Multi-modal biometric fusion is more accurate and reliable compared to recognition using a single biometric modality. However, most existing fusion approaches neglect the influence of the qualities of the biometric samples in information fusion. Our goal is to advance the state-of-the-art in biometric fusion technology by providing a more universal and more accurate solution for personal identi...
Objective(s): Alternative normalization methods were proposed to solve the biased information of SPM in the study of neurodegenerative disease. The objective of this study was to determine the most suitable count normalization method for SPM analysis of a neurodegenerative disease based on the results of different count normalization methods applied on a prepared digital phantom similar to one ...
We give a simple example to show that a result on the equivalent singular points of systems of ordinary linear differential equations due to G. D. Birkhoff [3; 5, pp. 252-257] needs amendment. In matrix notation, in which Y, P, etc. denote nXn matrix-valued functions of a complex variable z, this result is as follows. A. Result. Every linear differential system (1) Y'(z) = P(z)Y(z) with a singu...
We construct an elliptic curve over the eld of rational functions with torsion group Z/2Z × Z/4Z and rank equal to 4, and an elliptic curve over Q with the same torsion group and rank 9. Both results improve previous records for ranks of curves of this torsion group. They are obtained by considering elliptic curves induced by Diophantine triples.
Network traffic have several attributes with different range of values. These attributes can be qualitative or quantitative in nature. Attributes with large values significantly influence the performance of intrusion classifier making it bias towards them. Attribute normalization eliminates such dominance of the attributes by scaling the values of all the attributes within a specific range. The...
In this paper we present an approach to score aggregation for specialized search systems. In our work we focus on document ranking in scientific publication databases. We work with the collection of scientific publications of the CERN Document Server. This paper reports on work in progress and describes rank aggregation framework with score normalization. We present results that we obtained wit...
A reformulation of Walker’s theorem on the cancellation of Z says that any two homomorphisms from an abelian group B onto Z have isomorphic kernels. It does not have a constructive proof, even for B a subgroup of Z3. In this paper we give a constructive proof of Walker’s theorem for B a direct sum, over any discrete index set, of groups of the following two kinds: finite-rank torsion-free group...
