Verkligen väldigt mycket förstärkningsord : En studie i ungdomars användning av förstärkningsord / Really very much intensifiers : A study in young adults’ use of intensifiers

Elofsson, Veronica, Utterberg, Josefine January 2010 (has links)
Our exam paper is about young adults’ use of intensifiers in school papers. The theoretical background includes previous research about intensifiers in the Swedish language and above all young adults’ use of intensifiers. We have chosen to focus on all intensifying expressions which young adults’ use, because we did not want to limit our research material. We made a comparing study of 25 student papers from year 1999 and 25 student papers from year 2009 to find similarities and differences. Our result answers our four main questions: “How has the frequency of intensifiers changed from year 1999 to year 2009?”, “Which new intensifiers have been added?”, “In which contexts are intensifiers used?” and “Are there any differences in the use of intensifiers between boys and girls?”. The result shows that the number of intensifiers has increased during the 10 year period but that the selection of used intensifiers has decreased. Furthermore is a change in which intensifiers that are used and in which contexts they are used illustrated. The result also shows that boys in year 1999 use intensifiers more frequently than the girls, but in year 2009 the result was opposite.

The effects of raster structure suppression on visual thresholds, target acquisition performance, and image quality

Beamon, William S. 07 April 2010 (has links)
A television image is formed by a series of parallel luminous lines called a raster. The visual prominence of the raster structure interferes with the extraction of information from the image. The raster may be suppressed experimentally by a deflection process called spot wobble. Experiments were conducted to determine the effects of raster structure suppression on visual sine wave modulation thresholds and dynamic target acquisition performance using normal and noise degraded imagery. Results indicate raster structure suppression and improvements in Sine wave threshold sensitivity are correlated and that a suppressed raster significantly improves target acquisition performance for noise-free conditions. Performance correlations with the modulation transfer function area (MTFA) image quality metric were not as good as were the correlations between observer task performance measures and areas under the threshold functions. A rationale for improving the efficacy of the MTFA image quality metric was postulated. / Ph. D.

L'intensification en anglais : entre grammatical et lexical / Intensification in English : between grammar and lexis

Bordet, Lucile 14 November 2014 (has links)
L’expression de l’« intensification » en anglais a peu été abordée par la communauté linguistique. Les études qui ont été menées se limitent aux adverbes intensifieurs et classent ces derniers parmi les procédés morphosyntaxiques. Il semble toutefois que les adverbes intensifieurs se situent à l’interface du lexical et du grammatical et sont soumis à un renouvellement constant. Ce travail se propose dans un premier temps d’établir une nouvelle typologie des procédés d’intensification en tenant compte des zones de chevauchement qui existent entre les divers procédés. Dans un second temps, le cas particulier des adverbes intensifieurs est abordé à l’aune de la grammaticalisation et de la lexicalisation. Finalement, ce travail conclut par une étude de l’évolution diachronique des adverbes intensifieurs afin de mettre au jour les mécanismes du processus de renouvellement langagier. / The expression of intensification has hardly been tackled by the linguistic community over the years. The research that has been conducted so far is usually restricted to intensifying adverbs, which are generally considered as morphosyntactic processes. Intensifying adverbs, also referred to as “intensifiers”, are submitted to constant renewal. However, intensifiers appear to be at the junction of grammar and lexis. First, a new typology of the processes used to express intensification will be put forward. The fact that the various processes often overlap will be taken into account. The specific case of intensifiers will then be dealt with in the light of grammaticalization and lexicalization, two processes which seem to be at work in the evolution of intensifiers. Lastly, a corpus-based study will look into the diachronic evolution of intensifiers in order to unveil the mechanisms of renewal and language change.

Strategie vyjadřování atenuace a akcentuace ve španělských žurnalistických textech. / Strategy of attenuation and accentuation in Spanish news texts.

