RISA Numerical Study of Flow and Pollutant Dispersion Characteristics in Urban Street Canyons
Publisher: American Meteorological Society
Abstract: The flow and pollutant dispersion in urban street canyons are investigated using a two-dimensional numerical model with the k?ε turbulent closure scheme. It is shown that the flow field is characterized mainly by the number ...
A Numerical Study of Thermal Effects on Flow and Pollutant Dispersion in Urban Street Canyons
Publisher: American Meteorological Society
Abstract: This study investigates thermal effects on the flow and pollutant dispersion in urban street canyons. A two-dimensional numerical model with a k?? turbulent closure scheme is developed, and the heat transfer between the ...
Urban Flow and Dispersion Simulation Using a CFD Model Coupled to a Mesoscale Model
Publisher: American Meteorological Society
Abstract: Flow and pollutant dispersion in a densely built-up area of Seoul, Korea, are numerically examined using a computational fluid dynamics (CFD) model coupled to a mesoscale model [fifth-generation Pennsylvania State ...
Distribution of Tropical Tropospheric Ozone Determined by the Scan-Angle Method Applied to TOMS Measurements
Publisher: American Meteorological Society
Abstract: This work describes the first method to determine the tropical tropospheric ozone column directly from the Total Ozone Mapping Spectrometer (TOMS) space-borne instrument based on the physical differences in ozone-column ...
A CFD Model for Simulating Urban Flow and Dispersion
Publisher: American Meteorological Society
Abstract: A three-dimensional computational fluid dynamics (CFD) model is developed to simulate urban flow and dispersion, to understand fluid dynamical processes therein, and to provide practical solutions to some emerging problems ...
Negative Input Shaped Commands for Unequal Acceleration and Braking Delays of Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A negative input shaped command is presented for flexible systems to reduce the residual oscillation under unequal acceleration and braking delays of actuators that are common issues in industrial applications. Against ...
Economic Analysis of Design Errors in BIM-Based High-Rise Construction Projects: Case Study of Haeundae L Project
Publisher: American Society of Civil Engineers
Abstract: Design errors are one of the major risk factors causing rework and delay. Therefore, accurate cost analysis of potential economic losses attributable to design errors is crucial from a practical point of view. This paper ...
The Influence of Coupled Sea Surface Temperatures on the Madden–Julian Oscillation: A Model Perturbation Experiment
Publisher: American Meteorological Society
Abstract: In this study, the authors compare the Madden?Julian oscillation (MJO) variability in the Goddard Laboratory for Atmospheres atmospheric general circulation model for two different sea surface temperature (SST) boundary ...
Intradiscal Microprobe With a Vibrational Optical Fiber for Diagnosis and Thermal Therapy of Discogenic Pain Due to an Annular Fissure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Major studies have shown that discogenic pain is the most common cause of chronic lower back pain, accounting for 40% of all the causes. Provocation discography—inducing pains by pressing nerve structures around the ...
Interannual Sea Surface Temperature Variability and the Predictability of Tropical Intraseasonal Variability
Publisher: American Meteorological Society
Abstract: The objective of this study is to examine the relationship between interannual SST variability and the activity and predictability of tropical intraseasonal variability (TISV). A 10-yr simulation forced by climatological ...
