To make the strange familiar: And to make the familiar strange

Through the making of courses in Rehabilitation engineering entirely over the Internet, Certec has pedagogically achieved three things. The most obvious is that our education has become more accessible for disabled students. Not so obvious was the effects that came from making the familiar strange when we were transferring to the net: It was impossible to invent a ‘net-pedagogy’ by doing anything

Feedback Control Design for the 3-state Moore-Greitzer Compressor Model

The well-known and commonly accepted finite dimensional model qualitatively describing surge instabilities in centrifugal (and axial) compressors is considered. The problem of global output feedback stabilization for it is solved. The solution relies on two new criteria for global stability proposed for a class of nonlinear systems exploiting quadratic constraints for infinite sector nonlinearitie

Structural reliability according to Eurocodes in serviceability limit state

The current study aims to investigate the reliability for serviceability design for flexural members made of different materials (steel, concrete and timber) according to the specifications of the current versions of Eurocodes. Second-order reliability method is applied to determine the reliability index for different design situations for simply supported beams subjected to bending. The character

Biogas production from crop residues on a farm-scale level: Scale, choice of substrate and utilisation rate most important parameters for financial feasibility

Anaerobic digestion would enable the energy potential of agricultural crop residues such as ley crops, sugar beet tops and straw to be harnessed in Sweden. These residues are so spread out that full utilisation of the potential by centralised slurry-based technology is difficult, its appearing that simple but effective high-solids reactor systems have a better chance of being economically viable o

Is the Hierarchical Structure of Articles 31 and 32 of the Vienna Convention Real or Not? Interpreting the Rules of Interpretation

In the practice of modern international law, if a certain understanding is advanced as the correct interpretation of a treaty provision, the proposition is assessed using the rules of interpretation laid down in the 1969 Vienna Convention on the Law of Treaties, Articles 31–33. This article is concerned with the relationship held in such an interpretation process between the preparatory work of a
