A simple event-based PID controller is presented. It is shown that it is possible to obtain large reductions in CPU utilization with only minor control performance degradation. Simulations on a double-tank process are presented.
The content of this report is a deliverable to the FP 7 project RUFUS (Rural future Networks) concerning the case studies made within the project. As a deliverable in a EU framework project it reports extensively on the methods and empirical data collected in the project’s case studies. The work has as an overarching motive to translate research findings into implications that are relevant for pol

This report presents the result of an initial step towards an interdisciplinary research partnership between the involved departments at Aleppo and Lund University. The initiator and main author, Dr. Ayman Hamadeh, visited Division of Packaging Logistics during the summer 2008. During that time the authors identified corrugator sequencing as a common research field and embarked on a joint explorat
Due to increased awareness of climate change and energy costs, well-insulated buildings have become more common. Furthermore, greater interest has been shown in using wood in building to produce more carbon dioxide-efficient houses. However, thicker thermal insulation in walls increases the risk of high relative humidity levels and the risk of mold-related damage in wood frame houses. This paper
This chapter explores the idea of community of practice in relation to Swedish educational development. Two authentic cases illustrate how faculty developers work together as a CoP to promote change within universities. The two cases and their results are scrutinized in relation to key features of CoP, where one case arguably came out stronger as a CoP mainly in terms of identity building. The tex
The paper presents a revised definition of the mean effective gain (MEG) of terminal antennas. It now includes the gain pattern of both the transmitting (BS) and receiving (MS) antennas, the path gain matrix as well as the joint angular power distributions of the two orthogonal polarizations at both ends. A closed form equation is provided followed by the analysis of some special cases and their p
