Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements low » requirements c.w, requirements do, requirements cloud
low dimensional » two dimensional, one dimensional, multi dimensional
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "irrigation requirements low dimensional ((((array string) OR (array format))) OR (array imaging))".
• Adding a wildcard symbol may retrieve word variants: irrigation requirements low dimensional ((((array string) OR (array format))) OR (array imaging))*.
