Properties of Bottom Ash-Based Composite
High-calcium bottom ash, a by-product of the electric power industry, was evaluated for feasibility of use as a fine aggregate in structural grade concrete. Both fresh and hardened properties...
Digital Image Processing: Experiences in the Gulf War
During the 1990-91 conflict in Southwest Asia between Iraq and coalition forces operating with US Armed Forces, the utility of products developed from digital imagery and digital terrain...
Morphological Methods for Characterizing Inter-feature Distances
Characterizing inter-feature distances in digital images using automatic image analysis systems presents problems not found when quantifying the morphology of the features themselves....
Multi-Paradigm Learning Algorithms for Image Recognition
Several recently-developed machine learning algorithms for the image recognition problem are reviewed. They are based on adroit integration of various recent and emerging technologies...
Image Analysis of Clay Microstructure
The paper summarises new methods which have been developed to analyse oriented textures in electron micrographs of clay soils, complementary methods using polarising microscopy, and an...
Digital Evaluation of Contaminated Sites
This paper introduces digital techniques to evaluate historical maps and aerial photographs in order to detect contaminations on derelict industrial sites. Special attention is paid to...
Survey of Image Processing Applications in Civil Engineering
A number of imaging products have been developed for civil engineering applications. This paper attempts to survey various image processing applications in civil engineering up to date....
Computer Vision Techniques for Comparing Laser Doppler Velocimeter Scans of a Vibrating Plate to Analytical Plate Modes
Computer vision procedures were applied to velocity images of a vibrating square steel plate. A scanning laser Doppler velocimeter (LDV) measured the images of low frequency resonant operating...
Optimal Region Aggregation with Shape Considerations in Spatial Optimization
The region aggregation (land acquisition) problem is discussed within the context of a regular grid matrix having representative cell indices or attribute values. Several optimization...
An Introduction to APM Systems and Applications
An Automated People Mover (APM) is an advanced transportation system in which automated driveless vehicles operate on fixed guideways in exclusive rights-of-way. These differ from other...
A Marketing Analysis of an Old Concept: the Horizontal Elevator-Monorail
The objective of this research is to define an efficient and cost effective concept for an Automated People Mover (APM) System. Current solutions are relatively expensive to install, have...
A Vision for 21st Century Guided Transit
The design characteristics for 21st century fixed guideway transit are discussed. A system concept responsive to passengers' needs is envisioned. The concept ignores traditional boundaries...
Active Guideway Systems
Many automated people movers which have been developed or studied in France or in other countries belong to the category of active guideway systems. This paper describes characteristics...
Comparative Analysis of Different Systems for a New Rail Line in Copenhagen, Denmark
A new Mass Transit System is to be built in Copenhagen, Denmark. The Copenhagen Public Bus Company, HT, and the Danish State Railways, DSB, have each carried out feasibility studies. Conventional...
Technological Innovations: Opportunities to Reduce Costs
This paper presents a comparative study of an automatic dedicated single track people mover and an automatic dedicated double track people mover. The study examined both `system' and infrastructure...
Integrating Waiting Time in the Design of a Transportation System for Short to Intermediate Distances
This paper addresses passenger perceptions of short to medium distance public transportation systems. The concept of the weighted total transportation time (WTTT) is introduced, integrating...
A Public Transport System Based on Light Electric Cars
This paper presents the concept under development in France of a novel transportation system based on fleet of small public cars under supervision from a central computer. These public...
Concept of a Polycentric Metropolitan Area with Automated People-Movers
The general equation of mobility is used to understand the development of urban systems. Using iterative methods it is shown that the town planning criterion used currently gives rise...
