It is easier to swallow an elephant in pieces. A way of measuring flexibility and quality. A study of DAS.

Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.

Undersökande journalistik : En analys av Uppdrag gransknings dokumentär om IKEA

This essay is about power in the classroom. It is about the power dimension of the student-teacher relationships that arise in that space. The overall aim has been to investigate which categories are fruitful in a power analysis of these relationships. My aim has therefore been to develop power categories and to use them to identify and to categorise cases of power interaction that take place between those particular actors in that particular setting.In order to gather material for my study I have both read literature that approaches the study of the student-teacher relationships from a power perspective and done a series of observations in a high school.My theoretical frame comprises a concept of power and a series of power categories. These categories include strength, authority, inducement, coercion, violence, resistance as well as to possess power, to have power, to exert power, the scope of power and the base of power.

Scenarioanalys över Sveriges elproduktion år 2050 : Kan Sverige försörja sig med 100 % förnybar

The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.

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.

Medier, makt och rasism : En kritisk diskursanalys av svenska nyhetsmediers rapportering om Rinkeby

The aim of this thesis is to examine expressions of power and racism in news reporting about the district of Rinkeby, Sweden, in two major Swedish newspapers. News articles are examined using Norman Fairclough?s three-dimensional model for critical discourse analysis. The discourse theory has also been complemented with theories of media in relation to power, ideology and racism. The study has shown that news reporting about Rinkeby largely focused on stereotypical subjects such as violence, social problems and crime.

Sverige och implementering av EU-direktiv : En fallstudie av badvattendirektivet och arbetstidsdirektivet

The aim of this paper is to explain and compare non-compliance of two EU-directives, ?the quality of bathing water? and ?the working time directive?. This study answers the questions: Why didn?t Sweden implement the directive on bathing water quality and the working time directive correctly? Are the reasons for non-compliance the same or different in the two cases? The paper is designed as a case study and with an explanatory attempt we explain why the two directives weren?t implemented correctly in Sweden. The theoretical approach is based on both general- and EU-specific implementation theories.

Visualisering av produktionseffektivitet : Utveckling av ett verktyg för övervakningav avbrott och presentation av TAK

Many companies do not register all the stops that occur in a production plant, it often takes longer to report than to fix the problem. If no problems are registered, you cannot trace where the problems arise.This master thesis was performed at AcobiaFLUX and they have noticed an increased demand from their customers to trace problems raised in their processes. The aim of the thesis was to find out how a tool to monitor a process best could be developed. Then the most essential from the theoretical base was developed into a useful tool for operators. For the operators to know if the process utilizes the full capacity of a process, the tool presents a measure of the Overall Equipment Efficiency, OEE.

Vindkraft och landskap

The current debate about environment and climate change has contributed to more andmore investment in alternative energy sources such as wind, solar and biogas. The Swedish Parliament has set the target that wind power should supply 10 TWh in 2015.In Sweden, wind power establishment began in the early 1980s. Since then the development has gained a tremendous momentum. The purpose of this study was to find out what problems wind power brings and what power relations that exists in connection with wind power establishment and how the landscape is affected by windpower construction, focusing on some cases in Falkenberg and Varberg. This study shows that wind power establishment is a very complicated process.
