1. The use of determiners in English historical texts: example of the book Postwar: A history of Europe since 1945Karmen Milošič, 2013, diplomsko delo Opis: The theoretical part of the thesis is based on Biber's Grammar of spoken and written English (1999), and Blaganje's Modern English Grammar (2005). I examined all types of determiners which can function as a modifier in a nominal phrase. So, the focus was on articles, possessive determiners, demonstrative determines, quantifiers, numerals, semi-determiners and wh-determiners. In theoretical part I presented the use of these determiners across different registers (prose, academic literature, fiction, news).
The main purpose of the empirical part was an analysis of nominal phrases in order to get data about the use of determiners in English historical texts. The analysis was based on a passage consisting of 5 pages from Tony Judt's Postwar: A history of Europe Since 1945 (2005). In the analysis I focused on those nominal phrases which functioned in a sentence as a subject or an object.
An analysis of the selected passage of the historical text gave the following results.
The most headwords in a nominal phrase are premodified by an article, adjective or some other noun on noun phrase, while the most common postmodifier is a prepositional phrase. Among articles, the most frequently used is the definite article. The most frequent use of the zero article is with unique reference, of the definite article with cataphoric and of indefinite article with specific reference. Possessive determiners are, as is typical for academic writing, quite rarely used in the analyzed passage. More frequent are those with non-human reference (its, their). Also the use of demonstrative determiners is in the analyzed passage consistend with the use of demonstrative determiners in academic prose in general. In my analysis I found only a few quantifiers functioning as a determiner in a nominal phrase. The quantifier both is the most frequently used quantifier. Surprisingly, there are only four examples of numerals in the selected historical text as a part of a nominal phrase. But my assumption that there will be more examples of cardinals than ordinals was correct. Semi-determiners are very rare, I found only two examples of the semi-determiner other as a premodifier in a nominal phrase. There are no examples of such, which is otherwise the most frequent semi-determiner in academic prose. There were no cases wh-determiners as a part of a nominal phrase found in the analyzed passage. Wh- determiners are used only as a part of a postmodifying structure in a relative clause.
The research was carried out manually, while the statistical results are shown in graphs made by the computer. The methods used in thesis are the descriptive method and causal non-experimenting method.

4. Paths through inverse limitsIztok Banič, Matevž Črepnjak, Matej Merhar, Uroš Milutinović, 2011, izvirni znanstveni članek Opis: In Banič, Črepnjak, Merhar and Milutinović (2010) [2] the authors proved that if a sequence of graphs of surjective upper semi-continuous set-valued functions ▫$f_n : X to 2^X$▫ converges to the graph of a continuous single-valued function ▫$f : X to X$▫, then the sequence of corresponding inverse limits obtained from ▫$f_n$▫ converges to the inverse limit obtained from ▫$f$▫. In this paper a more general result is presented in which surjectivity of ▫$f_n$▫ is not required. The result is also generalized to the case of inverse sequences with non-constant sequences of bonding maps. Finally, these new theorems are applied to inverse limits with tent maps. Among other applications, it is shown that the inverse limits appearing in the Ingram conjecture (with a point added) form an arc.

5. Two constructions of continua: inverse limits and compactificationsTina Sovič, 2013, doktorska disertacija Opis: In the thesis we talk about two different constructions of continua. First we present the generalized inverse limits, with help of which we construct Wazewski's universal dendrite. What follows is a description of the compactifications of a ray and the presentation of results about their span.
The first chapter will be an introduction to the continuum theory trough interesting examples, as sin(1/x)-continuum, Hilbert cube, Brouwer-Janiszewski-Knaster continuum and pseudoarc. We will present some of their properties, among which irreducibility, smoothness and span zero are the most important ones for us.
In the continuation we intend to present some various constructions of continua. The main focus will be on the generalized inverse limits and compactifications of rays, which will also be a central part of the thesis. In this chapter, we also study inverse limits in the category of compact Hausdorff spaces with upper semi-continuous functions. We show that the inverse limits with upper semi-continuous bonding functions, together with the projections are weak inverse limits in this category.
The following two are the most important chapters in the thesis. The first is a detailed description of a construction of the family of upper semi-continuous functions f, such that the inverse limit of the inverse sequence of unit intervals and f, as the only bonding function, is homeomorphic to Wazewski's universal dendrite for each of it. Among other results we will also give a complete characterization of comb-functions, for which the inverse limits of the type described above are dendrites.
The next important chapter will be about compactifications of rays. In the first part of this chapter we will use compactifications to prove that for each continuum Y there is an irreducible smooth continuum that contains a topological copy of Y. The second part presents the main results of this chapter; i.e. the span of a compactification of a ray with a remainder that has a span zero is also zero. In the proofs of this chapter we will help ourselves with a discretization of span.

6. Relations between median graphs, semi-median graphs and partial cubesWilfried Imrich, Sandi Klavžar, Henry Martyn Mulder, Riste Škrekovski, 1998 Opis: Podan je samostojen dokaz ekspanzijskega izreka za semi-medianske grafe. Dokazano je, da te grafe lahko karakteriziramo kot tlakovane delne kocke in da za njih velja neenakost ▫$2n-m-k le 2$▫. Pri tem je ▫$k$▫ število ekvivalenčnih razredov relacije ▫$Theta$▫. Za medianske grafe dokažemo, da se dajo karakterizirati kot semi-medianski grafi brez ▫$Q_3^-$▫. Vpeljemo tudi koncept šibke 2-konveksnosti in jo uporabimo, med drugim, za dokaz, da so medianski grafi dvodelni grafi, ki zadoščajo šibki 2-konveksnosti intervalov in štirikotniški lastnosti.

8. Leak-before-break analysis of a pressurizer - estimation of the elastic-plastic semi-elliptical through-wall crack opening displacementNenad Gubeljak, Jožef Predan, Dražan Kozak, 2012, objavljeni znanstveni prispevek na konferenci Opis: The work presents methods to estimate elastic-plastic semi-elliptical through-wall Crack Opening Displacement (COD) for the Leak-Before-Break analysis of a pressurizer. Usually proposed methods are based on GE/EPRI approach or on the reference stress and J-integral as stress intensity factor (SIF) along the crack tip. J-integral calculation provides the value of SIF ateach node of mesh along the crack tip, where values vary from the surface to middle section of material in respect to material properties. COD value is calculated through thickness along the centre of crack. The COD values are less sensitive to distance from crack tip and material properties. The engineering approach for the calculation of J-integral by using COD values and material full stress-strain data is given. COD values are proportional to surface length of semi-elliptical through wall crack of the pressurizer Ključne besede: mehanika loma, semi-elliptical through-wall crack, crack opening displacement, GE/EPRI approach, leak-before-break analysis, reference stress approach Objavljeno: 10.07.2015; Ogledov: 467; Prenosov: 23 Povezava na celotno besedilo |
