‎in this paper we introduce the concept of order difference interval graph $gamma_{odi}(g)$ of a group $g$‎. ‎it is a graph $gamma_{odi}(g)$ with $v(gamma_{odi}(g)) = g$ and two vertices $a$ and $b$ are adjacent in $gamma_{odi}(g)$ if and only if $o(b)-o(a) in [o(a)‎, ‎o(b)]$‎. ‎without loss of generality‎, ‎we assume that $o(a) leq o(b)$‎. ‎in this paper we obtain several properties of $gamma_...

Existing approaches to text generation fail to consider how interactions with the user may be managed within a coherent explanation or description. This paper presents an approach to generating such interactive explanations based on two levels of discourse planning content planning and dialogue planning. The system developed allows aspects of the changing context to be monitored with an explana...

Sensing and defeating microbial infections are essential to the survival of metazoan species and contingent upon the reliable detection of pathogens, which are characterized by rapid evolution and molecular heterogeneity. Multicellular species have developed two overall strategies to kill and remove parasites, to send them ‘‘floating on the Stygian river’’ (after the river Styx in Hades, the un...

We present discrete physically based methods for gen erating polygonal approximations of implicit surfaces These methods not only generate a combinatorial man ifold approximating the surface but also produce a structure that is well suited to numerical simulations in physically based modeling and animation systems

We present a method for dynamically gen­ erating Bayesian networks from knowledge bases consisting of first-order probability logic sentences. We present a subset of proba­ bility logic sufficient for representing the class of Bayesian networks with discrete-valued nodes. We impose constraints on the form of the sentences that guarantee that the knowl­ edge base contains all the probabilistic i...

Widespread interest in composting as a means of municipal sludge treatment began in the early 1970s, and has i n c r e d dramatically since that time. In 1984, the U. S. Environmental Protection Agency (EPA) initiated a technology evaluation of municipal sludge composting based on investigations at five o p erating facilities.' The facilities studied generally processed sludge reliably and effe...
