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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Farhad Farokhi; KTH.; KTH.; [2014]
    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

  2. 2. Infinite-state Stochastic and Parameterized Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Noomene Ben Henda; Uppsala universitet.; Uppsala universitet.; [2008]
    Keywords : program verification; model checking; stochastic games; infinite-state systems; Markov chains; reachability; repeated reachability; parameterized systems; approximation; safety; tree systems;

    Abstract : A major current challenge consists in extending formal methods in order to handle infinite-state systems. Infiniteness stems from the fact that the system operates on unbounded data structure such as stacks, queues, clocks, integers; as well as parameterization. READ MORE

  3. 3. Timing Analysis of Distributed Embedded Systems with Stochastic Workload and Realiability Constraints

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Bogdan Tanasa; Linköpings universitet.; Linköpings universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; perfomance analysis; real-time systems; distributed systems; fault tolerance; probabilistic analysis;

    Abstract : Today's distributed embedded systems are exposed to large variations in workload due to complex software applications and sophisticated hardware platforms. Examples of such systems are automotive and avionics applications.The tasks running on computational units have variable execution times. READ MORE

  4. 4. Interacting Particle Systems: Percolation, Stochastic Domination and Randomly Evolving Environments

    University dissertation from Chalmers University of Technology

  5. 5. Active Resource Management in Middleware and Service-oriented Architectures

    University dissertation from Department of Communication Systems, Lund University

    Author : Niklas Widell; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; Intelligent Networks; TINA; web systems; distributed systems; resource allocation; stochastic optimization; simulation models; performance analysis; overload control; load balancing;

    Abstract : In this thesis, we study load balancing and overload control in two distributed architectures: Distributed Object Computing (DOC) systems and Services-oriented Architecture (SOA) systems. While DOC and SOA have differences in terms of implementation, they are similar from a performance viewpoint. READ MORE
