Which of the following equations is correct? A. resistivity of X × length of X = resistivity of Y × length of Y B. length of cross sectional area of length of cross sect X X Y = i onal area of Y C. resistivity of cross sectional area of resistivity of X X ×= cross sectional...
Summary: Many problems in introductory Physics require the student to enter a system of algebraic equations as the answer. Tutoring systems must be able to understand the student's submission before they can generate useful feedback. This paper presents an approach that accepts from the student a...
In this paper, we focus specifically on equality-type constraints with the objective of minimizing the sum of squared residuals (SSR), and thus it is possible to use the well-known method of Lagrange multipliers. The Karush-Kuhn-Tucker (KKT) stationarity condition yields a system of equations ...
Physics-informed neural networks (PINNs) have enabled significant improvements in modelling physical processes described by partial differential equations (PDEs) and are in principle capable of modeling a large variety of differential equations. PINNs are based on simple architectures, and learn the behavi...
Harnessing data to discover the underlying governing laws or equations that describe the behavior of complex physical systems can significantly advance our modeling, simulation and understanding of such systems in various science and engineering discipli

Give separate numbering to formulae and equations within appendices using formats such as Eq. (A.1), Eq. (A.2), etc. and in subsequent appendices, Eq. (B.1), Eq. (B. 2) etc. In a similar way, give separate numbering to tables and figures using formats such as Table A.1; Fig...
The primary focus of this paper is to address this issue. Recent studies have revealed the deep-rooted relationship between neural network structures and ordinal/partial differential equations (ODEs/PDEs)44,45,46,47,48,49. For example, Lu et al.45 bridged deep convolutional network architectures...
By using Mathematica to solve these equations, we can get the values of the unknowns \(p _i, q_ i\), m, and c, which will be utilized to obtain the answer to Eq. (3). The extended simple equation method We suppose the trial solution of the partial differential equation (PDE) of...
