Superior Court
For a sport obsessed with getting a round ball through a hoop, the shape of the new Naismith Memorial Basketball Hall of Fame seems entirely appropriate. The building is intersected by...

Structures: System Would Use Chain of Spheres to Absorb Impact on Structures
A Museum for the Heavens
Replacing a icon such as the Hayden Planetarium's thin-shelled concrete dome is not the most desirable assignment. But the design team for the new Frederick Phineas and Sandra...
Effects of Horizontal Vibration on Hopper Flows of Granular Materials
Microgravity Segregation in Binary Mixtures of Inelastic Spheres Driven by Velocity Fluctuation Gradients
Kinetic Theories of Rapid Granular Flows of Highly Inelastic Particles

Experimental Statistical Study of the Motion of a Particle on a Rough Surface
Engineers and Contractors Go Global
The telecommunication explosion and the rise of free-trade agreements are pushing consulting engineers and construction companies toward globalization, a trend seen in past decades among...
Scour Development at Isolated River-Bed Obstacles
Development of local scour was investigated for isolated obstacles on movable beds subject to clear-water scour. The resulting maximum scour depths, scour volumes, and obstacle displacements...
Computer Simulation of Dry Layered Granular Flow Down an Incline Composed of Grains
Experiments show that gravity-driven dry granular flows are essentially layered for smooth spheres. This paper describes layer-to-layer interaction in the flow. Assuming two-dimensional...
Numerical Simulation of a Sphere Moving Down an Incline with Identical Spheres Placed Equally Apart
This paper describes a numerical study of an elastic sphere moving down an incline with a string of identical spheres placed equally apart. Two momentum equations and a moment equation...
A Sphere Moving Down an Inclined Bumpy Surface
A sphere moving down a bumpy incline in the air is studied theoretically and experimentally. A method based on the principle of energy conservation is used to express the average velocity...
Unconfined Granular Materials Thermalized by Fluctuating Horizontal Surfaces
We calculate the solid fraction and granular temperature throughout assemblies of identical, smooth, inelastic spheres that are unconfined from above and thermalized from below by bumpy,...
Granular Flow on a Bumpy Inclined Chute
Theoretical predictions for steady, uniform granular flows of identical, smooth, nearly elastic disks and spheres on bumpy inclined chutes are obtained. Kinetic constitutive theory is...
Normal and Tangential Contact of Layered Spheres as Models of Joint Contact
The causes of cracking in degenerating cartilage are examined using analytical models of layered elastic spheres in normal and tangential contact. Vertical surface and deep radial cracks...
Microstructure and Stress Differences in Shearing Flows
Steady shearing flows of highly inelastic particles are simulated using rigid and slightly deformable sphere models. Large first normal stress differences in small systems are observed,...
Problems with Predicting the Transport of Pumiceous Sediments in the Coastal Environment
Pumice is often a major component of coastal sediments associated with subduction zone volcanic settings. Several recent studies in New Zealand have highlighted the difficulties of predicting...
Crossflow vs. Counterflow Air Stripping Costs
Crossflow towers offer a potential economic advantage over counterflow towers due to savings in fan power costs as well as material costs. These savings increase as contaminant volatility...
