Reglering av turbins ledskenor i vattenkraftverkmed hjälp av elektriska ställdon
Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.
Musikskolecheck. En undersökning om den nya musikskolechecken i Nacka kommun
AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power. ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant. As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol. Etanolens framtid vilar på bra lösningar för framställning. I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle. Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
Bolivia kvinnorörelser och multietnisk stat
This thesis examines the possibility of Bolivian indigenous women?s social movements? getting their demands of a gender equal society fulfilled in the new state which was initiated in 2005 when Evo Morales became the first president representing the indigenous people of the country. By using a qualitative method I have showed that although the Bolivian indigenous women?s social movements? historically has been significant political actors for social change in the country, with representation at both regional and national level, Bolivian women are still subordinated in the social and political sphere. By applying a feminist intersectional perspective which takes its point of departure in a understanding of power as multidimensional, where gender, ethnicity and class are constitutive principals, multiculturalism theories and a social movements theory framework, I have found that even if institutional changes, that opened the system increased the indigenous women?s social movements political participation in Bolivia, power structures based on gender limited their possibilities to influence both socially and politically.

Natursyn och kärnkraft / View of nature and nuclear power
Kärnkraften har så länge den funnits varit en omdebatterad energikälla. Syftet med denna
uppsats är att utreda och få en bild av hur och på vilket sätt natursynen hänger ihop med
åsikter om kärnkraft. Jag har redogjort för vad energi är, kärnkraftens historia i Sverige och
som energikälla samt beskrivit för- och nackdelarna med kärnkraften. För att kunna ge en bild
av kärnkraft och natursyn har jag genomfört kvalitativa intervjuer med personer som på olika
sätt är insatta i problematiken kring kärnkraften. Min undersökning visar bland annat att
natursyn är ett komplext och stort begrepp som vi bör vara medvetna om hur det fungerar i
arbetet för att förbättra miljön..

Investeringar i småskalig vattenkraft vid befintliga dammar : - En studie av teknik-, ekonomi- och miljöfrågor
In this thesis a method for evaluating investments in small scale hydro power is presented. An analysis of the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented.Hydrolyzer is the name of the Excel tool developed to evaluate investments. The tool requests input data from the user and then evaluates the investment and generates a sensitivity analysis.
Ändamålsanpassad TINA-sortering av sågtimmer :
Swedish sawmills of today suffer from unsatisfying economy with high costs and low
benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner.
Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way
gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are
mainly manual but can in some rare cases be automatic.
"Lite snyggare, lite mer partyaktiga, lite mer Paradise" : En kritisk diskursanalys av kön och sexualitet i Paradise Hotel
The purpose of this thesis is to examine how power structures concerning gender and sexuality emerge through the use of language in the Swedish reality show Paradise Hotel. Of particular interest is the representation of heterosexual relations in the show. Because of its interest in the relationship between power, gender and sexuality, the thesis is based on theories from gender and discourse studies. The specific theories referred to are Michel Foucault?s understanding of power, stereotypes according to Stuart Hall, Yvonne Hirdman?s gender system and contract theory, Judith Butler?s heterosexual matrix and R.W.
Att definiera omsorgsbrist : En kvalitativ studie om socialsekreterares tolkningar av 2 § LVU utifrån intersektionalitet och makt
This study regards the Care of Young Persons Act, LVU, and the 2 § that focus on parent inability to care for their children. The assessment of parent ability to care for their children is performed by social workers in different municipalities. The law leaves room for interpretation concerning how to assess parent ability and therefore we found it interesting to study how social workers interpret 2 § LVU. The study?s aim was also to seek an understanding of how different categories, like gender, race, class and physical and psychical ability of the parents affect the assessment of their parenting ability, with a intersectional perspective.
Beräkning av värmeförluster och energieffektivisering av elbussar
The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå. The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.
Nekande tvångsmakt i Operation Unified Protector
There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.
Kampen om dagordningen : Kan media anses vara en enskild politisk aktör
Abstract Essay in political science, C-level, by Patrik Larsson, autumn semester 2007.Tutor: Susan Marton The battle over the agenda-Can media be regarded as an individual political actor? The purpose of this essay is to study to what extent media can be regarded to function as an individual political actor. In other words, do the media have more power over the political agenda than the politicians and do the media influence how the politicians make their decisions. This research is a case study and to be able to complete the intention of this study I have used Maxwell McCombs and Donald Shaws theory, the agenda-setting theory. From this theory I have used four aspects to analyse my material which has consisted of editorials from a Swedish newspaper, interpellations and debates that belong to the interpellations. The aspect I have worked with are, how the problem is defined, who is responsible for the problem, what values and which solutions are expressed. I have used a qualitative text analysis as my methodological approach which means that the results of my study are my interpretation of the material. My conclusions are that the media in this case shouldn?t be regarded as an individual political actor because there is no tendency that shows that the media has influenced the government in their decisions concerning the real-estate tax.
Hantering av viktiga framgångsfaktorer vid utveckling av ett Data Warehouse
Business Intelligence may help organizations in making the right decisions byproviding data for analysis which can be presented to decision makers. DataWarehouse which is a central part of Business Intelligence can be built in severalways but the methods presented by Ralph Kimball and Bill Inmons are considered thetwo main methods. The solution provided by Inmon focuses on integrating the entirebusiness into one large database using relational database development. Kimballhowever proposes dimensional database modeling by creating one or more data martsand integrating these using a data bus. Previous research has shown that the quality ofa Data Warehouse can be measured through critical factors such as data quality andsystem quality.
