Analog distortion musical signals
Růžička, Matěj ; Kubánek, David (referee) ; Vrba, Kamil (advisor)
In this bachelor thesis I studied the differences in sound of valve amplifiers and solidstate amplifiers, causes of those differences, mathematical modelling the transfer characteristic of valve amplifier and then modeling it with simple diode limiter, which used several types of semiconductor diodes, Properties of those diodes were measured as well. Then I constructed limiters for both polarities of input signal, which had non-linear transfer characteristics similar to the valve amplifier and I evaluated their qualities. Then I measured simple amplifier with bipolar transistor, JFET N-channel transistor and optocoupler, Furthermore, I modified triangle-to-sine converters with bipolar transistor, JFET N-channel transistor, measured and evaluated their transfer characteristics. At the end of this bachelor thesis I described designing a diode-based functional converter and converter made from several bipolar transistors, both of these had similar shape of transfer characteristics and I evaluated their qualities by comparing weighted harmonic distortion of the output signal with output signal of tube amplifier.
Study of (bio)molecular interactions and enzymatic reactions by capillary electrophoretic methods
Růžička, Martin
Non-covalent interactions participate in majority of processes in living organisms. The strength of interaction between (bio)molecules can be characterized by binding constants of respective complexes, which can be determined by variety of physico-chemical methods. From these methods, capillary electrophoresis features several advantages: (1) interactions takes place in aqueous solutions between free molecules without necessity of their immobilization, (2) short analysis time, (3) small consumption of analyzed compounds, and (4) easy automation of analyses. Within this dissertation thesis, methods of partial-filling affinity capillary electrophoresis (PF-ACE) were developed for study of interactions between double-strand DNA oligonucleotides and well characterized intercalator ethidium bromide as a model compound. Subsequently, binding constants of oligophenylene derivatives complexes with DNA oligonucleotides were determined. The PF-ACE method was optimized for study of enantioselective interactions between helquats and selected chiral acidic aromatic analytes. Several compounds whose enantiomers were separated using helquats as chiral selectors were identified. Capillary electrophoresis was applied as a separation analytical method for monitoring of peptide substrate cleavage by rhomboid...
Compulsory use of trademark and its demonstration under Czech law and the EU law
Navrátilová, Andrea ; Růžička, Michal (advisor) ; Císařová, Zuzana (referee)
Compulsory use of trademark and its demonstration under Czech law and the EU law The aim of this thesis is to introduce the institute of compulsory use from the perspective of Czech and EU law and subsequent proof of this obligation. The thesis consists of a brief introduction and six chapters, the sixth chapter is the conclusion. The first chapter is a general introduction to the issue of trademarks and aims to briefly inform about the concept of the trademark, its functions and the Czech and EU legislation on the issue of trademark law. It also describes the application procedure in the Czech Republic and the rights and obligations of the owner. The next chapter is about the right of the owner to use the trademark, both in terms of the positive and the negative definition of this right. Following part of thesis is devoted to the main topic of the thesis, the obligation to use the trademark. It speaks about the importance of that obligation, whose goal is maintaining registration of those marks which are actually used. Also, this chapter is focused on the term "genuine use of the trade mark", which is a condition for fulfilling the obligation of use. Another term that needs to be clarified is "proper reasons for non-use". Only their existence excuses the non-use of the mark and, if they are proven...
The relationship between rights of designation and unfair competition law
Ferancová, Eva ; Růžička, Michal (advisor) ; Císařová, Zuzana (referee)
The topic of this diploma thesis is the relationship between rights of designation and unfair competition law. The thesis is divided into five chapters. The first two chapters define rights of designation and unfair competition law in general and the following chapters concentrate on the relationship between them. The first chapter focuses initially on the place of rights of designation in the system of intellectual propert y law and afterwards it concentrates on particular rights of designation, i.e. trademark, designation of origin and geographical indication. This chapter deals with characteristic features of the rights of designation and differences between them and national, international and european legislation. The emphasis is also put on current issues, that are related to the rights of designation. Chapter two is devoted to unfair competition law. This chapter focuses on legislation of unfair competition and the concept on which unfair competition law is based (that is combination of general clause and non-exhausting list of merits). Subsequently, it defines subjects of the unfair competition and claims that a subject affected by the unfair competition can make. The third chapter, which presents crucial part of this thesis, concetrates on the relationship between rights of designation and...
The methodology for bit-level preservation of digital data
Růžička, M. ; Miranda, Andrea ; Hejtmánek, L. ; Vašek, Zdeněk ; Krejčíř, V. ; Bartošek, M.
