In this thesis, we give two simple and effective methods for constructing Kummer extensions of algebraic function fields over finite fields with many rational places. Some explicit examples are obtained after a practical search. We also study fibre products of Kummer extensions over a finite field and determine the exact number of rational places. We obtain explicit examples with many rational places by a practical search. We have a record (i.e the lower bound is improved) and a new entry for the table of van der Geer and van der Vlugt.

Abstract One of the ways for a speaker to make sense of an object or event in the real world is to make use of iconicity between two things. Through iconic metaphorical extensions, the speaker connects the object or event to something else. In this study, I consider how speakers form concepts through iconic metaphorical extensions, examining how they metaphorically extend one concept to another. I suggest that all speakers use the same ways of forming metaphorical extensions and control metaphorical extensions according to their intentions and contexts. Using basic and simple shapes (e.g. 0) and their related metaphorical expressions (e.g. `a circular argument'), I discuss the role of iconicity in metaphorical understanding, the relationship between concept and language, and metaphorical extensions as tools of concept formation. I conduct descriptive investigations using dictionaries and compare related senses for particular basic shapes between English and Japanese, looking at their polysemous networks and historical changes. Using questionnaires, interviews and tasks with native speakers of English and Japanese, I conduct experimental investigations to examine the speakers' associations in relation to basic shapes and the degree of iconicity in metaphorical extensions. This study suggests that concepts, although probably stored in the mental space, are recreated every time they occur. Concept formation through iconic metaphorical extensions must be dynamic because it is based on 'extensions' of existing concepts, and must be universal to all speakers because metaphorical extensions are among the most basic mental activities of human beings. I propose dynamic and universal models which represent the way in which a speaker forms concepts, connecting a linguistic form and a mental picture and controlling iconic metaphorical extensions. These models contribute to understanding both similarities and differences in use of metaphorical extensions between English and Japanese.

>Magister Scientiae - MSc / The aim of this dissertation is to calculate character tables of group extensions. There are several well developed methods for calculating the character tables of some selected group extensions. The method we study in this dissertation, is a standard application of Clifford theory, made efficient by the use of Fischer-Clifford matrices, as introduced by Fischer. We consider only extensions Ḡ of the normal subgroup N by the subgroup G with the property that every irreducible character of N can be extended to an irreducible character of its inertia group in Ḡ , if N is abelian. This is indeed the case if Ḡ is a split extension, by a well known theorem of Mackey. A brief outline of the classical theory of characters pertinent to this study, is followed by a discussion on the calculation of the conjugacy classes of extension groups by the method of coset analysis. The Clifford theory which provide the basis for the theory of Fischer-Clifford matrices is discussed in detail. Some of the properties of these Fischer-Clifford matrices which make their calculation much easier, are also given. We restrict ourselves to split extension groups Ḡ = N:G in which N is always an elementary abelian 2-group. In this thesis we are concerned with the construction of the character tables (by means of the technique of Fischer-Clifford matrices) of certain extension groups which are associated with the orthogonal group O+10(2), the automorphism groups U₆(2):2, U₆(2):3 of the unitary group U₆(2) and the smallest Fischer sporadic simple group Fi₂₂. These groups are of the type type 2⁸:(U₄(2):2), (2⁹ : L₃(4)):2, (2⁹:L₃(4)):3 and 2⁶:(2⁵:S₆).

Philosophiae Doctor - PhD / The aim of this dissertation is to calculate character tables of group extensions. There are several well–developed methods for calculating the character tables of group extensions. In this dissertation we study the method developed by Bernd Fischer, the so–called Fischer–Clifford matrices method, which derives its fundamentals from the Clifford theory. We consider only extensions G of the normal subgroup K by the subgroup Q with the property that every irreducible character of K can be extended to an irreducible character of its inertia group in G, if K is abelian. This is indeed the case if G is a split extension, by a well-known theorem of Mackey. A brief outline of the classical theory of characters pertinent to this study, is followed by a discussion on the calculation of the conjugacy classes of extension groups by the method of coset analysis. The Clifford theory which provide the basis for the theory of Fischer-Clifford matrices is discussed in detail. Some of the properties of these Fischer-Clifford matrices which make their calculation much easier are also given. As mentioned earlier we restrict ourselves to split extension groups G in which K is always elementary abelian. In this thesis we are concerned with the construction of the character tables of certain groups which are associated with Fi₂₂ and Sp₈ (2). Both of these groups have a maximal subgroup of the form 2⁷: Sp₆ (2) but they are not isomorphic to each other. In particular we are interested in the inertia groups of these maximal subgroups, which are split extensions. We use the technique of the Fischer-Clifford matrices to construct the character tables of these inertia groups. These inertia groups of 2⁷ : Sp₆(2), the maximal subgroup of Fi₂₂, are 2⁷ : S₈, 2⁷ : Ο⁻₆(2) and 2⁷ : (2⁵ : S₆). The inertia group of 2⁷ : Sp₆(2), the affine subgroup of Sp₈(2), is 2⁷ : (2⁵ : S₆) which is not isomorphic to the group with the same form which was mentioned earlier.

This thesis is divided into three parts. The first part is focused on a description of the formulation of the extension for viewers Internet Explorer, Opera, Safari 5, Mozilla Firefox a Google Chrome, on summary of the facilities of development of the extension for these viewers and on structure of the extension factually for Google Chrome. The second part describes the installation of the extension for Chrome with method of the unpack extension and with method from the Internet shop Chrome. There is also described a detailed formulation of the extension for Chrome with examples of the code source, with possibility of the implementation and the commentary insert into websites. It further describes contribution of the extension and contribution of this thesis. The target of this thesis is to get acquainted with problems of the formulation of the extension of plugins for viewers Chrome or Firefox and to formulate an application, which it will be able to add the commentary to contents of the website.

Thesis Theme is the reconstruction of the cultural house in Suchý Důl. The building is divided into a restaurant with rooms and multi-purpose hall with facilities. Reconstruction of the building is additional insulation of substructures, exchange floor structures, replacing ceiling structures, creating new roof construction, replacement of doors, windows and changing the layout. The reconstruction and extension of the part of the building.
