Profilometry with volume holographic imaging
(Massachusetts Institute of Technology, 2006)
High resolution, non-contact object profile measurement (profilometry) at long working distance is important in a number of application areas, such as precise parts manufacturing, optical element grounding and polishing, ...
A continuum theory with long-range forces for solids
(Massachusetts Institute of Technology, 2005)
A non-local integral-type continuum theory, introduced by Silling [61] as peridynamic theory, is analyzed. The theory differs from classical (local) continuum theories in that it involves long-range forces that act between ...
Active combustion control : modeling, design and implementation
(Massachusetts Institute of Technology, 2004)
Continuous combustion systems common in propulsion and power generation applications are susceptible to thermoacoustic instability, which occurs under lean burn conditions close to the flammability where most emissions and ...
Dynamics and statics of actin assemblies
(Massachusetts Institute of Technology, 2004)
The conversion of chemical energy into mechanical forces that powers cell movements is a ubiquitous theme across biology. The acrosome reaction of Limulus sperm is a simple example of such a dynamical transformation where ...
Compensating for model uncertainty in the control of cooperative field robots
(Massachusetts Institute of Technology, 2002)
Current control and planning algorithms are largely unsuitable for mobile robots in unstructured field environment due to uncertainties in the environment, task, robot models and sensors. A key problem is that it is often ...
Defining the role of elastic lubricants and micro textured surfaces in lubricated, sliding friction
(Massachusetts Institute of Technology, 2008)
Solutions for reducing friction in sliding, lubricated systems include modifying lubricant rheology using polymers and adding a micro-scale texture to the sliding surfaces, but the mechanism of how lubrication properties ...
MEMS relays for make-break power switching applications : {111} silicon etched planar electrical contacts
(Massachusetts Institute of Technology, 2008)
Relays and switches are of interest in applications such as test equipment, radar, communications, and power systems, amongst others. Unlike solid state switches, mechanical relays provide galvanic isolation across the ...
Combining adaptive and designed statistical experimentation : process improvement, data classification, experimental optimization and model building
(Massachusetts Institute of Technology, 2009)
Research interest in the use of adaptive experimentation has returned recently. This historic technique adapts and learns from each experimental run but requires quick runs and large effects. The basis of this renewed ...
The mechanical behavior of maraging steel under extreme electromechanical and thermal conditions
(Massachusetts Institute of Technology, 1989)
A virtual environment system for the study of human arm tremor
(Massachusetts Institute of Technology, 1989)
