in this research, the effect of different concentrations of chitosan (with low molecular weight) on in vitro proliferation of grape cultivar, ’bidaneh ghermez‘, was evaluated. 30 days after establishment, elongated shoots were cultured on the half strength murashige and skoog medium supplemented with 0.5 mg/l bap, 0.1 mg/l iba and different chitosan concentrations (0, 10, 20, 40 and 80 mg/l). t...

Description logics are used to solve a wide variety of problems with configuration applications being some of the largest and longest-lived. There is concrete, commercial evidence that shows that description logic-based configurators have been successfully fielded for over a decade. Additionally, it appears that configuration applications have a number of characteristics that make them well-sui...

In many industrial and non-industrial applications, it is necessary to identify the largest inscribed rectangle in a certain shape. The problem is studied for convex and non-convex polygons. Another criterion is the direction of the rectangle: axis aligned or general. In this paper a heuristic algorithm is presented for finding the largest axis aligned inscribed rectangle in a general polygon. ...
