Planning, Scheduling, and Communicating Effects on Crew Productivity
Construction project planning and scheduling along with communication of the plan have major impact on the productivity of field crews. Though the size of the impact is practically impossible...

Dynamic Estuary Model Performance
Applications of the Dynamic Estuary model (DEM) to both the Delaware and Potomac Estuaries by the Environmental Protection Agency during the 1970s are summarized and evaluated. Methods...

Modified Analysis of Reinforced Concrete Beams
A method for analyzing reinforced concrete beams and beam-columns is developed, and the analytical results are compared to experimental data obtained by other investigators. The present...

Node Factor Variations and Joint Occurences
In constructing exceedance frequency distributions for extremal heights resulting from joint occurrences of tsunamis or storm surges and the astronomical tide, a period of time for the...

Regulation of Engineers in California
State-administered certification programs for the engineering profession are unjustified and should be eliminated. The reasons for this conclusion have nothing to do with the peculiarities...

Sand Liquefaction: Inelastic Effective Stress Model
An effective stress numerical model for soil liquefaction, which provides interaction between shearing deformation and transient pore-water pressure development, is presented. Some attractive...

Economic Evaluation of Development Projects on Transportation ROW
The development and application of a computer model for testing the feasibility of multiple agency development projects at proposed transit stations is described. Given a development strategy,...

Conflicts of Roles in Engineering Ethics
An examination of how ethical dilemmas are created is presented and applied to engineering practice. Cases which are most typical of such conflicts are whistleblowing cases in which the...

Elastic Buckling of Laterally Continuous I-Beams
An approximate method for determining the elastic flexural-torsional buckling loads of laterally continuous structures is developed. The method can be applied to structures loaded at braced...

Self-aerated Flow in Steep, Partially Filled Pipes
The self-aerated flow in steep and partially filled conduits of circular shape is investigated. Prototype measurements are carried out on pipelines with slopes up to 1.0 (45°) and diameters...

Centrifuge Modeling of Lateral Earth Support
Using the centrifuge modeling technique, a series of reinforced lateral earth support model tests were performed to identify the possible failure mechanism, and to verify a limit equilibrium...

Lysimeters for Simulating Sanitary Landfills
An interdisciplinary team is investigating the various decomposing processes inside sanitary landfills. Eight different ways of operation of sanitary landfills are simulated by special...

Internal Hydraulic Jump in Stratified Counterflow
Based on a Boussinesq approximation of the governing momentum equations for an internal hydraulic jump in a two-layer counterflow, two important properties of an equal counterflow are...

Quality Control During Construction of Power Plants
The need for quality control during the construction of power plants has always been recognized as beneficial. Federal law requires a comprehensive program be provided to control and assure...

Routing Graded Sediments in Streams: Applications
A one-dimensional numerical model has been tested in simulating the movement of well graded sediments through a stream reach. The model is applied to two laboratory flumes and two alluvial...

Stochastic SH Waves along a Frictional Interface
The reflection, refraction, and adsorption of a planar SH wave with stochastic time dependence at a frictionally bonded interface between elastic solids is considered. The incident stress...

Noise in Earthquake Accelerograms
The amplitudes of processing and digitization noise in strong motion earthquake accelerograms are reviewed for hand and automatic digitization. By finding the period bands for which the...

Coal Conversion Solid Waste Disposal
The major solid waste produced at coal conversion facilities will be gasification slag or ash. To evaluate the impact of this waste on the environment, the Oak Ridge National Laboratory...

Reconversion to Coal Firing at Crystal River
Units 1 and 2 at the Crystal River Plant of Florida Power Corporation were originally designed for coal firing in the 1960's, were converted to heavy fuel oil firing in the early 1970's...

Protection of Pipelines Subject to Surcharge Loads
Surcharge loads from new fills, railroads, and structures often require design of reinforcement to increase the field supporting strength of existing sewers and storm drains. Pipelines...
