The Use of Numerical Rule Processors in Engineering Calculations
A Numerical Rule Processor uses a declarative approach to the processing of engineering calculations. The rules which link the parameters are set out in a separate rule base and the order...

Simulative Calculation of Highrise Building Structure Under Vertical Loads
It is well known, the general structural stiffness and the vertical construction loads are formed storey by storey from bottom to top of the building especially for cast R.C. structure....

Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...

Sonic NDT for Infrastructure Assessment
Sonic Nondestructive Testing (NDT) techniques are valuable tools for assessing infrastructure. Relatively recent innovations in the field can reveal the internal conditions of concrete...

Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...

Reliability Assessment of Concrete Pavement Sawing
Traditional concrete pavement design sometimes realize on qualitative decision based on experience, with concrete pavement sawing operations representing a specific case in point. presently,...

Infrastructure Repair with Polymer Composite Using Recycled Plastics
Recycled poly(ethylene terephthalate), PET, mainly recovered from plastic beverage bottles, can be used to produce unsaturated polyester resins. Polymer concrete (PC) made with these resins...

Carrying Freight on High Speed Rail Lines
Some basic technical aspects of carrying freight on high speed rail lines are presented. To illustrate certain requirements and considerations, performance comparisons are made using three...

Texas High Speed Rail Ridership Forecasting
On May 28, 1991, the Texas High Speed Rail Authority made a decision to implement a High Speed Rail (HSR) system in the `Texas Triangle,' which would connect five of Texas' largest cities...

Intercity Travel Demand Modeling and Forecasting for High Speed Rail Service in the Quebec-Ontario Corridor
This paper describes the application of intercity travel demand models and preparation of ridership and revenue forecasts for the Ontario/Quebec Rapid Train Task Force in 1990. The development...

Selection and Analysis of Florida's High-Speed/Intercity Rail Routes
Events during 1990 and 1991 in Florida's High-Speed Rail Franchise process have driven the project toward the status of a public works project. With greater public participation than originally...

High Speed Rail Loading Scenario and Dynamic Tuning of Track
Similarities and differences exist between conventional and high speed rail (HSR) infrastructure design. The differences stem from the dynamic nature of the HSR loading scenario and the...

Dynamic Study on New Guideway Structure for JR Maglev
This paper presents an introduction of the study for the design and technical development of a newly proposed guideway structure for the superconductive magnetically levitated train system...

High-Speed Rail's Prospects in Canada
This paper reviews the attractiveness of high-speed rail in Canada. It summarizes the findings of studies on the subject by VIA Rail, Canada's national passenger rail corporation. VIA...

The French Master Plan for High-Speed Rail Services
Some 4,700 km (2,919 mi) of new line designed to operate at speeds of 350 to 400 kph (217 to 248 mph), associated with a network totaling some 11,000 km (6,832 mi) of existing lines upgraded...

The Technology of X2000?ABB's High Speed Tilting Train
The X2000 High Speed Tilting Train was developed by Asea Brown Boveri (ABB) in cooperation with the Swedish State Railways (SJ). The purpose of the project was to reduce trip times on...

ICE-HSR-System?Infrastructure, Rolling Stock, Operation
High-Speed trains such as the Japanese Shinkansen train in operation since 1964, the French TGV (train a grande vitesse) introduced in 1981 and the German ICE (InterCityExpress) running...

Making the Leap
Over the past decade, computers have become as much a part of the engineering field as concrete and steel. But bringing a firm into the information age can be complicated and expensive....

The NOAA Restoration Center: Next Steps
The National Oceanic and Atmospheric Administration (NOAA) Restoration Center (RC) was founded in 1991. Since its inception it has made significant progress along several fronts. Foremost,...

NOAA's Damage Assessment Center
