2. 1. On Reverberation Enhancement in Auditoria

   Author : Peter Svensson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active sound field control; room acoustics; reverberation enhancement; listening tests; subjective effects; sound-reinforcement; feedback systems; feedback control; computer modelling of acoustics in enclosures; modulation; electro acoustics; time-varying filters;

   Abstract : The analysis of electroacoustic systems for reverberation enhancement in auditoria is the topic of this thesis. Such systems have been developed since the 50's and been commercially available since then as well. During the 80's several new system ideas have been presented but there are still some open questions that are addressed here. READ MORE

4. 2. Studies on identification of time-variant and time-varying nonlinear systems

   Author : Anders Nordsjö; KTH; []
   Keywords : ;

   Abstract : This thesis addresses same aspects of nonlinear systemidentification. In par ticular, it is assumed that theconsidered systems can be described by the Wiener model whichconsists of a dynamit linear part followed by a nonbnear partor the Haxnmerstein model in which the order of these twoblocks is reversed.

5. 3. Input-Output Stability Analysis of Networked Control Systems

   Author : Johannes Nygren; Kristiaan Pelckmans; Torkel Glad; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; L2-stability; quantization; delay; packet dropouts; switching systems; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Abstract : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). READ MORE

   Author : José Araújo; Karl H. Johansson; Jan Lunze; KTH; []
   Keywords : wireless networked control systems; NCS; wireless communications; control; distributed reconfiguration; resilient; fault-tolerant control; IEEE 802.15.4; resource-aware; WNCS; aperiodic control; event-triggered; self-triggered; event-based; co-simulator; estimation; GISOO; MAC; scheduling; routing; RPL; delay; out-of-order communications; CPS; Cyber Physical Systems; Wireless Cyber Physical Systems; Wireless Cyber Physical Control Systems; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Networked control over wireless networks is of growing importance in many application domains such as industrial control, building automation and transportation systems. Wide deployment however, requires systematic design tools to enable efficient resource usage while guaranteeing close-loop control performance. READ MORE

7. 5. Analysis of the Age of Information in Status Update Systems

   Author : Antzela Kosta; Vangelis Angelakis; Nikolaos Pappas; Dán György; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Rapid advances in wireless technology have taken us towards a pervasively connected world in which a vast array of wireless devices, from mobile phones to environmental sensors, seamlessly communicate with each other. In some of these systems the freshness of the transmitted information is of high importance. READ MORE
