The coronavirus pandemic that broke out in 2019 has finally calmed down in China, after the bungling occasioned by the iron hand of lockdown. But beginning in March 2020, the disaster spread abroad, and at present there is no end in sight. In this work, Qin Hui offers a bracing examination of the impact of coronavirus pandemic on political institutions in both China and the West. Deliberating on the contradiction between "human rights" and "human survival," he contends that China has achieved success in imposing coercive lockdowns to control the virus, but it will be a challenge to prevent the normalization of emergency measures from worsening human right conditions. The West, in contrast, must learn how democracies can efficiently enter a state of emergency and put an end to these measures at the proper time.

Although the Trefftz finite element method (FEM) has become a powerful computational tool in the analysis of plane elasticity, thin and thick plate bending, Poisson's equation, heat conduction, and piezoelectric materials, there are few books that offer a comprehensive computer programming treatment of the subject. Collecting results scattered in the literature, MATLAB(R) and C Programming for Trefftz Finite Element Methods provides the detailed MATLAB(R) and C programming processes in applications of the Trefftz FEM to potential and elastic problems.

The book begins with an introduction to the hybrid-Trefftz (HT) FEM that covers basic concepts and general element formulations of the method. It then concentrates on both the essentials and subroutines of MATLAB and C programming. The next few chapters present applications of T-elements to potential problems and linear plane elasticity, discuss how to solve body force in elasticity through radial basis functions, and examine how special purpose functions can be constructed. The final chapter explores advanced topics, such as the construction of Trefftz "p"-elements, dimensionless transformation, and an alternative formulation to HT FEM.

Unifying the computer programming aspects of the Trefftz FEM, this book will stimulate the development and application of this novel method in many facets of practical engineering.
