[1] The Aerodyne Aerosol Mass Spectrometer (AMS) has been designed to measure size-resolved mass distributions and total mass loadings of volatile and semivolatile chemical species in/on submicron particles. This paper describes the application of this instrument to ambient aerosol sampling. The AMS uses an aerodynamic lens to focus the particles into a(More)
EPA, it has not been subjected to the Agency's required peer and policy review and therefore does not necessary reflect the views of the Agency, and no official endorsement should be inferred. The authors thank the MTA for their cooperation, including Chris Bush for providing bus fleet information and Dana Lowell for help in organizing the logistics of the(More)
improvement is tunable by selective placement of the presented error-correcting designs. When coupled with error correction code to protect in-pipeline memories, the BISER flip-flop design improves chip-level SER by 10 times over an unprotected pipeline with the flip-flops contributing an extra 7–10.5% in power. When only soft errors in flips-flops are(More)
Pulmonary inflammation can contribute to the development of lung cancer in humans. We investigated whether pulmonary inflammation alters the genotoxicity of polycyclic aromatic hydrocarbons (PAHs) in the lungs of mice and what mechanisms are involved. To model nonallergic acute inflammation, mice were exposed intranasally to lipopolysaccharide (LPS; 20(More)
This paper presents a new and effective multisensor based control strategy for high-accuracy/precision and high-efficiency automatic robot localization and calibration. The strategy combines both coarsely visual servo and fine position-sensitive detector (PSD) servo control methods. In a large field of view, an image-based visual servo control system is(More)
Point cloud registration and sensor calibration are two critical technical issues concerning robot-mounted, area sensor systems. Iterative closest point (ICP)-based algorithms developed in the past are commonly used for point cloud registration. However, due to its least squared fitting nature, registration quality depends on how closely the measured part(More)
This paper introduces a fully automated dimensional inspection (ADI) system using a digital area sensor. Instead of measuring a part surface point-by-point using a Coordinate Measuring Machine (CMM), an ADI system can measure a part surface patch-by-patch. Therefore, the inspection time can be significantly reduced. Many existing sensor planners were(More)
BACKGROUND The Affymetrix GeneChip® system is a commonly used platform for microarray analysis but the technology is inherently expensive. Unfortunately, changes in experimental planning and execution, such as the unavailability of previously anticipated samples or a shift in research focus, may render significant numbers of pre-purchased GeneChip®(More)
This paper introduces a novel robotic range sensor planning system, which is developed for 3D dimensional inspection of automotive body parts. For active, triangulation-based range sensors, shadow and reflection causes problems when measure a metal part with glossy and discontinuous surface. To solve these problems, a feedback based dynamic view planning(More)
This paper presents new calibration methods for a robotic area sensing system developed for industrial manufacturing inspection. A pixel-to-pixel calibration scheme is introduced to obtain standoff and baseline distance of the developed area sensor. In the three-dimensional (3D) space, the area sensor also has an offset angle in a plane parallel to the(More)
