Fingerprint matching is one of the most important modules in automatic fingerprint identification systems (AFIS). Traditional methods treat this problem as point pattern matching, which is essentially an intractable problem. In this article, we propose an effective fingerprint matching algorithm based on error propagation. First, we find initial correspondence according to the ridge information...

Particle track reconstruction capabilities of the silicon tracking detector system have been studied. As the multiple Coulomb scattering (MCS) induces unavoidable uncertainties on the coordinate measurement, the corresponding error estimates and the associated correlations have been used to find the best track fit parameters and their errors. Finally it permits to find the proper particle chara...

Diffused infrared transmission is one of the preferred techniques used in indoor wireless communications. Tolerance to shadowing and a lack of alignm ent requirements are among the many advantages offered by this technique compared to the line-of-sight techniques. However, it has its disadvantages, namely high path loss and multipath dispersion. The limitation imposed by eye-safety requirements...

Recently, a variety of workflow patterns has been proposed focusing on specific aspects like control flow, data flow, and resource assignments. Though these patterns are relevant for implementing Business Process Modeling (BPM) tools and for evaluating the expressiveness of BPM languages, they do not contribute to reduce redundant specifications of recurrent business functions when modeling bus...

Direct Sequence (DS) Code Division Multiple Access (CDMA) systems are considered for a variety of wireless applications and services because DS-CDMA enables the transmission of multimedia messages such as voice, data and video. The performance of Quasisynchronous DS-CDMA (QSCDMA) communication system with a maximal ratio combiner (MRC) over a frequency selective time non-selective multipath Gen...

A correlation processor based on the excellent periodic autocorrelation properties of maximal-length pseudorandom binary sequences has been used in antenna pattern measurements to resolve the direct (wanted) path from any unwanted multipath components. A simple implementation of the technique has been used to make measurements in a controlled environment; the results show that the multipath eff...

Angular dispersion is the effect of a multi-path propagation observed in received signals. An assessment of this phenomenon is particularly important from the viewpoint of emerging fifth generation (5G) communication systems. In these systems, using the beam-forming and massive multiple-input multiple-output antenna arrays are planned. This phenomenon also has a negative impact on direction fin...

During morphogenesis regular patterns often develop behind a frontier of pattern formation which travels across the prospective tissue. Here the authors consider the propagating patterns exhibited in a two-dimensional domain by a tissue interaction mechanochemical model for skin pattern formation. It is shown that the model can exhibit travelling waves of complex spatial pattern formation. Two ...

Emerging Patterns (EPs) are a data mining model that is useful as a means of discovering distinctions inherently present amongst a collection of datasets. However, current EP mining algorithms do not handle attributes whose values are asscociated with taxonomies (is-a hierarchies). Current EP mining techniques are restricted to using only the leaf-level attribute-values in a taxonomy. In this p...

We show the similarity between belief propagation and TAP, for decoding corrupted messages encoded by Sourlas's method. The latter is a special case of the Gallager error-correcting code, where the code word comprises products of J{ bits selected randomly from the original message. We examine the efficacy of solutions obtained by the two methods for various values of J{ and show that solutions ...
