Design, analysis and evaluation of bridge superstructures for live loads

Creator:

Turan, O. Tugrul

Abstract:

Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...

Optimal soaring by a small autonomous glider

Creator:

Kyle, Jason A.

Abstract:

Extending the flight time of an autonomous unmanned air vehicle by soaring is considered. A suboptimal controller is developed and successful static soaring is demonstrated with a 6 degree of freedom glider model. Altitude gain rates of between ¼ and ½ m/s are achieved with this simple implementation. A hybrid...

On the design, modeling, and testing of ocean wave energy converters

Creator:

Bosma, Bret

Abstract:

Ocean wave energy converter technology continues to advance and new developers continue to emerge, leading to the need for a general design, modeling, and testing methodology. This work presents a development of the process of taking a wave energy converter from a concept to the prototype stage. A two body...
