Low complexity symbol detection method for multilevel 2-D optical storage based on a linear channel model [PDF]

open access: yes, 2005
A symbol detection scheme based on the Viterbi algorithm that simultaneously processes subsets of 2-D data in the presence of Gaussian noise was recently proposed for binary 2-D optical storage (TwoDOS).

Drive-noise tolerant optical switching inspired by composite pulses [PDF]

open access: yes, 2020
Electro-optic modulators within Mach--Zehnder interferometers are a common construction for optical switches in integrated photonics. A challenge faced when operating at high switching speeds is that noise from the electronic drive signals will effect ...

Accurate and reliable segmentation of the optic disc in digital fundus images [PDF]

open access: yes, 2014
We describe a complete pipeline for the detection and accurate automatic segmentation of the optic disc in digital fundus images. This procedure provides separation of vascular information and accurate inpainting of vessel-removed images, symmetry-based ...

An investigation into the fertilizer particle dynamics off-the-disc [PDF]

open access: yes, 2015
The particle size range specifications for two biosolids-derived organomineral fertilizers (OMF) known as OMF10 (10:4:4) and OMF15 (15:4:4) were established.

Computational simulation of the intervertebral disc [PDF]

open access: yes, 2013
The intervertebral disc is a complex structure unlike any other in the human body. The capability to withstand high loads and deformations in six degrees of freedom is facilitated by the unique soft tissue structures. However, the mechanical behaviour of

Mean curvature and texture constrained composite weighted random walk algorithm for optic disc segmentation towards glaucoma screening

open access: yesHealthcare Technology Letters, 2018
Accurate optic disc (OD) segmentation is an important step in obtaining cup-to-disc ratio-based glaucoma screening using fundus imaging. It is a challenging task because of the subtle OD boundary, blood vessel occlusion and intensity inhomogeneity.
