Webb 2.0-relaterad marknadsföring - Möjligheter och risker med marknadsföring i webb 2.0- relaterade webbtjänster

The purpose of this master?s thesis is to examine how some university students, who are using the libraries extensively, use and experience the public and the university library and what they expect from the two different library types. I also compare their expectations with the different tasks and aims of the two library types. To answer this I have interviewed seven students at the department of history of literature at Göteborg University. I have also studied some literature and research related to this subject, for example user studies about students and libraries and the information behaviour of distance students.

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.

Elektronisk Handel : Framtagning av två implementeringsmodeller

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

Dimensionering av ventilhus med avseende på skärkrafter

The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.

Mätningar och undersökning av elkvaliteten i elnätet på reningsverket GRYAAB, i Göteborg

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

Nautisk turism : en jämförelse mellan svenska och kroatiska förhållanden

AbstractA tourism genre that has developed in recent years is the nautical tourism, nautical tourism is described as a tourism genre that includes all activities in relation to water. Croatia is one country that has invested in and has good presumption for this type of tourism, and has also received an international recognition as a top destination within the nautical tourism genre. The purpose with this thesis is to increase knowledge about the nautical tourism development in Croatia, and to see if it would be possible to develop on Swedish conditions. Sweden is a destination with a large number of archipelagos, located in both inland lakes and along coastal areas. Stockholm archipelago is one of the world's largest archipelagos which has a long tradition as a tourist destination.

Implementering av CRM

Background: The fierce competetivness that characterize todays market force the companies to differentiate their offerings to a greater extent. The customers do no longer choose their supplier on the attributes of the products alone. Their purchase decisions also depend on the relationship the customers have with their supplier. With new customer channels like the Internet and advanced computer systems companies can increase the value for their customers through a better understanding of the customers needs and preferences. In this way companies can create longterm relationships with their customers.

Wes Andersons färgstarka värld : En studie av färg i film

 AbstractThe focus of this essay is the american director Wes Anderson and the use of colour in his films. I also put some focus on colour as a neglected element in film studies, and what has caused this neglect. In my own research, I have analysed three of Anderson's films: Bottle Rocket (1996), The Royal Tenenbaums (2001) and The Darjeeling Limited (2007). To get a broad sense of a films use of colour, I have investigated the colour scheme, the colours of the costumes, as well as colour patterns. I have also interpreted the symbolism related to certain colours and then used the results of the analyses to answer the question; "how does Wes Anderson use colour, and in which film is this most apparent?" A very generalizing answer to this question, is that Anderson use colour as a means of signifying the characters' feelings and ambitions, and also their relations to the themes of the films.
