  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. Mobile robot navigation using non-contact sensors

    Författare :Johan Forsberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis concerns localization and control of mobile robots using range measurements from optronic sensors, in particular scanning time-of-flight lasers. The thesis covers the localization algorithms, on-line sensor calibration and tele-operation for semi-autonomous control of mobile robots. LÄS MER

  4. 3. Assisted Tele-Remote Control of Wheel Loaders in Underground Mining

    Författare :Siddharth Dadhich; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Tele-remote operation of mobile earth-moving machines in underground mines supported byoperator assistance functions is attractive for safety and productivity reasons. This way, operatorscan avoid hazardous underground environments with poor air quality and the productivitycan, in principle, be improved by saving the time required to commute drivers to and fromthe operational areas.

  5. 4. Att tänka det tekniska : En studie i Derridas teknikfilosofi

    Författare :Björn Sjöstrand; Sharon Rider; Hans Ruin; Björn Thorsteinsson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Derrida; phenomenology; deconstruction; technicity; technology; tele-technology; media; ethics; politics; religion;

    Sammanfattning : How should we understand the relations between human beings and technology? Where does technology end and where does the human being begin? How should we understand the relation between thinking and technology? These and related questions have been increasingly salient during the last decades. The aim of this study is to provide an outline of a philosophy of technology in the work of a major contemporary philosopher: Jacques Derrida. LÄS MER

  7. 5. Reactive navigation of an autonomous vehicle in underground mines

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mobile Robots; Computer science; Datavetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : In most underground mines, LHD (Load-Haul-Dump) vehicles are used to transportore from the stope or muck-pile to a dumping point, and are typically operated by a human who is sitting on-board the vehicle. Generally, an underground mine does not offer the best working environment for humans, and the job of an LHD operator can be characterised as Three D: Dangerous, Dirty and Dull. LÄS MER
