Dynamic Stability of Cable Domes
The cable domes designed by David Geiger for the gymnastics and fencing arenas for the Olympics at Seoul, Korea, and for the stadium at St. Petersburg, Florida, are geometrically non-linear...

A Stratified Percolation Model for Saturated and Unsaturated Flow Through Natural Fractures
The geometry of the asperities of contact between the two surfaces of a fracture and of the adjacent void spaces determines fluid flow through a fracture and the mechanical deformation...

Brick Design for the Lunar Surface

Force and Geometry Constraints in Robot Excavation
One interest in this research effort was to develop and test an automatic control approach to adjust machine motions to the force conditions encountered during excavation - essentially...

Fractal Dimension of Cracks Found in Drying Sludge

Study on Hydrologic Response Via Channel Network Geomorphology
A drainage basin consists of slopes and channels. Slopes are the main fields at which rainfall input is converted into discharge. Stream-channels are the main fields at which the discharge...

Variational Method in Fluvial Hydraulics—A Review
The theoretical base of the principle of minimum energy dissipation rate and other related stationarity hypotheses have been reviewed. Recent applications of the theory to the calculation...

Blocking of Layered Flows in Channels of Gradually Varying Geometry

Issues of Rate Structure, Scaling, and Aggregation in Ecological Risk Analysis

Form Follows Geometry
The $107 million NCNB Plaza in Tamps, Fla. consists of a 32 floor, 500,000 sq ft, 455 ft tall office tower; a 40,000 sq ft, 78 ft tall banking hall, and a 280,000 sq ft parking garage...

Erosion Processes in Upland Areas
After a soil particle is detached and entrained, it will be transported by the surface runoff. However, depending on the eroding and transport capacities of the surface runoff, some of...

Hydraulic Geometry of Mississippi Hill Streams
Hydraulic geometry data based on field and office studies are presented for a series of streams in the Black Creek and Long Creek watersheds in the upland hills of Central and Northern...

Geometrical Nonlinearity in Offshore Pipelines
Pipelines are very flexible structural systems which are subjected to various boundary conditions. For instance, during the laying process, the pipes roll on the guidance tracks on the...

Geometric Non-Linearities in Cable Tray Assembly Seismic Response

Local Wind Pressures on Roofs
The paper reviews the results of the most recent research studies in the evaluation of wind pressure coefficients for the design of roof cladding elements. The effect of roof geometry...

Constraint Based Design from Research into the Classroom
Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified...

A Minimal Input Computer Aided Manufacturing Program for Personal Computers
The author presents here an algorithm developed in Pascal for an integrated two and a half dimensional CAD/CAM system. The geometry and the tool paths are defined simultaneously, thereby...

Relationship Between Channel Migration and Radius of Curvature on the Red River
The system behavior of meanders was investigated on the Red River between Shreveport, LA, and Index, AR. The effects of plan form geometry (r/w) and erodibility of bank material on the...

Conditional Simulation of the Wilmington Sand-Shale Sequence, Los Angeles Basin
In shaly clastic reservoirs at a scale where vertical cross flow cannot be ignored the main source of heterogeneity is the apparent random geometry of the sand-shale sequence. That geometry...

The Lower Mississippi River and the Coriolis Force
Weather patterns and large bodies of water respond to the forces generated by the earth's rotation. A large north-south flowing river, such as the Lower Mississippi River,...
