Perhaps you should try some spelling variations:
"mobile learning convolution algorithm" » "mobile learning convolution algorithms", "mobile learning evolution algorithm", "mobile learning solution algorithm", "machine learning convolution algorithm"
"modified invasive estimation algorithms" » "modified invasive estimation algorithm", "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive ventilation algorithms", "modified passive estimation algorithms"

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: "((\"mobile learning convolution algorithm\") OR (\"modified invasive estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( mobile learning convolution algorithm ) OR ( modified invasive estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("mobile learning convolution algorithm") OR ("modified invasive estimation algorithms"))*.
