The long-term goals of this project are to first develop a three-dimensional time-evolving non-linear numerical model of the mesoscale ionosphere, second to couple the mesoscale model to a mesoscale data assimilative analysis, third to use the new data-assimilative mesoscale model to investigate ionospheric structure and plasma instabilities, and fourth to apply the data-assimilative mesoscale ...

A program Q simulates a program P in lock-step under a given representation of states of P as states of Q if there is a constant c such that if P transforms a state A to a state A in time then Q transforms (A) into (A) in time c . (Cf. the related notions of real-time computation and simulation [R,S].) The constant c is the lag factor of the simulation. We speak about time rather than the numbe...

Automated theorem proving is a method to establish or disprove logical theorems. While these can be theorems in the classical mathematical sense, we are more concerned with logical encodings of properties of algorithms, hardware and software. Especially in the area of hardware verification, propositional logic is used widely in industry. Satisfiability Module Theories (SMT) is a set of logics w...

a procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. the method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. the main advantage of this systematic procedure with respect to other reported procedures is using non-equilibrium s...
