RISSpatial Pattern Analysis of Urban Sprawl: Case Study of Jiangning, Nanjing, China
Publisher: American Society of Civil Engineers
Abstract: Over the past 30 years, land development and consumption have been out of control and have kept expanding blindly, especially to marginal areas of some metropolises in China. The conflict caused by urban sprawl among ...
The Strength of the Brewer–Dobson Circulation in a Changing Climate: Coupled Chemistry–Climate Model Simulations
Publisher: American Meteorological Society
Abstract: The strength of the Brewer?Dobson circulation (BDC) in a changing climate is studied using multidecadal simulations covering the 1960?2100 period with a coupled chemistry?climate model, to examine the seasonality of the ...
Analytical Approach for Detection of Multiple Cracks in a Beam
Publisher: American Society of Civil Engineers
Abstract: An analytical approach for the detection of a beam with multiple cracks is presented in this article. The method is based on the bending vibration theory of Euler-Bernoulli beam and the cracks are treated as massless ...
Experimental and Numerical Evaluation of the Film Cooling Characteristics of the Multicavity Tip With Inclined Film Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the complex flow field and the considerable heat load on the turbine blade tip, film cooling is essential to protect the tip from being overheated. In this paper, an experimental work was conducted to compare the ...
Measurement of Viscoelastic Fluid Flow in the Curved Microchannel Using Digital Holographic Microscope and Polarized Camera
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to develop a threedimensional (3D) measurement approach to investigate the flow structures of viscoelastic fluid in the curved microchannel by using digital holographic microscope (DHM). The measurement ...
Bandgaps of Two Dimensional Phononic Crystals With Sliding Interface Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present paper, the DirichlettoNeumann map method is employed to compute the band structures of twodimensional phononic crystals with smoothly sliding connection conditions between the matrix and the scatterers, which ...
Evolution of Water Vapor Concentrations and Stratospheric Age of Air in Coupled Chemistry-Climate Model Simulations
Publisher: American Meteorological Society
Abstract: Stratospheric water vapor concentrations and age of air are investigated in an ensemble of coupled chemistry-climate model simulations covering the period from 1960 to 2005. Observed greenhouse gas concentrations, halogen ...
Expressway Visual Distance Detection Using Thermal Imager: Comparing Normal and Infrared Images
Publisher: American Society of Civil Engineers
Abstract: The real-time monitoring of visibility for expressway traffic safety cannot be widely achieved due to the high cost of the traditional method. This paper proposes a novel method to monitor expressway visibility using two ...
Identification of Multivariable Hammerstein CARMA System Using Special Test Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The multivariable Hammerstein controlled autoregressive moving average (CARMA) system contains the sum of bilinear parameter vectors in the identification model, which is difficult to be transformed into a regression form ...
Heat Transfer Characteristics of the Multicavity Tips at Different Turbulence Levels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comprehensive understanding of the tip heat transfer characteristics is important to the blade tip design. In this work, the heat transfer coefficient (h) data of several multicavity tips was measured using a steady-state ...
