Abstract In this paper, we first evaluate topological distributions of the sets all doubling spaces, uniformly disconnected and perfect spaces in space isometry classes compact metric equipped with Gromov–Hausdorff distance.We then construct branching geodesics distance continuously parameterized by Hilbert cube, passing through or avoiding satisfying some three properties shown above, infinite...

abstract background and purpose: priority health-risk behaviors, often are established during childhood and adolescence, extend into adulthood, and are interrelated and preventable. this study was conducted to determine and compare the prevalence of risky behaviors on both sexes of freshman students enrolled in tehran university, iran. materials and methods: this study was a descriptive-analyti...

Dendritic flux penetration is a well known phenomenon in high temperature superconductors. We investigated the conditions under which this instability can be observed in different materials. We found three qualitatively different behaviors: dendrite development above a “critical field” and up to a certain temperature, above a “critical field” with no measurable temperature dependence, or no den...

This article describes about hell in various suras the Qur'an, one of which is Surah Maryam verses 71 and 72. Unlike other verses, this verse states that everyone will come to whether he a disobedient person or believer. Regarding verse, there are differences opinion on meaning word وَارِدُهاَ means him. Some interpret it with entering. While some others passing. Imam al-Tabari commentators who pro...

In the recent works either the obstacle avoidance of robot in the 2-D unconstrained environment or the wall following behavior of mobile robot in constrained motion has been discussed. In some of them target alignment behavior has been discussed. Also the integration of some but not sufficient behaviors have been discussed in some research works. But all of the behaviors have not yet been integ...

Nowadays, a noticeable part of the relations among the states turn around the environment protection. Therefore, the right for ever-creasing use of the existing resources of this inland sea cannot be exclusive to any Caspian State and the aftermath involves all countries of this basin. In this respect, agreement on political border and boundaries with the Caspian Sea?s ecosystem is a difficul...

Charm++ may employ any of a myriad network-specific APIs for handling communication, which are usually promoted as being faster than its catch-all MPI module. Such a performance difference not only causes development effort to be spent on tuning vendor-specific APIs but also discourages hybrid Charm++/MPI applications. We investigate this disparity across several machines and applications, rang...
