Abstract: A parallelized sparse field method for segmenting a volume dataset is provided. Using a processor a level set field within a multi-dimensional dataset comprising a plurality of voxels is initialized in parallel operation. The multi-dimensional dataset is indicative of an object. An initial set of active voxels is then generated in parallel operation in dependence upon the initialized level set field. New active voxels are determined in parallel operation. Duplicate active voxels are then removed in parallel operation, followed by compacting the active voxels in parallel operation. The process is repeated until a quantitative stopping criterion is met and level set segmentation data indicative of a feature of the object are determined in dependence upon the level set field.

Abstract: A method for texture characterization is provided. Multi-dimensional spectrum data are determined by transforming multi-dimensional image data into Fourier domain. The multi-dimensional spectrum data are partitioned into a plurality of partitions, wherein each partition is associated with a predetermined set of orthogonal voice frequencies. The partitioned multi-dimensional spectrum data are then transformed into Stockwell domain resulting in discrete orthonormal Stockwell transform data. The discrete orthonormal Stockwell transform data are then processed to determine data associated with image texture, which are indicative of a feature of the object.

Abstract: A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.

Abstract: A method for texture quantification is provided. Data indicative of a complex-valued local spatial frequency distribution in space-frequency domain are determined by processing a multi-dimensional image data set based on a Stockwell transform with a phase term corresponding to spatial locations of respective frequency components being expressed in terms of radial distance and angle of orientation. The complex-valued local spatial frequency distribution is indicative of a feature of the object. Data indicative of a low frequency energy distribution are determined by filtering the data indicative of a complex-valued local spatial frequency distribution using a band-pass filter having a predetermined low frequency energy bandwidth.

Abstract: The apparatus comprises a gripping-operating unit including a gripping subassembly, a base subassembly for mounting the components of the unit and an operating subassembly. The gripping subassembly includes a gripper, from which, at one of its vertical extremity, a lever, integral with the gripper, extends horizontally. The base subassembly generally includes an elongated body and a positioning-attachment element connected to the latter. The operating subassembly comprises a spring guide block with opposed channels, a helical compression spring, located in one of the channels, and a pushing pin having a tooth like extension. Should the lever act on the pushing pin, the later, via the tooth like extension, operates against the helical compression spring, and simultaneously moves beyond the spring guide bloc. When a lock is used, a subassembly strike-stopper and a lock actuator-stopper deactivator subassembly are included.

Abstract: A method for segmenting a volume dataset is provided. During initialization a level set field within a volume dataset is initialized and an initial set of active voxels is determined in dependence upon the initialized level set field. In an iteration process the level set field for the set of active voxels is updated followed by updating of the set of active voxels. The iteration is continued until the number of active voxels is less than a predetermined threshold. Level set segmentation data are then determined in dependence upon the level set field and provided for, for example, graphical display or storage.

Abstract: The present invention relates to a method and system for processing a volumetric dataset for providing close-up visualization of a subset therefrom. A volumetric dataset is processed based on a dual access gradient quantization data structure. The data structure is generated in a fast pre-processing stage and provides substantially immediate access to a quantized gradient using either an index or an arbitrary normalized vector. The method provides a clear, enlarged high-resolution image of a user selected region of interest at interactive rates and allows the user to freely move and visualize the region of interest within the volumetric dataset and with any orientation.

Abstract: Confidential entry of orders to purchase company shares in an equity offering can include an order entry module, order book module, and security module. The order entry module receives orders directly from investors to purchase shares of the company. Each order includes order information such as an identity of the investor that submitted the order, share price, and quantity of company shares to be purchased at the share price. The order book module communicates the order information to members of a management/equity capital markets company team for the equity offering transaction. The security module allows the order entry module to receive the orders directly from the investors, allows the order book module to communicate the order information to the members of the management/company team, and prevents communication of the order information to sales persons associated with the equity offering transaction.

Abstract: A method of monitoring the fire resistance of hydraulic fluids involves measuring a property of the hydraulic fluid that changes as the hydraulic fluid is used; relating the measurement to the fire resistance of the hydraulic fluid; and if necessary, taking remedial action in order to improve the fire resistance of the hydraulic fluid. A suitable property is the molecular weight of polymer anti-mist additives such as polymethyl methacrylate and the fire resistance may be improved by adding to the hydraulic fluid, a concentrate of the polymer in a suitable solvent when the measured molecular weight falls below an acceptable value.
