学术论文 基于FPGA的工业X-CT二代扫描控制系统研究
工业X-CT（X-ray Computed Tomography）无损检测技术是以不损伤或者破坏被检测对象的一种高新检测技术，被誉为最佳的无损检测手段，在无损检测领域日益受到人们的青睐。近年来，各国都在投入大量的人力、物力对其进行研究与开发。 目前，工业CT主要采用第二代和第三代扫描方式。在工业CT第三代扫描方式中，扫描系统仅作“旋 ...

Each arc of a binary-state network has good/bad states. The system reliability, the probability
that source s communicates with sink t, can be computed in terms of minimal paths (MPs). An
MP is an ordered sequence of arcs from s to t that has no cycle. Note that a minimal path is
different from the ...

The frequency domain plays an important role in image
processing to smooth, enhance, and detect edges of images. Although
image data typically does not include imaginary values, the fast Fourier
transform (FFT) has been used for obtaining spectra. In this paper,
the fast Hartley transform (FHT) is u ...
