This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

This paper has evaluated a new type of prosthetic foot, X-Balance, which aim was to facilitate the performance on uneven ground for the user. This study have performed gait analyzes with three prosthetic feet, the X-Balance, Flex-Foot and assure Ottobock9192 on flat and uneven surfaces using 3D analysis system QTM (Qualisys Track Manager) and associated force plates. During the project a prototype of a design that can perform a mechanical gait were manufactured. The prototype has then been used to fulfill the purpose and objective of this study which is to make different final sets that demonstrate differences between prosthetic feet. Gait analyses of individuals have also been performed to get an idea of what normal gait is.

The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

The purpose of this work is to find out if the suctionvalve to the salivaejector for dental equipment in a simple way can be improved or if a new design is needed. The result of the examination of the suctionvalve shows that the friction between the piston and the seal is high and that this causes the valve in a few cases sheaves. The study concluded that only small changes in material or detail, improve the component..

Det här examensarbetet har genomförts i samarbete med Metso Dynapac AB i Karlskrona. På deras asfaltsvältar finns idag olika modeller av körspakar. De har samma grundfunktion och bör kunna samordnas till ett gemensamt reglage. Detta ger möjligheter att använda rationell tillverkningsmetod p.g.a. volymen.

This report is a result of a degree thesis at Luleå University of Technology together with Stram AB in Växjö. The project aimed to develop a size reducible bed, that gets small when folded and has a new slim design. The development of the new folding bed had the purpose to give Stram AB new ideas of how guest beds can look like and be used in the future. Information about Stram´s products and also information of other similar products on the market was gathered. A visit at a store, internet and interviews gave grater insight of the market, and of customer needs.

The BSC is widely used mangement tool that is turning the vision and strategy into operational goals. However, after analyzing the criticism received the BSC, it seems af its internal focus, rigidity, static-ism and mechanical mindset limits the company's ability to create a strategy that takes important external factros into account..

A new type of forest tree seedling, called mini seedling, has been developed by the University of Dalarna in Garpenberg, Sweden. Compared to traditional containerized seedlings that are grown for 1 ? 2 years, mini seedlings are grown for only 10 weeks. The mini seedlings are small, easily planted, cost effective, and reduce the amount of chemicals used in the nursery. Research has shown that mini seedlings tend to have higher overall survival rates than traditional container seedlings.

Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.

In recent years, Lean has been implemented in a variety of companies with focus areas that differ from the conditions that characterizes manufacturing. This transfer has contributed to fairly superficial results because companies almost exclusively focus on Toyotas methodology and not on the goal of Lean. The effort of transforming Lean from manufacturing to any organization requires a definition on a general level and a view of Lean as a system. One of the core principles of Lean and the foundation of continuous improvements is standardized work. In product development there is a negative view on standardized work, where the engineers state that the principle is not applicable for knowledge processes that include non-repetitive and creative work.In the framework of this master thesis literature has been studied to find support that standardized work is applicable for product development and areas that include knowledge processes.
