Perhaps you should try some spelling variations:
variational segmentation » variational formulation, variational iteration
estimation segmentation » restoration segmentation, optimization segmentation, formation segmentation
multidimensional array » multidimensional arrays, multidimensional data, multidimensional nmr
fast multidimensional » based multidimensional, a multidimensional, _ multidimensional
array string » array strong, arrays strings, array sharing

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((estimation segmentation) or (variational segmentation)) fast multidimensional array string~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((estimation segmentation) OR (variational segmentation)) fast multidimensional array string.
• Adding a wildcard symbol may retrieve word variants: ((estimation segmentation) or (variational segmentation)) fast multidimensional array string*.
