For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Abstract: Matrix approximation methods have successfully produced efficient, low-complexity approximate transforms for the discrete cosine transforms and the discrete Fourier transforms. For the DFT ...

The method seems to provide much closer accuracy to the slow method, while maintaining the same time complexity (just scaled up by a constant). I suggest we parallellize the FFTs in the LRA optionally ...

In this tutorial, we will solve one of the exercises proposed in a previous issue. The solution lends itself to an interesting interpretation of the famous Gibbs-Wilbraham phenomenon. In this tutorial ...

ABSTRACT: In the author’s recent publications, a parametric system biorthogonal to the corresponding segment of the exponential Fourier system was unusually effective. On its basis, it was discovered ...

ABSTRACT: This paper covers the concept of Fourier series and its application for a periodic signal. A periodic signal is a signal that repeats its pattern over time at regular intervals. The idea ...

Abstract: Hybrid interferences of dynamic dc interferences and ac interferences could cause stronger direct corrosion effects to pipelines than either type alone posing greater potential safety ...

The man gazes straight ahead, his eyes as dark as coals. His nose juts prominently from his tan face, which has become creased with wrinkles over time. Tufts of gray hair sprout from his balding head.
