Flying Qualities Specifications and Design Standards for Unmanned Air Vehicles
Autor: M. Christopher Cotting, John R. Leonard, Daniel J. King, Jessica Holmberg
Publikováno v: AIAA Atmospheric Flight Mechanics Conference and Exhibit.
An increasing number of unmanned air vehicle (UAV) systems are being developed for use by the U.S. Navy and Marine Corps. The adequate design and development of UAV platforms is crucial to future fleet operations. Flying qualities standards and crite

Hybrid Robust Control and Reinforcement Learning for Optimal Upset Recovery
Autor: Neha Gandhi, David G. Ward, Nathan D. Richards, Brian Dutoi, John R. Leonard
Publikováno v: AIAA Guidance, Navigation and Control Conference and Exhibit.
Air safety and flight asset protection benefit greatly from rapid upset recovery. Autonomous recovery is of particular interest due to a recent significant increase in fielded Unmanned Aerial Vehicles (UAVs). Autonomous recovery challenges include co

Cerebral dynamic studies for early detection of recurrent anaplastic intracranial gliomas
Autor: Jack K. Goodrich, John R. Leonard, C. Craig Harris, M. S. Mahaley, Lynn R. Witherspoon, J. Wendell Tyson
Publikováno v: Journal of Neurosurgery. 43:142-149
✓ The authors compared radionuclide cerebral dynamic studies, brain scans, and clinical evaluation as indicators of recurrence of intracranial anaplastic gliomas and found cerebral dynamic studies more sensitive to tumor growth than static brain sc

A sea bottom multichannel hydrophone array
Autor: Peter W. Carter, M. C. Sinha, John R. Leonard, Christine M. R. Powell
Publikováno v: Marine Geophysical Researches. 8:277-292
The PUMA (Pull-Up Multichannel Array) is a sea-bottom instrument for remotely recording data from a 12 channel hydrophone array. Its purpose is to achieve (i) denser data coverage, leading to (ii) improved velocity analysis and (iii) multichannel pro

Cytologic results of fine-needle aspiration biopsies of the central nervous system
Autor: Ira M. Hardy, John R. Leonard, Robert L. Timmons, H. Thomas Norris, Jan F. Silverman, Lawrence S. Harris, Kevin O'Brien
Publikováno v: Cancer. 58:1117-1121
The cytologic results of 34 fine-needle aspiration (FNA) biopsies of the central nervous system (CNS) are reported. There were 31 intraoperative biopsies performed at the time of craniotomy. All the cases were diagnosed using direct smear preparation

Characterization of Malignant Gliomas and Cerebrovascular Disease by Cerebral Dynamic Studies
Autor: Jack K. Goodrich, M. S. Mahaley, R. S. Preissig, John R. Leonard, C. Craig Harris, Lynn R. Witherspoon, J. Wendell Tyson
Publikováno v: Stroke. 6:199-205
A technique for analysis of dynamic radionuclide studies of the cerebral circulation is described. This technique permits objective classification of observed radionuclide distribution patterns. Variation in the time-to-peak activity, and in the maxi

Multiple subdural hematomas associated with breakdancing
Autor: Stephen L McNeil, J Ross Shuping, Ricky L. Langley, John R Leonard, W Austin Spruill
Publikováno v: Annals of Emergency Medicine. 16:114-116
A 17-year-old, previously healthy, male breakdancer presented with a three-month history of crescendo headache and newly identified papilledema. The patient was found to have four separate, unilateral extracranial collections. At surgery, three were
