  1. 21. Forward and Inverse Decision-Making in Adversarial, Cooperative, and Biologically-Inspired Dynamical Systems

    Författare :Inês de Miranda de Matos Lourenço; Bo Wahlberg; Karinne Ramirez-Amaro; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Decision-making is the mechanism of using available information to develop solutions to given problems by forming preferences, beliefs, or selecting courses of action amongst several alternatives. It is the main focus of a variety of scientific fields such as robotics, finances, and neuroscience. LÄS MER

  3. 22. Cognitive Radio Networks : Elements and Architectures

    Författare :Alexandru Popescu; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cognitive radio network management; spectrum access; multiconstrained routing optimization; multi-dimensional adaptation; middleware;

    Sammanfattning : As mobility and computing becomes ever more pervasive in society and business, the non-optimal use of radio resources has created many new challenges for telecommunication operators. Usage patterns of modern wireless handheld devices, such as smartphones and surfboards, have indicated that the signaling traffic generated is many times larger than at a traditional laptop. LÄS MER

  4. 23. On Fundamental Elements of Visual Navigation Systems

    Författare :Abujawad Rafid Siddiqui; J. Rafid Siddiqui; Sweden Karlskrona Blekinge Tekniska Högskola Institutionen för kommunikationssystem; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot navigation; localization; visual mapping; scene understanding; semantic mapping;

    Sammanfattning : Visual navigation is a ubiquitous yet complex task which is performed by many species for the purpose of survival. Although visual navigation is actively being studied within the robotics community, the determination of elemental constituents of a robust visual navigation system remains a challenge. LÄS MER

  5. 24. Selfish Dynamic Spectrum Access in Multichannel Wireless Networks : Complete and incomplete information analysis

    Författare :Ali Özyagci; Jens Zander; Alexandre Proutiere; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Game theory; Multichannel random access; Bayesian game; Nash equilibrium Heterogeneous channels; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : The increasing popularity and widespread deployment of wireless data systems fuel the increasing demand for more spectrum. On the other hand, various studies measuring spectrum utilization show that there is a huge variation in spectrum utilization at different times and locations. LÄS MER

  7. 25. Performance Analysis of Cognitive Radio Networks under Spectrum Sharing and Security Constraints

    Författare :Louis Sibomana; Zepernick Hans-Jürgen; Slimane Ben Slimane; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underlay cognitive radio networks; spectrum sharing constraints; physical layer security;

    Sammanfattning : The cognitive radio network (CRN) concept has been proposed as a solution to the growing demand and underutilization of the radio spectrum. To improve the radio spectrum utilization, CRN technology allows the coexistence of licensed and unlicensed systems over the same spectrum. LÄS MER
