Ice sheet surface mass balance describes the net snow accumulation at the ice sheet surface.On the Antarctic ice sheet, winds redistribute snow, resulting in a surface mass balance that is variable in both space and time.Representing wind-driven snow redistribution processes in models is critical for local assessments of surface mass balance, repea
Introduction & Objective: Diagnosis of periodontal osseous lesions is very important in deter-mining prognosis, treatment plan and maintenance in the long term.This diagnosis can be achieved by using radiography.The aim of this study is to compare accuracy of E speed films, bitewing PSP, panoramic PSP and CCD for identifying the extent of destructi
This paper is primarily focused on the robust control of an inverted pendulum system based on policy iteration in reinforcement learning.First, a mathematical model of the single inverted pendulum system is established through a force analysis of the pendulum and Cast Iron SMAW trolley.Second, based on the theory of robust optimal control, the robu
Aiming at the characteristics of various types of equipment in coal preparation plant and the dispersion of monitoring points,a multi-source information wireless transmission and classification algorithm for equipment based on compressed sensing was proposed.By constructing a multi-hop information transmission model,the information transmission pro
