Wireless Communication in Home Automation
Prokop, Michal ; Gutman, Jiří (referee) ; Hynčica, Ondřej (advisor)
This bachelor thesis is about how to make wireless communication network by IQRF technology which is intended for a home automation. It’s created by using DPA custom handler. This network can be made without programming thanks to DPA custom handler. This wireless network is realized by light model that is controlled by coordinator or by a button on a node. After that I measured latency and energy consumption on several various synchronous network and asynchronous network.

Bonding of thin metal sheets
Poul, David ; Kubíček, Jaroslav (referee) ; Dvořák, Milan (advisor)
Bachelor thesis is focused on theory and methods of adhesive bonding. Experimental part is focused on two topics: determining dependences of bonded joint shear tension on a cure time and determining dependences of bonded joint shear tension on a size of contact area. Loctite SI 5399 RD acetoxy silicone one component glue was used for these experiments. At determining dependences of bonded joint shear tension on a size of contact area tension is raising, but the grow wasn’t directly proportional on the grow of size of contact area. Determining dependences of bonded join shear tension on a cure time it was proved, that tension is raising first 24 hours very quickly. After this period is process slowing down and tension is increasing to its maximum. After 18 hours bond tension is solid enough to be handling, but 24 hours of curing time is more secured.

Manufacturing technology of rail vehicle by new adhesive systems
Tesař, Petr ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
This master´s thesis deals with the bonding process, which is the dominant technology of the production of door leaves for railway vehicles. Following the necessary study of the basic essence of bonded joints the thesis further introduces the individual construction options of this product. The essential part of the thesis is represented by presentation of the achieved results of the testing of individual selected types of adhesives. On the basis of these results the most suitable type and supplier of industrial adhesive is selected.

Bonding of composite materials
Drkoš, Jan ; Molliková, Eva (referee) ; Němec, Karel (advisor)
The thesis deals with the analysis of the bonding of composite materials and the subsequent selection of adhesive for the specified glued joint consisting of two pieces of carbon composites. The thesis summarizes the theory of composite materials and then explains in more detail the theory of bonding together with the subsequent testing of glued joint. Another part of the thesis focuses on the market research in the field of available and suitable adhesives and the subsequent selection of the new adhesive for the glued joint, on which the epoxy adhesive was previously used. In this part, glued joints with two pre-selected adhesives were tested and then a conclusion was drawn for the selection of the most suitable adhesive.

Precise bonding of composite materials
Tellinger, Adam ; Gregor, Lukáš (referee) ; Kupčák, Radim (advisor)
This bachelor's thesis deals with the issue of bonding composite materials. The first part of the bachelor's thesis is focused on research into the production of composite materials and gluing technologies. The content of the practical part is the design of test specimens and a preparation for their bonding with subsequent production. Furthermore, verification of compliance with the required accuracy of bonded joints when using different adhesives using 3D measurements.

Rationalization of the production line
Straka, Jiří ; Štipčák, Jaroslav (referee) ; Osička, Karel (advisor)
This masters thesis optimises production of the step plates (which are parts of the sliding steps systems used in tramways, subways, hi-speed trains etc.) to increase the production rate to meet customers demand. The purpose of the work was reached by detailed analysis of the production process followed by evaluation of the results which led to the list of the possible solutions. The solution with the greatest time improvement was chosen and explained in detail.

Bridge crossing over Svitava river and railway track in Blansko
Smělíková, Petra ; Konečný, Vojtěch (referee) ; Křižan, Lukáš (advisor)
The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.

Testing bonded steel sheet coated with zinc
Zedníček, Zbyněk ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The aim of this master´s thesis is the design chosen for testing bonded joints on the specified galvanized steel sheet in laboratory conditions and obtaining parameters of bonded joints for application in industrial practice. Basic tests for testing bounded joints were presented in the work. Subsequently, two tests were selected and verified in laboratory conditions. The result of these tests are specific numerical values that were compared with values gained during tests linking method clinch.

Sheets bonding and their testing
Straka, Jan ; Kandus, Bohumil (referee) ; Dvořák, Milan (advisor)
The aim of this bachelor thesis is to design selected load tests for bonded joints at specified steel sheet DC01 under laboratory conditions and to compare the strength of the degreased joints with technical alcohol and uncrushed joints. The basic methods of joining thin sheets are presented in the thesis. The following is an overview of test methods for bonded sheets according to the relevant technical standards. The results of the selected tests are the specific numerical values that have been compared with those reported by the manufacturer of the particular adhesive.

Adhezive bonding in the car industry
Bláha, Aleš ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis examines bonded joints of car bodies, which are the most mechanically challenged for selection of suitable, modern adhesives for the construction of the car body. The first part focuses on the description of the bonding technology, including theoretical knowledge related to the use for bonding assemblies for bodywork. The specified structure and its solution is carried out in the way that were selected by three types of adhesives SIKA and mutual comparison of their properties. After that an experimental test is conducted at 18 samples per overhanging shear tensile strength and finally followed by the evaluation and selection of the most appropriate and optimal variant for various bonding applications.
