RISModeling, Force Sensing, and Control of Flexible Cannulas for Microstent Delivery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a kinetostatic modeling framework for flexible cannulas (concentric tubing robots) subject to tip loads. Unlike existing methods that allow fast computation of the beam tip ...
Design of Planar Parallel Robots With Preloaded Flexures for Guaranteed Backlash Prevention
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The precision of parallel robots is limited by backlash in their joints. This paper investigates algorithms for designing inexpensive planar parallel robots with prescribed backlash-free workspace. ...
Probabilistic Approach to Assessing Scoured Bridge Performance and Associated Uncertainties Based on Vibration Measurements
Publisher: American Society of Civil Engineers
Abstract: Whereas application of sensors that directly detect bridge scour at the foundation may be hindered because of their installation difficulty and vulnerability to floods, the identified scour rarely has been used to assess ...
Simulated Atlantic Multidecadal Oscillation during the Holocene
Publisher: American Meteorological Society
Abstract: he Atlantic multidecadal oscillation (AMO) and its possible change during the Holocene are examined in this study, using long-term simulations of the earth system model Community Earth System Models (COSMOS). A quasi-persistent ...
Nonequilibrium Thermal Fluctuations of Flow in Thermal Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fouling is detrimental to the heat transfer performance of concentrated solar power plant components where heat exchange takes place with the cooling tower water. Wave elements cause an expression of deep insight of the ...
A Regional Model Simulation of the 1991 Severe Precipitation Event over the Yangtze–Huai River Valley. Part I: Precipitation and Circulation Statistics
Publisher: American Meteorological Society
Abstract: The summer Mei-yu event over eastern China, which is strongly influenced by large-scale circulation, is an important aspect of East Asian climate; for example, the Mei-yu frequently brings heavy precipitation to the ...
Modeling and On-Line Estimation of Electrode Wear in Resistance Spot Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electrode wear is inherent in the resistance spot welding process. It determines the electrical and mechanical contact condition and thus strongly affects the resistance spot weld quality. A ...
Disturbance Compensation Using Feedforward and Feedback for Scanner Direct Current Motor Mechanism Low Speed Regulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For finer scan resolutions, the scan bar is required to move at slower speeds. Speed regulation at such low speeds presented a challenge for control. An approach successfully addressed this issue was developed. The disturbance ...
Integrated Design Procedure for Epoxy Asphalt Concrete–Based Wearing Surface on Long-Span Orthotropic Steel Deck Bridges
Publisher: American Society of Civil Engineers
Abstract: Wearing surfaces are integral parts for long-span orthotropic steel deck bridges and well-designed wearing surfaces will be able to carry the traffic crossing the bridge smoothly and maintain the operation of the bridge. ...
Self-Similarity Analysis of Turbulent Wake Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the self-similarity properties in the far downstream of high Reynolds number turbulent wake flows. The growth rate of the wake layer width, dδ/dx; the decaying rate of the maximum velocity defect, ...
