Compiler of a Language with User-Defined Syntax for New Constructs
Kuklínek, Lukáš ; Křivka, Zbyněk (referee) ; Kolář, Dušan (advisor)
Tato práce si klade za cíl navrhnout a implementovat experimentální programovací jazyk s podporou uživatelsky definovaných syntaktických konstrukcí. Nový jazyk je kompilován do nativní binární podoby a vyžaduje statickou typovou disciplínu v době překladu. Jazyk se skládá ze dvou hlavních komponent. První z nich je minimalistické jádro založené na principech zásobníkově orientovaných jazyků. Druhou částí je mechanismus pro definici nových syntaktických konstrukcí uživatelem. Poté jsou shrnuty poznatky nabyté při návrhu a experimentování s prototypem překladače tohoto jazyka.

Modified Parsing
Sopuch, Zbyněk ; Rychnovský, Lukáš (referee) ; Meduna, Alexandr (advisor)
This project deals with modification of syntax analysis. I realize three modifications of bottom up algorithm. First way is modification of Cocke-Younger-Kasami algorithm, second is based on EOL system and third is based on ETOL system.

Parsing Based on Multigeneration
Kyjovská, Linda ; Přikryl, Zdeněk (referee) ; Lukáš, Roman (advisor)
This work deals with syntax analysis problems based on multi-generation. The basic idea is to create computer program, which transforms one input string to n -1 output strings. An Input of this program is some plain text file created by user, which contains n grammar rules. Just one grammar from the input file is marked as an input grammar and others n -1 grammars are output grammars. This program creates list of used input grammar rules for an input string and uses corresponding output grammar rules for the creation of n -1 output strings. The program is written in C++ and Bison

Grammar Systems and Parsing Based on Them
Handlíř, Jaroslav ; Zámečníková, Eva (referee) ; Meduna, Alexandr (advisor)
This work is devoted to grammar systems. Defines cooperating distributed grammar systems CD and parallel communicating grammar systems PC in conjunction with context-free grammars. It also examines their principles and generative forces in different regime and to different languages. Studying the use of grammatical parsing systems. It focuses primarily on top-down parsing and precedential bottom-up analysis in conjunction with the PC grammar systems.

Advanced Error Recovery during Top-Down Parsing
Obluková, Alena ; Kolář, Dušan (referee) ; Meduna, Alexandr (advisor)
Parser is one of the most important parts in compiler since Syntax-Directed Translation is often used. This approach means that parser controls semantic actions and generation of syntax tree. When the input contains an error, parser cannot continue and the whole compiler has to stop. Therefore, it is important to have parser with error recovery, so when error occurs parser is able to continue. There are several error-recovery strategies and methods. In this paper is described Acceptable-sets derived from continuations specifically continuation in LL parsers. However it is not so well known method it is easy to explain and to implement. It can be used in the lesson to demonstrate error recovery in top-down parser.

Combined Parsing Based on Grammar Systems
Caha, Petr ; Solár, Peter (referee) ; Meduna, Alexandr (advisor)
This thesis deals with a combined parsing based on grammar systems. Introduces modified method of classical grammar systems. At first they will be theoretically described and in the next part they will be implemented for parsing. The basis for the parser is a cooperating distributed grammar system. Implementation uses recursive method and case analysis. The parser is universal, applicable to any grammar systems based on context-free and some not context-free.

Script Language for Image Processing
Crlík, Radek ; Španěl, Michal (referee) ; Zemčík, Pavel (advisor)
This bachelor thesis deals with capabilities of scripting languages and their types. Specifically with design of one such language suitable for image processing. The goal was to create a language small enough, but easy to use. One of the requirement was to utilize OpenCV library, for which the resulting code would be as short as possible. First part deals with descriptions of scripting languages, their main philosophy and options of language processing by the computer. Second part contains description of the designed language. Last part documents achieved goals and possible ways how to extend the language even further.

Deep Syntax-Directed Translation
Senko, Jozef ; Kučera, Jiří (referee) ; Meduna, Alexandr (advisor)
This thesis is a continuation of my bachelor thesis, which is dedicated to syntax analysis based on deep pushdown automata. In theorical part of this thesis is defined everything fundamental for this work, for example deep syntax-directed translation, pushdown automata, deep pushdown automata, finite transducer and deep pushdown transducer. The second part of this thesis is dedicated to the educational program for students of IFJ. In this part is defined strucure of this program and its parts. All part of program are analyzed from a theoretical and practical point of view.

Using structural method for objects recognition
Valsa, Vít ; Heriban, Pavel (referee) ; Šťastný, Jiří (advisor)
This diploma thesis deals with posibilities of using structural methods for recognition objects in a picture. The first part of this thesis describes methods for preparing the picture before processing. The core of the whole thesis is in chapter 3, where is analyzed in details the problem of the formation of deformation grammars for parsing and their using. In the next part is space for syntactic parser describing the deformation grammar. The conclusion is focused on testing the suggested methods and their results.
