A Systems and Control Perspective of CPS Security
(20190122)Abstract—The comprehensive integration of instrumentation, communication, and control into physical systems has led to the study of CyberPhysical Systems (CPS), a field that has recently garnered increased attention. ... 
Tables for solution of the heatconduction equation with a timedependent heating rate
(Cambridge, Mass. : M.I.T. Heat Transfer Laboratory, [1962], 1962)Tables are presented for the solution of the transient onedimensional heat flow in a solid body of constant material properties with the heating rate at one boundary dependent on time. These tables allow convenient and ... 
Theoretical Estimates of Mechanical Properties of the Endothelial Cell Cytoskeleton
(Biophysical Society, 1996)Current modeling of endothelial cell mechanics does not account for the network of Factin that permeates the cytoplasm. This network, the distributed cytoplasmic structural actin (DCSA), extends from apical to basal ... 
Thermal boundary layer development in dispersed flow film boiling
(Cambridge, Mass. : Heat Transfer Laboratory, Dept. of Mechanical Engineering, Massachusetts Istitute of Technology, [1982], 1982)Dispersed flow film boiling consists of a dispersion of droplets which are carried over a very hot surface by their vapor. This process occurs in cryogenic equipment and wet steam turbines. It is also of interest in the ... 
Thermal contact conductance in a vacuum
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1965], 1965)The object of this work is to develop analytically equations by which one could predict the thermal contact conductance between contiguous surfaces operating in a vacuum environment. In this work the solution to the problem ... 
Thermal contact resistance
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1966], 1966)This work deals with phenomena of thermal resistance for metallic surfaces in contact. The main concern of the work is to develop reliable and practical methods for prediction of the thermal contact resistance for various ... 
Thermal contact resistance in a nonideal joint
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1971], 1971)The contact conductance at an interface can be determined by knowing the material and surface properties and the interfacial pressure distribution. This pressure distribution can be influenced strongly by the roughness of ... 
Thermal contact resistance with nonuniform interface pressures
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1970], 1970)This work considers the effect of roughness and waviness on interfacial pressure distributions and interfacial contact resistance. It is shown that for moderate roughness the contour area could be substantially different ... 
Thermal nonequilibrium in dispersed flow film boiling in a vertical tube
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1966], 1966)The departure from thermal equilibrium between a dispersed liquid phase and its vapor at high quality during film boiling is investigated, The departure from equilibruim is manifested by the high resistance to heat transfer ... 
The thermodynamics of bubbles
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1956], 1956)This paper outlines those concitions annanded by the laws of thermodynamics for equilibriza betwoen the vapor in a bubble and the surrounding liquid and then employs these concepts with a nucleation theory in an atteapt ... 
Threedimensional flow structures and vorticity control in fishlike swimming
(Cambridge University Press, 2002)We employ a threedimensional, nonlinear inviscid numerical method, in conjunction with experimental data from live fish and from a fishlike robotic mechanism, to establish the threedimensional features of the flow ... 
Towards Resilient CyberPhysical Energy Systems
(20170314)In this paper, we develop a systemofsystems framework to address cyberphysical resilience, the ability to withstand the combined presence of both cyber attacks and physical faults. This framework incorporates a deﬁnition ... 
Transition boiling heat transfer from a horizontal surface
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1960], 1960)An experiment, utilising a condensing fluid as the heat source, was performed to determine the heat flux vs. temperature difference curve for transition pool boiling from a horisontal surface. The boiling cure was determined ...
