Bakgrund: Tinnitus och ljudkänslighet är symptom som tycks öka bland ungdomar. En förklaring kan vara att ungdomar tillbringar allt mer och längre tid i bullriga miljöer utan att använda hörselskydd. Syfte: Syftet med studien är att jämföra gymnasieungdomars attityder till stark musik i relation till olika självupplevda hörselsymptom samt med avseende på variablerna norm, risktagande och riskmedvetenhet.Metod: Enkätstudie på 281 gymnasieungdomar i åldrarna 15-19 år, om deras attityder till stark musik. Enkäten bygger bl.a. på frågor och påståenden från Youth Attitude to Noise Scale, Health Belief Model och Theory of Planned Behavior.Resultat: Personer med permanent tinnitus hade mer negativa attityder till stark musik än de som inte hade det.

The purpose with this thesis is to study how the arranging of archaeological objects in permanent exhibitions has changed over time. To find out about this I have been analysing three museums with prehistorical permanent exhibitions. The exhibition at Statens Historiska museum was produced in 2005, Nationalmuseum in Köpenhamn was produced in 1972 with additions from 1988 and 1995 and, finally, Malmö Museer exhibition which was produced in 1977. These exhibitions have been compared to analyse developments during the last 30 years. The result shows that there are different ideals within the exhibitions.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Rapporten fokuserar på MY500 som är en jetprinter som skjuter lodpasta påkretskort utan att beröra den. Syftet med rapporten är att undersöka möjlighetenatt ersätta den nuvarande skruvpumpen med en spiralpump. Intentionenär att utarbeta en prototyp där spiralpumpen drivs av en positionsåterkoppladlikströmsmotor (DC motor). Prototypen används för att verifierafunktionen hos den tidigare oprövade spiralpumpen och för att fastställa om enstandard DC eller växelströmsmotor (AC motor) kan användas för att ersättaden befintliga stegmotorn.Arbetet börjar med en undersökning av olika motortyper för att sedanskapa en Matlab/Simulink modell med den valda motorn och parametrar förfriktion och tröghetsmoment. Genom simulering används modellen för att undersökaolika reglerstrategier vilka omfattar både hastighets- och positionsreglering.Olika samplingsfrekvenser analyseras för att hitta en lämplig regulator.Prototypen används för att verifiera regulatorns beteende och för att fårealistiska systemparametrar.

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

The aim of this study has been to examine if an implementation of a One Stop Shop in the public sector and its IT-support can serve as a motor for business development. By examine the relation between the One Stop Shop and the public administrations we have tried to answer this question. The municipality that we have examined underwent a big change, seven years ago, when they implemented a One Stop Shop including a IT-support called Flexite. But despite these seven years and the fact that Flexite has changed approach from a Case Management System to a Support System for Business Development the municipality have not adapted to this change. .

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

One of the most discussed archaeological subjects is the neolitisation, and the start of a neolithic lifestyle which is characterized by several significant events. The traditional view has been that settled people were cultivating and breeding, but this picture has been questioned and changed in later years. The development is principally based on two models; that already neolithic people immigrated and took over, or that the new lifestyle gradually developed out of the existing cultures. Southern Scandinavia was characterized by a settlement pattern with permanent settlements which were complemented by temporary special settlements, but in time more domestic settlements originated. On the British Isles the settlements didn´t consist of permanent agricultural settlements but instead did the people here move freely between several short term settlements.  .

Vi vill även försöka förklara ett eventuellt samband med kvantitetsteorin.Tillvägagångssätt: I denna uppsats har vi genom att fastställa ett kointegrationssamband mellan tidsserievariabler kunnat genomföra en regressionsanalys mellan penningmängdsutvecklingen och prisutvecklingen för småhus avsedda för permanent boende.Slutsatser: Vi har funnit ett långsiktigt samband mellan utvecklingen i penningmängden uttryckt som M3 och prisutvecklingen för småhus avsedda för permanent boende. Sambandet mellan M3 och fastighetsprisindex för småhus kan förklaras med kvantitetsteorin..

Having an ileostomy can affect the quality of life. Quality of life is defined by Siri Naess as being active, relating well to others, having self-esteem and having a basic mood of happiness. The nurse?s task is to focus on the stoma care and work in a holistic way. The aim of the study was to describe how adults with permanent ileostomy experience their quality of life.

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.
