Sequential and Parallel Grammars: Properties and Applications
Klobučníková, Dominika ; Martiško, Jakub (referee) ; Meduna, Alexandr (advisor)
This thesis deals with the topic of sequential and parallel grammars. Both of these groups cover a large number of grammar families, most of which, however, are not widely used because of the difficulties related to their processing. The thesis examines some of these grammar types, such as scattered-context grammars, multigenerative systems, and interactive L-systems, with focus on their normal forms. Subsequently, it introduces a set of algorithms utilising properties of the discussed grammar types as well as their normal forms. These algorithms are based on the Cocke-Younger-Kasami algorithm for context-free grammars, and are capable of parsing any grammar in the corresponding normal form. Finally, a program implementing the proposed algorithms is presented.

Formal Language Theory Applied in Musicology
Straková, Tereza ; Tomko, Martin (referee) ; Meduna, Alexandr (advisor)
The aim of this thesis is to apply formal models in music. Specifically, it concentrates on the generation of musical strings. In the thesis, a scattered context grammar for generating variations of a musical motif was designed. Next, an algorithm was designed for table driven parsing of the grammars. The algorithm uses a list of stored rules, which allows it to work with only the top of a stack. The algorithm was implemented as an application, which allows the generated motifs to be played or saved.
