V zaključni nalogi magistrskega izobraževanja so predstavljeni ključni gradniki in tehnologije za prenos signalov radijskih postaj do končnih uporabnikov. Bistvo naloge so radijske komunikacije, ki omogočajo prenos prizemnih radijskih signalov preko radijskega omrežja do končnih uporabnikov. Uporabniki radijskih sprejemnikov danes za sprejem radijskih postaj še vedno najpogosteje uporabljajo analogne sprejemnike s frekvenčno modulacijo (angl. Frequency Modulation – FM). Analogna FM radiodifuzija se bo v prihodnje začela opuščati, kot se je že pred desetletji začela opuščati radiodifuzija na osnovi analogne amplitudne modulacije (angl. Amplitude Modulation – AM). Razvila pa se je napredna digitalna zvočna distribucija (angl. Digital Audio Broadcasting Plus – DAB+), ki se začenja z vklopom radijskih postaj v omrežja pogosteje uporabljati. Sodobnejša tehnologija prinaša boljšo kakovost zvoka ter dostop do želenih informacij ob poslušanju izbrane radijske postaje. Ker se tehnologija DAB+ postopoma uvaja, je namen te zaključne naloge preveriti vso zbrano teorijo. Zbrani viri opisujejo prenos signalov preko oddajnikov do končnega uporabnika. Že od leta 2016, ko je v Sloveniji začelo oddajati prvo omrežje T-DAB+, sledim vklopu radijskih programov v omrežja in oddajnikov za širjenje omrežja. V tem času sem podrobneje raziskal tehnologijo z meritvami sprejetih radijskih signalov, s tem pa sem pridobil nova znanja, ki sem jih podal v zaključnem delu. Ker se o naprednejši tehnologiji ne ve veliko, sem se odločil, da bom bodočim uporabnikom predstavil to tehnologijo. Prehod z analognega na digitalni radio je počasnejši, kot je bil prehod z analogne na digitalno televizijo. Žal se o konkretnih vklopih radijskih programov v omrežja ne obvešča veliko, saj nekatere radijske postaje, ki že oddajajo v omrežjih, ne obveščajo poslušalcev o tem. Iz tega razloga želim v nalogi prikazati primere sprejema radijskih signalov z različnimi sprejemniki in antenami ter kakšne prednosti prinaša tehnologija T-DAB+. S tem si bodo uporabniki lažje predstavljali, v kakšnih okoliščinah lahko prihaja do prekinitev radijskega signala in novosti, ki jih bodo lahko prebrali na radijskih sprejemnikih, saj jih ob uporabi starejše tehnologije do zdaj niso mogli. Cilj naloge je predstaviti tehnologijo bodočim uporabnikom s preverbo teorije, zbrane z različnih virov. Z meritvami sprejetih signalov želim raziskati ali teorija, ki opisuje prenos signalov od oddajnikov do sprejemnikov drži. This master's thesis presents the key building blocks and technologies for the transmission of radio signals to end users. The thesis focuses on radio communications that enable the transmission of terrestrial radio signals over a radio network to end users. Currently, users of radio receivers primarily use analog receivers with Frequency Modulation (FM) for the reception of radio signals. However, analog FM broadcasting will start to phase out in the future, just as analog Amplitude Modulation (AM) broadcasting started to phase out decades ago. On the other hand, Digital Audio Broadcasting Plus (DAB+) has been developed and is increasingly being used as radio stations integrate into networks. This newer and advanced technology offers improved sound quality and access to the desired information when listening to chosen radio stations. As DAB+ technology is gradually being implemented, the purpose of this thesis is to test the gathered theory. The collected sources describe the transmission of signals via transmitters to the end user. Since 2016, when the first T-DAB+ network started broadcasting in Slovenia, I have been monitoring the inclusion of radio programs in the networks and the use of transmitters to expand the network. During this time, I have delved into this technology in greater detail by measuring received radio signals, which has provided me with new knowledge that I present in this thesis. Due to the limited information available about the more advanced technology, I have decided to introduce this technology to future users. The transition from analog to digital radio is slower compared to the transition from analog to digital television. Unfortunately, there is not much information available about the actual inclusion of radio programs in the networks, as some radio stations that are already broadcasting on the networks do not inform listeners about this. Consequently, in this thesis, I aim to provide examples of radio reception using different receivers and antennas, and to highlight the advantages of T-DAB+ technology. This will help users understand the circumstances in which radio signal interruptions can occur and the new features they will be able to access on their radios, which were not possible with older technology. The main objective of this thesis is to introduce the technology to future users by testing the theory gathered from various sources. By measuring the received signals, I intend to investigate whether the theory describing the transmission of signals from transmitters to receivers is accurate.

