Perhaps you should try some spelling variations:
coded apertures » coded aperture
munich lectures » union lectures
berkeley coded » berkeley modell, berkeley d.d, berkeley lord
unix lectures » union lectures, six lectures, index lectures

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: (( berkeley coded apertures ) OR ( berkeley ((unix lectures) OR (munich lectures)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( berkeley coded apertures ) or ( berkeley ((unix lectures) OR (munich lectures)) ))".
• Adding a wildcard symbol may retrieve word variants: (( berkeley coded apertures ) or ( berkeley ((unix lectures) OR (munich lectures)) ))*.
