Abstract: An operating system directed to using special properties of a common inter-process communications mechanism (IPC), namely UNIX domain socket-pairs or stream-pipes alternatively as a storage medium for file-descriptors of UNIX processes. When a file-descriptor is written into a socket-pair, and closed in the UNIX process, the file remains open, but occupies no space in the process' file-table. The file-descriptor may later be read out of the socket-pair to reestablish it in the file-table, and access it. This property is implemented in an IPC mechanism of UNIX operating system whereby a process such as a dispatcher may manage more connections and processes than its file-table size allow. This provides scalability improvements of the UNIX operating system.

The third event is the basic software verification completed event. The fourth stage is the basic hardware services verified phase. The fourth event is the basic hardware verification completed event. The fifth stage is the extended hardware services verified phase. The fifth event is the full integration of disturbed entity event.

Abstract: A system and method for estimating agricultural parameters for growing crops is well suited for promoting efficient utilization of agricultural inputs (e.g., water consumption). Sensors collect data via one or more vehicles equipped with location-determining receivers. A transmitter transmits the collected environmental data to a data processing system. The data processing system applies the collected environmental data to an agronomic model for determining an agricultural management parameter. A prescription is made available for application of an agricultural input (e.g., water) to a crop in a particular location consistent with the collected environmental data and the agronomic model.

Abstract: A computer implemented method and apparatus for identifying component breakdown of noise sources. Noise data is received for a noise source from an array of sound sensors. Measurement points of interest, candidate sound source points along an axis, and array aperture angles are identified. Sets of first and second bounding traces are identified from ray traces extending from the candidate noise source points towards the measurement points of interest using the array aperture angles. The bounding ray traces are rotated around the axis to form sets of first and second surfaces. Sets of first and second curves are identified from an intersection of the sets of first and second surfaces with the ground plane. Sound sensors are selected from the array using the curves to form subarrays. The component breakdown of noise generated by the noise source is identified using noise data from sound sensors in the subarrays.

Abstract: A method, apparatus, and computer usable program code for presenting terrain elevation information on a vehicle display. In one advantageous embodiment, a swath representing an area ahead of the vehicle is identified, wherein the swath has a length and a width. A two dimensional elevation view is presented on the vehicle display, wherein a vertical axis of the two dimensional elevation view represents a highest elevation along a width of a swath for a particular point along the length of the swath. The width of the swath is updated in response to vehicle movement to form an updated swath width. The two dimensional elevation view is updated using the updated swath width.

Abstract: A computer implemented method, data processing system, and computer usable code are provided for burn-in testing of a multiprocessor. A process identifies a power management data set for a plurality of processor cores associated with the multiprocessor. The process selects one or more of the plurality of processor cores to form a selected set of processor cores based upon the power management data set. The process initiates a burn-in test across the selected set of processor cores. In response to a determination that all processor cores in the plurality of processor cores have not been selected, the process repeats the above selecting and initiating steps until all the processor cores have been selected.

Abstract: A system for utilizing the processing power of a mobile device. It is determined whether an energy source within the mobile device is recharging. In response to determining that the energy source within the mobile device is recharging, it is determined whether the mobile device is sending or receiving transmissions. In response to determining that the mobile device is not sending or receiving transmissions, a task is requested from a server via a network. In response to receiving the task from the server, the task is routed to a processor of the mobile device to process the task and return a task result. Then, the task result is sent to the server via the network.

Abstract: An embodiment provides a computer implemented method for social profile assessment. The computer implemented method receives a request from a first user for an assessment, and sends questionnaires to a set of assessors for the first user. Upon receiving questionnaires from the set of assessors to form completed questionnaires, the computer implemented method generates an unadjusted social style assessment for the first user. Upon receiving a request from a second user for the social style assessment of the first user, the computer implemented method determines whether there are common assessors between the first user and the second user, and responsive to a determination that there are common assessors between the first user and the second user, generates an adjusted social style assessment for the first user, and returns the adjusted social style assessment for the first user to the second user.

In an illustrative method, a first cohort is generated from the plurality of data. An optimal control cohort is generated from the plurality of data. Generating is performed based on the first cohort and at least one constraint, and a mathematical process is used to derive the optimal control cohort. A first inference is generated based on a comparison of the first cohort to the optimal control cohort, wherein the first inference is absent from the database. In an illustrative example, the first inference is stored.

Abstract: A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided. The memory management mechanism permits both buffered sending and receiving of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism permits grouping of DMA buffers that can be shared among specified connections based on any number of attributes. The memory management mechanism further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system in bulk, and expedited transfer of data to the host system.

Abstract: There is provided a method for executing a program comprising a function call and one or more subsequent instructions. The method comprises processing, on a first thread, a function defined by the function call, the function having one or more programmer predefined typical return values. For each predefined return value, the one or more subsequent instructions are pre-processed on an additional thread assuming that the function returned that pre-defined return value. In this way the processor, on completion of processing said function is able to make use of the pre-processing completed by the additional thread which used the actual return value.
