Simultaneous ML Estimation of State and Parameters for Hyperbolic Systems with Noisy Boundary Conditions
In this paper, we present a method to estimate simultaneously states and parameters of a discrete-time hyperbolic system with noisy boundary conditions. This method is based on the maximization of a likelihood function. Although this technique is described here for linear systems, possible extensions to non-linear systems are also briefly discussed.

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...
15 صفحه اولStochastic finite element framework for simultaneous estimation of cardiac kinematic functions and material parameters
A stochastic finite element framework is presented for the simultaneous estimation of the cardiac kinematic functions and material model parameters from periodic medical image sequences. While existing biomechanics studies of the myocardial material constitutive laws have assumed known tissue kinematic measurements, and image analysis efforts on cardiac kinematic functions have relied on fixed ...
متن کاملEstimation of Material Parameters for Grid Structures
A numerical approximation scheme is developed for the identi cation of spatially varying sti ness parameters along with Kelvin-Voigt and viscous damping parameters in Love-Kirchho models for the transverse vibrations of thin, exible grids. The inverse problem is formulated as a least squares t to data. Spline-based nite element approximations are used to solve the partial di erential equation w...
متن کاملSimultaneous Parameters Estimation of Digital Modulated Signals
A maximum likelihood estimate for frequency carrier, phase leakage and amplitude of digital PSK modulated signals is presented. The three optimum parameters obtained are analyzed and compared with suboptimum realizations in the synchronization process. In order to achieve an efficient system a final structure is closed where each method is selected in order to get not only appropriated performa...
