We present a transaction commit protocol “Transaction Commit On Timeout (TCOT)” based on a “timeout” approach for Mobile Database Systems (MDS), which can be universally used to reach a final transaction termination decision (e.g., commit, abort, etc.) in any message oriented system. Particularly suited for a wireless environment, a timeout mechanism is the only way to minimize the impact of th...

This research in progress proposes an approach to technology adoption that focuses on technology as sign and symbol. Drawing from social theory and consumer behavior literature, we initiate a qualitative study that uses both subject narrative and a visual interpretation of the subject (through photographs of the subject and their technology) to identify how each subject’s social environment bui...

in this study, gas evolution in a vertical electrochemical cell is investigated numerically with a modified two-fluid model. the mathematical model involves solution of separate transport equation for the gas and liquid phases with an allowance to inter-phase transfer of mass and momentum. the governing equations are discreted via the finite volume technique and then are solved by the simple al...

We construct in this paper two classes, based on stabilization and convex splitting, of decoupled, unconditionally energy stable schemes for Cahn-Hilliard phase-field models of two-phase incompressible flows. At each time step, these schemes require solving only a sequence of elliptic equations, including a pressure Poisson equation. Furthermore, all these elliptic equations are linear for the ...

The following ropics related to the representation of two-phase (i.e. , gas and brine) flow in the licinity of the reposito~ in the 1996 performance assessment (P.4) for the Y$’aste Isolation Pilot Plant (IVIPP) are discussed: (i) system of nordin-partial differential equations used to model two-phase flow, (ii) incorporation of repository . shafis imo model (iii) creep closure of repository.
