RISHigh Temperature Resistance of High-Content Limestone-Modified Sulfoaluminate Cement
Publisher: American Society of Civil Engineers
Abstract: AbstractThe high temperature resistance of ordinary portland cement concrete has obvious limitations
and is an important issue affecting the safety of concrete structures. A kind of high
temperature resistant cement was ...
Optimize Energy Efficiency of Quadrotors Via Arm Rotation
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Quadrotors have been used in many areas such as cargo transportation, agriculture, and search and rescue. The low energy density of power sources and the low energy efficiency of quadrotors have prevented quadrotors from ...
Kinematic Analysis and Optimal Design of a Novel Schönflies-Motion Parallel Manipulator With Rotational Pitch Motion for Assembly Operations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel Schönflies-motion Parallel Manipulator with RotationalPitch motion (SPM-RP) based on a single-platform fully parallel mechanism. An analysis of the position, workspace, velocity, and singularity ...
Fast Kinematic Calibration of a Robotic Manipulator Through a Single Continuous Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The measurement step of the existing calibration approaches for robotic manipulators can take a considerable amount of time to settle a robotic manipulator down at certain static configurations, making the calibration ...
Cable Path Analysis and Kinematic Control of a Cable-Driven Parallel Robot Allowing Cables to Wrap on Cylinders or Spheres
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Scholars have proposed to allow cables to wrap on the base, the end-effector, or obstacles to expand the workspace of a cable-driven parallel robot (CDPR) in recent years. However, it is not entirely clear whether the path ...
Enhancing Kinematic Calibration Accuracy for Parallel Manipulators Based on Truncated Total Least-Square Regularization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article proposes a novel kinematic calibration approach to address the ill-conditioned identification matrix problem and enhance the accuracy of parallel manipulators (PMs). The kinematic calibration approach applies ...
A Homogenized-Based Model for Estimating the Thermal Conductivity of Unsaturated Granular Soils
Publisher: American Society of Civil Engineers
Abstract: Abstract Granular soils are usually unsaturated consisting of solid particles, pore water,
and air, and the thermal conductivity of unsaturated granular soils is a basic parameter
for evaluating the deformation properties ...
A Spatial Variable-Structure Cable-Driven Parallel Robot Through Cables Wrapping Over a Convex Polyhedron
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The workspace of a cable-driven parallel robot (CDPR) in a complex environment is limited by obstacles and objects. To adapt a CDPR to a complex environment and enlarge the limited workspace, this article proposes ...
Medium- to Long-Term Forecasts of Sea Surface Height Anomalies using a Spatiotemporal Empirical Orthogonal Function Method
Publisher: American Meteorological Society
Abstract: A spatiotemporal empirical orthogonal function (STEOF) forecast method is proposed and used in medium- to long-term sea surface height anomaly (SSHA) forecast. This method embeds temporal information in empirical orthogonal ...
Real-Time Reconfiguration Planning for the Dynamic Control of Reconfigurable Cable-Driven Parallel Robots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The movable anchor points make reconfigurable cable-driven parallel robots (RCDPRs) advantageous over conventional cable-driven parallel robots with fixed anchor points, but the movable anchor points also introduce an ...
