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.

Balansering av en storskalig vindkraftsutbyggnad i Sverige med hjälp av den svenska vattenkraften

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Konstf?rst?relse/F?rst?relsekonster: En unders?kning av konstruktiv ikonoklasm som konstn?rlig process

Building on the concept of constructive iconoclasm as a creational force of iconicity, this thesis examines how the contemporary iconoclastic discourse is related to artistic process. Studies have shown that the performative act of destroying art that is an historical phenomenon is highly present within the contemporary art discourse today. Due to the many dimensions of contemporary art, the ways in which iconoclastic deeds appear may differ from the historical narrative. While iconoclasm and iconicity are being reciprocal processes that can only exist in relation to each other and their context, there are signs that the destructive act itself is being recontextualized by contemporary artists. Guided by the framework of Norman Fairclough?s critical discourse analysis, the thesis examines the processes of conceptual and constructive art destruction by analyzing the discourses of two case studies situated in the contemporary art market.

?Något fel är det med honom, han kommer säkerligen aldrig att bliva en god medborgare? : En studie om barnavårdsnämnden, skolan och de avvikande barnen i 1930-talets Malmö stad

This study, a document analysis with a qualitative approach, explores children, under 18years, who have been subject to measures of child welfare in the city of Malmö during theyears 1935-1937. It also explores the school's role in this context. The questions that the studyis guided by is: How was children described in the Child Welfare documents in Malmö duringthe years 1935-1937? And what role did the school have in Child Welfare work and whatmotivated this? The theoretical approaches are Foucaults theories of power, control anddisciplining.It appears from the study that the school and child welfare authorities had a close cooperationwith the purpose to control the upbringing and disciplining of the children. It was through theupbringing that the deviant child would become a "normal", docile and good, industriouscitizen.

Lugnet före stormen : En studie om hur Räddningstjänsten Medelpad arbetar med kommunikation och planering innan en kris

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

Automatisk viktkontroll av glascontainer

This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.

Att bli förälder till ett prematurt barn - Litteraturstudie/Becoming a parent when a child is born premature - Literature review

Background: Almost every 20th child is borne premature in Sweden, before the parents are ready to care for a new family member. The parents need to cope with the stress and anxiety of having their newborn child in the neonatal ward and influenced by nursing care of neonatal staff grow their parental role.Purpose: The aim of this study was to illustrate experiences of parenthood within the care of premature at the neonatal ward.Method: A review where 18 articles between 2000 and 2005 were chosen and examined. The articles were analysed according to VIPS, which facilitates the practical use of the result.Result: The study reveals that parenthood is experienced as a time dependent process with three phases, primary, secondary and tertiary, where the parent?s needs and experiences changed character. The parents experienced that they developed from passive to active in the care of the premature child when the neonatal staff guided their participation, gave information/education and support.

Närståendes delaktighet inom psykiatrisk slutenvård : Ur ett livsvärldsperspektiv

Today adult patients' relatives are seen as a resource in psychiatric care but few researchers have examined the lived experience of relatives' participation in psychiatric care. The aim of this study was to illuminate how mental health staff and relatives of adult patients experienced the relatives' participation in psychiatric care on hospital ward.The study was guided by a phenomenological approach and a lifeworld perspective. Data were collected through in-deep interviews with ten adult patients' relatives and three group-interviews with ten mental health carers from two hospitals in Sweden.The essence of the lived experience of relatives' participation in psychiatric care in hospital ward is described in the constituents: invitation to participate in psychiatric care; meet the staffs' care; to participate in own or others terms; bring the common everyday world with you; feel burden; participation a trip in time and space. The findings of the study show that the relation between the staff and the relatives are important for the relatives' participation in psychiatric care. The relatives' participation can alter from no participation to a meaningsful participation, from suffering to well-being.This study can help medical staff to understand relatives and their participation in a new way..

Skilda världar? Publiceringsmönster och synen på publicering vid två vetenskapliga institutioner

This Master?s thesis aims to map and analyse publishing patterns at two academic departments at the University of Gothenburg - the department of Physics and the department of History. The investigation has been guided by a set of questions: Who chooses to publish their scientific outcomes? In which forums do they publish findings? In what kind of media are the results published? What type of findings get to be published? The departments' publication lists have been examined, covering the years 2004-2007. Furthermore, ten scientists have been asked to describe factors contributing to their individual publishing pattern.

Karaktärisering av hästerns gångarter med accelerometerteknik

In today?s horse keeping, there is an increasing awareness of the importance of movement and activity for the horses comfort and tenability, while tradition has it that horses should be kept in boxes and small paddocks. In order to develop housing systems that fulfils and optimizes the horses needs regarding movement and activity, we need to know more about factors that influence the activity patterns of horses. A first step is to be able to record and analyze the gaits in horses with an automated system. This could be done by use of accelerometer data.In this pilot study, existing accelerometer technique was used to characterize the different gaits in horses (walk, trot and canter) by studying how their respective signal patterns differ and how this is influenced by the size of the horse.The accelerometers being used in this study measures the movement in three different spaces; horizontal, lateral and vertical.

Hydroakustisk kommunikation med bandspridningsteknik

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

VOX : sittmöbel för det offentliga rummet

A trend in modern landscape architecture is to design pedestrian streets so that vehicles and people move in the same area. By doing this, traffic tends to slow down. On the market though, there is a lack of furniture that corresponds to the requirements of these kinds of public places. Therefore, I have designed this furniture, called VOX, which is planned to be used on streets, schoolyards and squares. One objective has been to promote the product to the industry.To achieve this, I have been in contact with people from different professions, which have all influenced my designprocess.

Omkonstruktion av slädsystem

Examensarbetet som beskrivs i denna rapport är ett avslutande moment för en magisterexameni Teknisk Produkt- och Produktionsframtagning på Högskolan i Halmstad.Nilsson Special Vehicles i Laholm gav i uppdrag att förbättra slädsystemet i derasbegravningsbil baserad på Mercedes E-klass. Nuvarande system är föråldrat och harendast genomgått små förändringar sedan det utvecklades. Materialet, som är olikastålprodukter, gör att vikten är hög. Utformningen av systemet är från början utformat förett annat chassi än Mercedes vilket gör att det passar dåligt i denna bilmodell. Det ärframförallt lasthöjden som påverkas negativt.
