摘要:
A stream processing execution engine evaluates development-time performance characteristic estimates in combination with run-time parameters to schedule execution of stream processing software components in a stack of a stream processing application that satisfy a defined performance criterion in a heterogeneous hardware device. A stream processing application includes a stack of interdependent stream processing software components. A stream processing execution engine evaluates one or more performance characteristics of multiple computational resources in the heterogeneous hardware device. Each performance characteristic is associated with performance of a computational resource in executing a computational-resource-dependent instance of a stream processing software component. The stream processing execution engine schedules within the run-time environment a computational resource on which to execute a computational-resource-dependent instance of one of the stream processing software components. The computational-resource-dependent instance is targeted for execution on the computational resource that satisfies a performance policy attributed to the stream processing software component.

Embodiments related to automatically adjusting wireless network settings based upon utilization of a wireless network link by applications are disclosed. For example, one disclosed embodiment provides a method of adjusting a wireless networking setting for a wireless network link. The method includes monitoring data flow through a network interface controller to collect, for each of one or more applications running on the computing device and communicating over the wireless network link, flow performance data comprising information regarding an amount of data flow arising from the application. The method also includes monitoring link data comprising information regarding data being sent and received over the wireless network link, and based upon the flow performance data and the link data, controlling a network interface controller to adjust the wireless networking parameter to change a configuration of the network link.

A torsion axle arrangement is provided wherein the spindle is mounted to the suspension link by a keyed connection facilitated with a selectively orientable disc then fixed to the suspension link according to a given application. That connection is maintained by a bolt passing through the suspension link and engaging a mating groove in the spindle. The bolt is anchored within the suspension link by a threaded connection internal to the suspension link. The shape of the key can be selected as desired for immediate source identification.

A multi-axle leaf spring suspension having a compliant equalizer. The leaf springs are mounted one behind the other on each side of the vehicle. Adjacent ends of the leaf springs are pivotally attached to the compliant equalizer. The compliant equalizer is pivotally mounted to a vehicle frame. The compliant equalizer comprises a pair of arms that are pivotally connected to each other in a scissor-like fashion. One end of each arm is pivotally connected to the end of a leaf spring. The other end of each arm is cooperatively arranged to contain and compress a spring member between them. The compliant equalizer reduces the magnitude of shocks that would be other wise transmitted to the suspension and frame by absorbing them through compression of the spring member.

Methods and systems for providing support for large data sets are provided. Example embodiments provide a Big Data Object Library “BDOL,” which defines data structures and routines for handling big data objects using out of memory techniques. In one embodiment, the BDOL defines a bdFrame object which stores the data in binary form in a cache on an external storage medium, such as a file on a disk. The example BDOL provides support for user defined block processing a bdFrames using a pipeline engine. Also, the BDOL provides for Trellis plots, and other charts, of big data objects using hexagonal binning. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.
摘要:
A method is disclosed for managing the sale of a plurality of items from a plurality of corresponding suppliers to at least one buyer, wherein the one buyer determines a description of the item to be purchased. The method enables each of the plurality of suppliers to store at least one catalogue of its items in a database and responding to a search request of the one buyer to identify any item in the catalogues stored in the database with a description that matches the item description of the buyer.
