RISMoving Harmonic Load on a Prestressed Thick Strip Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is a study of the steady-state response of an initially stressed, thick strip plate subjected to a sinusoidally oscillating moving line load. The problem is studied on the basis ...
Microscale Warming due to Poor Ventilation at Surface Observation Stations
Publisher: American Meteorological Society
Abstract: AbstractScreen-level air temperature measurements at surface observation stations are influenced by local-site-scale factors. These local influences may affect global-scale climate change studies. This study investigated ...
Modeling and Nonlinear Vibration Analysis of a Rigid Rotor System Supported by the Magnetic Bearing (Effects of Delays of Both Electric Current and Magnetic Flux)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Active magnetic bearing (AMB) becomes widely used in various kinds of rotating machinery. However, as the magnetic force is nonlinear, nonlinear phenomena may occur when the rotating speed becomes ...
LES of Turbulent Separated Flow and Heat Transfer in a Symmetric Expansion Plane Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The LES method was applied to analyze numerically an unsteady turbulent separated and reattached flow and heat transfer in a symmetric expansion plane channel of expansion ratio 2.0. The ...
Evaluation of the J-Integral of a Crack in a Pressure Vessel Under Thermal Transient Loadings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To assure the safe design of reactor vessels, the parameters of the fracture mechanics are evaluated for an assumed crack subjected to internal pressure and thermal loading. Several kinds of ...
Representative Air Temperature of Thermally Heterogeneous Urban Areas Using the Measured Pressure Gradient
Publisher: American Meteorological Society
Abstract: A method to measure an area-averaged ground air temperature based on the hydrostatic equation is shown. The method was devised to overcome the problem of finding the most representative surface air temperature over a wide ...
A Noninvasive Method of Measuring Max(dP/dt) of the Left Ventricle by Doppler Echocardiography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although slightly affected by alterations in preload, the maximum first derivative of left ventricular pressure with respect to time, Max(dP/dt), is widely regarded as a simple and convenient ...
Roughness Lengths for Momentum and Heat Derived from Outdoor Urban Scale Models
Publisher: American Meteorological Society
Abstract: Urban climate experimental results from the Comprehensive Outdoor Scale Model (COSMO) were used to estimate roughness lengths for momentum and heat. Two different physical scale models were used to investigate the scale ...
Measurement of Turbulence Intensity in the Center of the Canine Ascending Aorta With a Hot-Film Anemometer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blood flow velocity near the central axis of the canine ascending aorta was measured with a hot-film anemometer. The cardiac output and the heart rate were controlled at will by means ...
Lapping of Electrical Discharge Machining Processed Tool Steel Surface Using Elliptical Tool Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A prototype lapping machine, which finishes surfaces by applying elliptical motions to a lapping tool in the presence of diamond compound, is developed. This paper describes the structure of ...
