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...

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,...

Design Data of Kaplan and Bulb Turbine Units
Some basic statistical data covering geometrical and energy parameters for Kaplan and bulb turbine units are presented. These data are further compared as specific rations for both units,...

Real-time Animation of Construction Activities
As a result of 3-D computer modeling, the availability of geometric data in an electronic form makes possible the use of computers for purely construction activities in ways that were...

Design Data of Pump-Turbine and Francis Turbine Units
Some basic statistical data covering geometrical and energy parameters for Francis turbine and Pump-turbine units are presented. These data are further compared as specific ratios for...

Reliability of Geometrically Nonlinear Structures
A procedure for first- and second-order, finite-element reliability analysis of geometrically nonlinear structures under static loads is presented. Structures are either linear or nonlinear...

Random Vibrations of Geometrically Nonlinear Finite Element Structures
A finite element formulation combined with stochastic linearization method is developed to study the large amplitude vibration characteristics of structures subjected to random loadings....

Reliability Study of Randomly Imperfect Beam-Columns
In this study, the effect of random initial geometric imperfections was treated as a set of equivalent random initial forces. This concept enables the direct employment of existing stochastic...

Pipe Geometry and Pipeline Bridge Wind Oscillation
Static and modal analyses of two pipeline suspension bridges owned by American Natural Resources - the Patterson Loop Aerial Crossing (PLAC) with a span of 850 feet (259 meters) and the...

Friction Factor and Patterns in Armor Coats
Recent observations of friction factors at armor coat forming discharges suggest the presence of distinct geometric patterns in the locations of the coarsest grains in armor coats. A statistical...

Expert System for Mixing Zone Analysis of Aqueous Discharges (CORMIX1): Further Developments
Two recent publications have reported the development of the Cornell Mixing Zone Expert System (CORMIX) for the analysis, prediction and design of aqueous toxic or conventional pollutant...

Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
