Bibliotekets tidskrifter och tidskriftsavdelning: En undersökning av högstadielevers läsning i relation till utbudet.

The aim of this masters thesis is to examine the supply of magazines and periodicals for young people at the library. We also examine young peoples reading of magazines and periodicals and compare the librarys selection with what young people read. The main questions of this thesis are: What do young people do at the library on their spare time? What weekly magazines and periodicals do young people read? What range of magazines and periodicals do the city- and the school library have? Where is the department located and how is it designed? What kind of relationship is there between young peoples reading and the selection? To answer these questions we have done an interview with a librarian and a questionnaire among 13-16 year old children. We found that it is not often that young people read their magazines and periodicals at the library.

Digitizing the Parthenon using 3D Scanning : Managing Huge Datasets

Digitizing objects and environments from real world has become an important part of creating realistic computer graphics. Through the use of structured lighting and laser time-of-flight measurements the capturing of geometric models is now a common process. The result are visualizations where viewers gain new possibilities for both visual and intellectual experiences. This thesis presents the reconstruction of the Parthenon temple and its environment in Athens, Greece by using a 3D laser-scanning technique. In order to reconstruct a realistic model using 3D scanning techniques there are various phases in which the acquired datasets have to be processed.

En vindkraftparks inverkan på Gävle Energis elnät

The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.

Kärnkraft : Ett arbete för drifttekniker?

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Selektiv uppmärksamhet och reaktion på stress

Tidigare forskning har visat att selektiv uppmärksamhet (selective attention; SA) mot hotfulla stimuli kan predicera emotionella responser på stressfyllda händelser. Syftet med denna studie var att undersöka sambandet mellan sårbarhet för ångest i form av SA och fysiologiska samt självskattade stressreaktioner på en laboratoriestressor. Ett negativt samband mellan fysiologisk stressreaktion och SA samt ett positivt samband mellan självskattad stressreaktion och SA förväntades. Skillnaden i hudkonduktansreaktivitet (skin conductance reactivity; SCR) på subliminalt presenterade hotfulla och neutrala stimuli hos 41 försökspersoner utgjorde mått på SA i denna studie. Försökspersonerna utsattes senare för en laboratoriestressor samtidigt som hjärtfrekvensvariabilitet (heart rate variability; HRV) och hudkonduktansvariabilitet (skin conductance variability; SCV) registrerades.

Ljuslyktan Ballongen :  

During my final examination project, I have been working with a design process to develop a new set of candle lanterns for the company Sagaform AB. This company has a large and significant role on the Swedish interior design and retail market. The assignment was developed when the company stated that they would like to supplement and expand its existing range of products. The research and surveys I have done have helped me to create eight different concepts and one of them ready to compete with the existing candle lanterns on the market. The result of my concept proposal expected to be included in Sagaform?s 2013 spring catalogue. During the project I have developed 3D-rendered images, a physical model, and a solid foundation for making prototypes. The Balloon has an attractive design language that fits both every day and more festive events.

Handelsbranschers användning av Augmented reality : En studie om dess möjligheter, utveckling och användning

Augmented reality is an interesting technology which has increased in popularity the last couple of years. Even though we see more and more of this technology the use of it doesn?t match up to its true potential. This paper aims to investigate the possibilities of this technology and illustrate how companies can use it in their business to reach out to customers in a new and exciting way. The study consists of three parts.

Frihet, Säkerhet, Rättvisa - En diskursanalytisk studie av Frontex roll i EU:s gränspolitik

This is a study based on discourse theory in purpose to examine the border-politics ofthe EU. Since the EU step by step has developed into an area of free movement on capital, people and services, the external frontiers have been given prioritiy on the political scene. Development in recent years have put questions of foreign- and security politics on a supranational level, meaning that the EU-member states in a wider range now cooperate in these political areas.To handle the increasing ammount of (illegal) migration to the EU an independet agency, Frontex,was established 2005 in favour of coordinating the Member States in issues regarding bordersecurity. The focal point of this study is to critically examine the identity of Frontex by using Becks theory of risk combined with the theory of governmentality. By doing so I seek to highlight the relation between Frontex and the EU and also that of Frontex mission in relation to illegal immigration.

Det var en gång... : Halta-Cajsa berättade, en analys av småländska sägner

This essay is intended to illustrate the norms and values which can be deduced from the notifier Catarina Andersdotter and recorded by Gunnar-Olof Hyltén-Cavallius. Reflects the legends of the peasant culture and life during the later part of 1700´s and early 1800´s.                      In the background material, I have assumed the following conditions of life; faith, love, work and children. Since Hyltén-Cavallius is our filter between us and the notifier, I have examined his life and incorporated events that may be of interest of the essay. Catarina Andersdotter´s life is described in the essay to show the factors and living conditions in her life that influenced her choice of stories.                      The environment of the commons over time period is described for the purpose of the variables of the legends. Legends have been qualitatively and quantitatively investigated.                      The essay shows that most of the legends deal with mytical world and its creatures as well as the interaction with humans.

En enfärgad regnbåge : Hur den homosexuella normen formas i HBT-magasinet QX

The HBTQ-society is not a homogeneous group; it contains a range of different sub-groups. QX is Sweden?s biggest magazine aimed at members of the HBTQ-society. The purpose of this study is to analyze if the magazine is more directed towards gay men or women ? both by examining how many men versus women appear in QX, but also by looking at the different ways in which the articles are more relevant to either men or women, such as by tone, language or choice of subjects.In this study, we have analyzed twelve issues of QX, from January 2012 to December 2012, in order to get the most current results as possible.

The methods used are qualitative interviews and literary studies. A brief review is given of acquisition policies at public libraries and of cultural magazines and the important role they play in public libraries. Five interviews have been made at five public libraries to find out what factors affect the process of selection when it comes to cultural magazines. Two theories are used as a basis for the analysis of the result of the interviews and literary studies.

Nulagesanalys av svensk e-handel. En undersokning om hur tjanster anvands av foretag for at bemota kundkrav

The Swedish e-commerce has been established for about 25 years, with strong growth from the millennium onwards. The companies that are active within it has many different backgrounds. Mail order companies were some of the early adaptors but today it is also common for companies to first create the e-commerce part of the business, before opening a store. A long list of companies has over the years come and gone, the rotation of the e-shops that are popular have constantly changed. We asked ourselves why.We wanted to get an understanding of the Swedish e-commerce, both from a business perspective and from a customer perspective.