Title: Reliability of the GPS system in measuring key parameters of external load in youth soccer players Objectives: The main objective of this study was to investigate reliability of a GPS system in measuring key parameters of external load in youth soccer players Methods: The research group consisted of 15 youth football players aged 15 - 18. They were U16 and U19 players from elite youth teams playing the highest competitions in their category. Players undergone field trials under the supervision of qualified professionals, which were running under the standard conditions described within the methology section of the theses. To determine the reliability of the GPS system, we used the Catapult Playertek system, where the player wore 3 trackers and performer various speed test field, on the football pitch on artificial grass of the third generation. Results: The results of the work provide information that, in terms of statistical significance, eighteen of the nineteen parameters are significant. In terms of substantive significance, 3 parameters have poor reliability - maximal acceleration and distances in acceleration zones 1 - 2 m·s−2 and 2 - 3 m·s−2 . 7 parameters have moderate reliability - distances in deceleration zones 1 - 2 m·s−2 , 2 - 3 m·s−2 , 3 - 4 m·s−2 and > 4 m·s−2 , distances in...

Title: Comparison of the frequency of individual game activities with the rule allowing one-stroke and multi-stroke dribble in minihandball matches Objectives: The main objective of this paper is to determine which type of dribbling, single- strike dribbling or multi-strike dribbling is more effective for the game of minihandball. Methods: For the preparation of the bachelor thesis, a handball tournament was organized for three Prague handball teams of mini pupils. Within the framework of the conducted tournament, the game activities of the individual and the dribbling methods were observed. The indirect observation method was used to obtain data from video recordings taken during the tournament, which were subsequently processed in Microsoft Excel. Results: From the records obtained, it can be concluded that dribbling does not have a significant effect on the game of mini-betting. Both types of dribbling bring some positives and negatives to the game. Keywords: handball, minihandball, individual game activity, dribble, frequency

Abstact Title: Incidence of injuries in the Czech athletics national team Objectives: The aim of this diploma thesis is to determine the frequency and location of injuries in athletes of the Czech national team, whether their injuries recur and, if so, the types of injuries that recur more often. I also examine how and how often their recovery takes place. Also whether the frequency of visits to individual procedures within the annual training cycle changes. Methods: We performed an exploratory method using a questionnaire survey. The questionnaire has open, closed and semi-open questions. Then we evaluated the results of the questionnaires from the respondents using a quantitative approach. Results: We recorded the most common injuries occurring in athletes. The most common injuries in athletes are hamstring tearing, stretching or tearing of the Achilles tendon, ankle sprain and stress fracture. Keywords: athletics, Czech national team, injuries, regeneration methods

