Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
Det växer inget träd i öknen! : En kvalitativ studie om de preventiva insatserna mot ungdomskriminalitet inom stadsdelsområdet Angered i Göteborg.
Juvenile criminality has been widely discussed in the public debate. But what is there to do about a phenomenon like juvenile criminality in Sweden. Many studies have shown the potential of lowering juvenile criminality if different actors would collaborate. This research aims to explore preventive work and cooperation between different actors working with youth in risk of crime in Angered, with a focus on Hjällbo and Hammarkullen.

?När högskolan kom till byn..? Folkbibliotekets roll vid högskolestudier på distans.
The purpose of this Master's thesis is to investigate the role of the public library when the local government in the municipality arranges distance education at university level. The thesis has two main areas of questioning and these are goals and resources. In the study it is examined if the local goals have changed during the period 2000 until 2005, due to the development of distance education. It is investigated if change actually has occurred and if it has, in what way the goals have changed. It is also examined if and how the goals correspond with the work that is being performed in the public library.
Behöver tillväxten en stad? Om Dublin som politisk arena, aktör och tillväxtmotor
This thesis intends to examine the role of the city, Dublin, in the Irish economic growth during the 1990s. It is a case study where Dublin is compared with current theories on post modern cities as growth machines and increasingly prominent actors in the global context. The study has an interdisciplinary approach but focuses on political science issues such as power distribution, global-local governance and local political organisation. It is a theory driven study that also intends to add aspects to the understanding of the cities of our time. I argue that Dublin has faced a lot of changes during the last decades in accordance with the post modern city.
Regionala strategier på lokal nivå Om kulturarv- och kulturmiljöarbete i regionalt och kommunalt utvecklings- och tillväxtarbete
The following essay aims at the interplay between regional och municipal growth work, and theway cultural heritage is used in growth work strategies. The main issue has been whether theregional strategies are followed up in the municipal strategies, which has been investigated bymeans of question which impact the region?s strategies has at the local level.The essay draws upon an instrumental perspective on cultural heritage and cultural environment,here defined as instruments in the national development and growth efforts. Three publicationsthat highlights potential roles of cultural heritage and cultural environment to act as instrumentsin the regional and municipal development and growth efforts has thereby been selected astheoretical models. These roles has further been summarized in a tabular form as a schematicdivision of main themes with sub-categories, used as a framework for deciphering the regionaland municipal strategies.A content analysis of available strategies at both regional and local levels have been used as amethod for investigating the issue, where the role of cultural heritage and cultural environment(as defined in the schematic table) has guided the reading.
Folkbibliotek och resursfördelning. En jämförande studie av sju folkbibliotek i Uppsala kommun.
Allocation of funds to public libraries is uneven and this study will try to explain the reasons and clarify why the allocations of funds are distributed like they are and what calculations influenced the financial apportionment. This master thesis accounts for allocation in seven public libraries in Uppsala. The study shows that one reason for uneven allocations is demographic. Another reason is that the library has come into a good or bad circle. There are no models for allocation of funds to public libraries in Uppsala, thats why their allocations are given after a percentage increase of earlier years allocations, and that leads to a good or bad circle.

Utvärdering av två hullbedömningssystem för katt av en djursjukskötarstudent och djurägare
Obesity is a growing global health problem among both humans and cats with the risk of several medical conditions as a result. This can be detected and prevented by body condition assessment methods in order to visualize and detect possible or potential weight problems in cats.To achieve the best results, owner and cat should be introduced to this as soon as possible in their contact with veterinary care.Purina Body Condition System and Walthams Feline Body Mass Index are both morphometric assessment methods that are quick, relatively cheap and simple to perform. 20 cats with owners and a veterinary nurse student participated in a study to compare pet owners and a veterinary nurse student's assessment of the Purina Body Condition System and WALTHAM's Feline Body Mass Index. The body condition assessment methods were compared with each other, and it was investigated which method was preferred, the body condition distribution among the studied cats and if long-haired cats' body condition was more often misjudged. Results of the study showed a significant difference between pet owners and the veterinary nurse student's assessment of Purina BCS with a difference in median of 1.
Bildförbättring över en bildsekvens
When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
Ett holländskt fenomen i Värmland : Faktorer bakom och effekter av en holländsk inflyttning
AbstractDuring the last five years there has been a considerable immigration from the Netherlands to Värmland in Sweden. INVA, Invest in Värmland, wanted to highlight this phenomenon and therefore contacted Karlstad University to make a survey about how extensive the immigration is and what consequences it brings for the business life and municipalities in Värmland. We were luckily chosen to perform this research and the main focus in this study has been the following questions:? Why do the Dutchmen choose to buy their house in Värmland?? What are the main reasons for leaving the Netherlands?? What consequences does the immigration cause for the business life in Värmland?? How do the Dutchmen experience the contact with Swedish authorities?To answer the questions we designed a questionnaire that was sent to 200 Dutch house purchasers. The ambition was to survey all the Dutch house purchasers in Värmland, but with the time constrains and the municipalities having problem to find complete data, we limited the survey to 200 households.

Näringsbelastning på en anlagd våtmark från åker, skog och enskilda avlopp :
This work is a part of the project ?Våtmarker i odlingslandskapet ? uppföljning av miljömålen? (Wetlands in arable land ? following-up of the environmental goals). The main objective with this project is to study nitrogen and phosphorus retention in a constructed wetland by using mass balance calculations. Continuous measurements of nutrients and water flow through the inlet and the outlet of the wetland are made. However, substantial amounts of nitrogen and phosphorus were assumed to reach the wetland with a drain-pipe transporting wastewater from nearby houses (10 persons).