PAPEŽOVÁ, Michaela January 2016 (has links)
This graduate thesis is concerned with a comparative analysis of attenuators and intensifiers in Czech and Spanish language. The research has been conducted on Czech and Spanish journalist texts from major newspaper and magazines. The theoretical analysis starts by classifying expressions that are used to intensify or attenuate. The author follows the traditional Spanish classification which has been extended with expressions that she finds important. All expressions are examined from both the grammatical and expressive perspective. The analysis then continues by introducing the types of journalists texts used in the research. The research is based on comparison of attenuators and intensifiers in both languages and their influence on the reader.

No. of bitstreams: 0 / Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) / Tomografia por Coerência Óptica, ou simplesmente OCT (acrônimo do inglês: Optical Coherence Tomography), é uma técnica para geração de imagens de seções transversais de meios espalhadores ao comprimento de onda utilizado. A OCT é baseada em interferometria óptica e gera imagens comumente correlacionadas às imagens geradas exames histológicos com a vantagem de ser indolor, não invasiva e não utilizar radiação ionizante. Este estudo dividiu-se em dois objetivos distintos, um refere-se à aplicação de sinais interferométricos de autocorrelação para a formação de imagens de amostras com estruturas complexas. O segundo objetivo foi o estudo das estruturas denominadas de harmônicos e sua aplicação no aumento da resolução axial de um sistema OCT. Com relação à primeira parte, constatou-se que o sinal interferométrico de autocorrelação é muitas vezes ignorado ou descartado pela OCT tradicional. Análises mais profundas da teoria de interferometria, juntamente com alguns estudos anteriores, apontaram para a possibilidade de gerar imagens de maior complexidade morfológica utilizando o sinal de autocorrelação, com a vantagem de se utilizar um arranjo óptico mais simples e também possibilitar imagens estáticas de amostras em movimento axial. Para testar os benefícios e as limitações da técnica de autocorrelação (Au-OCT) foi montado em laboratório e foram realizadas imagens de amostras no repouso e em movimento e confrontadas com imagens geradas no sistema OCT convencional. O sistema de Au-OCT foi capaz de gerar imagens de estruturas diversas (dentes, filmes plásticos entre outros), e apesar de possuir uma qualidade de imagem inferior à OCT, ela apresentou vantagens quando a amostra sofre deslocamentos axiais. Já em relação as características harmônicas, que se apresentam em amostras de alta refletividade óptica como falsas estruturas em imagens OCT, todo um estudo para o entendimento do fenômeno foi desenvolvido. Demonstrou-se também a possibilidade de utilização dessas estruturas para aprimorar a resolução axial diferencial (entre estruturas da própria amostra) através de um estudo numérico e experimental. Para isso padrões dimensionais do tipo degrau foram mensurados e os resultados tratados de acordo com procedimentos metrológicos, mostrando que os harmônicos podem ser utilizados para promover o aumento de resolução axial de um fator de aproximadamente dois. Por fim uma análise crítica sobre os resultados e uma discussão sobre perspectivas dos temas abordados, foram realizada. / Tese (Doutoramento) / IPEN/T / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP / FAPESP:09/13764-3

Maximizers - completely complex adverbs : A corpus study of the maximizer usage in American and Swedish journalists' writing in English

Eriksson, Sanna January 2014 (has links)
The purpose of this study is to investigate the possible differences in the way American and Swedish journalists writing in English use maximizers, i.e. intensifying adverbs. In order to fulfill the purpose, information about how maximizers are used in two different sub-corpora, namely SWENC (The Swedish-English Corpus) and TIME (Time Corpus of American English) is collected. The data in SWENC has been collected from various websites where the crucial criterion was that the authors of the articles must have Swedish as their first language. The data from TIME has been collected from Time Magazine’s online corpora which is freely available on the Internet. The results show that there are some differences in the way Swedes and Americans use maximizers. The number of tokens for each maximizer does not differ to a great extent between the two corpora. However, there are larger deviances in the use of collocations and semantic prosody. The conclusion drawn from this is that there are indeed some differences in how American and Swedish journalists writing in English use maximizers, although they are not very many.
