An evaluation of short innovation contest implementation in the federal context
(Massachusetts Institute of Technology, 2013)
Technologies over the past three decades have democratized the tools of knowledge creation, thus creating increasing communities of innovators outside traditional organizations' boundaries. Cost effective ways of leveraging ...
The effect of dust blowback on spatial orientation estimation during lunar landing
(Massachusetts Institute of Technology, 2013)
Landing is a dangerous and complex phase of any flight. Landing on an airless, dusty world presents unique challenges to perception, including dust blowback. During crewed lunar landings, astronauts will either be directly ...
Autonomous control and membrane maintenance optimization of photovoltaic reverse osmosis systems
(Massachusetts Institute of Technology, 2013)
The supply of clean water in remote and off-grid areas has been a major global challenge for humanity. Over 780 million people lack access to clean water [1]. However, a significant fraction of these people have access to ...
RM methods for airline fare family structures
(Massachusetts Institute of Technology, 2013)
The rapid growth of low cost carriers forced many legacy airlines to simplify their fare structures and develop new pricing strategies to remain competitive. The strategy of branded fares, or "fare families", is an ...
Three-dimensional constitutive relations of aligned carbon nanotube polymer nanocomposites
(Massachusetts Institute of Technology, 2013)
We have created a set of decision support tools to streamline the surgical case scheduling process by allowing surgical wait list cases (elective cases that cannot be assigned a slot on the operating room schedule at the ...
Fast, approximate state estimation of concurrent probabilistic hybrid automata
(Massachusetts Institute of Technology, 2013)
It is an undeniable fact that autonomous systems are simultaneously becoming more common place, more complex, and deployed in more inhospitable environments. Examples include smart homes, smart cars, Mars rovers, unmanned ...
Design, analysis, and testing of a precision guidance, navigation, and control system for a dual-spinning Cubesat
(Massachusetts Institute of Technology, 2013)
The Microsized Microwave Atmospheric Satellite (MicroMAS) combines two traditional control approaches: a dual spinner and a three-axis gyrostat. Unlike typical dual spinners, the purpose of MicroMAS 's 2U bus and spinner ...
The influence of runway occupancy time and wake vortex separation requirements on runway throughput
(Massachusetts Institute of Technology, 2013)
Air traffic growth in the U.S. has led to runway capacity constraints in the air transportation network. There has been limited new construction of runways due to land availability. One approach to increase capacity of ...
From CubeSats to constellations : systems design and performance analysis
(Massachusetts Institute of Technology, 2013)
The primary purpose of an Earth observing spacecraft constellation is to obtain global measurements with improved spatial and temporal resolution. The small size, low cost, standardized form factor, and increasing availability ...
Hierarchical carbon fiber composites with radially aligned carbon nanotubes : preservation of in-plane tensile properties
(Massachusetts Institute of Technology, 2013)
Hierarchical carbon-nanotube (CNT)-based composites have significant potential to expand the performance and functionality of aerospace composite structures. Notably, circumferentially aligned CNT arrays have previously ...
