2. 1. Controllability of Complex Networks at Minimum Cost

   Author : Gustav Lindmark; Claudio Altafini; Anders Helmersson; Franco Garofalo; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The control-theoretic notion of controllability captures the ability to guide a system toward a desired state with a suitable choice of inputs. Controllability of complex networks such as traffic networks, gene regulatory networks, power grids etc. can for instance enable efficient operation or entirely new applicative possibilities.

4. 2. District heat production under different environmental and social cost scenarios

   Author : Nguyen Le Truong; Leif Gustavsson; André Faaij; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heat production; primary energy use; minimum-cost system; co-production;

   Abstract : District heat production systems (DHSs) are normally designed to meet the heat demand of customers at a minimum cost whilst fulfilling local and national regulations. Various factors influence the choice of district heat production units in a minimum-cost system. READ MORE

5. 3. On Application Oriented Experiment Design for Closed-loop System Identification

   Author : Afrooz Ebadat; Bo Wahlberg; Torsten Söderström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; closed-loop identification; experiment design for identification;

   Abstract : System identification concerns how to construct mathematical models of dynamic systems based on experimental data. A very important application of system identification is in model-based control design. In such applications it is often possible to externally excite the system during the data collection experiment. READ MORE

6. 4. On Some Combinatorial Optimization Problems : Algorithms and Complexity

   Author : Hannes Uppman; Peter Jonsson; Christer Bäckström; Ulf Nilsson; Stanislav Živný; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational complexity; optimization; constraint satisfaction problem;

   Abstract : This thesis is about the computational complexity of several classes of combinatorial optimization problems, all related to the constraint satisfaction problems.A constraint language consists of a domain and a set of relations on the domain. For each such language there is a constraint satisfaction problem (CSP). READ MORE

7. 5. Security of Time Synchronization for PMU-based Power System State Estimation: Vulnerabilities and Countermeasures

   Author : Ezzeldin Shereen; György Dán; Joe H. Chow; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phasor measurements unit; Time synchronization; Power system state estimation; Network Security; Time synchronization attacks; Precision time protocol; Machine learning; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Phasor Measurement Units (PMUs) constitute an emerging technology that is essential for various smart grid applications such as phase angle monitoring, power oscillation damping, fault localization, and linear state estimation. To obtain precise PMU measurements of voltage and current phasors, time synchronization in the order of 1 microsecond is typically required. READ MORE
