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.

This thesis aims to describe and characterise the foreign policy change the United States has experienced towards Europe. This thesis claims that the United States is presenting a more supportive attitude today towards the development of the European Union. This more positive attitude has developed during successive U.S. administrations and has become visible since the end of the Cold War.Washington is today less ambiguous and less ambivalent towards the integration of Europe. The United States appreciate that a common foreign- and security policy in Europe is in accordance with American interests.

In Sweden, a big part of the energy use is used in the housing sector. Political goals and targets are set up which the housing sector needs to work towards. Apartment buildings are a major part of the housing sector in Sweden and therefore reduction of energy use in these kinds of buildings are key to lower the energy use in Sweden. But there are not only political incentives to reduce the energy use. Some energy?saving measures are directly profitable and should thus be performed.

The purpose of our study is to examine whether stress among social workers is present, and ifso, what strategies they and their supervisors use to manage work-related stress. The study isbased on a qualitative method. The data consist of interviews, with six social workers andthree supervisors. The study?s theoretical framework is based on KASAM, SOC-sense ofcoherence by Antonovsky, demand- control- support model by Karasek & Theorell, stresstheory by Hans Selye and coping strategies by Lazarus.

The purpose of this essay is to investigate which components previous scientific studies suggest that an efficient treatment for adolescents with behavioural problems should contain. For this purpose, an extensive review of scientific research conducted in Scandinavia has been read and will be presented in this essay. This essay also present an introduction to residential care in Sweden as well as to an alternative form of treatment for adolescents with behavioural problems called Multidimensional Treatment Foster Care (MTFC). The result of this essay suggest that treatment of adolescents with behavioural problems should be based on the emphasis of risk/resilience factors of the youth and that the treatment should be adapted to the youth?s individual personality and way of learning.

There are different types of risk, examples include credit risk, liquidity risk and financial risk. In DeMarzo & Berk (2011, s. 293) is a study presented which is based on the yield of different types of financial assets between 1925 and 2009, the study show that a high risk gave substantially higher reward. With the study as a background, it is interesting to study practical risk management within participants of the financial markets of Sweden. In risk management there are several theories about whether risk can be calculated and analyzed with scientific methods in practice.

This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University..

The corporate world has become increasingly unpredictable and complex. Several companies are dependent on a rapidly developing market. The development has created a positive impact on production but on working conditions it has resulted in increased work pace and load. Psychosocial and stress-related problems has increased. The development has also meant a greater awareness of work environment issues relevant to competition for customers and employees.

Since the 1990?s Open Access has developed into an alternative model for scientific publication. Today an increasing political interest in promoting Open Access is commonly channeled through the implementation of policies by research funders. However, in the scientific community the uptake and acceptance of the model has been of notably different character.This Master?s thesis examines the understanding of and attitudes towards open access among eight senior Swedish researchers and how these have been affected by the implementation of the Swedish Research Council?s Open Access-policy as implemented in 2010.

This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.

Syftet är att undersöka lärares och rektorers inställning till ledarskap i relation till den så kallade Monroe-metoden..

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

The aim of the present literature study was to define and describe the area ?compliance in veterinary medicine? (i.e. the way treatment recommendations are being performed) and discuss the factors that influence the level of compliance. Based on the findings, a model that intended to increase compliance in orthopedic postoperative rehabilitation of dogs was designed. In the daily work as a veterinary nurse it is essential that one provides the best possible care to the animals from the beginning to the end of the treatment.
