Micromechanics of Material-Removal Mechanisms from Brittle Surfaces: Subsurface Damage and Surface Microroughness
LLE Review, Volume 74 131 The cold processing of optical glasses usually involves rough grinding, microgrinding, and polishing. In microgrinding,1,2 the resulting brittle-material-removal rate produces a cracked layer near the glass surface, referred to as subsurface damage (SSD). [Editor’s note: The acronym for subsurface damage (SSD) used in this article should not be confused with its more c...

LLE Review, Volume 73 45 In cold processing of optical glasses by microgrinding,1,2 the resulting brittle-material-removal rate induces a cracked layer near the glass surface, referred to as subsurface damage (SSD). [Editor’s note: The acronym for subsurface damage (SSD) used in this article should not be confused with its more common use as an acronym for smoothing by spectral dispersion.] In ...
متن کاملSubsurface Imaging using Ground-Penetrating Radar Measurements
Much work has been done toward reconstructing the electrical parameters of an unknown buried object. Many methods, and accompanying results from simulations, have been presented. Most research in the area, however, has been in developing imaging algorithms that have been tested primarily through computer simulation. This paper presents a newly constructed facility for ground-penetrating radar e...
متن کاملRobotic Subsurface Mapping Using Ground Penetrating Radar
The goal of our research is to develop an autonomous robot for subsurface mapping. We are motivated by the growing need for mapping buried pipes, hazardous waste, landmines and other buried objects. Most of these are large scale mapping problems, and to manually construct subsurface maps in these cases would require a significant amount of resources. Therefore, automating the subsurface mapping...
متن کاملPrecision and Recall Without Ground Truth
In this paper we present a way to use precision and recall measures in total absence of ground truth. 1 Precision and Recall 1.1 General Definitions and Notation Precision Pr and Recall Rc (and often associated F-measure or ROC curves) are standard metrics expressing the quality of Information Retrieval methods [8]. They are usually expressed with respect to a query q (or averaged over a series...
