Recovery from failures within data processing systems

Provided are methods, data processing systems, recovery components and computer programs for recovering from storage failures affecting data repositories. At least a part of the recovery processing is performed while the data repositories are able to receive new data and to allow retrieval of such new data. Although new data items may be received into the repository and retrieved therefrom during recovery processing, updates to the data repository which were performed before the failure and which are then restored to the repository by the recovery processing are restored within a recovery unit of work and are inaccessible to processes other than the recovery process until successful completion of the recovery unit of work. The recovery processing ensures that the recovered repository is consistent with the state of the repository at the time of the failure, but is available for addition and retrieval of new data items before completion of the recovery processing.

System, method and article of manufacture for Z-value and stencil culling prior to rendering in a computer graphics processing pipeline

A system, method and article of manufacture are provided for early Z-value based culling prior to pixel rendering in a graphics pipeline. In initial stages of processing, Z-value culling is performed on at least one pixel. Thereafter, the pixel is conditionally rendered. Whether the pixel is rendered or not is conditioned on results of the Z-value culling. By culling, or removing, the pixels that do not meet certain criteria prior to rendering, much processing is avoided in the rendering portion of the graphics pipeline.

A wind turbine (1) is provided, having a wind turbine tower (2) and at least one rotatable blade (5), and further comprising a system for measuring rotor blade vibration of said wind turbine. The system comprises at least one Doppler radar unit (7) operatively configured to emit and receive radar signals, the radar unit being mounted on the wind turbine tower at a position above the lowest position of the at least one blade, the radar unit being positioned so as to measure reflections of an emitted radar signal from the turbine blade. A processing unit is configured to receive measurement data from the radar unit and to determine, by analysis of Doppler shift in received radar signals relative to transmitted signals due to movement of the blade towards or away from the turbine tower, the velocity of the blade in the direction towards or away from the turbine tower. Using a radar unit to measure blade velocity allows a determination to be made of the vibrations occurring in the blade without needing an internal sensor in the blade. This reduces manufacturing and maintenance costs of the blades since sensors in the blades will not need to be replaced, and sensors positioned on the tower are easier to replace in the field.

Auto-committing files to immutable status based on a change log of file system activity

A system and method are provided for auto-committing files of a storage system to immutable status based on a change log of file system activity. The system is configured for producing and analyzing the change log. Producing the change log involves generating change log entries associated with changes made to files of the storage system and organizing the change log entries from the oldest to newest entries. Analyzing the change log involves processing the change log beginning with the oldest entry to determine whether any entries have met the auto-commit time period, and if so, to set the files associated with such entries to immutable status. If a change log entry is found not to have met the auto-commit time period, a resting time period is determined based on the oldest change log entry, and processing of the change log proceeds after expiration of the resting time period.

The one or more initial quality parameters are based on the pilot signal and are associated with a first symbol of the quick paging signal. A third mechanism ascertains whether a second symbol of the quick paging channel signal or the subsequent paging channel should be processed based on the one or more initial quality parameters and provides a first indication in response thereto. A fourth mechanism determines if the subsequent paging channel should be processed based on a second quality parameter (Epilot2 / Îo2) and a combined decision metric (demodulation symbol (D)) associated with both the first symbol and the second symbol when the first indication indicates that the second symbol should be processed. The fourth mechanism provides a second indication response thereto.

Sequential combined QPCH demodulation

A system determines if a primary paging channel should be received based on an examination of a quick paging channel. A first QPCH symbol is examined (102) and the normalized pilot energy is determined (104). If the normalized pilot energy is above a first threshold (106), the symbol is demodulated and the QPCH-symbol-to-pilot-energy ratio is determined (110) and compared against another threshold (114). If the normalized pilot energy is below the first threshold, the system proceeds to the second QPCH symbol immediately. Based on the two comparisons, a second QPCH signal is examined (108) or the system sleeps (116). If the second signal is examined, and if its normalized pilot energy is high enough, it also is demodulated and the ratio of the sum-of-the-combined-QPCH-symbols to the sum-of-the-combined-pilot-energies is determined (122). If this ratio exceeds a threshold (124), the primary paging channel is processed (120); otherwise the system sleeps (116).

Data stream comprising RTP packets, and method and device for encoding/decoding such data stream

In the case of packet loss during transmission over an error-prone transmission channel, some decoders may perform error concealment. In real-time systems, application decoders must handle the data loss alone and find out which data are missing. A special syntax within a packet-based framework is provided which is based on identifying and indicating the relationship between RTP packets and the application layer data they carry, before the packets are fed to the multi-layer application decoder. This helps the decoder to employ proper error concealment techniques in time, and prevents unnecessary processing in the decoder. A data stream comprises RTP packets containing application data of a multi-layer application, wherein an RTP packet (p2) contains two kinds of application layer information (NBf, NBn): one relating to the next RTP packet (p3), and one relating to the previous RTP packet (p1). In case of packet loss, the decoder can immediately determine the amount and type (VCLx) of missing data.

Responsive to the retrieve request, the multimedia message is delivered to the user agent so that the streamable media component is represented with a descriptor pointing to a location from which the SDD can be obtained. The SDD is generated before or after the user agent requests for retrieval of the multimedia message but not necessarily by the time the user agent is notified for the availability of the multimedia message.
