Analys av mellanspänningsnätet i centrala delar av Västerås stad
The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

The aim of this master?s thesis is to study the moderate party?s cultural motion 2005/06Kr:233 with the party leader Fredrik Reinfeldt as first author. If consensus rules, the party?s ideology should not be visible in the motion, but the assumption in the thesis is that it is visible.
Strategisk analys av den svenska byggbranschen- En studie av JM, NCC, PEAB OCH SKANSKA
Background: The construction industry is Sweden?s single most important industry branch with a significant influence on Sweden?s wealth. The political restrictions that once controlled the industry are today almost gone. This combined with an unbalanced supply and demand situation on the Swedish constructions market, caused by urbanisation, has led to increased pressure on the Swedish construction companies who now are forced to find new methods in their struggle to contain or increase their competitive advantage. Purpose: The purpose of this thesis is to survey: which strategic variables are of great importance in today?s Swedish construction industry with focus on the four main actors, JM, NCC, PEAB and Skanska.
?Corporate Social Responsibility?- Ansvarstagande i praktiken : En studie om hur H&M, Lindex & KappAhl säger sig arbeta med socialt ansvar
Background: The global responsibility for multinational companies is a current matter of subject. Now when the world increasingly is getting globalized, economic growth is created, which brings a bigger demand of responsibility on companies. The leading companies from every industry is often becoming the frame for how the production process works and is therefore exposed to outer pressure which, for example, is coming from consumers and the media. Since consumers at present are more aware of what they are buying and where it comes from, it is important that the companies take social responsibility. We have therefore studied three big companies within the clothing industry to see in witch way they are taking their social responsibility.Purpose: Our purpose was to explore how companies within the clothing industry describe their work with Corporate Social Responsibility, code of conducts and where the incentive behind this work is coming from.Method: We have, through a qualitative study, examined how three large companies work with Corporate Social Responsibility.
Estetik och funktion i stadsplaneringen : Substitut eller komplement?
This master thesis summarizes contemporary theories on secularization processes in the Western world, and compares these with the example of Sweden, which by many scholars is considered to be the most secularized country in the Western world.I do this by dividing the most influential theorists in five different groups. In each group I explain how the theorists formulate and motivate their positions. These groups are:1) The secularization paradigm, where secularization always accompanies modernization. (Therorists: Steve Bruce and Peter Berger (in the 1960s)2) The paradigm basically accepted, but revised to depend on existential security, rather than modernisation as such. (Pippa Norris and Ronald Inglehart)3) Religion returned in the public sphere.
Stubbtransporter - en jämförelse av tre olika transportsystem
In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.
Förröjning i förstagalling - vad kostar det och följer utförarna instruktionerna?
This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU.
The work was an assignment from the forest owners? association Mellanskog.
The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards.
This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.
Fordonsgas ur gödsel och vall
AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

Båtbottenfärger innehållande TBTO : huvudsaklig källa till TBT i miljön
Antifouling paint containing the biocide bisTributyltinoxide (TBTO) has been used since1960 to reduce the occurrence of fouling on hulls on boats/ships. January 1st, 2003 theantifouling paints containing TBTO were prohibited. This ban covered all use of paintcontaining the substance TBTO. The ban was introduced because of alarming observationssuch as development of imposex in aquatic non-target organisms. Imposex is the impositionof male sexual characteristics on mainly female marine snails and occurs due to exposure toTributyltin (TBT).
Efterfrågan av grova sågade dimensioner och hyvlade produkter bland Wallnäs AB:s kunder : en marknadsundersökning

Samarbete i försörjningskedjan för balans mellan en leverantörs utbud och konsumentens efterfrågan: en fallstudie i kosmetikbranschen
Grundfilosofin i Supply Chain Management är att matcha utbud mot efterfrågan. Den så kallade Bullwhipeffekten pekar på att variationen mellan utbud och slutkundens efterfrågan ökar ju längre bak i försörjningskedjan man kommer. Med det menas till exempel att försäljningskvantiteter som faktiskt säljs i en affär sällan speglar de orderkvantiteter som leverantören skickar till tillverkaren som försörjer butiken med produkter. Förutom variationer i utbud och efterfrågan visade det sig att bristande interorganisatorisk kommunikation, brister i prognosarbetet tillsammans med en bristande datastruktur bidrog till en låg servicegrad. Den senaste forskningen belyser hur variation som orsakats av bullwhipeffekten kan minskas, samt att en låg servicegrad kan förbättras genom ett ökat samarbete i försörjningskedjan.
