  2. 11. Detection for multiple input multiple output channels : analysis of sphere decoding and semidefinite relaxation

    Author : Joakim Jaldén; Björn Ottersten; Zhi-Quan Luo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunications; MIMO; Detection; Sphere Decoder; Semidefinite Relaxation; Telecommunication; Telekommunikation;

    Abstract : The problem of detecting a vector of symbols, drawn from a finite alphabet and transmitted over a multiple-input multiple-output (MIMO) channel with Gaussian noise, is of central importance in digital communications and is encountered in several different applications. Examples include, but are not limited to; detection of symbols spatially multiplexed over a multiple-antenna channel and the multiuser detection problem in a code division multiple access (CDMA) system.

  4. 12. On integrated modularization in heavy-duty truck architecting

    Author : David Williamsson; Ulf Sellgren; Anders Söderberg; Johan Malmqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modularization; Module; Product Architecture; Cyber-Physical System; Machine Design; Maskinkonstruktion;

    Abstract : Road transports face increasing challenges with respect to safety, legislations on lower emissions and traffic congestion, as well as numerous business challenges related to paradigm shifts in technology, tightened delivery times and cost constraints. Combination of truck electrification and automation may be utilized to address some of these issues. READ MORE

  5. 13. Perspectives on Modeling and Simulation of Urban Systems with Multiple Actors and Subsystems

    Author : Elhabib Moustaid; Sebastiaan Meijer; Gunnar Flötteröd; S Rajagopalan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation Modeling; Urban Systems; Expert Knowledge; Complexity Science; Mathematical Modeling; Second Order Effects.; Simulering och modellering; urbana system; expertkunskap; Komplexitetsvetenskap; matematisk modellering; andra graden effekt; Teknik och hälsa; Technology and Health;

    Abstract : Cities are the spaces of the interaction between social, physical, political, and economic entities, which makes planning and intervening in such systems difficult. Urban systems are complex adaptive systems in that their behaviours are often the result of the interaction of their components. READ MORE

  6. 14. Specification Decomposition and Formal Behavior Generation in Multi-Robot Systems

    Author : Philipp Schillinger; Dimos V. Dimarogonas; Daniele Magazzeni; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ltl; robot; robotics; multi-agent; behavior synthesis; formal methods; decomposition; high-level planning; multi-objective search; resource constraints; Electrical Engineering; Elektro- och systemteknik;

    Abstract : While autonomous robot systems are becoming increasingly common, their usage is still mostly limited to rather simple tasks. This primarily results from the need for manually programming the execution plans of the robots. Instead, as shown in this thesis, their behavior can be automatically generated from a given goal specification. READ MORE

  7. 15. Specification Decomposition and Formal Behavior Generation in Multi-Robot Systems

    Author : Philipp Schillinger; Dimos V. Dimarogonas; Mathias Bürger; Stephen L. Smith; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Robot Systems; Linear Temporal Logics; LTL; Robotics; Behavior Synthesis; Constrained Planning; Planning under Uncertainty; Multi-Agent Planning; Task Allocation; Mission Decomposition; Formal Methods; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Autonomous robot systems are becoming increasingly common in service applications and industrial scenarios. However, their use is still mostly limited to rather simple tasks. This primarily results from the considerable effort that is required to manually program the execution plans of the robots. READ MORE
