Determination Of The Thermal Offset Of The Eppley Precision Spectral Pyranometer
(Optical Society of America, 2001-10-01)
Eppley's precision spectral pyranometer (PSP) is used in networks around the world to measure down-welling diffuse and global solar irradiance at the surface of the Earth. In recent years several studies have shown significant ...
Understanding Active Noise Cancellation
Part II—Case Studies for a Synchronous Thermal Instability Operating in Overhung Rotors
In Part I, a theoretical model was developed for a synchronousthermal instability that is caused by differentialviscous shearing in bearings of overhung rotors. This secondpart used computer programs, which were based on ...
Part I—Theoretical Model for a Synchronous Thermal Instability Operating in Overhung Rotors
Atheoretical model has been developed for a synchronousthermal instability that is caused by differential viscousshearing in bearings of overhung rotors. This model employsan unbalance threshold criterion for instability ...
Variable Volumetric Stiffness Fluid Mount Design
Passive fluid mounts are commonly used in the automotive and aerospace applications to isolate the cabin from the engine noise and vibration. Due to manufacturing and material variabilities, no two identical fluid mount ...
Effectiveness and Acceptance of Adaptive Intelligent Speed Adaptation Systems
(The National Academies of Sciences, Engineering, and Medicine, 2008)
Intelligent speed adaptation (ISA) systems face significant consumer acceptance hurdles that limit the likelihood of widespread adoption, particularly in the United States. However, if these systems are designed as speed ...
Control of thermal runaway in microwave resonant cavities
(American Institute of Physics, 2002-09-15)
This article reports direct experimental evidence of the so-called "S curve" of temperature versus electrical field strength when materials with positive temperature dependence of dielectric loss are heated in a microwave ...
Stochastic simulation of enzyme-catalyzed reactions with disparate timescales
(CELL PRESS, 2008-10-01)
Many physiological characteristics of living cells are regulated by protein interaction networks. Because the total numbers of these protein species can be small, molecular noise can have significant effects on the dynamical ...
Multimodal system for harvesting magnetic and mechanical energy
(AIP Publishing, 2008-09-01)
In this letter, we investigate a multimodal system for simultaneous energy harvesting from stray magnetic and mechanical energies by combining magnetoelectric and piezoelectric effects. The system consists of a cantilever ...
The Effect of Spanwise Wall Oscillation on Turbulent Pipe Flow Structures Resulting in Drag Reduction
(AIP Publishing, 2007-12-01)
The results of a comparative analysis based upon a Karhunen-Loeve expansion of turbulent pipe flow and drag reduced turbulent pipe flow by spanwise wall oscillation are presented. The turbulent flow is generated by a direct ...
