FIBER BASED TOOLS FOR POLISHING OPTICAL MATERIALS
Title
FIBER BASED TOOLS FOR POLISHING OPTICAL MATERIALS
Author
Shahinian, Hossein
Date Created
2018
Subjects--Topical
Mechanical engineering, Optics
Description
In this dissertation, the development of alternative fiber based polishing tools for the finishing of precision freeform and aspherical optics is introduced. Freeform and aspherical optics, i.e. optics with varying radius of curvatures (ROC), are ...

Civil engineering
Description
The use of p-y curves is heavily engrained into geotechnical engineering practice. However, even with the prevalent use of p-y curves, these are only used to model the loading portion and not the unloading of a load test or loading demand in the f...

Description
With nonrigid parts, it is most convenient for designers to specify the desired shape in the design condition; that is, the shape is specified with all loads present that the part will experience in service (gravity, assembly constraints, etc.). T...
