A relational database warehouse system with query optimization capabilities is described that allows for speedy identification of sets of records of interest from amongst tens of millions of records. The records of interest may include complex derived attributes, generated, at least in part, by aggregating data from a plurality of records in base data tables. In various embodiments, the query optimization capabilities allow the database warehouse system to identify conditions under which normal query execution may be replaced by one or more optimized execution methods, including, for example, eliminating unnecessary inner join operations on base data tables specified by a query, re-ordering the execution of group-by operations and left-outer join operations to greatly reduce the size of join tables produced while processing a query, and/or consolidating a set of segmentation queries for execution in one pass over the records of the database.

A computer-implemented method for double auction trade-building by matching, based on feasibility and price/cost heuristics, a plurality of electronically posted bid with a plurality of electronically posted ask records. A one-pass sequential trade building method selects ask records one at a time and sequentially inserts, in one pass, as many of the bid records as possible while maintaining feasibility criteria. A two pass sequential trade building method inserts the bid records in two stages, the first terminating when the trade becomes feasible and the second when no further bids can be inserted.

CBR control strategies provide constant or relatively constant bitrate output with variable quality. The control strategies include various techniques and tools, which can be used in combination or independently. For example, an audio encoder uses a trellis in two-pass or delayed-decision CBR encoding. The trellis nodes are states derived by quantizing buffer fullness values. The transitions between nodes of a previous stage and nodes of a current stage depend on encoding a current chunk of audio at different quality levels. When pruning the trellis, the encoder uses a cost function that considers smoothness in quality as well as quality in absolute terms. The encoder may store compressed data at different quality levels, then output the compressed data after simplification of the trellis to a suitable point. If the two-pass or delayed-decision CBR encoding fails, the encoder uses one-pass CBR encoding for the sequence or part of the sequence.

A blood pump has an impeller rotatably disposed and magnetically suspended within a cavity of a stator by a plurality of magnetic bearings (passive permanent and active electromagnetic) having impeller magnets on the impeller and stator magnets or coils/poles on the stator. A motor includes impeller magnets on the impeller and coils/poles associated with the stator. A single, annular blood flow path extends axially through the cavity between the impeller and the stator, and between the impeller magnets on the impeller and the stator magnets or the coils/poles on the stator.

System and method for constructing a 3D model of an object based on a series of silhouette and texture map images. In the exemplary embodiment an object is placed on a rotating turntable and a camera, which is stationary, captures images of the object as it rotates on the turntable. In one pass, the system captures a number of photographic images that will be processed into image silhouettes. In a second pass, the system gathers texture data. After a calibration procedure (used to determine the camera's focal length and the turntable's axis of rotation), a silhouette processing module determines a set of two-dimensional polygon shapes (silhouette contour polygons) that describe the contours of the object. The system uses the silhouette contour polygons to create a 3D polygonal mesh model of the object. The system determines the shape of the 3D model analytically-by finding the areas of intersection between the edges of the model faces and the edges of the silhouette contour polygons. The system creates an initial, (rough) model of the 3D object from one of the silhouette contour polygons, then executes an overlaying procedure to process each of the remaining silhouette contour polygons. In the overlaying process, the system processes the silhouette contour polygons collected from each silhouette image, projecting each face of the (rough) 3D model onto the image plane of the silhouette contour polygons. The overlaying of each face of the (rough) 3D model onto the 2D plane of the silhouette contour polygons enables the present invention to determine those areas that are extraneous and should be removed from the (rough) 3D model. As the system processes the silhouette contour polygons in each image it removes the extraneous spaces from the initial object model and creates new faces to patch “holes.” The polygonal mesh model, once completed, can be transformed into a triangulated mesh model. In a subsequent step, the system uses a deterministic procedure to map texture from the texture images onto the triangles of the 3D mesh model, locating that area in the various texture map images that is “best” for each mesh triangle.

An attribute-based speech recognition system is described. A speech pre-processor receives input speech and produces a sequence of acoustic observations representative of the input speech. A database of context-dependent acoustic models characterize a probability of a given sequence of sounds producing the sequence of acoustic observations. Each acoustic model includes phonetic attributes and suprasegmental non-phonetic attributes. A finite state language model characterizes a probability of a given sequence of words being spoken. A one-pass decoder compares the sequence of acoustic observations to the acoustic models and the language model, and outputs at least one word sequence representative of the input speech.

The present invention is a fast indexing technique that builds an indexing structure based on multi-level key ranges typically for large data storage systems. The invention is explained based on the B⁺-tree. It is designed to reside in main memory. Point searches and range searches are helped by early termination of searches for non-existent data. Range searches can be processed depth-first or breath-first. One group of multiple searches can be processed with one pass on the indexing structure to minimize total cost. Implementation options and strategies are explained to show the flexibility of this invention for easy adaption and high efficiency. Each branch of any level has exact and clear key boundaries, so that it is very easy to build or cache partial index for various purposes. The inventive indexing structure can be tuned to speed up queries directed at popular ranges of index or index ranges of particular interest to the user.

