A knee brace design to reduce the energy consumption of walking
(Massachusetts Institute of Technology, 2005)
Recent research into the mechanics of walking indicates that a quasi passive wearable device could be created which dramatically reduces the metabolic energy used in walking especially when the wearer is carrying additional ...
Three dimensional mapping of lingual myoarchitecture
(Massachusetts Institute of Technology, 2005)
The tongue is a structurally complex muscular organ, composed of a continuum of variably aligned intrinsic and extrinsic fibers. An understanding tongue structure and function, both under normal and pathological conditions, ...
High compliance all-terrain transport and heavy cargo hybrid bicycle
(Massachusetts Institute of Technology, 2005)
A design project was carried out which involved the design, manufacturing, and assembly of a hybrid bicycle. The bicycle was required to operate between two modes, one that permitted fast transport of the operator from one ...
Cycle-to-cycle control of multiple input-multiple output manufacturing processes
(Massachusetts Institute of Technology, 2005)
In-process closed-loop control of many manufacturing processes is impractical owing to the impossibility or the prohibitively high cost of placing sensors and actuators necessary for in-process control. Such processes are ...
Development of silicon insert molded plastic (SIMP)
(Massachusetts Institute of Technology, 2005)
As demand for smaller devices continues to increase, current manufacturing processes will find it more challenging to meet cost, quantity, and dimensional requirements. While microfabrication technology processes can create ...
Novel design of a rotary valve using axiomatic design
(Massachusetts Institute of Technology, 2005)
Rotary valves have existed for millennia; and while they have developed tremendously since the first Roman valves, many of the same problems have persisted. The basic problems are caused by the coupling of functional ...
The effect of modular acoustics on a performer's perception in multi-use (symphonic and operatic) concert halls
(Massachusetts Institute of Technology, 2005)
This thesis studies the varying degrees in a performer' s perception of the difference in the adjustable acoustics of a specific performance hall, namely, what is the difference between the opinions of instrumentalists and ...
Finite element simulation and parameter optimization of a flexible tactile pressure sensor array
(Massachusetts Institute of Technology, 2005)
A finite element model was developed to optimize design of a flexible tactile sensor. The sensor consists of layers of thin-film copper and PDMS, and the model can be used to determine the effects on sensor sensitivity and ...
Some modifications to the design of a parabolic solar concentrator for construction in Lesotho and their effects on power production
(Massachusetts Institute of Technology, 2005)
An experimental study was performed to test the effectiveness of design modifications terms of efficiency and power production in an existing parabolic solar concentrator. The proposed modifications included limiting the ...
Electromagnetically-driven ultra-fast tool servos for diamond turning
(Massachusetts Institute of Technology, 2005)
This thesis presents the design, implementation, and control of a new class of fast tool servos (FTS). The primary thesis contributions include the design and experimental demonstration of: novel ultra-fast electromagnetic ...
