Passive Health Monitoring with RadioWaves —In Body and In Home
(Massachusetts Institute of Technology, 2022-09)Current health care is primarily in-clinic, episodic, and semi-empirical. With the development of intelligent devices such as smartphones, smartwatches, and more cutting-edge devices such as in-body devices and contactless ... -
A passive infrared ice detection technique for helicopter applications
(Massachusetts Institute of Technology, 1991) -
Passive localization of underwater acoustic beacons
(Massachusetts Institute of Technology, 1993) -
Passive microfluidic interconnects
(Massachusetts Institute of Technology, 2005)Equipment and procedures were developed to test two passive microfluidic interconnect rings held together by the friction forces on the contact surfaces. The second design forms fluid seals by means of thin flared rings ... -
Passive microwave and hyperspectral infrared retrievals of atmospheric water vapor profiles
(Massachusetts Institute of Technology, 2001)Two clear-air relative humidity profile estimators were designed and implemented using neural networks. The microwave estimator is the first to utilize 54-, 118-, and 183-GHz channels for simultaneously retrieving a relative ... -
Passive millimeter-wave retrieval of global precipitation utilizing satellites and a numerical weather prediction model
(Massachusetts Institute of Technology, 2007)This thesis develops and validates the MM5/TBSCAT/F([lambda]) model, composed of a mesoscale numerical weather prediction (NWP) model (MM5), a two-stream radiative transfer model (TBSCAT), and electromagnetic models for ... -
Passive mobile robot localization within a fixed beacon field
(Massachusetts Institute of Technology, 2006)This thesis describes a geometric algorithm for the localization of mobile nodes in networks of sensors and robots using bounded regions, in particular we explore the range-only and angle-only measurement cases. The algorithm ... -
Passive motion control of super tall buildings : tuned mass and viscous dampers in Taipei 101.
(Massachusetts Institute of Technology, 2009)As tall buildings keep becoming taller, they become more susceptible to dynamic excitations such as wind and seismic excitations. One way to reduce structural vibration under dynamic excitations is by placing damping devices ... -
Passive object recognition using intrinsic shape signatures
(Massachusetts Institute of Technology, 2011)The Agile Robotics Group (AR) at MIT's Computer Science and Artificial Intelligence Laboratories (CSAIL) has an autonomous, forklift capable of doing task planning, navigation, obstacle detection and avoidance, focused ... -
Passive phloem loading and long-distance transport in a synthetic tree-on-a-chip
(Massachusetts Institute of Technology, 2015)According to the Munch mechanism, vascular plants rely on osmotic pressure gradients to export sugars from regions of synthesis (mature leaves) to sugar sinks (roots, fruits). A crucial step in this process is the loading ... -
Passive regeneration : long-term effects on ash characteristics and diesel particulate filter performance
(Massachusetts Institute of Technology, 2013)Diesel particulate filters (DPF) have seen widespread growth as an effective means for meeting increasingly rigorous particle emissions regulations. There is growing interest to exploit passive regeneration of DPFs to ... -
Passive sensing of user behavior and Well-being at home
(Massachusetts Institute of Technology, 2020)Learning people's behavior in their homes is central to health sensing, behavioral research, and building smarter environments. In this thesis, we explore learning such information in a passive and contactless manner - ... -
Passive solar energy conservation in industrialized housing.
(Massachusetts Institute of Technology, 1978) -
Passive solar for urban tenement housing : case study and retrofit design for West-Berlin
(Massachusetts Institute of Technology, 1981)Studies about residential passive solar heating have been conducted in many countries, mostly dealing with new or existing single family houses and nearly unlimited access to the sun. Only a few studies are related to ... -
Passive solar in the city : an energy conscious design for subsidized multi-family housing development
(Massachusetts Institute of Technology, 1981)Until now, passive solar energy has been overlooked as a viable alternative for home heating in urban subsidized housing. Rather ironically, in housing whose residents could most benefit from the use of solar energy, such ... -
Passive stabilization of flywheel magnetic bearings
(Massachusetts Institute of Technology, 1980) -
Passive wake detection using seal whisker-inspired sensing
(Massachusetts Institute of Technology, 2015)This thesis is motivated by a series of biological experiments that display the harbor seal's extraordinary ability to track the wake of an object several seconds after it has swum by. They do so despite having auditory ... -
Passive wearable electrostatic tags
(Massachusetts Institute of Technology, 1997) -
A passively-safe fusion reactor blanket with helium coolant and steel structure
(Massachusetts Institute of Technology, 1994) -
Password secured systems and negative authentication
(Massachusetts Institute of Technology, 2013)Today's industry, government, and critical infrastructure are dependent on software systems. In their absence, our modern world would come to a stop. Given our dependence, the mounting cyber threat is of critical concern. ...
