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.

1995 startade medlemmar ur Swedish Oral Medicine Society tillsammans med Institutionen förData och Informationsteknik på Chalmers tekniska högskola projektet MedView. Projektets syfte äratt utveckla modeller, metoder och datorbaserade verktyg för att stödja kliniker i deras dagligaarbete och forskning. 2005 lanserades webbcommunityn SOMWeb och projektet gick in i sin andrafas med fokus på nätbaserad kunskapshantering. Den virtuella mötesplatsen togs emot väl och detbeslutades att satsa vidare på ökad funktionalitet via Internet.Denna rapport beskriver utvecklingen av en webbapplikation som möjliggör åtkomst av denmedicinska bilddatabas som byggts upp under MedView-projektet. Som utgångspunkt förapplikationens funktionalitet och innehåll står skrivbordsapplikationen MedImager.

The main purpose of this thesis is to contribute to the understanding of information needs of eight vocational studies teachers at the Handicraft Programme at a senior high school. I have analyzed the teachers? needs of information and the empirical material has been collected through interviews with eight vocational studies teachers. To analyze the interviews I have used Lars Höglund and Olle Persson?s model for information needs and a model for information sources.

This essay aims to investigate the perceptions of responsible personnel in a primary school about the use and importance of EQ, emotional intelligence, in the school's early years. With a hermeneutic approach and by qualitative interviews, we have taken note of the respondents perceptions about EQ. The result shows that EQ can be understood in different ways. Instead of having a common understanding of what EQ is the respondents mention that there are different areas associated with EQ.  Two major results are 1.

Denna rapport handlar om ett examensarbete utfört åt multimediaföretaget Animero. Det är ett litet företag med åtta anställda som jobbar med olika multimediaproduktioner med fokus på webb- och videoproduktion. Problemet för Animero var att det saknades en ordentlig kravspecifikation i projekten och att kunderna brukade utgå ifrån vad de själva tycker om istället för att tänka på dem som ska besöka webbplatsen. Vårt uppdrag blev att utveckla en applikation som ska ta fram underlag till en kravspecifikation vid beställning av webbplatser. Applikationen ska samla in information om kundernas målgrupp, deras företagsidentitet och de funktioner de vill ha med på webbplatsen.

In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant.

The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.

This report is an examination paper in computer science at University of Växjö. The report will focus on the possibility to create adaptable systems and to cost calculate the work needed to modify a system to meet new demands. A project [demos] developed by Interactive Institute studio [12-21] in Växjö is the starting point in our work. They have during a period of two years developed a prototype of a system which intends to get youth and democratic selected representatives a communication platform where they may communicate with SMS. Today they are in a position when they want to develop the system for other user groups with slighter different purpose and to do that they need a more flexible system.

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

This is a qualitative study which purpose is to examine the experiences of the recovery process after a treatment for eating disorders.                                                         The questions we have decided to examine are; how did the women adapt to a healthier life after treatment, what are the women's perceived experiences of the aspects related to identity and identity work, and what external social influence was seen as important for their adjustment process to a healthier life?Methods: We have used computer-supported and semi-structured interviews. There were a total of nine women who took part in the study.                                                                                                                    Results: Majority of these women have been recovered from their eating disorders, but some still have major or minor problems. They found it rather difficult to adjust their life's without an eating disorder.Conclusions: Increased self-awarness led to greater control over the eating disorder. The women could begin to confer the new features that they identified with.

Computers together with Internet have been growing enormously, during the last decade and the area of information technology has been growing in the same speed. As long as the surrounding environment evolves, the business models must within the IT-area, keep the same pace. So, how do business corporations handle this change to attract customers? How do the dominant business models look like? In many cases, they are apparently much the same. But what differences can we see and what areas can be improved? We have showed that the IT area isn?t just one, it consist of several segments.

The purpose of this master's thesis is to investigate how the students at Chalmers University of Technology at Lindholmen in Gothenburg use libraries in their schoolwork. The empirical material consists of the answers of questionnaires that were handed out to two classes of students, on the second year of their education. To illustrate the topic there are a theoretical frame and examples of earlier studies. The theoretical frame is Limbergs texts that deal with for example information seeking and how important it is in all education. The earlier studies are about student's different ways of using libraries.

Context. Performance and resource usage is often an important factor for database driven services. Depending on the purpose of the application, choosing the wrong type of database may require unnecessary hardware upgrades or replacements. Objectives. This study investigates the differences in performance and resource usage between different SQL- and NoSQL-databases. The study is a comparison that focuses on how the databases perform in different applications.

With the new generation of smartphones the boundaries for what is a mobile phone and whatis a computer becomes more subtle. 2009 the shipment of smartphones with touchscreen morethan double the 2008 figure and the total amount of smartphones is now over 10 % of the totalworldwide shipments of mobile phones. There?s still one problem to solve and that is the lackof web content specifically adapted for smartphones.The purpose of this paper is to identify and analyze from a user and usability perspective howto make a successful migration and design of a user interface for an existing web basedsystem so that it also fit smartphones.The paper starts with a theoretical reference material containing examples of differentapproaches for design and migration of an interface.A case study is performed and prototypes are designed with support from guidelines andrecommendations in the theory part.The conclusion stipulates that in the present situation there are no shortcuts when it comes tomigration of an existing web based system for the mobile web. The recommendation is aspecific interface for each different unit that are going to interact with the system.Research that analyzes differences between all mobile web browsers would be of greatinterest, a research that hopefully leads to guidelines for what level of mobile web standardthey should at least support.
