Referenser i informationsåtervinning: utvärdering av en sökstrategi för citationsindex

In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.

Att åter fungera som vilken medborgare som helst - om att bli integrerad i samhället efter drogmissbruk

The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.

Klimatsmarta Hyresgäster : Potential hos hyresgästen för minskning av energianvändning i en kontorsbyggnad på ett klimatsmart sätt

The starting point for this master thesis was the product of the company "Humlegården", which allows its tenants in office buildings to follow their electricity consumption in real time, through their Smartphone's. The idea that resulted from that application is to investigate if it is possible to direct the tenants in office buildings to reduce their energy consumptions, but also to be satisfied with the indoor environment. This work addresses the factors which are the main energy consumers in office buildings. It addresses legal requirements and standards which are important to follow in order to achieve good thermal comfort in buildings. Some of them are physical climate factors like thermal environment, air quality and lightning.

Förbrukningsreduktion : Ett alternativ till gasturbiner som snabb aktiv störningsreserv?

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Jämställdhetsutbildning och jämställdhetsarbete bland sjukhuschefer

This paper is about research carried out at a hospital at which managers had taken a course in gender equality. The aim was to get a deepened understanding of them and their work on gender equality. I wanted to find out if they themselves felt that they had obtained any new knowledge and if they had changed anything at their workplace because of this new knowledge. I also wanted to know if they had experienced any problems in this process. I found that the course has been more or less decisive in order for them to start working with questions concerning gender equality.

Varför Storbritannien? : Svenska uppslagsverk och det historiska förklaringsperspektivet (1907-1998)

Title: Why Great Britain? ? Swedish Encyclopaedias and the Explanatory Perspective of History, Essay in History AbstractIn my essay I describe how Swedish 20th century encyclopaedias interpret the coming about of the British Empire, the overall purpose being to establish a pattern of evolution in terms of historical understanding on the part of the encyclopaedic literature. Firstly, I have tried to determine whether the presentations at all constitute explanatory efforts. In those cases where they do, I have sought to ascertain whether the reasons put forward are to be understood as structural and stable, or as matters of less permanence. I have also tried to link these interpretations to significant ?constructions? of history ? i.

Tre studenter med ADHD berättar om upplevelsen av att läsa i högre utbildning

Research shows that there is a lack of knowledge of adult students with ADHD. Most of all research focuses on children with ADHD in school. The purpose of this study was to gain a better understanding of how adult learners with ADHD experience academic studies related to cognitive difficulties, emotion, motivation, and their experience of SOC. The questions tried to determine how any cognitive difficulties and emotions are perceived, how students' motivation to study impacted and their experience of SOC based on studies in higher education. To answer the purpose and questions used qualitative interviews based on three students with ADHD using a hermeneutic method.

Det är värre att inte börja studera än att hoppa av: En fenomenologisk studie om hur icke traditionella studenter upplever studieavhopp från högskoleutbildning

In Sweden we have the highest rate of nontraditional students among Europe. Coincidently, we also have the highest rates of drop outs among OECD. In this particular field, drop out from higher education, there is a need fore more qualitative studies that can support the "statistics". Studies about experiences of drop outs are significant for society, university and individual. The aim of this study is to describe and understand how nontraditional student experiences drop out from higher education.

Funktionsupphandling av solelanläggningar

This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.

Högläsning i förskolan : En undersökning i teori och praktik

Why should teachers devote themselves to reading aloud? Reading aloud has a given place in most of the Swedish preschools. Many teachers read to children. Research on the subject has shown that it is very rewarding for preschoolers to have stories read to them. They hear how the language is constructed, becomes aware of matter of text, and they are able to take part of how other people live.

INDUSTRIALISERING AV FLERBOSTADSHUS

The construction process which is used today while constructing residential buildings has for along time remained unchanged. Unfortunately the development process has gone away frombecoming industrialized and instead most of the work is done at the construction site. In thisrespect this is a worse alternative because the project outcome will be more expensive and theconstruction time will be longer. Skanska?s vision is to have a process which is more like the oneused in small residential buildings which is fully industrialized.The constructing process for residential building involves more parties and therefore it becomesmore complicated.

Metoder för kartläggning och analys av nätförluster i lågspänningsnät

An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.
