User action security auditing
In a storage area network (SAN), a SAN management application provides a security audit log of security sensitive user actions performed across the storage area network. In a SAN, multiple services operate to perform requested user actions. Configurations herein substantially overcome the shortcomings of conventional SAN security event logging by providing a comprehensive security audit mechanism operable to identify and record user actions. An event normalizer disposed in each of the services identifies requested user actions, creates a uniform user action object, and sends the user action object to a coalescer operable to receive user action objects from the plurality of services in the SAN. The user action object provides a generic template responsive to each of the event normalizers in the services. The event normalizers normalize event properties and attributes concerning a user action into the generic user action object, and employs preexisting conduits for gathering and recording events.

Network attack detection using partial deterministic finite automaton pattern matching
This disclosure describes techniques for determining whether network traffic contains one or more computer security threats. In order to determine whether a symbol stream conforms to the symbol pattern, a security device stores a full deterministic finite automaton (fDFA) that accepts streams of symbols that conform to the symbol pattern. The security device also creates a partial deterministic finite automaton (pDFA) that includes nodes that correspond to the nodes in the fDFA that have the highest visitation levels. The security device processes each symbol in the symbol stream using the pDFA until a symbol causes the pDFA to transition to a failure node or to an accepting node. If the symbol causes the pDFA to transition to the failure node, the security device processes the symbol and subsequent symbols in the symbol stream using the fDFA.

Hiding an XML source in metadata to solve reference problems normally requiring multiple XML sources
The present invention provides a solution that unifies independent data sources into a single data source by hiding one of the data sources in metadata. The non-hidden source, which can reference the hidden source, can be processed by a primary XML processing agent.

If convergence does not occur, e.g., within a set time period, the state of the non-volatile storage element is sensed again, current values of the reliability metrics in the decoder are adjusted, and the decoding again attempts to converge. In another approach, the initial reliability metrics are based on multiple reads. Tables which store the reliability metrics and adjustments based on the sensed states can be prepared before decoding occurs.

A system and method identifies and masks physical sectors where the errors encountered during the defect scan exceed a predetermined level. This avoids the need to read and process all the data written to an individual sector during the initial defect scan. This method first writes a predetermined pattern such as a 2-T pattern to the magnetic media available for user data. This written pattern is then read.

Optimistic semi-static transactional memory implementations
A lock-based software transactional memory (STM) implementation may determine whether a transaction's write-set is static (e.g., known in advance not to change). If so, and if the read-set is not static, the STM implementation may execute, or attempt to execute, the transaction as a semi-static transaction. A semi-static transaction may involve obtaining, possibly after incrementing, a reference version value against which to subsequently validate that memory locations, such as read-set locations, have not been modified concurrently with the semi-static transaction. The read-set locations may be validated while locks are held for the locations to be written (e.g., the write-set locations). After committing the modifications to the write-set locations and as part of releasing the locks, versioned write-locks associated with the write-set locations may be updated to reflect the previously obtained, or newly incremented, reference version value.

Selectively monitoring loads to support transactional program execution
One embodiment of the present invention provides a system that selectively monitors load instructions to support transactional execution of a process, wherein changes made during the transactional execution are not committed to the architectural state of a processor until the transactional execution successfully completes. Upon encountering a load instruction during transactional execution of a block of instructions, the system determines whether the load instruction is a monitored load instruction or an unmonitored load instruction. If the load instruction is a monitored load instruction, the system performs the load operation, and load-marks a cache line associated with the load instruction to facilitate subsequent detection of an interfering data access to the cache line from another process. If the load instruction is an unmonitored load instruction, the system performs the load operation without load-marking the cache line.

The entity tag is sent to the client with the web page where it is stored in local cache memory. If a subsequent request for the same web page is issued from the client, the request is accompanied with the entity tag (e.g., in a header). The entity tag is decoded and analyzed by the server to determine whether the cached web page is still valid.

A cache-side prediction mechanism can predict that data requested by a cache miss can be found in another cache if the cache miss address matches an address tag of a cache line in the requesting cache and the cache line is in an invalid state. A memory-side prediction mechanism can make effective prediction based on observed memory and cache operations that are recorded in a prediction table.

Repetitive controller to compensate for odd harmonics
A repetitive controller scheme with negative feedback and feedforward introduces infinitely many poles on the imaginary axis located at the resonant peaks. The feedforward introduces zeros, which produce notches located in between two consecutive resonant peaks. The latter has the advantage of making the controllers more selective, in the sense that the original overlapping (appearing at the valleys) or interaction between consecutive resonant peaks is removed by the notches. This would allow, in principle, peaks of higher gains and slightly wider bandwidth, avoiding, at the same time, the excitation of harmonics located in between two consecutive peaks. A negative feedback compensator with feedforward is especially useful when only the compensation of odd harmonics is required, but not the even harmonics, like in many power electronic systems. In contrast, the positive feedback controller would try to reinject, and indeed amplify, any small noise, which has components on the even frequencies. The negative feedback repetitive controller includes a simple Low Pass Filter (LPF). This modification restricts the bandwidth of the controller, and at the same time reinforces the stability when the controller is inserted in a closed-loop system.

