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. ...
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 ...
Fiber Orientation in Composite Structures for Optimal Resistance to Creep Failure
Publisher: American Society of Civil Engineers
Abstract: The objective of this research is to provide an approximate but reliable method of assessing various fiber configurations in a metallic composite structure with the intent of achieving optimal resistance to creep failure. ...
Distinct Modes of Internal Variability in the Global Meridional Overturning Circulation Associated with the Southern Hemisphere Westerly Winds
Publisher: American Meteorological Society
Abstract: he internal variability of the global meridional overturning circulation (GMOC) in long-term integration of the earth system model Community Earth System Models (COSMOS) is examined in this study. Two distinct modes of the ...
New Rock Bolt Model and Numerical Implementation in Numerical Manifold Method
Publisher: American Society of Civil Engineers
Abstract: A beam-element-based rock bolt model is proposed in this paper. The proposed model can not only simulate the compression and tension deformations of bolts in the rock block but also capture the interaction between the bolt ...
Prediction of the Waviness Error in Ultra-Precision Fly Cutting Using the Direct Integration Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fly cutting is widely used in manufacturing of large-scale, high-precision optical components. However, the discontinuity of fly cutting machining leads to significant relative vibrations between the tool and the workpiece. ...
Relationship between the Asian Westerly Jet Stream and Summer Rainfall over Central Asia and North China: Roles of the Indian Monsoon and the South Asian High
Publisher: American Meteorological Society
Abstract: AbstractDiagnostic analyses are performed to investigate the relationship between the upper-level Asian westerly jet stream (AWJS) and the associated rainfall pattern over the AWJS region in boreal summer on interannual ...
Torque Converter Capacity Improvement Through Cavitation Control by Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heavy cavitation in torque converters can have a significant effect on hydrodynamic performance, particularly with regards to the torque capacity. The objective of this study is to therefore investigate the effects of pump ...
Electrocoagulation of Dairy Manure Using Low-Carbon Steel Electrodes for Phosphorus Removal
Publisher: ASCE
Abstract: With the recent trend of increasing size for the dairy operations, dairy manure, due to its high content of phosphorus and relatively low nitrogen/phosphorus ratio, is limited when applied in the area where phosphorus is ...
