Abstract: A vibration testing system for structures visually displays vibration analysis information in the form of a graphic animation using a 3D model of the object. While only a subset of the surface points of the object model correspond to sensors on the structure, an interpolation feature of the system allows deformation information for all points of the model to be estimated. Interpolation weights can be calculated in advance to allow for real-time display of a test. Color can be used to enhance visualization of vibration amplitudes. The visualization can be performed offline after a vibration test has been completed to show modal analysis results or can be done in real-time using either blocks or RMS data obtained while the vibration testing is still on-going. This is especially useful for adjusting test parameters, such as the excitation location, amplitude or both, for more effective testing.

Abstract: Approximate nearest neighbor (ANN) searching is a fundamental problem in computer science with numerous applications in area such as machine learning and data mining. For typical graph-based ANN methods, the searching method is executed iteratively, and the execution dependency prohibits graphics processor unit (GPU)/GPU-type processor adaptations. Presented herein are embodiments of a novel framework that decouples the searching on graph methodology into stages, in order to parallel the performance-crucial distance computation. Furthermore, in one or more embodiments, to obtain better parallelism on GPU-type components, also disclosed are novel ANN-specific optimization methods that eliminate dynamic memory allocations and trade computations for less memory consumption. Embodiments were empirically compared against other methods, and the results confirm the effectiveness.
