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 H-L Grafchart fit the models defined in the forthcoming ISA batch control standard SP88. A simulated batch process cell s

Introduction: Mammography is one of the most common X-ray examinations although it is well-known that the anatomical background of the breast is the main obstacle when it comes to detection of breast lesions with this method. Tomosynthesis is a three-dimensional radiographic technique which, to a large extent, can suppress the confounding effect of the anatomical background. Tomosynthesis is a str
Popular Abstract in Swedish I den här avhandlingen studeras problem från två områden, medicin och kommunikation. Den medicinska delen behandlar skattning av Händelserelaterade signaler (Event-related Potentials, ERP). Dessa signal uppkomer i hjärnan då försökspersonen stimuleras via yttre påverkan, t.ex ljusblinkning, pipljud eller elektrisk stimulering av huden. De händelserelaterade signalerna kThis thesis consists of five parts in which problems in two fields, medical and telecommunication, have been studied. In the first part, a prediction algorithm, the Prony method, for estimation of frequencies and damping factors of sinusiods is developed for a coloured noise disturbance. The method is applied to estimating a single Event-Related Potential, sERP, and the estimation principle is ev
There is often a need to predict the impact of alterations in one variable on another variable. This is especially the case in cancer research, where much effort has been made to carry out large-scale gene expression screening by microarray techniques. However, the causes of this variability from one cancer to another and from one gene to another often remain unknown. In this study we present a sy
The article adresses the issue of platonic philosophy in the writings of Tertullian. That this Latin Church Father was mainly influenced by Stoicism is a commonplace. Yet, the amount of direct and indirect reception of platonism should not be underestimated. It is further presupposed by the author that Tertullian does not deserve the reputation as an enemy of philosophy, which is the conventional
Föreliggande rapport behandlar den strategiska forskningsmiljön The Middle East in the Contemporary World (MECW), vid Lunds universitet. Rapporten utgör delrapport II inom ramen för ett projektarbete som deltagarna i programmet Morgondagens forskningsledare genomför 2011–20122. Syftet med projektet är att få en fördjupad förståelse för hur komplexa och strategiskt viktiga forskningsmiljöer kan str
This dissertation examines people’s understanding of and action according to norms. Two models are distinguished: a cognitive and a non-cognitive model. The cognitive model is characterized by requiring for people to understand norms and each other, and to act accordingly, that they have higher-order mental states whose propositional contents refer to the mental states of others and from these i
