Optimering av ett färdigvarulager
Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.
Exploatering, kommodifiering och megaf?retag i popul?rmedia: En kvalitativ narrativanalys av datorspelet Cyberpunk 2077
This thesis aims to research how megacorporations are depicted in popular media by analyzing the video game Cyberpunk 2077. In this assignment I focus on how the narrative of said game discusses economic globalization, megacorporations specifically which is accomplished using a set of theories such as: exploitation, commodification and capitalist realism. The analysis is constituted using a modified version of narrative analysis in order to better suit my research field as well as presenting a clear and concise structure a reader can follow. This study concludes that Cyberpunk 2077 constructs a dystopian world with the megacorporations holding the political power where the majority is constantly oppressed by the 1% in power. Things that we find human are questioned and diminished in order to increase the profits of those in power which tends to be the megacorporations.

Ger systematiskt kvalitetsarbete bättre resultat i årskurs 9? : En studie av två skolor som fått kvalitetsutmärkelsen Bättre Skola
The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.
Kommunal självstyrelse - en myt? : En lokalhistorisk studie av Borgviks kommun 1861-1924
The hypothesis of this study is that the local government act in Sweden 1862 was an instrument for the state to keep its´ political influence on the local level. It did not open for local self-government. The swedish historians Dahlkvist and Strandberg description of the Swedish local government act support this hypothesis, as does the analysis of political scientists Pettersson and Söderlind. The general opinion that the local government act opened for local self-government does still exist among many swedish historians.This study had two aims. The first was to investigate the actual extent of self-government in Borgvik, a small municipality in Sweden during the period 1861-1924.
Om relationer och maktstrukturer inom delat ledarskap : Lustfull relation eller obalanserad soppa?
The aim of this study is to create an increased understanding of shared leadership and how it takes shape in the relationship between first-line managers in human service organizations. Shared leadership is seen as a complement to the traditional one-man leadership and briefly means that two managers share the role that usually is held by a single leader. The study has a qualitative approach based on semi-structured interviews with managers in human service organizations. The interviews mention the mangers thoughts and experiences about shared leadership and gain approval in the hermeneutic science field. The study is analyzed based on symbolic interactionism where perspectives from the theoreticians Mead and Goffman are used.
Barnkonventionens implementering i Lunds Kommun - en aktörsanalys
In 2002 the local council of Lund, Sweden, decides to implement the UN Convention of the Rights of the Child. A number of actors, such as the state, the civil society, the political society and the bureaucracy, participate in the political process with different authority and points of departure. This thesis studies the actors´ interactions from an inside perspective by applying concepts such as political power, democracy and implementation. The methodological departure is action research from within, a local NGO, the local board of Save the Children Sweden. The results of the study indicate that governance and steering of the implementation process at the communal level is weak.
Makten på Öland och i Möre : Järnålderns elit i ett lokalt perspektiv
The social elite on Öland and in Möre in the south east of Sweden during the Iron Age is described on the basis of the archaelogical record, such as graves, settlements and traces of pre-Christian central places. The material is discussed to see if traces of an elite are to be found. The power configuration between Öland and Möre is also discussed.
Utvecklingen av ett nytt såghandtag
SNA Europe?s handsaw concept is called ?Bahco Handsaw System? and is constituted by a saw handle with the possibility to switch between different saw blades. The sales of ?Bahco Handsaw System? products have not achieved the desired results probably due to the high price. Developing a more cost efficient handle, enabling a lower consumer price of the product, is assumed to increase the sales volume.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.
Utvärdering av labpilot - flödesbatteri : Experimentell studie
Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.
Utvärdering av ett större bergvärmesystem i en flerbostadsfastighet som har konverterats från fjärrvärme
This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.
Utveckling av snabbfäste och verktyg för byte av sågklinga
This thesis is based upon the work done at Westinghouse electric company (WEC)inVästerås during the spring semester of 2015 and describes the development of a quickcoupler with associated blade changing tool. These are meant to be used togetherwith a sawing tool that the company uses for the dismantling of nuclear reactors,which is performed under water.The aim of the thesis was to develop a complete manufacturing documentation withdrawings and related CAD models which Westinghouse later can use to manufacturethe tool and the quick coupler. It was also included in the assignment to, if necessary,modify parts of the saw tool to adapt these to the intended blade changing tool.A number of visits to the company's workshop was made during the time to study thesaw that the thesis is based upon. The purpose of these visits was to get a better ideaof the dimensions, construction and the field of use of the saw. On three of thoseoccasions various engineers and consultants accompanied us to discuss possibleproblems with different ideas.This was interspersed with information in the form of literature studies on quickcouplers to create a clearer picture of the nature of the task.When enough information had been gathered a functional analysis was made to dividethe main problem into subthis phase the idea and concept generating process took place.The methods used for this was mainly brain writing and brainstorming.
