This study addresses the old question of whether the timbre of isolated piano tones can be audibly varied independently of their hammer velocities — only through the type of touch. A large amount of single piano tones were played with two prototypical types of touch: depressing the keys with the finger initially resting on the key surface (pressed), and hitting the keys from a certain distance ...

Previous works have shown that a combination of digital waveguide and signal models allows a perfect resynthesis of the sound generated by a string struck by a hammer. In particular the non-linear behavior of the hammer/string interaction is well reproduced. However, in an acoustic piano, two or three strings are struck by the same hammer, and the characteristics of the strings and the hammers ...

Measurements of the frequency response of head impact points on the exterior and the interior of a car were used to characterize the dynamic behavior of the object that was struck. These points were then arranged in a hierarchy of increasing stiffness. Thirty-two cases in which the distribution of injury to the brain had been recorded were grouped according to the stiffness of the object struck...

INTRODUCTION We report the case of a man who sustained a craniofacial injury after spontaneous lateral airbag deployment resulting in his face being struck by a car sunshade. This highlights the potential damage that can be caused by any object placed between a lateral airbag and a car occupant. CASE PRESENTATION We report the case of a 33-year-old Caucasian man who was the driver in a fronta...

Effects of nucleon-nucleon correlations on exclusive (e, ep) reactions on closed-shell nuclei leading to single-hole states are studied using O(e, ep)N (6.32 MeV, 3/2) as an example. The quasi-hole wave function, calculated from the overlap of translationally invariant many-body variational wave functions containing realistic spatial, spin and isospin correlations, seems to describe the initial...
