Title: A Novel Fluorescence Based Method of Assessing Subsurface Damage in Optical Materials
Author: Williams, Wesley
Date Created: 2009
Subjects--Topical: Mechanical engineering, Materials science, Optics
Description: Lapping and polishing are loose abrasive finishing processes that have been used to achieve critical surface parameters in optical materials for centuries. These processes remove material from the surface through a variety of mechanical and chemic...

Title: COMPRESSIVE IMAGING AND DUAL MOIRÉ LASER INTERFEROMETER AS METROLOGY TOOLS
Author: Abolbashari, Mehrdad
Date Created: 2013
Subjects--Topical: Optics, Engineering
Description: Metrology is the science of measurement and deals with measuring different physical aspects of objects. In this research the focus has been on two basic problems that metrologists encounter. The first problem is the trade-off between the range of ...

Title: Characterization of the Dynamic Performance of Machine Spindles
Author: Ganguly, Vasishta
Date Created: 2014
Subjects--Topical: Mechanical engineering
Description: Machine spindle dynamics and (axis of rotation) error motions may vary as a function of spindle speed due to gyroscopic effects, changes in bearing preload, centrifugal forces, and thermals effects. It is necessary to characterize these changes in...

Title: Optical super-resolution and periodical focusing effects by dielectric microspheres
Author: Darafsheh, Arash
Date Created: 2013
Subjects--Topical: Optics, Physics, Biomedical engineering
Description: Optical microscopy is one of the oldest and most important imaging techniques; however, its far-field resolution is diffraction-limited. In this dissertation, we proposed and developed a novel method of optical microscopy with super-resolution by ...

Title: Time Domain Approach to Stability in Machining Operations
Author: Berglind, Luke
Date Created: 2015
Subjects--Topical: Mechanical engineering
Description: Machine tool chatter is a common occurrence in machining environments which can lead to undesirable part outcomes and can even cause damage to the machine. Chatter is a result of regenerative dynamic forces inherent in the machining process which ...