Na základě dat z žákovského korpusu češtiny CzeSL-SGT a jejich srovnání s korpusy rodilých mluvčích (SYN2020, SKRIPT 2012) jsou zachycena specifika užití obsahových vět se spojkami že, aby, ať, jestli, zda, zdali a -li v jazyce nerodilých mluvčích, s přihlédnutím k jejich jazykovým skupinám (indoevropské, neindoevropské a slovanské jazyky). Analýza se zaměřuje na typické kolokace, jejich nadužívání či podužívání v žákovském jazyce a popis jazykových jevů, jež se odlišují od úzu rodilých mluvčích. Data ukazují, že nerodilí mluvčí mají tendenci nadužívat významově obecné a jim dobře známé jazykové prostředky na úkor sémanticky specifičtějších lexikálních jednotek. Rozdíly mezi žákovským jazykem a územ rodilých mluvčích jsou zřejmé u kolokací, různých slovesných vazeb a napříč jazykovými skupinami. Popis žákovského jazyka má význam pro výuku češtiny jako L2, neboť umožňuje lépe didakticky zpracovat zkoumané jazykové jevy, podporovat jejich aktivní užívání a odstraňování typických chyb, a to i s ohledem na konkrétní jazykovou skupinu. Based on data from the Czech learner corpus CzeSL-SGT and a comparison with native speaker corpora (SYN2020, SKRIPT2012), the paper accounts for the specific use of content clauses with the conjunctions že, aby, ať, jestli, zda, zdali and -li in the language of non-native speakers, taking into consideration their language group (non-Indo-European, Indo-European and Slavonic languages). The article analyzes typical collocations, their over- and underuse by learners; it also describes language phenomena that differ from native usage. The data show that non-native speakers tend to overuse semantically broad lexical items, which they are familiar with, at the expense of more specific ones. The differences between learner and native usage are apparent in collocations, different types of verb complements and across language groups. The description of learners’ languages is helpful in teaching L2 Czech, since it facilitates a better didactic approach to specific language phenomena, promoting their active usage and the correction of typical errors with respect to particular language groups.

Bakalaura darbā tiek aplūkota muzikālās skaņas iespējamā ietekme uz cilvēku atkarībā no frekvenču un skaņas spiediena līmeņa atšķirībām, un, izmantojot frekvencionālo analīzi, no vides zinātnes skatu punkta tiek pētīta robeža starp troksni un mūziku. Darba teorētiskajā daļā tiek apskatīti ar akustisko vidi saistītie jēdzieni, kā arī tiek izpētīta skaņas nozīme un skaņas ietekme uz cilvēku. Darba praktiskajā daļā tiek aprēķināts dažādu mūzikas instrumentu (taustiņinstrumentu, stīgas instrumentu, pūšaminstrumentu un sitaminstrumentu) radītais skaņas spiediena līmenis, atkarībā no kura tiek noteiktas mūzikas instrumentu dominējošās frekvences un to atšķirības starp mūzikas instrumentu grupām. Mūzikas instrumentu radītais skaņas spiediena līmenis tiek koriģēts saskaņā ar A mērījumu skalas koeficientiem (standartizēta metode skaņas līmeņa tuvināšanai cilvēka dzirdes uztverei) un tiek salīdzināts ar trokšņa līmeni, lai noteiktu tā iespējamo negatīvo ietekmi. Bakalaura darba rezultāti parāda, ka nav iespējams stingri nodalīt trokšņa piesārņojuma un mūzikas darbu robežas, ņemot vērā cilvēku subjektīvās uztveres īpatnības un akustiskās vides apstākļus/skaņas apstākļus; no vides zinātnes viedokļa, izmantojot frekvencionālo analīzi, ir iespējams izpētīt tikai mākslas darba (mūzikas kompozīcijas) fizisko-akustisko aspektu, savukārt, piemēram, subjektīvi-psiholoģiskais aspekts ir maz pieskarts., The bachelor’s thesis views the possible influence of musical sound on a person depending on differences in frequencies and sound pressure levels, and explores the boundary between noise and music by means of frequency analysis from the point of view of natural sciences. The theoretical part of the work is aimed at studying the concepts related to the acoustic environment as well as the analysis of the importance of sound for a person and the influence on them. The practical part of the work focuses on the calculation of the sound level produced by various musical instruments (keyboards, strings, wind instruments, and percussion), their dominant frequencies are determined depending on the sound pressure level, and the differences between the groups of musical instruments are revealed. The sound pressure level generated by musical instruments is measured with an A-weighting filter (a standardized method of approximating the sound level to human hearing perception) and compared with the noise level to determine its possible negative impact. The research results show that it is impossible to set strict boundaries between noise pollution and a musical work considering the peculiarities of the subjective perception of people and the conditions (circumstances) of the sound. From the point of view of environmental science, it is possible to use frequency analysis to study the physical and acoustic aspect of a work of art (musical compositions) only, while, for example, the subjective and psychological aspect remains little discussed.

