Associative learning in auditory thalamus and amygdala
(Massachusetts Institute of Technology, 2019)Although much pioneering work has furthered our understanding of the roles the medial geniculate nucleus of the thalamus (MGN) and basolateral amygdala (BLA) play in the formation of associative learning, many open questions ... -
Associative reinforcement learning for optimal control
(Massachusetts Institute of Technology, 1991) -
Assorted results in boolean function complexity, uniform sampling and clique partitions of graphs
(Massachusetts Institute of Technology, 2020)This thesis consists of three disparate parts. In the first, we generalize and extend recent ideas of Chiarelli, Hatami and Saks to obtain new bounds on the number of relevant variables for a boolean function in terms of ... -
Assortment and inventory optimization : from predictive choice models to near-optimal algorithms
(Massachusetts Institute of Technology, 2017)Finding optimal product offerings is a fundamental operational issue in modern retailing, exemplified by the development of recommendation systems and decision support tools. The challenge is that designing an accurate ... -
Assuring safety in high-speed magnetically levitated (maglev) systems : the need for a system safety approach
(Massachusetts Institute of Technology, 2008)Magnetic levitation is a railway technology that enables vehicles to be magnetically suspended above their tracks. Although this technology is still under development, magnetically levitated (maglev) systems have great ... -
Assuring safety through operational approval : challenges in assessing and approving the safety of systems-level changes in air transportation
(Massachusetts Institute of Technology, 2010)To improve capacity and efficiency of the air transportation system, a number of new systems-level changes have been proposed. Key aspects of the proposed changes are combined functionality across technology and procedures ... -
Asteroid deflection campaign design integrating epistemic uncertainty
(Massachusetts Institute of Technology, 2016)Planetary defense, or asteroid collision avoidance, has been gaining interest with recent meteor or fly-by events, including the Chelyabinsk meteor that entered the Earth's atmosphere and exploded over Russia in 2013. Past ... -
Asteroseismic Study of the Subgiant HD 82074
(Massachusetts Institute of Technology, 2014)This thesis analyzes HD 82074, a solar-mass and low-metallicity subgiant star, using ground-based asteroseismology with the CHIRON spectrometer at the Cerro Tololo Inter-American Observatory (CTIO) and interferometry with ... -
Astronaut adaptive arm motions on the MIR Space Station : kinematic analysis
(Massachusetts Institute of Technology, 1998) -
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, ...
