While adaptive filtering is in principle intended for tracking non-stationary systems, most adaptive filtering algorithms have been designed for converging to a fixed unknown filter. When actually confronted with a non-stationary environment, they possess just one parameter (stepsize, forgetting factor) to adjust their tracking capability. Virtually the only existing optimal approach is the Kal...

In recent decades, great interest among researchers is the phenomenon of radiation adaptive response (AR) [1]. Its essence lies in the fact that prior exposure to low doses leads to increased stability of the object to the late effects of radiation in large doses of damaging. It is known that reactive oxygen species (ROS) are involved in the induction of AR, they activate a signal transduction ...

an adaptive version of growing and pruning rbf neural network has been used to predict the system output and implement linear model-based predictive controller (lmpc) and non-linear model-based predictive controller (nmpc) strategies. a radial-basis neural network with growing and pruning capabilities is introduced to carry out on-line model identification.an unscented kalman filter (ukf) algor...

Introduction and purpose 
 Allergic rhinitis (AR) is a widely prevalent condition which affects mainly children. The disease not as severe other allergic disorders; however, its symptoms significantly impact the patient's quality of life. therapeutic options have limited effectiveness they are burdened with numerous side effects. In addition, AR’s underlying causes fully elucidated; thus, ...

introduction the compounds known as β-adrenergic agonists (β-aa) are organic molecules that have the ability to bind to β-adrenergic receptors (β-ar) and start biochemical reactions that will result in increase of accretion of skeletal muscle and reduction in accretion of fat. the anabolic responses to β-aa are temporary, with a peak time occurring during the first 14 days, after which there is...

Background: Allergic diseases have increased during the past decade worldwide. Th2 type lymphocyte response is known to play an important role in the process of allergic inflammation. IL-4, a mediator of type II cytokine response increases IgE synthesis and Interferon gamma, a cytokine of type I response interferes with IL-4 and inhibits IgE production. Selenium is an essential component of glu...

In this paper, we present a new method for on-line identification of time-varying FIR channels. Two conditionally coupled estimators are proposed. In both cases an augmented-state adaptive Kalman filter is employed for tracking the time-varying channel and estimating the mean channel response. Coupled to the Kalman filter is an algorithm for estimating the parameters of the underlying auto-regr...

Tree water transport and utilization are essential for maintaining ecosystem stability in seasonally arid areas. However, it is not clear how Platycladus orientalis absorbs, consumes via transpiration, stores under varying precipitation conditions. Therefore, this study used stem sap flow thermal dissipation probes hydrogen oxygen isotope tracing technology to observe different control treatmen...
