The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

In today's society, the internet is an important part of everyday life. Over recent years the number of electronic services has increased markedly. Communities such as Facebook, consume more of people's time than 5-10 years ago. How can public authorities benefit from these communities or are the municipalities not ready for this? The municipalities determine how their resources should be allocated based on the municipality's needs.

I denna enkätstudie undersöktes stress och välbefinnande hos 224 slumpmässigt utvalda föräldrar i Stockholmsområdet, med hemmavarande barn i övre tonåren. Ryff Well-Being Scale plus en nykonstruerad föräldrastresskala användes; den sistnämnda visade sig ha god intern konsistens och i övrigt godtagbara psykometriska kvaliteter. Tonårsföräldrarna rapporterade något högre välbefinnande än en tidigare normgrupp. Grad av välbefinnande, specifikt dimensionerna självacceptans (self acceptance) och kontroll över tillvaron (environmental mastery), samt frånvaro av negativa livshändelser under det senaste året, predicerade lägre föräldrastress, med 32 % förklarad varians. Varken föräldrastress eller välbefinnande visade på några systematiska samband med demografiska variabler.

The purpose of this study is from a case study develop a model that aims to cost effectively improve productivity in a manufacturing production process. The study highlights the importance of having knowledge about customer needs and using a holistic process perspective when improving productivity to identify the relations between the process stations and by this find problems that cause waste and losses in productivity. Tools and methods used to make production more efficient such as single minute exchange of die, spaghetti diagram, 5s and master production schedule is presented an applied in the model to see how these effect costs, productivity etc.Maintenance effects on quality and productivity in a manufacturing company will as well be covered in this thesis. The results and conclusions finally reveals how the process improvement tools, maintenance and production planning for example effects each other and why it is important to establish an attitude in the company where continuous process improvement should be emphasized..

Background: Businesses are traditionally valued with the so called Discounted Cash Flow-model. When valuing newly-started businesses, surrounded by high uncertainty, and whose capital mostly consists of unrealized business opportunities, the Discounted Cash Flow-model needs to be complemented if the total value of the business is to be captured. A valuation with the help of real options is capable of valuing these unrealized opportunities, which often exist in newly-started businesses. The unrealized opportunities are to be found in the business plan of the business, why this needs to be valued to capture the total value of a newly-started business. Purpose: To demonstrate what the use of real options can result in when valuing businesses.

The purpose of this study is to identify and make attitudes among social workers towards homosexual and bisexual people visible, examine how these attitudes relate to their actions in their professional role and how these attitudes and actions can be understood by theories of heteronormativity and power. The study is a cross-sectional quantitative survey in the form of a questionnaire completed by social workers. The result shows that there are two groups among the social workers. One larger group that reproduces a norm of acceptance toward homosexual and bisexual people and one smaller that reproduces a heterosexual norm. This reproduction of heteronormativity increases the risk for homosexual and bisexual people to be made invisible and treated more negatively in contact with social workers, which in turn can lead to worse health among the clients..

AbstractObstacles or opportunities? ? A study of the experience of collaboration of social welfare secretaries and school staff.The purpose of this study is to illustrate the importance of the work with children and youth through the joint efforts between different authorities. The study deals with the collaboration between the social services and schools in the Ludvika municipality. The objective of the study is to investigate how teaching personnel and headmasters in compulsory schools and the social welfare secretaries in Ludvika, experience the collaboration, and how this works. On the basis of the objective, we have formulated some relevant questions; To what degree are schools aware of the model of collaboration, which is the basis for collaboration within the municipality, and are there any differences in awareness between different categories of employees? Other questions deal with differences in how the social services and schools experience the collaboration, discrepancies between different schools in this regard and if the respondents? experience any obstacles and/or opportunities by the collaboration.Collaboration is, and has been, a pressing issue for a long time in the public debate.

The purpose of this bachelor's thesis is to examine the information needs and behavior of Swedish theater students. The aim is to get an increased insight into how theater students search and use information as they create their character roles and also to examine how the information seeking is integrated in the creative process. The findings of this study have been made through qualitative data gathered from five interviews with six theater students who are studying at the Swedish Theater Academy. These students studied between autumn term of 2014 and spring term of 2015. To analyze the result of the interviews four different theories? have been used, Carol Kuhlthau?s information search process model, Lars Höglund and Olle Perssons model of four domains, Lars Höglund and Olle Perssons information search barriers and Tom Wilson?s model of information behavior.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

In this thesis I discuss and analyze different factors, and different circumstances, that influence identity negotiation among the north american indians. I do this mainly by using two models.The first one is Druckmans three dimensions of identity; negotiating identity, durability of identity and spread of identity. Depending on how the identity fits in these dimensions one can se if, or how, they influence the negotiability.My second model for analyzing is Reeds ?fasteing and unfastening identity?, using this model I have tried to understand during what circumstances the identity is negotiable. The identity is more or less negotiable depending on where the indians live, who they are living with and also on their inheritance.My results shows that the indian identity is changing and developing over time but the main characteristics still remains the same.

To be able to compete on the market environmental Management System has become an important part of operations work. However, many companies still haven?t implemented an environmental management systems due to lack of time and the high costs. One of the companies with this problem is Falu Bildemontering. Their goal is to accredited according to the ISO 14 001 certificate.

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.

This study titled School Model of Norrberga- a New Model of School. Some opinions that six pupils in the sixth grade have of their school is an explorative study. The purpose of this study is to some extent explain the ideas behind this quite spectacular model of school and the intentions of the City Council of Norrberga as they decided that all the schools that were to be renovated or built in the town of Norrberga had to follow a specific script.   As I first visited The Moonlight School I was puzzled. How do the teachers work it out? But, above all: Do the pupils work it out? What do they think about their school? When I was to write my final essay I wanted to try to sort this school out in more scientific terms. There is a nice, warm atmosphere at the school and the pupils make good results.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.
