A significant limit to current understanding of cold coast evolution is the paucity of field observations regarding development of rocky coastlines and, in particular, lack of precise recognition of mechanisms controlling rock coast geomorphology in polar climates. Results are presented from a pilot survey of rock resistance using Schmidt Hammer Rock Tests (SHRT) across the recently deglacieriz...
We describe a method to investigate the mode shapes in turbulent pipe flow at a given wavenumber pair that are most responsive to harmonic forcing in the sense that the they correspond to the largest singular value in a Schmidt decomposition of the linear NavierStokes operator using the turbulent mean profile as the base flow. The ideas follow logically from the work of Sharma & McKeon (2009), ...

Water hammer is one of the unsteady flows in urban water distribution networks, which has been of great importance due to the damage caused to the pipeline and has always been of interest to researchers. In this study, the phenomenon of water hammer due to the sudden closure of the valve in the downstream end has been investigated in a laboratory and using a numerical model. In the laboratory s...
از انواع جریانهای هیدرولیکی در لولهها، جریانهای میرا است که به طور خاص ضربه قوچ نامیده میشود. جریانهای میرا از یک حالت ماندگار شروع شده و به وضعیت ماندگار دیگری خاتمه پیدا میکنند. روشهای محاسبه متعددی جهت بررسی پدیده ضربه قوچ از سال 1950 معرفی و به کار برده شدهاند. یکی از کاربردیترین روشها، معادله ژاکوفسکی میباشد که به عنوان روش حل دستی انتخاب گردیده است. از آنجائی که اغلب نرمافزار...
Odontomutilla listopadovi sp. n. is described and illustrated from Myanmar (Mandalay Region). A female of new species (male unknown) strikingly differs congeners by having two golden spots located transversely in the basal half second metasomal tergum (lacking such or 1(3) other genus). The genus Ashmead, 1899 newly recorded Myanmar. Three wrongly me species: Krombei¬nidia margheritae (Hammer, ...
We consider the Schmidt decomposition of a bipartite density operator induced by the Hilbert-Schmidt scalar product, and we study the relation between the Schmidt coefficients and entanglement. First, we define the Schmidt equivalence classes of bipartite states. Each class consists of all the density operators (in a given bipartite Hilbert space) sharing the same set of Schmidt coefficients. N...
