So far this report has discussed the choices available for digital preservation very much in the sense of forward planning—following a set of logical, ordered steps in order to ensure the preservation of digital material. However, this is not always possible. What if one, or more, of these steps has been omitted? Documentation may be missing. Copying, refreshing or routine back-ups may not have...

Carsharing operators, which rent out electric vehicles for minutes or hours, lose money on idle vehicles. We develop a model that allows carsharing operators to offer the storage of these vehicles on operating reserve markets (market for quickly rampable back-up power sources that replace for instance failing power plants). We consider it a dispatch and pricing problem with the tradeoff between...

Abstract. Work of Dolgachev and Castravet-Tevelev establishes a bijection between the 2 weights of the half-spin representations of so2n and the generators of the Cox ring of the variety Xn which is obtained by blowing up P n−3 at n points. We derive a geometric explanation for this bijection, by embedding Cox(Xn) into the even spinor variety (the homogeneous space of the even half-spin represe...

There are a large number of tools that can be utilized to forecast fog. Some of the tools were described in the paper “ Radiation Fog: UPS Airlines Conceptual Models and Forecast Methods” (Baker, et al., 2002). Several modules were also developed in the Distance Learning Aviation Course in 2004 which summarized a list of fog forecasting tools (UCAR, 2001). This paper will demonstrate the use of...

air, and nonequilibrium air solutions to sharp cones and a sharp wedge were obtained as check cases for the UPS code. The integrated LAURA-UPS procedure is demonstrated for two slender blunted-cones. Heating rates are presented on an 8-deg sphere-cone in Mach 5 and perfect gas at 0and 4-deg angles of attack and on the Reentry-F body at Mach 20, 80,000 ft. equilibrium gas conditions for 0and 0.1...

We investigate systems of self-propelled particles with alignment interaction. Compared to previous work (Degond and Motsch, Math. Models Methods Appl. Sci. 18:1193–1215, 2008a; Frouvelle, Math. Models Methods Appl. Sci., 2012), the force acting on the particles is not normalized, and this modification gives rise to phase transitions from disordered states at low density to aligned states at hi...

Underground pedestrian systems (UPS) have been developed worldwide especially in the central areas of mega cities. They are integrated with subway systems, underground shopping streets and malls, and the basement of department stores in various forms and integrated with commerce, transport, retailing and public usage in urban functions. In cities with severe weather conditions such as Toronto a...

This paper provides an overview and interpretive analysis of the Japanese strategic alliance process. Both international and domestic alliances are considered, although the emphasis is on domestic partnerships. I argue that the domestic Japanese economy is "underallianced" relative to Japanese firms' extensive involvement in partnerships with foreign firms. This is particularly true if governme...

We model financial market liquidity as provided by financially constrained arbitrageurs. Market liquidity increases with the level of arbitrage capital, i.e., internal and external capital arbitrageurs can access frictionlessly. We show that liquidity dry-ups follow periods of low returns of arbitrageurs’ risky investment opportunities, and that liquidity is correlated across markets. A welfare...
