This paper presents theory, algorithms, and validation results for system identification of continuous-time state-space models from finite input-output sequences. The algorithms developed are methods of subspace model identification and stochastic realization adapted to the continuous-time context. The resulting model can be decomposed into an input-output model and a stochastic innovations model.

We discuss modeling and analysis of real-time control systems subject to random time delays in the communication network. A new method for analysis of given control schemes is presented. The state of the network is modeled by a Markov chain and Lyapunov equations for the expected LQG performance are presented. An example that illustrates the results is given.

A spherical reference field is used to construct a digital holography system with a demonstrated resolution down to 228 line pairs per mm. The reference field origin from a GRIN lens placed 1mm from the illuminated object. This allows the use of a standard sensor to record the hologram with the required numerical aperture. The image is determined by evaluation of the Rayleigh-Sommerfeld diffraction i

The problem of analyzing heart rate variability in the presence of ectopic beats is revisited. Based on the IPFM model and the closely related heart timing signal, a new technique is introduced which corrects for the occasional presence of such beats. The correction technique, which involves the occurrence times of a certain number of beats preceding the ectopic, is computationally very efficient.

A bilinear system model of a continuous tank reactor from a biotechnology application (F. Mandenius et al., 1987) is studied. The concentrations of the substrate sugar and the product ethanol were measured on-line and utilized to control the flow-rate through the fermenter. The system can be integrated analytically making it possible to describe the reachable sets. Limited controllability is found

Knowing the droplets temperature is of great importance in spray-assisted combustion devices as it directly affects the droplet evaporation rate. This information helps optimizing the fuel/air mixture formation for the improvement of combustion devices. To measure the temperature of spray droplets, optical techniques such as Rainbow-Refractrometry (for point-wise) and the two-color LIF ratio therm

In this paper list decoding of convolutional codes is considered. List decoding is a very powerful, low complexity, non-backtracking decoding method that does not fully exploit the error correcting capability of the code. A correct path loss is a serious kind of error event that is typical for list decoding. An expurgated upper bound on the probability of correct path loss is derived for the ensem
