The Ontogeny of Escape Responses and Locomotor Performance in Sceloporus Woodi
… = 3.32, P = 0.047). Larger animals did not allow close approach of a human predator presumably escaping early and to avoid the need to use high sprint velocities to escape. Smaller lizards, due to slower sprint velocities, must use behavior to compensate for decreased sprint velocity. Small …

Predicting and identifying signs of criticality near neuronal phase transition
… focusing on stochastic subthreshold dynamics on close approach to spiking and to depolarisation-blocked quiescence (spiking death) transition points. Theoretical analysis of subthreshold neural behaviour then shifts to the anaesthetic-induced phase transition into unconsciousness using a …

Spectral mapping and long-term seasonal evolution of Pluto
… exploration, a study of Apophis during its 2029 close approach to Earth. Since the earlier portion of this thesis focused on the encounter, data collection, and scientific analysis portion of a spacecraft mission (New Horizons), we go full circle by exploring the early stage of the

Autonomous orbital rendezvous using angles-only navigation
… navigation performance for rendezvous and close approach applications where on-board navigation must be accomplished through the use of angles-only measurements by developing various relative motion orbital trajectories. Chaser vehicle maneuvers designed to enhance the estimator's …

Multiple Asteroid Retrieval Mission
… ecliptic plane and returned to L2-Halo with two approaches, MARM-1 and MARM-2. Together, these databases provide all information for every asteroid's close approach known today. Returning the asteroid as a whole is explored in the MARM-1 method, while MARM-2 evaluates the possibility of reaching …

PLATE HEAT EXCHANGER IMPROVEMENTS WITH SHAPE OPTIMIZATION
… due to their compactness, flexible sizing, close approach temperature, and good heat transfer performance. PHXs are increasingly utilized and becoming very competitive in two-phase flow applications due to their desirable thermal-hydraulic characteristics. Pillow plate heat exchanger (PPHX) …

Hydrolysis of aluminum in synthetic cation exchange resins and dioctahedral vermiculite
… a portion of the water was centrally located. A close approach between the remainder of the water and the basal oxygens was the assumption required to explain the observed intensities. The aluminum saturated dloctahedral vermiculite (14.91 A) was observed to collapse in a random interstratified …