Eutypella parasitica R.W. Davidson and R.C. Lorenz is the causative agent of Eutypella canker of maple, a destructive disease of maples in Europe and North America. The fungus E. parasitica infects the trunk through a branch stub or bark wound. Because the fungal community may have an impact on infection and colonization by E. parasitica, the composition of fungi colonizing wood of dead branches of sycamore maple (Acer pseudoplatanus L.) was investigated in five sampling sites in Slovenia. Forty samples from each sampling site were collected between the November 2017 and March 2018 period. Isolations were made from the wood in the outer part of dead branches and from discoloured wood in the trunk that originated from a dead branch. Pure cultures were divided into morphotypes, and one representative culture per morphotype was selected for further molecular identification. From a total of 2700 cultured subsamples, 1744 fungal cultures were obtained, which were grouped into 212 morphotypes. The investigated samples were colonized by a broad spectrum of fungi. The most frequently isolated species were Eutypa maura (Fr.) Sacc., Eutypa sp. Tul. and C. Tul., Fusarium avenaceum (Fr.) Sacc., Neocucurbitaria acerina Wanas., Camporesi, E.B.G. Jones and K.D. Hyde and E. parasitica. In this study, we distinguished species diversity and the fungal community. There were no significant differences in the diversity of fungal species between the five sampling sites, and branch thickness did not prove to be a statistically significant factor in fungal species diversity. Nevertheless, relatively low Jaccard similarity index values suggested possible differences in the fungal communities from different sampling sites. This was confirmed by an analysis of similarities, which showed that the isolated fungal community distinctly differed between the five sampling sites and between the different isolation sources. Eutypella parasitica was isolated from all five investigated sampling sites, although Eutypella cankers were observed in only three sampling sites, indicating the possibility of asymptomatic infection.

Breathing is essential part of our life. Breathing exercise can help acquirement of proper breathing. Thanks to this process, sports performance can be improved. The aim of our work is to determine differences in values and compare results of spiroergometric parameters from testing on a bicycle ergometer in the laboratory of functional load diagnostics. We obtained the results by an entrance test and a final test tested after eight weeks. Between testing, selected individuals performed a respiratory intervention program. Nine performance university athletes, especially focused on football, got involved in our research. Data at the rest position and load were crucial. We focused on dynamic ventilation parameters such as tidal volume, respiratory rate, minute ventilation or oxygen consumption. In the output test, we also recorded changes in values in the respiratory segments, abdominal, thoracic and subclavian areas. We verified the results from the point of view of material and statistical significances. Both of these significances were evaluated in this thesis. The materially and statistically significant differences in the results of measurement were improved in the oxygen consumption by our probands. The studied probands were able to improve in various phases of load, for example, the material significance was detected at the respiratory rate during the load of three watts per kilogram. Ascertained results were not improved in all monitored parameters. The most significant changes were discovered in the three-watt load during the respiratory rate from 32,8 +- 7,2 to 30,9 +- 5,1 breaths per minute. Probands reduced oxygen consumption by 14.8 percent.

