A median (antimedian) of a profile of vertices on a graph G is a vertex that minimizes (maximizes) the sum of the distances to the elements in the profile. The median (antimedian) function has as output the set of medians (antimedians) of a profile. It is one of the basic models for the location of a desirable (obnoxious) facility in a network. The median function is well studied. For instance ...

In this paper, we provide efficient algorithms for solving the weighted center problems in a cactus graph. In particular, an O(n log n) time algorithm is proposed that finds the weighted 1-center in a cactus graph, where n is the number of vertices in the graph. For the weighted 2-center problem, an O(n log n) time algorithm is devised for its continuous version and showed that its discrete ver...

Vector control is the foremost step to diminish the mosquito borne diseases as the proper vaccinations are yet to develop against those obnoxious diseases. After many resistant cases, it is important to develop other sources of eco-friendly insecticides. The present piece of study was designed to evaluate the mosquito larvicidal efficacy of Operculina turpethum against malarial vector Anopheles...

• Plants are integral parts of nature and constitute the major portion of animals’ ration in the form of green and dry fodders. • Some plants are very obnoxious and produce toxicity amongst livestock. Lantana is one of them. • There are about 40 species of the genus Lantana. The important species include L. camara, L. indica, L. crenulata and L. trifolia. • Amongst various species L. camara var...

A median (antimedian) of a profile of vertices on a graph G is a vertex that minimizes (maximizes) the remoteness value, that is, the sum of the distances to the elements in the profile. The median (or antimedian) function has as output the set of medians (antimedians) of a profile. It is one of the basic models for the location of a desirable (or obnoxious) facility in a network. The median fu...

in this study, we investigate the further properties of quasi irresolute topological groupsdened in [20]. we show that if a group homomorphism f between quasi irresolute topologicalgroups is irresolute at eg, then f is irresolute on g. later we prove that in a semi-connectedquasi irresolute topological group (g; ; ), if v is any symmetric semi-open neighborhood ofeg, then g is generated by v...

the polynomial interpolation in one dimensional space r is an important method to approximate the functions. the lagrange and newton methods are two well known types of interpolations. in this work, we describe the semi inherited interpolation for approximating the values of a function. in this case, the interpolation matrix has the semi inherited lu factorization.
