Internet i Kina : digital konvergens mot den femte moderniseringen
Denna uppsats beskriver Internet i Kina i allmänhet, från dess politiska bakgrundsmotiv och inledande grunder till dess nuvarande tillstånd av dynamisk ekonomisk infrastruktur och medel för folkligt politiskt inflytande. Tonvikten läggs vid för Kina unika aspekter, såsom partiinflytande över informationsutbytet, folkliga attityder till fildelning i ett samhälle som bara nyligen erkänt privat ägande samt effekter av kulturkrockar på nätet mellan västlig och kinesisk civilisation. Det argumenteras för att Kina i en framtid kommer att ha ett stort inflytande över cybermarknader och i beslutsfattande om Internets framtida utveckling, genom tekniska, ekonomiska och politiska medel. Slutligen resoneras att Internet i Kina har förändrat och kommer att förändra folkets mentalitet, så att det anammar västerländska tankemönster i liknande utsträckning som i angränsande länder, vilket banar väg för politisk pluralism..
Solenergisystem i Hammarby Sjöstad
Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.
Papper och penna eller tangentbord och skärm? Vilka verktyg erbjuder gymnasielärare i svenskundervisning?
Syftet är att undersöka hur ett antal gymnasielärare som undervisar i svenska ser på datortillgång och datoranvändning, samt vilka krav de ställer på elevernas datoranvändning i kursen Svenska A. Undersökningen genomfördes via en webbenkät, vilken distribuerades under mars 2009. Resultatet av webbenkäten ställs mot beskrivningar av förutsättningar för skrivande och aktuella styrdokument. Tillgången på lärardatorer är otillräcklig och tillgången på elevdatorer är ännu mera otillräcklig. Datormedierad kommunikation används för att effektivisera undervisningen och för att nå eleverna med information.
Analys ac konstruktionsprocessen inom FTC
This thesis work was made to optimize the writing of the construction specificationsat FKA. These construction specifications are created before each plant modificationsthat is started because requirements from the Swedish radiation safety authority(SSM) and internally on Forsmarks nuclear group as constructions / implementationdocumentationThe study was done through seven interviews of two people at three different groupsinvolved in the construction specification and an interview from the group accreditedverification. The four selected groups were selected through an extensive analyticalwork resulted in an elimination matrix where these four groups was considered to bemost involved with the construction specification.The questions asked to these individuals were based on the instructions and sampletext that are described in the construction specification. To ensure the quality of thethesis were to limit itself to the chapters that were considered most relevant toimprove. The analysis revealed a number of points that should be improved, partlyinto the routines when writing the construction specification and when ether sampletext or suggestions should be changed and complemented.
RFID på Kvarntuna stadsbibliotek : Teknikskifte som möjlighet till förändrat arbetssätt?
This two years master's thesis in Library and Information science, examines how the implementation of new technical equipment can affect how staff in public libraries organize their work and activities in the library. One Swedish public library in specific is the subject of research in this thesis, which has been anonymized as Kvarntuna city library. The study takes place in the beginning of the implementation of RFID-technology in the library. RFID, which stands for Radio Frequency Identification, is supposed to make the handling with different types of media in the library more efficient and in connection with the implementation one wants to reorganize work and activities in the library to make it even more efficient and also create a modern library.The thesis' method is qualitative interviews with six members of the staff. The theoretical framework of the thesis is a sociocultural perspective, especially inspiered by Roger Säljö, a Swedish professor in pedagogical psychology.

Borrelia burgdorferi : metodutveckling och tillämpning avseende odling och resistensstudier mot komplement, särskilt interaktion med faktor H
The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.
Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
Förändrad interaktion, förändrat värde? : En kvalitativ studie om värdeskapande vid mänsklig och teknisk interaktion
The progress in the field of technology is often described as massive and its development has had a great impact on the social development (Vetenskapsrådet, 2012). As a result of the digital evolution, there has been a change in the way customer and company interact (Normann, 2011). The traditional way for players to interact with each other required an interaction human to human (ibid), a mode of interaction that now can be replaced or supplemented by todays technology and often Internet-based solutions (Salomonson et al., 2013). These technological solutions, the technical interaction, are often referred to as self-service systems. These systems enables the customer to carry out the tasks previously performed by the company (Hilton and Hughes, 2013).
Kulturen och kapitalet Hur, vad och varför ett antal män läser
This thesis deals with the leisure-time reading of fourteen men with two different occupations, teachers of technology and directors of companies. The main reasons for writing the thesis are that very little is written about mens reading habits and also statistics that tell that mens reading decline regardless of educational level. The purpose has been to compare the reading and relations to literature between the two groups of men and to find out if any differences have to do with factors such as social background or age. The questions we have asked our collected data has been what, how and why the men read. We have tried not to investigate the work-related reading although we are aware of the difficulty in separating this from the leisure-time reading.
Ledarskapsprogram för innovation
Since the 28thof May the project to develop an internal Innovation Leadership Program (ILP)on Accenture has been running and came to an end in November the same year. The taskwas formed into a master thesis and given to two students at the Royal Institute ofTechnology in Sweden.Since the start the content and structure of the ILP has been established based on the resultsof a theoretical study, a gap analysis and an external and internal benchmarking. The theoreticalstudy focused on articles, books and lectures about innovation, creativity and pedagogy. Subjectssuch as leadership, motivation, reflection and coaching were studied as well, but in a smaller scale.The gap analysis consisted of eleven interviews with people from different career levels withinAccenture and the goal was to establish the view of innovation and creativity among the employees.The interviews also asked about the knowledge the participants had about Technology Lab in orderto get insight of how to improve their communication and cooperation with people in client projects.Internally a similar program was studied called Minority Leadership program, whom will not bedescribed further in this report, to get inspiration. The external benchmarking was conducted onStanford and was very successful.
Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Rum för musik på biblioteket: En fallstudie av Bibliotek 10 i Helsingfors
The aim of this master's thesis is to study how the design of the music library space affects how it is used and its role as an arena for culture. This is done in form of a case study of Library 10 in Helsinki, a public library branch that specializes in music and information technology. The backdrop to the study is the changing context for cultural activity in the information society and the role of public libraries as public space and meeting place. By analyzing the distribution of space in the library, the distribution of functions and artefacts and the spatial use of the room, I interpret the ways in which this distributional logic produces a unique place for music and culture. I discuss the music library design in a space and place perspective, utilizing theoretical tools from cultural geography and the space theories of Henri Lefebvre.
