Enabling effective product launch decisions
(Massachusetts Institute of Technology, 2008)
The present work looks into the question of optimizing the performance of product launch decisions-in particular, the decisions of product development duration and manufacturing ramp-up. It presents an innovative model for ...
Efficient localization in a dispersive waveguide : applications in terrestrial continental shelves and on Europa
(Massachusetts Institute of Technology, 2006)
Methods are developed for passive source localization and environmental parameter estimation in seismo-acoustic waveguides by exploiting the dispersive behavior of guided wave propagation. The methods developed are applied ...
Rough-terrain mobile robot planning and control with application to planetary exploration
(Massachusetts Institute of Technology, 2001)
Future planetary exploration missions will require mobile robots to perform difficult tasks in highly challenging terrain, with limited human supervision. Current motion planning and control algorithms are not well suited ...
Detecting cervical dysplasia with quantitative spectroscopic imaging
(Massachusetts Institute of Technology, 2009)
This thesis extends quantitative spectroscopy, a form of model-based reflectance and fluorescence spectroscopy, from a small area, contact-probe implementation to wide-area quantitative spectroscopic imaging (QSI) for ...
Manufacturing conductive patterns on polymeric substrates : development of a microcontact printing process
(Massachusetts Institute of Technology, 2013)
The focus of this research was to develop a process suitable for creating very high resolution conductive patterns on polymer substrates, in a way that can be scaled to high volume manufacturing. The original motivation ...
Material properties of actin filament bundles
(Massachusetts Institute of Technology, 2009)
Actin is an ubiquitous structural protein fundamental to such biological processes as cell motility and muscle contraction. Our model system is the acrosomal process of the Limulus sperm which extends a 60 ýtm long actin ...
Effect of loading history in necking and fracture
(Massachusetts Institute of Technology, 2008)
The effect of Lode angle parameter, or the third deviatoric stress invariant, on plasticity and fracture is studied using flat-grooved transverse plane strain specimens. A generalized asymmetric plasticity model for isotropic ...
Carbon nanotube based electromechanical probes
(Massachusetts Institute of Technology, 2007)
Electromechanical probing applications continuously require smaller pitches, faster manufacturing and lower electrical resistance. Conventional techniques, such as MEMS based cantilever probes have their shortcomings in ...
