A geometric model of multi-scale orientation preference maps via Gabor functions

open access: yes, 2017
In this paper we present a new model for the generation of orientation preference maps in the primary visual cortex (V1), considering both orientation and scale features. First we undertake to model the functional architecture of V1 by interpreting it as

A Finite Element Model for Describing the Effect of Muscle Shortening on Surface EMG [PDF]

open access: yes, 2006
A finite-element model for the generation of single fiber action potentials in a muscle undergoing various degrees of fiber shortening is developed. The muscle is assumed fusiform with muscle fibers following a curvilinear path described by a Gaussian ...

Fast Fiber Orientation Estimation in Diffusion MRI from kq-Space Sampling and Anatomical Priors

open access: yes, 2018
High spatio-angular resolution diffusion MRI (dMRI) has been shown to provide accurate identification of complex fiber configurations, albeit at the cost of long acquisition times.

THE INFLUENCE OF FIBER ORIENTATION ON ENGINEERING CONSTANTS OF LAMINATED COMPOSITES [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists), 2015
A laminated composite is generally formed by stacking unidirectional laminas, with different fiber orientation angles, in the direction of the laminate thickness, in order to satisfy the design requirements.

Fibers Effects on Contract Turbulence Using a Coupling Euler Model

open access: yesApplied Sciences, 2021
Fiber additive will induce the rheological behavior of suspension, resulting in variation in velocity profile and fiber orientation especially for the non-dilute case.

Deformation of a flexible fiber in a viscous flow past an obstacle [PDF]

open access: yes, 2015
We study the deformation and transport of elastic fibers in a viscous Hele-Shaw flow with curved streamlines. The variations of the global velocity and orientation of the fiber follow closely those of the local flow velocity. The ratios of the curvatures

Algorithm for fast evaluation of in-plane fiber orientation in reinforced plastics using light microscopy images

open access: yesCommunications Materials, 2023
Methods for evaluating the orientation of carbon fibers in reinforced plastics vary in complexity and are application specific. Here, we report an algorithm that quickly evaluates in-plane fiber orientation based on determining the correlation ...

Fiber Orientation as a Means to Control Formation on the Ultra-Former Through Changes in the Spouting Jet to Wire Speed Ratio and Stock Consistency in the Headbox [PDF]

open access: yes, 1972
The Ultra-Former is a new type of multi-ply board machine. It uses a cylinder mold without a vat and has a stock delivery system that uses a headbox similar to that found on a fourdrinier machine.

Factors Influencing Reinforcement of NR and EPDM Rubbers with Short Aramid Fibers [PDF]

open access: yes, 2010
Among short fiber reinforced composites, those with rubbery matrices have gained great importance due to the advantages they have in processing and low cost, coupled with high strength.
