We give a general overview of the state-of-the-art in subspace system identification methods. We have restricted ourselves to the most important ideas and developments since the methods appeared in the late eighties. First, the basis of linear subspace identification are summarized. Different algorithms one finds in literature (Such as N4SID, MOESP, CVA) are discussed and put into a unifyin...

The problem of blind channel identification for direct-sequence/code-division multiple-access (DS/CDMA) multiuser systems is explored. For wideband DS/CDMA signals, multipath distortion is well modeled by a finite-impulse response filter. In this work, a blind channel identification technique based on second-order statistics is investigated. The method exploits knowledge of the spreading code o...

This paper presents a template aging study of eye movement biometrics, considering three distinct biometric techniques on multiple stimuli and eye tracking systems. Short-to-midterm aging effects are examined over two-weeks, on a highresolution eye tracking system, and seven-months, on a low-resolution eye tracking system. We find that, in all cases, aging effects are evident as early as two we...

Since the nanoindentation technique is able to measure the mechanical properties of extremely thin layers and small volumes with a high resolution, it also became one of the most important testing techniques for thin polymer layers and coatings. This work is focusing on the characterization of polymers using nanoindentation, which is dealt with by means of numerical computation, experiments and...

The status of an ongoing project to identify a full-envelope model of the YAV-8B Harrier using flight-test and parameter identification techniques is described. As part of the research in advanced control and display concepts for V/STOL aircraft, a full-envelope aerodynamic model of the YAV-8B will be identified. Mathematical model structures and parameter identification methods that are being ...

This paper addressed some theoretical and practical issues relevant to the problem of power system load modeling and identification. An identification method is developed in the theoretical framework of stochastic system identification. The identification method presented in this paper belongs to the family of output error models and is based on well-established equations describing load recove...

Fish species identification process is still problematical and time consuming, so automated fish important. The performance of various techniques compared depending on pre-processing, number significant characteristics correctness. reason for writing this review stems from the importance humans as food a wealth which support economy countries. Therefore, it necessary to shed light how distingui...
