytkovou tvorbu. Zaměřuje se na rozbor vlastností spojů používaných ve výrobě nábytku. Na vybraných typech spojů nábytku budou vykonané experimentální testy, kde se bude zkoumat vliv rozměrů jednotlivých částí konstrukčních elementů vybraného typu spoje a druhu dřeviny na pevnost nábytkových spojů. Rovněž se bude zkoumat vliv typu použitého lepidla. Vybrané druhy lepidel budou určeny na nábytkové konstrukce. Jednotlivé pevnosti vybraných nábytkových spojů budou analyzovány s výpočtovým modelem pomoci metody konečných prvků. Pomocí počítačové simulace se budou jednotlivé typy nábytkových spojů porovnávat, s cílem najít nebezpečné koncentrace napětí. Tyto údaje poskytnou pro konstruktéry informace, kde je nutné daný materiál zesílit, případně zvětšit geometrické parametry konstrukčních elementů. Předpokládaným výstupem předkládaného projektu je návrh nových geometrických parametrů konstrukčních elementů a korekce dlouhodobě zažitých nedostatků uplatňovaných při tvorbě spojů.

This diploma thesis deals with bonded hybrid joints which are used for connecting parts of modern coachwork. Firstly, the thesis describes in general the process of production of the whole coachwork, from cutting of the blanks to the surface treatment including the analysis of the used materials. Subsequently, the problem of joining body parts through adhesives, but also by welding, soldering or other methods is discussed. Another part of this thesis is dedicated to an experiment in which the qualities of bonded hybrid joints were determined. Different ways of realizing the joint have been made which differed in the size of the glued surface, in the welding methods and in the process of their creation. The produced joints were tested for their strength and quality.

The thesis deals with problems concerning lead free soldering especially the study of the structure of solder joints and their reliability. The thesis evaluates lead free solder alloys. The theoretical part includes basic principles of soldering and methods of investigating solder joints reliability. The experimental part deals with the impact of water cooling and vibration on solder joint structure. Both methods are tested and are evaluated with regard to their reliability. The used tests include X-ray inspection, optical inspection, mechanical tests, investigating joint structure with electrone microscope.

The submitted work deals with issues of optical transmissions and its security. We will become familiar with a variety of transferability of information, based on which we can assess the advantages and disadvantages of each technology as compared to optical information transmission. Based on acquired information we will try to implement interception of optical communication of cable TV provider.

The Master's thesis deals with the determination of measurement method of deflection the axis of the optical beam from its ideal position, which is caused by action of force of strong winds affecting the positional stability of the building or supporting structure (tower) used for placement of FSO links'heads. The thesis informs the readers about the other causes of deflection of beam axis in a real environment, about methods of determining the position of the beam axis in the plane perpendicular to the beam axis and the basic properties and parameters of the Gauss beams, including the phenomenon of diffraction on the output aperture of the laser transmitter.

The subject of my thesis is a static analysis of a different trusses of a great span length. The preface is devoted to the trusses their creation of plane models of a girder with the extent of 18 metres. The questions of construction´s joints are mainly solid. The conclusion is dedicated to the creation of the girder and joints´ formation.

This dissertation deals with the problematic of the free space optical link availability determination. For the presumption of the free space optical link unavailability we have to know statistical distribution of the atmospheric attenuations. In this work is also presented the measurement of these atmospheric attenuations with the specially designed optical link. Measurement is using switching of the two separate transmitters with wavelengths of 830 nm and 1550 nm. Presented statistic distribution let us determine the suitability of the link in the chosen locality during its design. Comparison of our measurement with other models like model based on the meteorological visibility is also presented. The last part of this work is focused on the preconditions for the hi-speed network bit error rate determination. Sample of the bit error rate measurement obtained by our designed bit error rate tester is attached.

This diploma thesis solves the problem of a suitable combination of used adhesive and the shape of a glued joint, to produce a battenboard usable in the production of kitchen products washable in dishwasher. The tested samples were made of beech and oak and their edges were machined into glued joints of the wedge calk, the blunt joint and the double wedge pen. For testing were used two polyvinyl acetate adhesives and one polyurethane adhesive with different types of moisture resistance. The resistance of the samples to bending stresses on the glued joint was tested before exposure to the washing process and after the completion of thirty washing cycles. The theoretical part includes a literary overview and methodology dealing with the given issue, the practical part describes the achieved results.

The main object of this theses is make research of issues relating to joints and CNC technology, find out information and apply this in design and manufacture of CNC tenon joint. The thesis contains definition of basic concepts, resource searching, background research, historical contexts introduction a basic information to exist theme. Teoretic part contains subjects relevant to joints in general, conventional joints, CNC joints, NC and CNC machine tools, CAD and CAM systems and NC programmes making. A part of the thesis is design of CNC tenon joint and its application on particular product. To design relates selection and application of proper materials, design documentation, 3D models and visualization exist product. The principal result of this theses should be manufactured prototype of designed product. In conclusion there are results review, incurred difficulties and its solutions.

The thesis describes the design of complex of identical four timber houses disposed over a particular area. The thesis also contains documentation for the implementation. Objects will be used for recreational accommodation purpose on an organic farm. One building is designed for a capacity of at least 6 people. Project is focused on one type object for which are developed construction drawings needed for construction permit check. The thesis is mainly focused on manufacturing documentation and output from modelling software for timber constructions made by DIETRICHS company. For the needs of an investor, for possible design of composition of timber construction were proposed, for which were performed calculations of coefficient of heat transfer and calculations of the house constructions project documents. Due to chosen construction technology, the first part of the thesis is focused on basic information related to timber constructions from the perspective of history. Description of possibilities of corner joints are also included in thesis.
