The costs of ignoring species detectability on functional diversity estimation
(American Ornithologists' Union, 2021-02)
Functional diversity (FD) approaches have been increasingly used to understand ecosystem functioning in bird communities. These approaches typically rely on the assumption that species are perfectly detected in the field, ...
Test for Global Identifiability for Nonlinear Model Structures
(Planta Piloto de Ingeniería Química, 2000-12)
n the present work an algorithm for testing global identifiability for a wide class of nonlinear model structures with bounded signals is presented. The objective functional applied for parameter estimation is assumed to ...
On the scalability of supply cost for demand management in the smart grid
(Institute of Electrical and Electronics Engineers, 2022-04)
Demand side management focuses on flattening the demand profile, reducing network losses, costly investments in network infrastructure and generation capacity. The supplier pursues a profit for the service it provides. In ...
Lighting pollution, the benefit/cost approach
(Znack Publishing House, 2002-05)
One of the urban lighting objectives is to extend people’s activities during night. In this case lighting is linked with functions as visibility, safety, security and visual
appearance of the surroundings. Considering ...
Benefit and cost curves for typical pollination mutualisms
(Ecological Society of America, 2010-05)
Mutualisms provide benefits to interacting species, but they also involve costs. If costs come to exceed benefits as population density or the frequency of encounters between species increases, the interaction will no ...
Computational cost of isogeometric multi-frontal solvers on parallel distributed memory machines
(Elsevier Science Sa, 2015-02)
This paper derives theoretical estimates of the computational cost for isogeometric multi-frontal direct solver executed on parallel distributed memory machines. We show theoretically that for the Cp-1 global continuity ...
What can a low-cost fish-finder tell us about the seabed?
(Academic Press Ltd - Elsevier Science Ltd, 2018-12)
Low-cost non-scientific echosounders are commonly used for safety and other non-scientific purposes. These echosounders routinely record data which are rarely processed for later use, but which could provide interesting ...
Harvesting contractor production and costs in forest plantations of Argentina, Brazil, and Uruguay
(Taylor and Francis Group, 2017-08-18)
Timber production from forest plantations has increased substantially in South America in the last few decades. The timber harvesting process is carried out mainly through logging contractors. This research developed ...
The true cost of maternal death: Individual tragedy impacts family, community and nations
(BioMed Central, 2015-06)
The death of a woman in pregnancy and childbirth is globally considered an individual tragedy and a human rights violation. Given the inequities in death that occur to marginalized, poor, and vulnerable women in low and ...
Assessment of the energy-related cost function over a range of walking speeds
(Springer Heidelberg, 2019-06)
Cost funtions are needed for calculation of muscle forces in musculoskeletal models. The behavior of the energy-related cost function, proposed by Praagman et al. (J Biomech 39(4):758?765, 2006. https://doi.org/10.1016/j ...
