5.6.4 Error estimates The errors made on the computation of the sound field are first caused by the use of the parabolic approximation. In [14], F. Tappert gives for a simple case a comparison between an exact solution and the solution of the parabolic equation. The errors are also cause...

There is still a relatively serious disease burden of infectious diseases and the warning time for different infectious diseases before implementation of interventions is important. The logistic differential equation models can be used for predicting early warning of infectious diseases. The aim of this ...
one of China’s most popular online platforms for synchronous learning. This study aimed to extend the Unified Theory of Acceptance and Use of Technology (UTAUT) by incorporating new constructs and examining the factors that affect users’ behavioral intention and use behavior of DingTalk. The study...
I am running into an error when I try to perform a weighted poly 1 fit. The weights I am using are the inverse of the errors on the data points squared (1/error^2). The commands I am using are: options=fitoptions('Weights',1/(toterr(good)).^...
► Developed a new parametric wind pressure coefficient equation for low-rise buildings from a curve fit to the analyzed database. ► New equation is a rational function of wind angle and building side ratio. Introduction Wind is a structural load on buildings and so it is very important ...
I will be using unstructured FrameMaker 15.0.6.956 for the project below. I am working on a document in Word that I will be moving to FrameMaker a little later in the process. (The original doc is in Word and there are multiple writers who are still working in the Word version using...
Results show that the GP can predict the solution of the seismic wave equation with a lower level of error, while our developed neural network is more accurate for velocity (P- and S-wave) and density inversion. Keywords: Gaussian process (GP), Physics informed machine learning (PIML) ,...
