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.
Att organisera beståndet eller ?Äntligen hittar man!? : om hylluppställning och exponering på Arkenbiblioteket
The aim of this master?s thesis is to examine how libraries can organize their collections in terms of library shelving and displays and to what extent these activities stem from a desire to create a user-friendly library. The thesis is based upon a case study of Arkenbiblioteket in Sweden and the material consists of a literature study and qualitative, semi-structured interviews with three librarians at Arkenbiblioteket. The theoretical framework consists of theories on information-seeking behavior, classification and displays. These theories form the basis of the analysis of the empirical material.The main reason for the changes in shelf arrangement at Arkenbiblioteket was a desire among the library staff to create a user-friendly library.
Klassifikationssystem för en medicinhistorisk samling en jämförande studie av SAB och NLM
This thesis deals with classification of the subject field history of medicine. The two classification systems SAB and NLM are compared in order to find out which one is the most adequate to organize a small collection of history of medicine. SAB and NLM are the two most commonly used classification systems in medical libraries in Sweden today. NLM classification system specializes in medicine and SAB is a universal classification system. Our purpose with this study is to find out the pros and cons of each system, whether the systems treat the subject history of medicine in a satisfactory way and what kind of classification system that is better for this assignment, a specific one or a general one.
Olika modellering av vårdprocesser utifrån metaforiska perspektiv : ? Skapar det nya drivkrafter för processutveckling?
The study was conducted in Jönköping County Chamber of fibrillation and is about change and improvement of process modeling technology. The process for treating patients with fibrillation is in the need to evolve and improve. In order to develop the care they needed a current state description which usually is made with the traditional process modeling tool.Many scientists and health professionals is in the opinion that this technology gives a too rigid image to describe the care processes. It also does not sufficiently take into account the human aspects. This reasoning suggests that the process modeling technology in healthcare is in the need to develop multiple perspectives.
Fra?n beso?kare till boende : En studie om ma?tning av destinationsimage ur inva?nares perspektiv
It has become increasingly common for cities and municipalities to take greater account of the place marketing, and to see the physical location as a brand. An early step in this process is to make the image measurements of the place, in order to develop better marketing strategies. A method often used in tourism research for this type of measurements is Etchner and Ritchie's theoretical framework. The framework is initially designed to measure visitor's image of a tourist destination.Almost all previous research in this area is based on the visitor's perspective, but Olofsson and Skredsvik have used this framework to measure a location's image among the residents. They feel that the residents of a place can be seen as ambassadors of the place because they know the site well.
Triac Driver Platform
In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..
Ett kommunikationssystem för fiberoptisk överföring av bilddata förvärvad av en miniatyriserad undervattensfarkost
This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.
IÖV- Kollektiv bestraffning ur ett familjeperspektiv : En kvalitativ studie som berör Frivårdens arbete med de anhöriga, ur de frivårdsanställdas vinkel
This is a qualitative study based on eight interviews, four of which have been probation inspectors and three have been external controllers, or controllers as they say, and one have been an email interview with the headquarters of the correctional treatment. The interviews have been made on probation service offices in southern Sweden.The purpose of this study is to investigate how the professionals in Probation service see their work with intensive supervision with electronic monitoring. We are interested in their work from mainly three aspects, how they look at their control, how they see the intensive supervision with electronic monitoring as collective punishment and how they work with the client's family.In our results it emerges through interviews that probation staff in general find it difficult to work with the Children Convention (CRC) and the law when it comes to intensive supervision with electronic monitoring. They mostly do not believe that intensive supervision with electronic monitoring is a collective punishment for the adults but when it comes to children it becomes a longer discussion with different arguments and thoughts.Our results have found that in comparison to prison, most people seem to find that intensive supervision with electronic monitoring is a decent punishment. Most of the professionals are aware, and think it's important to recognize, that they are in a position of power in relation to the client.In the analysis, we establish an outcome from the interviews into our theories and trying to find a connection between them..
