    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrolyte solutions; activity coefficient; osmotic coefficient; freezing point depression; boiling point elevation; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. LÄS MER

  3. 2. Resource-Constrained Multi-Agent Control Systems: Dynamic Event-triggering, Input Saturation, and Connectivity Preservation

    Författare :Xinlei Yi; Karl H. Johansson; Lihua Xie; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Consensus; Connectivity; Dynamic event-triggered control; Formation control; Input saturation; Multi-agent systems; Self-triggered control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : 978-91-7729-579-2A multi-agent system consists of multiple agents cooperating to achieve a common objective through local interactions. An important problem is how to reduce the amount of information exchanged, since agents in practice only have limited energy and communication resources. LÄS MER

  4. 3. Distributed Optimization and Control : Primal--Dual, Online, and Event-Triggered Algorithms

    Författare :Xinlei Yi; Karl H. Johansson; Dimos V. Dimarogonas; John S. Baras; Antonis Papachristodoulou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed nonconvex optimization; distributed online convex optimization; distributed event-triggered control; primal-dual algorithm; stochastic gradient descent; zeroth-order algorithm; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In distributed optimization and control, each network node performs local computation based on its own information and information received from its neighbors through a communication network to achieve a global objective. Although many distributed optimization and control algorithms have been proposed, core theoretical problems with important practical relevance remain. LÄS MER
