In this article, an optimal control problem subject to a semilinear elliptic equation and mixed control-state constraints is investigated. The problem data depends on certain parameters. Under an assumption of seperation of the active sets and a second-order sufficient optimality condition, Bouliganddifferentiability (B-differentiability) of the solutions with respect to the parameter is establ...

Complexity classes with nite acceptance types are the classes obtained by nonde-terministic machines, if the global acceptance condition is of the form: the number of accepting computation paths is in the set A, for some xed nite set A. We study the relationships between such classes, exhibiting conditions, under which one class is contained in another one relative to all oracles, or conversely...

The radio channel assignment problem can be cast as a graph coloring problem. Vertices correspond to transmitter locations and their labels (colors) to radio channels. The assignment of frequencies to each transmitter (vertex) must avoid interference which depends on the seperation each pair of vertices has. Two levels of interference are assumed in the problem we are concerned. Based on this c...

A stability indicating reversed phase ultra performance liquid chromatography (RP-UPLC) method was developed for simultaneous determination of ambroxol hydrochloride (AMB), cetirizine hydrochloride (CTZ), methylparaben (MP) and propylparaben (PP) in liquid pharmaceutical formulation. The desired chromatographic separation was achieved on an Agilent Eclipse plus C18, 1.8 μm (50 × 2.1 mm) column ...

understanding of the runoff generation processes is important in understanding the magnitude and dynamics ofgroundwater discharge. however, these processes continue to be difficult to quantify and conceptualize. in this study,two digital filter based separation modules, the recursive filtering method (rdf) and a generalization of therecursive digital filter (grdf) were1991–2002 in the hableh ro...

A simple, rapid, selective, sensitive, linear, precise and accurate RP-HPLC method was developed and validated for the determination of raltegravir in bulk and in tablet dosage forms. Seperation of the drug was achieved on a reverse phase Symmetry C8 column (150mmx4.6mm I.D., 5 m particle size) at ambient temperature using a mobile phase consisting of phosphate buffer pH 2.5 and acetonitrile i...
