we prove that the class of profinite groups $g$ that have a factorization $g=ab$‎ ‎with $a$ and $b$ abelian closed subgroups‎, ‎is closed under taking inverse limits‎ ‎of surjective inverse systems‎. ‎this is a generalization of a recent result by k. h. hofmann and f. g. russo‎. ‎as an application we reprove their generalization of iwasawa's structure theorem for‎ ‎quasihamiltonian pro-$p$...

trajectories generally used to describe the space and time required to perform a desired motion task for a mobile robot or manipulator system. in this paper, we considered a cubic polynomial trajectory for the problem of moving a mobile robot from its initial position to a goal position in over a continuous set of time. along the path, the robot requires to observe a certain acceleration profil...

Abstract We explore the tree limits recently defined by Elek and Tardos. In particular, we find for many classes of random trees. give general theorems three conditional Galton–Watson trees simply generated trees, split generalized (as here), a continuous-time branching process. These results include, example, labelled ordered recursive preferential attachment binary search

subgrade soil stabilization is one of the primary and major processes in the construction of any highway; also environmental authorities are concerned about the growing amount of polyethylene (pet) bottles produced by household sectors. this research in order to study effect of adding recycled polyester fiber on soil engineering properties, especially shear strength and california bearing ratio...

noise-induced hearing loss, which is one of the 10 leading occupational diseases, is a debilitating and irreversible disease. during the recent 15-years period (1997-2012), several studies have investigated the association between noise, hearing damage and other side effects of noise in iran. the aim of this study was to review systematically the relevant literature related to noise-induced hea...
