Deinterlacing in uncompressed digital video sequences
Meňhart, Pavel ; Kratochvíl, Tomáš (referee) ; Slanina, Martin (advisor)
Interlacing is the process of frame scanning and frame displaying being based on the even and uneven lines‘ interchanging. This framework originated along with the PAL and NTSC television standards‘ formation in the course of 1930s. The process mentioned above stopped frames displayed on older TV sets from flashing. Nevertheless, there is a disadvantage of the frame processed after this manner, consisting in its attribute to be displayed in a clean-cut way just on classical TV sets. However, plasma and LCD television appliances, projectors and computer monitors always display the entire frame all at once, therefore composing it of the both fields, yet not being acquired concurrently, differing in moving objects‘ positions, moreover their contours are doubled, frayed and unfocussed. This master´s thesis deals with fundamentals of the interlaced video signal‘s formation, problems coming about at featuring the interlaced video like this, followed by operating methods of deinterlacing itself. In conclusion, there are my own softwares presented, having been developed in MATLAB computer environment and software command language C, and implementing some of the operating methods designed for deinterlacing in uncompressed digital video sequences.

Panoramatic View Reconstruction
Kuzdas, Oldřich ; Kohoutek, Michal (referee) ; Říha, Kamil (advisor)
This paper deals step by step with process of stitching images taken by perspective camera rotated by its optical center into the panoramic image. There are described keypoint searching algorhytms, possibilities of calculating homography matrix and methods of eliminating unwanted seams between source images in final panoramic image. A part of this paper is also standalone application in which are implemented some algorhytms described in the work.

School, the Foundation of Life – a Complex of Educational Buildings in Ostrava, Cerna louka
Britanová, Eva ; Magnusek, Pavel (referee) ; Nový, Vítězslav (advisor)
New komplex of school buildings in Ostrava on Černá louka is the school with perspective for the future. It provides overall education and concentrate on maximum efficiency of learning proces. The idea links the theory with practical demonstration and intense learning with relaxation in nature enviromnemt. The teaching system support the independent activity of each individual and self-realization for everyone. The school allows some variability of internal organization of space and take into consideration the technology development and the capacity of youngsters to understand it and embrace it.

Design of Hand Blender
Kalenský, Ondřej ; Buganská, Tamara (referee) ; Sládek, Josef (advisor)
This bachelor‘s thesis deals with the design of ahand blender. The main problems it covers are designing with consideration to blind and old people, clear and natural control and more options for holding the device. The thesis discovers the essence of the process of blending and whisking. Based on this knowledge, the ambition behind the design of the product is to form anew shape which is in harmony with its function. The thesis is marginally focused on the theory of designing and developing anew product and it describes the practical usage of user-friendly design rules.

Blending within the neologism excerption database
Neprašová, Renáta
This paper focuses on blending as a type of mechanical compounding. The researched material results from the internal neologism excerption database of the current lexicology and lexicography department of ÚJČ AV ČR v. v. i. (Institute of the Czech Language of the AS CR, v. v. i.), whose lexical content arises by excerption of mainly journalistic texts. The paper presents the types of lexemes arised from blending, which is found in the database. The formation and processing of neologism material in the database are based on these examples. The material is classified according to the formation to blends of the Czech and foreign-language components, hybrid blends, blends of proper names and geographical names and the unclassifiable puns. The material is analyzed in terms of semantic and by occurrence of lexemes in specific types of text.

From irregular word formation: mechanical shortening and blending
Šimandl, Josef
After a survey of irregularities in the regular derivation, a survey of irregular ways is given, following Czech grammatographical tradition. Some remarks to the mechanical shortening follow. From specifically English ways to form new words, back derivation is mentioned; however, the main topic is blending. Czech equivalents to blending are estimated and the winner for now is přiklánění, “inclining”, because the notion of each single element continues in the blend and so does the form to a diverse extent. Examples are given how insufficient is to distinguish between “portmanteaux” and “telescops”, for there are more ways how to incline words closer to each other. A new term “hinting” is coined for the semantic side of blending: each blend hints its basic words. The frequency of mechanical shortenings and blends cannot be pinpointed, due to uniqueness of creatively formed words. The question, how broad is the periphery (not-formed words, words formed from an obsolete base or/and after obsolete models, mechanically shortened words, blended words ...) against the centre of regularly well-formed words, remains unanswered, but not forgotten.

Modelování přírodních katastrof
Zuzák, Jaroslav ; Zimmermann, Pavel (advisor) ; Masec, Frant (referee)
This thesis introduces various approaches to natural catastrophe risk assessment in (re)insurance environment. Most emphasis and further elaboration is put on probabilistic models in comparison to the standard model as proposed by Solvency II. The outcomes of natural catastrophe modeling play an important role in the design of proper actuarial models related to catastrophe risk. More specifically it is shown that they can be entirely understood in a wider actuarial context, namely risk theory. Within the Solvency II framework, probabilistic model outcomes are translated by means of the proposed decomposition methodology putting them into a similar language of the standard formula in order to create the ability to compare different results implied by either probabilistic model or standard formula. This enables both comparison of the implied dependence structure of probabilistic model to standardized correlations assumed in Solvency II, and scenario year loss factors of Solvency II to implied damage factors of probabilistic models in defined cresta zones. The introduced decomposition methodology is illustrated by flood and windstorm model outcomes calculated on exposure data of Czech insurance companies and compared to the respective standard formula parameters and outcomes. Finally, other applications of the proposed decomposition methodology are introduced, such as measurement of diversification effect or blending of different results calculated by different models or even approaches to natural catastrophe risk assessment.

Application of the blending problem into the marketing campaign making
Záhorovský, Radek ; Skočdopolová, Veronika (advisor) ; Šindelářová, Irena (referee)
Application of the blending problem is one of the basic tools used in the marketing campaign making. It uses the theoretical knowledge of the linear programming in the real-world problem. This method is used for the optimization of required goals accepting the given budget and conditions. Linear programming is one of the tools suitable for maximizing the efficiency of the spent costs when scheduling the budget into the different media types. Media agencies normally use sophisticated software based on the linear programming methods. The results can be implemented into other specific situations and for other companies with the same kind of product. After that results can be analyzed for the future use. Basic problem of application of the blending problem is the fact that it is difficult to include all the factors affecting the impact of marketing campaign into the mathematical model.

Solving of blending and diet problems
Křenková, Michaela ; Fábry, Jan (advisor) ; Čížek, Ondřej (referee)
The aim of this work is to ascertain in which situations can be used models of blending and diet problems. It will draw together different examples and describing steps in solving them. The work is divided into two main Chapters: - Blending Problems, and Diet Problems. Both types of linear programming problems are first briefly discussed, which is then followed by the creation of a mathematical model, with explanations for creating constrains and objective functions. Examples are solved with optimizing software LINGO.
