In recent years, considerable effort in the field of operations research has been paid to optimizing airline operations, including the logistics of an airline’s fleet of aircraft. We focus on the problem of aircraft routing, which involves generating and selecting a particular route for each aircraft of a sub-fleet that is already assigned to a set of feasible sequences of flight legs. Similar ...

Theoretical accounts of the processing of inflectional morphology make implicit, untested assumptions about the activation of verb semantics from inflected verbs. This research used semantic priming to investigate the extent to which regular and irregular past tense forms activate verb semantics, in comparison to the verb stem. The results show that past tense forms activate verb semantics to t...

The performance of regular and irregular Gallager-type errorcorrecting code is investigated via methods of statistical physics. The transmitted codeword comprises products of the original message bits selected by two randomly-constructed sparse matrices; the number of non-zero row/column elements in these matrices constitutes a family of codes. We show that Shannon's channel capacity may be sat...

Abstract: Communication between non-adjacent processors in regular and irregular interconnection networks mostly relies on routing tables. Because the tables generally cannot be derived by means of an analytical approach, we have focused on the utilization of the hybrid parallel genetic simulated annealing algorithm HGSA [1] to design optimal or sub-optimal routing schedule for a sequence of co...

Pore network modeling uses a network of pores connected by throats to model the void space of a porous medium and tries to predict its various characteristics during multiphase flow of various fluids. In most cases, a non-realistic regular lattice of pores is used to model the characteristics of a porous medium. Although some methodologies for extracting geologically realistic irregular net...

a novel discrete singular convolution (dsc)  formulation  is  presented for the seepage analysis in irregular geometric porous media. the dsc is a new promising numerical approach which has been recently applied to solve several engineering problems. for a medium with regular geometry, realizing of the dsc for the seepage analysis is straight forward. but dsc implementation for a medium with ir...
