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...
A binary tree coding scheme is a bijection mapping a set of binary trees to a set of integer tuples called codewords. One problem considered in the literature is that of listing the codewords for n-node binary trees, such that successive codewords...
A combined analytical and empirical method to define human performance measures is required for effective automated training. In theory, performance measures can be weighted and combined in a single first order equation upon which an automated...
A computer graphics simulation of an aircraft Head-Up Display was designed using an RDS-3000 Ikonas Graphics Processor and a PDP-11/34 host computer system. The software control and display modules were accomplished using Ikonas microcode and...
A computer model of a fin and tube air-to-air heat exchanger is presented. The model incorporates a computational scheme to account for latent effects due to small amounts of moisture in one or both fluid streams. A testing program is described...
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...
A concrete beam is rarely subjected to pure torsion loading. However, in many design applications a beam is subjected to torsional loads in addition to bending and shear loading. The American Concrete Institute has developed a specification for the...
A desirable goal of military simulation training is to provide large scale or joint exercises to train personnel at higher echelons. To help meet this goal, many of the lower echelon combatants must consist of computer generated forces with some...
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 discussion of the Rorschach's validity as a diagnostic tool seems most manageable when validity is addressed not in terms of global personality descriptions, but rather in terms of specific subquestions. This paper investigates the Rorschach's...
A factoring of a graph G = (V,E) is a collection of spanning subgraphs F1, F2, ?, Fk, known as factors into which the edge set E has been partitioned. A dominating set of a graph is a set of nodes such that every node in the graph is either...
A fixed charge model has been developed for a case study of a total energy power plant involving energy demands for chilled water, high temperature hot water, and electrical power. Using a FORTRAN computer program, which employs the Land and Doig...
A formula for the average fade time of the intensity of a spherical optical wave travelling through atmospherica turbulence is developed. The model employed involves isotropic, homogeneous statistics using a lognormal distribution for the...
A formula for the average fade time of the intesity of a plane optical wave traveling through atmospheric turbulence is developed. The model employed involves isotropic, homogeneous statistics using a lognormal distribution for the channel. The...
A Gold code sequence generator suitable for use in a code division multiple access spread spectrum communication application is designed. A dual, single return shift register configuration is used to generate Gold code sequences. The code sequences...
A group of college educated mothers of pre-school children were compared on ratings of the Bem Sex-Role Inventory and the Marital Satisfaction Inventory in order to examine what effect sex-role orientation may have on marital satisfaction in...
A linear programming model has been developed fro a Central Energy Plant which minimizes operational costs for a system involving the generation of chilled water and high temperature hot water plus the generation and/or purchase of electric power...
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...
A methodology is presented for evaluting the performance of database update schemes. The methodology uses the M/Hr/1 queueing model as a basis for this analysis and makes use of the history of how data is used in the database. Parameters have...
