#### Analysis of the swimming-to-crawling transition of Caenorhabditis elegans in viscous fluid

(Massachusetts Institute of Technology, 2008)

The locomotory behavior of the nematode Caenorhabditis elegans is often characterized by two distinct gaits - swimming when in fluids and crawling when on surfaces. Swimming is characterized by about a twice greater ...

#### The Gamma Intensity Monitor at the Crystal-Barrel-Experiment

(Massachusetts Institute of Technology, 2008)

This thesis details the motivation, design, construction, and testing of the Gamma Intensity Monitor (GIM) for the Crystal-Barrel-Experiment at the Universität Bonn. The CB-ELSA collaboration studies the baryon excitation ...

#### Spin-squeezing of ⁸⁷Rb via optical measurement

(Massachusetts Institute of Technology, 2008)

This project aims to reduce measurement uncertainty in atomic clocks by squeezing the collective spin of atoms. Spin-squeezing reduces noise below the standard quantum limit where precision scales as 1/ [square root of] ...

#### Tactic behaviors in bacterial dynamics

(Massachusetts Institute of Technology, 2005)

The locomotion of a wide class of motile bacteria can be mathematically described as a biased random walk in three-dimensional space. Fluid mechanics and probability theory are invoked to model the dynamics of bacteria ...

#### Solving the Dirac equation in a two-dimensional spacetime background with a kink

(Massachusetts Institute of Technology, 2005)

In the following paper, I study the Dirac equation in curved spacetime and solve this equation in two-dimensional spacetime backgrounds discovered by Jackiw et al[4], [5]. I will first discuss flat spacetime and introduce ...

#### Design and fabrication of sharp bend photonic crystal slab waveguides

(Massachusetts Institute of Technology, 2001)

A periodic arrangement of atoms in a crystal presents a periodic potential for electrons. The bragg diffraction of electrons from the atoms may lead to a band gap, which represents a range of frequencies the electrons ...

#### Higher levels of the transmon qubit

(Massachusetts Institute of Technology, 2014)

This thesis discusses recent experimental work in measuring the properties of higher levels in transmon qubit systems. The first part includes a thorough overview of transmon devices, explaining the principles of the device ...

#### Rigorous fit to the peak region of the thrust distribution

(Massachusetts Institute of Technology, 2014)

We continue the work of Abbate et al. in [1], in which a factorization formula for the thrust distribution in electron-positron collisions was developed in the framework of soft-collinear effective theory. We extend the ...

#### Implementation of scattering pinhole diagnostic for detection of fusion products on CR-39 at high particle fluence

(Massachusetts Institute of Technology, 2014)

Many Inertial Confinement Fusion (ICF) experiments use solid-state nuclear track detector CR-39 as a means to detect different types of nuclear products. Until recently, it was difficult to use CR-39 in experiments with ...

#### Designing and testing the neutron source deployment system and calibration plan for a dark matter detector

(Massachusetts Institute of Technology, 2011)

In this thesis, we designed and tested a calibration and deployment system for the MiniCLEAN dark matter detector. The deployment system uses a computer controlled winch to lower a canister containing a neutron source into ...
