Cyanoacrylate adhesives in industry
Novák, Libor ; Halamík, Tomáš (referee) ; Kubíček, Jaroslav (advisor)
The diploma thesis is processed as an experimental verification of properties of cyanoacrylate adhesives Loctite and SikaLock. The experiment compares properties of mentioned adhesives on ten different materials. These Materials were glued to the overlap joint. After bonding one part of samples were left usual conditions and the second part was put into the kataplasma, where the samples were exposed extreme conditions (high wetness and temperature). The next step was a test for shear stress. Measured values were recorded in graphs, for each pasted material.

Machinery used in an open die forging
Novák, Libor ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
For production of components, which are made by open die forging, are used forging hammers and hydraulic presses. The project contains a dividing of machines, short description, advantages and disadvantages and using of concrete types of forging hammers and hydraulic presses in practice. Advantages of forging hammers are simple construction, high range of choice from many types and simple maintenance. Disadvantages are big shakes and danger of accident. Forging hammers can be chosen from spring, pneumatic, hydraulic and steam air types with or without acceleration. Hydraulic presses are divided into push -down presses (two and four - column presses) and pull - down presses (two and four - column presses). Advantages consist in simple operating and controlling via computer. Disadvantages are complicated construction and difficult maintenance.

Evaluation of landscape permeability and migration potential - A Case Study on the motorway D10
Novák, Libor ; Keken, Zdeněk (advisor) ; Kušta, Tomáš (referee)
This thesis deals with the influence of technical barriers to accidents with wild animals. On the highway D10 during the years 2006-2014 a total of 598 accidents with animals happened. Six categories of barriers were determine: 1) no barrier, 2) metal guardrails, 3) concrete dividers, 4) reinforced metal guardrails, 5) noise barrier wall, 6) fence, which had been given spatial location during the field survey. The paper also addressed the impact of urbanized areas and created the density of accidents per 1 km of the highway. The results show that there was no evidence for an effect of technical barriers (p = 0.73164). An analysis of accidents density implies some hotspots where there is > 19 accidents / km.
