A mathematical model is presented for the problem of determining the two-dimensional temperature distribution resulting from the discharge of a heated effluent into a shallow, quiescent receptacle. The physical model ofr the problem is the...
This paper provides a brief historical discussion of the development of time division low level multiplexing techniques and especially emphasizes MOS-FET multiplexers currently being implemented. Error sources which may affect system accuracy and...
The maintenance and supply system of the Atlantic Missile Range Communications Network (AMRCN) is modeled to determine the optimum level of men and parts which must be available at Cape Kennedy, the source of supply, in order to minimize the level...
The equations of underwater acoustics that relate to the signal excess noise received by a transducer are rigorously described in the acoustical literature. The objective of this paper is to examine some underwater acoustic equations and ascertain...
This research report discusses a binary power generation and salt water distillation cycle that aws the subject of a feasibility study at Florida Technological University. The thermodynamic equations are derived and the results of a parametric...
A covariant form of Hamilton's Principle of Stationary Action is formulated and used to solve the general eiconal equation describing the wave function of light in a medium carrying ultrasound. Tensor notation is reviewed and the tensor form of...
The purpose of this paper was to design a simplified wind tunnel force balance for use in elementary aerodynamics/wind tunnel laboratory courses. The applied loads and moments were determined to be as follows: The design lift force is ± 20 lbs,...
A computer model of a flat plate solar collector has been devised. The model is able to simulate most common types of collectors, with up to three transparent covers of any material. Using primarily equations available from the literature the...
Mass transit vehicles in formal rail service frequently attain speeds which can excited carbody oscillations (primary hunting), as well as sustained alteral oscillations of the trucks (secondary hunting). The carbody motions have been shown to...
Eddy current inspection methods are used extensively in industry for the nondestructive testing of a wide varity of materials and product applications. The general theory of eddy current inspection is described. Equations defining the depth of...
A computer model has been developed to analyze the flow of a dissociating gas through a porous metal matrix. The program predicts the transient temperature distributions through the coolant gas and matrix along with the pressure distribution and...
Solar cells have traditionally been used for a direct sunlight to energy conversion, and there has been relatively little investigation into their use as a low data rate optical detector. This report summarizes the results of experimental work to...
The Ebers-Moll model, which is applicable to static or quasi-static conditions, is used as a basis for developing a simple method for the evaluation of harmonic distortion generated in bipolar transistor amplifiers. The Ebers-Moll equations are...
A mathematical model is derived to provide quasi-steady state predictions of the performance of a high pressure hydraulic supply system, using equations which govern the physical processes as opposed to equations which match input-output...
A method is presented which permits the measure of nose tip recession of re-entry vehicles and advanced terminal interceptors by employing a double choked flow coolant gas system. Recession of the tip results in an increased exit flow area which...
In this paper the effects of inertia are explored for the case of a thermal excitation applied on the surface of an infinitely long, solid circular cylinder. The linear uncoupled field equations for a homogeneous, isotropic, thermoelastic medium...
A digital computer model has been developed to simulate the kinetic response of a thermal pressurized water reactor power plant. The program is capable of predicting core power and plant temperature variations which result from distrubances due to...
A bench scale laboratory ozonator was constructed and determined to produce 27 mg O3/hr. A contacting system and experimental procedure was developed to approximate a mass balance of 0, 1, 2, 4, 8 and 16 ppm were applied to raw and magnesium...
The boundary integral technique was implemented in a computer code for the general static analysis of three dimensional elastic solids. The was based on a formulation of the problem in which the governing boundary equation is developed from the...
Given a transfer function for a differential equation model, an approach for obtaining a solution is by way of bilinear transformation. The bilinear transform approach is a numberical integration scheme which gives a discrete approximation to the...
