outbreak of 2009 european sovereign debt (leverage) crisis has been one of the most crucial economic events of recent years. accordingly, researchers devoted a great deal of efforts to elucidate origins and consequences of this crisis, particularly focusing on its potential effect on international trade flows. yet in the literature, there have been rare studies on exploring the effects of sover...

abstract one of the most important sources of drinking and agricultural water needs is rivers. one of the oldest methods of getting water from rivers that still has the greatest use is the gravity intake. in this type of intake, due to the disproportionate velocity at the upstream and downstream mouth of intake, occur flow separation and following sedimentation at the upstream mouth. in this st...

translation is of the most striking manifestations of contemporary arabic literature.this phenomenon in contemporary western criticism of the discussions that influenced this effect is  due to communication and connection with the arab literature and  west.            contemporaneous cash and cash schools, especially schools divan court are external factors affecting research. but the important...

In traffic engineering to effectively distribute traffic flows over multiple network paths, taking into account traffic characteristics for individual flows is vital in appropriately assigning flows to network paths for achieving better delay performance of the total traffic. All flows assigned to a path, in which some flows are heavily bursty, equally experience a significant queuing delay whe...

the developing turbulent flow in an open channel is a complex three-dimensional flow influenced by the secondary currents and free surface effects and is, therefore, not amenable to analytical solution. this paper aims to study the impact of three key hydraulic parameters (relative roughness, the froude number and the reynolds number) on the establishment length using computational fluid dynami...

In this paper we consider the optimal structure of double bracket flows and generalisations of these flows to more complex gradient flows. We discuss different notions of optimality and the relationship of the flows to the structure of convex polytopes.

We examine the impact of cross-border bank flows on recipient countries’ systemic risk. Using data on bank flows from 26 source countries to 119 recipient countries, we find that bank flows are associated with improved financial stability (i.e. lower systemic risk) in the recipient country. The impact of bank flows is stronger in recipient countries with weak regulatory quality and fragile bank...

To avoid a congestion collapse, network flows should adjust their sending rates. Adaptive flows adjust the rate, while unresponsive flows do not respond to congestion and keep sending packets. Unresponsive flows waste resources by taking their share of the upstream links of a domain and dropping packets later when the downstream links are congested. We use network tomography—an edge-to-edge mec...
