Utveckling och konstruktion av dämpare och låssystem för vågkraftverk

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.

Intelligenta System

Intresset för agenter som forskningsområde är någonting relativt nytt. Agenter i sig är en naturlig del av Artificiell intelligens men det är först på senare tid som de hamnat i fokus. Begreppet agent har spridit sig som en löpeld utanför AI-forskningen och kan hittas i många andra områden. Vad detta intresse för agenter kommer ifrån kan debatteras men det är troligtvis dels en följd av att internet visat hur kraftfullt ett distribuerat system kan vara, och att agenter och botar bokar våra biljetter samt söker igenom webbsidor åt oss.Arbetets huvudfråga är att undersöka hur ett intelligent system (för värmedistributionen i ett hus) kan uppnås genom att koppla ihop ett antal agenter med begränsade funktionalitet och distinkta uppgifter. Intelligensen i systemet ska uppnås genom samverkan mellan de olika agenterna.

Fågel fisk eller mittemellan?

The project is a thesis which intends to strengthen the form language and increase the user friendliness of an International Moth. This is a single handed dinghy with only one sail. It sails on two hydrofoils and receives a very high speed compared to its size, and are therefore often referred to as ?the Formula One on water ?. The result is a new concept where the aerodynamic forces have been used to stabilize the boat and relieve the hydrofoils.

Based on a life story interview the study aims at analyzing perceptions of procedures to enhance special needs users? influence. The method used in this study was a qualitative research approach as an overall approach in order to use a narrative method where life history is the method. The focus has been to study a part of an individual life history - a specific domain in the life of the interviewee?s working career.

Systemarkitektur och implementering av standardsystem : En fallstudie vid Linköpings universitetsbibliotek

The use of ERP in organisations is very popular and many companies have embraced this paradigm without really questioning why. Problems therefore often arise and cause high costs which is a result of poor planning. The paradigm also has its origin in the traditional architectural design that creates a system that has difficulties to adapt to organizations that are constantly evolving. The purpose of this study is to provide a different view of how IT-systems can operate within an organization and show how standard systems can be structured. We emanated from a case study at Linköping University Library, where we studied the implementation and integration of a standard system called Symphony.

Är det svårt att hitta i en mobitelefonmanual? : En kvalitativ fallstudie om informationssökning och användbarhet

This master thesis states the following questions: Is it easy or difficult to retrive information from a mobile phone manual? How can the search process be described among user for a mobile phone manual? What similarities and differeces can be identified between users? Arhe there any variables that affect search performance such as reading skills or technical domain knowledge? Eight mobile phone users participated in an empirical observation and the scope was to find information in a paper version of a mobile phone manual according to given tasks. The results shows that some users has problems to retrieve information due to that the correct page in the mobile phone manual could not be located. The results show that the user is using several search strategies, for example the table of contents and the index, when trying to locate information. The results also revel that the user initiates multiple search steps before the correct information can be located.

Övervakningssystem för båtelektronik

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

Museum på webben - en undersökning om användbarhet och åtkomst

The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.

Tredimensionell sensorscanner

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

Ditt liv genom andras ögon : En kvalitativ studie om yngre kvinnors personliga integritet på Instagram

Since social media is used more today than just a few years ago, it is easier to share our lives to the public in just a few seconds. Social media is easily accessible on smartphones, tablets and computers which allow us users to use them whenever we want.Instagram is an example of a very popular social media today. In this paper we focus on how younger women think about their privacy when using and publishing pictures on Instagram. We have been using a qualitative research method in which ten people were interviewed. All respondents agreed that privacy is important when publishing pictures or videos on Instagram, but there were also some differences between users with public and private accounts.

Läsförståelse eller litterära föreställningsvärldar : Litteraturpedagogisk diskurs inom gymnasieämnet engelska

Reading and analyzing literature has a long tradition of being an essential part of the teaching of English in Sweden. As the offers of entertainment have increased in popular culture with the introduction of computer games, internet and other media, interest in reading novels has decreased. Literature is still a compulsory part of English teaching and the question is how teachers of today use literature and what kind of literary instruction they use.The aim of this study is to explore and discuss the literary instruction discourse in pedagogical texts, lessons, created by and for English teachers of Swedish Upper Secondary Schools. The lessons have been collected from the site lektion.se, where teachers are able to share knowledge and lessons. The study uses an analytical method based on Norman Fairclough´s Critical Discourse Analysis in order to analyze the lessons.

Re-Design av Dagens ETC

The project is about making a Re-Design of the Swedish Socialistic Newspaper ?Dagens ETC?. The background to the project is my search for commitment when I work with a specific customer or project and how importantthat commitment are?The project was from the beginning split up to three different phases. The meaning of the first phase where to make a re-design mainly based on a interview with Johan Ehernberg, the chef editor on ETC.The second phase was a design totally made of my own idea and creative view as a Graphic Designer.I had in mind to make the third phase based on the result of the first two phases.During phase one and two I reconsidered and decided to skip the third step and put more effort in to the two first ones.
