Fingerprints Generator
Chaloupka, Radek ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
Algorithms for fingerprints recognition are already known for long time and there is also an effort for their best optimization. This master's thesis is dealing with an opposite approach, where the fingerprints are not being recognized, but are generated on the minutiae position basis. Such algorithm is then free of the minutiae detection from image and enhancements of fingerprints. Results of this work are the synthetic images generated according to few given parameters, especially minutiae.

Robots of the present and the future
Rehák, Jozef ; Langerová, Petra (referee) ; Jašková, Jana (advisor)
Tato semestrální práce je zaměřena na téma robotů současnosti a budoucnosti. Cílem práce je seznámit čtenáře s roboty a teoreticky popsat stav robotů v současnosti a předpovědi pro budoucnost robotiky. Na začátku práce je stručně popsaná historie robotů a vysvětluje jméno, které dostali. Následně je popsán současný stav robotiky, a roboti jsou rozděleni do skupin, které nejlépe odpovídají jejich schopnostem. Dále spolu s technologickou Singularitou jsou diskutovány předpovědi budoucnosti robotiky. Tyto diskutované předpovědi navíc ukazují potenciál robotiky stát se součástí samotné existence lidí tím, že se lidé stanou kyborgem nebo jsi digitalizují mysl a nahrají ji do cloudu. Tímto způsobem je prezentována možnost nesmrtelnosti nebo alespoň prodloužení životnosti. Na závěr práce je uveden možný první příklad produktu budoucnosti, který se bude hromadně vyrábět.

Fingerprint biometry
Smékal, Ondřej ; Drahanský, Martin (referee) ; Fedra, Petr (advisor)
Algorithms designed for identification and verification persons by fingerprints recognition are spread and used as in forensics aplications as in private sector for a long time. The aim of this thesis is to make us aquainted with various aplicated mathematic models of fingerprint processing in digital way. Second task is the presentation algorithmic solution of chosen subject identification procedure by force of Fingerprint matching. Algorithm is solid in the development environment platform Matlab.

Fingerprint Classification
Kostiha, Martin ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
Automatic identification based on fingerprints requires the input fingerprint to be matched with a large number of fingerprints stored in a database. Fingerprint classification provides an important indexing mechanism in fingerprint databases that reduces the search time and computational complexity. This thesis is dealing with Galton-Henry's classification system. The classification method is based on orientation field and detection singularities using Poinaceré index.

In the process
Volková, Markéta ; Velická, Erika (referee) ; Korbička, Pavel (advisor)
My bachelor's thesis is an object responding to the space that surrounds it. It points out the contradiction between organic and austere form. In my work, I materialize abstract experiences through metonymically selected building elements related to the places in which I have these experiences. As an extraction of elements appearing in the architecture of the Southern Mediterranean, a form of ornament appears in the work, which is understood by a figurative comparison to the experience of travelling on holiday. Another element, representing a figurative experience of returning "to reality", are the lux spheres. Their character is linked to the architecture of Central Europe. I explore the relationship between the different types of buildings, which I then freely develop. My perception of reality enhances the recognition of the new with the already known. I let the objects represent and capture these two opposing perceptions with implications and emphasis on their differences. In this way, I come to find in my work a similarity between geometric austerity, which signifies perfectionism, and the intuitive unfolding of ornament, which inserts the theme of organicity into the object. An important aspect of the thesis is processuality. I understand my work as a border between conceptual and intuitive process.

Exact spacetimes and their physical properties
Veselý, Jiří ; Žofka, Martin (advisor) ; Hennigar, Robie (referee) ; Tahamtan, Tayebeh (referee)
Motivated by our desire to find generalizations of the Bonnor-Melvin spacetime, the thesis investigates seven static, cylindrically-symmetric and electrovacuum exact solutions to the Einstein-Maxwell equations. They contain a magnetic field and six of them also include the cosmological constant. After discussing some of the methods we use during our investigation, we present the basic properties of the spacetimes, and for each of them we also study charged test particle motion and their admissible shell sources composed of particle streams. We also perform numerical computations to determine whether the equations admit more general solutions than the exact ones we derived. 1

Autonomous Weapon Systems as the next revolution in warfare and implications of technology deployment for global security
Kvasňovský, Tomáš ; Kučera, Tomáš (advisor) ; Solovyeva, Anzhelika (referee)
This thesis addresses developments in Artificial Intelligence and the increasing trend of robotization and autonomization of military forces in the context of Revolution in Military Affairs. It examines and categorizes different approaches to concepts of AI, autonomy and RMA in the public debate and academic and military literature. It further explores potential impacts and challenges of AI and its weaponized subset - Autonomous Weapon Systems on civil-military relations, legal and ethical norms, arms control regime and general security domain. Building upon findings from previous chapters, AI and AWSs are analyzed in a context of RMA and broader socio-economic context. Specifically, AI-enabled autonomy is compared with aspects of existing remotely controlled systems. The thesis comes to a conclusion that AWSs are harbingers of the next RMA and AI has the potential to match the importance of Neolithic, Industrial and Information revolution.

Singular points of algebraic varieties
Vančura, Jiří ; Příhoda, Pavel (advisor) ; Šťovíček, Jan (referee)
This thesis is an introduction to exploring singularities of algebraic varieties. In the first chapter, we state basic definitions and theorems necessary for exploring singularities. Firstly, we define algebraic varieties and their corresponding ideals and explain the term of Krull dimension. We also focus on the local properties of varieties. In the second chapter, we begin by examining the term of singularity in detail and introducing methods for searching for singularities. We prove two theorems about the shape and the dimension of singularities. In the second part, we prove theorems about the zero divisors, which enable us to define Cohen-Macaulay and Gorenstein rings. We use them to roughly classify singularities of algebraic varieties.

Rationale of eternity in times
Hlavešová, Ilona ; Vogel, Jiří (advisor) ; Vik, Dalibor (referee)
The thesis "The justification of eternity in times" addresses the relationship of the entity whose existence is modally necessary to the times of the entities of contingent existence, whose existence is defined by creation and termination, i.e., by the two poles of existence. The solution of this relationship is the answer to Panneberg's question about the relationship of eternity to the space-time structure of the universe. The approach to solving this problem is analyzed in the introductory chapter. Entities of contingent existence - beings - can be considered from the point of view of existence as polar entities, while the modally necessary one, which neither comes into existence nor ceases to exist, spans in its existence the poles of existence of all beings - it is therefore supra-polar in this sense. Time is needed to express the impermanence of the existence of beings. The fact that entities of contingent existence must exist in time raises the question of the relation of the modally necessary entity to time. The formal-logical expression of the relation of modally necessary entities to the times of modally contingent entities is discussed in second chapter. Sufficient conditions are given here for such an existence of a modally necessary entity which can be said to be of unbounded duration...