The aim of the digital data bit-level protection methodology is to provide recommendations for implementing Long Term Preservation (LTP) storage. The methodology provides guidance on how to address the problem of bit protection of digital data in the environment of Czech libraries on the basis of good practice in this area available in the Czech Republic and worldwide. At the same time, this methodology is connected to project ARCLib , which aim is to develop open source LTP system. For wide availability to the libraries of the Czech Republic and elsewhere, the whole recommendation is based on freely available technologies with open source text and licenses allowing further development and adaptation to the needs of the user.

Legal protection of domain names in relation to rights of designation
Řehounek, Dominik ; Růžička, Michal (advisor) ; Dobřichovský, Tomáš (referee)
Legal protection of domain names in relation to rights of designation Abstract The diploma thesis focusing on the legal protection of domains in relation to the rights of designation has an ambition to offer its readers a comprehensive view of this issue. The work is divided into two basic parts, namely technical and legal parts. In the technical part, attention is paid to both the technical background of the domains, the functioning of the domain name system as well as the individual concepts such as the difference between the domain and the domain name. Legal part is divided into two chapters. The first chapter seeks, in particular, to anchor domains within the legal order, while the other deals with their differences with respect to the rights to designations and possible collisions with them. In the first chapter, apart from a bit of history, the technical functioning of domains within the domain name system is described. Emphasis is placed on the hierarchical structure and explanation of the basic principles. The explanation also deals with different types of domains and their differences. The space is also dedicated to the registration process. In the second chapter it deals with the status of domains, respectively domain names within the legal order. It polemize the existence of absolute rights and...
The relationship between trademark protection and copyright protection
Crháková, Blanka ; Růžička, Michal (advisor) ; Dobřichovský, Tomáš (referee)
RESUMÉ
 The name of the thesis: The relationship between trademark protection and copyright protection This diploma thesis deals in a complex way with the system of relationship between trademark protection and copyright protection within Czech law. The diploma thesis is based mainly on two acts - Act No. 121/2000 Coll., On copyright protection, and Act No. 441/2003 Coll., On trademark protection. It also reflects European law including actual case-law. The main goal of the thesis is to show how both protections work, their mutual relation, eventually how and in which situations their convergence happens and what can be the consequences of it from the protection point of view. In the first chapter of my thesis we find introduction that brings the subject to the topic, including aim of the thesis. After that comes seven main chapters and a final conclusion. Initially in chapter two and three of my thesis, I define the basic concepts dealing with Intellectual property and law related to intangible property. Subsequently description of the simultaneous operation of both protections is discussed and based on that their similarities and differences are highlighted. The focus is on analysis of both protections, subjects of both protections, their beneficiaries, formation, duration, means and international...
Private law aspects of trademark protection
Beňasová, Kateřina ; Růžička, Michal (advisor) ; Císařová, Zuzana (referee)
Název rigorózní práce v anglickém jazyce, abstrakt v anglickém jazyce a 3 klíčová slova v anglickém jazyce Private law aspects of trademark protection Abstract This thesis focuses on law of designations in a form of trademarks. Historically, trademark law could be classified as public law rather than private law, however recently the perception has changed as legal doctrine observes developing private law aspects. This thesis centres on private law aspects of trademark law, in particular private law aspects of trademark protection. Its aim is to provide complex overview of means of trademark protection from private law point of view. Relevant provisions include exclusive private rights of trademark's owner and their protection. The owner can protect their rights in various means. First of all, as detailed in the second chapter, the owner of a trademark can prevent future trademark from registration with the trademark registry through filing an objection to opposition proceedings held before Industrial Property Office, provided the future trademark contradicts the older one. Through such objection the owner usually protects their older trademark before registration of new trademark (which would harm their trademark's distinctive character or which would unfairly exploit it) with the trademark registry....
Modelling of heterogeneous catalytic reactions in chemical reactors
Orava, Vít ; Hron, Jaroslav (advisor) ; Pavelka, Michal (referee) ; Růžička, Marek (referee)
This thesis consists of two parts discussing modelling of heterogeneous catalytic reactors. In the first one, an industrial prototype of a fluidized bed reactor serving as a hydrogen generator based on endothermic decomposition of formic acid is studied. After initial determination of the main reactor characteristics a system of nine con- stituents is derived and, consequently, reduced to a three phase flow. The solid and bubble particles immersed in a liquid are modelled by the Basset-Boussinesq- Ossen equation. Furthermore, an averaging technique is used to derive a three phase Euler-Euler model. Finally, numerical computations with a verification towards the measurements and a CFD analysis are proceeded. The second part discusses interfacial transport phenomena between a bulk and catalytic surfaces of a reactor mediated via the boundary conditions. The constitu- tive relations, that by construction comply with the second law of thermodynamics, follow from the specification of suitable thermodynamic potentials together with an identification of the bulk and surface entropy productions. The derived model is suitable for further analysis providing clear guidelines for the incorporation of the Langmuir-type adsorption model as well as other sorption models. Keywords: Heterogeneous catalysis, multi-phase...
