Force ductility of asphalt binders
Smolka, Zdeněk ; Coufalík, Pavel (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis describes a laboratory characteristics of bituminous binders. There will be described the principle and results of laboratory tests, needle penetration, softening point by ring and ball and force ductility. The tests will be performed on samples of the bituminous binders with different degrees of modification.

Study of the adheisve affinity into the wood cell wall at the sub-microstructural level
Mitrenga, Ondřej ; Rovnaník, Pavel (referee) ; Vaněrek, Jan (advisor)
This thesis focuses on the problematic of adhesive affinity into wood cell wall at the sub-microstructural level. The main subject of this thesis is research work of scholarly articles focused on the penetration of resins and polymers into the cell wall of the wood. In contains a description of the principles on which the used methods are based, and a summary of the results achieved. In the experiment, several method were used to investigate the possible penetration of selected methods adhesives into the structure of the cell wall. These are fluorescence microscopy, confocal microscopy, scannin electron microscopy (SEM) and transmission electron microscopy (TEM).

Stone mastic asphalts with recycled materials - bituminous binders properties
Dzurková, Veronika ; Coufalíková, Iva (referee) ; Hýzl, Petr (advisor)
The bachelor thesis is focused on the issue of adding R-material to stone mastic asphalt mixtures (SMA). The material was obtained from a plant that put the mixture in the test section on the road II/227. The theoretical part describes the problems of recycling of asphalt roads, bituminal binder theory and problems associated with the addition of R-material to hot asphalt mixtures. Bituminal binders from mixtures with different percentages of R-material were extracted in the practical part. Empirical and functional tests were performed on these binders. The aim of the thesis is to determine the influence of the presence of R-material on SMA asphalt mixture in terms of properties of asphalt binder.

Study of the interphase region of wood bonds
Chlup, David ; Dufka, Amos (referee) ; Vaněrek, Jan (advisor)
This bachelor thesis deals with summarizing knowledge on issues related to the penetration depth of the adhesive into the wood structure. In the thesis they are described all adhesion theories. We focus on the effect of viscosity and durability bond line according to varying amounts of filler adhesive. Furthermore, it is described some microscopic techniques, which measure the penetration of the adhesive into the cell structure.

Resistance of bituminous binder to ageing
Rous, Vojtěch ; Frýbort, David (referee) ; Kudrna, Jan (advisor)
Asphalt binder ageing and experiences with various ageing methods from abroad are described in this thesis. The practical part deals with the RTFOT aging and with the influence of the duration of this test. The comparison of test results is conducted before and after the aging by values of needle penetration, elastic recovery, softening point and resilience tests are evaluated and compared.

Design of asphalt mixtures with the use of higher amount of RAP
Pavličík, Petr ; Matoušek, David (referee) ; Varaus, Michal (advisor)
In the introduction of the Master’s thesis describes for obtaining and processing of reclaimed asphlalt. Major point of the thesis is design of asphalt mixtures with use of higher amount of RAP for asphalt binder course. Asphalt mixtures were designed with contents of 0%, 30%, 50% and 70% of RAP. On each asphalt mixtures were compared parameters set out by functional tests – resistence to permanent deformation and resistence to water.

Modules for Manual Penetration Testing of a Web Application
Heriban, Radoslav ; Martinásek, Zdeněk (referee) ; Šeda, Pavel (advisor)
The main goal of this master's thesis was development of Burp Suite extension capable of interacting with various other automated tools, accompanied with development of a web application. Chapter two contains analysis of tools commonly used in penetration testing that could benefit from the ability to share Burp Suites data or functionality. The programming languages used were Java and JavaScript. The extension acts as a gateway to inner functionality of Burp Suite. It enables exfiltration of in memory objects such as sitemap, proxy history or found issues in JSON format to other tools, and also listens for incoming data that can be inserted into it's existing modules such as Repeater, Scanner, Spider or Comparer. Frontend application was written using JavaScript library React. The web application offers a graphical visualization of issue data.

In Space
Blatná, Hana ; Vítková, Lenka (referee) ; Klímová, Barbora (advisor)
The bachelor's thesis is a series of fourteen drawings created exclusively using graphite. The drawings reflect a subjective view of the universe, inspired by archaic interpretations of planets and universe solids, conspiracy theories, black and white images of textures, surfaces, rocks and meteorites captured by modern technology. The drawings are an attempt to express hidden inner motives, personal mythology, the energy of the landscape, the relationship to nature. The paper is a parallel to the sky, a projection surface on which dreamy cosmic landscapes penetrate in imprints, geometric shapes and using perspective.

Optimized manufacturing of aluminium castings by using lost wax technology
Talanda, Ivan ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
Aim of this diploma thesis is to choose new pattern wax for Fimes a.s. foundry. New wax should substitute old not fully satisfactory pattern wax which caused problems in technological process resulting in increased number of rejects. New pattern wax should eliminate current problems and help foundry with producing large, thin-walled, high-quality castings. Numbers of pattern waxes supplied by world’s leading wax manufacturers were subjected to laboratory tests and pilot study. This diploma thesis is part of project Alfa TA01010766: „Research and development of production technology large, thin and high quality castings of aluminium alloys “
