I wanted the project to display a possible vision of the future of transport in winter environment with sustainability in focus. Snowmobiles mostly run with oil smoking two stroke engines which pollute the environment. Smell, noise, high toxic output and bad fuel economy. Can it be solved with alternative sources of energy? How will an alternative source of energy change the conditions for the pro
Studiens syfte är att undersöka sambandet mellan barns förmåga till perspektivtagande och deras kognitiva respons på jämlikars affektiva upplevelser. 90 stycken andraklassare respektive 119 stycken fjärdeklassare deltog i studien. Svarsfrekvensen var 83 %. The Interpersonal Negotiating Strategies Interview (Schultz et al., 1989) användes för att mäta deltagarnas förmåga att särskilja och koordiner
Uppsatsens titel: ”Men scannern är ju dammig!” – En studie om självscanning som kvalitetsskapande aktivitet Kurs: Kandidatuppsats, 15 hp, VT 2009 Författare: Louise Andersson Torson, Åsa Hellqvist, Helena Olsson Handledare: Christer Eldh, Veronica Åberg Syfte: Syftet med denna uppsats är att undersöka om, och i så fall på vilka sätt, införandet av självservice skapar kvalitet ur ett kundperspektiv
Det här examensarbetet handlar om datorbaserade hjälpmedel som är licensierade med en FOSS-licens (Free and Open Source Software). Frågeställningen är: ”Hur kan utbudet av datorhjälpmedel för personer med synnedsättning och/eller läs- och skrivsvårigheter berikas genom spridandet av program som baseras på fri programvara och öppen källkod?” Arbetet bygger till största delen på intervjuer av pers
Multimodal user interfaces or interfaces that involve the user with several senses could greatly improve usability and accessibility. A mobile phone contains several hardware technologies such as accelerometers, touch screens and vibrators that can be used to support a multimodal user interface, but these capabilities are seldom used. In this thesis multimodal interaction and how two-dimensional
Målet med examensarbetet har varit att skapa ett grafiskt gränssnitt som markant underlättar användandet av mobiltelefon för synsvaga personer. Utvecklingsarbetet har varit en iterativ process där de val som gjorts så snabbt som möjligt har testats mot användaren och i vissa fall även mot personer som anses vara experter vad gäller interaktionen mellan mobiltelefon och användare. Examensarbetet h
National parks have been a common way of protecting biodiversity, and the model has been spreading around the world since the first national park of the world, Yellowstone, was established in the U.S. more than 130 years ago. However, the concept of national parks has also been criticized, for example as representing a North-perception of the environment that is imposed on the South. The purpose o
There is a need to make the front and specially the window on the phone more resistant to scratches and marks. The main reason for this is that scratched windows will spoil the appearance of the complete phone and customer will perceive variations on visual aspect that could make them change the brand. The improved scratch resistance for the front will also improve the yield during the production
I föreliggande uppsats studerar jag en avhandling, De Erico IX sive Sancto, från 1700-talet. Avhandlingen handlar om Erik den helige och författaren heter Petrus Schvantesson Höök. Den framlades vid Uppsala universitet 1712 under professor Fabian Törner. Min undersökning är en jämförelse mellan den medeltida Erikslegenden och ovannämnda avhandling, där jag koncentrerat mig på att undersöka innehå
Ownership is said to be the key principle of efficient aid and crucial for a successful outcome of the Poverty Reduction Strategy (PRS). However, it is a contested concept and has been criticised for being vague and contradictory. This study discusses problems of developing cooperation and aid, with focus on the concept of ownership, and tries to define ownership and assess the state of ownership
The purpose of this Master’s Thesis was to examine different usage applications for animations and to develop one or several animated products for Sony Ericsson Mobile Communications AB. The overall objective was to develop an animated tool for information purposes and to investigate different interesting fields of application for the animated products. The goal was also to show the procedure of c
When developing a truck it is of critical importance that the brake system is reliable and effective. When testing new trucks or brake systems you need to collect as much data as possible. One important measurand when you evaluate a pneumatic brake system is the stroke of the actuator. This master’s thesis has two goals; one is to develop a device for measuring the stroke of a pneumatic actuator m
utföras med befintliga materialmodeller. Vid framtagning av en ny materialmodell för wellpapp behövs något att verifiera mot för att kontrollera att egenskaperna stämmer överens med verkligheten. För detta ändamål utvecklas inom detta examensarbete en infästning för dragprov av wellpapp. För att kunna utvärdera de olika framtagna förslagen har beräkningar i ANSYS utförts för att kontrollera hur sp
Problem Tetra Pak R&D AB needs to find working methods that can be Formulation useful in their effort to develop a more formal, efficient and effective engineering design process. Objective The overall objective of this Masters’ thesis is to present a formal description of the existing engineering design process for the Department of Machine Technologies at Tetra Pak Research & Development
This master thesis was conducted as a project for Faiveley Transport Nordic AB. The company’s main operations are development and assembly of complete brake solutions, brake products, wheels and couplings for rail vehicles. The background of this project was a well thought out idea of a new generation of friction brakes. The idea of V-brake is to complement or replace the block brake. A problem wi
The project started with a section called Clarification Of The Task. The purpose was to investigate how big of a problem domestic flooding is and what the cause is. This was done by gathering information from different organizations and companies. Once we knew the problems we tried to understand the water systems that are the main failure in households. Now when we know the problem and understand
For many years the benefits of using stockings that exert a pressure on the legs, to prevent and treat a number of health conditions, have been well known. For just as many years carers and caretakers have been struggling to put on these stockings onto the legs. The high compression strength of the stockings makes it very difficult to put them on the way one does with ordinary stockings. Today, me
The costs for producing machines have increased a lot in the latest years. For Presona this has meant that production costs for their main waste compactor needed to be cut in order to keep the compactor in their production line. The waste compactor was initially developed sometime in the 1960s when the price for construction materials and assembly allowed Presona to develop the compactor using a t
Interference fit assembly is a state-of-the-art technology for mounting cylindrical shafts into bores. Due to its extreme cost-efficiency it is used even in high-tech applications such as one of Bosch’s gasoline flow controllers. The picture below shows the anchor-needle connection. Due to electromagnetic incitation the assembly oscillates over 55 times per second. In order for the assembly to wit
