Abstract. There has been much research on the design of Groupware, its potential benefits and the methods used to develop systems to support groups. However, in many real life case...
Distributed systems are typically designed for scale and performance first, which makes it difficult to add security later without affecting the original properties. This paper ...
In this work, a systematic approach to plant-wide control design is proposed. The method combines ingredients from process networks, thermodynamics and systems theory to derive ro...
