Abstract: Increased storage capacity and decreased power consumption are two key motivations in the development of hard disk drive (HDD) storage products. Two ideas that address these areas have recently received attention in the ...

Abstract: The ability to predict surface roughness effects is now well established for gas bearings that satisfy the requirements for either high wave number–limited or high bearing number–limited conditions. However, depending ...

Abstract: Analytical methods and techniques are required for design and analysis of low clearance gasbearings that account for the combined influence of surface roughness and Knudsen number. Analytical methods for the lubrication ...

Abstract: In order to better manage computational requirements in the study of thermal conduction with shortscale heterogeneous materials, one is motivated to arrange the thermal energy equation into an accurate and efficient form ...

Abstract: Numerical solution of heat conduction in a heterogeneous material with small spatial and time scales can lead to excessive compute times due to the dense computational grids required. This problem is avoided by averaging ...

Abstract: In this paper a new approach is presented to increase the time-step size for an explicit discontinuous Galerkin numerical method. The attributes of this approach are demonstrated on standard tests for the shallow-water ...

Abstract: The El Niño?Southern Oscillation (ENSO) signal in Antarctic precipitation is evaluated using European Centre for Medium-Range Weather Forecasts (ECMWF) operational analyses and ECMWF 15-yr (1979?93) reanalyses. Operational ...

Abstract: esults are presented from experiments performed with the Community Climate System Model, version 4 (CCSM4) for the Coupled Model Intercomparison Project phase 5 (CMIP5). These include multiple ensemble members of ...