Proces obdelave z abrazivnim vodnim curkom (AVC) spada med konturne postopke rezanja, pri katerem visokohitrostnemu vodnemu curku dodajamo abrazivna zrna. Voda skupaj z abrazivom udarja ob obdelovanec, pri čemer odnaša material. Rezalni postopek je primeren za obdelavo različnih materialov, med drugim kovin, kamna, stekla in organskih materialov, brez prisotnosti toplotno vplivanega območja. Kljub dobrim lastnostim postopka obdelave največjo slabost predstavlja manjša natančnost rezanja. Ena izmed tipičnih značilnosti obdelave pri rezanju z AVC je nastanek brazdavosti površine. V delu smo opravili pregled literature v povezavi z značilnimi pojavi na površini materiala po rezanju z AVC. V eksperimentalnem delu naloge smo na obdelovani stroj za rezanje z AVC namestili dozirni sistem z vrtečim se kolesom, ki dovaja abraziv v mešalno komoro rezalne glave ter z njim opravili graviranje materiala. Z namenom iskanja morebitnih povezav za nastanek brazdavosti na površini obdelovanca smo v aluminijevo zlitino in konstrukcijsko pločevino naredili gravure globin do nekaj milimetrov, pri čemer smo globino reza povečevali s spreminjanjem nastavitvenih parametrov obdelave. Z digitalnim mikroskopom smo analizirali topografijo površin gravur ter z obdelavo podatkov rezultate ovrednotili. Rezultate smo prikazali s pomočjo grafov moči spektralne gostote. Ugotovili smo, da moč spektralne gostote narašča pri določenih frekvencah, ki so posledica večanja globine reza. The abrasive water jet cutting process (AWJ) is one of the contour cutting processes in which abrasive grains are added to the high-speed water jet. Water, along with the abrasive, hits the workpiece, which removes material. The cutting process is suitable for the treatment of various materials, including metals, stone, glass and organic materials, without the presence of a heat-affected area. Despite the good features of the machining process, the greatest disadvantage is the lower cutting accuracy. One of the typical features of machining when cutting with AWJ is the stria formation. In this work we have reviewed the literature in relation to the characteristic phenomena on the surface of the material after cutting with AWJ. In the experimental part of the work, an abrasive dosing system with a rotating wheel was installed on the AWJ cutting machine, which feeds the abrasive into the mixing chamber of the cutting head. With mentioned dosing system we engraved the material. In order to find possible connections for the formation of stria on the surface of the workpiece, we made engravings of depths of up to several millimeters in aluminium alloy and structural steel, increasing the cutting depth by changing the machining parameters. Using digital microscope, we analyzed the topography of the engraving surfaces and evaluated the results by processing the data. The results were plotted using spectral density power graphs. We find that the power of the spectral density increases at certain frequencies, which is the result of increasing the depth of the cut.

Rezanje z abrazivnim vodnim curkom (AVC) je vsestransko uporabljen postopek konturnega rezanja. Visok tlak pospeši vodni curek skozi ozko šobo, kjer mu primešamo abrazivna zrna. Zaradi visoke hitrosti in masnega doprinosa abrazivnih delcev dobimo curek z visoko kinetično energijo, kar odnaša material obdelovanca. Pri rezanju smo omejeni z debelino obdelovanca, ki je odvisna od moči samega curka. Za ta postopek je značilen pojav valovitosti, zlasti v spodnjem delu reza, ki je nezaželen, saj nam kvari geometrijo obdelovanca. V delu smo pregledali literaturo, povezano z značilnimi pojavi na površini obdelovancev po rezanju z AVC. V eksperimentalnem delu smo preučili vpliv masnega pretoka abraziva in podajalne hitrosti na značilnosti dobljene površine po graviranju z AVC ter iskali povezavo z nastajanjem valovitosti reza. Poskuse smo opravili na aluminijevi zlitini 5083. Globine gravur smo omejili na maksimalno 3 mm, kjer smo si pomagali z Zengovo enačbo za izračun teoretičnih globin reza. Eksponente te enačbe smo uspešno prilagodili in dosegli natančnejše napovedovanje globine graviranja. Rezultate smo vrednotili s pomočjo grafov močnostnega spektra, ter ugotovili, da se za izbrane parametre v razponu podajanja od 500 do 900 mm/min ter masnega pretoka od 12 do 48 g/min, nastanek valovitosti še ne pokaže. Abrasive water jet cutting (AWJ) is a versatile contour cutting process. High pressure accelerates the water jet through a narrow nozzle, where it is mixed with abrasive grains. Due to the high velocity and mass contribution of the abrasive particles, a high-kinetic energy jet is obtained, which erodes workpiece material. When cutting, we are limited by the thickness of the workpiece, which depends on the power of the jet itself. This process is characterized by an occurrence of waveform, especially in the lower part of the cut, which is undesirable, since it negatively impacts on the geometry of the workpiece. We reviewed literature related to the typical phenomena on the surface of the workpieces after cutting with the AWJ. In the experimental part we studied the influence of the abrasive mass flow rate and the feed speed rate on the characteristics of the surface after engraving with the AWJ and sought a connection with the formation of the waviness. Experiments were done on aluminum alloy 5083. The depth of the engraving was limited to a maximum of 3 mm, the Zeng's equation was used to calculate the theoretical depths of the cut. The exponents of this equation were successfully adapted and more precise forecast of the depth for the engraving was achived. The results were evaluated using graphs of the power spectrum. It has been found that for the selected parameters in the feed speed range from 500 to 900 mm/min and mass flow rate from 12 to 48 g/min, there is no formation of waviness yet.

