THE SPECTRAL SENSIBILITY OFA VENA By CHARLES HAIG

Bilateral Pulmonary Artery, Inferior Vena Cava, and Cardiac Echinococcosis: A Rare Presentation of Zoonotic Diseases

Introduction:Cystic hydatidosis is a zoonoticdisease thatis mostly observedin the Mediterranean region. This infectious disease may present throughdifferent manifestations that may delay the diagnosis and cause various complications for the patients. Most of the cases are usually diagnosed by imaging studies and the related management could be medical or surgical depending on the patient’s clin...

The Visual Functions of the Complete Colorblind

1. The visual functions of a completely colorblind individual are compared with those of the normal. The sensibility distribution in the spectrum has a maximum at 520 mmicro at all brightnesses and thus corresponds to rod vision alone. This is confirmed by studies of dark adaptation which show final thresholds like those usually found for rod vision. Dark adaptation, measured both centrally and...

The Dark Adaptation of Retinal Fields of Different Size and Location

The decrease in threshold shown by the eye during dark adaptation proceeds in two steps. The first is rapid, short in duration, and small in extent. The second is slow, prolonged, and large. The first is probably due to cone function; the second to rod function. In centrally located fields the two parts of adaptation change differently with area. With small, foveal fields the first part dominat...

In recent years, the spectral analysis has been one of the most important research areas in remote sensing, which has received different traditional solutions. Most of these methods have several special conditions to work well. However, they suffer from the problems such as sticking in local optimum and having sensibility to parameters initialization. Although the Evolutionary Computation (EC) ...
