Mathematical model plays an important role in understanding the disease dynamics and designing strategies to control spread of infectious diseases. In this paper, we consider a deterministic SEIS with saturation incidence rate its stochastic version. To begin with, propose epidemic obtain basic reproduction number R</mi...

Visual position and velocity cues improve human standing balance, reducing sway responses to external disturbances and sway variability. Previous work suggested that human balancing is based on sensory estimates of external disturbances and their compensation using feedback mechanisms (Disturbance Estimation and Compensation, DEC model). This study investigates the visual effects on sway respon...

An effective technique for extracting an audio input from a composite signal that contains a nonstationary noise-corrupted periodic disturbance is presented. The proposed technique cancels the periodic disturbance using a synthesized signal whose parameters are adjusted adaptively. A combination of a generalized phase-locked loop (PLL) and an adaptive least mean square (LMS) method is used. The...

Noise events are well established in the measurement and management of aircraft noise. While there have been attempts to apply similar noise-event concepts to road and rail traffic noise signals for many decades, the idea has remained largely peripheral to the current paradigm of surface traffic noise measurement, assessment and management. The latter is based, almost exclusively, on metrics th...

sleep plays a vital role in regulating physiological mechanisms in the human body. nowadays, by the change of lifestyle and as a consequence of longer work hours and increased accessibility to media, sleep disturbance becomes a common problem in modern society. many studies demonstrated that sleep disturbance triggers a systemic low-grade inflammation by increasing the level of several cytokine...

Images plays vital role in our daily life. Noise is one of the important limitation in digital image processing. Noise is basically the type of unwanted disturbance in the image. A lot study is made so outlying to diminish or confiscate noise from digital images. Most of the filter fails when the noise density is very high. This paper proposes improved modified decision based median filter whic...

Observer based stochastic disturbance accommodating control scheme utilizes an estimator to determine the necessary corrections to the nominal control input and thus minimizes the adverse effects of both model uncertainties and external disturbances on the controlled system. The total control input, which includes the nominal control as well as the control corrections to the nominal control to ...

Introduction Recent research on the impacts of environmental noise on health and wellbeing can be broadly categorized by three themes. The first theme is the enduring concept of soundscapes or the sonic characteristics of indoor and outdoor environments in situated locales. Health researchers consider soundscapes as context dependent, within which perceptions of sounds can be modified by indivi...
