Human Deep Skin Surface Vibration Frequency Detection from CT and DT Signals Using Genetic Algorithms
Abstract: To diagnose respiratory problems early on, a contactless, non-invasive, real-time assessment of human vibration is a crucial prerequisite. Optoelectronic plethysmography (OEP) and the forced oscillation technique (FOT), are two widely utilized methodologies, depending on variations in each patient’s local chest impedance. Calibration of the devices before each measurement is hence the primary problem of these approaches. This report presents a simulation-based analysis to assess the effectiveness of the CT and …

Intelligent Electromagnetic Braking System
Abstract: AbstractThe principle of conventional braking system involves the conversion of kinetic energy into heat. It uses development of contact friction for retardation. When the brake is applied, the brake shoes having a friction material lining are forced by hydraulic wheel cylinders against the inner surface of a rotating drum. The result of this contact produces friction, enabling the vehicle to slow down and stop. The design consideration is such that …
