January is Radon Action Month, and the Cook County Department of Public Health is urging residents to test their homes for radon. The colorless, odorless, radioactive gas is the second leading cause ...

Radon is a toxic, odorless gas that can enter any home with ground contact. A radon mitigation system can remove dangerous levels of the gas from a home's air. Radon exposure is the leading cause of ...

A Dispatch investigation found many Ohioans are unaware of the dangers of radon, a leading cause of lung cancer in nonsmokers. Ohio has no laws requiring radon testing in schools or daycares, unlike ...

Here’s a draft of my next column for the Notices of the American Mathematical Society. It’s about the inverse cube force law in classical mechanics. Newton’s Principia is famous for his investigations ...

An alternative method to invert the Radon transforms without the use of Courant–Hilbert’s identities has been proposed and developed independently from the space dimension. For the universal ...

This project demonstrates the application of Radon transform and its inverse for line filtering in images. The implementation uses a Gaussian padding technique to enhance specific angular components ...

In part 3 of this series, we used the inverse fast Fourier transform (IFFT) to create 100-Hz time-domain waveforms of various amplitudes and phases. We can also use the IFFT to create waveforms ...

The inverse transform can create a time-domain waveform where no waveform has been before. In part 2 of this series, we used the discrete Fourier transform to convert a waveform from the time domain ...
