Präglad av kvalitet? : En idéanalys av folkbibliotekariers syn på skönlitterär kvalitet och hur den påverkar deras arbete
In the new Library Act of 2014, it is stated that public library supply should be characterized by quality. To investigate what this means for the library, I do a functional analysis of ideas of librarians' views on quality and how they work with purchasing, weeding and mediation. I have chosen to limit the essay to fiction for adults in Swedish public libraries. By combining the basal idea analysis, where I investigate librarians' ideas about quality, with an operational analysis of ideas, where I examine the effects librarians' quality ideas get for the daily work, Iwant to find out the librarians' quality ideals.The material I analyze consists of 18 questionnaires, filled out by librarians with responsibility for purchasing and / or thinning in libraries across Sweden. The analysis is done with an analytical schedule, that consists of a number of opposing ideal types taken from previous research on quality, purchasing, thinning or mediation.
Skype : En studie av faktorer som påverkar privatanvändandet av Skypes videofunktion
Our time is characterized by the development of new technologies that facilitate communication between people. The need for Video Mediated Communication (VMC) is increasing because people move to other locations due to migration and global mobility. VMC provides the opportunity for millions of people around the world to ?hang out? and see each other despite the distance in between. The world is "shrinking" because of the Internet and our perception of distance is changing.VMC is becoming increasingly available, in the form of applications like Skype and MSN for mobile phones and computers, and in addition, it?s practically free.The purpose of this thesis is to render a picture of the way in which people use Skype in the private sphere.
Analys av lageregenskaper utifrån mätningar i testrigg
Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.
Den fysiska planeringens påverkan på människans rekreationsmiljöer : tillämpning av de åtta parkkaraktärerna inom balanseringsprincipen
The development of our time, is due to great progresses in technology and an enormous ex-plosion of knowledge, has lead to an increased effort of our attention as a result of a boundless torrent of information . Higher productivity and efficiency in our workplaces and homes crea-tes fewer opportunities for rest, leading to a community where stress has become a national disease. Recreation is an important part of our lives in order to be able to deal with stress and is now considered to be an essential resource when it comes to sustainable development. Green spaces are therefore today viewed to play a considerable roll for the national health. Nature has proven to have positive influence on man which leads to a decrease in blood pressure, an increase in power of concentration and lowered production of stress hormones.
Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer
This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
After establishment closure : Individual characteristics that determine re-employment probabilities of displaced workers in Sweden
This paper studies the relationship between individual characteristics of displaced workers and the probability of re-employment. A competing risks hazard model is used, distinguishing between exits from joblessness to self-employment and to paid-employment. All individuals between 25 and 55 years of age, at the time of displacement, that suffered from at least one year of joblessness after being displaced between 1990 and 1998 due to establishment closures that occurred between 1990 and 2001 are included. This allows for the closure procedure to be between one and three years long. Each individual is followed, from the year of displacement until the year of re-employment or at the latest, ten years after displacement.

Utvärdering av den upplevda användbarheten hos CySeMoL och EAAT med hjälp av ramverk för ändamålet och ISO/IEC 25010:2011
This report describes a study aimed at uncovering flaws and finding potential improvements from when the modelling tool EAAT is used in conjunction with the modelling language CySeMoL. The study was performed by developing a framework and applying it on CySeMoL and EAAT in real life context networks.The framework was developed in order to increase the number of flaws uncovered as well as gather potential improvements to both EAAT and CySeMoL. The basis of the framework is a modified version of the Quality in use model from ISO/IEC 25010:2011 standard. Upon the characteristics and sub characteristics of this modified model different values for measuring usability where attached. The purpose of these values is to measure usability from the perspectives of both creating and interpreting models.
Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :
Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply.
The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.
De svenska fastighetsbolagens redovisningsval för förvaltningsfastigheter och dess effekter på redovisningens kvalitativa egenskaper : En studie av noterade respektive onoterade svenska fastighetsbolag efter implementeringen av internationellt regelverk
AbstractTitle: The Swedish real estate companies choices of valuation within investment properties and its further effects on the qualitative characteristics of accounting.-A study of the Swedish real estate companies listed and non - listed on the stock market, after the application of the international rule board.Background and Problem: From January 2005, all companies, listed on a stock market within the European Union, are required to prepare their consolidated accounts using common set of International Accounting Standards, IAS/IFRS. In Sweden, this opportunity has also been given to non-listed companies, to voluntary implement these rules in their consolidated accounts. One difference between Swedish accounting rules and contemporary International rules, deals with the accounting treatment of investment properties, which foremost affects the real estate market?s accounts. In contrast to the Swedish Financial Accounting Standards Council?s recommendation RR 24, the new standard, IAS 40, permits a choice between different accounting alternatives.
Mätning av axiella magnetiska läckflöden i vattenkraftsgeneratorer
This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering. To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.
Kön och ålders betydelse beträffande arbetstillfredsställelse utifrån JCM
Studien avser att undersöka om det finns någon skillnad mellan män och kvinnors
arbetstillfredsställelse definierat som aspekter av arbetssituationen enligt
Hackman och Oldhams (1976, 1980 i Arnold et al., 1998) Job Characteristics
Model, och om det finns några skillnader i ålder vad gäller
arbetstillfredsställelse utifrån JCM. Det var en explorativ undersökning
eftersom mycket av tidigare forskning har fått varierande resultat, och vi
ville se vad vi skulle få för resultat. Metoden som har använts är kvantitativ
och syftet har undersökts med hjälp av en enkät. Som teoretisk bakgrund
användes Hackman & Oldhams ?Job Characteristics Model? (JCM) (1976, 1980) och
den användes även vid utformningen av enkäten.
Genomgång av Turbomin 100 : Förstudie och föreslagna förbättringar av undervisningsjetmotor Turbomin 100
ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?. The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

De medeltida djurfigurernas idévärld : med kyrkomålaren Johannes Rosenrods exemplifiering
In the medieval ruling catholic time the church walls was swarmed with programs of pictures with religious motives there the animal figures rich symbolics was significant first and foremost for the illiterate. Principally the inspiration comes from the antiquitys pagan world of fables and bestiary Christian world of symbols with the bible as the essential source. The essay describes six of the most common animal symbols who occur; dragon, the sneak in the Paradise, mouth of hell, lion, the fox as a preacher and the devil.To attain to a discussion about why just animals are used as symbols for human characteristics in the medieval church art instead for human beings as it's actually be about, I have studied bestiary and other literature about medieval churchpainting to get an understanding about the history of ideas about the thoughts of the time and about symbolics of animals, worth and how the Christianity have had an influence on the pictures.I have used Johannes Rosenrods church pictures from Tensta church in Uppland from 1437 as an exemplification but also mentioned other unknown painters who used similar animal codes and motives.It's plausible that the purpose of the animal figures was both religious and political, which was used by both the spiritual and the worldly authority so they could keep their dominance over the peasant. The figures was simple to read and remember and they made a deep impression on the people together with the sermon. The churchgoer get so to speak a sound- and image experience, a medieval reality who impress their world of ideas.When it's about the artistic formation of religious expression and characteristics it was undoubtedly a great advantage for the artists to use an animal code like a schemata.
