Perhaps you should try some spelling variations:
"sediment sampling algorithm" » "sediment mining algorithm" (Expand Search), "sediment samples algorithm" (Expand Search), "sediment sample algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element de algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (Expand Search), "present data algorithms" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element ore algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element rf algorithm") OR ("element data algorithms"))) OR ("sediment sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element rf algorithm\") OR (\"element data algorithms\"))) OR (\"sediment sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element rf algorithm ) OR ( element data algorithms ))) OR ( sediment sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element rf algorithm") OR ("element data algorithms"))) OR ("sediment sampling algorithm"))*.
