A pressure therapy method: Monaural beats sonic resonance

May 24, 2024 by Tsen-Fang Lin, Liang-Bi Chen

< This article introduces a non-invasive pressure therapy method using monaural beats (MB) sonic resonance to promote relaxation and reduce stress. Unlike binaural beats (BB), MB requires no headphones, enhancing accessibility. By targeting ultralow brainwave frequencies, MB effectively relieves anxiety and stress. Compared to BB and other infrasound methods, MB … [Read more...] about A pressure therapy method: Monaural beats sonic resonance

Narrowband and wideband frequency modulation spectral characterization and bandwidth calculation

March 2, 2023 by Ahmed M. Alaa

Frequency modulation (FM) is a class of analog modulation techniques that rely on varying the instantaneous frequency of a radio-frequency (RF) carrier in accordance with the baseband signal. The amplitude of the FM signal is constant, while its instantaneous frequency is time variant; therefore, the zero crossing rate (ZCR) of the carrier differs at a rate proportional to the … [Read more...] about Narrowband and wideband frequency modulation spectral characterization and bandwidth calculation

Privacy implications of facial recognition technology

Facial recognition technology (FRT) has experienced enormous growth and rapid deployment across different sectors of the society in recent years, mostly motivated by safety, security, and commercial applications. However, major privacy questions arise around this technology, and regulators are still working to provide clear set of rules governing its use. This paper focuses on privacy implications of FRT usage. Specifically, we first present the definition of FRT, followed by an analysis of the vulnerability and risks that can potentially arise and how they might be concerning in such context. Finally, we discuss efforts needed to mitigate privacy concerns related to FRT, from both technical and regulatory perspectives.
