Background: Fungal corneal ulcer is the most dangerous and challenging type of infective keratitis.  Since most of the ophthalmic antifungal drops are scarce and expensive in developing countries, attempts have been made to study fungicidal property of some readily available antiseptic agents as a substitute.  Povidone iodine (PI) and chlorhexidine gluconate (CHx) has been postulated to be effe...

The preservation of the semi-martingale property in a progressive enlargement of filtration has been studied by many authors. Most of them focus on progressive enlargement with a honest time, allowing for semi-martingale invariance and simple decomposition formulas. However, times allowing for semi-martingale invariance in initial enlargements preserve as well this property in progressive enlar...

When the parameter of any systems changes with respect to time then the constant gain PI controller action is not effective. In case of MRAC based design the adjustable PI gain parameters corresponding to changes in plant will be determined by referring to reference model specifying the property of desired control system. This paper presents the method to design MRAC based PI controllerfor spee...

Optoelectronic properties of hematite (α-Fe2O3) as a photoanode and the required over-potential in photo-assisted water splitting has been improved by presence of Co-Pi on its surface. In order to increase the lifetime of the photogenerated holes and lower the applied bias, cobalt-phosphate (Co-Pi) on nanostructured α-Fe2O3 by electrodeposition was de...

In this paper, a nonlinear extension of the Georgiou-Smith system is considered and robustness results are proved for a nonlinear PI controller with respect to fast parasitic first-order dynamics. More specifically, for a perturbed nonlinear system with sector bounded nonlinearity and unknown control direction, sufficient conditions for global boundedness and attractivity have been derived. It ...
