Filter generators are vulnerable to several attacks which have led to well-known design criteria on the Boolean filtering function. However, Rønjom and Cid have observed that a change of the primitive root defining the LFSR leads to several equivalent generators. They usually offer different security levels since they involve filtering functions of the form F (x) where k is coprime to (2 − 1) a...

We present a method to solve the Helmholtz equation for a non-homogeneous membrane with Dirichlet boundary conditions at the border of arbitrary two-dimensional domains. The method uses a collocation approach based on a set of localized functions, called ”little sinc functions”, which are used to discretize two-dimensional regions. We have performed extensive numerical tests and we have compare...

Preface I was lucky to participate in the activity of the International Center for Signal Processing of Tampere University of Technology from almost its foundation in 1997. It is a honor for me to dedicate this paper to its director, Prof. Jaakko Astola on the case of his 60 year jubilee and in appreciation of his leadership and support of research in both fundamental issues of digital signals ...

The inequ ality in the sentence in the middle of page 534 should be reversed to read "In t he single-out put version unit i was accepted as a candidate for flipping if the condition WiSiS > 0 was sa t isfied ." Sinc e our comput er codes did not contain these erro rs, no ne of our published results needs to be modified. We would also like t o acknowledge useful discussion s wit h S. Barkan and ...

In this paper we show how model–based reasoning techniques can be used to solve circumscription entailment problems without computing the circumscription axiom. We characterize the circumscription by a small subset of the minimal models computed by a revision function. Using these models a filtering function decides, whether a given formula is entailed by the circumscription. We describe, how t...

The encapsulation of antifouling compounds, such as DCOIT (4,5-Dichloro-2-octylisothiazol-3(2H)-one), in mesoporous silica nanocapsules (SiNC) has recently been demonstrated to be an eco-friendly alternative decrease biocide toxicity towards marine non-target species. However, the lack information on chronic effects nanomaterials tropical species is critical for a more comprehensive environment...

In this paper we apply a regularized sinc method to compute the eigenvalues of a discontinuous Dirac systems, which contain eigenvalue parameter in one boundary condition, with transmission conditions at the point of discontinuity. The regularized technique allows us to insert some parameters to the well known sinc method; strengthening the existing technique and to avoid the aliasing error. Th...
