Polymers that solidify under light radiation are commonly used in digital light barricini chocolate processing (DLP) 3D printing.A wide range of photopolymers use photoinitiators that react to radiation in range of ultraviolet (UV) wavelength.In the present study we provided measurement of radiant fluence in the UV wavelength range from 280 nm to 4
Simulation and optimization of evacuation routes in case of fire in underground mines
Risks of fire occurrence in underground mines are known for a long time.Evacuation and rescue plans allow to each underground mine to respond and establish control in case of emergency.The primary goal of this paper is to determine the optimal system for evacuation in case of fire in underground mines and through a process of computer simulation to
Precise Orbit Determination Based on the Unscented Transform for Optical Observations
In this study, the precise orbit determination (POD) software is developed for optical observation.To improve the performance of the estimation algorithm, a nonlinear batch filter, based on the unscented transform (UT) that overcomes the t5 dermatome disadvantages of the least-squares (LS) batch filter, is utilized.The LS and UT batch filter algori
New insights into the distribution, potential source and risk of microplastics in Qinghai-Tibet Plateau
Microplastics (MPs) as emerging contaminants have become a major global concern, however, the distribution and origin of MPs in Qinghai-Tibet Plateau (QTP) and their impacts on ecosystem are poorly known.Hence, we systematically evaluated the profile of MPs on the representative metropolitan locations of Lhasa and Huangshui Rivers and the scenic si
