A multirepeat in a string is a substring (factor) that appears a predefined number of times. A multirepeat is maximal if it cannot be extended either to the right or to the left and produce a multirepeat. In this paper, we present algorithms for two different versions of the problem of finding maximal multirepeats in a set of strings. In the case of arbitrary gaps, we propose an algorithm with ...

The two independent Mn(II) ions in the polymeric title compound, {[Mn(2)(C(6)H(2)N(2)O(4))(C(10)H(8)N(2))(H(2)O)(6)]SO(4)·3H(2)O}, exhibit distorted MnN(2)O(4) octa-hedral coordination geometries, with the pyrimidine-4,6-dicarboxyl-ate (pmdc) ligand acting in the bis-chelating μ-(κO,κN:κO',κN') bridging mode and the 4,4'-bipyridine (bpy) ligand in the μ-(κN:κN') bridging mode. The remaining coo...

This paper proposes a novel approach for an optimal multi-objective optimization for VLSI implementation of Artificial Neural Network (ANN) which is area-power-speed efficient and has high degree of accuracy and dynamic range. A VLSI implementation of feed forward neural network in floating point arithmetic IEEE-754 single precision 32 bit format is presented that makes the use of digital weigh...

Ferroalloys are one of the most important raw materials widely used in steelmaking processes. Depending on cleanliness ferroalloys, they can be an inevitable source impurities and nonmetallic inclusions (NMIs) products. Herein, five different industrial ferroalloys (FeTi, FeMo, FeW, MnN, FeCrN) investigated. This is done using 2D investigations polished cross sections ferroalloy samples 3D NMIs...

ARTIFICIAL neural network (NN) architectures have been recognized for a number of years as a powerful technology for solving real-world image processing problems. The primary purpose of this special issue is to demonstrate some recent success in solving image processing problems and hopefully to motivate other image processing researchers to utilize this technology to solve their real-world pro...
