RISFast k-Nearest-Neighbors Calculation for Interpolation of Radar Reflectivity Field
Publisher: American Meteorological Society
Abstract: To efficiently implement the interpolation methods (e.g., Shepard?s method and its variants) for the radar reflectivity field, a fast method that calculates the k-nearest-neighbor nodes (sampling points in radar volume ...
Ekman Layer Scrubbing and Shroud Heat Transfer in Centrifugal Buoyancy-Driven Convection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents large-eddy and direct numerical simulations of buoyancy-driven convection in sealed and open rapidly rotating cavities for Rayleigh numbers in the range 107–109, and axial throughflow Reynolds numbers ...
Research on Curved Layer Fused Deposition Modeling With a Variable Extruded Filament
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The process of layered additive manufacturing (AM) limits manufactured parts, which leads to the stair-step error, support structures and the anisotropy. Curved layer fused deposition modeling (CLFDM) has been proposed by ...
Flow and Heat Transfer Mechanisms in a Rotating Compressor Cavity Under Centrifugal Buoyancy-Driven Convection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a systematic study of flow and heat transfer mechanisms in a compressor disk cavity with an axial throughflow under centrifugal buoyancy-driven convection, comparing with previously published experimental ...
Borehole Stability Analysis in Fractured Porous Media Associated with Elastoplastic Damage Response
Publisher: American Society of Civil Engineers
Abstract: A dual-porosity finite-element model is presented for stability analysis of boreholes drilled in fractured porous media with the consideration of elastoplastic damage response. Governing differential equations adopted in ...
Topology Configuration of Actuator Failure Mode of a Novel Quadruped Robot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fault tolerance is an important characteristic of quadruped robots. Actuator failure mode is the basis for research of fault tolerance and motion planning of quadruped robots. In this paper, the combination of actuator ...
Type Synthesis of a Family of Novel Four, Five, and Six Degrees of Freedom Sea Lion Ball Mechanisms With Three Limbs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A family of novel mechanisms with three limbs called sea lion ball mechanisms (SLBMs) is investigated that looks like a sea lion playing with a ball. The SLBMtype mechanism is composed of an upper part and a lower part ...
Transient Analysis of Dam–Reservoir Interaction Using a High-Order Doubly Asymptotic Open Boundary
Publisher: American Society of Civil Engineers
Abstract: A high-order doubly asymptotic open boundary (DAOB) for the modeling of a semi-infinite reservoir with constant cross section is developed, in which the compressibility of water and the absorption characteristic of a ...
Design and Kinematic Analysis of a Novel Hybrid Kinematic Mechanism With Seven-Degrees-of-Freedom and Variable Topology for Operation in Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We propose a novel hybrid robot with seven degrees-of-freedom (DOF) and variable topology for operation in space. Design specifications of the space robot are presented for the type synthesis of hybrid mechanisms. Based ...
A Computational Geometric Approach for Motion Generation of Spatial Linkages With Sphere and Plane Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the problem of spatial linkage synthesis for motion generation from the perspective of extracting geometric constraints from a set of specified spatial displacements. In previous work, we have developed ...
