Wall Modeled Large Eddy Simulation of Flow over a Wall Mounted Hump
(Virginia Tech, 2014-07-02)
Large Eddy Simulation (LES) is a relatively more accurate and reliable alternative to solution of Reynolds Averaged Navier Stokes (RANS) equations in simulating complex turbulent flows at a lesser computational cost than ...
Validating Teamology in Domestic and International Setting
(Virginia Tech, 2015-12-14)
In recent years, collaboration between different companies especially global collaboration on oversea product development becomes more and more popular. Forming efficient product design team becomes an important concern ...
A Model For The Absorption Of Thermal Radiation By Gold-Black
(Virginia Tech, 2015-10-29)
The work presented here addresses an important topic in thermal radiation detection when gold-black is used as an absorber. Sought is a model to simulate the absorption of thermal radiation by gold-black. Fractal ...
Smart Power Module for Distributed Sensor Power Network of an Unmanned Ground Vehicle
(Virginia Tech, 2014-07-25)
Energy efficiency is a driving factor in modern electronic design particularly in power conversion where conversion losses directly set the upper limit of system efficiency. A wide variety of commercially available DC-DC ...
Development and Characterization of an Interprocess Communications Interface and Controller for Bipedal Robots
(Virginia Tech, 2016-01-18)
As robotic systems grow in complexity, they inevitably undergo a process of specialization whereby they separate into an array of interconnected subsystems and individual processes. In order to function as a unified system, ...
Low Frequency Noise Reduction Using Novel Poro-Elastic Acoustic Metamaterials
(Virginia Tech, 2014-06-04)
Low frequency noise is a common problem in aircraft and launch vehicles. New technologies must be investigated to reduce this noise while contributing minimal weight to the structure. This thesis investigates passive and ...
Force Feedback for Reliable Robotic Door Opening
(Virginia Tech, 2015-09-09)
Opening a door is still a hard problem in robotics. Many robotic manipulators use open-loop position control to open doors, which reduces reusability and reliability in the face of slight differences or sensor errors. Many ...
Model Reference Adaptive Backstepping Control of an Autonomous Ground Vehicle
(Virginia Tech, 2016-01-27)
With an increased push for commercial autonomous cars, the demand of high speed systems capable of performing in unstructured driving environments is growing. In this thesis, the behavior of a bio-inspired predator prey ...
The measurement of the running torque of oil and grease lubricated instrument ball bearings under combined radial and axial loads
(Virginia Polytechnic Institute, 1966)
The use of chemiluminesence for light-off detection of flames
(Virginia Polytechnic Institute and State University, 1989)
