RISThe Effect of Creep on Human Lumbar Intervertebral Disk Impact Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The intervertebral disk (IVD) is a highly hydrated tissue, with interstitial fluid making up 80% of the wet weight of the nucleus pulposus (NP), and 70% of the annulus fibrosus (AF). It has often been modeled as a biphasic ...
On the Formation of the Low-Level Jet over Texas
Publisher: American Meteorological Society
Abstract: The low-level jet (LLJ) in the winter half-year originates as a south wind over the high plains of Colorado. Kansas, western Oklahoma and West Texas. After formation, the LLJ spreads horizontally and upstream toward the ...
Assimilation of Stratospheric Temperature and Ozone with an Ensemble Kalman Filter in a Chemistry–Climate Model
Publisher: American Meteorological Society
Abstract: new stratospheric chemical?dynamical data assimilation system was developed, based upon an ensemble Kalman filter coupled with a Chemistry?Climate Model [i.e., the intermediate-complexity general circulation model Fast ...
Sensitivity of the Stratospheric Circulation to the Latitude of Thermal Surface Forcing
Publisher: American Meteorological Society
Abstract: sing the chemistry climate model Intermediate General Circulation Model?Fast Stratospheric Ozone Chemistry (IGCM-FASTOC), the authors analyze the response in the Northern Hemisphere winter stratosphere to idealized thermal ...
Comparison of SEAONC Base Isolation Tentative Code to Shake Table Tests
Publisher: American Society of Civil Engineers
Abstract: The base isolation subcommittee of the seismology committee of the Structural Engineers Association of Northern California (SEAONC) prepared a tentative code in 1986 for base‐isolated structures. Two main procedures were ...
Shake Table Test of Cylindrical Water Tanks in Base‐Isolated Structures
Publisher: American Society of Civil Engineers
Abstract: This paper presents the experimental results obtained from the study of two similar cylindrical water tanks. One of the tanks was directly fixed to the earthquake simulator, the other was mounted on the base of a scaled ...
Analysis of Infinite‐Strip‐Shaped Base Isolator with Elastomer Bulk Compression
Publisher: American Society of Civil Engineers
Abstract: Multilayered elastomeric bearings are a basic component in base isolation systems. Several design formulas that have been developed and used in the past consider the elastomer as incompressible. In this paper, the effect ...
Diagnosing the Annual Cycle of the Equatorial Undercurrent in the Atlantic Ocean from a General Circulation Model
Publisher: American Meteorological Society
Abstract: Ten-year-long output series from a general circulation model forced by daily realistic winds are used to analyze the annual cycle of the Equatorial Undercurrent (EUC) in the Atlantic Ocean. Two well-defined transport maxima ...
A Comparison of the Human Lumbar Intervertebral Disc Mechanical Response to Normal and Impact Loading Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thirtyfour percent of U.S. Navy high speed craft (HSC) personnel suffer from lower back injury and low back pain, compared with 15 to 20% of the general population. Many of these injuries are specifically related to the ...
Effects of Wall Calcifications in Patient-Specific Wall Stress Analyses of Abdominal Aortic Aneurysms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is generally acknowledged that rupture of an abdominal aortic aneurysm (AAA) occurs when the stress acting on the wall over the cardiac cycle exceeds the strength of the wall. Peak wall ...