A pair of counters is established for each of one or more processors. A global counter selector determines which counter of each per-processor counter pair is a current counter. When reading a shared data element at a processor, the processor's current counter is incremented. Following counter incrementation, the processor's counter pair is tested for reversal to ensure that the incremented counter is still the current counter. If a counter reversal has occurred, such that the incremented counter is no longer current, the processor's other counter is incremented. Following referencing of the shared data element, any counter that remains incremented is decremented. Following an update to the shared data element wherein a pre-update version of the element is maintained, the global counter selector is switched to establish a new current counter of each per-processor counter pair. The non-current counter of each per-processor counter pair is tested for zero. The shared data element's pre-update version is destroyed upon the non-current counter of each per-processor counter pair being zero.

Described is an image compression technology by which a coefficient representative of a chrominance component corresponding to an (x, y) coordinate pair is coded into a symbol, along with plurality of context events associated with that symbol, to facilitate more efficient context-based arithmetic coding. For example, four context events may be generated, including one context event based on the corresponding (x, y) coefficient value in the luminance component, and three context events based on other luminance coefficients that have adjacent horizontal, vertical and diagonal relationships with the corresponding luminance component's coefficient, respectively. In one example implementation, coding the chrominance coefficient and computing the plurality of context events occurs in a zero coding pass of an entropy coder. A sign coding pass and a magnitude refinement pass may be performed to obtain further symbols for the context-based arithmetic coding.
Image analysis for image compression suitability and real-time selection
The present invention provides an analysis method that uses error metrics to determine whether an image is suitable for compression. One embodiment of the present invention can make the determination in real-time. In one embodiment, analysis methods based on four error metrics are used to determine whether a compressed image should be used. The first metric is a signal-to-noise (SNR) error metric that prevents compressed images with low SNR from being used to represent original images. Another metric is detecting the geometric correlation of pixels within individual blocks of the compressed images. The third metric is used to determine whether color mapping in the compressed images are well-mapped. A final metric is a size metric that filters images smaller than a certain size and prevents them from being compressed. As most analysis methods are integral parts of the compression process, the present invention incurs little cost collecting error metric data.

Technique for dynamically splitting MPLS TE-LSPs
A technique dynamically splits Traffic Engineering (TE) Label Switched Paths (LSPs) in a computer network. According to the novel technique, a head-end node may determine that a TE-LSP to a destination needs to be sized to a larger bandwidth (a “larger” TE-LSP) than currently available over a single path to the destination (e.g., a path that may also be required to meet other constraints, such as cost, delay, etc.). In response, the head-end node may dynamically “split” the larger TE-LSP, and create a first split TE-LSP over a best (e.g., shortest) available path (e.g., that meets other constraints). The first split TE-LSP may reserve a maximum available bandwidth for that best available path. The head-end node may then continue recursively creating subsequent split TE-LSPs for any remaining bandwidth of the larger TE-LSP over available paths until the larger TE-LSP may no longer be split (e.g., all bandwidth has been placed, configurable maximum number of splits reached, etc.). Notably, the split TE-LSPs may be “re-groomed” at a later time to recombine and reorganize the split TE-LSPs.

An ultracapacitor or hybrid capacitor includes an electrically non-conductive rigid or semi-rigid porous honeycomb separator structure having cells extending along a common direction and supporting current collector structure(s) thereon. The current collector structure may be porous and extend continuously on all inner surfaces of a cell of the honeycomb structure, or may extend along the common direction on separate portions of the inner surfaces of a cell. The material may desirably be an oxide or non-oxide ceramic, such as cordierite, silicon nitride, aluminum titanate, alumina, zircon, glass, or glass-ceramic.
Electrical isolator for capacitive device
Capacitive devices are described having electrical isolators for electrodes which possess efficient electrical contact between current collectors, electrical isolation of electrodes, and/or electrochemical stability, while minimizing the mechanical stress and strain applied to the electrodes. The capacitive devices are adaptable to a wide range of electrode diameters and electrode stack lengths.
Apparatus and method for drive controlling micro machine device
In a method for drive controlling a micro machine device including two electrodes opposing each other and a dielectric layer sandwiched therebetween, a control voltage in a rectangular waveform in which positive and negative polarities are alternately inverted is applied between the two electrodes. A current passing through the micro machine device due to the application of the control voltage are detected with respect to positive and negative sides, and parameters related to a capacitance of the micro machine device are acquired with respect to the positive and negative sides on the basis of the detected current. The control voltage is controlled so that the parameters acquired with respect to the positive and negative sides accord with each other. Thus, variation of the capacitance between the positive side and the negative side can be suppressed in switching drive of a variable capacitance device.