The goal of the bachelor thesis: "Lexical stress variability in English" is to describe basic principles of stress assignment in English with a focus on lexical units that have more realisations of stress placement without changing the meaning of the word. The practical part concentrates on collecting lexical items with variable stress. There is going to be an alphabetical list of stress-divergent words along with phonetic transcription of stress variations at the end of the work.

The thesis presents a network model, where financial institutions form linkages at various investment horizons through their interdependence measured by volatility connectedness. Applying the novel framework of frequency connectedness mea- sures Baruník & Křehlík (2018), based on spectral representation of variance de- composition, we show fundamental properties of connectedness that originate in heterogeneous frequency responses to shocks. The newly proposed network mod- els characterize financial connections and systemic risk at the short-, medium- and long-term frequency. The empirical focus of this thesis is on the interde- pendence structure of US financial system, specifically, major U.S. banks in the period 2000 - 2016. In the light of frequency volatility connectedness measures, we argue that stocks with high levels of long-term connectedness represent greater systemic risk, because they are subject to persistent shocks transmitted for longer periods. When we assess institutions' risk premiums in asset pricing model, the model confirms the significance of volatility connectedness factor for asset prices.

Commodity Connectedness: Short-run Versus Long-run Vojtěch Jurka Bachelor Thesis, IES FSV UK, 2018 The thesis contributes to empirical literature that studies volatility spillovers among the commodity and equity market, focusing on short-term and long-term linkages between them. Studying the persistence of volatility transmission is helpful for understanding the information flow, which is crucial for risk management and regulators. The persistence of volatility linkages represents how quickly information can be processed by markets. In this work, we explain the theoretical background of connectedness measures proposed by Diebold and Yilmaz (2012) and show the relationship with measures defined in the frequency domain by Baruník and Křehlík (2018), that allows us to distinguish between short and long persistent shocks in volatility of markets. We continue with the analysis of volatility transmission among stock market and key commodities which represents various sectors of the commodity market. Our first key finding is that in the period 1993- 2015 spillovers among markets more than doubled and persistence of connections have increased. Using a rolling sample over 250 days, we evaluate rich dynamics of connections between equity and commodity sectors. The dynamic analysis reveals that the global financial...

The thesis aims for relationship between military-caused disturbance intensity and species richness, conservation value and composition of arthropods communities in the Brdy Mts. In the Brdy abandoned military area (MTA), a highly heterogeneous habitat mosaic developed by the long-term influence of military disturbances on two shooting areas of Jordán and Tok. The habitats range from strongly disturbed sites with sparse vegetation, through heterogeneous growths of Erica and Vaccinium in moderately disturbed sites, to sparse woodlands in the least disturbed sites. Based on the shooting areas history reconstruction, 24 study plots of 4 categories of different disturbance intensity were selected in both shooting areas together. Standardized sampling of seven groups of arthropods was performed in summer 2017 by pitfall traps, yellow pan traps, and light traps. More intensive disturbances positively influenced species richness of Aculeates and conservation value of spiders and beetles, but negatively affected species richness of moths. Simultaneously, the intensity of disturbances affected community composition of spiders, moths, beetles, Aculeates and Orthopteroids. Endangered species mostly affiliated to the more intensively disturbed plots. This results should be helpful in understanding of influence...

The present thesis compares the use of result/inference discourse connectives in two corpora compiled by the author. The student corpus consists of 43 literary essays by Czech university students of English and American studies and the reference corpus contains 34 journal articles written by native expert writers. The main objective of the thesis was to determine to what extent students resemble professional writers in their use of result/inference connectives with respect to the frequency, position and scope of the connectives. The thesis revealed a strong overall overuse of result/inference connectives by students as well as overuse and underuse of individual connectives. It was also found that both types of writers generally prefer initial to non-initial placement of result/inference connectives; however, students more frequently use the connectives with the immediate scope.

