Any structural analysis which gives stresses and displacements for some predefined structure is governed by some physical domain of loading, geometry and boundary conditions. Let this domain be called the structures "problem space." In applying...
A design for a deep ocean hydrophone is proposed here. The hydrophone's sound sensing element is comprised of a capped end, piezoelectric cylinder. This sound sensing element is encased in an acoustic coupling fluid filled elastomeric boot. A small...
This paper presents a parametric study of the stresses in a matrix near a cylindrical inclusion. The Texas Grain Analysis Program (TEXGAP), a finite element approach, is used to model the problem. Eight different models are investigated which...
Hydrophones used in the ocean produce spurious outputs due to vibration sensitivity which can severly degrade measurement accuracy. Sources of these vibration inputs are ocean surface waves, flow turbulence, and induced mechanical vibration. The...
Radiosity has been used to create some of the most photorealistic computer-generated images to date. The problem, however, is that radiosity algorithms are so computationally and memory expensive that few applications can employ them...
A ramjet inlet duct structure has been designed using nonlinear structural analysis to allow local plastic deformations which result in structural weight reduction. To establish the feasibility of reduced shell thickness, the Lower-Bound Theorem...
This research report documents the various types of Data Acquisition Systems in use for testing jet aircraft engines. The cost trade offs and design considerations are explored for systems which employ a digital computer as the prime...
The development of distributed applications has not progressed as rapidly as its enabling technologies. In part, this is due to the difficulty of reasoning about such complex systems. In contrast to sequential systems, parallel systems give rise to...
The Florida Technological University four-component strain-gage balance is an internally mounted, half-inch diameter balance capable of measuring four components of load: front and rear normal force, axial force, and rolling moment. Measurement of...
NULL Convention Logic (NCL) provides an asynchronous design methodology employing dual-rail signals, quad-rail signals, or other Mutually Exclusive Assertion Groups (MEAGs) to incorporate data and control information into one mixed path. In NCL,...
An absorption principal cooling system, currently proposed for installation and evaluation at the Florida Solar Energy Center (FSEC), is described as a system and modeled through use of "A Transient Simulation Program (TRNSYS)" developed by the...
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...
Less Developed Countries (LDC's) now have a total of about 2.8 billion people, or approximately 70 percent of the total world population. World populations and current energy consumption are such that is all the world's countries came up to the...
The science of synthetic fuel production began in the seventeenth century. However, large-scale production of synthetic fuels started in the early 1900's and, for several decades, gas manufactured from coal significantly contributed to the U.S....
The oscilloscope is undoubtedly one of the most important tools in any electronics shop. Presently there are many relatively inexpensive oscilloscopes available, but triggered sweep capability is still reserved for those oscilloscopes costing more...
In order to better simulate an explosive underwater environment, a new design of the existing explosion driven hydrodynamic conical shock tube has been proposed. This new concept calls for the removal of part of the old tube to accommodate a...
The design of a high speed circuit accepting a bipolar analog signal with a 3db bandwidth of 20 MHZ and an eight bit unipolar gain control signal is presented in this thesis. The system produces the product of these two signals at a rate of one...
The College of Engineering at the University of Central Florida has a flight simulator. This simulator was built as a stand-alone Instrument Flight Rules (IFR) training aid. The college has attempted on several occasions to augment this simulator...
In the design of an elastic structure, a major consideration is the overall stability of the system under axial load or a combination of an axial load and bending moment. In first-order analysis the effects of axial forces on the stiffness...
A trace metal speciation scheme proposed by Batley and Florence (1976) was applied to determine the physiochemical forms of zinc, cadmium, lead, and copper in two Central Florida highway drainage systems. The linearity and limitations of the ASV...
