Introduction Four generic types of construction robots have been suggested in [4]. They were an assembling robot, an interior finishing robot, an exterior wall finishing robot, and a horizontal floor finishing robot. The interior finishing robot, as explained there, was designated to execute various interior finishing operations, such as partition erection, painting, plastering, jointing, tapin...

When segmenting three-dimensional medical data using level sets, re-distancing the implicit surface is time-consuming. We propose a fast implementation, based on Chamfer distance, which preserves the interface location. Experiments using synthetic and real data show reasonable accuracy and considerable speed-up. 2005 Elsevier B.V. All rights reserved.

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...

OBJECTIVE This study compared occlusal contact areas of ideally planned set-up and accomplished final models against the initial in class I and II molar relationships at finishing. METHODS Evaluations were performed for 41 post-orthodontic treatment cases, of which 22 were clinically diagnosed as class I and the remainder were diagnosed as full cusp class II. Class I cases had four first prem...

A novel nanofinishing process using improved ball end magnetorheological (MR) finishing tool was developed for finishing of flat as well as 3D surfaces of ferromagnetic and non ferromagnetic workpieces. In this process a magnetically controlled ball end of smart MR polishing fluid is generated at the tip surface of the tool which is used as a finishing medium and it is guided to follow the surf...

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 ...

OBJECTIVE The purpose of this study was to evaluate the effect of tooth coating material and finishing agent on bleached enamel surfaces after using KTP laser with 27% hydrogen peroxide. BACKGROUND DATA There have been few reports on the effects of tooth coating materials and finishing agents after bleaching. METHODS After 40 crowns of human extracted maxillary incisors were bleached by KTP...

INTRODUCTION The finishing and polishing phases are essential to improve smoothness and shining on the surface of acrylic resins used to make removable orthodontic appliances. A good surface finishing reduces roughness, which facilitates hygiene, prevents staining and provides greater comfort to the patients. OBJECTIVE The aim of this paper was to analyze the changes on surface morphology of ...
