Compact Linear Flow Phantom Model for Retinal Blood-Flow Evaluation [PDF]

open access: yesDiagnostics
Impaired retinal blood flow is associated with ocular diseases such as glaucoma, macular degeneration, and diabetic retinopathy. Among several ocular imaging techniques developed to measure retinal blood flow both invasively and non-invasively, adaptive ...

Linear flows on compact, semisimple Lie groups: stability and periodic orbits

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
Our first purpose is to study the stability of linear flows on real, connected, compact, semisimple Lie groups. Our second purpose is to study periodic orbits of linear and invariant flows.

Branching in flow networks with linear congestion

open access: yesPhysical Review Research, 2022
In our modern world, we rely on the proper functioning of a variety of networks with complex dynamics. Many of them are prone to congestion due to high loads, which determines their operation and resilience to failures.

Probabilistic data flow analysis: a linear equational approach [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
Speculative optimisation relies on the estimation of the probabilities that certain properties of the control flow are fulfilled. Concrete or estimated branch probabilities can be used for searching and constructing advantageous speculative and ...

Micro-volume couette flow sample orientation for absorbance and fluorescence linear dichroism [PDF]

open access: yes, 2004
Linear dichroism (LD) can be used to study the alignment of absorbing chromophores within long molecules. In particular, Couette flow LD has been used to good effect in probing ligand binding to DNA and to fibrous proteins.

An approximation of behind-casing hydraulic conductivity between layers from transient pressure analysis

open access: yesDyna, 2019
Flow behind the casing has normally been identified and quantified using production logging tools. Very few applications of pressure transient analysis, which is much cheaper, have been devoted to determining compromised cemented zones.

Analysis of pressure and pressure derivative interference tests under linear and spherical flow conditions

open access: yesDyna, 2018
Often, interpretation of interference tests is performed for systems acting under radial flow regimen conditions by means of conventional straight-line method, type-curve matching and TDS technique. For linear and spherical flow cases, the interpretation

Adaptive linear solution process for single-phase Darcy flow

open access: yesOil & Gas Science and Technology, 2020
This article presents an adaptive approach for solving linear systems arising from self-adjoint Partial Differential Equations (PDE) problems discretized by cell-centered finite volume method and stemming from single-phase flow simulations. This approach

Impact of Permanent Magnet Field on Inductance Variation of a PMLSM [PDF]

open access: yes, 2007
Analytical models of Surface Mounted Permanent Magnet Linear Synchronous Motors are generally presented with constant inductances. However, the impact of powerful rare-earth PMs in the saturation phenomena cannot be neglected anymore.
