In this paper a robust design process is introduced for a scalar model reference adaptive control (MRAC) algorithm. Three different types of MRAC control rules are reviewed and analysed in the frequency domain. A design process for MRAC is given within the range of plant settling times 0.01-100 seconds which is relevant for a wide range of mechanical systems. By using this design method the MRA...

This paper describes a mobile implementation of song filtering using rhythmic interaction. A user taps the screen or shakes the device (sensed through an accelerometer) at the tempo of a particular song in order to listen to it. We use the variability in beat frequency to display ambiguity to allow users to adjust their actions based on the given feedback. The results of a pilot study for a sim...

Probabilistic seismic hazard analysis [PSHA, e.g., Cornell (1968); Anderson and Trifunac (1978); McGuire (1977); McGuire (1995)], typically used in risk assessment and hazard mitigation, has so far relied on ground motion prediction equations (GMPEs), also called attenuation relations [e.g., the next generation attenuation relations or NGA by Campbell and Bozorgnia (2008); Chiou and Youngs (200...

Reversible clusters of nanobiocatalysts are developed via non-covalent interaction among enzyme-bound iron oxide magnetic nanoparticles. Dissociation of the clusters by shaking during biotransformation enables high catalytic performance, and re-clustering by stopping shaking after reaction allows for easy magnetic separation. The novel concept is demonstrated with alcohol dehydrogenase RDR for ...

BACKGROUND The donkey has a reputation for stoicism and its behavioural repertoire in clinical contexts is under-reported. Lack of understanding of the norms of donkey behaviour and how it may vary over time can compromise use of behavioural measures as indicators of pain or emotional state. The objective of this study was to find out whether the behaviour of working donkeys was influenced by g...

This paper employs one-dimensional numerical ground response analysis models to investigate seismic response of shallow cohesive and non-cohesive soil deposits on vertical propagation of horizontal shear waves. Soil response is modelled by traditional equivalent-linear (EL) frequency-domain analysis using DEEPSOIL software and nonlinear (NL) time-domain analysis using OPENSEES software. The ana...
