Mirativity in Spanish (with Reference to Czech)
Kverková, Venuše ; Čermák, Petr (advisor) ; Smažíková, Adéla (referee)
in English Mirativity in Spanish (with Reference to Czech) This diploma thesis deals with mirativity in Spanish and Czech. The aim of this thesis is to introduce the category of mirativity and analyze its lexical, morphological and syntactic means of expression. In the first part, we use secondary literature to define key concepts such as mirativity, evidentiality and modality and we compare their similarities and differences. In addition, we discuss whether mirativity constitutes an independent language category, and we present various perspectives from other authors. In the second part, we analyze Spanish and Czech lexical, morphological and syntactic mirative feaures and we briefly mention suprasegmental and extralinguistic elements of mirativity. For these purposes, we use language corpora (InterCorp, CORPES XXI, syn2020 and Araneum Bohemicum Maximum) and literature related to the topic. We also take into consideration the broad context. The outcome of this work is a complex typology of mirative features in Spanish and Czech. Keywords: mirativity, mirative, evidential, Spanish, Czech
The Expression of Warning, Threat and Menace in Spanish and Czech
Demartini, Matyáš ; Čermák, Petr (advisor) ; Smažíková, Adéla (referee)
This paper presents a linguistic analysis of the expression of warning, threat and menace in Spanish and Czech. The thesis examines the communicative strate- gies employed by speakers to influence the behaviour of addressees and highlights the differences between the literal meaning of words and their intended impact. The theoretical framework of the paper is based on the concept of speech acts and their influence on addressees. The analysis employs a corpus-based ap- proach to examine the linguistic expressions of warning, threat and menace in Spanish and compares them with Czech counterparts. This methodology allows the theoretical concepts to be tested by examining the actual use of (literary) language. Although both languages have a wide range of systemic possibilities of expression, the thesis identifies subtle differences in the way these functions are linguistically realised. This illustrates that the pragmatic meaning of an utterance is not constrained by specific linguistic forms and depends largely on the overall context. Keywords: warning, threat, menace, speech acts, pragmatics, Spanish, Czech
Expressing iteration in contemporary Spanish
Hašková, Alena ; Čermák, Petr (advisor) ; Rubešová, Štěpánka (referee)
The aim of this paper is to introduce means of expressing iteration in contemporary Spanish and the ways of translation into Czech. The theoretical part defines the basic terms, presents the issue of category of aspect in Spanish and in Czech. It also presents the division of this category in these languages, as well as according to semantic meanings and formal means. Special attention is paid to the terms of iteration and reiteration and their ways of expression, namely suffixes re-, sub-, and sobre-; verbal periphrases volver a + infinitive, venir + gerund and tener + participle; and lexical-syntactic means de nuevo, por segunda vez and otra vez. The practical part contains three case studies, divided according to the mentioned formal means of expression. For the analyses are used two corpus - Araneum and InterCorp. The Araneum corpus serves to verify the general frequency of the phenomena in Spanish and to assess whether there is a binding effect for the given means. Corpus InterCorp is used to compile a typology of Czech equivalents.
Clause negation in Spanish and in Catalan
Kolář, Luboš ; Čermák, Petr (advisor) ; Rubešová, Štěpánka (referee)
(in English) The topic of this thesis is the clause negation in Spanish and in Catalan. Our aim is to compare the functioning of this phenomenon in both systems. To this end, we have used the negational typology of the Discourse Functional Grammar at the theoretical level, and then, at the practical level, linguistic corpora, in particular InterCorp, Araneum Hispanicum Maius and Corpes XXI. The analyses showed differences in the functioning of clause negation, especially from a morphosyntactic point of view. Functional differences were also revealed. The analyses also showed a diaphasic variation in Catalan in terms of the formal means of expressing clause negation. Key words: negation, Spanish, Catalan, corpus, syntax
Analysis of the Josephson junction phase dynamics with machine learning techniques
Jurčík, Róbert ; Žonda, Martin (advisor) ; Čermák, Petr (referee)
In this master's thesis, we provide a brief introduction to Josephson junctions and machine learning algorithms. We analyze the phase dynamics of Josephson junctions, notable for their significant second harmonic in the current-phase relationship. Initially, we generate data by simulating stochastic dynamics. We then investigate two aspects: determining occupation probabilities from the distribution function and detecting and categorizing anomalies (phase jumps) in a velocity spectrum. We determine that the random forest algorithm is the most effective model for calculating occupation probabilities from distribution functions. Anomaly detection is achieved without the need for machine learning, thanks to effective preprocessing of the velocity evolution. We then analyze two characteristics of detected anomalies: the number of maxima which they cross and the initial and final positions of the particle with respect to two minima in a potential. For determining each characteristic, we employ supervised learning, requiring only one hidden layer with 32 neurons. 1 April 27, 2024 1 Introduction 2
Causativity in Contemporary Portuguese
Laufková, Petra ; Čermák, Petr (advisor) ; Svobodová, Iva (referee) ; Svobodová, Petra (referee)
Univerzita Karlova Filozofická fakulta Ústav románských studií Románské jazyky Abstrakt disertační práce Mgr. et Mgr. Petra Laufková KAUZATIVITA V SOUČASNÉ PORTUGALŠTINĚ Causativity in Contemporary Portuguese Vedoucí práce: prof. PhDr. Petr Čermák, PhD. 2023 Abstract Causation is one of the basic aspects of the way we conceive coherence in the world we live in. Ways of expressing causativity in languages has therefore been at the center of scientific attention for many years. Causative structures involve two events: a causing event expressing that an entity, the causer, acts on another entity, the causee, and causes its change or activity coded as a second event. On the one hand, our work is a structured compilation of theories and data provided by other scientists, bringing to light different causative mechanisms, their formal description, data related to their distribution and mainly their semantic explanation, based on cognitive linguistics. On the other hand, we carry out research to support theoretical assertions with quantified data and find new results. Contemporary Portuguese has a wide range of morphological, lexical and syntactic causative tools. This thesis describes all of them. Nevertheless, we are mainly interested in what distinguishes Portuguese from other languages we know: the fact that...
