Utmattningsberäkning av hydraulikkopplingar : Metoder och beräkningar gällande utmattningsteorier

The purpose of this thesis is to investigate the fatigue life of two components in different hydraulic quick couplings. The crack which initiates the fatigue failure usually occurs in the bottom of one of the threads. Thus, the threads in the coupling are carefully investigated. A few different approaches for determining the fatigue life are studied for each component. CAD (Computer Aided Design) models for both components are created and analyzed with FEM (Finite Element Method).

Simulering av elektriska förluster i en vindkraftpark : Utveckling av programvaran Wind Farm ElectricSystem Calculator (WFESC)

When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.

Miljökommunikation i dagspressen : En diskursanalys av hur SvD och DN framställer miljöfrågor

The starting point of this study is that the news media in general strongly influence which topics determine the public agenda by their choice of what is considered newsworthy. The study is based on articles from two major Swedish daily newspapers, Svenska Dagbladet and Dagens Nyheter. The aim of our thesis is to establish how the environmental public debate as portrayed in the newspaper corresponds to the environmental discussion within the scientific (subject matter expert) field, that is taught by the academic institutions, or if the two materially differ. The environmental communication discourse at the academic institutions advocates ?episodic? formation as the driving force behind transformation of attitudes and behavioral preconceptions. This episodic formation is aimed at incentivizing change by creating intimacy to the incident by linking cause and consequence to the individual citizen instead of to society as a whole.

Interaktiv patientportal : Generisk webblösning med tillämpning inom överviktsenheten

This report addresses the growing need to adapt the medical healthcare to the new possibilities that can be accomplished by incorporating a web aspect to the personal treatment plans of patients. It describes what implementations that need to be considered in order to successfully convert to a partially web-based treatment.The report also reflects the potential economical gain that can be made by keeping the communication between the patient and the doctor frequent. It also takes into account the personal gain to the patient by increased feedback and easier ways to communicate with their attending physician and thereby increasing the quality of their healthcare and service.The construction of a prototype of the system required is also included in the report as a description of construction and functionality of the prototype along with results and estimated outcome..

Socialtjänstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsätts för våld eller sexuella övergrepp i hemmet.

The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.

Djurvänlig hantering av lantbrukets djur i samband med transport

Handling, loading, transport time and unloading in connection to transport of farm animals affect animal welfare. Induced effects include both psychological and physiological stress responses in animals. The physiological parameters may be measured through blood analysis while behavioural changes often manifest themselves through increased vocalisation, escape attempts and apathy. Physiological parameters are additional parameters of importance when measuring animal stress responses. The handlers behavior during transport has been shown to have major impact on animal welfare and the quality of meat. Animal friendly handling and driving of animals create a more manageable work environment for the handlers. To further increase animal welfare in connection to transport, stables should be built with well adapted drift passage and ramps on the transport vehicle.

Den gode & den onde : En kvantitativ innehållsanalys och kritisk diskursanalys av Dagens Nyheters och New York Times rapportering av konflikten i Libyen 2011

This essay examines how the conflict in Libya in 2011 was reported by the Swedish newspaper Dagens Nyheter and the American newspaper The New York Times. The purpose is to examine how the conflict is portrayed and what similarities and differences that exist between the two newspapers. We have used a quantitative content analysis and critical discourse analysis to get our results. In conclusion, both newspapers polarize the conflict to a large extent, resulting in a one-sided and biased account. However The New York Times is more objective and neutral in its portrayal of the conflict..

Indexeffekten : En studie gjord på Nasdaq OMXS30 och OMXH25

AbstractMaster thesis in Business Administration, School of Business and Economics at Linneaus UniversityAuthors: Patrik Larsson and Pontus GislénSupervisor: Håkan LockingExaminer: Sven-Olof CollinTitle: The index effect- a study on Nasdaq OMXS30 and OMXH25Introduction: A significant part of the financial literature is based on the Efficient Market Hypothesis which assumes that prices in the market reflects all available information. Anomalies, such as the index effect, indicate weaknesses in this theory as it has been proved that it is possible to outperform the market using public information. Hence, the index effect can be linked to market efficiency which makes it interesting to study from a theoretical perspective. The mapping of the index effect is also interesting from a practical perspective, as it leads to a better understanding of whether investors and firms should take this anomaly into account.Problem: Is there an index effect, how does it behave and what can explain this effect?Purpose: The aim of this study is to investigate the index effect.

Utbredning av markvibrationer och stomljud från järnväg : Undersökning och anpassning av beräkningsmodell

The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from railways..

Textens spegel till Narcissus´minne : Ett betraktande av den egna skrivprocessen

In this essay I analyse three of my own texts included in an unpublished collection entitled till Narcissus' minne. Genres are discussed and a detailed study of how the writing process has progressed is done. The essay does not follow any specific literary or scholarly method of analysis, but to some extent the sphere of interpretation is explored. By associative interpretation the special logic of dreaming, the activity of the unconsciousness and the expansive accessibility of the memories, which characterize the texts, is traced. These structural features open a link to the way of psychoanalytical interpretation, but the essay does not strive for a complete account.

Filmkatalogisering: en behovs- och regelanalys

The aim of this thesis is to examine the characteristics of film cataloguing, and to compare general as in library use and specific as in archival use cataloguing rules. Most rules, both in archives and libraries, use the book as a point of reference. This is somewhat unfortunate on account of the great difference between books and films. The method used is studies of literature and qualitative interviews with three persons whose professional duties include cataloguing of films. The sets of rules which are studied are Katalogiseringsregler för svenska bibliotek KRS and The FIAF Cataloguing Rules for Film Archives.
