Let's delve into the multifaceted nature of the function z = e^x cos(y). This function, seemingly simple at first glance, unveils a rich tapestry of mathematical concepts and visualizations when ...

Abstract: In this paper, a novel digital image watermarking scheme has been proposed based on spread spectrum technique. By exploiting complex exponential function to generate a multiple-rings shaped ...

31 March 2026. Project is open to Home applicants only. The solutions of a polynomial equation have an algebraic structure, a Galois group, which gives the symmetry group of the solutions under field ...

Indexing is bottleneck for transforms. Switching to standard representation for FFT will resolve this. Right now the basis functions for the Fourier series are single-variable trigonometric functions, ...

Oscilloscopes are the workhorse instruments for time domain measurements. Most current digital oscilloscopes include about twenty-five built in measurement parameters as a standard complement. Adding ...
