Relation between optical and microscopic properties of hydrogenated silicon thin films with integrated germanium and tin nanoparticles
Stuchlík, Jiří ; Stuchlíková, The-Ha ; Čermák, Jan ; Kupčík, Jaroslav ; Fajgar, R. ; Remeš, Zdeněk
The hydrogenated amorphous silicon layers (a-Si:H) were deposited by PECVD method on quartz substrates. During interruption of PECVD process the vacuum chamber was pumped up to 10-5 Pa and 1 nm thin films of Germanium or Tin were evaporated on the surface. The materials form isolated nanoparticles (NPs) on the a-Si:H surface. Then the deposited NPs were covered and stabilized by a-Si:H layer by PECVD. Those two deposition processes were alternated 5 times. The a-Si:H thin films with integrated Ge or Sn NPs were characterized optically by PDS and CPM methods, and microscopically by SEM and AFM microscopies. Optical and microscopic properties of the structures are correlated and discussed considering their application in photovoltaics.\n

Formal distinction between comitative and instrumental in contemporary Swedish
Čermák, Jan ; Zíková, Magdalena (advisor) ; Láznička, Michal (referee)
The aim of this bachelor thesis is to identify the degree of differentiation between the comitative and instrumental constructions in collocation with specific verbs in contemporary Swedish. Swedish marks both meanings syn cretically using the preposition med ("with"). There is a tendency to reinforce the comitative reading by adding the adverb tillsammans mea-ning "together", resulting in the construction tillsammans med ("together with"). The method of Distinctive Collexeme Analysis will be applied to a set of 200 verbs that collocate with both variants of the prepositional phrase, having them either as their arguments or as adjuncts. For each combination of a verb and a preposition, 50 complements of the preposi-tion with the highest tf-idf score (term frequency-inverse document frequency) will be selected and marked for animacy. The data comes from 146 Swedish corpora of various genres within Språkbanken. Relevant factors will be both the semantics of the verb and the animacy of the no-minal complement of med. It is assumed that some verbs with particular semantic features tend to prefer one prepositional phrase over the other. Should the tendency for the comitative meaning to be reinforced by ad-ding tillsammans be strong, that would point to a proces of grammaticali-zation in progress. Powered by...
Prosodic Phrasing in Good Speakers in English and Czech
Hledíková, Hana ; Skarnitzl, Radek (advisor) ; Čermák, Jan (referee)
The aim of this BA thesis was to compare prosodic phrasing in good public speakers of English and Czech. Naive observations of English and Czech spoken in everyday communication suggest that Czech intonation is more flat and that Czech speakers divide the flow of speech into longer prosodic phrases than English speakers. We focused on the speech of good public speakers to see whether there are differences in the temporal and melodic characteristics between the two languages in this stylistic domain. We analysed segments from speeches by 10 TEDTalk speakers in Czech and American English and measured the length of prosodic phrases, speaking rate, standard deviation of the fundamental frequency in each prosodic phrase and in the nuclear part of the phrase (measure of pitch span), and Cumulative Slope Index in each prosodic phrase (measure of melodic variability). The number of syllables per prosodic phrase was found to be higher in Czech than in English, although phrases were generally very short in both languages. Speaking rate was found to be faster in Czech than in English. Pitch span in both the whole prosodic phrase and the nuclear part of the phrase was found to be wider in English than in Czech. Melodic variability was found to be higher in English than Czech. These results show that there are...
Loss of Inflections in Updated Old English: the Noun Phrase in the Text of Nativitas Sanctae Mariae
Malcová, Markéta ; Čermák, Jan (advisor) ; Tichý, Ondřej (referee)
This work is concerned with the question of loss of inflections in the noun phrases of the Ælfrician homily De nativitate Sanctae Mariae (Nativitas Sanctae Mariae Virginis; Pseudo- Matthaei Evangelium). On the basis of collation of the manuscripts MS Hatton 114 and Bodley 343 a qualitative and quantitative analysis of the noun phrase is performed. The analysis aims to describe the main tendencies in the phonetic and morphological changes found in the text. The main tendencies of the morphological changes point toward the approach chosen by the scribe of the Updated manuscript Bodley 343 in dealing with the weakening case system. This includes unifying nouns which vary in gender affiliation in a single paradigm or the gradual implementation of new word endings with more narrowly defined meanings than ever before. The observed changes are placed in the context of the development from Old to Middle English.
Infinitival complements of the verb help in present-day spoken British English
Průšová, Karolína ; Malá, Markéta (advisor) ; Čermák, Jan (referee)
The thesis investigates the use of the bare infinitive and to-infinitive as a complement of the verb help in present-day spoken British English. It focuses on the frequency of each form of the infinitive and on factors influencing the choice between them. Material for the analysis is extracted from the corpus Spoken BNC2014. The theoretical part defines the infinitive, describes its forms and functions, and introduces different approaches to infinitival complements of help together with the studies concerned with them. The analysis consists of two parts. In the quantitative part the frequency of the construction ‚help + (NP) + bare infinitive' and ‚help + (NP) + to-infinitive' is determined. The qualitative part analyses these constructions in terms of factors influencing the choice of the infinitive form after help, as they were described in secondary literature. Except for the factors adopted from secondary literature, attention is paid to other features connected to the individual constructions. key words: complementation of the verb help, bare infinitive, to-infinitive, factors influencing the choice of the infinitive form, present-day spoken British English
As in the Middle English Romance Sir Gawain and the Green Knight
Novotná, Alena ; Čermák, Jan (advisor) ; Tichý, Ondřej (referee)
This diploma thesis aims to classify the uses of as in the text of the Middle English romance Sir Gawain and the Green Knight from a formal and functional perspective. As has acquired a great number of functions through the process of grammaticalization. The theoretical part of the thesis firstly deals with the historical development of as from the Old English swā and ealswā. It then describes the uses of as in Middle English. In this period, as was found to function as an adverb, conjunction, preposition and a relative pronoun. Each of these uses can be further divided into a number of subtypes. The thesis subsequently summarizes the functions as can have in Present-Day English. The final sections of the theoretical overview briefly present the processes of grammaticalization and constructionalization, as these two processes have been instrumental in the development of as. The practical section is concerned with the analysis of all the instances of as in the chosen text. It classifies them and defines each type of use in more detail. The analysis also considers competing means of expressing the same function and comments on possible ambiguities. Furthermore, this section deals with the uses of as in the text from the perspective of their grammaticalization and also points out uses which are only...
