We employ the variational formulation and the Euler-Lagrange equations to study the steady-state error in linear non-causal estimators (smoothers). We give a complete description of the steady-state error for inputs that are polynomial in time. We show that the steadystate error regime in a smoother is similar to that in a filter of double the type. This means that the steady-state error in the...

the solutions of mathematical models for the estimation of the kinetic, and biokinetic parameters of naphthalene, anthracene and pyrene during degradation in surface and subsurface soils are presented in this work. the models were developed using the twin concepts of rate-determining step and steady-state approximation method. they described the biodegradation of single and a mixture of polycy...

Quadrotor control has been noted for its trouble as the consequence of the high maneuverability, system nonlinearity and strongly coupled multivariable. This paper deals with the simulation depend on proposed controller of a quadrotor that can overcome this trouble. The mathematical model of quadrotor is determined using a Newton-Euler formulation. Fractional Order Proportional Integral Derivat...

introduction: the prevalence of hearing loss in neonates is 2-5 out of every 1,000 live births. global health committee, american academy of otolaryngology, and american academy of pediatrics have recommended that hearing loss in infants be identified, and treated when possible, prior to 6 months of age. this study was designed with the aim to screen the hearing of neonates in mashhad, iran. me...

In the preceding chapter, the different statistical tests for detecting the presence of gross errors and the methods for identifying a single gross error in the data were described. For a well maintained plant, we should generally not expect more than one gross error to be present in the data. Therefore, a fundamental pre-requisite of any gross error detection strategy is that it should have go...

The meticulousness of safety critical control system design has always been of vital significance as even a trifling glitch in the design analysis may result in grievous penalties, even in the loss of human life. To ensure the correctness of the system, traditionally it based on paper and pencil proofs. With the beginning of the modern age, simulations and computer algebra systems were employed...

The steady state solution of the Euler equations of inviscid ow is computed by an adaptive method. The grid is structured and is re ned and coarsened in prede ned blocks. The equations are discretized by a nite volume method. Error equations, satis ed by the solution errors, are derived with the discretization error as the driving right hand side. An algorithm based on the error equations is de...

The experimental investigation of material flow in rotary drums is studied. An equipment in the size of pilot-scale was used to collect experimental data for investigation of validity of the conventional steady-state model of material flow in rotary drums. Also, the transient data of the time required for material movement in the empty drum up to any specified cross section are also reported. T...

Background and objectives: Risk-adjusted Bernoulli control chart is one of the main tools for monitoring multistage healthcare processes to achieve higher performance and effectiveness in healthcare settings. Using parameter estimates can lead to significantly deteriorate chart performance. However, so far, the effect of estimation error on this chart in which healthcare ...

Today, DC motors is still being used globally due to their easy speed controllability. In this article, an Adaptive Neuro-Fuzzy Inference System (ANFIS) controller is designed for DC motors. The main purpose of performing such task is to reduce the DC motor starting current and deleting the ripple current during starting time in considering control parameters such as: rise time, settling time, ...
