    摘要： A “partial activation” method of magnetostrictive guided wave testing of a structure. A coil-wrapped magnetostrictive strip is acoustically coupled to the surface of the structure. A permanent magnet is placed over a portion of the strip, such that the permanent magnet covers all or most of the width of the strip but only a portion of its length. A pulsed alternating current source activates the magnetostrictive strip, thereby producing magnetostrictive vibrations in the magnetostrictive strip, and thereby resulting in guided waves in the structure. Response signals are received, then the permanent magnet is moved to a next position along the length of the magnetostrictive strip. As the magnet is moved along the strip, the strip is activated and response signals are received, thereby testing a desired portion of the structure under the strip. The response signals are analyzed to determine the presence of anomalies in the structure.

    摘要： A method for synchronizing list-mode data of single events in a PET imaging includes: acquiring list-mode data of single events of each independent detector module, calculating a probability density of time intervals between occurrences of single events in detector module and setting initial parameters, determining detection starting time difference of each detector module with iterative peak searching and graded time window, and performing synchronization correction and coincidence discrimination on the single event data in each detector module based on the detection starting time difference. A system for synchronizing list-mode data of single events in a PET imaging includes: a data acquisition and frequency difference compensation module, an initial parameter setting module, a coarse time scale coincidence module, a fine time scale coincidence module and a data synchronization correction and coincidence discrimination module.

    摘要： Ultrasound radiation using a single tone burst pulse is applied to a selected location in a tissue region. The induced shear wave is detected in the region and its spectral distribution is calculated and analyzed. This detection may be repeated with other excitation pulses having different widths or different shapes at the same location. The spectral analysis of the detected shear wave is performed according to a nonlinear shear model for solving nonlinearity and viscoelasticity of the tissue at a single location. The detection location can be at one point at a time for imaging two-dimensional or three-dimensional tissue nonlinearities and shear wave properties including nonlinear magnitude variations, nonlinear phase variations, nonlinear coefficients, and viscoelasticity. The induced shear wave are detected at multiple locations along the shear propagation directions for calculating different shear group velocities and different shear phase velocities using different excitation pulses, and calculating nonlinearity and viscoelasticity.

    摘要： A system and methods are provided for removal of undesired portions of a fruit or vegetable, such as removal of calyxes from strawberries before they are flash frozen. An automated process for high-throughput fruit or vegetable calyx removal includes a loading system, an identification system, and a removal system. The loading system is configured to transport the fruit or vegetable through the automated process. The loading system may also orient the fruits or vegetables along an axis of the fruit and or align the fruit or vegetables in a desired pattern, orientation, and/or arrangement. The identification system is configured to locate the calyx and determines calyx position data and an optimal cutting path for individual fruit. The removal system uses data received from the identification system to separate the calyx from the fruit or vegetable.
