Rheological characterization and modeling of Laponite gels with application to snug-like locomotion
(Massachusetts Institute of Technology, 2005)
Using various concentrations of Laponite, results were obtained on an AR1000 rheometer through various testing methods: stress sweep, creep tests, and large amplitude oscillatory shear tests, defined as LAOS. Concentrations ...
The development of an in vitro, one-pass, high-throughput model of flow dependent thrombosis
(Massachusetts Institute of Technology, 2005)
Thrombosis is an initiating response to a vascular injury, which aids in the repair and remodeling of the vessel wall. However, if this process remains unchecked, occlusion of the arterial lumen may quickly occur. The ...
Free air breathing planar PEM fuel cell design for portable electronics
(Massachusetts Institute of Technology, 2005)
PEM fuel cell technology is an energy source that can provide several times more energy per unit volume then current lithium ion batteries. However, PEM fuel cells remain to be optimized in volume and mass to create a ...
Low resonant frequency beam design for a piezoelectric energy harvesting device
(Massachusetts Institute of Technology, 2005)
The TREAD Act of 2000 proposed rules that will soon make tire pressure sensors standard on all automobiles. The trend seems to be for small chips that can be imbedded in tires and perform sensing, signal processing, and ...
Linearity, motor primitives and low-dimensionality in the spinal organization of motor control
(Massachusetts Institute of Technology, 2005)
The typical biological system is nonlinear, high-dimensional and highly redundant, all of which are burdens on controller design. Yet despite these complications, the central nervous system is able to control motor systems ...
Design of a silicon waver breaker
(Massachusetts Institute of Technology, 2005)
Usually multiple MEMS or IC devices are fabricated on a single silicon wafer. Manually separating the components from each other involves scribing and fracturing the silicon. This thesis presents a design for a tool to aid ...
HandSkates : an apparatus for physically intelligent exercise
(Massachusetts Institute of Technology, 2005)
Physical Intelligence refers to the ability of the human organism to smartly and precisely coordinate its internal components and interactions in its environment to solve physically complex tasks. While Physical Intelligence ...
Switchable stiffness scanning microscope probe
(Massachusetts Institute of Technology, 2005)
Atomic Force Microscopy (AFM) has rapidly gained widespread utilization as an imaging device and micro/nano-manipulator during recent years. This thesis investigates the new concept of a dual stiffness scanning probe with ...
Application of microfluidic emulsion technology to biochemistry, drug delivery and Lab-on-a-Chip programmability
(Massachusetts Institute of Technology, 2005)
This research applies microfluidic emulsion technology to three diverse problems; biochemistry, drug delivery and lab-on-a-chip programmability. These subjects represent distinct research programs, but the underlying physics ...
Characterization of Nb₃Sn superconducting strand under pure bending
(Massachusetts Institute of Technology, 2005)
Characterizing the strain-dependent behavior of technological Nb₃Sn superconducting strand has been an important subject of research for the past 25 years. Most of the effort has focused on understanding the uniaxial tension ...
