Constant-bandwidth supply for priority processing [PDF]

open access: yes2011 IEEE International Conference on Consumer Electronics (ICCE), 2011
Today's consumer electronic devices feature multiple applications which have to share scarcely available resources. We consider a priority-processing-based video application, which comprises multiple scalable video algorithms (SVAs) that are executed on a shared, virtual platform.

Wide-Bandwidth Constant-Beamwidth Acoustic Array [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1970
A linear broadside array can be made to have constant beamwidth over wide frequency ranges by using logarithmic element spacing and the proper filtering and combination of signals from the elements. Such an array is achieved by choosing the array size and linear element spacing to give the desired beamwidth and side-lobe suppression at the lowest ...
