Abstract: Improved document processing workflows provide a secure electronic signature framework by reducing attack vectors that could be used to gain unauthorized access to digital assets. In one embodiment an electronically signed document is removed from an electronic signature server after signed copies of the document are distributed to all signatories. The electronic signature server optionally retains an encrypted copy of the signed document, but does not retain the decryption password. This limits the amount of data retained by the electronic signature server, making it a less attractive target for hackers. However, the electronic signature server still maintains audit data that can be used to identify a signed document and validate an electronic signature. For example, a hash of the document (or other document metadata) can be used to validate the authenticity of an electronically signed document based on a logical association between an electronic signature and the signed document.

Abstract: Embodiments of the present disclosure relate to a data analysis system that may automatically generate memory-efficient clustered data structures, automatically analyze those clustered data structures, automatically tag and group those clustered data structures, and provide results of the automated analysis and grouping in an optimized way to an analyst. The automated analysis of the clustered data structures (also referred to herein as data clusters) may include an automated application of various criteria, rules, indicators, or scenarios so as to generate scores, reports, alerts, or conclusions that the analyst may quickly and efficiently use to evaluate the groups of data clusters.

Abstract: A presentation state is received from the presenting application. The presentation state may represent a current state of the local presentation. A request for the presentation state is received from the viewing application. In response to receiving the request for the presentation state, the presentation state is provided to the viewing application. A request for presentation data synchronized to the presentation state is received from the viewing application. In response to receiving the request for presentation data synchronized to the presentation state, the presentation file is transformed into the presentation data synchronized to the presentation state. The presentation data synchronized to the presentation state is provided to the viewing application. The viewing application may be operative to read the presentation data and to display a remote presentation in response to reading the presentation data.

Abstract: A simulation technique that handles accesses to a frame of instruction memory by inserting a command object between a frame proxy and a memory frame provides improved throughput in simulation environments. The instruction frame, if present, processes the access to the frame. If an instruction frame is not present for the accessed frame, the memory frame handles the request directly. The instruction frame caches fetched and decoded instructions and may be inserted at the first access to a corresponding instruction memory frame. The instruction frame can track write accesses to instruction memory so that changes to the instruction memory can be reflected in the state of the instruction frame. Additional check frames may be chained between the interface and the memory frame to handle breakpoints, instruction memory watches or other access checks on the instruction memory frame.

Abstract: A document originator establishes rules for authenticating an electronic signature. Such rules may require that any user who wishes to assent to the document terms provide biometric data in the form of an ocular image. In one implementation, such rules, as well as the document itself, are provided to a document recipient. If the document recipient assents to the document, an electronic signature is acquired from the document recipient, along with the required ocular image. The image is acquired using an infrared-enabled camera in the case of an iris image, or a retinal scanner in the case of a retina image. The acquired image can be authenticated by comparison to a trusted reference image, for example which may have been obtained from the document recipient during an initial registration process. If the comparison matches with a sufficiently high degree of confidence, then the electronic signature is considered authentic.

Abstract: In general, techniques are described to dynamically refresh a timer for a communication session provided by a bidirectional forwarding detection (BFD) protocol. The techniques potentially mitigate network load by reducing the number of BFD packets required to maintain a BFD communication session. An example network device includes a memory, programmable processor(s), a network interface, and a control unit configured to establish a BFD communication session between the network device and a peer network device that is communicatively coupled to the network device via the network interface, determine whether a packet associated with a communication session other than the BFD communication session is a relevant packet to the BFD communication session, and in response to determining that the packet is the relevant packet, refresh a timer that executes on the network device and is associated with the BFD communication session.

Abstract: In accordance with one aspect of the present technique, a method is disclosed. The method includes modifying one or more operational parameters of a gas turbine (GT) to increase an exhaust gas temperature above a standard start-up temperature. The method also includes receiving at least one of GT operational data, heat recovery steam generator (HRSG) operational data, and steam turbine (ST) operational data from a plurality of sensors. The method further includes predicting a ST roll-off time based on at least one of the GT operational data, the HRSG operational data, and the ST operational data. The method further includes modifying the one or more operational parameters of the GT to satisfy one or more ST roll-off permissives at the predicted ST roll-off time.

Abstract: A method utilizes event-driven reoptimization to reallocate one or more logical partitions within a pool of logically-partitioned data processing systems in a logically-partitioned computing environment in response to detection of a system event that is likely to increase or decrease the collective resource demands of logical partitions resident in a logically-partitioned computing environment. The reoptimization may be used to consolidate logical partitions on fewer processor nodes to improve the potential for powering down hardware resources and thereby reduce power consumption.

Abstract: The invention addresses these and other problems associated with the prior art by providing an apparatus and program product that utilize event-driven reoptimization to reallocate one or more logical partitions within a pool of logically-partitioned data processing systems in response to detection of a system event that is likely to increase or decrease the collective resource demands of logical partitions resident in a logically-partitioned computing environment. In some instances, for example, the reoptimization may be used to consolidate logical partitions on fewer processor nodes to improve the potential for powering down hardware resources and thereby reduce power consumption.

Abstract: A cooling tower simulation system may receive a measurement from a cooling tower sensor and generate a predicted Noutput of a cooling tower system based on a model of the cooling tower system. The simulation system may generate an estimated output using an extended Kalman filter with the measurement and the predicted output as inputs, wherein the estimated output represents a characteristic of the cooling tower system.

Abstract: A simulation technique that handles accesses to a frame of memory via a proxy object provides improved throughput in simulation environments. The proxy object, if present, processes the access at a head of a linked list of frames. If a check frame is not inserted in the list, the memory frame handles the request directly, but if a check frame is inserted, then the check operation is performed. The check frame can be a synchronization frame that blocks access to a memory frame while the check frame is present, or the check frame may be a breakpoint, watch or exception frame that calls a suitable handling routine. Additional check frames may be chained between the interface and the memory subsystem to handle synchronization, breakpoints, memory watches or other accesses to or information gathering associated with the memory frame.

Abstract: An electronic signature comprises an authenticated audio and/or visual recording of a spoken assent that conforms to a pre-established phrase. Alternatively, an electronic signature comprises an authenticated visual recording of a series of physical gestures that conforms to a pre-established sequence. Rules are established with respect to how the assent is to be recorded and authenticated. These rules, as well as the document itself, are provided to a document recipient. If the document recipient assents to the document, an audio and/or visual recording of the assent is generated. Location information that defines or approximates the geographical location where the document recipient recorded the assent is also optionally recorded as well. Once recorded, the assent can be authenticated using any of a variety of suitable authentication processes. An authenticated assent can be considered a legally binding electronic signature that forms a part of, or is otherwise associated with, the document.

Abstract: A mechanism is provided for handling interrupt actions for inter-thread communication. In association with a first processor thread, a thread action data structure is provided that comprises a non-blocking synchronization data structure and an internal list data structure of pending interrupts having no form of synchronization. A post of an interrupt action is received from a second processor thread to the thread action data structure associated with the first processor thread, where the interrupt action is added to the non-blocking synchronization data structure of the thread action data structure. The interrupt action is moved from the non-blocking synchronization data structure to the internal list data structure of pending interrupts for handling by the first processor thread. The internal list data structure of pending interrupts is processed to thereby handle interrupt actions moved to the internal list data structure.
