Problemen har prioriterats och förslag till lösningar har utarbetats.

Man blir påverkad av sitt kön vare sig man vill eller inte : En kvalitativ studie om skillnader i män och kvinnors musikpreferenser

Music has always been an important form of communication and it can be found in many different contexts including aesthetical, cultural and emotional forms. In the globalized society of today music can be distributed fast through radio, TV, CD: s and the Internet. For many people consumption of music is an important part of the daily life and it can contribute to shape an individual?s attitudes and personality.The main purpose of this study is to find out whether there are any differences between men and women?s musical preferences. I will apply an explorative approach using qualitative interviews to describe what causes the differences.

Automatisk trimning av drivsystemreglering från MATLAB

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..

Studien beskriver ett framgångsrikt projekt inom Entertainment och förklarar framgången med projektet genom att presentera sex stycken Key Success Factors.

Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

Porr och rasistisk propaganda på svenska folkbibliotek : skall folkbiblioteken tillåta ett fritt internetanvändande eller skall man kontrollera sina internetterminaler?

This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.

Stopptids- och avvikelseuppfo?ljning vid la?nga takttider : Fra?n avvikelse till info?rd fo?rba?ttring

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

Aggregatstabilitet, jordbearbetning och fosforförluster i ett typområde på jordbruksmark :

Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. In this study, soils from 50 fields were analysed with respect to aggregate stability as measured by dispersion of clay together with the content of total phosphorus (TotP), particulate phosphorus (PP) and phosphate phosphorus (PO4P) in the water phase. All soils were clay soils with clay content varying between 21 and 54%.

Porträtt av personer med funktionsnedsättningar : - En kvantitativ och kvalitativ undersökning om den bild SVT:s respektive TV4:s nyhetsinslag skapar av personer med funktionsnedsättningar

The study has answered the questions to what extent people with disabilities are involved in SVT- and TV4- news reports and how people with disabilities are represented in news reports. The material is based on 140 news items.The study has demonstrated that news reports SVT and TV4 have different grades of misconceptions about disabled people. Disabled people are constantly being reinforced by negative disabling terms, the disability being of central importance for the news broadcast and they still occur in stereotypical depictions. Through the image of disabled people forms the bed-rock on which the attitudes towards, assumptions and expectations of disabled people are based on. They are fundamental to discrimination and exploitation that people with disabilities face on a daily basis, and contributes significantly to their systematic exclusion from mainstream society.

Den demokratiska tillbakag?ngen i Ungern : En kvalitativ fallstudie av Ungerns demokratiska tillbakag?ng under perioden 2010-2025

This study analyzes Hungary's democratic backsliding under Viktor Orb?ns term of office between 2010 and 2025. The research questions addressed in this study are ?Which central institutional reforms can be identified as significant for Hungary?s democratic backsliding under Viktor Orb?n?s rule from 2010 to 2025?? and ?In what ways have these reforms contributed to a process of democratic backsliding?? The study is based on a qualitative case method. To be able to conduct this study, secondary sources such as academic literature and reports from international organizations have been analyzed in detail.

Raä 977 - En lokal och tre aktivitetsytor. : En tvärvetenskaplig undersökning av Raä 977 vid Vojmsjön i Vilhelmina socken

This candidate thesis concerns the ?all but forgotten? material from the bronze age site named ?Raä 977, Hansbo 1:3, Vojmsjön, Vilhelmina?. During 1975-76, an archaeological dig was carried out by Västerbottens museum led by Ulla Walukiewich in an attempt to preserve the information the site held, before it was destroyed by the erosion brought on by the recently regulated sea ?Vojm? (Vojmsjön). The archaeological dig yielded a stunning amount of finds, samples and information previously unknown.

Skjortan från Lunds domkyrka - En jämförande studie mellan den liturgiska mässkjortan och den profana särken under senmedeltid

The main purpose of this essay is to analyze the late medieval shirt found in the cathedral of Lund. It has been preserved in the church and later on exhibited in the museum of Lunds cathedral. The most interesting thing about this shirt is probably its close connection to the secular world, as well as to the church. At first sight it appears to be a liturgical garment, it seams to be far too big for a regular, profane smock or shirt, but in a letter received by the church of Lund from Christian I of Denmark this shirt is mentioned as a chemise, or smock. The questions I aim to answer on the following pages goes, what characterizes the chemise or smock? What characterizes the mass shirt or alba? How can you use this type of analyse to examine the shirt from the cathedral of Lund?.

Vibrationsisolering av gruvmaskinshytt

Detta examensarbete, på uppdrag av Atlas Copco Rock Drills AB, syftar till att kartlägga de problem gällande vibrationer som finns och uppstår vid användandet av produkten Scaletec MC och komma med förslag till lösningar på ett nytt system som bättre hanterar vibrationer än det befintliga. Lösningarna är avgränsade till hytten och hyttens koppling mot ramen. Kartläggningen av Scaletec MC visade att den största problemskaparen är den långa bommen med den tunga hydraulhammaren framtill. Den skapar rörelse i hytten både vid skrotning och vid transport. Vid transport är även den odämpade stolen, de ojämna vägarna och det faktum att axlarna är stela ett stort problem som genererar helkroppsvibrationer hos operatören.

Fichtelius-affären och public service-ideologin

With this master thesis I wanted to find out whether Erik Fichtelius, an SVT employee, interview project with prime minister Göran Persson is acceptable according to the public service ideology. In order to do that I used Swedish newspaper articles to analyse the so called Fichtelius affair. I also gathered material on SVT and the public service ideology. The master thesis is based on sociologist Manuel Castells theories on mass media and television as presented in the Information Age. Castells claims that in our time different areas, such as politics and television, are melting together.
