Lokalisering av vågkraftanläggningar : Metodutveckling med GIS och fallstudie Bohuskusten

In this thesis work a Geographical Information System (GIS) based methodology to identify locations suitable for the installation of wave energy converters has been developed. Parameters of importance have been identified and a GIS-database has been set up, containing data about the marine environment. In a case study of the Swedish west coast the methodology has been applied, resulting in a number of maps showing possible areas. The results show that large areas are suitable for installation of wave energy converters, from a technical and economical point of view. When consideration is taken to other interests in the area, such as navigation, fishing and environmental protection, the size of the suitable area diminishes considerably.

Attraktiv arbetsgivare : en jämförande studie i tre oilka organisationer

This study was carried out at Luftfartsverket (LFV Group, SwedishAirports and Air Navigation Services), AstraZeneca and Svenska Spel. The purpose of the study was to examine and compare how these companies work towards becoming, and maintaining to be, an employer of choice. Facts were sought about the companies and their work to become an employer of choice.To get a discerning and profound picture, a qualitative method with semi-structured interviews with twelve key persons in this work was conducted. The method Interpretative Phenomenological Analysis (IPA) was used for analysis.The results showed that an amount of factors have an input on how attractive the employer is. Common were compensation and benefits, competence development, leadership, information and health-related activities.

Webbplatser för alla : Om tillgängligheten på folkbibliotekens webbplatser

The aim of this master thesis is to study if the websites of the Swedish public libraries are accessible to all people. According to the library law all people must have access to the public libraries and their information services. Today, when the Internet is one of the largest sources of information, it is important that all people, including those with different kind of disabilities, children, elderly, immigrants and people with old technical equipment, have access to the public libraries websites.We have in this study considered the graphic user interface, the language, the structure and the navigation possibilities at ten public library websites. We have from a checklist of our own, based upon the opinion of different experts such as Jacob Nielsen and Tommy Sundström, investigated the websites.The main finding of our study is that the websites are generally accessible even thou we found a lack of accessible for immigrants. Most of the websites had some pages in English, but none hade all pages in this language.

Uppföljningsverktyg för analys av användarloggar

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Ekonomi i Passivhus : En studie av två verkliga byggnader

The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

Hjälp! Vem tog min GPS? : Studie av redundanta metoder i integrerade positioneringssystem

Möjligheten att bestämma sin position med ett par meters noggrannhet varhelst på jordklotetman befinner sig har med tillgången till GPS blivit möjligt för alla som investerar i en GPSmottagare,således även Försvarsmakten. GPS har dock begränsningar som gör att tillgångentill tjänsten kan blockeras med enkla medel av såväl systemets ägare som andra. I Försvarsmaktenfinns det anvisningar inför anskaffandet av satellitpositioneringssystem som gör gällandeatt detta endast skall utgöra ett komplement till andra redundanta metoder. För militäraändamål har GPS ofta integrerats tillsammans med tröghetsnavigering där de båda metodernakompletterar varandra. Utan tillgång till GPS kommer positionsfelet i ett sådant system efteren kortare tid växa sig stort.

Interaktionsloggning i Scania Interactor

Scania provides a fleet management system for hauliers who want to control their fleets in anefficient way. The system includes an onboard computer with touch screen called ScaniaInteractor where the driver can access GPS navigation, order support, message service and otherfunctionalities. The purpose of this thesis is to develop a concept for logging the user interactionon the Interactor and analyze the result which enables further development and optimization ofthe interface.A demonstration application is designed, implemented and tested for the purpose of showing thepossibilities and difficulties with logging of interaction. The result shows that logging is quiteeasy to implement and that the amount of produced data is small and therefore not expensive totransfer via GPRS to a central server where searching and analysis can be done. On the otherhand, the biggest challenge lies in the analysis and interpretation of the logged data and to applyit to the development of the interface.

Estimering av GPS pålitlighet och GPS/INS fusion

The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning.  An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.

Barnsligt lätt att hitta rätt? En observationsstudie om hur barn navigerar mobila applikationer

Children?s use of mobile devices is constantly increasing and has become very popular withchildren as young as toddlers. Schools in Sweden have made large investments to expand theuse of information technology (IT), and the use of mobile devices in preschools is already acommon support tool for learning. Children?s use of IT is a relatively new phenomenon,which means that is it also a relatively new area of research.

Användartester inom webbutveckling : Är användartester nödvändigt vid utveckling av webbplatser?

The aim of this study is to get a deeper understanding about user tests as well as answer the question about if testing for users is necessary at all times. I've done a comparison between what the literature says, and what a company says, about testing. The tests that's been in focus in this study is prototyping and card sorting tests. Prototyping aims to give the developer feedback about the design and check if there are any obvious problems with the design. A card sorting test can be used to get input about how information architecture should be constructed.

Utvärdering av Artificiella Neurala Arkitekturer För Navigering

Den klassiska approachen till navigering innefattar att agenten håller en intern representativ modell av omgivningen. Denna approach har emellertid många nackdelar, speciellt för dynamiska miljöer. En modernare approach är att förlita sig på den faktiska omgivningen istället för en modell av denna. Detta arbete presenterar en undersökning av navigeringsproblemet och hur väl det löses av agenter vars kontrollmekanismer utgörs artificiella neurala nätverk. Tillförlitligheten hos de två neurala arkitekturerna Extended sequential cascaded network och Self-organized recurrent network bestäms genom experiment.
