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

   Författare :Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Real-Time Services in Packet-Switched Networks for Embedded Applications

   Författare :Xing Fan; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; embedded systems; real-time communication; packet-switching; swithed Ethernet; FCFS and EDF scheduling; schedulability analysis; active networking; protocol overhead; Computer science; Datalogi; Computer science; Datavetenskap;

   Sammanfattning : Embedded applications have become more and more complex, increasing the demands on the communication network. For reasons such as safety and usability, there are real-time constraints that must be met. Also, to offer high performance, network protocols should offer efficient user services aimed at specific types of communication. LÄS MER

4. 3. Active Resource Management in Middleware and Service-oriented Architectures

   Författare :Niklas Widell; Institutionen för elektro- och informationsteknik; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. Data management in control applications : a proposal based on active database systems

   Författare :Esa Falkenroth; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Active database management systems can provide general solutions to data management problems in control applications. This thesis describes how traditional control algorithms and high-level operations in a control system can be combined by using an embedded active object-relational database management system as middleware.

7. 5. Modelo para promoção da mobilidade urbana ativa por bicicleta: uma abordagem do design de serviços para o comportamento sustentável. (Model for promoting active urban mobility by bicycle: a service design approach for sustainable behaviour)

   Författare :Gheysa Prado; Universidade Federal do Parana; []
   Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bicycle; urban mobility; active mobility; design for sustainable behaviour; behaviour change; service design; sustainable urban mobility;

   Sammanfattning : The population growth associated with an accelerated urbanization process - with more than 50% global people living in cities - are weighting negatively on social and ambiental developing aspects. Among the compromised areas is the urban mobility, where the priority has been given to motorized ways of transports other than active mobility. LÄS MER
