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

Popular Abstract in Swedish Målsättningen i denna avhandling är att identifiera funktionen hos COMP (Cartilage Oligomeric Matrix Protein). Detta protein finns framförallt i brosk och sena. Dessa vävnader tillhör bindväven och har till funktion att ta upp och fördela belastning, utgöra ett skydd och förmedla transport av olika ämnen. De är uppbyggda av ett fåtal celler inbäddade i en dominerande exConnective tissues contain a prominent extracellular matrix that provides mechanical and physical properties. This extracellular matrix contains as a major constituent a network of collagen fibres. These are composed of collagen fibrils, which in turn are assembled from many collagen molecules aligned parallel to each other. Several proteins, e.g. collagens, leucine-rich repeat proteins and thromb

Concepts of cognitive radio are yet in an early stage of development. They aim at improving the efficiency of spectrum utilization by exploiting locally and temporally vacant parts of the spectrum. When hierarchical spectrum access is considered, secondary users are authorized to use spectrum white spaces on a non-interfering basis, where minimal impact on the primary systems has to be ensured. GF

Based on a neuroscientific hypothesis, this paper explores the possibility of an ‘inner world’ based on internal simulation of perception. We present three sets of experiments with a possible minimal model, using a simulated Khepera robot controlled by a simple recurrent connectionist network. Using an evolutionary algorithm the robots are trained on increasingly complex tasks. In the first experi

Abstract in Danish Kapitlet viser først gennem en historisk analyse, at det er et relativt nyt fænomen, at de pårørende til mennesker, som trænger til hjælp i det danske sundhedssystem, på hospitalet, på plejehjemmet, i eget hjem og alle andre steder, beskrives og tænkes som en del af sundhedsvæsnet. Herefter gøres analytiske nedslag på hospitalet, plejehjemmet og i hjemmeplejen mhp. at se, hvorda
