  1. 1. Mobile Network Operators and Cooperation : A Tele-Economic Study of Infrastructure sharing and Mobile Payment Services

    Författare :Jan Markendahl; Jens Zander; Per Andersson; Heikki Hämmäinen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication theory; Telekommunikationsteori;

    Sammanfattning : Mobile network operators are currently faced with a number of challenges at the market. The revenues from voice services have decreased the last couple of years. Mobile broadband access services are being adopted and the demand is increasing. The increasing traffic volumes require investments in order to increase the network capacity. LÄS MER

  3. 2. Cooperation for Secrecy in Wireless Networks

    Författare :Frederic Gabry; Mikael Skoglund; Eduard A. Jorswieck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The growth of wireless networks has been considerable over the last decades. Due to the broadcast nature of these networks, security issues have taken a critical role in today’s communications. LÄS MER

  4. 3. Mechatronics engineering : New requirements on cross-functional integration

    Författare :Niklas Adamsson; Margareta Norell Bergendahl; Eva Lovén; KTH; []
    Nyckelord :Mechatronics engineering; product development; multidisciplinary teamwork; organizational integration; cooperation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Several industrial sectors experience an increased reliance on mechatronic systems as electronics and software are being embedded into the traditional mechanical systems of these industries. Important challenges within mechatronics engineering comes from management of multi-disciplinary development project teams and the highly complex scope of problems, which in turn require extensive coordination and integration, both in terms of technical and organisational matters.

  5. 4. Social Awareness Support for Cooperation : Design Experience and Theoretical Models

    Författare :Ovidiu Sandor; Yngve Sundblad; Cristian Bogdan; Steven Benford; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HCI; CSCW; social awareness; user-centred design; Spatial Model; Aether Model; communities; knowledge; Computer science; Datavetenskap;

    Sammanfattning : This thesis addresses the research question of how social awareness support in computer systems for groups and communities can be designed in a successful way. While the field of human-computer interaction has been working with similar questions for more than 20 years, many aspects of people’s cooperation and the way those should be considered in system design still need further consideration and research.

  7. 5. Ultrastructural Aspects of Pulp Fibers as Studied by Dynamic FT-IR Spectroscopy

    Författare :Margaretha Åkerholm; KTH; []
    Nyckelord :cellulose; cooperation; crystallinity; dynamic test; glucomannan; hardwood; holocellulose; humidity; infrared spectroscopy; kraft pulp; lignin; mechanical pulp; orientation; polarised light; softwood; strain; sulphite pulp; viscoelasticity; xylan;

    Sammanfattning : Dynamic (or 2D) FT-IR spectroscopy in combination withpolarized IR irradiation has been used in this work to studywood polymer orientation and interactions on theultrastructural level in wood fibers in the native state aswell as the effects of different pulping processes. The woodpolymer interactions were studied under both dry and humidconditions. LÄS MER
