A second-generation automated deburring cell is currently under development at the National Institute of Standards and Technology. This cell will be capable of automatically generating, from part geometry and machining information, a series of robot paths for deburring aerospace parts made from superalloys. In order to compensate for the inaccuracy of robots when following computed coordinates,...

In this letter report, core sediments from the Mt Elbert Stratigraphic Test Well #1 (Mt Elbert) located at Milne Point, Alaska were characterized in situ by high-pressure x-ray diffraction (HXRD). These samples represent part of the 500 ft (152.4 m) of continuous core collected from the D and C sands in the Mikkelson Tongue of the Canning Formation (BOSWELL et al., 2008). Research teams began c...

This paper builds on initial evidence of First Language influence on brass playing presented in Heyne and Derrick (2013) [13] by indicating how tongue positioning might affect trombone timbre. Ultrasound imaging of the tongue was used to compare vowel production and sustained trombone notes for three participants, one each of New Zealand English, Tongan and Japanese, whose musical production wa...

BACKGROUND Ceramic veneer fracture has occurred mainly at the incisal edge of the veneer because of greater stress. This study compares and evaluates the fracture resistance ceramic veneers with three different incisal preparations. MATERIALS & METHODS 15 human permanent maxillary central incisor extracted were selected which were divided into three groups of 5 each having a different Incial ...

The task and design requirements for a vision system for manipulator position sensing in a telerobotic system are described. Model-based analysis-by-synthesis techniques offer generally applicable methods with the potential to meet the system's requirement for accurate , fast and reliable results. Edge-based chamfer matching allows eecient computation of a measure, E, of the local diierence bet...

Journal bearings in typical applications are subjected to misalignment due several causes, such as shaft deformation under load and errors related the installation manufacturing processes. Misalignment has well-known severe negative consequences on performance of bearings. This paper deals with bearing chamfer reduce these misalignment, two forms edge modification considered analysis. These lin...

This paper presents an Augmented Reality system for aiding a pump assembling process at Grundfos, one of the leading pump producers. Stable pose estimation of the pump is required in order to augment the graphics correctly. This is achieved by matching image edges with synthesized edges from CAD models. To ensure a system which operates at interactive-time the CAD models are pruned o -line and ...

The following report discusses my work at the IDIAP from 06.2007 to 08.2007. This work had for objective to build a classifier for cat images, and focused on difficult images. Two approaches were implemented; one was using the Chamfer distance metric for matching, and the other learned models of our training images and used the Kullback-Leibler divergence as a metric of image comparison. Noise ...
