Automatic segmentation of fiber bundles can be beneficial to quantitative analysis on neuropsychiatric diseases. Previous clustering methods for fiber segmentation typically specify the number of clusters in advance or rely on prior knowledge. In this paper, we develop a new segmentation algorithm based on density-peaks clustering, in which the number of clusters can arise intuitively. This clustering...
Selective maintenance policy and cannibalization policy are two very important fleet maintenance policies, but the two fleet maintenance policies have not been considered jointly yet. This paper proposes a selective maintenance model considering cannibalization. First of all, model assumptions are expounded, such as system configuration, system performance, mission description, multiple maintenance...
This paper presents a novel FFT algorithm based on a multi-dimensional index mapping method. Twiddle factor multiplications are decomposed in a divide and conquer approach to minimize the number of multipliers and remain the simpleness of the butterfly computation. And canonic signed digit representation is applied to constant multiplications introduced from the decomposition. By exploiting the symmetry...
