An incompressible unsteady free convective viscous MHD rotating flow past a moving plate embedded in a porous medium is considered with the influence of viscous dissipation, heat source effects. It is assumed that the flow rotates with angular velocity which is normal to the plate and also that a transverse magnetic field is applied along the normal to the plate. Appropriate dimensionless quantities...
The demonstrated variable efficacy of the only licensed TB vaccine Mycobacterium bovis bacillus Calmette–Guérin (M. bovis BCG) encourages the need for new vaccine candidates against TB. Antigen specific cellular immune response is often considered imperative during Mycobacterium tuberculosis (M. tuberculosis) infection and antigens that are strongly associated with the latent phase of infection are...
Diabetic retinopathy (DR) is a chronic disease which causes visual impairment in industrialized countries. Automatic detection of DR early markers can contribute to the diagnosis and screening of the disease. The aim is to automatically detect early signs of red lesions. So the need arises for fast and efficient system which detect whether the patient is suffering from diabetic retinopathy or not...
Blood vessel segmentation can be used for automatic retinal disease screening system. In this paper, comparison of automatic blood vessel segmentation methods in retinal images is presented and discussed. Morphological operation for the automatic segmentation of blood vessels in retinal images has been proposed and the results are compared with matched filter technique using local entropy thresholding...
The localization of Optic Disc (OD) is an initial step for the segmentation of various pathological features like microaneurysms, hemorrhages, exudates etc. We propose a new technique for the localization of OD boundary in retinal images. The retinal image consists of blood vessels that emerge from the OD. The presence of these blood vessels may act as a disturbance for the localization of OD. Cumulative...
This paper proposes a method to automatically locate the optic disc in a retinal image. Our method of finding the optic disc is based on the properties of the optic disc using simple image processing algorithms which include multilevel thresholding, Morphological process detection of object roundness and circle detection by circle fitting method. The proposed method is able to recognize the retinal...
