Konceptuell design och utveckling av hybridfordon
This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

Title: Shop at us ? and we?ll carbon offset! ? How large and well-known companies affect consumers feelings towards their brand by using green marketing and CSR.Authors: Emilie Jäfvert & Carolin RuthbergAdvisor: Christine TidåsenLevel: Bachelor thesis in Marketing, (15 Swedish credits), Spring 2011Keywords: Green marketing, CSR and branding.Question: How do large and well known companies affect their customer?s view towards their brand by using green marketing and CSR?Purpose: The purpose of this thesis is to investigate how high consumer?s value companies who works with green marketing and CSR, and also to find out how it affects the company brand.Method: We have chosen to do a qualitative research with a deductive approach. We have done five open interviews with companies and ten open interviews with consumers to conduct our research.Theoretical framework: Our theoretical framework includes four different areas; CSR- Corporate Social Responsibility, green marketing, brands and consumers. These sub-chapters include theories that will help the reader get a better understanding of the areas.Empirical studies: We have gathered empirical data by multiple open interviews. Two of the five interviews with the companies were face-to-face, two via email and one over the phone.
Carbon sequestration in the pastoral area of Chepareria, western Kenya : a comparison between open-grazing, fenced pastures and maize cultivations
Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).
Effekter av landskapets sammansättning på humlearters förekomst
The species in the genus bumblebees (Bombus) are important pollinators. In the world there are 250 bumblebee species and there are 34 species in Norway. The purpose of this study is 1) to assess changes in the species composition of bumblebees in twenty different places in Norway that have been inventoried first one time between 1939-1960 and the second time in 2012, and 2) to relate species richness and distributions to current landscape composition with the aid of orthophotos. In this study, I have used regression analyzes on the different bumblebee species that were present or absent at the inventory, using the premises of the following variables: low or high altitude, latitude, longitude and seven different types of land use (farmland, building/plots, open land/pasture, forest, wetland and open or snow-covered ground above the tree line) to see if there was any relationship between each species and the different variables.
I have not analyzed what the landscape looked like at the first inventories and therefore we cannot say whether it has changed and if that is why species number has decreased. This would be interesting to study further and to see if there is any relationship between landscape changes and bumblebee?s species decline.
Identifiering av stelkroppsmodell för industrirobot
In this masters thesis we consider a method for experimental identification of the inertial parameters of an industrial robot, using measured torques and joint angles. A dynamic model of the first three joints of the robot has been identified.To achieve good identification results, it is important to carefully choose the trajectory for the experimental identification. A method to generate trajectories using two suggested design criteria has been used and evaluated using an ABB industrial robot, and one of them yields good identification results..
Modellering av en panna med rörlig rost :
The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Matematik och naturvetenskap i barnens fria utomhuslek - en observationsstudie
Title: Besparingar inom Barn- och utbildningsnämnden.Seminar date: 29th of May 2009Course: Degree thesis in Business Administration, bachelor thesisAuthors: Amela Smajlovic and Sten SundfeltAdvisor: Leif HolmbergPurpose: Our purpose is to explain the cost-saving process that many municipality organisations face because of the global financial crisis.Limitations: We have limited our study to the municipality of Landskrona and Kristianstad.Method: Our study has a qualitative approach. By using open interviews we have been able to get an open dialog with our respondents.Theory: We have compared with different theories, such as Rombach?s budget-theory and Wildavsky?s role theory.Empirics: The material is based on interviews and conversations with key figures in different levels of the organisations in Landskrona and Kristianstad.Conclusions: The success of a cost-saving process depends on the engagement, awareness and how inclined to changes the persons in the organisations are. Has everybody the willingness to take responsibility fore the organisation and the changes that the surrounding world claims?.
"Vill du missbruka så blir vägen rätt smal" - Förklaringar till varför hemlösa kvinnor med missbruksproblematik utesluts från den reguljära bostadsmarknaden
The background of this study stemmed from the notion that the majority of homeless women with substance abuse, most of all, wanted a secured place of their own to stay. Few involved professionals agreed and instead of perceiving housing as a human right the women were mostly offered various types of short-term social housing. The purpose of this study was thus to examine and analyze how professionals attached to the social services and public housing companies in Gothenburg explained that homeless women with substance abuse were excluded from accommodation on the open housing market. The qualitative approach included ten interviews with eleven professionals in Gothenburg. The theoretical framework consisted mainly of Bourdieu's analytical concepts of field, doxa as well as social, economic and cultural, alongside symbolic capital.
Utveckling av en dynamisk Simuleringsmodell av en skotare
The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

Är objektiva moraliska värden möjliga utan Gud? : en teoriprövning av Moralens Landskap
What drove me to write this paper is the will to examine if there is a philosophically and scientifically viable alternative foundation for an objective morality other than what we like to refer to as "God". The American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a scientific ground.
Implementering av affärssystem : - en granskning av Dentatus införande av MicrosoftDynamics AX
Affärssystem har de senaste åren uppträtt som kärnan i framgångsrik informationshantering och agerat ryggrad i många företagsorganisationer. Införskaffandet av rätt system är en komplicerad process, men ofta avgörande huruvida en framgångsrik implementering skall fortskrida eller inte. Perioden då företaget inskaffat ett system till den definitiva utrullningen är således ofta en krävande och kostsam process för organisationen. För att avgränsa begreppet affärssystem har vi valt att använda Gartner Groups definition: ?A collection of applications that can be used to manage the whole business?.

Konsumentproduktion av mjukvara
Uppsatsen handlar om konsumenter som producerar produkter som sprids och konsumeras av andra konsumenter. Fenomenet kallas i denna uppsats för konsumentproduktion och jag har inte hittat bra litteratur om ämnet. Dagens allmänt citerade marknadsföringslitteratur som studerats i denna undersökning nämner inte konsumentproduktion som sprids till andra konsumenter. Den litteratur om Open Source som studerats nämner konsumentproduktion, men terminologin för konsumentproduktion är oklar och fokus sätts aldrig på ämnet. Litteraturen i motsats till denna uppsats nämner dessutom bara en mycket speciell och extremare variant av konsumentproduktion som produceras av högt kompetenta programmerare; istället för att som i denna uppsats ge bilden av att även andra konsumenter med andra eller ingen kompetens alls utför konsumentproduktion.
