Frontal and tilted PDV probes for measuring velocity history of laser-shock induced calibrated particles

open access: yes, 2014
Photonic Doppler Velocimetry (PDV, also known as LDV or HetV) is a remarkable tool for measuring the different velocities of many objects simultaneously, including tiny individual reflectors such as particles ejected by the rear face of a metallic plate ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

open access: yesComputer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

PDV Probe Alignment Technique [PDF]

open access: yes, 2007
This alignment technique was developed while performing heterodyne velocimetry measurements at LLNL. There are a few minor items needed, such as a white card with aperture in center, visible alignment laser, IR back reflection meter, and a microscope to view the bridge surface. The work was performed on KCP flyers that were 6 and 8 mils wide.

Redefinition of Stemonosudis intermedia (Ege, 1933) and description of a new species from the western Atlantic Ocean (Aulopiformes: Paralepididae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract We examined specimens of slender barracudina in the genus Stemonosudis collected from the western Atlantic Ocean. Investigation revealed that seven specimens represent the first adult records of Stemonosudis intermedia (Ege, 1933), previously known only from juveniles. We redescribed S.
