2. 1. Being Multisituated : Characterizing laptoping in networked situations

   Author : Tomas Lindroth; Magnus Bergquist; Ulrika Lundh Snis; Högskolan Väst; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Laptoping; laptoper; interaction order; actor-network theory; networked situation; multisituationism.; Informatik; Informatics; laptoping; laptoper; interaction order; actor-network theory; networked situation; multisituation;

   Abstract : During the last 30 years mobile IT has gone from being an exotic ingredient to an everyday artifact. This thesis presents an ethnographic study of laptop use in a university setting. The thesis concludes that it is no longer enough to describe the use of portable IT as an activity in its own right, i.e. READ MORE

4. 2. 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

5. 3. On Distributed Optimization in Networked Systems

   Author : Björn Johansson; Mikael Johansson; Asuman Ozdaglar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; resource allocation; networked systems; peer-to-peer; distributed optimization; Telecommunication; Telekommunikation; Automatic control; Reglerteknik;

   Abstract : Numerous control and decision problems in networked systems can be posed as optimization problems. Examples include the framework of network utility maximization for resource allocation in communication networks, multi-agent coordination in robotics, and collaborative estimation in wireless sensor networks (WSNs).

6. 4. Optimizing Networked Systems and Inverse Optimal Control

   Author : Han Zhang; Xiaoming Hu; Elias Jarlebring; Yiguang Hong; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Networked systems; energy optimal consensus control; semi-definite programming; distributed optimization; inverse optimal control; Mathematics; Matematik;

   Abstract : This thesis is concerned with the problems of optimizing networked systems, including designing a distributed energy optimal consensus controller for homogeneous networked linear systems, maximizing the algebraic connectivity of a network by projected saddle point dynamics. In addition, the inverse optimal control problems for discrete-time finite time-horizon Linear Quadratic Regulators (LQRs) are considered. READ MORE

7. 5. Compensating for Unreliable Communication Links in Networked Control Systems

   Author : Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

   Abstract : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. READ MORE
