extended kalman filtering (ekf) is a nonlinear dynamic data reconciliation (nddr) method. one of its main advantages is its suitability for on-line applications. this paper presents an on-line nddr method using ekf. it is implemented for two case studies, temperature measurements of a distillation column and concentration measurements of a cstr. in each time step, random numbers with zero mean ...

Bu çalışmada Ti, V, Cr, Mn, Fe, Co, Ni, Cu ve Zn element bileşiklerinin K kabuğu doğal çizgi genişlikleri ile Kα1 Kα2 X-ışını yarı deneysel olarak, kabuk flüoresans verimi değerleri kullanılarak hesaplandı. Numuneleri uyarmak için 75mCi şiddetinde 59. 5 keV enerjili gama ışınları yayınlayan 241Am radyoizotop kaynağı kullanıldı. Numunelerden yayınlanan X-ışınlarını saymak çözünürlüğü 5.96 keV'de...

A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...

In this paper, a new on-line measurement and accuracy analysis method for part configuration and surface is presented by combining computer vision and neural networks. Different from conventional contact measurement, it is non-contact measurement method, and it can operate on-line. In this method, the 3D configuration and surface of part are reconstructed from stereo image pair taken by compute...
