The mating state between a flange bore and a shaft and the position error for a flange shaft in a bore has an important influence on the assembly accuracy of precision products.In view of the fact that three-dimensional cylindricity was usually ignored in existing researches,a contact method was developed,which was based on equal vector judgment cr
In this paper, a discrete variant of TLBO (DTLBO) is proposed for solving the traveling salesman problem (TSP).In the proposed method, an effective learner representation scheme is Gift Card redefined based on the characteristics of TSP problem.Moreover, all learners are randomly divided into several sub-swarms with equal amounts of learners so as
A summary of current knowledge on successful responses to cyberbullying differentiating between three different response domains: reducing risks, combatting the problem, and buffering negative impact.A systematic literature search yielded Footwear thirty-six relevant studies, most of which report findings regarding general prevention strategies (e.
A considerable potential advantage of manufacturing electric and thermoelectric devices using endohedral metallofullerenes (EMFs) is their ability to accommodate metallic moieties inside their cavities.Published experimental and theoretical works have explained the usefulness of this resilience feature for improving the electrical conductance and t
