Abstract:
The aim of this thesis is to investigate the tensor decomposition of structured tensors related to SL(n)-irreducible representations. Structured tensors are multilinear objects satisfying specific symmetry relations and their decompositions are of great interest in the applications. In this thesis we look for the decompositions of tensors belonging to irreducible representations of SL(n) into sum of elementary objects associated to points of SL(n)-rational hoogeneous varieties. This family includes Veronese varieties (symmetric tensors), Grassmann varieties (skew-symmetric tensors), and flag v

Abstract:
The aim of this essay is to gain knowledge about attitudes towards the use of different varieties of English in the classroom from the perspective of seven English teachers in Swedish upper secondary school. The study was carried out through interviews with teachers from different upper secondary schools in Sweden. Qualitative interviews were used to gain information from the teachers. The results showed that the language varieties most of the teachers used were American English and British English, which had to do with what variety they were more exposed to.

According to data from the U.S. Census Bureau (2012), the United States is the world's fifth most populous Spanish-speaking country, with over 35 million Spanish-speakers. In addition, Spanish is the most widely taught foreign language in the United States, with more students enrolled in Spanish at the higher-education level than in all other modern languages combined, as detailed in a 2010 report from the Modern Language Association (MLA). How are these two realities connected? Is the United States' status as a top Spanish-speaking country reflected in Spanish as a Foreign Language (SFL) and

Le premier enjeu étant de prouver que les locuteurs du wu produisent effectivement une réalisation voisée en fonction de la position de la consonne et du registre tonal dans un contexte particulier.

Abstract:
Temat gabinetów osobliwości jak dotąd cieszył się zainteresowaniem przede wszystkim badaczy kultury i literatury renesansu, zwłaszcza historyków sztuki zajmujących się dziejami kolekcjonerstwa europejskiego. Jest to zrozumiałe o tyle, że epoka kultury ciekawości była czasem, w którym powstawały pierwsze wunderkamery erudytów. W pracy przyjmuję założenie, że w XIX wieku, a zwłaszcza w jego drugiej połowie, zaistniały warunki do ponownego rozwoju tej formy ekspozycji, która ze sfery arystokratycznych kolekcji przeniosła się przede wszystkim do kultury popularnej i literatury.
