An h-layer drawing of a graph G is a planar drawing of G in which each vertex is placed on one of h parallel lines and each edge is drawn as a straight line between its end-vertices. In such a drawing, we say that an edge is proper if its endpoints lie on adjacent layers, flat if they lie on the same layer and long otherwise. Thus, a proper h-layer drawing contains only proper edges, a short h-...

Abstract The effective thermal expansion coefficient β∗ of a binary viscoelastic composite is shown to be frequency dependent even if the thermal expansion coefficients βA and βB of both constituents are themselves frequency independent. Exact calculations for binary viscoelastic systems show that β∗ is related to constituent values βA, βB , volume fractions, and bulk moduli KA, KB , as well as...

The impact of foreign banks entry on the banking sector has been well documented in the literature. However, these studies have been confined to the conventional banking sector. On the other hand, virtually nothing has been published in respect to the impact of foreign banks entry on the Islamic banking sector. The purpose of the present paper is to provide new empirical evidence on the impact ...

Darwin chose the metaphor of 'tangled bank' to conclude the Origin of Species. Two centuries after Darwin's birth, " we are still untangling the complex ecological networks he has pondered, " writes Andy Dobson of Princeton University and colleagues, in a series of papers in the Philosophical Transactions of the Royal Society B (published online) focused on food webs. Food webs represent one of...

in this paper, single, bi-layered and three-layered tube hydroforming processes were numerically simulated using the finite element method. it was found that the final bulges heights resulted from the models were in good agreement with the experimental results. three types of modeling were kept with the same geometry, tube material and process parameters to be compared between the obtained hydr...

The Basel Committee on Banking Supervision (BCBS), in response to the recent financial crisis, has developed new stability rules aimed at preventing financial crises in the future. This paper uses the new Liquidity Ratio (LCR) and attempts to determine the impact of this ratio on the stability of the banking system. The objective of the LCR is to promote the short-term resilience of the liquidi...

Iranian banking network policymakers are focused on bank consolidation as one of the reform policies in recent years. But before merging banks, it is necessary to examine their effects. Loans are one crucial item in the bankschr('39') balance sheets that are affected by bank consolidation. In the Iranian banking network, loans are offered to various economic sectors. What is important for banki...
