    摘要: This invention corresponds to a prosthesis for total or hip resurfacing replacement, which comprises a prosthetic femoral head made of highly cross-linked polyethylene, with a diameter ranging from 38 mm to 64 mm, to articulate with a cup or acetabular component made of metal. When the invention applies to total hip replacement, the polyethylene head includes a metal core, which contains inside the female counterpart (14) to mate with the male counterpart (13) of a Morse taper, located at the upper end of the femoral component. The use of this type of head for total hip replacement, articulated with an ultra-polished acetabular cup, reduces the risk of dislocation, transmits less angular and torque forces to the Morse taper than large metal heads, and avoids the problems related to the metal-metal bearing or with the use of large metal heads with thin polyethylene. When the invention relates to hip resurfacing replacement, the highly cross-linked polyethylene femoral head has a lower polyethylene extension or stem with or without internal metal reinforcement (151) or a metal stem integrated into a metal-back (152). Using these types of heads for hip resurfacing replacement heads eliminates the problems associated with metal-on-metal resurfacing replacements.

    摘要: A system and method for estimating a signal based on a stream of randomly generated samples. The method includes: (a) receiving a sample; (b) generating a sampling vector; (c) multiplying the sample and the sampling vector to obtain a current back projection; (d) computing a first intermediate vector that represents an average of the current back projection and previous back projections; (e) transforming the first intermediate vector to determine a second intermediate vector; (f) identifying locations where the second intermediate vector attains its k largest values; (g) computing an estimate for the transformation of the signal by solving a system of equations based on the identified locations, the received sample value, previously received sample values, the sampling vector and previously generated sampling vectors; (h) inverse transforming the transformation estimate to determine an estimate of the signal; and (i) storing the signal estimate.

    摘要: Method for detecting textural defects in an image. The image, which may have an irregular visual texture, may be received. The image may be decomposed into a plurality of subbands. The image may be portioned into a plurality of partitions. A plurality of grey-level co-occurrence matrices (GLCMs) may be determined for each partition. A plurality of second-order statistical attributes may be extracted for each GLCM. A feature vector may be constructed for each partition, where the feature vector includes the second order statistical attributes for each GLCM for the partition. Each partition may be classified based on the feature vector for the respective partition. Classification of the partitions may utilize a one-class support vector machine, and may determine if a defect is present in the image.

    摘要: A locking mechanism for securing a jumper tube to a shunt tube in a well screen assembly for use in gravel packing features a jumper tube having a telescoping connector that extends to engage the shunt tube and a locking mechanism that extends the connector the proper distance and then locks the connector into place by engaging lugs that are connected to the jumper tube. An apparatus and method for securing a connector tube to a well screen assembly features a receiver that is attached to the well screen assembly and is configured to receive a connector tube and secure the connector tube into place with screws. The receiver can be mounted to the well screen assembly via the shunt tube, a top/middle-bottom ring assembly, directly to the base pipe.
