EVALUATION OF COLOUR VISION DEFECTS USING D-15 IN RELATION WITH IRIS COLOUR AND PUPIL SIZE; A CROSS-SECTIONAL STUDY

open access: yesRehman Journal of Health Sciences
Introduction: Colour of iris is associated with race and may show hereditary patterns. In this context it may be associated with colour vision defects and size of pupil.

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

open access: yesAdvanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Tritanopia and Colour Vision [PDF]

open access: yesNature, 1946
THE existence of foveal tritanopia, in spite of the convincing observations of d'Alrutz (1909), Richardson-Robinson (1923) and Gothlin (1943), has been denied by those who, like Polack1, disagree with the trichromatic theory of colour vision and the classical division of dyschromatopsies.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

A Clinical Study of Colour Vision Status of Female Relatives of Indian Males with Defective Colour Vision [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Introduction: Around 15% of females are carriers of congenital colour blindness. Variable colour vision status exists in these heterozygous carrier females due to various factors such as retinal mosaicism and the likelihood of the presence of an ...

High-fidelity colour reproduction for high-dynamic-range imaging [PDF]

open access: yes, 2010
The aim of this thesis is to develop a colour reproduction system for high-dynamic-range (HDR) imaging. Classical colour reproduction systems fail to reproduce HDR images because current characterisation methods and colour appearance models fail to ...

Inherited colour vision deficiencies: From Dalton to molecular genetics [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2005
In recent years, great advances have been made in our understanding of the molecular basis of colour vision defects, as well as of the patterns of genetic variation in individuals with normal colour vision.

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

A potential new colour vision assessment tool for young children

open access: yesBritish and Irish Orthoptic Journal, 2012
Aim:  There are many colour vision tests available that detect, classify and grade colour deficiency for adults. Testing colour vision in older children is possible using the same tests but very young children may not yet be confident in identifying ...
