Many knowledge-based systems feature general machinery that operates on externally supplied information, These systems must solve the acquisition problem: how to represent the external knowledge, determine if it is adequate, and incorporate it into the knowledge base. As a mediator between users and interactive services, the Consul system must understand the intent and behavior of programs that...

We describe Builder, a language and environment for interactive specification and simulation of business-oriented models. The Builder language uses an object-oriented declarative approach, combining a visual specification of the model structure (the business entities) with a declarative specification of model behaviour. The Builder environment supports exploratory development of models, with a ...

We study on-line version of size-Ramsey numbers of graphs defined via a game played between Builder and Painter: in one round Builder joins two vertices by an edge and Painter paints it red or blue. The goal of Builder is to force Painter to create a monochromatic copy of a fixed graph H in as few rounds as possible. The minimum number of rounds (assuming both players play perfectly) is the on-...

Also, rights obligations investor builder, performance services works, including contract for construction work, objects contract, deadline completion object, subject responsibility lender borrower. The builder is liable accidental loss or damage, creditor causing harm to third parties, transfer his ...

Virtual reality provides a powerful way to visualize the three-dimensional, atomic-level structures of molecules and materials. We present new virtual software for molecular modeling testing use in organic chemistry education. The open-source software, named VRChem, was developed primarily building, visualizing manipulating using head-mounted system. design goal VRChem create an easy-to-use ent...

Many scheduling dispatching rules are intuitive and processes which people utilize in every day life. As an example, when faced with a variety of tasks due at different times one often implements the earliest due date scheduling rule: the next task worked on is the one with the earliest due date. Other common scheduling dispatching rules have the nice property of being easy to understand, there...

Let M= ( A B C 0 ) be a complex square matrix where A is square. When BCB = 0, rank(BC) = rank(B) and the group inverse of ( BAB 0 CB 0 ) exists, the group inverse of M exists if and only if rank(BC + A ( BAB ) π BA) = rank(B). In this case, a representation of M in terms of the group inverse and Moore-Penrose inverse of its subblocks is given. Let A be a real matrix. The sign pattern of A is a...

The Ramsey game we consider in this paper is played on an unbounded set of vertices by two players, called Builder and Painter. In one move Builder introduces a new edge and Painter paints it red or blue. The goal of Builder is to force Painter to create a monochromatic copy of a fixed target graph H, keeping the constructed graph in a prescribed class G. The main problem is to recognize the wi...

To participate in musical improvisations, an interacting system must both generate appropriate musical materials and express those materials appropriately in collaboration with other performers. We have used results from the study of conversation and discourse to identify the major components for a theory of improvisation—listening, composing, and realizing. Our goal is a framework based on a m...
