RISExploration of AFM Imaging Artifacts Occurring at Sharp Surface Features When Using Short Carbon Nanotube Probes and Possible Mitigation With Real-Time Force Spectroscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present an overview of four types of imaging artifacts that can occur during characterization of sharp sample topographies with intermittent contact atomic force microscopy (AFM) when using ...
Mixed-Layer Shear Generated by Wind Stress in the Central Equatorial Pacific
Publisher: American Meteorological Society
Abstract: Sixteen months of wind and current profile observations in the central equatorial Pacific show the response of the upper-ocean shear to local wind forcing. The shear at the ocean surface is significantly correlated with ...
Assessment of Temporally Conditioned Runoff Fractions in Unregulated Rivers
Publisher: American Society of Civil Engineers
Abstract: Increasing nonstationarity increases the uncertainty of hydrological processes. Consequently, intrinsic randomness increases in magnitude and occurrence. In order to generate a reliable and robust predictive model, time ...
Fields, Flows and Waves: An Introduction to Continuum Models

Analysis of Solar-Thermal Power Plants With Thermal Energy Storage and Solar-Hybrid Operation Strategy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Selected solar-hybrid power plants for operation in base-load as well as midload were analyzed regarding supply security (dispatchable power due to hybridization with fossil fuel) and low CO2 ...
Utilizing Off-Resonance and Dual-Frequency Excitation to Distinguish Attractive and Repulsive Surface Forces in Atomic Force Microscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A beam model is developed and discretized to study the dynamic behavior of the cantilever probe of an atomic force microscope. Atomic interaction force models are used with a multimode ...
Engineering Aspects of the Integration of Chemical and Biological Oxidation: Simple Mechanistic Models for the Oxidation Treatment
Publisher: American Society of Civil Engineers
Abstract: Oxidation processes can oxidize biorecalcitrant compounds into biodegradable intermediates, which in turn can be treated less expensively by a subsequent biological process. To design such a two-step (chemical+biological) ...
Sliding Mode Control of Nonlinear Mechanical Vibrations1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article we illustrate how the property of differential flatness can be advantageously joined to the sliding mode controller design methodology for the active stabilization of nonlinear ...
Tolerance Analysis With Polytopes in HV-Description
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article proposes the use of polytopes in HV-description to solve tolerance analysis problems. Polytopes are defined by a finite set of half-spaces representing geometric, contact, or functional specifications. However, ...
Transverse Reinforcement for Columns of RC Frames to Resist Earthquakes
Publisher: American Society of Civil Engineers
Abstract: An approximate formulation to determine the amount of transverse reinforcement for columns of reinforced concrete (RC) frames in seismic areas is presented. It is based on observations that suggested that the main function ...
