An electromechanical shutter mechanism capable of achieving shutter speeds up to 50 m/sec was designed, constructed and tested. An exploding wire was used to generate a cylindrically imploding blast wave. The input energy ...

Four algorithms of dual matrices for function minimization introduced in Ref. 1 are tested through several numerical examples. Three quadratic functions and five nonquadratic functions are investigated. For quadratic ...

A Mach-Zehndcr interferometer using a helium-neon laser and a high speed closed-open-closed shutter was designed and constructed in the present plasma facility in the Department of. Mechanical and Aerospace Engineering and ...

This thesis considers the problem of minimizing a function f(x) subject to a constraint cp(x) = 0, where f is a scalar quantity, x an n-vector, and cp a q-vector, with q being less than n. The penalty function method is ...

Linearized partial differential equations for incompressible fluid temperature dynamics in pipes and single-pass heat exchangers are derived. Laplace transform methods are employed to obtain temperature transfer functions ...

The nine quadratically convergent algorithms for function minimization appearing in Ref. 1 are tested through numerical examples. Both a quadratic function and a nonquadratic function are investigated. For the quadratic ...

Laboratory tests were carried out to study the removal of drilled particles in a well borehole simulated annulus. The main objectives of these tests were to determine the effect of varying: (1) the particle size and particle ...

The problem of extremizing a function f(xl subject to the constraint cc(x) = 0 is considered. Here, f is a scalar, x an n-vector, and cp a q-vector, where 0 < q < n. This problem is transformed into that of minimizing the ...

A detailed study of the slip lines in deformed ordered and disordered Cu3Au single crystals has been carried out. The slip lines have been observed via optical metallography and by the two-step replica technique and ...

The performance of a porous plate sublimator with uniform heater plate temperature has been analyzed and tested in a previous investigation. A method of applying this analysis to a fluid heated sublimator is presented. ...
