We present a simulation-based proof method for liveness properties. Our method is based on simulation relations LV93] that relate the liveness properties of an implementation to those of the speciication. Even though reasoning about liveness is usually associated with reasoning over entire executions, variant functions, fairness etc., our method requires reasoning over individual states/transit...

extension of the building advance-sale contracts on the one hand, and inadequacy of the provisions of the civil code on protection of  building advance-buyers before making its completion, on the other, consequently causing many problems for people in the community (society), has forced the legislature to pass the building advance-sale code in 2010. the parties of these contracts are called adv...

We present a numerical scheme for the integration of the Vlasov–Maxwell system of equations for a non-relativistic plasma, in the hybrid approximation, where the Vlasov equation is solved for the ion distribution function and the electrons are treated as a fluid. In the Ohm equation for the electric field, effects of electron inertia have been retained, in order to include the small scale dynam...

We present a new numerical iterative method for computing selected eigenpairs of a right definite two-parameter eigenvalue problem. The method works even without good initial approximations and is able to tackle large problems that are too expensive for existing methods. The new method is similar to the Jacobi–Davidson method for the eigenvalue problem. In each step, we first compute Ritz pairs...

The cognitive skills required for successful academic performance includes self-regulatory functioning, an ability to enact conscious control over thoughts, feelings, and actions. The current studies examined the effects of brief periods of meditation on the academic performance of students at California State University, Northridge. Participants from four different psychology classes (three lo...

The pattern-based sequence classification system (PBSC) identifies regularly occurring patterns in collections of sequences and uses these patterns to predict meta-information. This automated system has been proven useful in identifying patterns in written language and musical notations. To illustrate the wide applicability of this approach, we classify symbolic representations of speech-accomp...

in the current age, the importance of using knowledge as a tool for creativity and innovation at national level is considerable. furthermore, it would be taken into consideration as strategic need in the competition among different countries. hence in this paper, a new knowledge strategic management framework was developed with emphasizing on knowledge based innovation, upon up studying knowled...
