A technique for managing the session state of a web application during transaction processing. When a message is exchanged between a web client and a web server, such as a web client request or a web server response, session information therein is stored on behalf of the client. Following an interruption in session state, the session state may be recreated by using the stored session information.

System and method for modeling a nonlinear process. A combined model for predictive optimization or control of a nonlinear process includes a nonlinear approximator, coupled to a parameterized dynamic or static model, operable to model the nonlinear process. The nonlinear approximator receives process inputs, and generates parameters for the parameterized dynamic model. The parameterized dynamic model receives the parameters and process inputs, and generates predicted process outputs based on the parameters and process inputs, where the predicted process outputs are useable to analyze and/or control the nonlinear process. The combined model may be trained in an integrated manner, e.g., substantially concurrently, by identifying process inputs and outputs (I/O), collecting data for process I/O, determining constraints on model behavior from prior knowledge, formulating an optimization problem, executing an optimization algorithm to determine model parameters subject to the determined constraints, and verifying the compliance of the model with the constraints.

A system enables indirect determination of a position vector (V_R) of a point position (P). The system uses two fixed trackers (10 and 10′) whose absolute positions are known. A movable measuring device (20) provides a rigid rod (25) supporting a pair of reflectors (30 and 30′) which are mounted at fixed positions. A reference point (R) is mounted at a further fixed position on the rod (25) and is on a straight line (L) through the reflectors (30 and 30′). Light beams from the trackers (10 and 10′) acquire the reflectors (30 and 30′) so that when the reference point (R) is positioned at the point position (P), the position vector (V_R) of point position (P) is determinate by vector addition.

The subject matter herein generally relates to transcoding content, typically audio/video files though not limited to such, from one version to another in preparation for online streaming or other delivery to end users. Such transcoding may involve converting from one format to another (e.g., changing codecs or container formats), or creating multiple versions of an original source file in different bitrates, frame-sizes, or otherwise, to support distribution to a wide array of devices and to utilize performance-enhancing technologies like adaptive bitrate streaming. A transcoding platform is described herein that, in certain embodiments, leverages distributed computing techniques to transcode content in parallel across a platform of machines that are preferably idle or low-utilization resources of a content delivery network. The transcoding system also utilizes, in certain embodiments, improved techniques for segmenting the original source file so as to enable different segments to be sent to different machines for parallel transcodes.

Multiple service label types may be used in a given network element to optimize scalability of the data plane, minimize overhead associated with service label management, and allow new services to be offered. Service label management may be done in a dynamic manner so that service labels may be selected for routes in a dynamic fashion as the network changes. VPNs handled by the network element may have different types of service labels, and different routes within a particular VPN may be allocated different service label types. Service label requests may be stored on the data plane to allow a service label request database to be restored from the data plane upon a control plane failure, so that new service labels are not required to be allocated after a control plane failure.

When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. By turning on a reproduction switch, a picture file is read out from the nonvolatile memory means, the compressed data is expanded and converted to an analog signal, and the converted picture is displayed on a liquid crystal display. By pressing a display feed key, another picture file is read out and displayed. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. The nonvolatile memory means can be removed. By mounting this memory means on a printer unit, display unit or picture transmission unit, the digital camera also can be used during print, display or transmission of the picture. If multi-screen print is carried out on the printer unit, a vertical direction of each picture is unified. Further, upon reprint operation for multiple order persons, sorting work after the print is facilitated by providing with an identification means for identifying each order person.

A network quality control system includes a user control console to probe, calculate, and display the quality of an enterprise's network connections to remote SNMP managed devices supporting real-time services like VoIP. Traceroute-like messages are sent to each remote SNMP managed device to report on the path, and hop latency, jitter, and packet losses. MOS scores are computed to indicate performance with a variety of available codec's. Empty test packets used simply to probe network quality are not used. Instead, SNMP messages that carry valuable information or commands for other purposes are gleaned of timing information so the MOS quality scores can be calculated in background.

A system and method for retracting an electronic mail document stored in a mail database of a Server sent from a sender to a recipient. A fetch monitor at the Server monitors activity on the mail document and marks the status of the mail document accordingly. A fetch control issues a request to retract the mail document to a fetch queue at the Server. The request is retrieved by a fetcher at the Server from the fetch queue, which then proceeds to retract the mail document based on the marked status of the mail document, and then reports the retraction.

Embodiments of the invention may be used to manage message queues in a parallel computing environment to prevent message queue deadlock. A direct memory access controller of a compute node may determine when a messaging queue is full. In response, the DMA may generate an interrupt. An interrupt handler may stop the DMA and swap all descriptors from the full messaging queue into a larger queue (or enlarge the original queue). The interrupt handler then restarts the DMA. Alternatively, the interrupt handler stops the DMA, allocates a memory block to hold queue data, and then moves descriptors from the full messaging queue into the allocated memory block. The interrupt handler then restarts the DMA. During a normal messaging advance cycle, a messaging manager attempts to inject the descriptors in the memory block into other messaging queues until the descriptors have all been processed.

The above amendments do not add any new matter. They merely correct matters of form and more clearly express the contents of the invention.

The present invention provides a flexible and dynamic notification system. A service node acts as a contact proxy for a subscriber, wherein each subscriber has various actual notification addresses associated with different networks or communication terminals. For each subscriber, the service node supports a common notification address, which is used by various notification services to send notification messages to the subscriber. Upon receipt of a notification message to a subscriber's common notification address, the service node will send the notification message to an appropriate one or more of the subscriber's actual notification addresses. The actual notification address may be predefined or may be selected based on various criteria, including a defined subscriber profile or presence information associated with the subscriber. Different actual notification addresses may be selected at any given time based on the selection criteria. Further, the service node may simultaneously forward multiple messages to different actual notification addresses.
