If you are an ultra-rich oil baron for whom petroleum is the basis of all your wealth and poweryou are going to fight the solar power industry like you were a cornered wolverine.
Although they have been shown to be useful, people find them difficult to query in flexible ways. This limits the reusability of the knowledge they contain. Databases and noninteractive rule systems such as logic programs, on the other hand, are queryable but they do not offer an interview capability.
This thesis is the first investigation that we know of into query-processing for interactive expert systems. In our query paradigm, the user describes a hypothetical condition and then the system reports which of its conclusions are reachable, and which are inevitable, under that condition.
For instance, if the input value for bloodSugar exceeds units, is the conclusion diabetes then inevitable? Reachability problems have been studied in other settings, e. We first give a theoretical framework for query-processing that covers a wide class of interactive expert systems.
Then we present a query algorithm for a specific language of expert systems. This language is a restriction of production systems to an acyclic form that generalizes decision trees and classical spreadsheets. The algorithm effects a reduction from the reachability and inevitability queries into datalog rules with constraints.
When preconditions are conjunctive, the data complexity is tractable. Next, we optimize for queries to production systems that contain regions which are decision trees.
When general-purpose datalog methods are applied to the rules that result from our queries, the number of constraints that must be solved is O n 2where n is the size of the trees.
We lower the complexity to O n.
Finally, we have built a query tool for a useful subset of the acyclic production systems. To our knowledge, these are the first interactive expert systems that can be queried about the reachability and inevitability of their conclusions.Kune is based on Apache Wave and is a free/open source distributed social network focused on collaboration rather than just on We never know when we’re going to die or what circumstances are going to lead to our death.
Classical fluid dynamics and the Navier-Stokes Equation were extraordinarily successful in obtaining quantitative.
Targeting spam control on middleboxes: Spam detection based on layer-3 e-mail content classification including packet re-ordering, fragmentation, overlapped bytes, and different packet sizes. However, data collected through user feedback and spam honeypots could be used for training.
Furthermore, spam, when seen on network nodes, shows. We also formalize the notion of secure remote execution and present machine-checked proofs showing that the TAP satisfies the three key security properties that entail secure remote execution: integrity, confidentiality and secure measurement.

Recent developments during the implementation of the Unified Solids library Example G01 shows how to write a simple application for importing and exporting GDML files, providing a variety of samples for different kinds of solids, volumes, material descriptions, integration of optical surface parameters, and so on.
Recent developments in. The point is, if you the science fiction writer postulate lots of technological advances in your novels, you must at least pay lip service to the sad fact that it will make a sizable segment of your society very angry.
