Förändra, förbättra, förnya? Retuschering av medeltida kalkmåleri
The aim of this paper is to take a critical look at retouching of medieval mural paintings inSweden. This is done by firstly examining the different methods of retouching, including thematerials used. Secondary it tries to answer the question of which intentions have guided theconservator?s decisions dealing with the retouching. The medieval mural paintings in Swedishchurches have three major functions today.
Talar samlingarna? Hur bibliotekarier lär sig sina samlingar vid nationalbiblioteken
National libraries hold large, valuable repositories of often unique materials. How can we ensure that the knowledge is accessible without endangering the materials that hold the knowledge? Digital preservation is meant to solve this problem. With more and more material being accessible digitally, users are expected to do more and more of the finding on their own, instead of being guided by librarians. What kind of knowledge do the librarians have, that cannot be mediated through a system? How is the knowledge of experienced librarians passed on to new librarians? What is the difference between physical and digital materials? I have interviewed senior and junior librarians of Det Kongelige Bibliotek in Copenhagen, Nasjonalbiblioteket in Oslo, the National Library in Helsinki, and Kungliga Biblioteket in Stockholm to learn about their journey to knowledge of their collections.
Kravbalansering i produktutvecklingsprocesser: Kritisk granskning av en beslutsmodell för produktutveckling
The object for this study is a company developing and manufacturing vehicles for heavy transportation. The company distributes their products on a global market. Therefore the company is required to have efficient internal production development processes in order to successfully beat the competition. The purpose of this master thesis is to study how this particular company intends to implement their standardized theoretical product development process within their organization and how well it is done. We intend to identify and specify if the process has any unexploited capacity.
Skattning av fordonsmassa med driftstatistik
In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.
Solenergi i Norrra Djurgårdsstaden
This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.
Absolut avkastning på den nordiska hedgefondmarknaden : - En realitet eller önsketänkande?
Hedge funds? importance within the financial system has during the most recent years increased dramatically. These special funds are unique instruments that differ from traditional mutual funds in a variety of ways, however especially in how they expect returns. Due to the fact that hedge funds are able to hold short positions they possess the possibility to become market neutral investment vehicles.Because of this possibility to sustain positions neutral to market fluctuations, the concept of absolute returns became a unique selling point for hedge fund managers and promises of stable returns unchallenged by market conditions was assured. This research paper aims to examine the theory of absolute returns in hedge funds by examining hedge funds from the Nordic region during the last years of economic turmoil that has occurred by analyzing the results from their strategies, partially by quantitative measurements as well as qualitative. The results show that none of hedge fund strategies managed to deliver absolute returns over the chosen period..
Kameraövervakning och deliberativ demokrati - En normativ studie av dagens kameraövervakning utifrån teorier om panopticon, den andre och det kommunikativa handlandet
The main aim of this thesis is to introduce a normative perspective to surveillance studies. I examine how the use of videocameras or CCTV-systems can create a social sorting and, then, try to answer why it ought to be reconstructed based on a normative study.For the empirical analysis I use Foucaults theory about the panopticon, maintained by the psychological subjection of the common citizen in the modern world, together with Lianos theory of a more socio-cultural surveillance in the post-modern world. The empirical examination is, furthermore, guided by a theory that describes the construction of the stranger, which today, is not explicitly excluded, because everyone is a stranger in some way, but rather depicted as the other due to institutionalization.The post-modern society today can no longer be built upon a common or divine moral or norm. Thus, I have chosen a normative method, using a deliberative democracy derived from Habermas, focusing on the communicative practice, that can engage and include every citizen in a democratic process. This is necessary for both deciding whether videocameras should be installed and whom and why some should be under surveillance ? to avoid a social sorting that both can constitute and undermine social trust and increase the gap between the governing and the governed..
Bränsleceller som applikation i bilar : Enstudie av Fuel Cell Electric Vehicles och deras potential för framtida kommersialisering
Användningen av personbilar har ökat stadigt i Sverige och världen i stort de senasteåren, vilket lett till ökade utsläpp av koldioxid. Samtidigt har oljepriset nåttrekordnivåer, och många menar att utvinningen av olja redan har nått sin topp. EU hardessutom satt som mål att medeltemperaturen på jorden inte får stiga med mer än maxtvå grader Celsius, och att till år 2050 reducera koldioxidutsläppen med 80 %. Detta ärenbart möjligt om nya, gröna drivmedel och drivlinor fortsätter utvecklas ochframförallt kommersialiseras. Användningen av förnyelsebara energikällor har ökatkraftigt, vilket skapat förutsättningar för bilar drivna av el.
Kvalitets och förbättringsarbete för ITtjänsteföretag
Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.
Rengöringsmaskin av produktionslina : Rengöring av band i produktion
The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.
Framtidens elbilar utmanar nutidens elnät : Påverkan av ett ökat antal elbilar på ett halländskt elnät
The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.
Mörkerkörning: Realtidssimulering och visualisering av fordonsbelysning för mörkerkörning i körsimulator
To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.
Det sociala samspelet : Vad händer i det sociala samspelet i barns leksituationer på förskolan
In my degree project I have chosen to write about the social interactions in children?s play. Iwanted to study their free play and the time when their teachers tell them what to play to seewhat their social interactions look like. The purpose with my research is to study whathappens in the social interactions in their different playing situations.I performed three observations of the free play and three observations of the guided play at apreschool to study what social interactions that takes place in the different playing situations.What happens and what patterns can I find in their play.In my research I had some questions that this project rests upon:What happens in the social interactions in the different playing situations?How do the children?s different social interactions look?The children that I have observed showed me that when they are interacting they especiallyuse their cognitive abilities, because an interaction needs a certain mental development.
Preparering av kabelände inför statorlindning
At Uppsala university scientists have during the last years developed and built wave energy converters. This project is called "Lysekilsprojektet". The development has come so far that they are currently investigating how to gain profit in a mass production. For that reason they want to automate as many steps in the production as possible.The winding of the stator is one part that is being automated using industry robots. The stator is cable wound unlike many other generators.
Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm
When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.
