RISStochastic Perturbation of a Pure Convective Motion
Publisher: American Meteorological Society
Abstract: In this note we study a simple truncated spectral model of a fluid in a pure convective motion due to Lorenz (1963). We find that where the equations are perturbed by a stochastic Wiener process (white noise), the system ...
On the Use of Point Source Solutions for Forced Air Cooling of Electronic Components—Part II: Conjugate Forced Convection From a Discrete Rectangular Source on a Thin Conducting Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model for uniform parallel flow over the surface of a rectangular source of heat on a conducting plate is used to demonstrate the use of analytic Green’s functions to formulate the conjugate ...
On the Use of Point Source Solutions for Forced Air Cooling of Electronic Components—Part I: Thermal Wake Models for Rectangular Heat Sources
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analytical solutions are presented for the temperature field that arises from the application of a source of heat on an adiabatic plate or board when the fluid is represented as a uniform ...
Design of Reset Control Systems: The PI + CI Compensator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reset compensation has been used to overcome limitations of linear and time invariant (LTI) compensation. In this work, a new reset compensator, referred to as proportional and integral (PI) + ...
The Mid-Quaternary Climatic Transition as the Free Response of a Three-Variable Dynamical Model
Publisher: American Meteorological Society
Abstract: A simplified version of a previously described dynamical model governing global ice mass, atmospheric carbon dioxide, and mean ocean temperature (that may also be a proxy for some other CO2?controlling oceanic variable, ...
Equilibration of a Simple Baroclinic Flow in a β Channel and on the Sphere
Publisher: American Meteorological Society
Abstract: The statistical equilibration of baroclinic waves in a two-level quasigeostrophic model subject to forcing and dissipation is studied. The model employed may be formulated in either spherical or Cartesian geometry and is ...
Ensemble streamflow forecasting across the U.S. middle Atlantic region with a distributed hydrological model forced by GEFS reforecasts
Publisher: American Meteorological Society
Abstract: he quality of ensemble streamflow forecasts in the U.S. middle Atlantic region (MAR) is investigated for short- to medium-range forecast lead times (6-168 h). To this end, a regional hydrological ensemble prediction system ...
A Model of the Internal Feedback System Involved in Late Quaternary Climatic Variations
Publisher: American Meteorological Society
Abstract: Because of the small net rates of energy flow involved in very long-term changes in ice mass (10?1 W m?2) it will be impossible to proceed in a purely deductive manner to develop a theory for these changes. An inductive ...
An Approach for Determination of Basic Machine Tool Settings From Blank Data in Face Hobbed and Face Milled Hypoid Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conditions of meshing and contact in hypoid gear drives depend substantially on the machinetool settings to be applied. Determination of gear geometry is the first step in the design process of a hypoid gear drive. An ...
Regionalization of the Hargreaves Coefficient for the Assessment of Distributed Reference Evapotranspiration in Southern Italy
Publisher: American Society of Civil Engineers
Abstract: The Hargreaves equation (HE) is the most reliable and diffused temperature-based method for the estimate of the reference crop evapotranspiration
