U-Pb geochronology of the Acasta Gneiss Complex in Northwest Canada
(Massachusetts Institute of Technology, 2009)The Acasta Gneiss Complex in Northwest Canada contains the oldest dated rocks in the world. The gneisses range in age from 4.03-3.6 Ga, as determined by U-Pb dating of zircons (Bowring and Williams 1999). U-Pb dating of ... -
Ultimate load analysis using finite element methods
(Massachusetts Institute of Technology, 1978) -
Ultracold neutron storage simulation using the Kassiopeia software package
(Massachusetts Institute of Technology, 2019)The Kassiopeia software package was originally developed to simulate electromagnetic fields and charged particle trajectories for neutrino mass measurement experiments. Recent additions to Kassiopeia also allow it to ... -
Ultrafine aerosol deposition in planar channel flow
(Massachusetts Institute of Technology, 1994) -
Ultraportable surgical enclosure : human centered design for high usability in unpredictable environments
(Massachusetts Institute of Technology, 2020)Access to safe and sterile surgical infrastructure dramatically reduces the risk of infection for both patients and medical providers. However, this access is limited for many, especially those in austere environments and ... -
Ultrasonic wave propagation in thick, layered composites containing degraded interfaces
(Massachusetts Institute of Technology, 2005)The ultrasonic wave propagation of thick, layered composites containing degraded bonds is investigated. A theoretical one-dimensional model of three attenuative viscoelastic layers containing two imperfect interfaces is ... -
Ultrasound : an alternative solution for removing tattoos
(Massachusetts Institute of Technology, 2005)The recent influx of tattoos has been accompanied by a rise in demand for tattoo removals. Due to the recent success of ultrasound as a noninvasive alternative for multiple medical therapies, the feasibility of ultrasound-mediated ... -
Ultraviolet laser calibration of drift chambers
(Massachusetts Institute of Technology, 2006)We demonstrate the use of a focused ultraviolet laser as a track calibration source in drift chambers, and specifically in a small time projection chamber (TPC). Drift chambers such as TPCs reconstruct the trajectories of ... -
Umplementation of Mathematica® interface for DOME (Distributed Object-based Modeling Environment)
(Massachusetts Institute of Technology, 2001) -
Uncertainty and sensitivity analysis of a fire-induced accident scenario involving binary variables and mechanistic codes
(Massachusetts Institute of Technology, 2010)In response to the transition by the United States Nuclear Regulatory Commission (NRC) to a risk-informed, performance-based fire protection rulemaking standard, Fire Probabilistic Risk Assessment (PRA) methods have been ... -
Uncovering the Structure of the Galactic Bulge Using Kinematic Data from the JASMINE Near-Infrared Astrometric Satellite
(Massachusetts Institute of Technology, 2021-06)The Galactic Center (GC) is the region with the most extreme stellar densities, a strong gravitational field, and the most prolific star formation region in the Milky Way. Furthermore, the Milky Way is the only galaxy that ... -
An undergraduate dormitory for M.I.T.
(Massachusetts Institute of Technology, 1958) -
Underneath
(Massachusetts Institute of Technology, 2012)Underneath is a full-length novel that follows Maggie Lawrence, a twelve-year-old girl growing up in the late 1970s, through the first eight months of her parents' divorce. To escape their fighting, Maggie crawls under her ... -
The understanding and use of radio and television in the urban planning profession
(Massachusetts Institute of Technology, 1981) -
Understanding changes in precipitation with climate change over wet and dry land
(Massachusetts Institute of Technology, 2021-06)Observed precipitation increased moderately in both wet and dry regions over the past 60 years, contradicting the wet-gets-wetter, dry-gets-drier (WWDD) mechanism. This study uses the perturbation atmospheric energy budget ... -
Understanding collagen-l folding and misfolding
(Massachusetts Institute of Technology, 2015)Chapter One: Introduction to Type I Collagen and Osteogenesis Imperfecta Collagen-I is the primary proteinaceous component of skin, bone, and tendon. Disruptions in collagen-I homeostasis, typically due to non-synonymous ... -
Understanding frequency response of a flexural complaint stage for use in oscillatory orthogonal cutting
(Massachusetts Institute of Technology, 2015)Ultramicrotomy is the process of cutting specimens into submicron-thickness slices for subsequent imaging using a scanning electron microscope (SEM). Ultramicrotomes, devices that employ this process, have incorporated ... -
Understanding the careers of the alumni of the MIT Mechanical Engineering department
(Massachusetts Institute of Technology, 2004)This research seeks to understand the careers of MIT mechanical engineering alumni. Data was collected to determine the knowledge and skills that graduates from the classes of 1992 through 1996 make use of in their ... -
Understanding the catalytic machinery of chondroitinase ABC I in processing dermatan sulfate
(Massachusetts Institute of Technology, 2007)In recent studies related to injury to the central nervous system, researchers have found that galactosaminoglycans can serve as inhibitors to neuron regeneration. The chondroitinase enzyme family is comprised of several ... -
