During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas. Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.

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.

The general pension supplement introduced in 1960 which introduced the public pension funds in Sweden. In the late 1990s the Swedish pension system was reformed and established the current structure. Today, funds are one of the most common forms of savings in Sweden and mutual funds are the most common type.The purpose of this study is to analyze the risk-adjusted returns for the AP funds in the period 2003-2009. Study was based on five funds that are most similar and have the same mission. These funds are AP1, AP2, AP3, AP4 and AP7.The method used in this study is mainly based on a survey of the figures and measurable units of statistical methods that have been carried out by a quantitative approach.

The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.

The aim of this masters thesis is to examine query expansion. Query expansion is the process of adding new terms to a query to improve the retrieval effectiveness. In this study the baseline query was expanded in five different modes. The first expansion strategy was formulated by the inflected terms as the system does not allow truncation, I have inflected the terms, e. g.

The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout. The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.

This essay aims to examine and compare the attitudes of decision makers in the local government and representatives of pensioners in two different geographic areas. The main questions were:- their attitudes towards the "stay home principle" (kvarboendeprincipen, a principle that aims to make it possible for people with a handicap, disease or age to stay in their homes instead of moving to nursing homes).- their attitudes towards nursing homes for old people- their attitudes towards the possibility of staying at home when you are old and handicapped and in need of care.The essay is built on qualitative research methods, based on interviews and on a review of research in the field.The author found a complex picture of attitudes. Everybody thinks that the best is to live in your own home as long as possible, except from those who live with Alzheimer´s disease. They showed different opinions on the issue of the need for moving to nursing homes. This might result in forcing people to stay at home.

This paper analyses how Swedish fine-art oil paintings sold at auctions has performed as a monetary investment during the period autumn 1985 until spring 2006. An average price technique as well as a hedonic regression technique, applied to a sample of 19 213 auction sales, is used to construct price indices. The indices show somewhat different results, which is explained by the inability of the average price model to adjust for relative differences in quality between periods. The hedonic regression model on the other hand captures this effect, why the hedonic index is applied in a financial return model. By adjusting for transaction cost, the financial return of an average investment in paintings is calculated.

The Voices of ParliamentCongruence between party and personThe purpose of this study is to determine the congruence between the opinions of members of parliament and their respective party policies, in order to further determine the cause of poor voter-party congruence and whether or not the individualization of the parliament could affect the character of legislation. To do so, the study asks two primary research questions;- "Are the communicated party policies representative of the opinions of the members of parliament?"- "Is the discrepancy between party policies and the opinions of the members of parliament sufficient for the individualization of parliament to substantially affect the parliament's decisions?"The study answers these questions by comparing the average of self-described left-right stances of members of parliament with the average of voter-described left-right stances of party policies, using existing survey data and a constructed left-right dimension. The lower average is then subtracted from the higher average, creating a value of congruence that is then inserted into a constructed congruence dimension. The primary findings of the study suggest that there is substantial congruence between party policies and the opinions of the members of parliament, and that the discrepancy between them is unlikely to substantially affect the parliament's decisions..

In the media richness of everyday life, the encounter with information graphics ishappening on a daily basis, whether we are aware or not. With the development andeasy access of technologies, new ways to create and display information graphics hasemerged. Among them, the animated information graphics, which in the few pastyears appears to have increased in popularity on video sharing websites such asVimeo and Youtube. In the genre of animated information graphics, there seems to bean inherent diversity regarding the design characteristics. In this study we exploredliterature and research on information graphics and related subjects.

The aim of this thesis is to study and analyze a village in the southern of Sweden called Gnosjö, which is famous for a special spirit of industrial success and entrepreneurship. Gnosjö has been successful and famous for many years but is now standing in front of several threats, like a growing number of out moving inhabitants, a low standard of education and difficulties for women to make carrier. Trying to reduce the threat of young inhabitants moving out, a new education program started three years ago with the purpose to make young students to be more interested in the technical development of the industry and make them stay in the district and hopefully be entrepreneurs.The research questions are; which consequences does ?Entekprogrammet? and the background of the students have on the students view on the spirit of Gnosjö, carrier in the local industries and wish of staying or moving from Gnosjö. Furthermore, I want to see if there are any differences between the girls and the boys, does sex have an influence on the view at the future? The study is made by qualitative and quantitative method.

The purpose of this study is to investigate childrens possibilities to retrieve information by searching in searching engines designed for children. Two such search engines are examined: Yahooligans and Kids Click, both of which index pages in English only. I have compared Yahooligans with its equivalence for adults; Yahoo, by evaluating the retrieval effectiveness. Some functions in Kids Click and in Yahooligan are investigated. Seven class room studies are described in the prior research chapter.

This essay investigates whether there?s logic behind the sanction system regarding the penalty imprisonment in the swedish penal code. The focus is in general on crimes against the person and crimes against the state, but in particular on crimes of serious fiscal offence and crimes of serious assault. The idea with the essay was also to explain the wording purpose behind the punishment ranges in these selected crimes. The essays focus is on the public unawareness on how the punishment ranges is used.

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.
