Light manipulation with photonic fibers and optical light guides : dynamic structural color and light distribution in microalgae cultures
(Massachusetts Institute of Technology, 2020)
Optical and photonic fibers represent versatile systems for light manipulation. They are used to guide, reflect, emit, and absorb light, and can be designed to alter the light's spectral composition in any of these ...
Parametric design and performance validation of low-cost, low-pressure drip emitters and irrigation systems
(Massachusetts Institute of Technology, 2020)
This thesis proposes and validates methods to reduce the cost and energy use of drip irrigation systems, with the aim of increasing their adoption among smallholder farmers. By 2050, the growing world population will require ...
Learning and investigating phenomenological models for active matter
(Massachusetts Institute of Technology, 2021-09)
Active matter, such as a suspension of swimming cells or colloidal particles, or even a flock of birds, consists of self-propelled units that convert stored or ambient free energy into motion. Recent advances in high-resolution ...
Development and Validation of a Passive Prosthetic Foot Design Framework based on Lower Leg Dynamics
(Massachusetts Institute of Technology, 2021-09)
People with lower limb amputations face considerable challenges to everyday mobility that affect their quality of life. This is especially the case in low and middle income countries (LMIC) where the lack of affordable ...
High throughput extrusion additive manufacturing – rate limits and system design
(Massachusetts Institute of Technology, 2021-09)
Fused filament fabrication (FFF) is an additive manufacturing (AM) process in which a polymer feedstock is melted and extruded through a nozzle while guided by a motion system, resulting in a three-dimensional part. FFF ...
A Virtual Ocean framework for environmentally adaptive, embedded acoustic navigation on autonomous underwater vehicles
(Massachusetts Institute of Technology, 2021-09)
Autonomous underwater vehicles (AUVs) are an increasingly capable robotic platform, with embedded acoustic sensing to facilitate navigation, communication, and collaboration. The global positioning system (GPS), ubiquitous ...
A model for the dig-in instability in serial sectioning and iterative orthogonal cutting
(Massachusetts Institute of Technology, 2021)
Microtome serial sectioning is a key part of building brain maps of neurological tissue, which are made by serially cutting resin-embedded brain tissue into thin sections, followed by imaging on an electron microscope; ...
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 ...
Neuromorphic computing systems : crystalline resistive random access memory
(Massachusetts Institute of Technology, 2020)
Neuromorphic computing is a promising approach for efficient electronics by shaping computer hardware like the human brain. At the core of neuromorphic architectures are artificial synapses, which store conductance states ...
Prediction, analysis, and learning of advective transport in dynamic fluid flows
(Massachusetts Institute of Technology, 2021)
Transport of any material quantity due to background fields, i.e. advective transport, in fluid dynamical systems has been a widely studied problem. It is of crucial importance in classical fluid mechanics, geophysical ...
