Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

BakgrundSvensk sjukvård har idag bland de bästa behandlingsresultaten i Europa, men trots det förs diskussionen om sjukvården ofta i negativa ordalag. I ett försök att förbättra synen på verksamheten och bli mer effektiva har sjukvården i Sverige ofta använt sig av kommersiellamodeller, modellerna har dock behövt anpassas för att fungera i sjukvårdens miljö. En av de senaste kommersiella modellerna som nu införs i den svenska sjukvården är Lean Healthcare,som är sjukvårdens version av Toyotas produktionsfilosofi Lean Production. En stor del avtidigare forskning på området har behandlat Lean Production men lite finns att tillgå som handlar om Lean Healthcare. Den här studien är ett bidrag till att utöka kunskapen om Lean Healthcare i Sverige.SyfteSyftet med den här studien är att beskriva hur Lean-filosofin fungerar i den svenska sjukvården samt att göra en jämförelse mellan Lean Production och andra kommersiella modeller som tidigare har införts i den svenska sjukvården.GenomförandeMed hjälp av intervjuer på tre svenska sjukvårdsenheter har en fallstudie med fokus på Lean Production och Lean Healthcare genomförts.ResultatResultatet av studien visar att Lean Healthcare, i likhet med tidigare modeller, har krävt anpassningar för att fungera i sjukvårdens kontext.

This report is about the issue with decreasing production rate mainly caused by failuresrelated to the multiswitch. The multiswitch is a machine at Gefleortens Mejeriföreningwhich has the function of distributing milk cartons from one incoming track into fiveoutgoing tracks. Milk cartons who gets stuck and there by causes the production to stop,is the mainly problem with this constructionThe purpose with this report is to understand the causing factors and make suggestions which can help solving these factors. By analyzing the machine during production, having contact with different suppliers, searching internet for information, 3d-cad drawings and the complementary with personal experiences, this machine has  been evaluated and as a result of this new problem has come to be known.The discovered problems was analyzed and resulted in new suggestions for alternative options. Later the most functional results was chosen and put as a suggestion for the new model.A new machine built with the suggestions from this report assures to be well adapted to the environment at Gefleortens Mejeriföreing and the problems it causes..

The purpose with this essay is to look at how categories of "us" and "them" are created, reproduced and categorised. The areas of politics and media are in focus, though they are powerful and influential actors in generating discourses.The method is qualitative analyses of current research and analyses of discourses, contexts and resources from an intersectional perspective. Intersectionality presents a theoretical tool for complex understandings of power as it takes its point of departure in an understanding of power as multidimensional and one where gender, ethnicity and class are constitutive and bearing principals. Intersectional analyses aim to understand how these dimensions are created and changed in relation to each other and how they interact with specific gender orders in specific contexts.The analyse shows that "immigrants" are in a subordinate position compared to "Swedish" when it comes to resources, contexts and discourses. The analyse indicates the relation of power between "us" and "them", where "us" have the power and with that preferential right of interpretation in discourses, contexts and resources.

The assignment is issued by Scania Maintence AB seeking a new approach to detect power changes in their industrial processes. The work has taken place at Ångströmslaboratoriet and tests have been performed at Scania AB Södertälje.Today?s society consumes enormous amount of energy. In both economically and environmental view, it is important that the processes are effective, with high power factor. There are many ways to measure power in the industry, what they all have in common is that the installation is advanced, requires time and planning.

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.

This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.

The aim of this study is to increase knowledge about how a group of newly graduated social workers reflect on the practical daily work and their positions working with clients who are in need of social and/or economic resources. More precisely the purpose is to find out how these seven newly graduated social workers viewed working with clients during theoretical and practical studies. The aim is to analyze which techniques and methods could be seen in these narratives. Furthermore the aim was to find out if and how these seven social workers reflected on the power relation between social worker and client.The material of this study consists of seven semi-structured interviews. Throughout gathering the data and analyzing it, the qualitative method in form of narrative approach was used.

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

The main aim of this study is to examine the development policies of Sweden and the European Union from a postcolonial perspective. Sweden and the European Union are increasingly coming to be viewed as normative powers rather than military powers. So how does the colonial past of the western societies affect the policies of today? Are there any signs of the power structures of the past, and if so, how are these power structures manifested in the development policies of today? Since both Sweden and the European Union have come to be viewed as normative powers they are compared with each other to highlight their similarities and differences. The results of the study shows that both Sweden and the European Union can be seen as carriers of western values and interests.

This paper develops a theory for understanding negotiation situations involving states and indigenous peoples. Using relevant constructivist theory as a starting point, the paper develops a theory about understanding the relationship between power and culture implicit in the concept of the state. This relationship is examined in negotiations situations involving states and indigenous peoples. States are constituted by social structure and are representatives of the national culture. At the same time states are actors within the international system and a part of the culture of Westphalia.
