The paper presents a feedback scheduling mechanism in the context of co-design of the scheduler and the control tasks. We are particularly interested in controllers where the execution time may change abruptly between different modes, such as in hybrid controllers. The proposed solution attempts to keep the CPU utilization at a high level, avoid overload, and distribute the computing resources eve
This paper presents a practical risk analysis method for critical, large-scale IT systems in an organisation. The method is based on reliability block diagram modelling and was adapted to fit the requirements of governmental organisations and to reduce the effort required to capture complex failure behaviour. Through the use of different failure categories the risk analysis can be simplified, the
This book is a collection of essays and articles on warfare, from Roman antiquity to the early modern era. Most articles are focused on medieval warfare, such as the battles of Hastings, Durben and Nicopolis, the myth of chivalry, the career of Joan of Arc, the Varangian guard, the Scanian campaign of 1452, the crusades, the tactics of the Burgundian army in the fifteenth century and the nuns' reb
Towards sustainability the implementation of Global Learning for Sustainable Development (GLSD) is crucial. A better understanding of how to – from a global didactic angle – establish globally genuine dialogues forming nuanced conceptions of sustainable development (SD) is necessary. Global teaching as well as global learning has to identify the challenges in various contexts for transdisciplinary
This paper will treat the development of a laboratory exercise indiscrete event control. Thehardware components are described as well as theinterface. The software is written entirely in Java, and thecontroller implementations are done in JGrafchart, which is alsobriefly described. The process is portable and flexible which haveshortened the development process and also simplifies future modificat
Wrap Your Troubles into Dreams, är ett praktikbaserat forskningsprojekt. Undersökningen berör stadsomvandlingsprocesser i Stockholmsområdet, speglade genom två politiska förhållningssätt gestaltat i staden: genomförandet av det funktionsseparerade Stockholms City (under 1960-talet) och de senaste decenniernas privatisering av stadsrummet. I forskningen har jag utgått från två platser som i motreakWrap Your Troubles into Dreams is a practice-based artistic research project. The study investigates city transformation processes in the Stockholm area, by viewing them through two political attitudes expressed in the city; the introduction of the function-separated Stockholm City area (during the 1960s) and the privatisation of urban space during the last few decades. I have based my research on
Abstract Due to developments in the last decades in the field of protein production, new technologies for bio-separation have evolved. Especially in the field of affinity chromatography, the search for new ligands is of great interest. Besides the antibodies used as affinity ligands, synthetic ligands were introduced. Textile dyes were a first group to be introduced but despite their selectivity a
