Numerical calibration of material parameters of selected directional distortional hardening models with combined approach using both distorted yield surfaces and stress-strain curves
Hrubý, Zbyněk ; Plešek, Jiří ; Parma, Slavomír ; Marek, René ; Feigenbaum, H. P. ; Dafalias, Y.F.
The plastic strain induced anisotropy is a well-known phenomenon in manufacturing and directional distortional hardening represents a very promising way to capture real plastic behavior of metals. Many papers were published in the past typically extending the von Mises yield criterion with directionally dependent internal variable and defining yield point at the basis of plastic strain offset. Material parameters of these models were typically calibrated at the basis of deformed yield surfaces only, which – as revealed – could lead to certain discrepancies in simple stress-strain response. Presented paper introduces a numerical calibration approach taking both distorted yield surfaces and stress-strain curves information into account. Besides the calibration procedures, innovative applications of experimental techniques such as the acoustic emission for an acquisition of yield inception and plastic straining, convexity of the models, or numerical implementation of these models are discussed.

Residential Building
Voráč, Roman ; Sedmidubský, Jaroslav (referee) ; Sukopová, Dáša (advisor)
The apartment house is designed as a full-basement structure, with one underground storey and two above-ground storeys. The access to the building is either by a steel staircase or barrier-free, by a steel ramp. Cars enter the basement by a one-way ramp. The main entrance to the building is located on the first above-ground storey and is connected to the stairwell which serves as the principal vertical communication. The basement floor houses a parking lot, supporting facilities, cellars, and a boiler room. The first floor houses offices, including supporting facilities, and two apartment units, one comprising two rooms with kitchenette, the other a 3+1 (two-bedroom) unit. In addition, there is also a pram room. There are two 3+1 (two-bedroom) units on the second floor. Each apartment has its own balcony. The facade of the building is segmented, serving as a contact thermal insulation system. The building has a saddle roof, covered with gray-coloured seamed metal sheet roofing. Its slope is 13°. The building lies on ribbon foundations and a bearing plate. The structural system is based on brickwork consisting of ceramic building blocks, supplemented by reinforced concrete on the basement floor, and makes use of an outside contact thermal insulation system. The roof structures are represented by reinforced concrete monolithic ceilings. The load-bearing structure of the roof consists of a nailed roof truss girder, with the bottom flange of the girder carrying an SDK soffit – the ceiling structure of the second floor. The building will have a central heating system comprising an electric boiler with an accumulation tank located in the boiler room on the basement floor. Horizontal utility lines are bundled, with two main utility nodes located between apartment units.

Cochlear implant by adult
Kratochvílová, Tereza ; Hádková, Kateřina (advisor) ; Durdilová, Lucie (referee)
Bachelor thesis "The cochlear implant in an adult deaf" deals primarily with the cochlear implant. The most extensive part of the thesis talks about this topic, which also talks about the development and design of cochlear implants, explains the difference between cochlear implantation and tribal implantation and describes operation of implant and the subsequent setting of the implant. This section is also dedicated to binaural cochlear implantation, myths of cochlear implants and problems which are implanted meet. Bachelor thesis further defines an adult age and acquaints with the problems that loss of hearing in adulthood brings, suggests the possibilities of communication with a deaf person and mobility aids, which cochlear implant users use. The aim of this thesis is to map the level of hearing by adult with cochlear implant and the findings of the current problems by adult users of cochlear implants by questionnaire and interview.

Binominal phrases in Dutch
Borůvková, Markéta ; Křížová, Kateřina (referee) ; Hrnčířová, Zdeňka (advisor)
The presented diploma thesis is concerned with the group of phraseological combinations, namely binominal phrases in Dutch. Binominal phrases are compared to Czech; the goal is to investigate morphosyntactic and semantic-lexical congruence and difference. Theoretical part deals with morphological, syntactical and semantic description of phraseological pairs. At the same time, general characteristics and classification of phrasemes, accompanied by a brief historical overview, has been put together. Last part of the theoretical chapter is concerned with the types of equivalence. Practical part includes a corpus of Dutch phraseologisms and their Czech translations, which are distributed to three groups according to the degree of equivalence. The corpus has been set up manually, the main source being Van Dale Idioom Woordenboek. Further on, it was expanded by additional phrasemes taken from Nederlandse Spreekwoorden, spreekwijzen, uitdrukkingen en gezegen by F.A: Stoett, as well as by expressions from three websites, which contain lists of proverbs. In total, the corpus contains 286 Dutch binominal phrases, which are in the practical part subsequently analyzed according to the type of equivalence. 22% out of all binominal pairs are marked by total phraseological equivalence. This type of equivalence subsumes...

Horizons and ruins. The visible and invisible in the early modern visual culture
Hájek, Václav ; Konečný, Lubomír (advisor) ; Wittlich, Petr (referee) ; Lahoda, Vojtěch (referee)
My thesis deals with one specific pictorial motif from nineteenth century (horizon contra ruin) which represents and brings questions into an early modern visual culture. The visual culture includes a set of representations (artefacts, mass images, visual signs etc.) and also methods of a visual perception and reception. This text has an objective to watch, how is a concrete historical variant of the visual culture by reflexive manner reflected and construed in visual artefacts themselves (in a relevant theoretical context).
