Influence of Inert Atmosphere on Surface Wetting in Lead Free Soldering
Nestrojil, Michal ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
This master´s thesis dealing with study of influence of inert atmosphere on the wettability of soldered surfaces. The theoretical part is discussed the issue of the soldering, solder joint, oxidation, and inert atmosphere. The glass cover with internal inert gas preheating for the wetting balance testing was prepared in the practical part. With this adjustment were realised tests, in which was examined the effect of the inert gases on the wettability of different materials combination. Further experiments were focused on plasma surface cleaning as possible flux substitution. The evaluation of these experiments were discussed in the end of this master´s thesis. Some of topics were designed for further experiments.

Wine factory
Nestrojil, Michal ; Blažková, Vendula (referee) ; Daněk, Lukáš (advisor)
The aim of the Master thesis is to design a new building of winery in Drnholec in Výsluní street located on plot No. 1643/81. It is a sloping plot with total area 18 158 m2. The building has two above-ground floors and a basement. In the basement there is a vertical load-bearing structure consists of cast-in-place reinforced conrete and in the above-ground floor there are sand-lime blocks. A horizontal load-bearing structure are design from prestressed panel Spiroll. There is designed a green warm flat roof. This complex of winery is divided into four independently functional operation: wine production, administrative part, accommodation and tasting room with retail. In the basement there is situated wine production with technical facilities. In the ground floor there is a separate area with tasting room and its support area, further there is a part of wine production, retail, office and staff facilities. In the first floor there is accommodation. The design of the building emphasizes the architectural character and the building also meets the energy requirements in full. The shape solution is designed so that the object fits into the vineyard environment.

Family house with an establishment
Nestrojil, Michal ; Hnízdilová, Aneta Aya (referee) ; Daněk, Lukáš (advisor)
This thesis deals with design and development of a project work for the construction of a family house with facility (the Wine bar) in Brtnice. The object is situated on the parcel number 1744/108, cadastral area of Brtnice. The project respects the municipal plan. The object is partially with a basement and has one ground floor with a wall construction system made of HELUZ brick blocks, it is based on based on concrete footings and covered with a flat roof. Part of the building is a garage for one car. The main entrances to the building are at the level of the first floor and they are located on the eastern side. The house is designed as a one housing unit for permanent residence of a five-member family. The project was processed using the AutoCAD software. During the processing the emphasis was put on the right layout solution, architectural design, static requirements and safe use of the building.

Lead Free Solder Joint - Models for Reliability Prediction
Nestrojil, Michal ; Šandera, Josef (referee) ; Starý, Jiří (advisor)
This bachelor's thesis deals with reliability prediction of lead-free solder joint. Background research of fatigue models for lead free solder joint.is described in theoretic part Basic terminology and lead free soldering technology operations are mentioned in the theoretical part too. The practical part is dealing with observation of resistivity and solder joint strength during thermal cycling. Evaluation of results and experiments and posibility for future application of these results for fatigue model realisation is discussed in the end of this bachelor's thesis