The work concerns the study of limited collocational paradigms in modern German. It is based on the corpus cooccurrence analysis and aims at the clearing up of the phenomenon of the so- called monocollocability. After the undertaken analyses and reflections there came a conclusion that corroborated the original point of view, namely, that the so-called monocollocability presents a multiplex phenomenon, where a metaphore of centre and periphery seems to be appropriate. In the analyses there occur semantically neutral word, inherently bound on certain collocated for formal reasons.

Title of thesis: Clinical Effectiveness of the Schultz Autogenic Training on the Electrical Activity of the Brain Objectives: The thesis aims to analyze the impact of Schultz autogenic training on brain activity evaluated using EEG Course of action: To obtain the data, an experimental group containing 11 participants aged 20-30, disregarding gender, was created. Participants practiced Schultz autogenic training using the identical audio record once a day during the course of nine weeks. Upon completion of the training, all participants were subjected to one-off measurement by the Nicolet EEG instrument. Brain activity was measured before, during and after the training. Obtained EEG data were processed with NeuroGuide software using coherence analysis and fast Fourier transform. Coherence analysis provided charts mapping the electrical activity of Brodmann areas during the course of all three stages and fast Fourier transform yielded data of performance ratio between theta and alpha frequencies, so called T/A index.

1 Abstract The purpose of this bachelor thesis is to find out, if the regular conjugation in preterite and the regular forming of past participle, or the absence of alternation of e and i in the 2nd and 3rd person singular, present tense indicative and in imperative singular concerning the most frequent irregular verbs have already reached the written standard German (in the informal spoken language they in some measure occur). In the first part (theoretical) the thesis explains some terms of language change, comments on the traditional classification of the irregular German verbs on the basis of ablaut and offers a more suitable one according to Bittner, sums up the main points from the codification literature. In the second part (empirical) a list of eleven irregular verbs is made (using W Corpus of the Institute for German Language in Mannheim), which are to be examined, a methodology is developed to detect the typing errors occurring in the found forms, and the eleven verbs are empirically researched. The conclusion presents the results and answers the main questions put in the introduction.

The work is divided into two parts - theoretical (Chapter 1) and practical (Chapter 3 - 6). The theoretical part explores methamphetamine - what is it, history, effects, number of users. The second part consists of interviews with eight users of methamphetamine. The author demonstrates common habits of methamphetamine users. It is very difficult, because there are many factors affecting frequency and dose of users. Many of that factors are not entirely predictable. Keywords methamphetamine, drug, dose, frequency, combination

The present thesis examines the influence of Czech nouns frequency features on their acquisition by non-native speakers. The first theoretical part summarizes the ongoing discussion regarding the importance of frequency for the entrenchment of grammatical categories in one's mind as outlined by cognitive and psycho-linguists abroad. The second introduces the research methodology, collection method and annotation of 20 lemmas obtained from non-native Czech speaker corpus CzeSL-SGT. Subsequently, an analysis of selected nouns is carried out with regard to their grammatical profiles (comprising two or three most frequent case forms as found in SYN2015). Based on its results, the production of non-native speakers shows a tendency to follow grammatical profiles as demonstrated by high correspondence of frequency features of nouns on the one hand and by low error rate in morphology of most frequent forms on the other. Additionally, cases where lower rate does not correspond to the above mentioned model can be explained using type frequency, i.e. the productivity of particular declension models having simultaneously more far-reaching effect, and higher relevance of nominative as the default form for non-native speakers.

