Weakly supervised semantic parsing for Linear Temporal Logic
(Massachusetts Institute of Technology, 2020)We train a semantic parser to discover latent meaning representations that can be used for the execution of natural language commands. We focus on the difficult domain of commands with a temporal aspect, whose semantics ... -
Weaponized disclosure : the feedback effect of disclosure externalities
(Massachusetts Institute of Technology, 2017)Information about one firm has the potential to affect the stock price of another firm. I investigate whether managers recognize this potential and strategically alter their disclosure decisions when doing so is beneficial. ... -
Weapons brokers and policy entrepreneurs : Congress and the strategic policy community during the Reagan era
(Massachusetts Institute of Technology, 1992) -
Weapons innovation and joint system development : a case study of the Joint STARS program
(Massachusetts Institute of Technology, 1997) -
Weapons-grade plutonium disposition : an alternate immobilization strategy
(Massachusetts Institute of Technology, 1997) -
Wear modeling with sensitivity to lubricant chemistry
(Massachusetts Institute of Technology, 2007)The life of an automotive engine is often limited by the ability of its components to resist wear. Zinc dialkyl-dithiophosphate (ZDDP) is an engine oil additive that reduces wear in an engine by forming solid antiwear films ... -
Wear of contact tips in gas-metal arc welding of titanium
(Massachusetts Institute of Technology, 1984) -
Wear of high speed, high current density slip ring materials at elevated temperatures
(Massachusetts Institute of Technology, 1981) -
Wearable and automotive systems for affect recognition from physiology
(Massachusetts Institute of Technology, 2000)Novel systems and algorithms have been designed and built to recognize affective patterns in physiological signals. Experiments were conducted for evaluation of the new systems and algorithms in three types of settings: a ... -
A wearable blood pressure sensor using oscillometric photoplethysmography and micro accelerometers
(Massachusetts Institute of Technology, 2007)Monitoring arterial blood pressure (ABP) with a sensor virtually imperceptible to the wearer, for continuous periods of weeks, months, or years, could prove revolutionary in the diagnosis and treatment of chronic hypertension ... -
Wearable computing and contextual awareness
(Massachusetts Institute of Technology, 1999)Computer hardware continues to shrink in size and increase in capability. This trend has allowed the prevailing concept of a computer to evolve from the mainframe to the minicomputer to the desktop. Just as the physical ... -
A wearable health monitor to aid Parkinson disease treatment
(Massachusetts Institute of Technology, 2003) -
A wearable heart monitor at the ear using ballistocardiogram (BCG) and electrocardiogram (ECG) with a nanowatt ECG heartbeat detection circuit
(Massachusetts Institute of Technology, 2013)This work presents a wearable heart monitor at the ear that uses the ballistocardiogram (BCG) and the electrocardiogram (ECG) to extract heart rate, stroke volume, and pre-ejection period (PEP) for the application of ... -
Wearable Lab and BioFab on body : towards closed-loop bio-digital human augmentation
(Massachusetts Institute of Technology, 2020)We explore the vision of closed-loop bio-digital interfaces for human augmentation, where the bio-digital system allows for both sensing and writing biological information to the body. Current-generation wearable devices ... -
Wearable multiple sensor acquisition device
(Massachusetts Institute of Technology, 2003)The wearable multiple sensor acquisition device is targeted as the primary sensor hub for the next revision of the MIThril wearable computer architecture. The device provides 3-axis acceleration sensing, infrared transmission ... -
A wearable navigation system for augmenting guide dog object detection
(Massachusetts Institute of Technology, 2019)In this thesis, I discuss the design, construction and evaluation of a wearable object detection system for blind users to avoid collisions. Blind people rely upon tools such as guide dogs to navigate the world around them. ... -
A wearable system that learns a kinematic model and finds structure in everyday manipulation by using absolute orientation sensors and a camera
(Massachusetts Institute of Technology, 2005)This thesis presents Duo, the first wearable system to autonomously learn a kinematic model of the wearer via body-mounted absolute orientation sensors and a head-mounted camera. With Duo, we demonstrate the significant ... -
A wearable Transcranial Doppler ultrasound phased array system
(Massachusetts Institute of Technology, 2017)Transcranial Doppler (TCD) sonography is a specialized ultrasound technique that enables measurement of blood ow velocity from the basal intracerebral vessels. Use of TCD sonography is highly compelling as a diagnostic ... -
A wearable, wireless sensor system for sports medicine
(Massachusetts Institute of Technology, 2008)This thesis describes a compact, wireless, wearable system that measures, for purposes of biomechanical analysis, signals indicative of forces, torques and other descriptive and evaluative features that the human body ... -
Wearable-assisted social interaction as assistive technology for the blind
(Massachusetts Institute of Technology, 2014)This work presents an end-to-end wearable system designed to learn and assist its (potentially blind) wearers with daily social interactions. In particular, it visually identifies nearby acquaintances and provides timely, ...
