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.
En agil arbetsmetod för utveckling av ett leverantörsstöd
This thesis was made possible by the company Verendus system AB, which is the leading developer of dealership management systems in the caravan and camper market. The goal of the thesis was to create a statistics module for a new producer system envisioned by Verendus. The new system is aimed at manufacturers and importers of caravans and campers, with the goal of enabling its users to create more effective production lines. By providing statistical data to mentioned users they will be able to predict market trends and customize their production lines accordingly. Today such software does not exist which leads Verendus to think that its arrival would lead to a success on the market.Before the development and design of the producer system began, a new agile method had to be developed, MAM (Minimum Agile Method).
Systemutveckling i praktiken - konsten att tillmötesgå den okända användarens krav
ABSTRACT
System development has become more and more concentrated on development for the
Web and this has resulted in larger target groups. It will most surely continue
to be so considering that the Web will be the infrastructure of business and
services in the future. A big target group involves that the owner of a system
can earn a lot of money from the paying users, but that assumes that the system
can meet user needs. If a system on the Web does not satisfy the user?s demands
then they will use the competitor?s system instead because it is only a
mouse-click away.
Beslutsstöd för underhåll av järnvägsfordon - En studie om utökat användande av hjulskadedetektorer i det proaktiva underhållsarbetet
Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.
Apputveckling : En studie av motsättningar mellan design- och användningspraktiker ur ett verksamhetsteoretiskt perspektiv
We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.
Simulering av energieffektiviserande åtgärder för små- och flerbostadshus : Möjligheter för JM:s hustyper att uppnå passivhuskonceptet vid nybyggnation
The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.
Förväntningar och erfarenheter kring skolledarskap : en jämförande studie ur lärarperspektiv
Background: There have been several reforms within the Swedish educational system since the 1960´s, not only within the elementary school but also within the teachers? education and the school leaders´ educational program.Aim: My aim with this study is to explore if teachers´ expectations and experiences of school leadership have changed since the many educational reforms began in the 1960´s.Method: For this study I have a used a comparative design. By making qualitative interviews with five teachers born in the 1940´s and five teachers born in the 1980´s I have then analyzed the result.Result: Regardless of the 40 years of age difference and the multiple reforms within the educational system in Sweden the result shows that the teachers in this study did not have any clear expectations on their school leaders as they started their careers..

I vår produktion har vi tagit fram ett system för order- och lagerhantering, med vikt på realtidsuppdateringar, åt en extern mottagare där infrastrukturen inte hängt med i företagets utveckling. Vi valde detta projekt i syfte att bredda våra kunskaper inom både programmering och projekthantering. Denna slutreflektion tar upp den förundersökning vi gjorde för att kunna besluta om vilka verktyg vi använde i utvecklingen, den tar även upp vårt sätt att hantera och planera projektet. Under projektet har vi arbetat med en egenutformad arbetsprocess vilken även beskrivs här. --- Our production has been to design a system for ordering and supply management with emphasis on realtime updates to an external recipient, where the infrastructure has not kept pace with the development of the company.
Beräkning av koldioxidutsläppet från bostadssektorn i Stockholms län
During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.
Mobilapplikationsutveckling med en användarcentrerad designfilosofi ? enligt ISO 9241-210
Marknaden för smartphones har vuxit stort under de senaste åren och även utveckling av applikationer till dessa. Då utveckling av applikationer för smartphones skiljer sig från traditionell utveckling så passar inte traditionella utvecklingsprocesser för utveckling till smartphones på ett optimalt sätt. Denna studie undersöker mobilapplikationsutveckling med fokus på användbarhet. Då det råder brist på systemutvecklingsprocesser för mobilapplikationsutveckling så vill denna studie utvärdera ISO standarden ?ISO 9241-210 ? Användarcentrerad design för interaktiva system?.
Design från intressen : Hur intressen kan påverka utformningen av ett stridsfordon till att framstå som vänligt sinnat och eget
Detta examensarbete behandlar hur individers mål, ståndpunkter och attityder kring ett föremål kan användas i föremålets design för att individerna lättare skall kunna identifiera sig med föremålet ifråga samt betrakta det som eget och/eller vänligt sinnat. Denna metod för design av föremål testades genom design och modellering av ett stridsfordon, vilket sedan utvärderades i en enkätundersökning tillsammans med ett redan existerande västerländskt stridsfordon. Syftet med undersökningen var att undersöka vilket av stridsfordonen som målgruppen ansåg vara lättast att identifiera sig med/framstod mest som egen.Undersökningen visade att stridsfordonet som designats med tanke på målgruppens mål, ståndpunkter och attityder också i större utsträckning upplevdes som vänligt sinnat/egen..

BeAKKta - ett kommunikationshjälpmedel som möter behoven av djupare kommunikation hos personer med autism
A vulnerable group in society is people with ASD (autism spectrum disorders) or
autism. This group seems to increase, mainly due to genetic factors but also
environmental problems. Medical research has accelerated in the U.S. and
Europe. The biggest problem for people with disabilities is the inability to
communicate, both verbally and socially.
Metoder för kartläggning och analys av nätförluster i lågspänningsnät
An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.
