The vertical plate in laminar free convection: Effects of leading and trailing edges and discontinuous temperature
(Birkhäuser-Verlag; Springer Science+Business Media, 1976-09)
For laminar free-convection flow past a heated vertical plate of finite length, the local asymptotic flow structure is studied in regions where the boundary-layer equations do not provide a correct approximation at large ...
An electromagnetic forcing device
(Kluwer Academic Publishers; Society for Experimental Mechanics, Inc. ; Springer Science+Business Media, 1978-05)
The paper describes the drawbacks of an electromagnetic forcing device, of the type commonly used to study forced vibration of structures, and presents details of a feedback control system designed to overcome them. The ...
Non-linear vibrations of three-layer beams with viscoelastic cores, II: Experiment
(Elsevier, 1978-11-08)
Experimental results are presented for large amplitude, forced motion of damped, three-layer beams. The beams are constructed with a viscoelastic material constrained between stiff, elastic, outer layers. The sandwich beam ...
Optimum coasting flight in a horizontal plane
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-12)
Busemann's concept of optimum altitude for rectilinear coasting flight has been extended to flight in a horizontal plane. The reachable domain of a vehicle in coasting flight in a horizontal plane, starting from an initial ...
Functional differential equations and age dependent population growth
(Elsevier, 1972-08)
Growth equations are established for a population of individuals that have fixed age dependent reproduction and mortality rates. Equations are obtained both for the population density and for the numerical size of the ...
Electrical conductance time constants for freely decaying arcs
(Springer-Verlag, 1973-02)
Electrical conductance time constants for the early stages of free decay after current modulation have been calculated from experimental measurements on a 5 mm diameter cascade arc at atmospheric pressure. The time constants ...
Analytical solutions of a class of optimum orbit modifications
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1970-03)
This paper presents the complete analytical solution of several fundamental problems in orbital correction. The initial orbit is represented by a given point in the phase space, while the final orbit is constrained to stay ...
Optimal aerodynamic control by matched asymptotic expansions
(Elsevier, 1976)
This paper presents the solution for the optimal lift and bank modulation of a reentry vehicle using the method of matched asymptotic expansions. The solution, which contains all effects of aerodynamic, gravitational, and ...
