A Design Report on a Servo Controlled Inertial Sensor Test Fixture
This report discusses the design of a servo controlled positioning system for remote control positioning of inertial sensors while under high acceleration test in a centrifuge. A rotating fixture and an electronic control panel was built for this...
Test Methods for Evaluating Performance of Solar Units
This report is concerned with the performance of solar hot water units for laboratory and field use. A solar unit is defined as a system consisting of a collector, storage tank, piping system and controls. Older unites typically employ the...
Vapor phase oxidation of chloropropenes over heterogeneous catalyst systems
Propylene Dichloride (PDC) is a byproduct of several Dow processes. The thermal cracking of PDC produces l - cis-chloropropene , I - trans-chloropropene, 2- chloropropene , and allyl chloride . By oxidizing the 1 - and 2-chloropropenes to 3- and 2-...
An investigation into a least squares method for image registration
One of the problems associated with the automatic image processing of satellite photographs such as weather maps is the need for image registration; that is, the fitting of a map that has some translational and rotational bias to a known data base....
The Population Dynamics and Distribution of CORBICULA MANILENSIS (Philippi) in a Spring-fed Central Florida Stream
Asiatic clams (Corbicula manilensis Philippi) were smapled at twelve stations randomly located along a 16-km stretch of the Wekiva River, Florida, every three months fro August 1976 to June 1977. Clams were found at most stations. Their abundance...
Design and Analysis of an Explosive Driven Hydrodynamic Conical Shock Tube
An explosive driven, water filled, concial shock tube was designed and evaluated regarding its ability to amplify a charge weight and to produce hydrodynamic spherical shock waves. The results show that the shock waves in the tube are essentially...
The Effect of pH on Methane Production from Dairy Cattle Manure
The effects of pH upon methane production from anaerobic digestion of dairy cattle manure were investigated. One liter digesters were maintained by daily adjustment at the following pH levels: 7.6, 7.0, 6.0, 5.5, and 5.0. After 33 weeks of...
Preparation of 2,5-Diaryl-1,3,4-Oxadiazoles
This report regards the research conducted in the synthesis of 2,5-disubstituted-1,3,4-oxadiazoles as potential insecticides which are closely related to the known insecticide DOWCO 416R, 2,5-bis(2,4-dichlorophenyl)-1,3,4-oxadiazole. The following...
Part I: The Synthesis of New Potential Insecticides. Part II: New Aromatic Nucleophililic Subsitution Reactions, Fluoroalkoxylation and N,N-Dimethylamination
A series of routes are described for the synthesis of new potential insecticides which are symmetrical or asymmetrical similogs of 2,5-Bis (dichloropheny1)-1,3,4-oxadiazole and its precursor diacyl hydrazine. Also two new aromatic nucleophilic...
Effects on Iron and Cobalt on Methane Production from Dairy Cattle Manure
The effects of iron and cobalt on methanogenesis from dairy cattle manure were studied. Four-liter digestors with 3-liter working volumes were charged daily with dairy manure (4.5% W/V volatile solids) to achieve a 3-day retention time. Digestors...
Forced Convective Critical Heat Flux Modeling for Tubes and Rod Bundles
This thesis presents a model for predicting the forced convective critical heat flux (CHF) for water over a wide range of thermal-hydraulic conditions which might be encountered during normal and accident operations of a light water nuclear...
Evaluation of a Binary Spatial Light Modulator Correlator Using Time-Domain Polarity Coincidence Correlation Theory
Time-domain Polarity Coincidence Correlators (PCC) have been studied for the possible extension of these theories to the spatial-domain in the context of an optical PCC. The existing body of knowledge has been found to be inadequate for direct...
Enterface : a novella
A computer screen places each of us in an interface and virtual reality provides a totally simulated environment, a virtual world that we can enter. Enterface is a novella that examines the question first posed by Michael Heim: How far can we...
