We present a general method for solving the modified Helmholtz equation without shape approximation for an arbitrary periodic charge distribution, whose solution is known as the Yukawa potential or ...

The mathematical expressions of surrogate model for the flexoelectric materials are established by considering uncertain parameters such as independent Young’s modulus, concentrated load and ...

The article written by Percy E. Ludgate in 1909 first gives thanks to Professor C. V. Boys, F.R.S. for his assistance on the subject of analytical machines. Ludgate also refers to the work of Charles ...
