RISOptimization Methods in Structural Design Practice
Publisher: American Society of Civil Engineers
Abstract: Structural optimization is examined from the viewpoint of structural design office practice. The costs and benefits of optimization are considered, as are the special requirements which practical design processes impose. ...
Extratropical Influences on the El Niño–Southern Oscillation through the Late Quaternary
Publisher: American Meteorological Society
Abstract: A sequence of numerical simulations with a coupled atmosphere?ocean general circulation model configured for particular times during the late Quaternary shows that simulated El Niño?Southern Oscillation (ENSO) events ...
Moments-Based Reduced Spectral Wave Modeling of Frequency-and-Directional Spreading Effects on Wave-Induced Longshore Currents
Publisher: American Society of Civil Engineers
Abstract: Often, nearshore radiation stresses are approximated using the monochromatic wave assumption, although this can have significant errors when the incident waves have finite frequency and/or directional spread. Consequently, ...
Current Trends in Antarctic Sea Ice: The 1990s Impact on a Short Climatology
Publisher: American Meteorological Society
Abstract: Antarctic sea ice extent, open water area, and ice area are shown to have increased significantly during the period 1987?96. These trends are largely attributable to an increase in these parameters during the mid-1990s. ...
Dynamics of Globally and Dissipatively Coupled Resonators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work explores the dynamics of arrays of globally and dissipatively coupled resonators. These resonator arrays are shown to be capable of exhibiting seemingly new collective behaviors which are highly sensitive to the ...
Tropopause Folds and Synoptic-Scale Baroclinic Wave Life Cycles
Publisher: American Meteorological Society
Abstract: The linear stability of three midlatitude zonal mean states of varying baroclinicity and barotropy is examined using a primitive equation stability analysis under the anelastic approximation. Each of these basic states ...
On the Dynamics of Two Mutually-Coupled, Electromagnetically-Actuated Microbeam Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work describes the modeling, analysis, predictive design, and control of self-excited oscillators, and associated arrays, founded upon electromagnetically-actuated microbeams. The study specifically ...
The Role of Atmospheric Dynamics and Climate Change on the Possible Fate of Glaciers in the Karakoram
Publisher: American Meteorological Society
Abstract: igh-resolution regional climate simulations for the Karakoram Mountain range in the greater Himalayas have been performed to investigate the atmospheric dynamics of this region, and their role in the Karakoram?s snowfall ...
On the Classification of Extreme Atlantic Hurricanes Utilizing Mid-Twentieth-Century Monitoring Capabilities
Publisher: American Meteorological Society
Abstract: n investigation is conducted to determine how improvements in observing capabilities and technology may have affected scientists? ability to detect and monitor Saffir?Simpson Hurricane Wind Scale Category 5 hurricanes in ...
Vehicle Pooling in Transit Operations
Publisher: American Society of Civil Engineers
Abstract: The benefits of pooling vehicles among routes that emanate from a common focus terminal are examined. In this strategy, trips are still scheduled, but vehicles are not assigned to specific trips. Instead, vehicles belonging ...
