A reflection-based fibre-optic refractive index sensor using surface plasmon resonance (SPR) in a thin Sushi Boat metal film sputtered on a bare core of a multimode optical fibre is presented.The sensing element of the SPR fibre-optic sensor is the core of a step-index optical fibre made of fused silica with a gold film double-sided sputtered on th
Objective: The conventional management of rhino-orbito-cerebral (ROC) mucormycosis includes control of metabolic abnormality, administration of amphotericin B and surgery that spans simple sinus clearance, radical debridement and orbital exenteration.Recent literature includes anecdotal descriptions of successful treatment with conservative managem
With the aid of disturbance observer strategy, this article aims to investigate the disturbance rejection and stabilization problems for periodic piecewise time-varying systems that are subject to time-varying delays, parameter uncertainties, nonlinear perturbations and exogenous disturbances.To be more specific, the periodic piecewise time-varying
IoT enables the emergence and implementation of smart devices to address real-world problems and challenges.Today we are surrounded by various smart devices, such as smart phones, smart homes, smart cars, smart televisions, and smartwatches that assist us in making our lives easier and smoother.IoT is a conglomeration of multiple technologies at va
Abstract The digital transformation of education has rapidly evolved in recent years, driven wand-massagers by advancements in technology and further accelerated by the COVID-19 pandemic.Digital education Technologies (DETs) have become integral to higher education, reshaping how institutions deliver learning and manage resources.However, despite t
