Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.

During natural conditions cattle live in large herds, which are divided into subgroups of 10-15 animals. Humans have held cattle for over 9000 years. Today we mostly have cows for milk and meat production during more or less intensive forms. Most of the Swedish cattle have the opportunity to graze during the summer time. This partly arises from the Swedish Animal Protection law which stipulates that cattle must have the option to be outside and graze, also partly because it makes it easier for the farmer.

The Swedish Animal Welfare Act say that all milking cows must have access to pasture in summer time. That was a gift to Astrid Lindgren o her 80th birthday from the Swedish Government. Sweden is a predecessor in animal welfare, but how well do we live up to these big expectations? In this thesis I will examine how well the pasture for milking cows works. I have been interviewing farmers with milking cows and people in the business. I have also been searching information on Internet, and using the library of Alnarp. Cows that are kept on pasture are exposed to different kind of parasites, but on the other hand they run a smaller risk to getting acetonemi, pareses and udder infection. Veterinary Pierre Nordmark means that cows on pasture are more healthy then cows kept inside all summer.

Is it possible to conduct a joint organizational change despite different circumstances and different starting points, and still talk about the same organizational change? Can all the work that leads to more efficient operations fall into the same category? How can such concept gain legitimacy? The result shows that by talking about a concept, in this case, Lean, as something that leads to a better and more efficient organization, without for that matter have to set a defined content of the concept you still can present the process as one concept. Tough the concept will be practically blank. But there is still a rhetorical value in the concept of Lean. The organization institutionalizes the concept and obtains in this way legitimacy from its surroundings.

This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.

Todays gaming habits between women and men depends on the age range. Both sexes are playing but how do they create a character when they have free hands? Are there any differences from a gender perspective? The main purpose is to answer the question: How does women and men create characters in the computergame The Sims? By looking at the result of four women and four mens created character and then interviewing them for profound information, we have received data to answer those questions for our study. Data has shown that the men were less personal when they created a character, used more imagination and took less time to create the character. The majority of the women created themselfs or part of themselfs and took more time on details..

The aim of this study was to understand how care staff in residential care perceive and work with elderly mental health and how these perceptions and work is related to aging. We have gathered our empirical material through eight qualitative interviews and vignettes with care staff in residential care. The study was conducted in a municipality with 10 000 to 20 000 inhabitants in southern Sweden. The material was analyzed with use of ageism as a theoretical frame of reference. The results showed that the care staff had different perceptions of mental illness in general and regarding the elderly.

BackgroundToday a common approach to solve a complicated problem is to assemble a temporary workforce in order to solve the problem by working together within a project. One of the difficulties with working in projects is to maintain the planned budget. Working hours and costs are often exceeded. Many companies presume that any certain project will succeed, a presumption that leads companies not to anticipate risks involved in a project. In companies today there is seldom time for evaluation or moderation of a project, in order to have time for evaluation there is a great need for an adequate planning of the project.IntentThe intention with this study is to create a model for planning, budgeting and evaluation of projects within consultancy companies.MethodWith the help of interviews and discussions within the group Hamnar och Byggkonstruktioner at Sweco has evidence to present a proposal on planning, budgeting and monitoring been developed.ResultsA model has been developed to ease for consultancy companies to plan, budget, monitor and evaluate projects.

Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation.
