A mechanical model of a digital balancing system is constructed and its stability analysis is presented. This model considers experimental problems like backlash and sampling delay. The conditions of existence of stable stationary and periodic solutions are determined for the case of the system without delay. Phase diagrams and bifurcation diagrams are revealed after simulations and bifurcation...

This paper describes a technique for obtaining maximumthroughput schedules for iterative data-flow graphs, given a limited set of resources. The method is based on the use of the scheduling-range chart, where the scheduling window of each operation is displayed. This scheduling window, or scheduling range, is relative to a reference operation, and can be finite or infinite. The information in t...

Abstract Reciprocity—the mutual provisioning of support/goods—is a pervasive feature social life. Directed networks provide way to examine the structure reciprocity in community. However, measuring involves assumptions about what relationships matter and how elicit them, which may impact observed reciprocity. In particular, practice aggregating multiple sources data on same relationship (e.g., ...
