Bulletproof gossamer : spinning a superfiber
Spider silk is a material of extraordinary beauty and utility. From the spider's perspective, it is foremost a building material, but also a safety net, a sensory organ, a weapon. From a human perspective, it is a material of extraordinary mechanical properties, an object of artistic and cultural …

Active Dynamic Analysis and Vibration Control of Gossamer Structures Using Smart Materials
… inflatable structures, otherwise known as gossamer structures, are smaller, lighter, and more flexible than current satellite technology. Unfortunately, little research has been performed investigating cost effective and feasible methods of dynamic analysis and control of these structures …

Towards Structural Health Monitoring of Gossamer Structures Using Conductive Polymer Nanocomposite Sensors
… a structural health monitoring algorithm for gossamer structures by using nanocomposites as strain sensors. Any health monitoring system works on the principle of sensing the response (strain, acceleration etc.) of the structure to an external excitation and analyzing the response to find out …

Technoeconomic Assessment of a Gossamer, Planar, Gigawatt-Scale Space-Based Solar Power System
This thesis aims to analyze space-based solar power (SBSP) from both technical and financial standpoints. While the analysis is mainly purposed to validate the findings of existing literature on SBSP, it also seeks to identify the problems that need to be addressed for SBSP to become technically …

Delegation for Multi-Threaded and Rack-Scale Software
… settings. We present two system, Trust and Gossamer, to demonstrate the versatility of this approach across different domains. Trust introduces a type- and memory-safe alternative to traditional locking in concurrent programs. Instead of synchronizing multi-threaded access to an object of …

Modeling and Control of Tensegrity-Membrane Systems
… candidates for lightweight space structures and gossamer spacecraft. In this dissertation, modeling and control of tensegrity-membrane systems is studied. A systematic method is developed to determine the equilibrium conditions of general tensegrity-membrane systems. Equilibrium conditions can be …

Maison de Couture
… of conventional methods and projections. The gossamer like screen prints serve as cameras into the world within the Maison de Couture. They capture the essence of the creative process, always-in-motion spirit of a fashion house. The architectural projections describe the architectural skeleton …

Finite Element Modeling and Active Control of an Inflated Torus Using Piezoelectric Devices
… satellites, inflatable structures, also known as gossamer structures, are being considered. Inflatable space-based structures are susceptible to vibration disturbance due to their low stiffness and damping. This thesis discusses the structural dynamics and vibration suppression via piezoelectric …

International water law and the quest for common security
… management. Given the fact that water is the gossamer linking various other security issues – e.g., energy, food and environment – it seems obvious that ‘business as usual’ in transboundary water management will threaten future global stability and endanger the very foundation of international …

Documenting the Patterns and Ecological Impacts of a Densovirus on Melissa Blue Butterflies (Lycaeides melissa) and Beyond
… in wild-caught members of the Lycaenidae family (gossamer-winged butterflies). I found spatial variation of JcDV prevalence across sites of L. melissa , which suggests that viral exposure is different across populations and JcDV may be endemic in some. There was considerable variation in viral …

Dynamics and Control of a Pressurized Optical Membranes
Optical membranes are currently pursued for their ability to replace the conventional mirrors that are used to correct wave front aberration and space-based telescopes. Among some of the many benefits of using optical membranes, is their ability to considerably reduce the weight of the structure. …
