Safe operation of a large synchronous power system as Nordel is not an easy task.There are several aspects to take into consideration. This thesis focuses on the problems due to voltage collapses in a transmission system.The ability to foresee an upcoming collapse is vital to maintain stable operation of the grid. The grid operator at Svenska Kraftnät (SvK) uses the computer program SPICA to predict the maximum transfer limit at specified transfer sections. SPICA uses actual states from the grid to predict the transfer limitation, and a quarter later a renewed estimate is produced and so on. This means that the operator can se his transfer limits vary every fifteen minutes.Our task in this project is to validate the accuracy of the limitations obtained by SPICA.

The purpose of this Masters thesis is to examine how young womens sexuality is described in Swedish youth novels. The analysis is based upon eight books of which four were published during the period from 1970 to 1975 and four books were published during 2000 to 2005. The theoretical framework is based on a gender theoretical perspective where Yvonne Hirdmans theories about a gender system and Ylva Elwin-Nowaks and Heléne Thomssons ideas about gender construction are crucial. Also Anthony Giddens theories about sexuality in the late modern society are used, where the plastic sexuality and the pure relationship are central ideas. The method is based upon textual analysis, and a model of analysis is constructed with its basis in the theoretical attempt.

The purpose of this masters thesis is to study two subject gate-ways within the field of Swedish higher education and academic research, concerning structuring and selection of Internet resources to facilitate information retrieval for their target groups, and also to study two co-operation projects in the same field, one national and one European, to see how the co-operation is being carried through and how the gateways in the projects can serve from a wider perspective. The gateways, AGORA and NOVAGate, are being studied mainly by their Web sites and two e-mail interviews with persons responsible for the gateways. Facts about the national project are principally based on an interview with BIBSAM. The European Renardus is being studied out of articles and information on the Web site. From the results of the study it is being clear that the purpose of the gateways is to make a quality-selection of information accessible via the Internet and thereby facilitate for their target groups to find usable information.

Cochleaimplantat (CI) har använts i cirka 25 år för att återskapa hörsel hos barn och vuxna med medfödd eller förvärvad hörselskada/dövhet. Det finns fortfarande ett stort behov av kunskap om barn med CI och deras anhöriga. Syftet med studien var att undersöka upplevelser av förväntningar, förändringar samt livskvalitet hos vårdnadshavare till barn med CI sedan barnets CI-operation. Studien riktade sig till vårdnadshavare som hade barn med CI och var knutna till föräldraföreningen Barnplantorna vilket var 245 familjer. Antal inkomna enkäter var 153 stycken varav tre uteslöts.

2001 störtades ett antal flygplan in i World Trade Center och Pentagon i USA, detta genomfördes av organisationen al-Qaeda med Usama Bin Laden som ledare. Påföljden av detta blev att USA inledde sitt krig mot terrorismen. Skådeplatsen för detta blev Afghanistan som sedan tidigare har varit krigshärjat av Sovjet på 80-talet. 2003 vann DynCorp sitt första kontrakt kopplat till Afghan NationalPolice, detta innebar att de ansvarade för att utbilda poliser som skulle arbeta på lägre nivåer. Då Tyskland ansvarade för utbildning av poliser på nivåerna commissioned och non-commissioned.

Dagens samhälle kräver att varje enskild individ måste ta beslut över alla de val som vi ställs inför. När det gäller val som antingen gynnar eller missgynnar vår hälsa är möjligheterna idag oändliga. På grund av detta finns det många som ökar i vikt och därmed kan behöva hjälp med att göra en livsstilsförändring. Syftet med denna studie var att undersöka vilka faktorer som kan ha påverkat och motiverat i valet av att göra en gastric bypass operation, samt att urskilja vilka förändringar som följer efter den typen av livsstilsförändring. Semistrukturerade intervjuer genomfördes där fyra informanter deltog och studiens data analyserades med en kvalitativ innehållsanalys.

The projects goal is to construct and program a robot that is controlled from a computer but also have an obstacle handling function that allows the robot to navigate around the object by itself.The robot is a simple construction and the number of components and functions is kept at a minimum. A tricycle construction was chosen because it?s the simplest. Communication between the robot and the computer also kept as simple as possible..

How do you summarize the content of a fictional work, let?s sayLord of the Rings, into a few "telling" words that may represent it? This master?s thesis is a comparative study of how library users? freely chosen tags/keywords deviate from controlled vocabulary made by professional indexers when representing fiction. The thesis answers four main questions:? Do the tags that the library users give fictional works correspond to the categories used in professional indexing in Sweden?? Do the tags follow the standards for vocabulary, semantics and syntax used when indexing professionally?? Do the tags add something to document representations?? Are there differences between the tags used for adult fiction and the tags used for children?s literature?With a starting point in indexing theories of Frederick W. Lancaster, Annelise Pejtersen, and the semiotic theory of the indexing process of Jens-Erik Mai, 383 tags from totally 70 fictional works are analyzed.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Studiens syfte var att undersöka om patienter upplever att de fått tillräckligt med information inför sövning vid operation. Information är en viktig del i omvårdnaden, för att skapa en trygghet hos patienten. Många patienter upplever oro inför sövningen, vilket kan minska om patienterna är välinformerade. Studien bedrevs med en kvantitativ ansats som en enkätstudie på sju avdelningar på Karolinska sjukhuset, Huddinge. Frågeformuläret konstruerades av författarna inför studien och testades i en pilotstudie.

The Energy Market Inspectorate is implementing a new tariff regulation in Sweden. A small part of the new regulation concerns effectible operation costs and originally they where intended to be calculated using a modification of equivalent comparison standards, in Swedish Ekm. This thesis is intended to analyze if Fortums grid in Stockholm could be described correctly, using equivalent comparison standards. In Ekm every part of the distribution grid is designated a weighting in relation to 1 km 0.4kV over head line. These Ekm-measurements are intended to simplify comparison between different grid areas with different structure and geographical conditions.

During the past 30 years the fuels for energy production in heating and power plants have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances and particles into the flue gas. This is caused by the diverse components and chemical structures of fossil fuels and bio fuels. When the flue gas leave the combustion chamber and enters the path to the chimney particles in the gas are being transported out of the combustion chamber.
