Abstract: A form of Lagrange’s equations in terms of quasi-coordinates (Boltzmann/Hamel equations) is presented. Identities are introduced which permit a straightforward method for formulating the equations ...

Abstract: This paper presents an experimental study of a tracking control of a shape memory alloy (SMA) wire actuator using a nonlinear robust compensator. The control design uses the sliding-mode approach ...

Abstract: The analytical approaches developed in a companion paper (Part I) were used to quantify the relationship between fine-pointing control and thermal loading of the aperture plate. Dynamic simulations ...

Abstract: The dynamic equations for the simulation of Space Station Freedom configured with solar dynamic (SD) power modules are developed. The formulation permits the structure to be subjected to shuttle ...

Abstract: The vibration of large turbomachinery blading is well known to be one of the most important design factors in modern turbomachinery. Typically, blade vibration is dominated by the unsteady flow ...

Abstract: One of the most important design factors in modern turbomachinery is the vibration of turbomachinery blading. There is a need for developing an in-service, noncontacting, noninterfering method ...

Abstract: A device reminiscent of the mammalian spine has been designed and built with the ability to lock each individual joint in a string of ball joints. The assembly may be controlled in a manner ...

Abstract: Recent studies have demonstrated some advantages of using advanced heuristic algorithms to identify near-Pareto-optimal future locations, types, and sizes for stormwater low-impact development and green infrastructure ...

Abstract: The effectiveness of a cardiovascular stent depends on many factors, such as its ability to sustain the compression applied by the vessel wall, minimal longitudinal contraction when it is ...
