Photovoltaic System Proposal for Commercial Building in Accordance with Applicable Rules for Energy Savings Program
Zeman, Daniel ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
Main purpose of the thesis is to create proposal of the photovoltaic hybrid system for commercial building in accordance with applicable rules for energy savings program. The introductory part of the thesis describes the rules regarding the photovoltaic system parts. The next part of the thesis describes the available technical solution for realization of the photovoltaic system design and the possibilities of electric energy accumulation in these systems and how to deal with power overflows using the power flow controller and what is the negative impacts on the distribution network when switching the connected load. In the next part the design of the PV system is carried out according to the valid assumptions described in the theoretical part of the thesis. Verification of power flow controller and measurement results in UEEN laboratories. The last part of the thesis is an evaluation of the economic part of the proposed system.

Extraction of multilingual valency frames from dependency treebanks
Faryad, Ján ; Zeman, Daniel (advisor) ; Lopatková, Markéta (referee)
Multilingual valency dictionaries provide helpful information about correspon- dence of valency frames (verbs and their arguments) across various languages. This work aims at developing a program that automatically creates a multi- lingual valency dictionary, based on parallel treebanks annotated according to Universal Dependencies. This task includes monolingual extraction of va- lency frames and their cross-lingual linking. Various methods for solving the task are analysed and implemented. The work includes both general, language- independent approach and additional language-specific extensions, provided in particular for English, Czech and Slovak. The methods for linking the valency frames include using word alignment, morphological and syntactic information contained in the UD annotation or similarity of verbs between related languages. The quality of the solution is evaluated by multiple established metrics on man- ually annotated data or by comparison with an existing valency dictionary. 1

German Compounds in Transformer Models
Neumannová, Kristýna ; Bojar, Ondřej (advisor) ; Zeman, Daniel (referee)
German is known for its highly productive word formation processes, particularly in the area of compounding and derivation. In this thesis, we focus on German nominal compounds and their representation in machine translation (MT) outputs. Despite their importance in German text, commonly used metrics for MT evaluation, such as BLEU, do not adequately capture the usage of compounds. The aim of this thesis was to investigate the generation of German compounds in Transformer models and to explore the conditions that lead to their production. Our analysis revealed that MT systems tend to produce fewer compounds than humans. However, we found that due to the highly productive nature of German compounds, it is not feasible to identify them based on a fixed list. Therefore, we manually identified novel compounds, and even then, human translations still contained more compounds than MT systems. We trained our own Transformer model for English-German translation and conducted experiments to examine various factors that influence the production of compounds, in- cluding word segmentation and the frequency of compounds in the training data. Addi- tionally, we explored the use of forced decoding and the impact of providing the model with the first words of a sentence during translation. Our findings highlight the...

Vetný slovosled v maltčine: Kvantitatívna analýza
Čéplö, Slavomír ; Zemánek, Petr (advisor) ; Fabri, Raymond (referee) ; Zeman, Daniel (referee)
This dissertation is a quantitative analysis of constituent order (i.e. the order of subject, verb and object) in contemporary (post-2000) Maltese, a Semitic language descended from North African varieties of Arabic, spoken primarily in the Malta archipelago and Australia. The analysis is based on data collected in two corpora: a general corpus and a syntactically annotated corpus (dependency treebank); the compilation and descrip- tion of the treebank is the secondary aim of this work. The dissertation comprises 8 chapters divided into two parts: the irst three chap- tersofwhichprovideaconceptualfoundation(chapter1),areviewofexistingmajorap- proaches to the study of constituent order (chapter 2) and a review of previous works on Maltese constituent order (chapter 3). Using these as the background, chapter 4 then sets the research questions and methodology. The remaining three chapters form the core of the dissertation: chapter 5 describes the composition and enrichment of the general corpus of Maltese. Chapter 6 then provides a thorough description of the Maltese treebank and the annotation decisions, thus in effect assembling a sketch of Maltese syntax. Chapter 7 then provides the actual quantitative analysis of constituent order in Maltese based on the treebank, arriving at the conclusion that...

Empirical Models for an Indic Language Continuum
Bafna, Niyati ; Žabokrtský, Zdeněk (advisor) ; Zeman, Daniel (referee)
Empirical Models for an Indic Language Continuum Niyati Bafna July 20, 2022 Many Indic languages and dialects of the so-called "Hindi Belt" and surrounding re- gions in the Indian subcontinent, spoken by more than 100 million people, are severely under-resourced and under-researched in NLP, individually and as a dialect continuum. We first collect monolingual data for 26 Indic languages and dialects, 16 of which were previously zero-resource, and perform exploratory character, lexical and subword cross- lingual alignment experiments for the first time on this linguistic system. We present a novel method for unsupervised cognate/borrowing identification from monolingual cor- pora designed for low and extremely low resource scenarios, based on combining noisy se- mantic signals from joint bilingual spaces with orthographic cues modelling sound change; to the best of our knowledge, this is the first work to do so, especially in a (truly) low- resource setup. We create bilingual evaluation lexicons against Hindi for 20 of the lan- guages, and show that our method outperforms both traditional orthography baselines as well as EM-style learnt edit distance matrices, showing that even noisy bilingual em- beddings can act as good guides for this task. We release our crawled data in a new collection called...

Analysis of valid moves in Scrabble
Dančejová, Katarína ; Zeman, Daniel (advisor) ; Mareček, David (referee)
The bachelor thesis aims to create a program for the analysis of moves in Scrabble. The language dictionary is stored as a GADDAG structure, which enables fast searching of the words of the dictionary. The heuristics for the middlegame and the endgame are applied. These heuristics' goal is to reach the best score at the end of the game, so they also consider the strategic aspects of a position. Thus the program can be helpful even for advanced players. The simulations are made to compare the artificial intelligence using heuristics against artificial intelligence not using heuristics. Artificial intelligence with heuristics has significantly better performance in the games, whether it was starting or not. We create a graphical user interface that recommends the best moves based on the provingly effective heuristics. 1

Computer and internet crimes
Zeman, Daniel ; Gřivna, Tomáš (advisor) ; Herczeg, Jiří (referee)
in English In my thesis I have tried to analyze questions connected to information in general, as in my opinion the most valuable articles of our days. Information society, of which we are part of, is surrounded with information and has developed certain mechanisms, procedures and technology. My aim has been to consecrate a usage of information and communications technology. We can say that nowadays advanced world is almost perfectly linked and networked. It is done by virtue of increasing availability of computers and other communication instruments; another reason is constantly escalating technological ingenuity of their interconnection. Crucial role in this matter plays Internet, the net of nets, offering still faster, cheaper and more variable connection of its segments. It enables receiving and providing for information without any territorial, contentual, quantity limitation. Technological progression, which information sector shows, is unusually dynamic and also blond our control. Advances of the development go hand in hand with its disadvantages, to be specific with exploitation of computers and Internet. The question therefore is, if the proportion of benefits information and communications technology and its misuse stays the same and only the quantity extent rises. The answer is...
