To solve the failure problem of the visible/near infrared (VIS/NIR) spectroscopy model, soluble solids content (SSC) detection for fresh jujubes cultivated in different modes was carried out based on the method of variable optimization and model update.Iteratively retained informative variables (IRIV) and successive projections algorithm (SPA) algo
Fluorocarbon surfactants could change coal structure and improve wettability characteristics, thus, it plays a significant role in coal dust prevention and control.Composite dust suppressant based on fluorocarbon surfactant (FS-31) enhancement was developed, and the surface tension and contact angle characteristics were analyzed.Based on the infrar
The paper presents a numerical assessment of various room heating methods using assembled room models.It compares the efficiency of floor heating, ceiling heating, and plane radiator heating in a selected room of a family house under winter conditions in the Central European climate zone.COMSOL Multiphysics software is used for computer simulations
This Bee Products study focuses on the analysis of the existing design solution of shedding mechanism.It is characterised by a heald attachment into the heald shaft with a necessary design allowance.The preparation of a mathematical model for the new concept of the heald attaching to the heald shaft frame is explained in this study.A damping elemen
