In this paper, two brittle fracture problems are numerically simulated: the failure of a ceramic ring under centrifugal loading and crack branching in a PMMA strip. A three-dimensional finite element package in which cohesive elements are dynamically inser ...
After more than a century of research, the mechanisms underlying visual masking are still hotly debated. One key characteristic of masking is that variations in the stimulus onset asynchrony (SOA) between the target and the mask can lead to either monotoni ...

A novel active-RC biquad is presented which can be reconfigured as a polyphase filter for a low IF wireless receiver architecture, and as a lowpass filter for a zero IF wireless receiver architecture. A second order lowpass-polyphase reconfigurable filter ...
In this paper, we revisit wavelet theory starting from the representation of a scaling function as the convolution of a B-spline (the regular part of it) and a distribution (the irregular or residual part). This formulation leads to some new insights on wa ...
Structural dynamics in semi-quantum and quantum solids (Ne, H2 and D2) is reported, and compared to results in classical solids such as Ar. The structural dynamics is driven by excitation of the lowest Rydberg state of the NO impurity. The resulting charge ...
AB: The accurate prediction of near-source strong-ground motions in future earthquakes is a major challenge for seismologists and earthquake engineers. Such a prediction is however difficult, partly because ground motions are highly variable while the reas ...
In 1919 in an essay entitled Tradition and the Individual Talent T. S. Eliot stated that a poet “is not likely to know what is to be done unless he lives in what is not merely the present, but the present moment of the past, unless he is conscious, not of ...

In the context of sustainable development, building insulation represents a major concern as a means of increasing energy efficiency. In order to comply with new norms such as the Passive House standard, locations where load-bearing components must penetra ...
We report fast modulation (>30 GHz) in a SOI resonant cavity using integrated Bragg mirrors and a gate-all-around transistor as active element. Modulation depth >90% can be obtained in 12.5 μm long devices. ...
In this paper we describe the successful use of RE methods in a project at Procter and Gamble UK. We identify two main elements for this success. The first element is the combination of methods from P&G and academia (Adoption Methodology and Lightswitch). ...
