A method is proposed for calculating main aerodynamic characteristics of the main Foggers rotor of the Mi-26 helicopter: a lift, a reactive moment, a required power of the propulsion system, a speed of the inductive air flow, a throttle response coefficient, a speed of the horizontal flight.This method based on the pressure propeller theory.The par
We investigated the impact of surface treatments on Si-based electrolyte-gated transistors (EGTs) for detecting urea.Three types of EGTs were fabricated with distinct gate electrodes (Ag, Au, Pt) using a top-down method.These EGTs exhibited exceptional intrinsic electrical properties, including a low subthreshold swing of 80 mV/dec, a high on/off c
Abstract Generally, sunflower seeds are classified by machine vision-based methods in production, which include using photoelectric sensors to identify light-sensitive signals through traditional algorithms for which the equipment cost is relatively high and using neural network image recognition methods to identify images through cameras for which
Purpose The purpose of this study was to evaluate the incidence rate and trend of bladder cancer in South Korea using a nationwide database.In addition, we aimed Point to determine the risk factors and their influence on the incidence of bladder cancer.Materials and Methods We extracted data from the health insurance database and estimated the inci
