Generalized compound matrix method
In this work we demonstrate how the extension of the Evans function method using the compound matrix approach can be implemented to undertake the stability analysis (normally done through numerical means) of nonlinear travelling waves. The main advantage of this approach is that it can easily overcome the stiffness which is normally associated with these kinds of problems. We present a general ...
متن کاملTesting for Tautology based SQL Injection Attack using Runtime Monitors
Today, all commercial and business applications (ecommerce, banking, blogs, web mail, etc.,) are built as webbased database applications. Increasing prominence and usage of these applications has made them more susceptible to attacks because they store huge amount of sensitive user information. Traditional security mechanisms like network firewalls, intrusion detection systems, and use of encry...
متن کاملExperiments with a Tautology Checking Algorithm
This paper presents various versions of a tautology checking algorithm that is related both to St̊almarck’s algorithm and the mechanism described by Kunz and Stoffel in Reasoning in Boolean Networks[KS97]. The algorithm uses as its central data structure the conjunction of a set of terms, with each term being a relation over a small number of variables. In St̊almarck’s algorithm the relation is l...
متن کاملSignificant Reduction of Gibbs’ Overshoot with Generalized Sampling Method
As is well-known, the use of Shannon sampling to interpolate functions with discontinuous jump points leads to the Gibbs’ overshoot. In image processing, it can lead to the problem of artifacts close to edges, known as Gibbs ringring. Its amplitude cannot be reduced by increasing the sample density. Here we consider a generalized Shannon sampling method which allows the use of timevarying sampl...
متن کاملCorrections to generalized Petri net reduction method
Let PN be the number of logical operations needed for constructing all lconv tables for an N bit image. We denote such a lconv table as LCTABLE( N ) . PN can be calculated on the basis of PNcorresponding to LCTABLE( N 1). The first row in the LCTABLE( N ) requires N more logical operations than Phijust for a given first bit of the N-bit threshold value. There are two cases (either “0” or “1”) f...
