Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3,   Pages 312-315 doi: 10.1007/s11709-009-0037-y

Abstract: The movement of bottom high-sediment sea water under water waves, especially that of the high-sedimentthe movement of the interfaces of air-water and water-sediment water was tracked by the volume of fluidThe velocity field of sediment water was simulated by considering the effect of water waves.The results show that the movement of sediment water is very different from that of sea water, whichwater-sediment water interface movement on the air-water interface is not obvious.

A New Sufficient Conditions and Hamiltonian graphs

Zhao Kewen

Strategic Study of CAE 2003, Volume 5, Issue 11,   Pages 61-64

Abstract:

Let G be a simple graph, δ and a be minimum degree and independence number of G, respectively, Faudree et al showed, in 1991, the Hamiltonian result with condition | N(x)∪ N(y) | ≥n-8. In 1993, Chen further considered the Hamiltonian with condition max |d{x) , d(y)| n/2 for each pair of non-adjacent vertices x , y with 1≤|N(x)∩NV(y)|≤a-l. In this paper a sufficient condition for a graph to be Hamiltonian graph is shown and the following result is obtained ： let G be a 2-connected graph of order n , if| N(x) U N(y) |≥ n-δ-1 for each pair of non-adjacent vertices x, y with 1≤ | N(x)∩ N(y) |α-1, then G is Hamiltonian or G∈{K(n-1)/2, (n + 1)/2, K2* V3K(n-2)/3}，This result generalizes some results in Hamiltonian graphs .
