The Numerical Algorithms Group (NAG), a world leader in high quality computational software and high performance computing services to tens of thousands of users in major academies, Global 500 ...

The IMEX schemes apply the implicit temporal method to only a small portion of the domain and use explicit calculations elsewhere, based on a convenient splitting algorithm. IMEX methods effectively ...

Spectral methods are very efficient numerical algorithms for solving partial differential equations in relatively simple geometries. The numerical errors introduced by spectral algorithms typically ...

Global warming has put a significant strain on resources, and hence, economic opportunities, military considerations, and trade. The development of Arctic shipping routes is necessary to compensate ...

This application note presents a numerical algorithm for IGBTs that operate in switch mode power circuits in order to determine its losses. The design example uses a 600 W zero-current switching boost ...
