The task for the machine was to facilitate the process of making openings for testing in the company?s other equipment. Researches on different methods of cutting, types of automatization and possible designs were made. To implement the project a design and construction from the base where chosen.

This Masters thesis is made as the first of two visitor surveys of three urban forest areas. These areas are; Skutan recreational area in Haninge, Ugglevikskällan on Norra Djurgården in Stockholm and the Paradiset Reserve in Huddinge. The study is made in cooperation with the managers of the three areas operating within the European Union Life Project regarding Urban Woods for People. The goal has been to collect data through studies of visitors and close by residents in the three areas. The results are to be used as primary values for the follow-up as well as a basis for managerial decisions. The interviews and surveys are also constructed in a fashion so that they can be used for the follow-up study. For the Skutan recreational area the mode of contact was by sending forms to the nearby residential areas.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

To get the maximal output of your exercise in gym machines, there are different factorsto be considered. For example the strength of the muscle varies dependent on the positionof the muscles. To get the best results of the exercise the load has to reduce and increaseat specific positions.This study was made in cooperation with Caretaker Scandinavia AB, a company forsales, marketing and development in health care. They are general agent for Nordic Gymwho works with manufacturing of equipment and machines for gym and fitness.The aim of this study was to generate a method of measurement to evaluate and controlthe biomechanics of Nordic Gym´s workout equipment. A protocol for an ergonomicanalysis on the equipment has also been elaborated.One of the methods to measure the biomechanics was to measure the torque through thewhole movement.

Rapporten är en utvärdering av möjligheten att generera elektrisk energi från fjärrvärme med Seebeck-effekten och görs på uppdrag av Skellefteå Kraft. Kursen är examensarbete för högskoleingenjörsexamen i Elkraftteknik, 5EL210 vid institutionen tillämpad fysik och elektronik på Umeå Universitet under vårterminen 2014.En termoelektrisk generator fungerar enligt Seebeck-effekten och genererar en elektrisk spänning som är linjär mot temperaturskillnaden mellan sina två metallytor. För att få en temperaturskillnad så krävs ett kylmedium vilket skapar ett värmeflöde från den varma energikällan till kylmediumet. Utan kylmediumet så kommer temperaturerna gå mot samma värde. Ett kylmedium kan till exempel vara snö, markgrunden eller vattenradiatorer.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

AbstractThe purpose of this paper is to examine how the population living in Christiania considers their residential area in relation to the surrounding society, and why you as an individual choose to live there. We have used the qualitative method and we have performed interviews with a total of six persons. We have used Tönnies two notions regarding gemeinschaft and gesellschaft, and Goffmans theory about stigma. We choose these theories because we thought that they were most relevant for our study. Our question at issue is: Why does a person seek to live in an alternative society, with different norms in comparison to the majority society? Through our interview persons we learned their stories and their opinions considering their residential area and we concluded that Christiania differs from the remaining society in several ways.

Dagens bilar är gjorda för långa resor med högt ställda krav på bekvämlighet och komfort. Studier har visat att de flesta resor som görs i Storstockholm är korta, och därför är kravet på prestanda och komfort minimalt.Syftet med detta projekt var att ta fram ett enkelt pendlingsfordon som del av ett hyrsystem. Användaren hyr fordonet vid en station och lämnar av den vid en annan.Fokus har legat på att utveckla en parkeringslösning som spar plats. Att bygga parkeringsstationer i förbindelse med befintlig kollektivtrafik är svårt, och marken i Stockholm är både begränsad och dyr.Efter en omfattande förstudie fastställdes en kravspecifikation som låg till grund för den fortsatta konceptutvecklingen.Det slutgiltiga konceptet blev Electric Commute Vehicle, ett elfordon avsett för personlig transport och pendlingstrafik. Fordonet döptes till X-traffic (Cross-traffic) och har utrustats med en unik parkeringslösning där fordonen packas likt kundvagnar.

The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

Företagsförvärv är en vanligt förkommande strategi för tillväxt och verksamhetsutveckling. Hur den förvärvande parten hanterar själva integrationsprocessen av den uppköpta verksamheten är av avgörande betydelse för möjligheten att realisera önskade samordningseffekter. Integrationsprocessens framgång är i sin tur beroende av de anställdas upplevda välmående och belastning under processen. Syftet med undersökningen är att studera hur hårda integrationsansatser påverkar de anställdas upplevda välmående och belastning i samband med ett företagsförvärv. Undersökningen studerar också huruvida det existerar samband mellan anställdas upplevda välmående och deras arbetsbelastning, samt hur upplevelserna skiljer sig åt mellan olika faser i integrationsprocessen.

I samband med Transportstyrelsens införande av utökad B-körkortsbehörighet öppnades nya marknader för släpvagnar anpassade för transport av tävlingsbilar, verktyg och reservdelar. Sådana släpvagnar går att införskaffa sig idag på den svenska marknaden, dock är dessa endast anpassade för körkortsbehörigheten BE. Detta projekt utförs på uppdrag av företaget Fredrik Wagner AB, ett företag som designar och konstruerar transportband. Syftet med arbetet var att undersöka och utforska möjligheten för implementering av en ny släpvagnsmodell på den svenska marknaden. Målet med arbetet var att utveckla ett släpvagnskoncept anpassat för utökad B-behörighet, och därefter designa en CAD-modell av konceptet.Information om bilsporten och marknaden samlades in för att definiera och förstå problemet bättre.

The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.
