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.

This paper deals with testing the method Reflectance Transformation Imaging (RTI) on the copy of the Piraeus-lion in Historic Museum in Stockholm. The purpose is to find out if it is possible to gather more information about the runic inscriptions. RTI is a method that records the surface normal of individual pixels in a digital photograph by analyzing the impact of light coming from different angles of entrance. RTI produces sort of a 3D-image of the object. There will be an overview of earlier interpretations of the runic scripts written on the lion as well as an overview of Varangians in the southeast.

The purpose of this study was to gather knowledge about the functioning of the rein tension meter and test it for future studies of match and mismatch between rider and horse. We looked specifically into the possibilities to use a rein-tension meter to determine the quality of cooperation between horse and rider. We examined whether a rider shows a specific tension pattern and also if certain patterns could be recognised for a specific horse. During the study, a manual with pictures and text was written to support the practical use of the meter. The manual describes in a simple way the first steps in the installation and use of the meter.

The purpose of this essay was to determine whether signs as alternative and augmentative communication is one possible resource for children?s language development. Based on my research questions How educators perceive the importance of SAAC as possible resources to enhance children's communication?, For which children is SAAC used? and How does educators perceive child?s best in communicative interactions? have I interviewed six educators in two different kinds of municipalities with different kind of positions.In my background I lift the importance of communication for the human being, what happens to the children who doesn?t get stimulated to their language and child?s best. My literature has shown that children need to have an incentive to acquire a language and that SAAC is mainly created for children with special needs.

Augmented reality is an interesting technology which has increased in popularity the last couple of years. Even though we see more and more of this technology the use of it doesn?t match up to its true potential. This paper aims to investigate the possibilities of this technology and illustrate how companies can use it in their business to reach out to customers in a new and exciting way. The study consists of three parts.

Dagens teknik erbjuder en mängd olika sätt för människor att kommunicera och interagera med varandra. Denna uppsats är en studie i bilddelning på sociala medier med fokus på amatörfotografers användande av tekniken i syfte för att nå ut med sina fotografier. Huvudfokus lades på vad för strategier de använde sig av, men även på användarnas olika målsättningar. Med hjälp av tidigare forskningsarbeten och djupgående intervjuer har vi lyckats återkoppla den egna empirin med våra teoretiska utgångspunkter och dragit slutsatsen att användandet av sociala medier i syftet för att nå ut med sina bilder till andra människor varierar väldigt stort från person till person. Hur tekniken används för detta syfte är därmed unikt för den individuelle användaren, dock har vi lyckats identifiera vissa likheter i användandet av sociala medier i dessa syften. .

In time with HolmenSkog district Egenskog Norrköping´s decreasing mountain of cleaning, the office started to look around for new alternative cleaning strategies to lower the costs connected with cleaning. One option was to make the inventory strategy more effective and after a phonecall with the head of the district, Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected depended on age and different mixtures between pine (Pinus sylvestris), spruce (Picea abies) and birch (Betula pubescense and Betula pendula).

This essay is about how the library can make a difference inintegrating the minority Roma people into the Swedish society.Roma people have been subjected to persecution anddiscrimination for a long time. In this essay, I examine theactivities, functions and capabilities of libraries that can have apositive effect for the integration of the Roma people. Myquestions are: How can libraries reach out to the Roma people andwhat function do the library have for the integration of the Romapeople? I have used Marianne Anderssons and Dorte Skot-Hansens theory the four functions of the library ? the culutralcenter, the knowledge center, the information center and the socialcenter. Based on this theory, I have interpreted and analyzed thematerial that I have gathered through interviews and literaturestudies such as thesis, dissertations, repors and parliamentdocuments.

Lars Höglund AB is one of Scandinavia?s most qualified manufacturers of sheet metal products and provides custom designed products of very detailed precision. One of the main methods of manufacturing is laser cutting. When Lars Höglund AB signed up a new customer, with high demands in tolerances for the products, Lars Höglund AB thought it would be necessary to know the capability of the laser cutting machine. Also the process of how to retrieve this capability was interesting. The capability will be researched for the following elements: Cutting right angles in squares with a corner radius of 1 mmCutting corners which are not right angleCutting of circles with constant radius Measurements were made on 150 pieces of sheet metal details, which had been cut out by the machine.  The data from the measurements where later used to study the capability.

Today, we see tendencies of politicians being more active in social media using selfies. According to previous research using selfies is associated with being self-centered and narcissistic. It is not known though what implications the behavior will have for a selfie-using politician in terms of chances of being elected. This study aims to contribute to the research on political communication and social media behavior. More specifically the study intends to investigate whether there is a difference between voters' views if a politician uses selfies or not, and whether there is a difference by gender.

Magnetgärdets transformatorstation är belägen i Ludvika och ägs av Västerbergslagens Energi AB. Transformatorstationen är nyligen ombyggd och nu mer placerad inomhus, vilket gör att påkänningar från väder och vind minskar. För att minimera behovet av personlig tillsyn och öka tillgängligheten behövs dock någon form av tillståndsövervakning.Syftet med examensarbetet har varit att undersöka om det med hjälp av värmekameror är möjligt att tillståndsövervaka de kritiska punkterna i transformatorstationen. För att fastställa detta har teori kring tillståndsövervakning, termografering och värmekameror sammanställts tillsammans med utförda mätningar och tester. Resultaten har sedan diskuterats för att se om ett möjligt lösningsförslag kan presenteras.

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

This thesis examines how library employees experience the library as a meeting place. Our questions are: What effect has the concept of a "library as a meeting-place" for library staff?How do they see the library as a meeting place? How do they see their workplace as a venue for meetings? The respondents interviewed work in public libraries. We were inspired by a cultural geographic theory that we re-designed. The following divisions were made in order to give the work a definitive structure:The "mental space"The library as a meeting place on a global and universal level;The "conceived space"Librarians and planners' thinking on the specific library as a meeting place;The "living space"How library staff perceive that the library is used as a meeting place in reality.In our analysis, we use a phenomenographic qualitative interpretive methodology.

The primary aim of this thesis is to examine female lawyers' relationships to information from different angles. The starting-point is that the legal information, retrieved from through different information sources, is not free from values and subjectivity. The commonly presumed objectivity of legal information is questioned, based on the fact that this kind of information has developed and changed historically in the context of, and in relation to, society. Another aim is to find out how the female lawyers experience their situation in a traditionally masculine working environment. Qualitative interviews have been carried out with seven female lawyers involving questions about their daily work about the sources that they are using.
