In this paper we propose a successive convexification (SC) algorithm suitable for real-time
guidance applications of the fuel-optimal powered landing problem with aerodynamic drag …

BACKGROUND AND PURPOSE: Prior studies of radiologic superior semicircular canal
dehiscence have suggested that CT may overcall dehiscence. However, many of those studies …

A 14 week undergraduate course on laboratory safety was developed at the University of
Pittsburgh. The first segment of the course consists of a series of lectures intended to increase …

Dropout remains a persistent challenge within high school education. In this paper, we
present a case study on automatically detecting whether a student is at-risk of dropout within a …

Although there is much interest in behavioral syndromes, very little is known about how
syndromes are generated in wild populations. Here, we assess the roles of correlated selection …

Precopulatory sexual cannibalism may represent the most extreme form of sexual conflict

Near Rectilinear Halo Orbits (NRHOs), a subclass of halo orbits around the L1 and L2
Lagrange points, are promising candidates for future lunar gateways in cis-lunar space and as …

A robust drift-safe rendezvous trajectory optimization tool is developed in this work, with
applications to orbital rendezvous and proximity operations. The method is based on direct …
