The aim of this master ´s thesis is to understand why there are difficulties in finding joint methods and standards in the field of image indexing. The main focus for interpreting these issues is on Sara Shatford ´s article Analyzing the Subject of a Picture: A Theoretical Approach. In the article Shatford discusses a theoretical basis for identifying and classifying the subject in a picture. In doing so she uses concepts taken from The Philosophy of Art, Meaning in Language and Visual Perception. With the aid of S.R.

This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.

Bakgrund: Globalt sett är HIV/AIDS en utbredd sjukdom som orsakar stora påfrestningar på varje individ som drabbas. HIV/AIDS har blivit vår tids mest stigmatiserande sjukdom då den är kopplad till starka tabun. Syfte: Att beskriva sjukvårdspersonalens stigmatisering och diskriminering av patienter med HIV/AIDS utifrån ett patientperspektiv. Metod: Systematisk litteraturstudie där sökningar utfördes i Cinahl, Pubmed, PsycInfo, Science Citation Index Expanded samt SveMed+. Sökningarna resulterade i 11 kvalitativa och tre kvantitativa artiklar relevanta för syftet.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Effekterna av psykoterapi har visat sig positiva i en mängd olika studier. Syftet med föreliggande studie var att undersöka potentiella prediktorer för terapeutisk framgång bland psykoterapipatienter från den svenska psykiatriska öppenvården. Patienter kategoriserades till tre olika utfallsgrupper kliniskt signifikant förbättring, reliabel förbättring, och svarade inte på behandling genom att använda Reliable Change Index och GSI av SCL-90 som kriterievariabel. Grupperna jämfördes med hänsyn till patienternas självskattningar, terapeuternas bedömningar, terapeutvariabler, och enhetskarakteristika. Variabler som visade på signifikanta skillnader mellan grupperna inkluderades i en multipel diskriminantanalys.

Bakgrund Oväntad död är en traumatisk upplevelse förnärstående, kris och sorg i någon form är ofrånkomligt isamband med död och saknad. Vårdpersonal står inför en svårutmaning i omvårdnaden för att ge ett kompetentomhändertagande. Det korta mötet mellan vårdpersonal ochnärstående har visat sig vara av betydelse. Syfte Syftet medlitteraturstudien var att belysa närståendes behov ochvårdpersonals uppfattningar om närståendes behov i sambandmed en oväntad död. Metod Metoden var en litteraturstudie därdet ingick både kvalitativa och kvantitativa artiklar.

The UN was established after the Second World War. The organization?s primary goal was to maintain peace among all nations. When the UN intervenes in other states affairs, it is violat-ing the principles it is set to defend, principles of non-intervention and respect for sover-eignty. The outcome from such interventions is very important, a result that can legitimize the action.

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

The aim of this study was to describe the prevalence of gingivitis, periodontitis and dental caries in individuals with type 2 ? diabetes. The study was conducted in a form of a general literature review with the restricted to the following conditions: human studies, English, and articles published between 2007 - 2012. Articles lacking a control group were excluded. The data were collected through searches of the medical database PubMed. A compilation of 11 scientific articles was examined.

The purpose of this essay is to study causes for the lack of political trust in Europe and especially in Sweden. The essay starts with a presentation of two theories about the reasons for low political trust. Robert D. Putnam among others presents a theory that gives social capital an important role when viewing the low political trust. As Putnam sees it a person that participates in any kind of organization, political or not, develop trust for other human beings that in the long run affects political trust.

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

Due to the growing wild boar (Sus scrofa L.) population in Sweden there has been an increase in wild boar related traffic accidents, damage on cropland, and conflicts regarding the management of the wild boar. Knowing what makes the wild boar reproduce and survive more or less successfully in different geographic areas is an important part of managing the population. According to previous studies the wild boars rate of increase varies from county to county. The aim of this study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase.

Young people?s political influence has been surveyed, studied and discussed several times in Sweden during the last decade. There is a fear among the politicians that the young people are not interested in politics, especially not in party politics. On the other hand there is, among the youngsters a feeling of invisibility, not being seen or heard or for that sake respected. There are a lot of formal possibilities for young people?s political influence, but there are not as many real possibilities or situations to actually practice these possibilities.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

This thesis analyzes and discusses the role of institutions concerning countries' abilities to create economic wealth. The countries that we are analyzing are the former members of the Warsaw pact and former Yugoslavia. These countries are referred to as transition countries. In order to analyze the transition countries institutional structure we are using Douglass C. North's theory regarding institutions and institutional building.
