Neural network aided aviation fuel consumption modeling
(Virginia Tech, 1997-08-25)
This thesis deals with the potential application of neural network technology to aviation fuel consumption estimation. This is achieved by developing neural networks representative jet aircraft. Fuel consumption information ...
A Method to Enhance the Performance of Synthetic Origin-Destination (O-D) Trip Table Estimation Models
(Virginia Tech, 1997-06-09)
The conventional methods of determining the Origin-
Destination (O-D) trip tables involve elaborate surveys,
such as home interviews, requiring considerable time,
manpower and funds. To overcome this drawback, a number ...
Investigation Into Snap Loading of Cables Used in Moored Breakwaters
(Virginia Tech, 1999-11-18)
A two-dimensional, nonlinear dynamic analysis is conducted on a moored breakwater
configuration to investigate snap loads in mooring lines. Breakwaters are structures used
to attenuate or eliminate waves and protect ...
Modeling Aircraft Fuel Consumption with a Neural Network
(Virginia Tech, 1997-02-07)
This research involves the development of an aircraft fuel consumption model to simplify Bela Collins of the MITRE Corporation aircraft fuelburn model in terms of level of computation and level of capability. MATLAB and ...
A Methodology for Estimating the Level of Aggressiveness in Competitive Bidding Markets
(Virginia Tech, 1999-12-09)
Competitive bidding, where the project is awarded to the lowest bidder, is a basic part of the construction industry. This method of project delivery is designed to promote healthy competition in an attempt ensure the ...
Feasibility Study of Partially Restrained Connections
(Virginia Tech, 1997-02-10)
In recent years the idea of using partially restrained connections in building structures has become more practical and economical. Partially restrained connections resist moment and also allow rotation, therefore distributing ...
Two-Dimensional Analysis of Stacked Geosynthetic Tubes
(Virginia Tech, 1998-11-02)
Geosynthetic tubes filled with a slurry-mix are considered. The mix is usually dredged from a nearby area and pumped directly into the tubes. The tubes are used in a variety of applications including breakwaters, groins, ...
The Effect of Adhesion on the Contact of an Elastica with a Rigid Surface
(Virginia Tech, 1999-12-08)
The understanding of topics such as friction, wear, lubrication, and adhesive bonds is dependent on the ability to measure surface and interfacial energies. The surface energies of liquids may be measured accurately using ...
Analysis of Pressurized Arch-Shells
(Virginia Tech, 1998-11-19)
A pressurized arch-shell structural component made of flexible material is considered.
The component is inflated with high internal pressure. The behavior of similar types
of structures, such as a pair of leaning pressurized ...
Development and Testing of a Capacitor Probe to Detect Deterioration in Portland Cement Concrete
(Virginia Tech, 1998-09-07)
Portland cement concrete (PCC) structures deteriorate with age and need to be maintained or replaced. Early detection of deterioration in PCC (e.g., alkali-silica reaction, freeze/thaw damage or chloride presence) can ...
