The Meaning of Silence for Mastering the Practitioner’s Reflective Skills
Multidisciplinary Journal of School Education, 2021 The aim of the article is to show the meaning of practicing silence, enhancing the quality of the reflective skills of the reflective practitioner. These skills – being, speaking, disclosing, testing, and probing – reveal one’s reflective competences ...

Suppression Method of Optical Noises in Resonator-Integrated Optic Gyroscopes
Sensors, 2022 Resonator-integrated optical gyroscopes have advantages such as all-solid-state, on-chip integration, miniaturized structure, and high precision. However, many factors deteriorate the performance and push it far from the shot-noise limited theoretical ...

Noise analysis of reflection‐type microwave RTD amplifier [PDF]
IET Circuits, Devices & Systems, 2020 This study reports an analysis of noise figures (NFs) in a reflection‐type microwave amplifier using resonant tunnelling diodes (RTDs). The minimum NF for the RTD amplifier based on 0.9 μm InP process technology, featuring a power gain ( S 21 ) of 10.4 dB and a dc‐power ...

Comparison and Noise Suppression of the Transmitted and Reflected Photoplethysmography Signals [PDF]
BioMed Research International, 2018 The photoplethysmography (PPG) is inevitably corrupted by many kinds of noise no matter whether its acquisition mode is transmittance or reflectance. To enhance the quality of PPG signals, many studies have made great progress in PPG denoising by adding extra sensors and developing complex algorithms.

On-Orbit Noise Characterization for MODIS Reflective Solar Bands [PDF]
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008 MODIS collects data in 36 spectral bands, with wavelengths from 0.41 to 14.4 mum, and at three nadir spatial resolutions: 0.25 km, 0.5 km, and 1 km. MODIS reflective solar bands (RSB) on-orbit calibration is performed using an on-board solar diffuser (SD) and a solar diffuser stability monitor (SDSM).

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
