The linear $H^infty$ control problem is stated for time-varying plant with arbitrary delays and discontinuous coefficients. The image representation of the plant is explicitly written and full solution to the suboptimal control problem is presented. Necessary and sufficient conditions for existence of a solution are derived from the abstract principle of maximum. No Riccati equations are used. The

The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. It is shown that it will be possible to discov

The paper presents how object-oriented sequential function charts can be used to implement a batch control recipe management system. Grafchart, a toolbox based on Grafcet, object-oriented programming ideas and High-level Petri nets, is presented. It is shown how the concepts of Grafchart fit the models defined in the ISA batch control standard ISA-S88.01. A simulated batch process cell scenario is

Numerous geometric problems in computer vision in- volve the solution of systems of polynomial equations. This is true for problems with minimal information, but also for finding stationary points for overdetermined problems. The state-of-the-art is based on the use of numerical linear algebra on the large but sparse co- efficient matrix that represents the expanded original equation set. In this

Purpose of this paper The purpose of this paper is to propose a framework for describing and analyzing misalignments in supply chain management, which relate to changes in supply chain structures, processes, and management components. Design/methodology/approach Based on the systems approach, a single-case study with embedded design including several embedded cases from the same supply chain was

Popular Abstract in Swedish Proteiners interaktioner med andra proteiner, med polymerer och med ytor har stor praktisk betydelse inom bland annat proteinrening, läkemedelsformulering och livsmedelsteknologi. Målet med detta arbete är att öka förståelsen för växelverkan mellan proteiner, mellan proteiner och polymerer samt mellan proteiner och ytor, särskilt beträffande de elektrostatiska krafternaInteractions of proteins with other proteins, with polymers and with surfaces are of great practical importance within for instance protein purification, drug delivery, and food technology. The aim of this work is to increase the understanding of protein-protein, protein-polyelectrolyte, and protein-surface interactions, particularly concerning the role of electrostatic interactions in these syste
