Concurrent Engineering Planning in HSGT Systems
Why should concurrent engineering concepts and TQM (Total Quality Management) procedures be considered for large scale HSGT (High Speed Ground Transportation) engineering and planning...

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...

Aerodynamic Resistance of Trains Running Through a Tunnel
In what follows, some previously published results and formulae have been combined in order to obtain an applicable tool for evaluating the energy consumption of trains in tunnel as a...

The Use of Multibody Software in the Wheel/Rail Contact as Applied to Very High Speed Tests
How strange may it be, the behaviour of railway vehicles depend on contact forces developing between wheels and rails inside patches of no more than 1 cm²....

Assessment of Guideway Systems for Maglev Applications
Recognizing the potential benefits of MAGLEV high speed mass transportation systems, three innovative guideway systems have been evaluated herein from the viewpoint of: (1) loads and performance...

Cable-in-Conduit Superconductors for MAGLEV Magnet Systems
A major advantage of using a Nb₃Sn Cable-in-Conduit Conductor (CICC) for MAGLEV lies in its demonstrated capability to operate in supercritical helium....

Preliminary Test Planning for the National Maglev Initiative
This paper describes the effort undertaken as part of the National Maglev Initiative to identify, document, and analyze the following maglev system aspects: architecture, operational concepts,...

Building a Viable Maglev Industry
Transforming the chaotic fragmentation of competing and incompatible magnetic levitation systems into a robust and expanding U.S. industry will provide substantial benefits to established...

Plan for Development and Implementation of a Domestic Maglev Network
This paper discusses magnetic levitation (maglev) transportation technical requirements and methods of capturing associated requirements. Possible architectures and components of a domestic...

Planning a Nationwide High Speed Rail Freight and Passenger Network
Planning for high speed rail networks is better done at the national level when considering widespread public benefits of these networks, and is essential when dealing with institutional...

The Transrapid Maglev System
The Transrapid 300 mph (500 km/hr) magnetically levitated transportation system is ready for revenue application and is under consideration for several sites in the U.S. The maglev system...

Knolle Magnetrans: A Magnetically Levitated Train System
New permanent magnet materials can now withstand repulsion indefinitely without loss of magnetism. Vehicular magnetic levitation occurs when a track and the undersides of vehicles thereon...

Colorado Dome
Innovative engineering and precise design helped engineers overcome a building's unique shape and difficult site to deliver the $71.5 million Jefferson County Government Center...

Coastal Erosion and Protection in China
The recent coastal erosion in China was becoming increasingly remarkable in the late fifties and had taken a turn for the worse in the late seventies. At present there exist about 70 per...

Meteorological Forcing on Louisiana Wetlands
The open wetland areas of southern Louisiana are vulnerable to meteorological forcing. On the basis of over one year U.S.G.S. funded measurements of atmospheric pressure, air-sea temperature...

Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...

Consolidation Settlement Potential in South Louisiana
Primary consolidation is an important cause of wetland loss in active and recently abandoned deltaic plains in south Louisiana. Argillaceous and organic facies are most subject to reduction...

Dealing with TMDLs in the Dairy-McKay HUA
The maximum phosphorus concentration for the TMDL in the Tualatin River is set by Oregon Administrative Rules (OAR) at 0.07 mg/1, Dairy-McKay Creek is 0.045 mg/1 Identification of potential...

Marina Facilities Planning Design and Operations in Hurricane Prone Areas
The overall growth in population of coastal areas in the southeastern and coastal regions of the Unites States has created a need for additional water related recreation facilities such...

Anthropogenic Activities Affecting Sediment Load Balance Along the West African Coastline
The west African coastline stretches from Senegal in the west-to Cameroon in the east. This coastline had naturally over time received most of its sediments through the numerous rivers...
