Perhaps you should try some spelling variations:
"representative parameters characterizes" » "representative parameters characterized", "representative parameters characterize", "representative parameters characterise"
"representation parameters characterised" » "presentation parameters characterised", "representation parameters characterized", "representation parameters characterize", "representation parameters characteristic"

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: "((\"representative parameters characterizes\") OR (\"representation parameters characterised\"))~".
• Removing quotes may allow a broader search: (( representative parameters characterizes ) OR ( representation parameters characterised ))~.
• Adding a wildcard symbol may retrieve word variants: (("representative parameters characterizes") OR ("representation parameters characterised"))*.