Flickor och elektroniska spel: Fokusgruppintervjuer med flickor om deras syn på och användning av elektroniska spel
The aim of this Masters thesis is to examine what part and importance electronic games play in the life of girls, how the girls use electronic games and what the girls think and say about their use of electronic games. We also intend to examine what girls have to say about electronic games at the public library. Our attempt is to illuminate and bring knowledge to those who work within the library with the selection, purchase and conveyance of electronic games. Method used in the survey is focusgroup-interviews with girls in the age between 12-14 years in three different schools. The findings are related to four different perspectives, theory of child development, from a gender perspective, theories of understanding how young people use computer games and theories to understand the purpose of public libraries.
System för att upptäcka Phishing : Klassificering av mejl
Denna rapport tar en titt på phishing-problemet, något som många har råkat ut för med bland annat de falska Nordea eller eBay mejl som på senaste tiden har dykt upp i våra inkorgar, och ett eventuellt sätt att minska phishingens effekt. Fokus i rapporten ligger på klassificering av mejl och den huvudsakliga frågeställningen är: ?Är det, med hög träffsäkerhet, möjligt att med hjälp av ett klassificeringsverktyg sortera ut mejl som har med phishing att göra från övrig skräppost.? Det visade sig svårare än väntat att hitta phishing mejl att använda i klassificeringen. I de klassificeringar som genomfördes visade det sig att både metoden Naive Bayes och med Support Vector Machine kan hitta upp till 100 % av phishing mejlen. Rapporten pressenterar arbetsgången, teori om phishing och resultaten efter genomförda klassificeringstest..
Kvalitetsredovisning och undervisning i matematik
The aim with this master thesis is to analyze a scientific material concerning the context between learning and child/student development, and factors which controls process of learning, to create an image with quality account and teaching in mathematics, which then can raise the mathematical knowledge among students.The phenomena which stand in focus for the investigation is: why there is a negative tendency for development of knowledge in mathematics, among the Swedish students that TIMSSs investigations showed in intercultural comparison within the years 1993, 1999, 2003 and 2007.The method is the ethnographical method, which is based on: analyzing scientific theories about learning child/student development, factors which controls process of learning, and factors which controls process of learning the most and qualitative empiric investigation with qualitatively analyzes the questionnaires, which is about factors which are controlling the process of learning and factors which are controlling the process of learning the most.Result of the theoretical and empiric analyzes shows that factors as school environment, attitude for subjects and teaching, controls and influence the learning. To end a unenthusiastic tendency as a negative development of mathematical knowledge among students that is shown in TIMSS investigation and to elevate the students' performance in mathematics, an elevated qualitative account and teaching in mathematics, by the factors named. Safe school environments as the intercultural meeting place, the teachers influence part to the students' subjects' attitude in mathematics and goal related grading criteria in teaching, is all required for e qualitative teaching in mathematics..

The components discussed are trust, commitment, cooperation and satisfaction.
Vad säger bilden?: En utvärdering av återvinningseffektiviteten i ImBrowse
The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.
Måltiden som lärandesituation i förskolan : en kvalitativ studie om pedagogers syn på barns övergripande och hälsofrämjande lärande i förskolan genom den pedagogiska måltiden
The purpose of my study has been to find out how four preschool teachers at four different preschools looks at the pedagogical meal from a health and overall learning perspective. I also want to examine how, through the pedagogical meal the preschool teacher works to promote children´s learning and give them an understanding of need to safeguard their health. To achieve my aim I set the following questions;What are the different types of learning preschool teachers believe that children can acquire the basis of the pedagogic meal?How do preschool teachers describe their work from the pedagogical meal to benefit children´s overall learning?How do preschool teachers describe their work at the pedagogical meal for the children to gain an understanding of their health?The study is based on a qualitative method with interviews and observations, triangulation. The theoretical approach to this study is based on the socio-cultural perspective to learning and development.
