Active Vorticity Control in a Shear Flow Using a Flapping Foil
(Cambridge University Press, 1994)It is shown experimentally that free shear flows can be substantially altered through direct control of the large coherent vortices present in the flow. 
Adaptive Control of a Generic Hypersonic Vehicle
(20160310)This paper presents an adaptive augmented, gainscheduled baseline LQRPI controller applied to the Road Runner sixdegreeoffreedom generic hypersonic vehicle model. Uncertainty in control effectiveness, longitudinal ... 
Adaptive Output Feedback Based on ClosedLoop Reference Models for Hypersonic Vehicles
(20160309)This paper presents a new method of synthesizing an output feedback adaptive controller for a class of uncertain, nonsquare, multiinput multioutput systems that often occur in hypersonic vehicle models. The main challenge ...

(20150407)This paper presents a new method of synthesizing an output feedback adaptive controller for a class of uncertain, nonsquare, multiinput multioutput systems that often occur in hypersonic vehicle models. The main challenge ... 
Adaptive OutputFeedback Control for A Class of MultiInputMultiOutput Plants with Applications to Very Flexible Aircraft
(20151007)A dominant presence of parametric model uncertainties necessitates an adaptive approach for control of very flexible aircraft (VFA). This paper proposes an adaptive controller that includes a baseline design based on ... 
Adaptive OutputFeedback Control with ClosedLoop Reference Models and Applications to Very Flexible Aircraft
(20150407)This paper proposes an adaptive controller for a class of multiinput multioutput (MIMO) plants where the number of outputs is larger than the number of inputs, an example of which is veryflexible aircraft (VFA). A ... 
American Society for Echocardiography Software Suite for Verification and
(Institute of Electrical and Electronic Engineers, 1995)The imminent balloting of the draft DICOM 3.0 module on ultrasound represents a major step forward in the progress of digital storage formats for echocardiography. In this paper, we discuss a software suite soon to be ... 
Analysis of Slow Convergence Regions in Adaptive Systems
(20151007)We examine convergence properties of errors in a class of adaptive systems that corresponds to adaptive control of linear timeinvariant plants with state variables accessible. We demonstrate the existence of a sticking ...

Areas of contact and pressure distribution in bolted joints
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1970], 1970)When two plates are bolted (or riveted) together these will be in contact in the immediate vicinity of the bolt heads and separated beyond it. The pressure distribution and size of the contact zone is of considerable ... 
Boiling and condensation in a liquidfilled enclosure
(Cambridge, Mass. : M.I.T. Heat Transfer Laboratory, [1971], 1971)A combined experimental and analytical investigation of boiling and condensation in a liquidfilled enclosure, with water and Freon 113 as the working fluids, is described. The operating characteristics of a boiling system, ... 
Bubble growth rates in boiling
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1956], 1956)The conditions determining the growth rate of a bubble on a surface in boiling are considered and a mathematical model framed in the light of these conditions. The growth rate is then calculated for bubbles growing under ... 
The bubblyslug transition in a high velocity two phase flow
(Cambridge, Mass. : M.I.T. Division of Sponsored Research, [1964], 1964)A possible mechanism for the transition between bubbly and slug flow is proposed and tested in a simulated slug flow system. No sudden collapse of slug flow with increasing velocity is found and it is concluded that: a. ... 
Burnout in forced convection nucleate boiling of water
(Cambridge, Mass. : M.I.T. Heat Transfer Laboratory, [1957], 1957)Data are presented for burnout in forced coivection nucleate boiling of water at pressures above 500 psia. A dimensionless correlation is devised for. the M.I.T. data which is found to be valid for certain recent data ... 
Calculation of Dynamic Motions and Tensions in Towed Underwater Cables
(Institute of Electrical and Electronic Engineers, 1994)A matrix method for mooring system analysis is extended to address the dynamic response of towed underwater systems. Key tools are equivalent linearization and small perturbation theory, and a pitching towfish model. ...
