Retinopathy in newly presenting non-insulin-dependent (type 2) diabetic patients.
One hundred and twenty-nine (97 M, 32 F) previously untreated non-insulin-dependent diabetic patients were studied. Meal and glucose (75 g) tolerance tests were performed on two separate days with… Expand

A multilayer feedforward network has been developed for the classification of diabetic retinopathy and its robustness in noisy environments. Expand
Some Relationships among Vieta, Morgan-Voyce and Jacobsthal Polynomials
We define below the Morgan-Voyce polynomials B n(x) and b n(x) , and the ‘companion’ Morgan-Voyce polynomials C n(x) and c n(x) which were found in embryonic form in  and formalized,… Expand
Divisibility properties of some fibonacci-type sequences
A generalized Fibonacci-type sequence is defined from a fourth order homogeneous linear recurrence relation, and various divisibility properties are developed. In particular, the notion of a proper… Expand
Some problems in the mathematical modelling of erythrocyte sedimentation.
The rate at which red blood cells fall in vitro is used as a common clinical test, amongst others, for a number of pathological conditions. The use of this test is cast into doubt when one finds… Expand
Modelling of a Roulette Wheel Selection Operator in Genetic Algorithms Using Generalized Nets
The apparatus of Generalized Nets (GN) is applied here to a description of a selection operator, which is one of the basic genetic algorithm operators. The GN model presented here describes roulette… Expand
CLASSIFICATION OF DIABETIC RETINOPATHY LESIONS FROM
