Zernike Moments are useful tools in pattern recognition and image analysis due to their orthogonality and rotation invariance property. However, direct computation of these moments is very expensive, limiting their use especially at high orders. There has been some efforts to reduce the computational cost by employing quantized polar coordinate systems, which also reduces the accuracy of the mo...

An accurate delay model has been developed and integrated in a delay-fault test-pattern generator. The approach is based on extensive multi-input logic gate timing characterisation and layout extraction for interconnection wiring delays. The generator is capable of detecting small delay faults in combinational as well as sequential circuits. It provides the optimal observation times for detecti...

This paper presents a novel mixed-signal verification methodology for jitter tolerance in highspeed serial-link receiver designs. The predictive approach includes identifying the jitter sources at the receiver input, generating the artificial jitter to add on input data and clock, and investigating the jitter sensitivities inside the receiver with bit error indicator. Both an artificial jitter ...

SUMMARY We propose the use of high-order weighted essentially non-oscillitory interpolation and moving-least-squares approximation schemes alongside high-order time integration to enable high-order accurate particle-in-cell methods. The key insight is to view the unstructured set of particles as the underlying representation of the continuous fields; the grid used to evaluate integro-differenti...

In this paper we discuss the relationship between prospective and retrospective sampling problems. Estimates of the parameter of interest may be obtained by solving suitable estimating equations under both sampling schemes. Most common examples of such estimates include the maximum likelihood estimates. Some classical results and more recent development of the rst-order asymptotic relationship ...

High-order methods inspired by the multi-step Adams methods are proposed for systems of fractional differential equations. The schemes are based on an expansion in a weighted L space. To obtain the schemes this expansion is terminated after P + 1 terms. We study the local truncation error and its behavior with respect to the step-size h and P . Building on this analysis, we develop an error ind...
