Rotation of a slender rod injected into a cylindrical constraint
(Massachusetts Institute of Technology, 2016)
We investigate the buckling of a slender elastic rod injected into a cylindrical constraint while undergoing axial rotation. Particular focus is given to extension of the helical buckling length. This problem is of particular ...
Three dimensional printing with fine metal powders
(Massachusetts Institute of Technology, 1997)
In the area of direct metal part manufacture, the 3DPTM process has several inherent advantages over traditional machining and P/M technologies: hard tooling is not required to manufacture parts, geometries may be created ...
Development of experimental methods to measure osmosis-driven water flux and molecular transport across nanoporous graphene membranes
(Massachusetts Institute of Technology, 2015)
Graphene, an atomically thin planar lattice of sp2 bonded carbon atoms with high strength and impermeability, has drawn attention as a promising next generation high flux separation membrane. Molecular dynamics simulations ...
Development and application of a non invasive image matching method to study spine biomechanics
(Massachusetts Institute of Technology, 2008)
Research on spine biomechanics is critical to understand pathology such as degenerative changes and low back pain. However, current study on in-vivo spine biomechanics is limited by the complex anatomy and invasive ...
Analysis, design, and control of an omnidirectional mobile robot in rough terrain
(Massachusetts Institute of Technology, 2008)
An omnidirectional mobile robot is able, kinematically, to move in any direction regardless of current pose. To date, nearly all designs and analyses of omnidirectional mobile robots have considered the case of motion on ...
Suspended microchannel resonators for ultralow volume universal detection
(Massachusetts Institute of Technology, 2008)
Universal detectors that maintain high sensitivity as the detection volume is reduced to the sub-nanoliter scale can enhance the utility of miniaturized total analysis systems ([mu]-TAS). Here the unique scaling properties ...
Advancing clinical gait analysis through technology and policy
(Massachusetts Institute of Technology, 2009)
Quantitatively analyzing human gait biomechanics will improve our ability to diagnose and treat disability and to measure the effectiveness of assistive devices. Gait analysis is one technology used to analyze walking, but ...
Multiple part type decomposition method in manufacturing processing line
(Massachusetts Institute of Technology, 2001)
Combined dual emission laser induced fluorescence and particle image velocimetry to resolve temperature and velocity
(Massachusetts Institute of Technology, 2000)
Changes in the cation ordering of layered O3 Lix̳Ni₀.₅Mn₀.₅O₂ during electrochemical cycling to high voltages
(Massachusetts Institute of Technology, 2007)
Selected area electron diffraction patterns were collected from a pristine LiNi₀.₅Mn₀.₅O₂ sample and cycled Lix̳Ni₀.₅Mn₀.₅O₂ samples to 4.5 V and 5.3 V in the charged and discharged states. In the pristine sample, the ...
