In this study, a multiscale monitoring method for nonlinear processes was developed. We introduced machine learning tool fault detection and isolation based on the kernel principal component analysis (PCA) discrete wavelet transform. The principle of our proposal involved decomposing multivariate data into coefficients by employing Then, PCA applied every matrix to detect defects. Only those sc...

Manipulating the polarization states of electromagnetic (EM) waves, a fundamental issue in optics, attracted intensive attention recently. However, most of the devices realized so far are either too bulky in size, and/or are passive with only specific functionalities. Here we combine theory and experiment to demonstrate that, a tunable metasurface incorporating diodes as active elements can dyn...

Efficiency of Orthogonal Frequency-Division Multiplexing (OFDM) system is improved by reducing the power consumed by its transmitter and also by improving the spectral efficiency. Power usage is reduced by reducing the PAPR of OFDM system and spectral efficiency is improved by Adaptive modulation and coding schemes (AMC). In OFDM system, transmission signals can have high peak values in the tim...

Recent subcritical VENUS-F experiments showed that fission chambers with a threshold deposit like U-238 can essentially improve the on-line sub-criticality measurments beam interruption method, which is currently supposed to be main method for ADS MYRRHA. To suppress uncertainty caused by fissions in U-235 impurities, fraction of U should accurately known. Three PHOTONIS CFUL01 type were purcha...

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

Our system allows the formal verification of digital circuits using specifications expressed in English. Verification is carried out by the SMV model checker program [McM92]. SMV requires specifications to be written in the temporal logic CTL (computation tree logic). SMV’s model checking algorithm carries out inference over CTL formulas, with respect to a formal representation of a circuit. Th...
