Dynamic Model for LES Without Test Filtering: Quantifying the Accuracy of Taylor Series Approximations [PDF]

open access: yes, 2001
The dynamic model for large-eddy simulation (LES) of turbulent flows requires test filtering the resolved velocity fields in order to determine model coefficients.

Learn, Assign, and Search: Real-Time Estimation of Dynamic Origin-Destination Flows Using Machine Learning Algorithms

open access: yesIEEE Access, 2019
A common way to estimate dynamic origin-destination (O-D) flows is to establish and solve a bilevel optimization model. Though numerous efforts have been devoted to effectively and efficiently solving the model, challenges still exist because of the ...

Dynamic Flow Analysis for JavaScript [PDF]

open access: yes, 2019
Static flow analyses compute a safe approximation of a program’s dataflow without executing it. Dynamic flow analyses compute a similar safe approximation by running the program on test data such that it achieves sufficient coverage.We design and implement a dynamic flow analysis for JavaScript.

Immigration Trends After 20 Years of NAFTA

open access: yesNorteamérica, 2014
The twentieth anniversary of nafta is an opportunity to reflect on what has happened to migration flows. In this essay, the author gives an overview of the trends of Mexican legal high- and low-skilled migration flows as well as of unauthorized flows to ...

Foundations of Engineering Mathematics Applied for Fluid Flows

open access: yesAxioms, 2021
Based on a brief historical excursion, a list of principles is formulated which substantiates the choice of axioms and methods for studying nature. The axiomatics of fluid flows are based on conservation laws in the frames of engineering mathematics and ...

On the Unsteady, Dynamic Response of Phase Changes in Hydraulic Systems [PDF]

open access: yes, 1979
This paper is concerned with the unsteady, dynamic behavior of hydraulic systems and, in particular, with the dynamic characteristics of internal flows involving phase-change and two-phase flows.

Biophilic urban developments following dynamic flows of tree-shaped architectures [PDF]

open access: yes, 2015
Latest theories and practices in Biophilic designs of the urban space regard the urban fabric as being composed of several interrelated layers of energetic structure influencing each other in a non-linear manner primarily.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