Welding problems of the „press chamber“ component
Čermák, Petr ; Dohnal, Ivo (referee) ; Kubíček, Jaroslav (advisor)
Petr Čermák: Welding problems of the "press chamber" component The goal of this work is to produce the "press chamber" component of a food industry machine and selection of a suitable arc welding method, a base and a filler material. Practical part of this work includes technological design of a weldment production process considering all the know-how concerning welding technology, heating process of a stainless steel and a weld quality testing. Especial emphasis is put on analyzing of deformations and residual stresses during welding and taking countermeasures to reduce these undesired defects in the "press chamber" weldment made of high alloy austenitic steel. The final output is the "press chamber" component and a welding jig design reducing occurrence of the undesired deformations or residual stresses.
Using program Rosetta to estimate of soil moisture retention curves from experimental size Bohaté Málkovice
Čermák, Petr ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Hydraulic characteristics are the most important properties of soil, i.e. retention curve of soil moisture and hydraulic conductivity. Hydraulic conductivity of soil characterizes the ability of the soil to conduct water. Retention curve expresses the relationship between moisture and moisture potential of soil. The running of retention curve is influenced by many factors, eg. grain size and mineralogical composition, content of humus, reduce bulk density and structure of soil. Measurement of retention curves takes a lot of time and money in laboratory conditions therefore pedotransfer functions seem to be an alternative solution. The thesis aims to estimate moisture retention curves of soil in a selected area of interest in South Moravia using program Rosetta (Schaap, 2003). Data of granularity (% content of clay, sand and dust), bulk density of soil and hydrolimits field water capacity and wilting point were used as predictors in individual models of program Rosetta. Data of grain were matched by FAO / USDA system. Retention curves of soil moisture were measured on a sand tank and overpressure devices. The measured retention curves were parameterized by RETC program. Estimated retention curves were graphically compared with measured to determine the quality of the estimate. The accuracy of the estimate was assessed by correlation coefficient R of determination coefficient R2 and standard error SMRE. Usability own derivatives pedotransfer functions is hard to say due to the size of the input data file. I would recommend further verification of data at the other localities in south Moravia.

Čermák, Petr ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Petr Čermák: Service time assessment of the welded frame for the hydraulics of RONDOPRESS press machine The goal of this thesis is to assess durability of the welded frame for the hydraulics of RONDOPRESS press machine, which is used at the bakery sector in the food industry. The press machine chamber is made of stainless steel, because of food (dough) processing. But the strengthened part of the press machine consists of a carbon steel frame with a hydraulic cylinder. For the life of the RONDOPRESS machine is determining the rigidity and durability of the frame. Therefore it is necessary to carry out a study of carbon steel weldability, choose a suitable welding method and then make an evaluation of welded frame construction used in terms of weld joints in analyzed areas. Practical part consists of the frame computer model design, stress calculations and the service time calculation for required 1,825,000 cycles, choosing the appropriate welding method and avoiding undesired deformations. The final output is an operational frame of the RONDOPRESS press machine that meets the required service time specified by the number of production process cycles.
Digital conversion of analog signals
Čermák, Petr ; Sedláček, Jiří (referee) ; Murina, Milan (advisor)
My work is focused on digital elaboration of the analog signal. In my work the analysis has been carried out in all parts of digit chains processing analog signal. The entranced variable is signal from measuring coil, which is afterwards strengthen and transfer to a sampler. The sample signal is processed by an A/D converter and then sends to a parallel port. On the basis of acquired data the scheme has been constructed for sample processing. The transfer to the parallel port is done (made) in two steps, at first one part of the word is transferred and then the rest of the word follows. Between the converter and sampler is tight relationship and synchronization. Both of them are managed from one central bus.
