RISOn the Uncertainty of Wind Power Predictions—Analysis of the Forecast Accuracy and Statistical Distribution of Errors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work the uncertainty of wind power predictions is investigated with a special focus on the important role of the nonlinear power curve. Based on numerical predictions and measured data ...
Vital Life Supports for N.Y.C. Through the 20Th Century
Publisher: American Society of Civil Engineers
Abstract: A broad overview is presented of the water and wastewater programs of New York City. Each “life support system” is the product of long term plans which can retain their basic thrust for as long as a century. One key to ...
ADPIC—A Three-Dimensional Particle-in-Cell Model for the Dispersal of Atmospheric Pollutants and its Comparison to Regional Tracer Studies
Publisher: American Meteorological Society
Abstract: A hybrid Lagrangian-Eulerian atmospheric transport-diffusion model was developed to calculate the three-dimensional distribution of atmospheric pollutants in transient-region flow fields. This Atmospheric Diffusion ...
Transferability of a Three-Dimensional Air Quality Model between Two Different Sites in Complex Terrain
Publisher: American Meteorological Society
Abstract: The three-dimensional, diagnostic, particle-in-cell transport and diffusion model MATHEW/ADPIC is used to test its transferability from one site in complex terrain to another with different characteristics, under stable ...
On the Origin of “Rotating Instabilities”—Stability and Frequency Studies of Channel Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A group of unsteady flow phenomena in turbomachinery is often referred to as “rotating instabilities.” They occur at flow conditions with very asymmetric velocity profiles, as found downstream of blade rows in axial ...
Long‐Term Strength Development of Pavement Concretes
Publisher: American Society of Civil Engineers
Abstract: Development of pavement concrete compressive strength, flexural strength, and splitting tensile strength as a function of time is discussed. Eighteen sets of post‐1985 exerimental data from academic and industrial sources ...
Inertial and Frictional Effects on Stratified Hydrostatic Airflow past an Isolated Heat Source
Publisher: American Meteorological Society
Abstract: Inertial and frictional effects on stratified hydrostatic airflow past an isolated warm region are investigated by linear theories. For an inviscid quasi-geostrophic flow, there exists in the lower layer upward motion ...
A Theory of Cyclogenesis Forced by Diabatic Heating. Part II: A Semigeostrophic Approach
Publisher: American Meteorological Society
Abstract: A linear quasi-geostrophic theory of coastal cyclogenesis proposed by Lin has been extended by a semigeostrophic model. The response of an east?west backsheared, quasi-geostrophic baroclinic flow over an isolated heat ...
Part-Load Behavior of a Solar-Heated and Fossil-Fueled Gas Turbine Power Plant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solar energy can be converted effectively into electrical or mechanical energy. The radiant heat of the sun is collected by a parabolic dish, concentrated intensely, and reflected into a cavity ...
On the Generalized Frequency Response Functions of Volterra Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The generalized frequency response function (GFRF) for Volterra systems described by the nonlinear autoregressive with exogenous input model is determined by a new mapping function based on its ...
