Data Driven Calculations Histories To Minimize Ieee-755 Floating-Point Computational Error, Lawrence E. Shafer

CCE Theses and Dissertations

The widely implemented and used IEEE-754 Floating-point specification defines a method by which floating-point values may be represented in fixed-width storage. This fixed-width storage does not allow the exact value of all rational values to be stored. While this is an accepted limitation of using the IEEE-754 specification, this problem is compounded when non-exact values are used to compute other values. Attempts to manage this problem have been limited to software implementations that require special programming at the source code level. While this approach works, the problem coder must be aware of the software and explicitly write high-level code specifically …

Applying Security Risk Management To Internet Connectivity In K-12 Schools And School Districts, Carol C. Woody

CCE Theses and Dissertations

Internet connectivity has been added to the classrooms of United States (U.S .) K-12 schools, but recognition of the security risks and related management responsibilities to address increased risk exposure is not apparent. Providing a sufficient level of access for K-12 students to learn through exploration and experimentation needs to be balanced with sufficient limitations to minimize the risk of technically proficient participants inflicting harm through school resources. Problems of inappropriate use such as adjusting grades, tampering with work of other students, and defacing Web sites by K-12 students are already appearing in U.S. newspapers. In addition, the growing level …

Excimer Emission From Cathode Boundary Layer Discharges, Mohamed Moselhy, Karl H. Schoenbach

Bioelectrics Publications

The excimer emission from direct current glow discharges between a planar cathode and a ring-shaped anode of 0.75 and 1.5 mm diameter, respectively, separated by a gap of 250 μm, was studied in xenon and argon in a pressure range from 75 to 760 Torr. The thickness of the “cathode boundary layer” plasma, in the 100 μm range, and a discharge sustaining voltage of approximately 200 V, indicates that the discharge is restricted to the cathode fall and the negative glow. The radiant excimer emittance at 172 nm increases with pressure and reaches a value of 4 W/cm² for …

Age Differences In Central (Semantic) And Peripheral Processing: The Importance Of Considering Both Response Times And Errors, Philip A. Allen, Martin D. Murphy, Miron Kaufman, Karen E. Groth, Ana Begovic

Physics Faculty Publications

In this project we examined the effect of adult age on visual word recognition by using combined reaction time (RT) and accuracy methods based on the Hick–Hyman law. This was necessary because separate Brinley analyses of RT and errors resulted in contradicting results. We report the results of a lexical decision task experiment (with 96 younger adults and 97 older adults). We transformed the error data into entropy and then predicted RT by using entropy values separately for exposure duration (thought to influence peripheral processes) and word frequency (thought to influence central processes). For exposure duration, the entropy–RT functions indicate …

Faculty Publications

Cross sections for e+ p neutral current deep inelastic scattering have been measured at a center-of-mass energy of √s = 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 63.2 pb -1. The double-differential cross section, d2σ/ dxdQ2, is presented for 200 GeV2 < Q2 < 30 000 GeV2 and for 0.005 < x < 0.65. The single-differential cross sections dσ/dQ2, dσ/dx and dσ/dy are presented for Q2 > 200 GeV2. The effect of Z-boson-exchange is seen in dσ/dx measured for Q2 > 10 000 GeV2. The data presented here were combined with ZEUS e+ p neutral current data taken at √s = 300 GeV and the structure function F2em was extracted. All results agree well with the predictions of the Standard Model.

Anatomy Of A Chaotic Attractor: Subtle Model-Predicted Patterns Revealed In Population Data, Aaron A. King, R. F. Costantino, J. M. Cushing, Shandelle M. Henson, Robert A. Desharnais, Brian Dennis

Faculty Publications

Mathematically, chaotic dynamics are not devoid of order but display episodes of near-cyclic temporal patterns. This is illustrated, in interesting ways, in the case of chaotic biological populations. Despite the individual nature of organisms and the noisy nature of biological time series, subtle temporal patterns have been detected. By using data drawn from chaotic insect populations, we show quantitatively that chaos manifests itself as a tapestry of identifiable and predictable patterns woven together by stochasticity. We show too that the mixture of patterns an experimentalist can expect to see depends on the scale of the system under study.

Asymmetry Of Above-Threshold Ionization Of Metal Clusters In Two-Color Laser Fields: A Time-Dependent Density-Functional Study, H. S. Nguyen, A. D. Bandrauk, Carsten A. Ullrich

Physics Faculty Research & Creative Works

A spherical jellium model and time-dependent density functional theory for two-color ultrashort laser pulses as a function of phase difference between two fields were used to calculate the above threshold ionization (ATI) spectra of small metal clusters. ATI spectra and the ionized electrons fluxes were obtained in the two opposite directions of the linearly polarized laser fields. It is found that ATI spectra has long energy plateaus, with cutoffs up to 30-40 times the ponderomotive energy Up. However, no extended plateaus were observed in high-harmonic generation spectra.

Variational Considerations In The Study Of Carrier Transport In Organic Crystals, V. M. Kenkre, Paul Ernest Parris

Physics Faculty Research & Creative Works

A variational approach is used to investigate consequences of electron-phonon interactions between a charge carrier and multiple (specifically two) phonon branches. Phase diagrams are obtained and the nature of the transition from undressed to dressed phases of the carrier is studied with their help. No sharp transition between singly dressed and doubly dressed phases occurs. The effective carrier bandwidth, reduced by strong coupling to the high-frequency branch is found to be stable with respect to small to intermediate values of additional coupling to the low-frequency branch. This finding lends support to transport calculations based on the idea that carriers in …
