Abstract: An internal cooling grid is mounted internal to a facility, such as a data center, and includes a plurality of fluid transport elements arranged in a grid pattern with nodes at intersections of the grid pattern. Supply and return manifolds included in the nodes receive (and return) cooling fluid from/to more than two transport elements. Thus, a failure of one or more transport elements does not prevent a node from being supplied cooling fluid from at least a first transport element and a second transport element. In some embodiments, the cooling grid may be operated at a pressure less than one atmosphere, such that any leaks that occur cause air to leak into the cooling grid instead of cooling fluid leaking out of the cooling grid.

Abstract: A monitoring system may receive data indicating work performed by a set of computing devices during a given period of time and may receive data indicating an amount of power consumed by the set of computing devices and support systems that support the set of computing devices during the given period of time. The monitoring system may normalize the amounts of work performed by different types of computing devices in the set and determine an aggregate amount of work performed by the set. The monitoring system may also determine an aggregate amount of electrical power consumed by the set of computing devices and support system that support the set of computing devices during the given period of time. A monitoring system may use the aggregate amount of work performed and aggregate amount of power consumed during the given period of time to determine a performance index efficiency for the set.

Abstract: The invention relates to off-center detector 3D X-ray or proton radiography reconstruction. Redundancy weighting with a steep weighting function around the iso-axis typically leads to artifacts in the reconstruction, for example, if inconsistencies between two nominal redundant projections occur, e.g. due to slightly incorrect detector calibration or scatter correction, etc. With the present invention, an approach is presented for overcoming or mitigating these problems.

Abstract: The present disclosure is directed to systems and methods for protecting software application information that is passed between a caller of an API and the logic contained within the API by using a Secure Calling Convention (SCC). The SCC involves performing a cryptographic operation on the information such that the true nature of the information is obfuscated. The SCC prevents a hacker from using the information to reverse-engineer the software application to behave as desired.

Abstract: A two-step gasification process and apparatus for the conversion of solid or liquid organic waste into clean fuel, suitable for use in a gas engine or a gas burner, is described. The waste is fed initially into a primary gasifier, which is a graphite arc furnace. Within the primary gasifier, the organic components of the waste are mixed with a predetermined amount of air, oxygen or steam, and converted into volatiles and soot. The volatiles consist mainly of carbon monoxide and hydrogen, and may include a variety of other hydrocarbons and some fly ash. The gas exiting the primary gasifier first passes through a hot cyclone, where some of the soot and most of the fly ash is collected and returned to the primary gasifier.
