C0 Fixed Degrees of Freedom Zigzag Model with Variable In-Plane and Out-of-Plane Kinematics and Quadrilateral Plate Element
(American Society of Civil Engineers, 2015)Physically based, multilayered zigzag models have the merit of providing accurate stress predictions with few fixed unknowns, but unfortunately they involve derivatives of functional degrees of freedom (e.g., -
Cable Structures and Lunar Environment
(American Society of Civil Engineers, 1992)Lunar environmental characteristics, such as the lack of atmosphere, the smaller gravitational acceleration, and the weaker regolith, place different requirements on structural systems than the earth environment does. Some ... -
Cable‐Based Lunar Transportation System
(American Society of Civil Engineers, 1994)The establishment of an efficient transportation system is key to any human development on Earth or in space. Different technologies for transporting humans and goods have been developed, the diversity of which indicates ... -
Calculation of Structural Response and Response Sensitivity with Improved Substructuring Method
(American Society of Civil Engineers, 2019)Structural responses and response sensitivities are frequently required in structural health monitoring, whereas the computation of structural responses and response sensitivities of a large-size model is time consuming. ... -
Calibration of Strapdown Magnetometers in Magnetic Field Domain
(American Society of Civil Engineers, 2006)This paper presents an algorithm for calibrating strapdown magnetometers in the magnetic field domain. In contrast to the traditional method of compass swinging, which computes a series of heading correction parameters and ... -
Capacitive Micromachined Ultrasonic Transducers: Theory and Technology
(American Society of Civil Engineers, 2003)Capacitive micromachined ultrasonic transducers (CMUTs), introduced about a decade ago, have been shown to be a good alternative to conventional piezoelectric transducers in various aspects, such as sensitivity, transduction ... -
Car-Top Test Module as a Low-Cost Alternative to Wind Tunnel Testing of UAV Propulsion Systems
