Variable Frequency Controlled Zero-Voltage Switching Single-Ended Current-Fed Dc-To-Ac Converter With Output Isolation, Issa Batarseh, Kasemsan Siri Jun 1997

Variable Frequency Controlled Zero-Voltage Switching Single-Ended Current-Fed Dc-To-Ac Converter With Output Isolation, Issa Batarseh, Kasemsan Siri

UCF Patents

A modified DC-to-AC power converter accomplishes power transfer to a load with electrical isolation, zero-voltage and zero-current switching, using a transformer core resetting mechanism. The power converter contains two switching devices, a main device connected in parallel and a secondary device connected in series with a transformer primary winding. A secondary winding of the transformer is connected through a two-port resonant link circuit to a resistive load. Zero-voltage switching and proper transformer-core resetting are achieved from the resonance that exists between the parasitic capacitance of the secondary switching device and the magnetization inductance of the transformer. A transformer leakage inductance …

The Effect Of Varying Temperature, Flux And Pretreatment On The Microfiltration Of Lake Michigan Water, Karen Linda Kopp Jan 1997

The Effect Of Varying Temperature, Flux And Pretreatment On The Microfiltration Of Lake Michigan Water, Karen Linda Kopp

Retrospective Theses and Dissertations

This study investigated microfiltration of Lake Michigan Water for the production of drinking water. A 60 gpm Memcor microfiltration pilot plant was operated for nine months at Manitowoc, Wisconsin to determine and model the performance characteristics of a microfiltration pilot plant for varying surface water conditions. Statistical regression and modeling was used to determine and develop quantitative relationships between time of operation and several operational variables for water quality and productivity. Modifications of Darcy's Law and flux decline data were used to develop a model relating temperature and flux to cleaning frequency. Statistical hypothesis testing and associated modeling were used …

Continuum Limit Of Lattice Approximation Schemes, Carl M. Bender, Alexander Tovbis Jan 1997

Continuum Limit Of Lattice Approximation Schemes, Carl M. Bender, Alexander Tovbis

Faculty Bibliography 1990s

Boundary-layer perturbation theory problems are inherently singular. However, it is known that discretizing the problem by introducing a lattice may convert such problems into regular perturbation problems. The singular nature of boundary-layer problems is then relegated to and hidden in the continuum limit, the subtle limit in which the lattice spacing tends to zero. If the lattice is introduced cavalierly, then extrapolating to zero lattice spacing gives a sequence of extrapolants that at first approaches the correct limit and then veers off, thereby revealing the asymptotic nature of such problems. However, discretizing the problem following the procedures described here yields …

Transform Coding Of Signals Using Approximate Trigonometric Expansions, Qurban A. Memon, Takis Kasparis Jan 1997

Transform Coding Of Signals Using Approximate Trigonometric Expansions, Qurban A. Memon, Takis Kasparis

Faculty Bibliography 1990s

For signal representation it is always preferred that a signal be represented using a minimum number of parameters. in any transform coding scheme, the central operation is the reduction of correlation and thereby with appropriate coding of the transform coefficients, allows data compression to be achieved. The objective of data encoding is to transform a data array into a statistically uncorrelated set. This step is typically considered a "decorrelation" step, because in the case of unitary transformations the resulting transform coefficients are relatively uncorrelated. Most unitary transforms have the tendency to compact the signal energy into relatively few coefficients. The …


An Approach To The Synthesis Of Biological Tissue, Jannick P. Rolland, Robin N. Strickland Jan 1997

An Approach To The Synthesis Of Biological Tissue, Jannick P. Rolland, Robin N. Strickland

Faculty Bibliography 1990s

Mathematical phantoms developed to synthesize realistic complex backgrounds such as those obtained when imaging biological tissue, play a key role in the quantitative assessment of image quality for medical and biomedical imaging. We present a modeling framework for the synthesis of realistic tissue samples. The technique is demonstrated using radiological breast tissue. The model employs a two-component image decomposition consisting of a slowly, spatially varying mean-background and a residual texture image. Each component is synthesized independently. The approach and results presented here constitute an important step towards developing methods for the quantitative assessment of image quality in medical and biomedical …


Transfer Of Momentum And Torque From A Light Beam To A Liquid, A. Yu. Savchenko, N. V. Tabiryan, B. Ya. Zel'dovich Jan 1997

Transfer Of Momentum And Torque From A Light Beam To A Liquid, A. Yu. Savchenko, N. V. Tabiryan, B. Ya. Zel'dovich

Faculty Bibliography 1990s

Refraction or absorption of light results in the force and torque, i.e., transfer of momentum and angular momentum from light to the medium. In transversely inhomogeneous beams, the force per unit volume f may have curlf not equal 0 leading to flow or to nonthermal and nongravitational convection in liquids. The force and the torque in scattering systems are as strong as in absorbing materials and may allow one to carry out experiments avoiding thermal effects. Nonlinear optical response of liquid crystals due to this convection is discussed.


Dynamics Of Low-Dimensional Dipolar Systems, J. M. Sun, Weili Luo Jan 1997

Dynamics Of Low-Dimensional Dipolar Systems, J. M. Sun, Weili Luo

Faculty Bibliography 1990s

Time decays of low-dimensional magnetic dipoles with anisotropic energy barriers were studied theoretically. We found that the dynamic behaviors are interaction specific. For a chain with ferromagnetic coupling, a single mode dominates and the decay is essentially exponential. For antiferromagnetic coupling, the dynamics can be characterized by two distinct groups of time scales. The spectrum results in a plateau in the decay of remanent magnetization. This novel behavior differs from the prediction of the mean-field theory. For a two-dimensional rectangular lattice, a transition between the bimodal decay and a quasilogarithmic decay occurs when the ratio of length to width varies.
