A discrete wavelet transform based dynamic supply current analysis technique for detecting the catastrophic faults in analog circuits containing transistor is investigated in the paper. Some considerations due to a problem of fault localization using multiresolution approximation and the illustrative numerical example are presented.

We study oscillatory behavior of a class of fourth-order neutral differential equations with a p-Laplacian like operator using the Riccati transformation and integral averaging technique. A Kamenev-type oscillation criterion is presented assuming that the noncanonical case is satisfied. This new theorem complements and improves a number of results reported in the literature. An illustrative exa...

Background Contrast enhanced MRA is a well validated and widely used technique for noninvasive vascular imaging. Significant advances in coil development, parallel imaging, and view-sharing techniques can enable imaging with very high spatial and/or temporal resolution which can be tailored to very specific or problematic clinical situations. Cartesian acquisition with projection like reconstru...

We describe a time-resolved monitoring technique for heterogeneous media. Our approach is based on the spatial variations of the cross-coherence of diffuse waves acquired at fixed positions but at different dates. The technique applies to all kind of waves, provided that waveforms can be acquired with a sampling frequency much larger than the wave frequency. To locate and characterize a weak ch...

In medical visualization of surface information, problems often arise when visualizing several overlapping structures simultaneously. There is a trade-off between visualizing multiple structures in a detailed way and limiting visual clutter, in order to allow users to focus on the main structures. Illustrative visualization techniques can help alleviate these problems by defining a level of abs...

An overview of the transformation electromagnetics/optics design technique is presented. Illustrative example designs for invisibility cloaks, beam control devices, lenses as well as applications to radiation problems are shown. Quasi-conformal transformations in two dimensions and their applications to cloaks and virtual arrays are discussed.

Abstract— A generalization of the L2-gain inequality based on nonlinear gains is considered. Using optimization and dynamic programming to characterize lower bounds for the minimal gain function for which this nonlinear L2-gain inequality holds, a technique for computation of nonlinear L2gain bounds is proposed. Some simple illustrative examples are explored.

A class of trilinear differential operators is introduced through a technique of assigning signs to derivatives and used to create trilinear differential equations. The resulting trilinear differential operators and equations are characterized by the Bell polynomials, and the superposition principle is applied to the construction of resonant solutions of exponential waves. Two illustrative exam...

introduction: the increasing development of software in e-learning has opened a new horizon in education. the current research was conducted to assess the effect of web-based teaching of anatomy course on medical students’ attitude, perceived ease of use, perceived benefit and satisfaction with teaching method at kermanshah university of medical sciences. methods: the present study was an inter...

in this manuscript a new method is introduced for solving fractional differential equations. the fractional derivative is described in the caputo sense. the main idea is to use fractional-order legendre wavelets and operational matrix of fractional-order integration. first the fractional-order legendre wavelets (flws) are presented. then a family of piecewise functions is proposed, based on whi...
