摘要： A method for scheduling a computation for execution on a computer with a number of interconnected functional units. The computation is representable by a data-flow graph with a number of nodes connected by edge. A loop-period of the computation is calculated and the nodes are scheduled for throughput by assigning an execution cycle and a functional unit to each node of the data-flow graph. The scheduling of flexible nodes is adjusted to minimize the number of interconnections required in each execution cycle. The edges of the data-flow graph are allocated to one or more of the interconnections between functional units. The scheduling method may be used, for example, to optimize the interconnection fabric design for an ASIC or as part of a compiler for a re-configurable streaming vector processor.

摘要： A method and apparatus for allocating resources to a node in an ad-hoc communication system is provided herein. During operation, nodes of the system will receive resource allocations from their parent node. The resource allocation comprises a portion of available resources that may vary in size. Each node will determine the resource needs for its children nodes only and then dynamically assign resources to them. The resources assigned to the children nodes comprise a portion of the resources assigned to the node by its parent node. Additionally, knowledge as to how the children further allocate resources to their own children is not known by the parent, however, the children nodes must allocate a portion of their resource to their children nodes.

摘要： A system includes a first gas sensor [110] to detect a first concentration of a predetermined gas and to determine a first rate of change in the first concentration over a time interval. A second gas sensor [115] detects a second concentration of the predetermined gas and determines a second rate of change in the second concentration over the time interval. A third gas sensor [120] detects a third concentration of the predetermined gas and determines a third rate of change in the third concentration over the time interval. The first, second, and third gas sensors each have a known location. At least one processing device [510] (a) determines respective distances between a gas leak location and the respective locations of the gas sensors based on the detected rates of change, and (b) calculates a location of the gas leak based on a triangulation of the first distance, the second distance, and the third distance.
