  • Publication number: 20230418575
    Abstract: An embodiment of a method can create a directed acyclic graph (DAG) from a programmer specified set of computation units to solve, in a computer program, physics based simulations of physical systems, and the DAG can be used to analyze and debug the computer program. In this method, the computer program can be created by automatically determining dependency relationships in the set of computation units and automatically schedule their execution. The method can also automatically allocate memory for the computation units.

  • Patent number: 9470232
    Abstract: A rotational speed governor for an air motor comprises a housing, a valve, a shaft, a cross-bar, a plate and a pair of weights. The housing has an air inlet and an air outlet. The valve is disposed between the air inlet and the air outlet. The shaft extends along an axis within the housing. The cross-bar is connected to the shaft. The plate intersects the shaft between the valve and the crossbar. The weights are rotatably connected to the crossbar at pivot points. Each weight comprises an arcuately profiled edge extending beyond the crossbar to engage the plate. The arcuately profiled edges are shaped to increase a moment arm on the plate as the weights pivot away from the shaft.

  • Patent number: 7585660
    Abstract: The present invention relates to a combination of a Neotyphodium species endophyte or endophyte culture in a symbiotic association with a host grass which association does not cause symptoms of toxicosis in animals through exclusion of ergovaline but, due to the inclusion of alkaloids including agroclavine, setoclavine or isosetoclavine, retains the ability to resist abiotic stresses and protect the grass from pests.

  • Publication number: 20090132319
    Abstract: A method for generating an asset loading plan is provided. The method determines at high accuracy which products and sales orders to load on which assets (e.g., machines) in order to gain a maximum profit. Specifically, the method generates an optimized loading plan of sales orders that were produced and a least opportunity cost loading plan of sales orders that were not produced. In accordance with one embodiment the method generates a chart that shows, for each asset (or a set of assets), the cash contribution per minute versus the number of cumulative production minutes. In accordance with another embodiment the method computes the marginal cash contribution to determine the additional cash contribution that could be made if additional production time is allocated to a specific asset.
