  2. 1. Decentralized Control of Networked Systems : Information Asymmetries and Limitations

    Author : Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Decentralized Control; Limited Model Information; Transportation Systems; Sensor Scheduling;

    Abstract : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. READ MORE

  4. 2. Decentralized Application Security

    Author : Per Hallgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Decentralization; Homomorphic Encryption; Location-Based Services; Privacy;

    Abstract : On the internet today, everything is centralized. For most people, a single commercial entity owns the power to disclose all their personal emails. Most commonly your emails are only disclosed to you and your correspondent, but the power to choose who sees these emails is in fact not yours. READ MORE

  5. 3. Dynamic Adaptation in Industrial IoT Systems

    Author : An Ngoc Lam; Jerker Delsing; Øystein Haugen; Hartwig Baumgärtel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomic Computing; Industrial IoT; Self-adaptation; Semantic Interoperability; System of Systems; Cyberfysiska system; Cyber-Physical Systems;

    Abstract : The evolution of the current technological landscape has opened an emergent paradigm that enables interoperability between the digital and physical world, leading to a new generation of industrial systems. This new digitalization era marks the beginning of the fourth industrial revolution, usually referred to as "Industry 4.0". READ MORE

  6. 4. Decentralized Constrained Optimization: a Novel Convergence Analysis

    Author : Firooz Shahriari Mehr; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constrained optimization; Decentralized optimal transport; Distributed optimization; Multi-agent systems; Convergence analysis; Convex optimization;

    Abstract : One reason for the spectacular success of machine learning models is the appearance of large datasets. These datasets are often generated by different computational units or agents and cannot be processed on a single machine due to memory and computing limitations. READ MORE

  7. 5. Small-Scale Decentralized Energy Systems : optimization and performance analysis

    Author : Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

    Abstract : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. READ MORE
