Automatiserad inlärning av detaljer för igenkänning och robotplockning
Just how far is it possible to make learning of new parts for recognition and robot picking autonomous? This thesis initially gives the prerequisites for the steps in learning and calibration that are to be automated. Among these tasks are to select a suitable part model from numerous candidates with the help of a new part segmenter, as well as computing the spatial extent of this part, facilitating robotic collision handling. Other tasks are to analyze the part model in order to highlight correct and suitable edge segments for increasing pattern matching certainty, and to choose appropriate acceptance levels for pattern matching. Furthermore, tasks deal with simplifying camera calibration by analyzing the calibration pattern, as well as compensating for differences in perspective at great depth variations, by calculating the centre of perspective of the image.
Utvecklingen av det digitala folkbiblioteket - När visionerna liknar verkligheten
As the way of communicating and accessing information has changed radically over thepast decade so has the way the public libraries operate to reach the citizens. In thesetimes the demands of what a public library should be and offer the visitors havechanged. One should have the option to access the digital public library at any givenhour of the day, from anywhere in the world and at least have the same possibilities ofinformation as the visitors at the non-digital, "real" library.In this Master's thesis we will analyze and discuss the condition of the Swedish digitalpublic library of today, 2006, and the forward thinking work with the issues ofdevelopment in this matter. In order to do this we set out to examine the attitudetowards the public digital library among the staff at a small number of Swedish publiclibraries and their supporting institution, the county library. Moreover, the attitudesdefined have been compared to the actual status of the services and medias at the publiclibrary websites.In conclusion, we have detected a certain standardization of what the digital publiclibrary consists of today.
Swedish Meats : motiven bakom försäljningen av kooperationen
In 2007 Swedish Meats, the dominant Swedish meat-producers cooperative sold its slaughtering and processing industry. The goal of a producer cooperative structure is to create value for members through vertical integration, and to strengthen members? market position. When Swedish Meats sold the slaughtering and processing components, it ceased in some respects to serve the function of a cooperative. This is a lost opportunity for both members and non-members, because Swedish Meats as a functioning cooperative could have exploited its dominant market position to positively effect producer?s prices.
UV-tork - analys av drift :
The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.
Den digitala strategin : En rapport om arbetet med en digital strategi för ett litet, nystartat företag
Social media, such as Facebook, Instagram and Twitter, have become popular platforms for social communication, and, increasingly, also important channels for business marketing. For a business intending to use social media for marketing, however, developing a strategy and building a trademark can be a challenge. This report describes how a small, newly established business enterprise can develop a digital strategy with clear goals and practical guidelines. The report describes a digital strategy for Gelato Scarfó and shows how this strategy is made concrete through a set of guidelines. The guidelines develop a trademark for identification and loyalty, and give advice on how new materials can be made consistent with the trademark..

