The continued advances in distributed data intensive applications have formed an increasing demand for distributed commit protocols that are adaptive to large scale and dynamic nature of the applications to guarantee data consistency and integrity. Well known two-phase commit protocol and three-phase commit protocol and their variants do not provide scalability and flexibility desired for a wid...

the feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (tomac) as an extractant, was studied. the diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. the effect of initial acid concentration in t...

A scheme used in building models of three-dimensional objects through binocular and motion parallax analyses is presented. Some preliminary results in using the models for recognition are described, and a discussion of the major objectives summarizes the rationale of the work. The principal emphasis throughout the paper will be that effective vision requires flexible, domain-free, three-dimensi...
