A load-balanced two-stage switch can eliminate the scheduler, is scalable, and provides close to 100% throughput. Its major problem is that packets can be mis-sequenced. Aim at preventing packets from being received out-of-sequence at outputs, we provide an elegant solution to the mis-sequencing problem based on a novel two-stage switch architecture with feedback. The feedback path is construct...

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

We consider graph applications of the well-known paradigm \killing two birds with one stone". In the plane, this gives rise to a stage graph as follows: vertices are the points, and fu; vg is an edge if and only if the (innnite, straight) line segment joining u to v intersects the stage. Such graphs are shown to be comparability graphs of ordered sets of dimension 2. Similar graphs can be const...
