For the past three years, TRW has been developing a text analysis tool called DEFT-Data Extraction from Text . Based on the Fast Data Finder (I'D I .), l)EF'l' processes larg e volumes of text at very high speeds, identifying patterns which serve as indicator s for the presence of relevant objects, relationships, or concepts in the data . These indicators are processed by a series of system-sup...

GMRES is an iterative method that provides better solutions when dealing with larg linear systems of equations with unsymmetric coefficient matrix. By shifting the Arnoldi process to begin with Ar0 instead of r0, simpler GMRES implementation, proposed by Walker and Zhou in 1994, is obtained that in this method, an upper triangular problem is solved instead of hessenberg least square problem. Th...

Optimal structural design under creep conditions, initiated over 20 years ago, brings a fairly larg~ variety of problems, interesting both from theoretical and engineering point of view. Existence of the time factor leads to optimization for a prescribed lifetime and the number of independent variables in governing equations increases by one. Practical importance is connected with design of met...

System Metaphor is one of the key practices of Extreme Programming (XP). Unfortunately, the System Metaphor practice is poorly understood, and is the practice XP teams most commonly choose to ignore. In this paper, we provide a small collection of patterns that teams can use to develop metaphors for their systems, and for evaluating system metaphors. We hope these patterns will encourage Extrem...
