Glaucoma and Diabetic Retinopathy are the leading common cause of vision loss. Optic Disc and macula are the important landmark for the detection of these retinal pathology. Even though, the manual screening of Optic Disc and macula are available, they consume more time and have more human error. Therefore, there is a need of an automated application for the reliable and efficient localization of...
Diabetic Retinopathy (DR) is the primary cause of visual loss in case of diabetic patients. It is mainly caused by the changes in the blood vessels of the retina even though manual screening is available but they are very much time consuming and inefficient. Therefore for automatic detection of these changes and prevention of vision loss, color retinal image is an important tool used by the ophthalmologist...
Even though a number of anatomical structures contribute to the process of vision, many eye disease that causes blindness occur mainly in the retina. One among the important eye disease is Diabetic Retinopathy. DR is a severe eye disease and is the primary cause of blindness in the case of diabetic patients. We describe a novel method for automatically detecting the exudates with the help of retinal...
Diabetic Retinopathy is the major cause of blindness in many diabetic patients. Automatic detection of exudates in retinal images can assist in early screening of Diabetic Retinopathy. Several techniques can achieve good performance on a good quality retinal images. But when the image is of low quality, we need a new method. In this paper, we presented a novel method for the detection of exudates...
The efficiency of electric distribution can be improved by using the technique called "distribution automation (DA). "In this paper, the problems of the current distribution system are discussed. Then the technique of distribution automation is described briefly along with an application of artificial Intelligence (AT) methods and e-services in electric distribution systems.
We compare energy relaxation in 1-D tunnel field-effect transistors (FETs) vs. thermionic FETs, focusing on carbon nanotubes (CNTs). In CNTs the strongest inelastic scattering process with optical phonons has very high energy, n??OP ?? 0.18 eV, three times higher than in Si. We find the energy relaxation rate in tunnel FETs is up to 20 times slower than in thermionic FETs for ~1000 ??A/??m current...
Analog four-quadrant multipliers suffer from errors in the output owing to various factors including process, temperature and bias conditions. In most cases, little can be done to avoid these errors. This paper introduces a new analog four quadrant multiplier that employs the weighted summing capability of the Floating Gate MOSFET (FGMOS). The circuit features a wide input range that exceeds the power...
