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 ...
Estimation of oil consumption due to in-cylinder vaproization in internal combustion engines
(Massachusetts Institute of Technology, 1999)
Two models were developed to estimate the rate of oil consumption due to the vaporization of oil from (1) the cylinder liner and from (2) the piston ringpack in an internal combustion engine. The purpose of the models is ...
Analysis of the accessory business : focus on electromechanical grips
(Massachusetts Institute of Technology, 1999)
Today, many manufacturing companies are facing numerous challenges that had not been present in the past. The paradigm of how companies must perform has dramatically changed over the years. Back in the 1980's customer ...
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 ...
Vehicle model-based filtering for spacecraft attitude determination
(Massachusetts Institute of Technology, 1998)
This thesis investigates the use of vehicle model-based filtering for spacecraft attitude determination. Whereas traditional navigation filters typically rely only on the kinematic relations between body rate and attitude ...
Management of a high mix production system with interdependent demands : simulation of proposed policies
(Massachusetts Institute of Technology, 2009)
The finished goods inventory management in the accessories area of a material testing company is complex. There is interdependence between the demands of products and they can be sold both as part of systems and as individual ...
