Dämplindningens inverkan på spänningens kurvform i en vattenkraftsgenerator

Harmonics are a well-known problem that has to be dealt with in the design of thegenerator. Internationally accepted standards limits the amount of harmonics allowedin the no-load voltage. These limits can be difficult to fulfill with integral slot winding,where the number of slots per pole and phase is an integer. The presence of thedamper winding often makes the problem with harmonics even worse and harmonicswith frequencies of order 6q±1 arise with significant amplitude. How the damperwinding is designed affect the content of harmonics in the no-load voltage and the aimwith these ? has been to investigate in which extent design of the damper windingaffects the contents of harmonics.Simulations with the 2-D finite element method have showed that if the damper barsis centered in the pole shoe, the amplitude of the harmonics of order 6q±1dependsboth on the ratio between the stator slot pitch and damper bars slot pitch and if thedamper bars are connected between the poles or not.If the damper bars is displaced with ¼ stator slot pitch alternately, the amplitude ofthe harmonics of order 6q±1 is reduced and the influence of the ratio between thestator slot pitch and the damper bars slot pitch will vanish.

?Så nu är jag ett annat jag igen? : Autenticitetsgränser i och kring JT LeRoys Sarah och Hjärtat är bedrägligast av allt

The aim of this essay is to investigate how the author JT LeRoy (a. i. Laura Albert) questions and broadens the concept of authenticity in literature and authorship. My study is based on LeRoy?s novel Sarah [2000] and the collection of short stories The heart is deceitful above all things [2001], as well as articles written about the construction of Laura Albert?s alter ego JT LeRoy.

UML i teori och praktik

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

Förekomsten av Personliga Egenskaper i Platsannonser : En kvantitativ innehållsanalys

The purpose of the study is to highlight educators' preferences and attitudes towards tablet in preschool by describing the use of this digital tool in the preschool educational activities. The use of tablet in preschool is in the study looked upon as a phenomenon. The description of the phenomenon is built on the analysis and interpretation of educators' statements about it. The research questions focus on the following aspects: educators' attitudes towards the tablet and its use in pre-school educational activities, the tablet's current area of use, the culture surrounding the use of this digital tool and the educators? statements about advantages and disadvantages of tablet's use in preschool.

En studie rörande brottspåföljder : Straffets legitimering

AbstractThe author Selma Lagerlöf was born in 1858 at Mårbacka, in Värmland and died in 1940. Fifty years after Selma´s death were her correspondence released and ten thousand of letters were found in the collection. But it was just the correspondence between Selma and Sofie Elkan who interested people because they wanted to know if Selma and Sofie have had a sexual relationship. Later, in time for Christmas 2008 the Swedish Television shows a film about Selma. "Selma Lagerlöf Society" was critical to the movie and thougt that the movie focused too much on Selma`s sexual orientation.

Outsourcing av urval och inköp : En studie av hur bibliotekariens kompetens och yrkesroll påverkas av Bibliotekstjänsts profiltjänster

Traditionally, the majority of Swedish public libraries have carried out most of their acquisitions through Bibliotekstjänst's binding booklets. In recent years, however, many libraries have complemented the binding booklets and other services from Bibliotekstjänst by other ways of acquiring books, such as Internet bookshops, while other libraries have stopped using the binding booklets altogether. There are various reasons for this development, such as Information Technology making it possible for librarians to compare prizes and services from different retailers. Another important reason is the need for public libraries to meet new needs from their patrons, while remaining on a restrained budget, which often causes a need for reorganization of staff and resources.As a way of meeting the new needs for libraries, Bibliotekstjänst has created Profile Services (profiltjänster), a service in which a library outsources its acquisitions to Bibliotekstjänst. The staff of the library, in dialogue with Bibliotekstjänst, design a profile for the acquisitions for the library in question, in order to determinate which types and genres of literature the library and its patrons are requesting.

Barnsligt lätt att hitta rätt? En observationsstudie om hur barn navigerar mobila applikationer

When the patient has difficulties to communicate to those around him due to his illness it is hard to preserve the patients right of self-determination. It is very important to consider the patient as autonomous during the course of the illness. Different alternatives have been developed to preserve the patient?s autonomy such as dedicate a deputy or plan the care of the patient in advance.Aim: The aim of this study was to describe, from an ethical point of view, how the patient?s autonomy could preserved at palliative care.Method: A general literature study where 11 scientific articles have been analysed from a qualitative checklist whereof the result has been discussed based on the principles of ethics.

En kartläggning och utvärdering av vårdkvalitet inom den rättspsykiatriska öpenvården i Malmö: utifrån ett patientperspektiv

The aim of this study was to map out the quality of the treatment in the forensic outpatient care unity in Malmoe from a patient point of view. This target group, seriously mentally disordered law-offenders, has been neglected in the scientific research. This investigation will hopefully contribute to a positive change in this subject. To achieve a good understanding of this field a methodological triangulation was conducted which included an observational study, a pilotstudy and semistructured interviews. 14 patients and 10 staff members were interviewed.

Rörelsekapital och lönsamhet : Finns det ett samband?

Syfte: Syftet med denna studie är att undersöka sambandet mellan rörelsekapital och   lönsamhet för företag i olika storleksklasser på svenska maskintillverkande företag.Metod: Studien baseras på en kvantitativ metod för att undersöka rörelsekapitalets samband med lönsamheten. Datan som användes i studien hämtades från retriever business och uträkningarna gjordes i Microsoft Office Excel. Variablerna storlek på företag, utvecklingsfas och rörelsekapitalspolicy användes för att kategorisera datan i flertalet tester.Teori: Studiens rörelsekapitalsmått var kassacykeln och lönsamhetsmåttet var bruttovinstmarginalen.Resultat: Studiens resultat visade att det inte fanns något samband mellan rörelsekapital och lönsamhet i 13 av de 24 undersökningarna.Slutsats: Studiens slutsats är att sambandet mellan rörelsekapital och lönsamhet skiljer sig åt hos företag i olika storleksklasser på svenska maskintillverkande företag..

Datainsamling av privatpersoners internetbeteende : En studie av medvetenheten hos privatpersoner

Projektet att etablera vindkraft : möjligheter och risker med ett förnybart energisystem

This thesis describes the processes of establishing wind farms in Sweden. The workcontains a thorough literature review regarding both the establishing process andproject management, including complex project theory. The main part consists of theexecution of 15 interviews with organizations involved in wind farm establishment.The result of these interviews laid the foundation for a process description identifyingdifferent steps and activities in these types of projects. The outcome was thencompiled in a project model, which includes five phases and four processes.When analyzing the project of establishing wind farms from the theory of complexprojects one discovers that the amount of different requirements and stakeholdersnecessitates a systematical and dynamical project structure. Since projects are in needof different types of competences there are also many consultants and contractorsinvolved.
