The identification of dynamical models in the errors-in-variables (EIV) framework has seen renewed interest during the last decades. One of the main advantages of such a framework is the symmetrical treatment of all variables. One important EIV identification method is the Frisch scheme, which yields estimates for the measurement noise variances as well as the model parameters. Building on a re...

تحلیل وضعیت ترافیکی و پیشنهاد روش‌های مدیریت جریان ترافیک نقش اساسی در ارزیابی عملکرد بسیاری از سیستم‌های حمل‌ونقلی ایفا می‌کند. بین جمع‌آوری داده‌های ترافیکی، رویکردهای مبتنی‌بر فنّاوری‌های نوین که امکان گرد‌آوری حجم پویای زمانی‌ـ مکانی را فراهم می‌آورند استخراج روندها الگوها تسهیل می‌کنند اهمیت دارند. این پژوهش، تهران به‌منزلة پایتخت ایران، با ویژگی‌های اقتصادی اجتماعی خاصی دارد تنوع سفرها به ...

This new paper combines errors-in-variable (EIV) system with closed loop situation to consider a more complex EIV system. Consider the identification problem for system, synthesis analysis is completed from point of field. Firstly, reason about why useful in academy and practice explained detail. Secondly, identify that unknown plant, existing measurement process noise simultaneously, nonparame...

Two binding sites for EivF, a factor involved in transcription from the adenovirus early promoter iv (Eiv), were mapped within the adenovirus inverted terminal repeats (ITR). Consistent with the observation that EivF was required to initiate transcription from the Eiv promoter and with the demonstration that two EivF binding sites were present in the ITR, we show that the inverted terminal repe...

Abstract: Easily computable recursive algorithms are proposed for estimating coefficients of A(z), C(z), and the covariance matrix Rw of wk for the multivariate ARMA process A(z)yk = C(z)wk on the basis of the noise-corrupted observations ηk ∆ = yk + ǫk. It is shown that the estimates converge to the true ones under reasonable conditions. An illustrative example is provided, and the simulation ...

BACKGROUND Equine influenza virus (EIV) epizootics affect 2.1 million Mongolian horses approximately every 10 years and critically impact economy and nomadic livelihood of Mongolia. OBJECTIVES An active surveillance program was established in 2011 to monitor influenza viruses circulating among Mongolian horses. METHODS Nasal swabs were collected from horses in free-ranging horse herds in Tö...

Total least-squares (TLS) adjustment is used to estimate the parameters in the errors-in-variables (EIV) model. However, its exact solution is rather complicated, and the accuracies of estimated parameters are too difficult to analytically compute. Since the EIV model is essentially a non-linear model, it can be solved according to the theory of non-linear least-squares adjustment. In this cont...

Abstract M split estimation is a method that enables the of mutually competing versions parameters in functional observation models. In presented study, classical models found it are replaced by errors-in-variables (EIV) Similar to weighted total least-squares (WTLS) method, random components these were assigned covariance matrix Thus, proposed named Total (TM ) estimation, corresponds basic ru...
