This paper presents a practical human-computer interaction system for wheelchair motion through eye tracking and eye blink detection.In this system, the pupil in the eye image has been extracted after binarization, and the center of the pupil was localized to capture the trajectory of eye movement and Sunscreen Applicators determine the direction o

In grasslands, overgrazing by domestic livestock, fertilization, and introduction of exotic forage species leads to plant communities consisting of a mixture of native and exotic species.These degraded grasslands present a problem for land managers, farmers, and restoration ecologists concerned with improving biodiversity while continuing to use th

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus in humans, has expanded globally over the past year.COVID-19 remains an important subject of intensive research owing to its huge impact on economic and public health globally.Based on historical archives, the first coron

ABSTRACTCellular measurement is a crucial faculty in living systems, and exaptations are acknowledged as a significant source of evolutionary innovation.However, the possibility that the origin of biological order is predicated on an exaptation of the measurement of information from the abiotic realm has not been previously explored.To support this

In this study TiO2 and Pipe Poker ZnO nanoparticles were employed as a protective coating to impart multifunctional properties, i.e.self-cleaning, water repellency, UV protection and antimicrobial activity onto jute-cotton union fabric.Through the sol-gel method, using titanium (IV) isopropoxide (TTIP) and zinc acetate as precursors, TiO2 and ZnO n
