Enhancing Multi-Distance Phase Retrieval via Unequal Interval Measurements
Photonics, 2021 In the conventional methods of multi-distance phase retrieval, the diffraction intensity patterns are recorded at equal intervals, which can induce slow convergence or stagnation in the subsequent reconstruction process.

Aircraft positioning using multiple distance measurements and spline prediction
Aviation, 2022 During the crucial phases of take-off, initial climb, approach, and landing where aircraft are close to the ground, Global Navigation Satellite Systems (GNSS) signal strength may not be sufficient to guarantee safe operation, especially in the presence ...

Bhattacharyya’s distance measure as a precursor of genetic distance measures
Journal of Biosciences, 2004 In Population Genetics, two populations are distinguished from each other on the basis of the differences in the distributions of the alleles at the locus or loci under consideration. These differences are measured by a “genetic distance” between the two populations (not to be confused with genetic distance between two loci, which is based on ...

Distance measures for embedded graphs [PDF]
Computational Geometry, 2021 We introduce new distance measures for comparing straight-line embedded graphs based on the Fréchet distance and the weak Fréchet distance. These graph distances are defined using continuous mappings and thus take the combinatorial structure as well as the geometric embeddings of the graphs into account.
