Förstudie för en vindkraftpark på Malmölandet i Norrköping : En undersökning av förutsättningarna för en vindkraftpark på ett sen tidigare planerat område
This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.
Perceptions of domestic solar systems : a study on non-adopter views of a new technology
The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany.
The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.
Lågstadiebarn och stress : Ur ett skolmiljöperspektiv

The aim of the study is to receive a deeper understanding of the use of textbooks in English teaching and to learn about why teachers choose whether to use the textbook approach or not. The study contains an analysis of the textbooks the teachers in our study used. The analysis shows the actual content and the types of texts together with the design and the structure of the textbooks.
Fairtrade coffee, fair enough? : a study comparing Fairtrade certified coffee producers and uncertified coffee producers in Aceh Tengah, Indonesia
This study compare if there is any differences between Fairtrade certified and uncertified coffee producers in Aceh Tengah, Indonesia. The aim was to compare the way the two groups of farmers produces their coffee and see if there were any differences between them, income, post harvest, production etc. During a visit in the district of Aceh Tengah, producers from both groups were given a questionnaire with questions about their farm and their production. The results of the questionnaires showed that the certified producers felt they had benefits being a part of a certified cooperative. Even with the experienced benefits the certified cooperatives gave the connected producers, like agronomy consultation and workshops the uncertified producers had a higher income from the coffee per hectare.
This study also indicated that introduction and presence of Fairtrade and the connection to the world market Fairtrade brings with it, has gained the entire area, for example with more stabile coffee prices..
Sambandet mellan saldodifferenser och effektiva materialflöden : Fallstudie utförs på Atlas Copco?s logistikavdelning
Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.
Kvalitetsarbete vid kontinuerligt enstycksflöde
hos Ferruform
Ferruform i Luleå är ett verkstadsföretag som idag bland annat tillverkar bakaxelbryggor till Scania. Som ett led i att både minimera slöseri och erhålla efterfrågestyrd produktion, vill Ferruform i en framtid gå över till ett kontinuerligt enstycksflöde. Syftet med studien har varit att kartlägga vad som krävs av Ferruform för att kvaliteten vid kontinuerligt enstycksflöde ska kunna säkerställas, samt presentera och rekommendera metoder för att möta dessa krav. Studien har avgränsats till avdelningen för skärande bearbetning, och har i huvudsak baserats på litteraturstudier och intervjuer. Filosofier från till exempel Toyota och reella kontrollverktyg som koordinatmätmaskiner, kontrollfixturer, probning, manuella mätverktyg och optiska system har studerats.
Användning av CAD-data vid NC-programmering
The degree project is performed at Metso Kamfab. The production is aimed on machines everything from handling of fiber to paper pulp. Metso Fiber and Kamfab are using Pro/Engineer for design and blueprint production. The processing department types the NC-programs in notepad on the basis of the blueprints, the CAD-dates that already is there are not used. The aim with the work is to study if Kamfab can use CAM-system for processing and production of programs for their NC-machines.
"Sprider sig som ringar på vattnet"
There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.
LAN-Uppgradering
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.
Granskning av kvalitetssäkringsarbetet vid en ICC-profilbaserad trycksaksproduktion
To make your company change from a conventional workflow to an ICC-based workflow you need tomake investments in time and money. On the other hand you get your reward in terms of a stable andquality safe production. To choose this way of adjusting your company to new routines requires accuracyas well as a great deal of commitment. It is not only about having the right equipment. There area lot of factors that affect the quality of production.Our ambition with this report is to bring out the importance of general thinking when it comes toICC-profiling and to discuss on which basis printing profiles should be created.
Metoder att förhindra nedisning av vindkraftverksblad
ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.
Ett underlag för utformandet IT-baserade förslagslådor
En kvalitetsförbättrande metod som senaste åren blivit vanlig inom Hälso- och sjukvård är Lean Healthcare - en verksamhetsfilosof som går ut på att eliminera slöseri och skapa värde för patienterna. I takt med att informationssystem och informationsteknik (IT) har utvecklats har informationsförsörjning fått en allt viktigare roll i vårdprocessen. Tidigare undersökningar visar dock att vårdpersonalen upplever att det finns många brister kopplade till informationssystem och IT. En explorativ fallstudie genomfördes där kvalitativ data samlades in med hjälp av intervjuer, dokumentstudier samt observation. Syftet var att beskriva hur informationsförsörjningen påverkats i ett kliniskt mikrosystem och i en vårdprocess som infört Lean.
Verktyg för värdering av miljöpåverkan vid investeringar i det svenska elstamnätet
During the period 2009-2013, investments in the Swedish national grid increase by a factor of ten compared to previous years. In order to fulfil their mission to manage the national grid in a safe, efficient and environmentally sound way, Svenska Kraftnät (Swedish National Grid) needs to take all these perspectives into account while planning new investments. To compare and relate perspectives of technology, economy and environment the same yard stick must be used. That yard stick is commonly money. A problem arises however as environmental issues are difficult to price.The purpose of this master?s degree project was to develop a tool for evaluation of environmental impact related to investments in the Swedish national grid.
Koncerninterna vinstöverföringar - finns det någon strategi?
The purpose of our essay is to find out if there are any strategies for profit transactions in a group. To realise our purpose we conducted two case studies with interviews. But we can not draw any general conclusions.To conduct the research we had to build a theory. In this theory we found motives to do profit transactions and how to do it. We also thought that there had to be some conflicts between the motives and the manager´s interests.In our analysis we found that financing the dividend was a strong reason to make profit transactions between companies in the group.
Kartläggning av ställrutin och uppstartsförluster : En studie utförd vid tablettpaketeringen på AstraZeneca
Vid AstraZenecas fabrik i Gärtuna utanför Södertälje paketerar man tabletter i så kallade plånboksförpackningar. Förpackningen är tänkt att vara lite exklusivare än vanliga läkemedelsförpackningar, samtidigt som den ska vara enkel att bära med sig. Paketeringen är helautomatisk och man använder sig av totalt fyra stycken paketeringslinjer, där man under året har bytt ut och byggt om delar av maskinerna.Sedan år 2007 har man arbetat med konceptet Lean production och man har i nuläget kommit en bra bit in i det ?nya? tankesättet. Det finns dock fortfarande saker som inte fungerar tillfredställande, till exempel omställningen av paketeringslinjen som görs mellan varje order.
