A Distributed Genetic Algorithm With Migration for the Design of Composite Laminate Structures
(Virginia Tech, 1998-08-05)
This thesis describes the development of a general Fortran 90 framework for the solution of composite laminate design problems using a genetic algorithm (GA). The initial Fortran 90 module and package of operators result ...
The Analysis and Creation of Track Irregularities Using TRAKVU
(Virginia Tech, 1998-06-30)
The accuracy of the results from a rail vehicle dynamic model is dependent on the realism of the track input to the model. An important part of the track input is the irregularities that exist on actual track. This study ...
Examination of Driver Lane Change Behavior and the Potential Effectiveness of Warning Onset Rules for Lane Change or "Side" Crash Avoidance Systems
(Virginia Tech, 1997-03-27)
Lane change or "Side" Crash Avoidance Systems (SCAS) technologies are becoming available to help alleviate the lane change crash problem. They detect lane change crash hazards and warn the driver of the presence of such ...
