Harassment Origin for Kinematic Substructures in Dwarf Elliptical Galaxies? [PDF]

open access: yes, 2005
We have run high resolution N-body models simulating the encounter of a dwarf galaxy with a bright elliptical galaxy. The dwarf absorbs orbital angular momentum and shows counter-rotating features in the external regions of the galaxy.

Room reflections and constancy in speech-like sounds: within-band effects [PDF]

open access: yes, 2010
The experiment asks whether constancy in hearing precedes or follows grouping. Listeners heard speech-like sounds comprising 8 auditory-filter shaped noise-bands that had temporal envelopes corresponding to those arising in these filters when a speech ...

Full and half-wavelength ultrasonic percussive drills [PDF]

open access: yes, 2018
Ultrasonic-percussive drills are a leading technology for small rock drilling applications where power and weight-on-bit are at a premium. The concept uses ultrasonic vibrations to excite an oscillatory motion in a free-mass, which then delivers ...
