Development of a beamline system for characterization of Xray and neutron optics
(Massachusetts Institute of Technology, 2016)In this thesis, I present a beamline system designed and built at the HarvardSmithsonian Center for Astrophysics (CfA) to measure the reflectivity and resolution of small diameter multilayer coated Wolter optics. These ... 
Development of a polarized Helium3 ion source for RHIC using the electron beam ion source
(Massachusetts Institute of Technology, 2013)This thesis presents my work on the design and development of a source of polarized Helium3 ions for the Relativistic Heavy Ion Collider at Brookhaven National Lab, Upton, NY. The 3He atoms will be polarized using the ... 
Differential cross section measurement for the d(n,np) reaction
(Massachusetts Institute of Technology, 2010)The differential cross section for the quasielastic d(n,np) neutroninduced deuteron breakup reaction was measured as a function of incident and scattered particle energies and angles, using a liquid deuterium target at ... 
Diffusional instabilities on curved manifolds
(Massachusetts Institute of Technology, 2018)Diffusionallydriven instabilities provide a versatile mechanism for pattern formation, and have found applications in modeling a variety of biological and chemical systems. Although pattern formation has been observed in ... 
A diquark interpretation of the structure and energies of hadrons
(Massachusetts Institute of Technology, 2005)I present a simple phenomenological model which successfully organizes and classifies essentially all hadrons. The model is originally inspired from three simple theoretical indications including: treating baryons as a two ... 
Direction of spin of Koronis family member (1289) Kutaïssi
(Massachusetts Institute of Technology, 2003)Observations of lightcurve of Koronis family member asteroid (1289) Kutaïssi were taken in January, 2003, at MIT's Wallace Astrophysical Observatory. The goal of these observations included obtaining a precise rotation ...

DLTS characterization of aluminum gettering of iron contaminants in borondoped silicon
(Massachusetts Institute of Technology, 1996) 
Doppler shifts in the KATRIN experiment
(Massachusetts Institute of Technology, 2008)In the past few decades, neutrinos, which are predicted to be massless particles by the Standard Model of Particle Physics, have been shown to have nonzero mass. The absolute scale of this neutrino mass has significant ... 
Double streaming at 35 AU during the coronal mass ejections of March 1991
(Massachusetts Institute of Technology, 2009)We analyze data associated with the coronal mass ejections of March 1991, with emphasis on a remarkable doublestreaming proton event observed at 35 AU. The plasma data used in our analysis were collected by three spacecraft: ... 
Dynamic light scattering and diffusing wave spectroscopy studies of the microscopic dynamics of polystyrene latex spheres suspened in glycerol
(Massachusetts Institute of Technology, 1999)The dynamics of polystyrene latex spheres [650 A radius] suspended in glycerol have been studied using the techniques of dynamic light scattering in the single scattering limit and diffusing wave spectroscopy in the multiple ... 
Dynamic line integral convolution for quantum hydrodynamics
(Massachusetts Institute of Technology, 2019)This thesis demonstrates the application of the dynamic line integral convolution (DLIC) algorithm to the GrossPitaevskii equation and quantum hydrodynamics. Line integral convolution is a powerful method of visualizing ... 
Dynamic line integral convolution for visualizing electromagnetic phenomena
(Massachusetts Institute of Technology, 2001)Vector field visualization is a useful tool in science and engineering, giving us a powerful way of understanding the structure and evolution of the field. A fairly recent technique called Line Integral Convolution (LIC) ... 
The dynamics of enzymatic switch cascades
(Massachusetts Institute of Technology, 2004)We examine the dynamics of the mitogenactivated protein kinase (MAPK) multistep enzymatic switching cascade, a highly conserved architecture utilised in cellular signal transduction. In treating the equations of motion, ... 
The effect of crystalline orientation and band nonparabolicity on the electronic properties of bismuth nanowires
(Massachusetts Institute of Technology, 2008)Due to the unique electronic properties of bismuth, bismuth nanowires provide an attractive lowdimensional system for studying quantum confinement effects, and have generated much interest in both optical and thermoelectric ... 
The effect of higher order moments in the postNewtonian gravitational wave expansion on parameter estimation
(Massachusetts Institute of Technology, 2008)The purpose of this thesis is to investigate both the qualitative and quantitative effects of including higher order amplitude terms in the postNewtonian expansion for gravitational waves on parameter estimation of ... 
Effect of magnetic seed fields on Lyman Alpha emission from distant quasars
(Massachusetts Institute of Technology, 2016)There are indications that weak magnetic fields originating in the early Universe and magnified via magnetohydrodynamic (MHD) processes could cause perturbations in the thermodynamic state of the gas in the intergalactic ... 
Effective action approach to quantum phase transitions in bosonic lattices
