Development Of Fpga Based Low-Power Digital Pulse Height Fitting, Santosh Hooli

Graduate Theses, Dissertations, and Problem Reports (ETD)

Energetic ion analyzers and mass spectrometers commonly produce electronic pulses whose amplitude and time depend on the energy, mass, and direction of an incoming ion. Analysis of the nanosecond scale timing and amplitude of these approximately 10-12C charge pulses has required complex, fast analog electronics. Given recent advances in digital electronics, it seems likely that converting much of the analysis to digital form will result in a simpler, lower cost, and lower power electron package. The aim of the thesis is to develop an algorithm to fit a 500 ns long noisy voltage pulse obtained from an ion analyzer to …

Efficient Simulation Of Communication Systems On A Desktop Grid, Raja Sekhar Katuri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Simulation is an important part of the design cycle of modern communication systems. As communication systems grow more sophisticated, the computational burden of these simulations can become excessive. The need to rapidly bring systems to market generally precludes the use of a single computer, and drives a demand for parallel computation. While this demand could be satisfied by the development of dedicated infrastructure, a more efficient option is to harness the unused computational cycles of underutilized desktop computers located throughout the organization.;In this thesis, a new paradigm for parallelizing communication simulations is proposed and developed. A desktop grid is created …

Image Data Compression By Using Multiwavelete For Color Image, Eanas Y. Al-Tae'e, Mariam A. Ali

Baghdad Science Journal

Thousand pictures requires a very large amount of storage. So the science of digital image compression is used to reduce the storage requirements for these images Wavelet transforms require filters that combine a number of desirable properties, such as orthogonally and symmetry. The design possibilities for wavelets are limited because they can not simultaneously passes all these desirable properties. The relatively new field of multi-wavelets show promise in removing some of the limitations of wavelets, multiwavelets offer more design options and hence can combine all desirable transform features. The few previously published results of multiwavelet based image compression have mostly …

The Smith-Mundt Act's Ban On Domestic Propaganda: An Analysis Of The Cold War Statute Limiting Access To Public Diplomacy, Edward L. Carter, Allen W. Palmer

Faculty Publications

For more than fifty years, the U.S. Code has authorized the federal government to disseminate messages about America to international audiences. For at least thirty years, federal law has also prohibited those international propaganda messages from being disseminated within the United States. Given the realities of the acceleration and dispersion of information flow across international borders in the twenty-first century, a ban on dissemination of information that is tied to geographic boundaries raises both practical and policy issues. The domestic dissemination ban may have outlived its usefulness and relevance. Further, futile enforcement of the statute contradicts general U.S. policy promoting …
