Due to the fact that the error surface of adaptive infinite impulse response (IIR) systems is generally nonlinear and multimodal, the conventional derivative based techniques fail when used in adaptive identification of such systems. In this case, global optimization techniques are required in order to avoid the local minima. Harmony search (HS), a musical inspired metaheuristic, is a recently ...

neural networks are applicable in identification systems from input-output data. in this report, we analyze thehammerstein-wiener models and identify them. thehammerstein-wiener systems are the simplest type of block orientednonlinear systems where the linear dynamic block issandwiched in between two static nonlinear blocks, whichappear in many engineering applications; the aim of nonlinearsyst...

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...

a solution to the problem of identification and control of smart structures is presented in this paper. smart structures with build-in sensors and actuators can actively and adaptively change their physical geometry and properties. as a particular example, a representative dynamic model of a typical fighter vertical tail, identified as the smart fin, is considered. piezoelectric patches, which ...

abstract purpose of this paper: the objectives of this paper are two folds: (1) utilizing hierarchical fuzzy technique for order preference by similarity to ideal solution (topsis) approach to evaluate the most suitable rfid-based systems decision, and (2) to highlight key risks and benefits of radio frequency identification technology in healthcare industry. design/methodology/approach: resear...

Taxonomy is the science of naming, describing and classifying organisms that includes all plants, animals and microorganisms of the world. Using morphological, behavioral, genetic information and biochemical observations, taxonomists identify and describe species into classifications, including those that are new to science. The taxonomic identification of fishes is a time-consuming process and...

The new approach to modal parameter identification, presented in this paper, uses an asymptotically stable observer to form a discrete state-space model for a wind turbine structure. The identification is per­ formed using input-output time-series. A special software package developed in this research has been tested using the data generated by the ADAMS�1 model of the Micon 65/13 wind turbine ...

A new approach to abnormal situations with regard for the heuristic regularities of human-operator thinking process is proposed. The regularities are revealed on basis of recording the motions of the humanoperator eyes over the information field of the control board and processing the experimental data obtained. For data processing, a probability theoretical approach is utilized. Such an approa...

Microwave radiometers are valuable for obtaining geophysical information such as the ocean surface salinity, stratiform precipitation, water vapor, temperature, soil moisture, vegetation cover, and others [1]. These environmental monitoring applications of passive microwave remote sensing systems require precision measurements of brightness temperatures over a range of more than 300K with absol...
