RISClimatology and Interannual Variability of Convectively Coupled Equatorial Waves Activity
Publisher: American Meteorological Society
Abstract: limatology and interannual variability of convectively coupled equatorial wave (CCEW) activity, including the mixed Rossby?gravity (MRG), tropical-depression-type (TD-type), equatorial Rossby (ER), and Kelvin waves, are ...
Microstructure and Oxidation Behavior of Narrow Gap Brazing and Wide Gap Brazing Joints With Boron/Silicon-Free Nickel Base Braze Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the microstructure and solidus and liquidus of several Ni-Co-Hf-Zr-Ti-Al braze alloys were first examined with the objective to develop a B- and Si-free low-melting braze alloy for narrow gap (NGB) and wide ...
Stability of Homogeneous Slopes: From Chart to Closed-Form Solutions and from Deterministic to Probabilistic Analysis
Publisher: ASCE
Abstract: Slopes are rarely homogeneous. However, stability solutions for homogeneous slopes are still useful because simple assumptions on ground conditions have to be made when there is no or little site investigation, typically ...
High Temperature Radiation Heat Transfer Performance of Thermal Barrier Coatings With Multiple Layered Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Meeting the demands for ever increasing operating temperatures in gas turbines requires concurrent development in cooling technologies, new generations of superalloys, and thermal barrier coatings ...
The Transfer Matrix Impedance Coupling Method for the Eigensolutions of Multi-Spool Rotor Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the transfer matrix impedance coupling method for calculating the eigensolutions of multi-spool rotor systems with several intershaft bearings is developed. This method can also ...
On the Longwave Climate Feedbacks
Publisher: American Meteorological Society
Abstract: his paper mainly addresses two issues that concern the longwave climate feedbacks. First, it is recognized that the radiative forcing of greenhouse gases, as measured by their impact on the outgoing longwave radiation ...
Time-Varying Response of ENSO-Induced Tropical Pacific Rainfall to Global Warming in CMIP5 Models. Part II: Intermodel Uncertainty
Publisher: American Meteorological Society
Abstract: AbstractAnomalous rainfall in the tropical Pacific driven by El Niño?Southern Oscillation (ENSO) is a crucial pathway of ENSO?s global impacts. The changes in ENSO rainfall under global warming vary among the models, even ...
K-Fold Exosystem and the Robust Nonlinear Servomechanism Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Asymptotic tracking and disturbance rejection in uncertain nonlinear systems is studied in the context of output feedback control. This study is facilitated by formalizing the notion of k-fold ...
On the Robust Regulator for Linear Systems With Limited Parameter Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linear servomechanism problem has been studied for two extreme cases. On one extreme, the problem has been studied without considering the plant parameter uncertainty. On the other extreme, ...
Optimizing the Feedback Gains of the Robust Linear Regulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to improve the transient response of a linear regulator system by optimizing the feedback gains associated with a fixed set of desirable eigenvalues of the closed-loop system. ...
