The world has witnessed a major uproar in the year 2020 with widespread transmission of COVID-19. propensity for wearing face mask become essential as countermeasure against infection particularly open settings where keeping up social distancing is not functional more often than not. As result, crucial to curb spread pandemic. This paper concerned simplified approach detection real-time using convolutional neural networks (CNN) and Open-CV. proposed CNN model trains on dataset 12000 images...

This article presents the estimation of electric and magnetic fields using Kalman filter (KF). The in entire space have been estimated scalar vector potential. For this estimation, measurements at a sparse discrete set spatial pixels used. To implement KF, state model has obtained wave equations with sources satisfied by proposed method implemented on Hertzian dipole antenna. KF compared recursive least squares (RLS) method. better than RLS, as it is an optimal estimator. work uses Kronecker...

In our modernized world, even though we have come a long way in technological advancement, healthcare industry is still burdened with giving proper medical assistance to patients and saving their lives. This burden especially overwhelming the ICU. Currently sector uses various health scores like APACHE [6], SAPS, SOFA etc assess illness of patient. But this method proving inefficient as it needs be maintained by staffs regularly since process manual, there several cases where wrong or...

Purpose This paper aims to present the estimation of output voltage metal oxide semiconductor field effect transistor (MOSFET) using extended Kalman filter (EKF) method. Design/methodology/approach The method uses EKF for MOSFET estimation. To implement method, state space model has been obtained Kirchhoff’s current law and Enz-Krummenacher-Vittoz circuit.

Image fusion techniques are divided into two broad categories: spatial domain and transform domain. Principal component analysis (PCA) is a technique which computationally simpler reduces redundant information but has the demerit of spectral degradation. Lifting wavelet (LWT) an adaptive design demands less memory. In this paper, new hybrid algorithm been introduced combines LWT PCA in parallel manner. These methods applied on Infrared Visible images. The method then compared with...

This paper presents the nonlinear modelling of differential amplifier (DA) circuit. The derivation Volterra series using transistor nonlinearities and perturbation theory. MATLAB simulations demonstrate usefulness nonlinearity consideration. Derived expression can be used as a model for designing, simulation analysis new circuits in software like SIMULINK.

This paper presents the parameter estimation of second order resistor-capacitor (RC) low pass filter (LPF) circuit by modeling ordinary differential equation (ODE) into stochastic equations and using recursive least squares (RLS) method. In this work, at first, deterministic model RC has been derived. Then, is converted adding white Gaussian noise to input source elements. Thereafter, RLS method used for output voltage estimation. MATLAB simulation results show that estimated gives...

Due to increased lifespan and the rapid development of chronic diseases, there is a growing demand for disease-related healthcare. The dramatic increase Covid-19 lead growth digital healthcare driven by technology improve patient satisfaction. present study attempts understand how different types health care bring satisfaction, concept Telemedicine finally, presents primary survey-based evidence satisfaction as result using WHOQOL-BRIEF Patient Satisfaction Assessment

This paper implements the stochastic filters for state and parameter estimation of nonuniform transmission lines (NTL). In general, line (TL) problem is a continuous time space problem. By taking loading noise into account, TL equations become partial differential equation (PDE) rather than simple set coupled finite (SDE). transforming spatial variables Fourier domain, PDE can be transformed an infinite sequence SDE. After truncation to series coefficients, it becomes linear SDE, which...

This paper presents Volterra model of silicon controlled rectifier (SCR). As the SCR circuit nonlinearities appear due to transistors, we used classical mathematical model, namely, Ebers-Moll together with perturbation theory obtain closed form expressions between input and output SCR. The derived equations can be as a in SIMULINK for designing, analysis development new integrated circuits advance before formation chips. also parameter estimation purpose. are useful software, this software...
