Spinal cord implants for nerve regeneration
(Massachusetts Institute of Technology, 2004)
It has only been in the last couple decades that the potential for regeneration in the spinal cord became accepted. However, there is still no proven method for enabling this regeneration. An implant model was developed ...
MEMS-based resonant sensor arrays : selective detection of volatile and toxic chemicals
(Massachusetts Institute of Technology, 2004)
With growing concerns about homeland security, public health, and environmental cleanliness, there is a strong need today for robust chemical sensing systems that are portable in addition to being highly sensitive. While ...
The document synchronizer : a partial solution for real-time replication
(Massachusetts Institute of Technology, 1996)
Assessment of collagen based polymer scaffolds for tissue engineering
(Massachusetts Institute of Technology, 2002)
The use of collagen-glycosaminoglycan copolymers in tissue engineering scaffolds has seen promise to date in skin regeneration templates, hollow nerve guides for peripheral nerve regeneration, and conjunctiva regeneration. ...
The impact of improved materials in poly(vinyl chloride)-based endotracheal tubes
(Massachusetts Institute of Technology, 2004)
Endotracheal tubes (ETs) are used to aid artificial ventilation in millions of medical patients every year and are known to invoke the proliferative phase in the cell linings. The technical objective of this work was to ...
Commercialization potential of compositionally graded Ge - Si₁₋x̳Gex̳ - Si substrates for solar applications
(Massachusetts Institute of Technology, 2006)
This project considers the potential of Ge - Si₁₋x̳Gex̳ - Si substrates for solar applications. The use of compositionally graded substrates to achieve heterointegration across different materials platforms such as Si, Ge ...
Evaluation of potential applications for templated arrays of heterostructural semiconductor nanowires as light emitting devices
(Massachusetts Institute of Technology, 2006)
While light emitting devices, such as laser diodes (LDs) and light emitting diodes (LEDs), were first introduced decades ago, they have been the subject of continuing research and improvements due to their relatively poor ...
Natural attenuation of chlorinated solvents at Ashumet Valley, Cape Cod, Massachusetts
(Massachusetts Institute of Technology, 1997)
Improved Runtimes and Lower Bounds for Dual-Edge Failure Replacement Path Algorithms
(Massachusetts Institute of Technology, 2021-06)
Given a graph G and a fixed pair of nodes s and t, the Replacement Paths problem is to compute the new shortest distance from s to t when there are edge failures in G (i.e. those edges can no longer be used for any path). ...
ProgGen: Automatic Dataset Generation for the Halide Domain Specific Language
(Massachusetts Institute of Technology, 2021-06)
Compilers use cost models to choose between different optimization opportunities, and increasingly these cost models are developed using data-driven techniques. Compilers for general-purpose languages rely on large real-world ...
