Intergenerational gap refers to the disturbance and crisis in the cultural sequence of generations, which leads to conflict in terms of values and norms between parents and children. Until recently, this phenomenon has not been considered a serious issue in Iranian society and the continuation of similar thought patterns through the generations has prevented the emergence of distance and variou...

MOTIVATION No general theory guides the selection of gap penalties for local sequence alignment. We empirically determined the most effective gap penalties for protein sequence similarity searches with substitution matrices over a range of target evolutionary distances from 20 to 200 Point Accepted Mutations (PAMs). RESULTS We embedded real and simulated homologs of protein sequences into a d...

The desired gap headway of drivers, while close following, represents the main parameter in determining the following distance between vehicles.  This paper uses the raw individual vehicles data taken from loop detectors for millions of vehicles used M25 and M42 in order to estimate the gap headway distributions between successive pairs of vehicles.  The data used in this paper were filtered so...

The purpose of this research is to determine whether nontraditional undergraduate students in the US who enroll in distance education classes are less likely to have an enrollment gap (enrollment gap=part year enrollment). Previous research has shown that preference for distance education classes is significantly greater among nontraditional than among traditional undergraduate students; nontra...

This article presents the concept of storing optical energy using a metallic air gap microcavity. Evanescent waves are stored in the air gap of a dielectric/metal/air gap/metal planar microcavity. For an air gap with a micron scale distance between the two metals, incident light excites the optical interface modes on the two metal-air interfaces simultaneously, being accompanied by enhanced eva...

Rotor cage faults as broken rotor bars, increased bars resistance and end-ring faults can be caused by thermal stresses, due to overload, overheating and thus mechanical stresses, magnetic stresses and dynamic stresses due to shaft torques. Environmental stresses as contamination or abrasion also contributes to the rotor cage faults. The rotor cage faults can also lead to the shaft vibration an...

In induction machines, an eccentrically positioned rotor experienced a strong unbalanced pull toward the short side of the air gap. The non-symmetric flux distribution due to the eccentricity induces circulating currents in the rotor cage and parallel branches of the stator winding. These currents equalise the flux distribution and reduce the unbalanced magnetic pull. In this paper, the effects...
