This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.

Svanen är en av världens ledande miljömärkningar och firade nyligen 20 års jubileum. Det har under ett antal år varit möjligt att förutom produkter även svanenmärka tjänster och verksamheter, så som exempelvis restauranger och hotell. För att miljöarbetet inom en verksamhet ska fungera så bra som möjligt är kommunikationen i denna av yttersta vikt. Det har inte utförts några kända studier kring hur kommunikationen på Svanenmärkta hotell fungerar vilket är motivet bakom denna studie. Det finns en misstänksamhet i samhället mot miljömärkta varor och greenwashing har blivit ett allt vanligare begrepp, vilket innebär att företag utnyttjar miljömärkningar för att få ett bättre anseende på marknaden och inte för att egentligen gynna miljön.

Our ambition is to take care of current qualities of today's wallet and improve where it is possible so that can be replaceable with the digital wallet..

Volvo Wheel Loaders är en av världens ledande tillverkare av hjullastare. Examensarbetet är utfört på huvudfabriken, som ligger i Arvika. Bakgrunden till projektet är att det finns en vilja från ledningen att införa statistisk processtyrning (SPS) i produktionen. Viljan kommer av krav i kvalitetssystemet och att framtida investeringar i automatiserad häftsvetsning kommer att kräva större precision i produktionen. Examensarbetets syfte var att inleda och underlätta ett införande av SPS.

Problem: The relations between first and second tier suppliers within the automotive industry have changed drastically during recent years. Previously involving the supply of simple components, today the relation involves collaborative product development of complex subsystems. The situation is rather new for the actors, hence there are a number of problems that act as restraints for the collaboration. In order to come to terms with these problems, it is important to determine the underlying causes. Purpose: The purpose of this thesis is to make a survey of the main problems in the collaborative product development between first and second tier suppliers within the Swedish automotive industry.

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Flamskyddande kemikalier används idag inom en hel del olika områden. Ett stort område är textil, där hemtextil är dominerande. Det finns en mängd olika typer av flamskydd på marknaden. Alla har till uppgift att sakta ner brandförloppet eller helt förhindra att en brand uppstår. De halogenerade flamskydden är de mest effektiva men har många kopplingar till miljöproblem.

Förmågan att organisera, styra och samordna allt mer internationella företag blir allt viktigare. Dagens marknad kräver att organisationerna är flexibla för att kunna svara på markandens krav. Såväl organisationsutvecklare som strateger har varit nödsakade att tänka i helt nya banor, vilket varit vitaliserande för synen på utvecklingsfrågor. Chefer måste bli ledare för att ?förränta? människokapitalet.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

The aim of this study was to review scientific articles to evaluate which nursing treatment are in use to ease problems such as dysphagia, mucositis and xerostomia and its efficiency. The method was a literature review in which the scientific articles where found in the database PubMed. A total of sixteen articles where included, these articles where analyzed based on their quality and contents. The result showed that electrical stimulation and rehabilitation was used against dysphagia, they both had a doubtful effect. Mouth washes was commonly used to reduce mucositis; triclosan mouthwash, benzydamine mouthwash, sacralfate mouth wash, povidone-iodine and salt-sodium mouthwash showed effect.

In this project a washing station has been constructed for Albany International AB. At present, there is no existing system to clean the dirty pipes that are coming back to the company.The work followed the product development process, and it started with the requirements list. This was followed by brainstorming, evaluation and completion.The result was a concept for de present time and one concept for the future.The present concept is intended to be built immediately. This is an adjustable bench with sliding bearings to facilitate the work. The actual cleaning is done with a high pressure washer that uses hot water.

In this essay a conclusion about the way female characters are portrayed in fantasy novels will be attempted through an analysis of one selected female character from each selected novel. The works that have been chosen are; J.R.R. Tolkien?s The Lord of the Rings, Robert Jordan?s The Eye of the World and A Game of Thrones by George R.R. Martin.The analysis will be done with the help of examples and theories from both feministic criticism and gender studies.

This thesis serves to examine how manufacturing SMEs consider outsourcing. Furthermore, we aim to identify the main characteristics and patterns for these types of companies that can explain their rationale in such a decision. The chosen method for this thesis is abduction and selected research approach is multiple case studies. Seven case studies have been conducted at EAB AB, Esbe AB, Hörle Automatic AB, Pelly Industri AB, SGV Industrier AB, Swede-Wheel AB and Wulkan AB. Our findings have illustrated that although traditional outsourcing theory provides a good platform for explaining the rationale behind outsourcing decisions in SMEs, we have identified additional considerations that SMEs, operating as 2, 3 or 4-tier suppliers towards OEM-corporations, make.

Idag är det möjligt att modellera de hydrauliska och mekaniska systemen hos en hjullastare. Det går även i viss omfattning att simulera omgivningen samt de förarkommandon som krävs för utförandet av en önskad uppgift. Däremot är det enda sättet att få reda på hur en förare kommer att uppleva maskinen, dess körbarhet, att bygga en fungerande prototyp och be en förare att testa den.Syftet med det här examensarbetet var att hitta en korrelation mellan förarens bedömningar och mätdata insamlade från en hjullastare under körning. Resultaten är sedan tänkta att användas i framtida simuleringar. Olika hjullastare testades av en grupp provförare och deras subjektiva bedömningar såväl som mätdata från hjullastarna samlades in.Slutsatsen är att det går till en viss del att förutsäga körbarheten från insamlade data om förarens körstil är känd.
