E. Bach, following an idea of T. Itoh, has shown how to build a small set of numbers modulo a prime p such that at least one element of this set is a generator of Z/pZ. E. Bach suggests also that at least half of his set should be generators. We show here that a slight variant of this set can indeed be made to contain a ratio of primitive roots as close to 1 as necessary. In particular we prese...

In his most recent contribution to an important and well-framed series of papers on auditory grouping and the perception of polyphonic music, David Huron seeks further evidence for his working hypothesis that J.S. Bach controls the employment of perfect consonances by desynchronizing their onsets, thereby inhibiting the perceptual fusion of polyphonic voices. However the more novel contribution...

We used ALOS InSAR images to study land surface deformation over the Crandall Canyon mine in Utah, which collapsed on 6 August 2007 and killed six miners. The collapse was registered as a ML 3.9 seismic event. An InSAR image spanning the time of the collapse shows 25–30 cm surface subsidence over the mine. We used distributed dislocation sources to model the deformation field, and found that a ...

This paper describes the participation of INSA Lyon and UNI Passau at the PAN 2017 Author Profiling task. Given the language and tweets from an author, the goal is to predict his/her gender and language variety. We consider two strategies : a "loose" classification that learns one predictive model for the gender and another one for the variety, and a "successive" classification that first predi...

Motivation This paper describes a Cognitive Systems Engineering (CSE) practitioner’s approach to the design and implementation of a C2 system, focussing on how the CSE approach guided the system’s design features. Originality/Value – The VAPS project was built as a concept demonstrator to investigate the efficacy of a CSE approach to building C2 systems. Research Approach The project team adopt...
