Hierarchical carbon nanotube forests and applications
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Carbon nanotube (CNTs) are allotropes of carbon with a cylindrical nanostructure. Very different from other materials, CNTs show a great value for ...
Skydiving control system
(University of Missouri--Columbia, 2015)
Skydiving, the act of a person jumping out of an airplane (or aircraft) and landing safely on the ground, has been a common practice since the early 1900's. Throughout the history of skydiving, skydivers have used parachutes ...
Prediction of surface roughness and diameter deviation in drilling ti-6al-4v alloy using artificial neural networks and Taguchi's design of experiments
(University of Missouri--Columbia, 2015)

Wettability and nanostructure effect on oscillating heat pipes
(University of Missouri--Columbia, 2015)
As electronics technologies rapidly develop with a demand for more power and miniaturization, effective thermal management of these systems becomes much more important. The oscillating heat pipe (OHP) is a promising highly ...
Flooded two-phase flow dynamics and heat transfer with engineered wettability on microstructured surfaces
(University of Missouri--Columbia, 2015)
Due to excessive droplet feeding, a period of flooding occurs as part of a typical droplet based thermal management cycle. The conventional superhydrophilic surface, which is designed for thin film evaporation because of ...
Design, analysis and dynamic phenomena of MEMS capacitive power harvester
(University of Missouri--Columbia, 2015)
Unwanted vibrations are all around us in our daily life. These vibrations can effectively be converted into electrical power through capacitive device. Even though the amount of power generated is small ([mu]W), it is still ...
Cruise flight optimization of a commercial aircraft with winds
(University of Missouri--Columbia, 2015)
With high prices for fuel and airfare, companies are looking to minimize operational costs. Reducing aircraft fuel consumption is one strategy companies use to lower costs. During flights, commercial aircraft divide the ...
Superharmonic Responses of an Oscillator with Impact
