The purpose with this project was to invent a product that secures buildings sewersystems against rats. The problem was presented to us by a local building maintainer inHalmstad, who had experienced big problems with rats in his real estate. The project hasbeen carried out by Per Johansson, Robert Lidén and Niclas Nilsson under our ownauspices. We are primarily sponsored by AMLI Business Partner but also byInnvationsgruppen, Halmstad Fastighets AB and Anticimex.To be able to secure a whole building with only one product we came to the conclusionthat the product must be placed in the horizontal sewer pipe that connects with themunicipal sewer system. Our goal was to invent a product that prevent rats from passingand at the same time not affect the water flow.

The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant. By also documenting how much time we spent involving users we will show to which degree user involvement is effective. We found out that a couple of fast techniques could get very much result in the form of usability enhancing suggestions to the developers.

This report describes a project, which was carried out as a final thesis covering 30 ECTS during the final semester of the Master of Science programme Industrial Design. The assignment was issued by Fagerhults Belysning AB in Habo. The assignment was to design a family of products in which LED was to be used as a source of light. The main focus in the initial part of the project was to find a way to design the inside of armature which was suitable for LED technology. An armature, already in the range of products at Fagerhult, with the desired qualities that was to be strived after was the Zintra. The lighting source of the Zintra is a compact fluorescent lamp.

The aim with this thesis is to examine how childrens librarians apprehend and use the nationally initiated reading project Bokjuryn as an instrument in their work. The main question is as follows: How does Bokjuryn work related to the way public libraries pass on literature? Two questions are asked: How does the childrens librarians use Bokjuryn as an instrument and how do they motivate their work with it? and How do the childrens librarians view the reading project Bokjuryn as a method of passing on literature? The study is based on qualitative interviews with five childrens librarians. As a theoretical starting-point Jofrid Karner Smidt´s work about mediation of literature has been used. A model has been created and used based on Louise Limbergs analyses of the differences between school libraries and public libraries to analyse the result of the interviews together with other literature.

A consultant is an external expert that exists within all types of organizations. The consulting service can be divided into individual practitioners and large companies whose sole task is to hire out consultants to clients. The need for consultants has grown due to the restructuring of Swedish businesses during the past decades. They have put parts of their business on contract. This has led to a market with other player that have been able to focus on these parts.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.

Introduction: The number of hearing impairments in Sweden is increasing. The largest increase is seen in ages 25-44. There are reasons to believe that these impairments are noise induced. Leisure time noise is not controlled in the same manner that industrial noise is. An ongoing conflict between city council officials and rock club owners, musicians and music event organizers about sound levels at smaller live music clubs exceeding the national sound level restrictions created the need for an acoustic intervention project.

AbstractThis report describes our ten week long thesis work which is the last task in our education in mechanical engineering at Linköpings University. The project has been performed at Siemens Industrial Turbomachinery AB?s service department. The company which is located in Finspång produces, sells and provides service for steam and gas turbines around the world.The purpose of this project is to help Siemens develop their maintenance programs for two of the auxiliary systems which are a part of the complete steam turbine system. These are lube and control oil systems.The project is restricted to two of Siemens maintenance products, No Stop Check (NSC) and the annual Safety Inspection (SI).

The current system is installed, configured and controlled from a control panel for all audiences.

Abstract This thesis is based on a case study of the drawn out legal process on the question of establish a limestone quarry in Bunge Ducker in north Gotland (Sweden). The current fields are located next to areas that are protected by virtue of being EU-certified Natura 2000-areas. Despite this, the Swedish governments and courts have not agreed in witch national interest that should be prevail when decisions are made on this issue. This phenomenon are reflected in the judicial process and different court have evaluate information differently in the case. A change among governmental actors where priority is given to the importance of national interest have occur in the later part in the process.

The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

The following study is a discourse analysis of the concept of critical thinking within pre-school teacher education. It considers the following questions: how does the concept of critical thinking appear in policy documents, central to the pre-school teacher education, and which possible conceptions of critical thinking are conveyed by students and teachers active within the education. Additionally, the study seeks to discuss, as well as suggest a possible relation, between the findings of those two questions. In reviewing the material (consisting of five semi-structured interviews with students and teachers, and of a selection of policy documents central to the education), I argue the existence of a sort of project within the education, which presents critical thinking as a higher value. At the same time, I argue that the concept is not defined or concretized. This project, however, as I suggest while drawing upon Foucault?s ideas of discourse and government, involves a rather high degree of control.
