DSpace is a joint development project of the Massachusetts Institute of Technology Libraries and Hewlett-Packard Company. Its mission is to establish a library service to capture, distribute, and preserve the digital, intellectual output of the MIT community. We are developing…

Thin wires are attached on the outer surface and parallel to the axis of a smooth
circular cylinder in a steady cross-stream, modelling the effect of protrusions and
attachments. The impact of the wires on wake properties, and vortex-induced loads

This thesis traces the development of American bacteriology during the first quarter of the twentieth century. While bacteriology experienced a period of rapid growth, an enduring disciplinary anxiety equally characterized the field. In particular, bacteriologists feared increasing specialization and conceptual…

We have studied nine laser transitions in Ba vapor at wavelengths
between 1.13 and 3.05 micrometer. Three of these laser lines have not
been reported previously. The relative intensities of the four strongest
transitions (1.13, 1.50, 2.55, and 2.92 micrometer)…

We have derived a broad, deterministic model of the steady-state actin cycle that includes its major regulatory
mechanisms. Ours is the first model to solve the complete nucleotide profile within filaments, a feature that determines the
dynamics and geometry of…

Polymethine laser dyes which fluoresce in the near infrared in
organic solvents generally exhibit poor temporal stability at room
temperature. Two typical laser-pumped polymethine dyes in aqueous
solutions containing nonionic surfactants are investigated. Temporal
stability was improved 20-fold, as compared…

Presented in this paper is a robust control scheme for
controlling systems with time delays. The scheme is based on the Smith
controller and the LQG/LTR (Linear Quadratic Gaussian/Loop Transfer
Recovery) methodology. The methodology is applicable to undenvater
vehicle systems…

The lasing efficiencies and photochemical stabilities of laser
dyes useful in the 710-1080-nm spectral region have been investigated
using a Q-switched ruby laser pumping source. The measured bleaching
rates P defined as the probability of irreversible decomposition of a dye

The estimation of the heave, pitch, roll, sway, and yaw motions of a DD-963 destroyer is studied, using Kalman filtering
techniques, for application in VTOL aircraft landing.

The governing equations are obtained from hydrodynamic considerations in the form of…
