Gaussian-Fitting-Enabled High-Accuracy pH Detection for Light-Addressable Potentiometric Sensor [PDF]
SensorsA light-addressable potentiometric sensor (LAPS) is a low-cost and versatile semiconductor field-effect pH sensor. In practical application, typical pH detection based on LAPS usually adopts the method of normalizing the voltage–photocurrent (V-I ...

Estimation of Polar Depletion Regions by VTEC Contrast and Watershed Enhancing [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2022 This article presents a method for determining near-Pole ionization depletion regions and troughs from global navigation satellite system (GNSS) vertical total electron content (VTEC) maps. To define the regions, we use Image processing tools, considering the VTEC maps as gray-level images.
