1D-to-3D transition of photon heat conduction in polyethylene using molecular dynamics simulations
(Massachusetts Institute of Technology, 2009)Experiments have demonstrated that the mechanical stretching of bulk polyethylene can increase its thermal conductivity by more than two orders of magnitude, from 0.35 W/mK to over 40W/mK, which is comparable to steel. ... -
2.672 experiment design : heat sink fin configurations
(Massachusetts Institute of Technology, 2007)2.672 is an undergraduate mechanical engineering laboratory course which requires students to solve real-world problems using both theoretical calculations and laboratory experiments. Many of the experiments currently in ... -
2007 Formula SAE pedal box
(Massachusetts Institute of Technology, 2007)The purpose of this thesis is the design and implementation of the pedal box for the 2007 MIT Formula SAE car. Formula SAE is a collegiate competition in which groups of degree seeking students design and manufacture small ... -

(Massachusetts Institute of Technology, 2014)3D visualization of fluid flow is of critical significance to a number of applications ranging from micro-scale medical devices to design of ships and airplanes. Of the various techniques currently used to visualize flow ... -
3D reconstruction from 2D images and applications to cell cytoskeleton
(Massachusetts Institute of Technology, 2001)Approaches to achieve three dimensional (3D) reconstruction from 2D images can be grouped into two categories: computer-vision-based reconstruction and tomographic reconstruction. By exploring both the differences and ... -
A-Posteriori bounds on linear functionals of coercive 2nd order PDEs using discontinuous Galerkin methods
(Massachusetts Institute of Technology, 2006)In this thesis, we extend current capabilities in producing error bounds on the exact linear functionals of linear partial differential equations in a number of ways. Unlike previous approaches, we base our method on the ... -
Ab initio simulation and optimization of phonon drag effect for lower-temperature thermoelectric energy
(Massachusetts Institute of Technology, 2015)In recent years, extensive efforts have been devoted to searching for materials with high thermoelectric (TE) efficiency above room temperature for converting heat into electricity. These efforts have led to significant ... -
Ab Initio study of dynamically tunable catalysis for carbon dioxide reduction
(Massachusetts Institute of Technology, 2017)Catalytic conversion of CO₂into useful chemicals is an attractive alternative to expensive physical carbon sequestration methods. However, this approach is challenging because current chemical conversion methods employ ... -
Ab initio study of electron transport in lead telluride
(Massachusetts Institute of Technology, 2018)Last few years have witnessed significant enhancement of thermoelectric figure of merit of lead telluride (PbTe) via nanostructures. Despite the experimental progress, current understanding of the electron transport in ... -
Abdominal vacuum lift as an aid to diagnosing abdominal adhesions
(Massachusetts Institute of Technology, 2006)The internal organs are designed to move freely and slide over one another during normal body movement. The abdominal organs, however, have a tendency to adhere to the abdominal cavity (peritoneum) and other abdominal ... -
