16.2.1 Density

ABAQUS Analysis User's Manual ... Density can be defined as a function of temperature and field variables; however, for all elements except acoustic, heat transfer, coupled temperature-displacement, and coupled thermal-electrical elements the density is a function of the initial values of temperature and field variables and changes in volume ...

20.3.1 Acoustic medium

The behavior of an acoustic medium is sometimes defined by its bulk modulus and a frequency-dependent “complex density,” .For use in ABAQUS/Standard this complex density must be converted to density, , and a volumetric drag coefficient, .Since the material density, , cannot be made a function of frequency in ABAQUS, only the frequency dependence of the imaginary part of the complex density ...

Estimating animal population density using

Nov 29, 2012 . Here, we focus on the nascent science of passive Acoustic Density estimation: methods to estimate population density or abundance based on detecting sounds naturally produced by animals. Acoustic Density estimation must not be seen as a panacea; however, as we show here, it is a fast-developing field with enormous potential.

A practical comparison of manual and autonomous

Apr 13, 2013 . Autonomous acoustic recorders are widely available and can provide a highly efficient method of species monitoring, especially when coupled with software to automate data processing. However, the adoption of these techniques is restricted by a lack of direct comparisons with existing manual field surveys.

Cetacean population density estimation from single

Jun 14, 2011 . Input distributions for source level, beam pattern, and whale depth are obtained from the literature. Acoustic propagation modeling is used to estimate transmission loss. Other inputs for density estimation are call rate, obtained from the literature, and false positive rate, obtained from manual analysis of a data sample.

Estimating minke whale (Balaenoptera

Hawaii, to estimate density during 12 d of recordings in early 2006. We converted the number of acoustic cues (i.e., boings) detected using signal processing software into a cue density by accounting for the false positive rate and probability of detection. The former was estimated by manual validation, the latter by applying

A spatial capture–recapture model to estimate call rate

In particular, acoustic SCR models deal with detections of animal vocalisations across an array of acoustic detectors. Previously published acoustic SCR methods either estimate call density (calls per unit space per unit time) rather than animal density itself, require an independently estimated call rate to estimate animal density, or discard ...
