This paper presents a new tuning method based on model parameters identified in closed-loop. For classical controllers such as PI(D) controllers a large number of simple tuning methods for various application areas exist. However, when it comes to designing a generalised predictive controller (GPC) four parameters have to be specified. To choose those parameters is not a trivial task since they are not directly related to control or regulation performance. The presented tuning method exploits model-parameters to select suitable controller parameters. Additionally, a Rhinehart filter is incorporated in the design to decrease the impact of noise, therefore, a fifth parameter has to be optimised. The proposed method has been tested in simulation and on a real system.
An important aspect of system support for mobile computing involves alleviating the issues related to programming the underlying distributed system. Our approach to dealing with these issues is by means of programming...

A case study on the simulation of a local area network (LAN) that has been used at Vrije Universiteit Brissel (VUB) and the University of Bern to illustrate evolution of object-oriented programs, is reported. The study is intended to illustrate modeling support for software evolution. The case consists of an initial version of the simulation program and a series of changes in the specification that require it to evolve. The evolution of the program corresponds to a series of four consecutive requirements at the level of the LAN, which must be incorporated into the simulation program.
Dynamic symbolic execution (DSE) is a powerful method for path exploration during hybrid fuzzing and automatic bug detection. We propose security predicates to effectively detect undefined behavior and memory access v...

A crosscut language is used to describe at which points an aspect crosscuts a program. An important issue is how these points can be captured using the crosscut language without introducing tight coupling between the aspect and the program. Such tight coupling harms the evolvability of the program and the reusability of the aspect. Current pattern-based capturing already offers a certain decoupling between aspects and the program but it may still suffer from what we call the arranged pattern problem. In this paper, we discuss this problem and present a logic-based crosscut language from which we distill what language features are beneficial to avoid this problem.
