This paper reports the work on implementing a parallel version of Pascal on a small scale multiprocessor computer. A few simple primitives were included to support parallel programming. The code generation, linking and loading procedures are described. An overview of the hardware is included. Finally some programming experience with the system is reported.
De senaste tjugo åren har många personer med utvecklingsstörning valt att flytta till egna lägenheter med olika former av assistans. För de flesta har det inneburit ett ökat personligt ansvar för olika uppgifter i hemmet. Några har klarat detta utan probl
Based on evidence from urban development projects in the city of Malmö, Sweden, I would like to discuss the idea that the success of the neoliberal utopia is based not in a clear break with its predecessor - social democracy – but in the appropriation, reworking and transformation of the social-democratic ideal to suit specific elite interests. The current institutionalisation of neoliberal planni
Theory for Adaptive Nonlinear Model Predictive Control is developed based on the relaxed dynamic programming inequality. The adaptivity in the controller lies in the choice of control horizon. The control horizon is chosen such that a variation of the relaxed dynamic programming inequality holds for all time steps along the closed loop trajectory. This provides guarantees for asymptotic stability
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
