Maximum likelihood estimation of mortality and growth with individual variability from multiple length-frequency data

open access: yes, 2005
We consider estimation of mortality rates and growth parameters from length-frequency data of a fish stock and derive the underlying length distribution of the population and the catch when there is individual variability in the von Bertalanffy growth parameter L∞.

Effect of measurement method on an earmuff’s frequency response

open access: yesArchives of Acoustics, 2014
Light, medium and heavy earmuffs’ amplitude frequency response was measured using transmission loss technique with a microphone placed in subject’s ear (MIRE – microphone in real ear) and on an artificial test fixture (ATF). Measurements were conducted

Unit Root Tests: Results from some recent tests applied to select Indian macroeconomic variables [PDF]

open access: yes
Results from newly developed unit roots tests of ERS (1996), PN (1996), NP (2001) and LM (1994) are compared against their traditional counterparts (ADF, PP and KPSS) on select Indian macroeconomic data.

Acoustic performance of inlet multiple-pure-tone suppressors installed on NASA quiet engine C [PDF]

open access: yes
The length of multiple-pure-tone (MPT) treatment required to reasonably suppress the MPT's produced by a supersonic tip speed fan was defined. Other suppression, broadband, and blade passing frequency, which might be accomplished were also determined ...

A Conjugate-Cyclic-Autocorrelation Projection-Based Algorithm for Signal Parameter Estimation

open access: yesEURASIP Journal on Wireless Communications and Networking, 2006
A new algorithm to estimate amplitude, delay, phase, and frequency offset of a received signal is presented. The frequency-offset estimation is performed by maximizing, with respect to the conjugate cycle frequency, the projection of the measured ...
