Perhaps you should try some spelling variations:
telecommunication applications » telecommunications applications, communication applications, telecommunication examinations
applications set » applications seta, applications self, applications soft
spaces » dspaces
dspaces » ddspaces
dddspaces » ddddspaces
space » dspace

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: "telecommunication applications set (((spaces OR dspaces) OR dspaces) OR dddspaces) euclidean space~".
• Adding a wildcard symbol may retrieve word variants: telecommunication applications set (((spaces OR dspaces) OR dspaces) OR dddspaces) euclidean space*.
