Patent number: 8175855Abstract: A method and system for predicting the quality factor of a mechanical resonant (MR) device. The system and method simulates uncoupled elastic vibration of the MR device to produce simulated dilatation and collects data relating to the dilatation and maximum stored elastic vibration energy. It determines the internal heat source data of the MR device caused by dilatation based on the thermal expansion effect of the MR device material, conveying the internal heat source data along with transient heat conduction data to a simulation engine, which simulates and determines the temperature variation. Thermoelastic damping over one cycle of vibration is determined, enabling the prediction of the quality factor relating to thermoelastic damping over one cycle of vibration of the MR device, and the maximum elastic vibration energy stored over one cycle of vibration.Type: GrantFiled: August 7, 2008Date of Patent: May 8, 2012Assignee: Old Dominion University Research FoundationInventor: Zhili Hao

Publication number: 20110292208Abstract: A method, system, and computer readable medium for producing orthoimages of the images of a (typically) high-resolution imager of an urban area, the orthoimages of high buildings being imaged with improved accuracy by increasing constraint conditions on the building edges, such as perpendicularity, collinearity. These constraint conditions are merged into an orthorectification model for orthorectifying the images captured at a predetermined elevation, whether by airborne or spaceborne. Constraint conditions may be formed by the building edge points, such as corners, and may be used with a digital building model. Thus, an aspect of embodiments is that the constraint conditions may be directly formed from the building themselves. The higher the buildings, the more effective the constraint controls.Type: ApplicationFiled: November 23, 2010Publication date: December 1, 2011Applicant: Old Dominion University Research FoundationInventors: Guoqing Zhou, Wenhan Xie