A method of developing natural language understanding (NLU) applications can include determining NLU interpretation information from an NLU training corpus of text using a multi-pass processing technique. The alteration of one pass automatically can alter an input for a subsequent pass. The NLU interpretation information can specify an interpretation of at least part of the NLU training corpus of text. The NLU interpretation information can be stored in a database, and selected items of the NLU interpretation information can be presented in a graphical editor. User specified edits also can be received in the graphical editor.

What is claimed is an inspection device for in-tube monitoring of main pipelines by the method of ultrasonic wall thickness metering realized in a device traveling inside the pipeline and performing measurements, acquisition of measurement data and their interpretation. The device comprises a probing pulse generator, an ultrasonic transducer, an amplifier, a comparator with an analog input, a digital timer, a processor and a data storage module, and a controlled reference voltage source connected in series. The output of said reference voltage source is connected to the reference voltage input of the comparator, said reference voltage source being capable of setting at least two different voltages at its output.

The comparator output is connected to one of the control inputs of the reference voltage source that allows one to switch threshold values in the comparator, when recording the ultrasonic pulses, to use one threshold value to record the moment of reception of the ultrasonic pulse reflected from the internal wall of the pipeline using another threshold value of the comparator to record the moment of reception of the ultrasonic pulse reflected from the external wall of the pipeline using the other threshold value. Thus, the operator can perform direct measurements of the transit time of the ultrasonic pulses in the pipe wall allowing him to increase the distance monitored per one pass of the device, and to increase the accuracy of measurements and the rate of hardware data processing compared to the prototypes known in the art.

A method, apparatus and program for booting a non-uniform-memory-access (NUMA) machine are provided. The invention comprises configuring a plurality of standalone, symmetrical multiprocessing (SMP) systems to operate within a NUMA system. A master processor is selected within each SMP; the other processors in the SMP are designated as NUMA slave processors. A NUMA master processor is then chosen from the SMP master processors; the other SMP master processors are designated as NUMA slave processors. A unique NUMA ID is assigned to each SMP that will be part of the NUMA system. The SMPs are then booted in NUMA mode in one-pass with memory coherency established right at the beginning of the execution of the system firmware.

One or more computer systems, a carrier medium, and a method are provided for creating a catalog for backup data using NDMP file history messages.

The messages comprise hierarchy information and attribute information for the nodes. For each message comprising hierarchy information, an entry may be created for the respective node in a catalog, and the hierarchy information for the respective node may be stored in the catalog. For each message comprising attribute information, the attribute information for the respective node may be stored in the catalog. The messages may be processed in a single pass without caching them all. A carrier medium may include program instructions which, when executed, cause the above operations on one or more computer systems.

The present invention is generally directed to powerful and flexible methods and systems for consensus sequence determination from replicate biomolecule sequence data. It is an object of the present invention to improve the accuracy of consensus biomolecule sequence determination from replicate sequence data by providing methods for assimilating replicate sequence into a final consensus sequence more accurately than any one-pass sequence analysis system.

A system and method for secure network communication. In various embodiments of the present invention, data needed for authentication an encryption is included in each communication pass between network devices, so that when a network connection is broken, a secure connection can be reestablished with the next pass. A client authentication service on the client receives a server request and searches for a current client-side session key. If one is not present, the client authentication service generates and encrypts an initial session key, acquires credentials, adds the credentials to the server request, and encrypts the server request with the initial session key. The encrypted server request and the encrypted session key are sent to the server, where a server authentication service decrypts the initial session key, decrypts the server request with the initial session key, and authenticates the credentials before allowing the server request to be acted upon. Where a current client-side session key is detected, the client authentication service acquires the current client-side session key, generates a next step session key, adds the next step session key to the server request, and encrypts the server request with the current client-side session key. The encrypted server request is sent to the server where the server authentication service decrypts the server request with a current server-side session key allowing the server request to be acted upon.

The present invention is directed to three-dimensional printing techniques, methodologies, systems and apparatus to facilitate increased print speed. Through the use of multiple nozzles on a print head printing line by line, more material is deposited. By including nozzles sufficient for a line dimensional (or portion) of a page or planar element of an object design, the material deposition for an entire plane or layer is done line by line in one pass of the print head. Likewise, through the inclusion of multiple lasers, beams or energy sources more material can be cured, such as all along a contour line, instead of point by point.

A multi-pass printing system and a corresponding method are provided for printing an image, which includes a plurality of continuous-tone values, based on halftone matrices having threshold values. The printed image is composed of sub-images, each of which includes dots printed in a respective pass. The sub-images present independent dot patterns at corresponding places. The printing system is arranged to obtain the sub-images by splitting the continuous-tone values into at least two pass values, an individual pass value indicating an intensity to be printed in a respective pass. Then, in one pass a first halftone matrix for printing the respective pass values, and in another pass one or more second halftone matrices are used, which are obtained by positionally shifting the threshold values of the first halftone matrix, for printing all pass values of the other pass, or at least those pass values above a highlight threshold.
