3-dimensional modeling and simulation of surface and sidewall roughening during plasma etching
(Massachusetts Institute of Technology, 2008)Line edge roughness (LER) on the sidewalls of gate electrodes in metal oxide semiconductor transistors is one of the most important issues in the manufacturing of modem integrated circuits (IC). The significance of LER ... -
3-dimensional surface imaging using Active Wavefront Sampling
(Massachusetts Institute of Technology, 2006)A novel 3D surface imaging technique using Active Wavefront Sampling (AWS) is presented. In this technique, the optical wavefront traversing a lens is sampled at two or more off-axis locations and the resulting motion of ... -

3D assembly and actuation of nanopatterned membranes using nanomagnets
(Massachusetts Institute of Technology, 2011)A new method for aligning and actuating membranes for 3D nano-assembly based on the interactions of nanomagnets has been developed. Arrays of nanopatterned magnetic material are integrated onto thin-film membranes. It is ... -
3D chromosome structure and chromatin proteomics
(Massachusetts Institute of Technology, 2016)The selective interpretation of the genome through transcription enables the production of every cell type's distinct gene expression program from a common genome. Transcription takes place within, and is controlled by, ... -
The 3D instability of a strained vortex and its relation to turbulence
(Massachusetts Institute of Technology, 1989) -
3D MEMS via (post-) buckling of micromachined structures and integration of bulk nanoporous elements in microfluidic devices
(Massachusetts Institute of Technology, 2011)The last two decades have seen a proliferation of fields and applications where microtechnologies have gradually replaced, and often outperformed, their macroscopic counterparts. From engineering to basic sciences, ... -
3D model-based pose estimation of rigid objects from a single image for robotics
(Massachusetts Institute of Technology, 2015)We address the problem of finding the best 3D pose for a known object, supported on a horizontal plane, in a cluttered scene in which the object is not significantly occluded. We assume that we are operating with RGB-D ... -
A 3D neuromuscular model of the human ankle-foot complex based on multi-joint biplanar fluoroscopy gait analysis
(Massachusetts Institute of Technology, 2018)During the gait cycle, the human ankle complex serves as a primary power generator while simultaneously stabilizing the entire limb. These actions are controlled by an intricate interplay of several lower leg muscles that ... -
3D organ property mapping using freehand ultrasound scans
(Massachusetts Institute of Technology, 2020)3D organ property mapping has gained a considerable amount of interest in the recent years because of its diagnostic and clinical significance. Existing methods for 3D property mapping include computed tomography (CT), ... -
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 ... -
3D Spatial Perception with Real-Time Dense Metric-Semantic SLAM
(Massachusetts Institute of Technology, 2023-02)3D Spatial Perception is the ability of an agent to perceive and understand the three-dimensional structure of its environment, including its position and orientation within that environment. This ability is essential for ... -
