Since 1993, Los Alamos National Laboratory has been developing World Wide Web (WWW) applications to facilitate access to vast quantities of information critical to the successful operation of a nuclear weapons facility. Explorer is a web-based tool that integratesfulltext search and retrieval technology, custom user inte$aces, user-friendly navigation tools, extremely large document collections...

Experiments have been conducted to study the effect of addition of fly ash, copper slag, and steel and polypropylene fibres on compressive strength of concrete and to determine the hierarchical order of influence of the mix variables in affecting the strength using cluster analysis experimentally. While fly ash and copper slag are used for partial replacement of cement and fine aggregate, respe...

AIM To assess the adequacy of the types and quantities of antidotes, antivenoms and antitoxins held by New Zealand hospital pharmacies. METHODS A list of 61 antidotes, antivenoms, antitoxins and their various forms was developed following literature review and consideration of national pharmaceutical listings. An Internet-accessible survey was then developed, validated and, during the period ...

The present study investigates novelties brought into the classic Biot’s theory of propagation of elastic waves in a fluid-saturated porous solid by inclusion of non-Newtonian effects that are important, for example, for hydrocarbons. Based on our previous results (Tsiklauri and Beresnev, 2001), we investigated the propagation of rotational and dilatational elastic waves by calculating their ph...

Information theory for non-additive measures has always attracted considerable attention. This effort resulted, among others, in defining information measures for Dempster-Shafer (D-S) theory. In the paper, the properties of information quantities called the aggregate uncertainty (AU) and the nonspecificity are discussed within the framework of possibility theory that may be viewed as a special...

It is shown that probabilistic beliefs and est imation of quanti t ies give rise to the same model, that of a type spacer and can be viewed as the two sides of the same coin. We s tudy the axiom of correct est imation, which s ta tes tha t an agent 's est imation of his own est imation is correct, showing it to be weaker than the introspection axiom, according to which an agent is certain of hi...
