Engineering micro-perfusable scaffolds for MesoPhysiological Systems using projection Micro-StereoLithography
(Massachusetts Institute of Technology, 2020)
MicroPhysiological Systems (MPS) are in vitro models that capture the complexity of human organs at miniature scale by recreating the native microenvironment of resident cells. These systems offer promising alternatives ...
Are two heads better than one in CAD? a comparison of various CAD working styles
(Massachusetts Institute of Technology, 2020)
Collaboration in Computer-Aided Design (CAD) has existed since the inception of CAD tools. The established norm in multi-user CAD work has been to use top-down modeling techniques wherein a complex model is divided into ...
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), ...
Systems and control theoretic approaches to engineer robust biological systems
(Massachusetts Institute of Technology, 2020)
Synthetic biology is an emerging field of research aimed to engineer biological systems by inserting programmed DNA molecules into living cells. These DNAs encode the production and subsequent interactions of biomolecules ...
Thermal energy grid storage : liquid containment and pumping
(Massachusetts Institute of Technology, 2020)
As the cost of renewable energy falls below fossil fuels, the key barrier to widespread sustainable electricity has become availability on demand. Energy storage can enable dispatchable renewables, but only with drastic ...
Transfer learning and robustness for natural language processing
(Massachusetts Institute of Technology, 2020)
Teaching machines to understand human language is one of the most elusive and long-standing challenges in Natural Language Processing (NLP). Driven by the fast development of deep learning, state-of-the-art NLP models have ...
Algorithms for robust autonomous navigation in human environments
(Massachusetts Institute of Technology, 2020)
Today's robots are designed for humans, but are rarely deployed among humans. This thesis addresses problems of perception, planning, and safety that arise when deploying a mobile robot in human environments. A first key ...
Fast modeling of multi-phase mixture transport in piston/ring/liner system via GAN-augmented progressive modeling
(Massachusetts Institute of Technology, 2020)
As a continued effort to advance the understanding of the power cylinder system and design capacities, we develop a modeling framework for multi-phase macro mixture transport that integrates all length scales, time scales ...
Instabilities of finite-width internal wave beams
(Massachusetts Institute of Technology, 2020)
Internal gravity waves are fundamental to the dynamics of density stratified fluids and the instability mechanisms by which these waves dissipate their energy are a potentially significant factor that underlies the ...
Morphological approaches to understanding Antarctic Sea ice thickness
(Massachusetts Institute of Technology, 2020)
Sea ice thickness has long been an under-measured quantity, even in the satellite era. The snow surface elevation, which is far easier to measure, cannot be directly converted into sea ice thickness estimates without ...
