RISApplication of Kriging and Radial Basis Function for Reliability Optimization in Power Modules
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the design for reliability of a wire bond structure in a power electronic module based on computational approach that integrates methods for high fidelity analysis, reduced order modeling, numerical ...
Dynamical Response to the QBO in the Northern Winter Stratosphere: Signatures in Wave Forcing and Eddy Fluxes of Potential Vorticity
Publisher: American Meteorological Society
Abstract: ave?mean flow interactions associated with the Holton?Tan effect (HTE), whereby the tropical quasi-biennial oscillation (QBO) modulates the Northern Hemisphere wintertime stratospheric polar vortex, are studied using the ...
A Comparative Study of Wave Forcing Derived from the ERA-40 and ERA-Interim Reanalysis Datasets
Publisher: American Meteorological Society
Abstract: he Eliassen?Palm (E-P) flux divergences derived from ERA-40 and ERA-Interim show significant differences during northern winter. The discrepancies are marked by vertically alternating positive and negative anomalies at ...
Stratospheric Response to the 11-Yr Solar Cycle: Breaking Planetary Waves, Internal Reflection, and Resonance
Publisher: American Meteorological Society
Abstract: AbstractBreaking planetary waves (BPWs) affect stratospheric dynamics by reshaping the waveguides, causing internal wave reflection, and preconditioning sudden stratospheric warmings. This study examines observed changes ...
Downward Wave Reflection as a Mechanism for the Stratosphere–Troposphere Response to the 11-Yr Solar Cycle
Publisher: American Meteorological Society
Abstract: AbstractThe effects of solar activity on the stratospheric waveguides and downward reflection of planetary waves during NH early to midwinter are examined. Under high solar (HS) conditions, enhanced westerly winds in the ...

Experimental Study on Landslide-Generated Waves Overtopping in Reservoirs with Arch Dams
Publisher: American Society of Civil Engineers
Abstract: The overtopping process, resulting from landslide-induced waves, has the potential to cause significant damage to downstream infrastructures. To minimize the associated losses, it is essential to study the overtopping ...
