Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements using » requirements modeling
using dimensional » one dimensional, high dimensional, n dimensional
array imaging » arrays imaging, airway imaging, ray imaging
array along » arrays long, array arcing, array paving
arrays load » arrays brad

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

• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements using dimensional ((((array along) OR (arrays load))) OR (array imaging))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements using dimensional ((((array along) or (arrays load))) or (array imaging))*.