Äldre och den nya världen : En kvalitativ innehållsanalys av medieanvändande hos den äldre generationen
AbstractTitle: The old generation and the New World - A qualitative content analysis of media usage of the older generationKeywords:Digital natives, digital immigrants, diffusion of innovation, content analysisThis study has its focus on how the older generation looks at today's media society and the use of today's media. Through a method of qualitative content analysis based on questionnaires, the aim is to examine what the older generation thinks about today's media, how they use them, and whether there are differences in groups according to age and previous work.The study selected theories bases on Marc Prenskys idea of ??digital natives, digital immigrants and Everett M Rogers book on "Diffusion of Innovation". These theories take up the difference on digital natives and digital immigrants and the spread of new technological ideas takes place through communication over different channels in time among causes people in a social system.The result of the study shows that many older people are good at making use of today's media, but also that many may feel alienation of today's media society. Development has proceeded rapidly in recent years and for the older generation it's sometimes hard to keep up.The conclusion of the study is that the older generation may need more help to discover how today's media can facilitate everyday life and enrich it with more communication despite the fact that it takes place through a screen..
Kontorslandskap och sensory-processing sensitivitet : Vilken betydelse har de för välbefinnande, hälsa och arbetsvillkor hos designstudenter?
Kontorslandskap är en vanligt förekommande kontorsdesign och fördelar och nackdelar med att arbeta i sådan miljö är oklara. Syften med denna studie var att a) undersöka hur individer upplever att arbeta i kontorslandskap och vad det kan ha för konsekvenser för hälsa och arbetsvillkor, och b) undersöka deras grad av känslighet i förhållande till kontorslandskap, hälsa och arbetsvillkor. Studenter vid Beckmans designhögskola deltog i studien genom att fylla i en enkät. Resultaten visade att upplevelse av kontorslandskap var relaterat till anspänning av arbete och arbetstillfredsställelse men inte till sensory-processing sensitivitet vilket är delvis i linje med tidigare forskning. Att uppleva kontorslandskap som positivt kan kopplas till högre arbetstillfredsställelse och lägre anspänning av arbetet.
Digitala verktyg - Hjälp eller stjälp: Fyra lärares tankar om digitala verktyg i musikundervisningen i åk 6-9
This study shows the thoughts, hopes and wishes of two male and two female music teachers, in grades 6 ? 9 from four different cities of Sweden. The emphasis lays on usage of digital tools. As the schools now stand before lots of changes in its curriculums; the use of digital tools was the main thing that caught my interest. How has the schools interpreted what this means? What does this mean in terms of purchases for the schools? We already know that many schools are lacking proper facilities to conduct music lessons so this ads on even larger needs.
Scandinavium : Sveriges största inomhusarena
Ever since the development of the pc and their software, in the early 80´s,architects way of work have changed a lot. Nowadays most of the architectspresent all their works digitally and not with hand drawn material, as they didbefore the pc boom.Digital visualisation technique pushes the limits, when it is about presentingarchitecture projects virtual reality.This report studies how digital visualization technique is used among thearchitects today.Together with architects from ABAKO architect firm in Gothenburg, Sweden,interviews has been made to give answers about what they think about digitalvisualization technique. What are the opportunities, advantages- anddisadvantage with this digital technique?The answers from the architects, together with work that has been done withdigital visualization technique in a project called Project Sofiedal, shows thatthis technique has big opportunities when it comes to create nice looking VRpresentations. The result in this report also shows that this digital technique ismore time demanding compared to hand drawn presentations.The investigation shows that digital visualization technique is a goodcompliment when it is about showing the citizens how future projects willaffect the surrounding.

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.
Relationen mellan utformningen av digitala bibliotek och användarnas behov. En intervjustudie vid Göteborgs universitets digitala bibliotek.
The aim of this thesis is to define digital library, and to investigate a relation between the construction of a digital library and user needs. The main questions to be answered are: 1 What criteria was used when constructing a digital library, particularly concerning issues like purpose, function, design, supply, services, resources and future development of the digital library? 2 How do the digital library system designers and system builders criteria correspond with those of postgraduate researchers? And what factors affect the use? A digital library is an enterprise that gives access to information stored digitally and directly available on the net. The crucial is that the enterprise has a control over collection of information and responsibility to make it available to a defined group of users. In order to investigate the relation between the construction of the digital library and user needs, I have interviewed five key people involved with the work with the digital library and twenty postgraduate researchers from the Gothenburg University.
Interaktioner med nya medier i pedagogisk dokumentation : appen på framväxt?
The overall purpose of this study is to examine how preschool teachers make use of digital tools in correlation with pedagogical documentation. More specifically, the purpose is to interview preschool teachers about their ideas and their use of the digital tool Förskoleappen to record and document childrens learningprocesses. The purpose will be answered with help from the following questions: In what way do preschool teachers use Förskoleappen in pedagogical documentation? What ideas and views do preschool teachers have about digital technology in general and Förskoleappen in particular? In order to find the answers to our questions we carried out a qualitative study in the form of interviews with six preschool teachers from two different preschools. We have used the designtheoretical perspective as our theoretical frame.

Implementering av styrgränssnitt mellan leksaksstridsvagn och digital signalprocessor
Denna rapport omfattar ett 15 poängs (22,5 högskolepoäng) examensarbete vid Karlstads universitet. Arbetet har utförts på plats hos BAE Systems Bofors i Karlskoga. Företaget ville kunna styra en radiostyrd leksaksstridsvagn med en laserpekare. En kamera ansluten till en digital signalprocessor (DSP) skulle kunna detektera var en laserpunkt befinner sig och styra stridsvagnen mot den.Ett styrgränssnitt mellan DSP:n och leksaksstridsvagnen konstruerades och byggdes med hjälp av en programmerbar logisk krets. Leksaksstridsvagnens interna signalsystem analyserades.
