Optical Heating Ability of Er3+-Yb3+ Embedded TeO2-WO3 Glass for Thermometric Applications
Abstract: The present research work details laser-induced optical heating ability of the Er3+-Yb3+ embedded TeO2-WO3 glass prepared by the melt-quenching process. The green upconversion emission observed through the 2H11/2→4I15/2 and 4S3/2→4I15/2 transitions of Er3+ ion upon 980 nm diode laser excitation was used to employ fluorescence intensity ratio technique. The results obtained from temperature sensing study were utilized to monitor temperature against pump power provided. The internal heating generated up to …

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 …

Health Monitoring Iot Based Virus Fever Detection System Using Non Inversive Method
Abstract: Health monitoring IoT to detect and count platelet to diagnose virus Fever this reduces labour intensive, time and cost. Vital signs are indicators of the body's fundamental processes. Body temperature, heart rate, breathing rate, and respiration are the four primary vital indicators that healthcare professionals regularly check (respiration). They can be measured in a hospital, at home, during an emergency medical situation, or while travelling. On-invasive blood related parameters covering …

Bluetooth Based Wireless Digital Stethoscope with Mobile Integration
Abstract: AbstractAcoustic stethoscopes operate on the transmission of sound from the chest piece, via air-filled hollow tubes, to the listener's ears. In the stethoscope, the chest piece and the connecting cable are known to facilitate transmission of pathogens from patient to patient and from patient to the user. Replacing the connecting cable with a wireless system may help reduce the potential risk and further allow broadcasting of the signals to multi-user …

Evaluation of OTA Amplifier Using EEG Signals
Abstract: AbstractOver the last few years, there has been a tremendous exploration in VLSI industries in response to scaling trends towards deep submicron technology. Demand for low power and efficient amplification are rising in day-to-day life. In the process of scaling the CMOS nanometer demand low supply, which is helped to design digital circuit realization at very low power consumption. But it is not valid for analog circuit realization. The related …
