K E E P E R : online conversation support scaffolding modeled after ancient and modern social technologies
(Massachusetts Institute of Technology, 2020)Emergence, when an entity is observed to have properties its parts do not have on their own, is an awe inducing phenomenon seen within nature, complex organization theory, physics, art, and philosophy. Humans can experience ... -
K, Na distribution and unit cell parameters of alkali feldspars.

K-distribution fading models for Bayesian estimation of an underwater acoustic channel
(Massachusetts Institute of Technology, 2011)Current underwater acoustic channel estimation techniques generally apply linear MMSE estimation. This approach is optimal in a mean square error sense under the assumption that the impulse response fluctuations are well ... -
K-shell ionization in collisions of heavy atoms.
(Massachusetts Institute of Technology, 1972) -
K-stability of Log Fano Cone Singularities
(Massachusetts Institute of Technology, 2022-05)In this thesis, we define the 𝛿-invariant for log Fano cone singularities, and show that the necessary and sufficient condition for K-semistability is 𝛿 ≥ 1. This generalizes the result of C. Li and K. Fujita. We also ... -
K-Star rapid rotators and the detection of relatively young multiple K-Star systems
(Massachusetts Institute of Technology, 2014)In this thesis, I searched through the Kepler light curves of 14,440 K-star targets for evidence of periodicities that indicate rapid stellar rotation. Many Kepler M, K, and G stars show modulations in flux due to rotating ... -
K-theoretic Hall algebras for quivers with potential
(Massachusetts Institute of Technology, 2020)Given a quiver with potential (Q, W), Kontsevich-Soibelman constructed a Hall algebra on the cohomology of the stack of representations of (Q, W). As shown by Davison-Meinhardt, this algebra comes with a filtration whose ... -
K-theory and index theory on manifolds with boundary

A Ka-band free-electron laser amplifier

Kac's random walk and coupon collector's process on posets
(Massachusetts Institute of Technology, 2008)In the first part of this work, we study a long standing open problem on the mixing time of Kac's random walk on SO(n, R) by random rotations. We obtain an upper bound mix = O (n2.5 log n) for the weak convergence which ... -
Kairoscope : coordinating time socially
(Massachusetts Institute of Technology, 2010)If everyone says time is relative, why is it still so rigidly defined? There have been many attempts to address the issue of coordinating schedules, but each of these attempts runs into an issue of rigidity: in order to ... -
Kaizen events implementation for cycle time reduction in gauge production line
(Massachusetts Institute of Technology, 2010)This thesis describes the implementation of three Kaizen events designed to improve efficiency on a gauge production line which consists of both semiconductor and mechanical equipment for manufacturing complex products ... -
Kakeya sets and the method of multiplicities
(Massachusetts Institute of Technology, 2009)We extend the "method of multiplicities" to get the following results, of interest in combinatorics and randomness extraction. 1. We show that every Kakeya set (a set of points that contains a line in every direction) in ... -
Kalani : product development and leadership in a new venture
(Massachusetts Institute of Technology, 2018)The development of a start-up creating physical products follows a different path than those working in the digital space. The process of creation requires multiple steps, with many disparate people involved in those steps. ... -
Kaleido : individualistic visual interfaces for software development environments
(Massachusetts Institute of Technology, 2010)Programming, especially programming in the context of art and design, is a process of reconciling and shifting between individual creative thought and rigid conceptual models of code. Despite advances of programming support ... -
Kalman filter estimation of underwater vehicle position and attitude using Doppler velocity aided inertial motion unit
(Massachusetts Institute of Technology, 1994) -
Kalman filter non-linear control law for a gyroscope pulse width modulation torque loop
(Massachusetts Institute of Technology, 1989) -
Kalman filtering for aided inertial navigation system
(Massachusetts Institute of Technology, 1999)This thesis develops a Kalman filter which integrates the inertial navigation system of the Vorticity Control Unmanned Undersea Vehicle (VCUUV) with redundant navigation sensor measurements. The model for the Kalman filter ... -
Kalman filtering of IMU sensor for robot balance control
(Massachusetts Institute of Technology, 2008)This study explores the use of Kalman filtering of measurements from an inertial measurement unit (IMU) to provide information on the orientation of a robot for balance control. A test bed was created to characterize the ... -
Kami : an anarchic approach to distributed computing
(Massachusetts Institute of Technology, 2000)This thesis presents a distributed computing system, Kami, which provides support for applications running in an environment of heterogeneous workstations linked together by a high speed network. It enables users to easily ...
