Astronaut Extravehicular Activity : safety, injury & countermeasures; &, Orbital collisions & space debris : incidence, impact & international policy
(Massachusetts Institute of Technology, 2010)Extravehicular Activity (EVA) spacesuits are a key enabling technology which allow astronauts to survive and work in the harsh environment of space. Of the entire spacesuit, the gloves may perhaps be considered the most ... -
Astronaut-centric analysis of a jetpack with integrated control-moment gyroscopes for enhanced extravehicular activity performance
(Massachusetts Institute of Technology, 2014)As a stepping-stone towards eventual human exploration of Mars, NASA plans to explore low-gravity objects. Since the surface environments encountered on such missions would limit the independent mobility of astronauts, a ... -
Astronomical studies of solar system bodies 2060 Chiron and 1 Ceres
(Massachusetts Institute of Technology, 2013)In this thesis two separate projects are investigated, a stellar occultation by 2060 Chiron and rotationally resolved spectra of 1 Ceres. On 29 November 2011 UT, 2060 Chiron occulted a 14-mag star; data were successfully ... -
Astrophysical applications of the Einstein ring gravitational lens, MG1131+0456
(Massachusetts Institute of Technology, 1995) -
Astrophysical signatures of neutron stars in compact binaries and experimental improvements on gravitational-wave detectors
(Massachusetts Institute of Technology, 2019)Neutron stars (NSs) are astrophysical laboratories that allow us to probe physics at extreme conditions. The first half of this Thesis is devoted to exploring how we can connect theoretical models of NSs to observational ... -
An asylum : design specificity for the spectrum of cognitive conditions
(Massachusetts Institute of Technology, 2013)This thesis seeks to re-engage the intimate connection between architecture and the minds of its inhabitants through design that addresses specific cognitive needs. Architecture fundamentally shares a connection with the ... -
Asymmetric hydrogenation of unfunctionalized trisubstituted and tetrasubstituted olefins
(Massachusetts Institute of Technology, 1998)A highly reactive chiral catalyst for the asymmetric hydrogenation of aryl trisubstituted olefins was generated by combining the complex (EBTHI)MMe2 (EBTHI = ethylenebistetrahydroindenyl, M = Ti, Zr) with [PhMe2NH]+[(BC6F5)4]- ... -
Asymmetric information, exchange rate uncertainty and banking competition
(Massachusetts Institute of Technology, 1997) -
Asymmetric intramolecular Diels-Alder reactions
(Massachusetts Institute of Technology, 1986) -
Asymmetric network ties to elite American universities create differential access to venture capital in Africa
(Massachusetts Institute of Technology, 2022-09)Why is the venture capital (VC) flowing into Africa concentrated in a handful of countries? I reject the popular notion that market size is the primary reason why VC investments only end up in a few countries. Because ties ... -
Asymmetric nickel-catalyzed three-component assembly of allylic amines from alkynes, imines and organoboron reagents
(Massachusetts Institute of Technology, 2004)[Image] ... Allylic amines are assembled in one step from alkynes, imines, and organoboron reagents (boronic acids or boranes) using a catalyst derived from Ni(cod)2 and (c-CsH9)3P or (o-anisyl)3P. This catalytic, ... -
Asymmetric nucleophilic catalysis with planar-chiral DMAP derivatives and chiral phosphines : synthetic and mechanistic studies
(Massachusetts Institute of Technology, 2014)Chapter 1 describes the development and detailed mechanistic investigation of the first non-enzymatic method for the dynamic kinetic resolution of secondary alcohols via enantioselective acylation, with acetyl isopropyl ... -
Asymmetric order-doubling and robust state estimation for uncertain nonminimum phase systems
(Massachusetts Institute of Technology, 1999) -
Asymmetric organic synthesis using organoboron compounds
(Massachusetts Institute of Technology, 1988) -
Asymmetric synthesis of amines by the catalytic enantioselective additions of hydrazoic acid to ketenes
(Massachusetts Institute of Technology, 2007)The development of a planar-chiral catalyst for the enantioselective additions of HN3 to hindered ketenes was investigated. It was demonstrated that a new planar-chiral catalyst (1.5) is an excellent catalyst for the ... -
The asymmetrical spine : a generator of design
(Massachusetts Institute of Technology, 1979) -
Asymmetries in Presupposition Projection: Processing and Acquisition
(Massachusetts Institute of Technology, 2022-09)In this dissertation, I aim to provide novel evidence to shed light on the projection problem of presuppositions. The focus is on identifying the underlying patterns of how presuppositions project out of two binary ... -
Asymmetry of will : the effect of religious radicalism on state military doctrine
(Massachusetts Institute of Technology, 2012)How is a state's military doctrine affected by the presence of radical religious ideology in its military? Using analysis of satellite imagery, recent military exercises, and a series of source interviews, I examine the ... -
Asymptotic analysis of extreme electrochemical transport
(Massachusetts Institute of Technology, 2005)In the study of electrochemical transport processes, experimental exploration currently outpaces theoretical understanding of new phenomena. Classical electrochemical transport theory is not equipped to explain the behavior ... -
Asymptotic analysis of hypersonic vehicle dynamics along entry trajectory
(Massachusetts Institute of Technology, 1991)
