The coupled aggregation and sedimentation process were studied by means of three dimension computer simulations. For this purpose, a large prism with no periodic boundary conditions for the sedimentation direction was considered. Furthermore, three equally sized and mutually excluded regions were defined inside the prism, a top, a middle and a bottom region. This allows to study the time evolut...

Today, vehicular Ad-hoc Network between automobiles has been accepted by the public, and many people are interested in exchanging information with other vehicles as well as with roadside equipment while driving. When a number of vehicles want to access to the data stored in RSU ,the priority of servicing comes into face .In this case, some  methods, such as D*S, D*S/N,  have been presented ...

The aim of this paper is to provide an analysis of the use of logically complex imperatives, in particular, imperatives of the form`Do A1 or A2' and`Do A, if B'. I argue for an analysis of imperatives in terms of Classical Logic which takes into account the innuence of background information on imperatives. I show that by doing so one can avoid some counter-intuitive results which have been ass...

The objective of Site U1395 is to characterize the sedimentation processes related to volcanic activity in the Boullante–Montserrat half graben. It is planned to drill through hemi-pelagic sediments, turbidites, and tephra retrieving a complete record of sediment down to a depth of ~244 m. Work around the Canary Islands has shown that distal volcaniclastic turbidites generated by collapse event...

Although logic is general enough to describe anything that can be implemented on a digital computer, the unreadability of predicate calculus makes it unpopular as a design language. Instead, many graphic notations have been developed, each for a narrow range of purposes. Conceptual graphs are a graphic system of logic that is as general as predicate calculus, but they are as readable as the spe...
