Spatially explicit capture-recapture models for relative density. [PDF]

Ecology
Spatially explicit capture–recapture (SECR) methods are used widely to estimate animal population density and related parameters. Maximum likelihood has been applied to two flavors of the SECR model—a full model that includes absolute density as a ...

Some aspects on geometric and matrix work-hardening characteristics of sintered cold forged copper alloy preforms [PDF]

Materials Research, 2013
Powder metallurgy (P/M) material subjected to plastic deformation results into densification, however the extended deformation would not only enhance the densification also supplements the strain hardening.

Experimental study on permeability characteristics of sandy gravel with high fines content

Yantu gongcheng xuebao, 2023
A series of tests are conducted on the permeability characteristics of sandy gravel with high fines content. It is found that the permeability coefficient of sandy gravel decreases with the increase of the particles less than 5 mm and the relative ...

Model Test of the Pullout Bearing Capacity of End-Bearing Torpedo Anchors

Journal of Marine Science and Engineering, 2022
Torpedo anchors (TAs) are regarded as one of the most efficient mooring solutions for taut mooring systems, and end-bearing TAs are a new type of TA that primarily relies on end-bearing plates at the tail to generate a pile-end resistance to improve ...

Estimating the functional form for the density dependence from life history data [PDF]

, 2008
Two contrasting approaches to the analysis of population dynamics are currently popular: demographic approaches where the associations between demographic rates and statistics summarizing the population dynamics are identified; and time series approaches
