Settlement of Strip Foundations on Regularly Jointed Rock Masses
The analysis of a long, rigid strip foundation resting on the surface of a regularly jointed rock mass is presented. Two models of the overall rock mass are investigated; one in which...

A Geotechnical Analysis System with Applications for Drilled Shaft Foundations
The development and components of a geotechnical analysis system are described and illustrated for drilled shaft foundations. This finite element-based analysis system incorporates several...

Ultimate Capacity of Deep Foundation by a Rigid-Plastic Analysis
This paper is concerned with the determination of the axial ultimate capacity of a rigid pier on the basis of the theory of perfect plasticity. As an application of the upper bound theorem...

Subgrade Model for Static and Dynamic Response Analysis of Surface Foundations
A new subgrade model is presented for the static and dynamic response analysis of surface foundations. The model consists of a number of horizontal layer model units. Each model unit is...

Axial Capacity of Pressure-Injected Piles: A Cavity Expansion Model
The application of cavity expansion theory to the development of a mathematical model for predicting the ultimate axial capacity of pressure-injected piles in cohesionless soils is presented....

GIS:Technology for Transportation
Geographic Information Systems show promise as important tools for transportation engineers. As computer hardware continues to become less expensive and more powerful, and as the software...

Computer Utilization in Structural Engineering
This volume contains the papers presented at the 1989 Structures Congress sponsored by the Structural Division of the American Society of Civil Engineers that deal directly with the application...

MATRIX.BYU
MATRIX.BYU is a general purpose Fortran program for personal computers which provides a flexible and user friendly platform for the input and output of matrix data, the execution of standard...

Design of Plastic Piece Parts
This paper describes a computer assisted design process originally developed at the University of Wyoming and now implemented in commercial software. In order to address the need for broadly...

A Parallel Partitioning Method for Large-Scale Circuit Simulation
In this paper, we discuss a partitioning method for large-scale circuit in parallel computer simulation. The partitioning method maps the sparse and irregular circuit equations to a special...

Computer Aided Design of Monolithic Integrated Circuits
An algorithm has been developed to relocate the sites of electrical components and integrated circuits. The process simulates site location changes in order that path lengths of conductors...

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...

Stereolithography
Stereolithography is a three-dimensional printing process which produces accurate copies of CAD solid or surface models directly from CAD data. The process uses a moving laser beam, directed...

Risk of Waterborne Infectious Illness Associated with Diving in the Point Loma Kelp Beds, San Diego, CA
There is considerable interest in estimating the risk of bacterial and viral illness (i.e., disease, infection) associated with scuba diving in the Point Loma kelp beds located within...

Risk Assessment for TCE and Related Chemicals Based on Multi-Component, Multi-Media Transport Models
Trichloroethylene (TCE) is known to undergo anaerobic transformation and produces daughter products including dichloroethene, and vinyl chloride which have been known as possible carcinogenic...

Modeling of Gaseous Emission from Landfills and Other Area Sources
Several dispersion models based on the Gaussian equation are evaluated to assess their relative utility in modeling emission dispersion from an area source, such as a landfill. The VAPOR...

Analysis of Model Uncertainty Using Bayesian Monte Carlo
Bayesian Monte Carlo analysis combines Bayesian inference with standard Monte Carlo techniques to provide improved estimates of the uncertainty in water quality model parameters and results....

Longterm Response of Lakes to Acidic Deposition
The longterm response of lakes in the northeastern United States to different levels of acidic deposition was predicted by using a lumped parameter hydrologic/biogeochemical model, the...

Evaluation and Selection of RBC Models for Design of Domestic Wastewater Facilities
This study evaluated three existing models commonly used for the design of Rotating Biological Contactors (RBC). Operating data from six RBC Treatment Plants located in eastern Massachusetts...

Simulation of Oxygen Dynamics in the Vadose Zone
A microcomputer model VIP (Vadose Zone Interactive Processes) was developed as an extension of the RITZ model to provide a mathematical description of land treatment systems for the disposal...
