Digitala servicescapes : En undersökning om samspelet mellan dramaturgi, storytelling, och servicescapes i en digital miljö
Denna undersökning utgår ifrån Mary Jo Bitners servicescape-modell om hur fysiska miljöegenskaper formade efter en berättelse eller tema påverkar serviceverksamheter. För att sedan implementera modellen i en digital miljö. Resultatet av att nyttja teorierna kring servicescapes på exempelvis serviceverksamheter ger besökare möjlighet att fly undan vardagen, medvetet eller omedvetet, genom en kombination av olika sinnen. I undersökningen såg vi att besökarens självmedvetenhet kunde jämföras med Mihaly Csikszentmihalyis teorier om ?flöde?, där medvetandetillståndet hos en individ blir uppslukat av individens aktivitet.
Framkomlighetsanalys med hjälp av en digital terrängmodell och kartdata
Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.
Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie
This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.
Information och interaktion. En studie av högstadieelevers informationssökning och informationsanvändning.
The aim of this master thesis is to examine information seeking andinformation use among high school pupils in two Norwegian highschools. The main research question focuses on different kinds ofinteraction or lack of interaction in the pupils? information seeking andinformation use.The theoretical framework of the thesis is based on a socioculturalperspective which allows for a specific focus of various forms ofinteraction. I investigate interaction in relation to concepts such associal practices, previous experiences and meaning making. Theempirical material consists of data from a large scale questionnaire (n=217) and in-depth interviews with six pupils.The results show that these pupils are used to interact with digital tools.The pupils trust printed sources more than digital ones, but at the sametime they prefer digital sources since these are easier to handle, it isquicker to locate information and this is easier to understand.
Digital kompetens : Om elevers ordbehandlingsfärdigheter i grundskolan
Syftet med denna undersökning var att undersöka den digitala kompetensen hos en grupp elever i årskurs nio på en skola i Stockholmsområdet. Utöver detta undersöktes några utvalda variabler för att avgöra deras eventuella inverkan på den digitala kompetens eleven tillägnat sig. Begreppet digital kompetens utnyttjas bland andra av EU-parlamentet och organisationen OECD vilka publicerat varsin skrift rörande nyckelkompetenser för livslångt lärande. Dessa två ger, tillsammans med en norsk undersökningsgrupps publikation, en gemensam definition av begreppet digital kompetens. Denna undersökning fokuserade dock enbart på ordbehandling, ett område inom den digitala kompetensen.Den empiriska undersökningen genomfördes med hjälp av en provliknande enkät där eleverna fick besvara frågor rörande ordbehandling.
Oberoende skivbolag i förändringstider : Om den förändrade affärslogiken i skivbolagsbranschen
During the last decade the conditions for the music industry have been changed significantly. With the dropping sales of physical phonograms and the increasing illegal file sharing, the record labels have been forced to adapt and thus seek alternative sources of income next to the traditional sales of phonograms. Our purpose was to investigate how smaller Swedish record labels adapt themselves to the changing environment within the music industry and which new alternative sources of income they can use to finance their music production. To do this we used a deductive approach where we started by researching theories we thought were relevant to the subject, which we then used to get valuable information out of our informants.From our empirical investigations it appears that the independent record labels are rather positive about the future and that they will be able to survive, even though they will have to change their ways of working to a large extent. Our results show that the record labels as we know then will disappear.
Representativa testnät försvenska eldistributionsnät
This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.
Förbränning av pellets framställda av defibrerad granråvara :
Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged.
The milling process creates a wide range of particle sizes.
Effektivisering av urvalsprocesser vid analysering av björnspillning : Ett förslag till den svenska förvaltningen av brunbjörn Ursus arctos
The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.
DIGITALA RUM OCH RUMSLIGA DIGITALISERINGAR - hur hemmet tar plats p? Instagram
In a world obsessed with the visual our homes have gone viral. Through the frame of Instagram family members seems switched to furnitures and the so-called smartphone surely opened the door to new, digital places. Social media has become part of the life of many and, as an effect, also of the way we do our homes. In the era of digitalization, the concept of sharing has gotten some new dimensions where the borders of private and public, here and there, becomes blurred. Why do people post pictures of their homes on Instagram? How is it performed and what boundaries are pushed in the process? These have been some of the main topics guiding this thesis.
Utveckling och tillämpning av modeller förkvantifiering av de ekonomiska konsekvensernaav ökad förbrukningsflexibilitet inom eldistribution
One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.
Det moderna biblioteket inätverkssamhället : En studie över kulturpolitikers och bibliotekariers åsikter om bibliotekens användande av sociala medier
?The modern library in the network society?A study of cultural politicians and librarians opinions about libraries' use of social mediaSocial media is becoming more and more interacted in our daily lives and Carlsson (2013) argues that today's libraries have undergone major challenges in the digital information technology's entry in the library arena. The new technology has led to sum up in one question: how a library should relate to the digital information technology, the issue has applied in particular the social communications media, such as Facebook, Twitter and more. The purpose of this paper is to examine the culture of politicians and librarians 'perceptions of public libraries' use of social media linked to the libraries and their democracy promotion efforts. This is analyzed from Castells theories about the network society and the digital divide.In summary, the study concluded that the majority of the culture politicians and librarians believe that social media is a part of the future of the library.
Tillgång eller ägande : En studie i konsumentvärde på marknaden för digital underhållningsmedia
Syftet med uppsatsen har varit att genom kvalitativa intervjuer lyfta fram motpolerna kringdagens konsumtion av digital underhållningsmedia och fastställa om konsumenters syn på värdekan relateras till deras val av att antingen betala för ägandet eller för tillgänglighet av den. Metoden har bestått av åtta stycken kvalitativa intervjuer där respondenter fått frågor om sinkonsumtion av digitala underhållningsmedia inom; musik, video, spel och podcasts. Uppsatsen kommer fram till att konsumenter ser värdet i användningen av mediet och inte iägandet av det. Konsumenterna vill således hellre strömma sin media än att ladda ner den. Deväljer därför mer eller mindre obehindrat den tjänst som har bäst utbud.
Data Propagation and Self-Configuring Directory Services in a Distributed Environment
The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.
Integrering av Digitala Färdskrivare och Telematik för den nya Europeiska Standarden
This Master of Science thesis project handles issues around managing data from the digital tachographsystem. European legislation states that companies must download the data of the digital tachograph systemand store it for at least one year for control purposes. The system stores data on the vehicle unit located inthe driving compartment and on smart cards personal for each driver.Acquiring data from the previous analogue tachograph was done instantaneously since the data wasphysically printed to a circular paper chart when driving. To acquire data from the digital system one mustperform a download from the vehicle unit and later transfer it to some form of backup solution for longterm storage. Data must also be downloaded from the driver smart cards.Download of data from the vehicle unit is the most time consuming task and may take up to 30minutes pervehicle.
