A worker-centered approach to convex optimization in engineering design
(Massachusetts Institute of Technology, 2020)
Design tools shape what engineers and their organizations consider desirable. In particular, "design models" that implement interactions amongst parameters are central to the work of early-stage concept development. Such ...
An injectable, biomaterial-based therapy to promote endogenous neural progenitor cells in a hemorrhagic stroke lesion
(Massachusetts Institute of Technology, 2020)
Stroke is the second leading cause of death and disability worldwide with prevalence and resulting costs projected to increase. There are few available treatments, and their applicability is limited to the type of stroke ...
Analysis and algorithms for parametrization, optimization and customization of sled hockey equipment and other dynamical systems
(Massachusetts Institute of Technology, 2020)
A dynamical system, an ensemble of particles, states of which evolve over time, can be described using a system of ordinary/partial differential equations (ODEs/PDEs). This dissertation presents fundamental investigations ...
Nanoengineered hierarchical advanced composites with nanofiber interlaminar reinforcement for enhanced laminate-level mechanical performance
(Massachusetts Institute of Technology, 2020)
At present, there is a need for novel, scalable, and high-performance structural materials that offer unprecedented combinations of stiffness, strength, and toughness at a low density, which can serve in a variety of ...
Mechanism and Applications of large and persistent photoconductivity in cadmium sulfide
(Massachusetts Institute of Technology, 2020)
Photoconductivity is the phenomenon where electrical conductivity changes as a result of photoexcitation of new charge carriers. In some semiconductors, photoconductivity is accompanied with enormous conductivity change ...
Dexterous manipulation with simple grippers
(Massachusetts Institute of Technology, 2020)
This thesis focuses on enabling robots, specially those with simple grippers, to dexterously manipulate an object in a grasp. The dexterity of a robot is not limited to the intrinsic capability of a gripper. The robot can ...
Design and development of desktop fiber and fabric manufacturing system for advanced materials
(Massachusetts Institute of Technology, 2020)
This thesis presents two novel desktop fiber manufacturing systems and a desktop fabric manufacturing system. The desktop fiber manufacturing system achieved two goals. The first goal was the use of the system to teach ...
Accelerating cleantech hardware product development
(Massachusetts Institute of Technology, 2020)
Startups in the Cleantech sector have historically had poor return on investment and high failure rates when compared with the medical or software sectors. One reason given for the disappointing outcomes of many Cleantech ...
Machine learning in ocean applications : wave prediction for advanced controls of renewable energy and modeling nonlinear viscous hydrodynamics
(Massachusetts Institute of Technology, 2020)
Many conventional problems in ocean engineering remain challenging due to the stochastic nature of ocean waves, viscous effects of the flow, nonlinear resonance, etc., and the combination of these factors. Data-driven ...
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 ...
