The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.
Projektledning inom Lean IT
Inom IT-branschen läggs det mycket resurser på att effektivisera arbetssätt, och att hitta det optimala sättet att styra och leda projekt är en ständig utmaning. Dagens IT-organisationer befinner sig även i en situation där marknaden ställer krav på minskade kostnader men samtidigt en högre nivå av support och service. Utifrån detta har det genererats en uppsjö olika arbetssätt och tillhörande verktyg som alla har som mål att strukturera eller effektivisera systemutvecklingsprocessen. Ett av dessa arbetssätt är Lean IT som hämtar sina grunder från det väl beprövade produktionssystemet Lean Manufacturing.Inom systemutvecklingsbranschen arbetas det ofta i projektform och att ha en bra projektledning är ofta en av faktorerna bakom ett lyckat projekt. För att en projektledare ska kunna leda projektet till framgång krävs det att denne har en bra uppfattning om arbetssättet inom organisationen och projektgruppen.
Att eko-certifiera ett turismföretag : "Mycket svordomar, mycket svett, frustration och ilska. Och glädje, ja det var liksom blandat."
The purpose of this thesis is to analyze the regulatory power, efficiency and impact of export control on Swedish arms export from the 1980s onwards, linked to the delegation of authority of permit license to the Inspectorate of Strategic Products in 1997. An increase in the administrative sector, based on a collective decision making process and established criteria and guidelines, aimed to strengthen the control of arms export to non-democratic and problematic states. In short, the aim of the study is to investigate and analyze whether there was a decrease in the arms export to problematic states or not. On one hand, it is reasonable to assume that the introduction of the new regulation entailed a more strict arms export policy. However, previous research has showed that regulations are sometimes not effective since incentives to breach these may be present.The study begins by examining the Swedish case and situation in terms of arms manufacturing and export, as well as the delegation of authority and legislation applied to the field over time.
Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3
The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.

Abrasiv nötning av polymerer tillverkade genom 3D-skrivning
Volvo Cars in Skövde manufacture and assemble Volvo engines. When attaching the ignition coil to all 4-cylinder engines, a special mounting tool is required. This mounting tool is currently manufactured from injection-molded polyoxymethylene (POM), a thermoplastic. It has been noted that the life span of the tool is shortened as a result of abrasive wear that occurs during the attachment process of the ignition coil.An investigation of the possibility of manufacturing the mounting tool with a 3D-printer is undertaken in cooperation with ÅF, a consultant to Volvo Cars. A literature study is first presented to introduce broader knowledge on the subject.
PlusTak
Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

Styrglapp i produktionsföretaget : En fallstudie av Holmen AB
Uppsatsen utgår från resultatet av Holmen AB:s medarbetarenkät Holmen Inblick 2011 i vilken 55 till 65 procent av cheferna uppgav att de känner sig delaktiga i mål, budget respektive verksamhetsplan. Enkätens resultat avviker från ledningens önskade utfall, vilket i uppsatsen omnämns som ett styrglapp.Studiens syfte är att analysera vad som orsakar ett styrglapp genom att klarlägga varför och till vilken grad chefer i Holmen är medvetna om, och kan påverka, mål, budget och verksamhetsplan. Genom att förstå detta kan de åtgärder som krävs för att reducera styrglappet identifieras av koncernledningen. Studien avgränsas till att analysera hur organisationens struktur, kontroll och kommunikation påverkar styrglappet.I studien används en kvalitativ intervjumetod där 17 chefer på två bruk i Holmens koncern har intervjuats individuellt. Därtill intervjuades platschefen för respektive bruk samt Holmens HR-direktör.
Europas framtida konfektionsmarknad - dess förutsättningar för att återfå en stark position
Textil- och konfektionsindustrin blir alltmer globaliserad och ställs inför hårdare krav då konsumenterna efterfrågar allt billigare varor i snabb förändring. Sedan flera decennier har europeiska konfektionsföretag flyttat sin tillverkning till länder med lägre arbetskostnader för att uppfylla kraven om låga priser som europiska tillverkare har svårt att uppfylla. En stor del har flyttats till Kina men även till andra länder i Asien. Nu håller marknadsförhållandena på att förändras igen genom tillväxt- och utvecklingsländernas starka utveckling. Förändringarna syns tydligast på Kinas marknad genom stigande priser och mindre kapacitet för europeisk produktion.
