Preemptively scheduling a set of independent jobs with release time on one processor is a historical problem. In this paper, the same problem has been considered in which objective is to minimize the mean flow time. To prepare a perfect branch-and-bound, some optimality conditions have been represented and they have been compared with the optimality conditions which have been proposed before. O...

seed oils of passiflora edulis, jatropa curucas, tinospora cordifolia, sesbania grandiflora and sapindus laurifolia were investigated for their antihelmintic property against pheritima pasthuma. three concentrations (10, 50 and 100 mg/ml) of each oil were studied in the bioassay, which involved the determination of time of paralysis and time of death of the worm. sesbania grandiflora showed the...

Abstract Many problems in physics, biology, and economics depend upon the duration of time required for a diffusing particle to cross boundary. As such, calculations distribution first passage time, particular mean is an active area research relevant many disciplines. Exact results diffusion on simple geometries, such as lines, discs spheres, are well-known. In contrast, computational methods o...

Abstract: In this work, consistent estimators and simultaneous confidence bands for the derivatives of mean functions are proposed when curves are repeatedly recorded for each subject. The within-curve correlation of trajectories has been considered while the proposed novel confidence bands still enjoys semiparametric efficiency. The proposed methods lead to a straightforward extension of the t...
