Restoration Ecology: Two-Sex Dynamics and Cost Minimization [PDF]

open access: yes, 2013
We model a spatially detailed, two-sex population dynamics, to study the cost of ecological restoration. We assume that cost is proportional to the number of individuals introduced into a large habitat. We treat dispersal as homogeneous diffusion.

3-D Distributed Localization With Mixed Local Relative Measurements [PDF]

open access: yesIEEE Transactions on Signal Processing, 2020
This paper studies 3-D distributed network localization using mixed types of local relative measurements. Each node holds a local coordinate frame without a common orientation and can only measure one type of information (relative position, distance, relative bearing, angle, or ratio-of-distance measurements) about its neighboring nodes in its local ...

Local Percolation Probabilities for a Natural Sandstone

open access: yes, 1996
Local percolation probabilities are used to characterize the connectivity in porous and heterogeneous media. Together with local porosity distributions they allow to predict transport properties \cite{hil91d}.

Rescaling Relations between Two- and Three-dimensional Local Porosity Distributions for Natural and Artificial Porous Media

open access: yes, 1996
Local porosity distributions for a three-dimensional porous medium and local porosity distributions for a two-dimensional plane-section through the medium are generally different.

Free infinite divisibility for beta distributions and related ones [PDF]

open access: yes, 2014
We prove that many of beta, beta prime, gamma, inverse gamma, Student t- and ultraspherical distributions are freely infinitely divisible, but some of them are not. The latter negative result follows from a local property of probability density functions.

Explaining local-scale species distributions: relative contributions of spatial autocorrelation and landscape heterogeneity for an avian assemblage. [PDF]

open access: yesPLoS ONE, 2013
Understanding interactions between mobile species distributions and landcover characteristics remains an outstanding challenge in ecology. Multiple factors could explain species distributions including endogenous evolutionary traits leading to ...

River water temperature quantiles as thermal stress indicators: Case study in Switzerland

open access: yesEcological Indicators, 2021
The variability of the river water thermal regime has important consequences on the environment and aquatic habitat. In 25 independent and identically distributed stations in Switzerland, local frequency analysis is used to quantify extreme river ...

Investigating the Contact Responses of the Roller Cavity Surfaces in the Compressor Blade Rolling Process

open access: yesAdvances in Materials Science and Engineering, 2020
The investigation of the contact responses is the key for evaluating the local wear of dies in the plastic forming process. This paper investigated the contact load distributions and evolutions of the roller cavities in the compressor blade rolling ...
