The thesis deals with second language acquisition (SLA) of Czech in Russian and English students. It presents the main theories of SLA (generative and cognitive approaches) and compares them to the results of author's research into L2 acquisition of Czech morphology and syntax in speakers of two typologically and structurally different mothertongues. It shows that language transfer plays an important role in SLA and that some of the generative assumptions about SLA that are claimed to apply universally cannot be proven for Czech.

The diploma thesis focuses on teaching grammar in the context of in-company language courses. What needs to be taken into consideration are both the psychological aspects of adult learners and the sociological characteristics of a typical course participant, their position of a client which is connected to high expectations of the service provided - language tuition. The role of the teacher in an in-company course is much less authoritative than in a traditional course and teachers become rather partners or coaches for the learners. The pedagogical research conducted among 172 Czech in-company learners with the help of an electronic questionnaire shows that the main aim of in-company students is to be able to communicate efficiently in real-life situations from their private and working lives. It is the role of the teacher, or the coursebook author, to choose which grammar structures are necessary to succeed in the respective situations. Therefore, the most suitable method for teaching grammar in the context of in-company courses is the Engage, Study, Activate method combined with the eclectic method.

This master's thesis offers a brief introduction to evolutionary computation. It describes and compares the genetic programming and grammar based genetic programming and their potential use in automatic software repair. It studies possible applications of grammar based genetic programming on automatic software repair. Grammar based genetic programming is then used in design and implementation of a new method for automatic software repair. Experimental evaluation of the implemented automatic repair was performed on set of test programs.

The main goal of this master thesis is introduction and investigation of extended version of jumping automata and grammars. New versions are primarily focused on bioinformatic applications - DNA computing. This thesis examine their power and other properties of new models and makes comparison with existing computer science models. Then thesis demontrates practical applications, specifically amino acid and protein detections inside DNA sequence and makes comparision with existing tools in DNA computing for example Mark´s probabilistic models.

This paper deals with problem of procedurally generated city. There are described steps of creation of city. These steps are: road generation, extraction of minimal cycles in graph, division of lots and generation of buildings. Road and buildings are generated by L-system. Our system generate a city from input images, such as height map, map of population density and map of water areas. Proposed approaches are used for implementation of application for generation of city.

The thesis deals with the employment of direct forms of presentation in the genre of hard news. The texts for the analysis were excerpted from the main British broadsheet newspapers. The classification of forms of presentation is based on Semino and Short (2004) and focuses on their deictic and syntactic properties, interpreted in terms of the pragmatic concepts of perspective, faithfulness claims and the role of the reported and reporting speaker. Attention is paid to various direct forms, including direct speech, free direct speech and combined forms, i.e. non-direct forms appearing with a partial direct quote. The thesis draws heavily on the work by White (1998), whose approach to genre is informed by the ideas proposed by the Sydney School and Systemic Functional Linguistics. Hard news is characterised by the orbital generic structure, consisting of the nucleus and a number of specifying satellites (White 1998). The occurrence of direct and combined forms of presentation is explained by their deictic, syntactic and pragmatic properties, the generic role and characteristic features of the nucleus and individual satellites, and the overall function of hard news. The function of hard news and forms of presentation is also discussed in terms of the more general concepts of heteroglossia, dialogue...

This PhD thesis deals with the use of structural methods of objects identification for industrial robots operation. First, the present state of knowledge in the field is described, i.e. the whole process of objects recognition with the aid of common methods of the syntactic analysis. The main disadvantage of these methods is that is impossible to recognize objects whose digitalized image is corrupted in some ways (due to excessive noise or image disturbances), objects are therefore deformed. Further, other methods for the recognition of deformed objects are described. These methods use structural description of objects for object recognition, i.e. methods which determine the distance between attribute descriptions of images. The core part of this PhD thesis begins in Chapter 5, where deformation grammars, capable of description of all possible object deformations, are described. The only complication in the analysis is the ambiguity of the deformation grammar, which lowers the effectiveness of the analysis. Further, PhD thesis deals with the selection and modification of a proper parser, which is able to analyze a deformation grammar effectively. Three parsers are described: the modified Earley parser, the modified Tomita parser and the modified hybrid LRE(k) parser. As for the modified Earley’s parser, ways of its effective implementation are described. One of the necessary parts of the object recognition is providing the invariances, which this PhD thesis covers in detail, too. Finally, the results of described algorithms are mentioned (successfulness and speed of deformed objects recognition) and suggested testing environment and implemented algorithms are described. In conclusion, all determined possibilities of deformation grammars and their results are summarized.

This document deals with introduction focused on pragmatically oriented research at branch of theoretical computer science and with presentation of designed methods for chosen application topics. At this study the theoretical subject is represented by kind of generative system - multisequential grammar and application topics are chosen according to possibilities supported by multisequential grammars. In order to follow results published by Thompson (see [9]), Lindenmayer (see [26]), Mandelbrot (see [8]) and also studies published by Morneau (see [17]), which shows the relation between natural laws and human discipline - mathematics, we study the applications of multi-sequential grammars from two points of view: generative L-systems (which further includes applications of fractal geometry and biomathematics) and natural language processing (which further includes the design of proper abstract language). Some problems related to compiler construction are also mentioned.
