The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

This study examines the cultural factors which necessitated the establishment of The Music Archives of Småland in 1991 in the city of Växjö. I wanted to know the importance of the local music tradition and the role of those people who worked to create an institution such as this. In order to do this I interviewed the chief collector of early folk music, Magnus Gustafsson, and made use of literary sources to devise questions and evaluate the results of the exercise. In this study I have made use of a model of a musical culture in a society, created by Lundberg and Ternhag, based on the theory of cultural fields by Pierre Bourdieu. According to this model, the stature of a musical culture gives different forms of musical expression certain roles, but these roles can be remodelled, reflecting perhaps political or ideological influence.

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.

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.

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.

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.

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.

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

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.