Mūsdienās internets ir kļuvis par neatņemamu daļu cilvēkā dzīvē, tāpēc arī ir kļuvusi lasīšana tiešsaistē. Tā rezultātā cilvēki apstrādā daudz informācijas tīmeklī, ikdienā lasot blogus, komentārus par sociālo mediju, avīžu rakstiem vai ziņām uz dažādām tēmām, tostarp politikā, ekonomikā, sociālajos jaunumos, medicīnā, izklaidēs, sportā, biznesā un citām tēmām. Teorētiskie rezultāti liecina, ka pastāv atšķirības starp amerikāņu angļu un britu angļu valodas variācijām, piemēram, gramatikā, vārdu krājumā un pareizrakstībā. Kā arī teorētiskā daļa ietver diskusiju par tīmekļa krājumu. Frekvenču analīze un kvalitatīvā analīze tika izmantota kā galvenās izpētes metodes. Empīriskā daļa koncentrējas uz nepieciešamu datu iegūšanu un sniedz autora pētījumu analīzi. Šī pētījuma rezultāti liecina, ka britu angļu un amerikāņu angļu vārdi tiek izmantoti amerikāņu un angļu laikrakstos tiešsaistē., Nowadays the internet has become an integral part of people life, so has become reading online. As a result lots of information on the web by daily reading of blogs, posts on social media, newspaper articles or news about different topics, including politics, economics, social news, health, entertainment, sports, business and other topics. The theoretical results indicate that there exist differences between American English and British English language varieties, for example in grammar, vocabulary and spelling. As well the theoretical part comprises the discussion on the web as a corpus. Frequency analysis and qualitative analysis was applied as the main research method. The empirical part focuses on obtaining the necessary data and presents the analysis of the author’s research. The results of this research prove that the British English and American English words are used in the American and English online newspapers.

The theme of this thesis is the analysis of transport connection of rural municipalities (villages) in South Moravian Region. In the theoretical part by means of literature search terms regarding transport and transport services are defined. Then the description of transport types according to the covered territory and characteristics of the Integrated Transport System of South Moravian Region (IDS JMK) follow. After that the transport and socio-economic characteristics of South Moravian Region are also described. In the practical part the situational analysis of the transport connection of municipalities in South Moravian Region on weekdays and at weekends is carried on. It is evaluated on the basis of three parameters: frequency, time and price. The transport service was learned in the groups of municipalities according to the population in the direction to the catchment area centre of individual districts and to the capital of South Moravian Region - Brno. The practical part is closed with the analysis of alternative personal transport (time and price of travel) with different number of passengers and the possibility of cycling for three selected micro-regions.

1 Abstract The dissertation Theoretical tools for categorization and functional explanations of relations in language is focused on linguistic categorization from the perspective of empirical gram- matical research. The primary aim is to present the theoretical and practical potential for the investigation of grammatical categories, stressing functional explanations of why cer- tain language structures are the way they are. The text is divided into two parts. (i) The first two chapters are devoted to the theoretical and methodological foundations of empirical linguistic research (including issues of metalanguage, language comparison, discreteness and gradience). Particular emphasis is placed on functional-evolutionary approaches, which describe grammar in interconnection with language use, and more specifically on func- tional explanations by means of frequency. (ii) In the following three chapters, the potential of corpus-based research is demonstrated in accordance with the principles adopted in (i). It is applied to the linguistic categories of possession and adjective comparison in Czech. Possession in Czech is described with regard to hypotheses based on statistical tendencies in language use. The main results of the research revealed the relationship between frequency of use and the animacy hierarchy,...

The thesis will deal with the frequency analysis of handshapes and types of signs in the Czech sign language. The analysis will be based on authentic communications of the Czech deaf with different characteristics (signers of different sex, age, education etc.) as well as communications representing the influence of different objective factors, viz. private vs. public communications, monologues vs. dialogues etc. The results of the frequency analysis will be compared both to analogous results of research in other sign languages, such as American, Australian and British, and to the results of frequency analysis of passive handshapes, or unmarked handshapes in the Czech sign language.

Title: Quality of Performance in Shooting Sports related to Heart Frequency Objectives: The aim of this thesis was to determine the influence of heart frequency on the quality of performance in shooting sports. To compare the control group with the experimental group on the basis of results. Methods: The method for obtaining data was the measurement of heart frequency by means of Polar sporttesters. Processing of obtained results by means of the program Polar ProTrainer 5. Tables and all statistical calculations were carried out by means of adequate functions of the program Microsoft Excel 2010. Results: Results of the thesis pointed out that the heart frequency did not have any influence on the quality of shooting performance of the tested shooter. These results also proved that shooters from the control group were better than shooters from the experimental group. Keywords: quality, performance, shooting, heart, frequency

This paper presents results of natural frequency analysis of the 3D numerical model of transformer. The goal is to map structural dynamics and vibrations of its selected parts with respect of the mechanical resonance. The model taking into account the real arrangement of the transformer core with winding is solved numerically by the finite element method.
