Introduction: The electromagnetic interaction between human subjects and RF coils complicates the estimation of performance and RF power deposition. Traditional full-wave simulation approaches apply generic human models that do not accurately represent individual patients. Since the interaction is strongly patient-dependent, real-time simulations that are based on patient-specific models are de...

   In this research, mesoporous silica was served as the host of molybdate (corrosion inhibitor). The loaded mesoporous silica was dispersed in a paint matrix. The composite was then coated on the carbon steel surface. Polarization and electrochemical impedance spectroscopy (EIS) tests showed that the corrosion resistance of the scratched paint containing molybdate loaded mesoporous silica ...

In the present work, four polymeric nanocomposite PNC coatings were prepared with different concentrations of yttrium aluminum garnet nanoparticles YAG-NPs in polyvinyl butyral PVB matrix. The corrosion protection of the PNC coatings applied on the carbon steel surface was investigated in 1.0 M HCl solution by electrochemical impedance spectroscopy EIS. The YAG-NPs were synthesized by pulse ele...

The development of synthesis procedures for passing from a prescribed rational positive real function or matrix to a linear lumped network of passive components possessing the prescribed quantity as its impedance has been one of the major problems confronting network theorists in the past. One of the earliest such synthesis procedures is the Brune synthesis, see Reference 1 and for more recent ...

The computational solution of large-scale linear systems of equations necessitates the use of fast algorithms but is also greatly enhanced by employing parallelization techniques. The objective of this work is to demonstrate the speedup achieved by the MPI (Message Passing Interface) parallel implementation of the Steepest Descent Fast Multipole Method (SDFMM). Although this algorithm has alrea...

Title of dissertation: STATISTICAL MODELING OF WAVE CHAOTIC TRANSPORT AND TUNNELING Ming-Jer Lee, Doctor of Philosophy, 2013 Dissertation directed by: Professor Edward Ott Professor Thomas Antonsen Department of Physics This thesis treats two general problem areas in the field of wave chaos. The first problem area that we address concerns short wavelength tunneling from a classically confined r...

This paper presents a new hybridization between MoM-GEC and a MultiResolution analysis (MR) which is based on the use of wavelets functions as trial functions. The proposed approach is developed to speed up convergence, alleviate calculation and then provide a considerable gain in requirements (processing time and memory storage) because it generates a sparse linear system. The approach consist...

This paper presents a novel impedance-based approach for out-of-step (OOS) protection of a synchronous generator. The most popular and commonly used approaches for detecting OOS conditions are based on the measurement of positive sequence impedance at relay location. However, FACTS devices change the measured impedance value and thus disrupt the performance of impedance-based relay function. In...

Adaptive multiscale moment method (AMMM) is presented for the analysis of scattering from a thin perfectly conducting plate. This algorithm employs the conventional moment method and a special matrix transformation, which is derived from the tensor products of the two one-dimensional (1-D) multiscale triangular basis functions that are used for expansion and testing functions in the conventiona...

Good robot performance often relies upon the selection of design parameters that lead to a well conditioned Jacobian or impedance " design " matrix. In this paper, a new design matrix normalization technique is presented to cope with the problem of non-homogeneous physical units. The technique pre and post-multiplies a design matrix by diagonal scaling matrices corresponding to the range of joi...
