We introduce two new classes of graphs which we call convex-round, respectively concave-round graphs. Convex-round (concave-round) graphs are those graphs whose vertices can be circularly enumerated so that the (closed) neighborhood of each vertex forms an interval in the enumeration. Hence the two classes transform into each other by taking complements. We show that both classes of graphs have...

The performance of different ATM switch buffer queuing schemes for round-robin and weighted round-robin didn‘t have too much difference. This paper presents the discrete-event simulation provides detailed, accurate network simulation results and it observed a wide variety of network statistics. The software simulation package, OPNET, which specializes in discrete-event simulation of communicati...

By learning about and analyzing many problems existing in the present cultivation of applied talents, this article puts forward some constructive thoughts including sticking to the “human-oriented” basis, converting the present educational ideas, conducting an all-round development, carrying out comprehensive quality education, sticking to harmonious development as demanded by economic and soci...
