A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Prosthetic leg can give a negative psychological effect to the user, which ends up in decreased self-esteem and that the user hides his handicap. xCover gives a more natural volume and a cool look. xCover changes the look of the prosthetic leg C-leg. The product is constructed by us, Patrik Svensson and Magnus Zetterqvist, for Christoffer Lindhe at Lindhextend AB. Christoffer has hired Martin Bergman at Smedjan 17 to make the design.

PAPRO operates within the Forest Research company and their mission is to develop value-addingindustry solutions. At present there are no good ways for mills to easily test the printing quality on newsprintpaper. There is a great need for a fast way to do this on different paper qualities; with a laboratory-offset press this can be both a time and money saving method. At PAPRO Forest Research, NewZealand, a laboratory offset press has been developed and designed, during the past seven years, concerningthis issue. Earlier projects were made concerning the press, e.g.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Introduction: Urinary retention is a common postoperative complication associated with bladder distension. Permanent damage to the bladder affects the patient?s quality of life and may lead to a lifelong inability to empty the bladder and needs of self-catheterization with the risk of urinary tract infection. Bladder distension was classified as the fourth largest health care related injury in Sweden in 2013. Bladder distension may occur before the operation starts and is more common among orthopedic patients.

This thesis purpose is to determine an explanation of the efficiency in a labour-market related project. ?Enter? is an EU-financed project with a focus on long-term unemployed workers in the district Härlanda, Gothenburg. Starting in September 2004, Enter offers individually based coaching and job guidance to totally 110 young persons with problems entering the labour market. The goal is to provide these people courage to find either full or part time employment or to start study.

Magnetiskresonanstomografi, MRI, är en användbar teknik inom flera områden, i denna uppsats ligger fokus på användning inom medicin. Fysiken som ligger bakom MRI presenteras, som t ex uppdelning av energinivåer och kärnmagnetiskresonans. Uppbyggnad och tekniken som ligger bakom MRI har även studeras. Sedan har det gjorts jämförelse mellan MRI, röntgen och datortomografi. Utöver litteraturstudierna har simulering gjorts. I denna del har en modell för hjärnan byggts i programmet Comsol Multiphysics.

The focus of our dissertation is masculinity which is often a topic of debate in today?s society concerning areas such as violence, sport and paternal leave. Male studies are a relatively new field which means there is a lot remaining to be explored. We have chosen to explore how social class reflects on male identity. The reason we have chosen social class as a variable is due to a focus in the general debate of identity amongst the social sciences towards identities formed through consumption in the world of global mass-media.

By exposing their products in blogs, companies have the opportunity to reach out to hundreds of thousands of consumers daily. Instead of using conventional Internet advertising such as banners and ads, some companies chose to make use of product placement in blogs. By choosing to expose their products in blogs, companies use a medium that blog readers are familiar with and can relate to, and can thereby solicit customers for their products and brands.We will examine whether product placements in fashion blogs are an effective way for businesses to market themselves and their products. We measure this efficiency, by keeping a record of the sales of ten product placed garment and accessories that we have selected from four of the largest blogs in Sweden. The stores we examine sales of product placed goods in are volume brand stores such as Zara and H&M etcetera.

The competition for Norway spruce pulp wood in Central Sweden increases, forcing the supply-structure of Holmen to face two important challenges. Firstly, it is of the outmost strategically importance to secure the long-term supply of Norway spruce pulp wood to the industries. Secondly, Holmen desires to increase the obtainable volume of Norway spruce pulp wood. This would enable the company to choose volumes in the lower price-segments and thereby decrease the dependency of costly marginal volumes. As this work shows, one part in managing these challenges could be to lower the quality standards concerning root rot (Heterobasidium annosum). Facts presented in the work shows that: 1. Technically, the TMP-industry of Braviken can handle a much more rotted pulp wood than that used today, although the cost of refinement increases.

Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .

Fortifikationsverket which is the landlord for the Swedish national defence has a great problem in their forestry due to the relatively large amount of metal objects in their timber. These metal objects cause different types of economical losses in the timber refinement chain. To enable out sorting of logs containing metal objects already in the harvesting phase, Fortifikationsverket is interested of the possibility to utilize some type of metal detector in a harvesting head for that purpose.The goal of this study was to, with help of a case study, enlighten the problem that metal objects in timber cause for Fortifikationsverket and their customers of timber and to investigate conditions of to mount and utilize some kind of metal detector in a harvesting head at present.The saw timber deliveries by Fortifikationsverket during the time period 2003-2005 was used as a reference volume for calculations of economical losses. In this case study was included two sawmills where timber from Fortifikationsverket were delivered to for further refinement. Factors investigated were the type of damage metal objects caused in these two sawmills and the economical signification of these damages.

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.

In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.
