The paper summarizes experiences of development and use of interactive software for computer aided design of control systems. Different principles for interaction with users having wide ranges of experiences and knowledge are discussed. A comprehensive set of packages for modeling, identification, analysis, simulation, and design are described. Problems associated with structuring, portability, ma

Efter att ha utvärderat olika projekt, som utförts inom den svenska regeringens storstadssatsning under åren 1999- 2004 i Malmö, anser vi oss kunna dra några generella slutsatser om vad som karaktäriserar framgångsrika metoder för att åstadkomma integration. Viktigast är att kommunikationskanaler öppnas i vilka information får flöda i alla riktningar. Men för att detta flöde skall bli verkligt för

In our experience, doctoral supervision seminars and training (and associated literature) focus the supervisor-student relationship to an extent largely leaving aspects of learning, enculturation and subject discipline aside. In 2006-2008 we therefore developed and implemented a 3-week programme compulsory for new primary research supervisors (docent degree) with a wider scope, at the faculties En

We propose here a new procedure for output feedback design for systems with nonlinearities satisfying quadratic constraints. It provides an alternative for the classical observer-based design and relies on transformation of the closed-loop system with a dynamic controller of particular structure into a special block form. We present two sets of sufficient conditions for stability of the transforme

Sustainability science needs new methods which allow integration of knowledge across disciplines and scales. This paper suggests an approach to conceptualize problems of unsustainability by embedding the Drivers-Pressure-State-Impact-Response (DPSIR) scheme within a multilevel institutional framework represented by Torsten Hägerstrand’s system of nested domains. The proposed taxonomy assists to de

We calculate the spectral function of the half-filled two-dimensional Hubbard model with realistic hopping integrals for Sr2CuO2Cl2 within the dynamical mean-field theory at finite temperatures. It is shown that precursor effects of incommensurate spin dynamics lead to an incoherent broadening of the quasiparticle peaks on an energy scale that depends on local spin order. This might serve as an in

Two different rainfall-runoff models are applied to river basins in northern Sweden and Finland to study the effect of changed climate on peak flows. Hypothetical meteorological data series are constructed by increasing observed values by given amounts and fractions. In a Swedish moderately large basin snowmelt and daily precipitation were considered, and in two small Finnish basins, hourly precip
