Effect of Bathymetric Curvature on Gulf Stream Instability in the Vicinity of the Charleston Bump
Publisher: American Meteorological Society
Abstract: The effect of the isobathic curvature on the development and evolution of Gulf Stream frontal waves (meanders and eddies) in the vicinity of the Charleston Bump (a topographic rise on the upper slope off Charleston, South ...
Active Vibration Control of an Axially Moving Cantilever Structure Using PZT Actuator
Publisher: American Society of Civil Engineers
Abstract: In this article, vibration characteristics and active vibration control (AVC) of an axially moving cantilever structure are investigated. First, the vibration equation of an axially moving cantilever beam with variable ...
Development of a Two-Dimensional Fractal Model for Analyzing the Particle Size Distribution of Geomaterials
Publisher: American Society of Civil Engineers
Abstract: On the basis of the one-dimensional fractal model, a two-dimensional fractal model is developed to investigate the particle size distribution (PSD) of heterogeneous geomaterials. Based on the simulation results for PSD ...
BBR and DSR Testing of Aging Properties of Polymer and Polyphosphoric Acid–Modified Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: This work evaluated the effect of polymer and polyphosphoric acid (PPA) on the aging resistance of different asphalt binders with pressure-aging-vessel (PAV) aging. Two base asphalt binders, three polymers, one recycled ...
Design and Control of a Flexible Exoskeleton to Generate a Natural Full Gait for Lower-Limb Rehabilitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Strokes caused by cerebrovascular diseases often result in severe damage to locomotion, movement, and cognitive functions. Rehabilitation is an effective way to regain locomotion ability in daily life. However, there are ...
