The CubeSail is a nano-Solar Sail based on the 3U CubeSat standard currently being built at the Surrey Space Centre. The CubeSail mission aims to demonstrate the concept of solar sailing and at its end-of-life use the sail membrane for de-orbiting. One of the main challenges in the design of any Solar Sail is the deployment mechanism. This paper proposes a deployment mechanism for the CubeSail....

Abstract Debt overhang is associated with higher financial fragility and slower recovery from recession. However, while household credit booms have been extensively documented to this property, we find that corporate debt does not fit the same pattern. Newly collected data on nonfinancial business liabilities for 18 advanced economies over past 150 years shows that, in aggregate, greater fricti...

Abstract We investigate how the economy responds to anticipated (news) shocks future investment decisions. Using structural vector autoregressions (SVARs), we show that news about relative price of residential explains a high fraction variance output, aggregate and for Spain. In contrast, Germany it is on business structures equipment explain higher consumption non-residential investment. confr...

NASA Tech Briefs, March 2010 Inflatable tubular structures that have annular cross sections rigidized with foams, and the means of erecting such structures in the field, are undergoing development. Although the development effort has focused on lightweight structural booms to be transported in compact form and deployed in outer space, the principles of design and fabrication are also potentiall...
