in order to study the effect of water deficit stress at different growth stages on yield and seed oil quality of rapeseed cultivars, a field experiment was conducted as split-plot in a randomized complete block design arrangement with three replications in 2009-2010 growing seasons in abarkouh in iran. four levels of irrigation were located in the main plot including, (i1) normal irrigation bas...

For most algorithms dealing with sets of points in the plane, the only relevant information carried by the input is the combinatorial configuration of the points: the orientation of each triple of points in the set (clockwise, counterclockwise, or collinear). This information is called the order type of the point set. In the dual, realizable order types and abstract order types are combinatoria...

This paper presents a computational tool based on genetic algorithm and artificial neural network for optimizing the operation of isolated diesel-photovoltaic-battery hybrid power systems using day-ahead forecasts obtained with quantile random forests. The optimization was conceived to be flexible, i.e., it can used operate multiple configurations diesel generator sets (DGS), work reduced numbe...

We consider the inverse boundary value problem in the case of discrete electrical networks containing nonlinear (non-ohmic) conductors. For a fixed nonlinear electrical network, we show that under reasonable assumptions, there are well-defined Dirichletto-Neumann and Neumann-to-Dirichlet maps relating boundary voltages and boundary currents. We also generalize work of Curtis, Morrow, and others...

The associahedron is a polytope whose graph is the graph of flips on triangulations of a convex polygon. Pseudotriangulations and multitriangulations generalize triangulations in two different ways, which have been unified by Pilaud and Pocchiola in their study of pseudoline arrangements with contacts supported by a given network. In this paper, we construct the “brick polytope” of a network, o...

Topological drawings are natural representations of graphs in the plane, where vertices are represented by points, and edges by curves connecting the points. Topological drawings of complete graphs and of complete bipartite graphs have been studied extensively in the context of crossing number problems. We consider a natural class of simple topological drawings of complete bipartite graphs, in ...

Abstract In order to meet the high demands on tolerances and surface qualities, for example in automotive lighting applications, a hybrid part composed of light metal (aluminium) an amorphous thermoplastic (polycarbonate) could be alternative established mono‐materials used today. Due lack adhesion promoter systems joining this specific material combination, micro‐form‐fitted connection by crea...

The stability of the filling roof—as an important bearing unit in stope access mining method—is great significance to guarantee safe and efficient production mine. Arrangement approach downward cemented is key factor affecting body roof. Based on a combination laboratory tests, theoretical analysis, numerical simulation, influence different arrangements roof analyzed. weak surface formed betwee...
