Elastic Stability of Non-Rectangular Plates
Non-rectangular plates may have infinite number of geometric configurations. Idealized pattern of practical shapes is chosen to be a sample for these plates. The present paper is concerned...

Flexural and Extensional Motion of Moderately Thick Laminated Composite Plates
A general theory of flexural and extensional motion of moderately thick laminated composite plates is developed for linear elastic materials and small deformation. Interlaminar stresses...

Plate Load and Pressuremeter Testing in Saprolite
On the island of Oahu, Hawaii, an exploratory tunnel for the Interstate Route H-3 highway was completed in December 1989. The purpose of the exploratory tunnel was two-fold; first to locate...

The Weathering of Spilled Crude Oil in Coastal Water Environment
A research project was conducted at the Technical Research Centre of Finland (VTT) in order to study the long-term behaviour of spilled crude oil in the brackish water under cold and icy...

A Flow Forecasting System for Hydro Power
The flow forecasting system comprises a network of meteorological stations, a weather forecasting model, and a watershed hydrologic model, implemented in a microcomputer. The meteorological...

Erosion Potential of Pacific Basin Precipitation
Average annual erosivity (EI) values were developed using 20 years of hourly precipitation data from weather stations located on each of 10 Pacific Basin islands. Average annual erosivity...

Common Mistakes in Model Applications
To apply models to groundwater problems, the hydrologist generally uses the following three-phased approach: (1) system conceptualization, (2) history matching (or model calibration),...

Soil-Rock Transition Zone: Uncertainties for Design and Construction
This paper addresses the problem of establishing definitions of the soil-rock boundary with regard to different engineering applications in the Piedmont geologic provinces. Three engineering...

Perception and Control for Automated Pavement Crack Sealing
Pavement maintenance is a major transportation engineering activity that has seen only partial mechanization and virtually no automation. Crack sealing is a typical maintenance task in...

Design Considerations for Automated Pavement Crack Sealing Machinery
The purpose of this paper is to discuss the numerous considerations for designing automated machinery for the sealing of cracks in pavement. Operational requirements are presented and...

Automated Analysis of Pavement Distress Data
A system model that can be used for the analysis of pavement distress data collected by various visual devices (e.g. photographic film) is presented. The models operate at two levels:...

Pavement Image Processing Using Neural Networks
This paper discusses the potential for employing neural network models in the pavement image interpretation and classification stage of an automated pavement condition evaluation system....

Flexible Pavement Distress Evaluation Using Image Analysis
A unique combination of image histogram and projection histogram are employed to classify major distress types on flexible pavement. This technique has taken into account the presence...

Joint Spacing for Airfield Pavement
This paper looks at various factors affecting portland cement concrete(PCC) pavement cracking, with special emphasis on the effect of joint spacing on crack development. A rational approach...

Runway Roughness Measurement, Quantification and Application: The Boeing Approach
The measurement of runway roughness and the determination of the severity of runway roughness have long been the subject of nebulous discussion and esoteric description. By considering...

Recycling Bituminous Runway Pavement into Aggregate Base Course
The paper discusses the development of recycling existing bituminous runway pavement by pulverizing into aggregate base course. To best explain the design, construction procedures and...

Results of the 1989 ASCE Airfield Pavement Survey
In November of 1989, the American Society of Civil Engineers Airfield Pavement Committee sent out questionnaires to airfield pavement engineers across the country to assess the most recent...

Automating Airfield Condition Data Collection
This paper discusses the advantages and disadvantages of the newest technology for the data collection requirements of an airport interested in implementing a pavement management system....

A Design for Automated Pavement Crack Sealing
An automated crack sealing system can have substantial economic benefits including reduced labor costs, improved quality, and improved safety. While automating crack sealing is technically...

Mass-Transfer Analysis of Waste Packages Containing Defense Waste Processing Facility Glass as a Waste Form
The fractional release rates of selected radionuclides from waste packages containing Defense Waste Processing Facility (DWPF) glass are calculated using the AREST code, assuming a continuous-diffusive...
