In contrast to cumbersome benchtop spectrometers, integrated on-chip spectrometers are well-suited for portable applications in health monitoring and environmental sensing.In this paper, we have developed an on-chip spectrometer with a programmable silicon photonic filter by simply using parallel cascaded micro-ring resonators (MRs).By altering the
For years great interest has been taken in the effects of physical phenomena on ionosphere structure.A total solar eclipse was visible in North America on August 21st, 2017.This event offered a great opportunity for remote sensing the ionospheric behavior under the eclipse condition.In this study we investigated the effects of total solar eclipse o
This paper presents an input shaping control system for overhead crane operations involving simultaneous hoist and travel maneuvers.The cashel tail bag control system utilizes model-based partial feedback linearization with frequency modulation.Traditional input shaping controllers target specific system frequencies.Therefore, they are incapable of
Phosphorus (P) chemistry and its dynamic cycling are essential for understanding aquatic here primary productivity and ecosystem structure.However, there is a lack of knowledge on P chemistry in pristine aquatic ecosystems, such as in Antarctica.Here, we applied the Standards, Measurements and Testing Program (SMT) procedure and nuclear magnetic re
