Design of Flight Control Laws for a Novel Stratospheric Dual-Aircraft Platform
… systems (UAS) tethered via a thin adjustable cable allowing them to sail back-and-forth, without propulsion, using vertical wind shear. DAP offers the potential of a low-cost atmospheric satellite. This thesis presents the results of an initiative to demonstrate this novel flight concept …

State and Dynamics Estimation in an Outdoor Multi-Drone Slung Load System
… attached to one or more drones using a flexible cable can significantly enhance the capabilities of these platforms. This work aims to develop a multi-drone platform, built on open-source tools such as PX4 and ROS2, that can be used to lift a general slung load in an outdoor environment. Various …

Investigation of the dynamic behavior of a cable-harnessed structure
… the author investigates the effects of adding cables to a simple structure with the goal of developing an understanding of how cables interacting with a structure. In this research, the author presents predictive and accurate modeling of a cable-harnessed structure by means of the Spectral …

The dynamics of geometrically compliant mooring systems
… employed for the temporal integration of the cable dynamics equations, including box method, trapezoidal rule, backward differences, and Newmark’s method, the generalized-a algorithm has the advantages of second-order accuracy, controllable numerical dissipation, and improved stability when …

Modeling Cable Harness Effects on Space Structures
Due to the high mass ratio of cables on lightweight spacecraft, the dynamic response of cabled structures must be understood and modeled for accurate spacecraft control. Models of cable behavior are reviewed and categorized into three major classes consisting of thin rod models, semi-continuous …

Actin Cable Function and Regulation in the Budding Yeast, Saccharomyces cerevisiae
… chapters, I describe factors underlying actin cable dynamics and assembly in the budding yeast, S. cerevisiae. First, I examined the role of type II myosin and a tropomyosin isoform in retrograde actin flow (Chapter II). In yeast and other cell types, actin undergoes retrograde or centripetal …

Dynamics and Control of Very High Altitude Tethered Balloons
… are expected to have an impact on the system’s dynamics and therefore its technical feasibility. An operational altitude of 20km is recommended for this application, which makes it the largest scale tethered aerostat considered to date. A hollow pipe-like tether is required for the …
