Design of Pre-excavated Scour Hole Below Flip Bucket Spillways
A number of tests were performed on a model-scale flip bucket spillway with a gravel-bed plunge pool in order to develop equations to describe the geometry of the scour hole created by...

Recovering Techniques and Possible use of the Geometry of Old Runners

Integrating Database and Geometric Modeling Technologies to Manage Facility Information
Existing engineering data models provide various means of representing, organizing and linking information about constructed facilities in a computer-integrated environment. However, they...

Use of Machine Vision in Bedform Studies

Modeling the Salinity History of Great Egg Harbor Bay, New Jersey

Classification of Jointed Rock with Emphasis on Grouting

Nondestructive Crack Identification by Acoustic Emission Analysis and Ultrasonic Frequency Response
Nondestructive evaluation (NDE) by the acoustic emission (AE) analysis and the ultrasonic testing (UT) on the spectral (frequency) response is studied to identify crack geometry. AE waveform...

Fracture Surface Characterization of Concrete
The objective of this paper is to characterize fracture surfaces of concrete, with varying maximum aggregate sizes dmax, by utilizing the concept...

Nonlinear Behaviour of Schneebeli Packings
We present some experimental proofs of the influence of the disorder of contacts on the mechanical (non-local) behaviour of packings of cylinders. In particular, this disorder is responsible...

Cylindrical Shell Redesign by Large Admissible Perturbations
Redesign (or inverse design) is the problem of defining an objective structural State S2 from its specifications and the known baseline State S1. The large admissible perturbations approach...

Stress Relaxation Analysis for Sealants
A solution method for stress relaxation analysis of systems composed linear viscoelastic material in a state of plane strain is presented. The incremental, finite element method takes...

Nonlinear Geometric and Material Considerations in Shell Structures
A geometrically and materially nonlinear static shell theory allowing large displacements, rotations, and strains with parabolic shear is developed. The theory is cast into a total Lagrangian...

Systolic Anterior Motion of the Mitral Valve: In Vitro Flow Studies
Using an in-vitro approach, the goal of this study was to determine and to characterize the mechanism of systolic anterior motion of the mitral valve in obstructive hypertrophic cardiomyopathy....

Analysis of Space Crane Articulated-Truss Joints
Three articulated-truss joint concepts for the space crane are studied to evaluate their static structural performance over a range of geometric design parameters. Emphasis is placed on...

Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...

Use of Fractal Geometry Concepts in the Simulation of Ground Water Flow and Transport Processes

Numerical and Analytical Description of Highway Surface Roughness

Experimental Verification of the Theoretical Solution of Laminated Glass Units

A Mathematical Model for Analysis of Laminated Glass Units

Designing for Control of Ice Conditions in Marinas
Each marina or small-craft harbor experiencing ice during the winter months must be designed for site specific conditions. These conditions are governed by environmental factors (geology,...
