The Discrete Logarithm Problem And Ternary Functional Graphs, Max F. Brugger, Christina A. Frederick Aug 2007

The Discrete Logarithm Problem And Ternary Functional Graphs, Max F. Brugger, Christina A. Frederick

Mathematical Sciences Technical Reports (MSTR)

Encryption is essential to the security of transactions and communications, but the algorithms on which they rely might not be as secure as we all assume. In this paper, we investigate the randomness of the discrete exponentiation function used frequently in encryption. We show how we used exponential generating functions to gain theoretical data for mapping statistics in ternary functional graphs. Then, we compare mapping statistics of discrete exponentiation functional graphs, for a range of primes, with mapping statistics of the respective ternary functional graphs.


Force-Response Considerations In Ciliary Mechanosensation, Andrew Resnick, Ulrich Hopfer Aug 2007

Force-Response Considerations In Ciliary Mechanosensation, Andrew Resnick, Ulrich Hopfer

Physics Faculty Publications

Considerable experimental evidence indicates that the primary, nonmotile cilium is a mechanosensory organelle in several epithelial cell types. As the relationship between cellular responses and nature and magnitude of applied forces is not well understood, we have investigated the effects of exposure of monolayers of renal collecting duct chief cells to orbital shaking and quantified the forces incident on cilia. An exposure of 24 h of these cells to orbital shaking resulted in a decrease of amiloride-sensitive sodium current by ∼60% and ciliary length by ∼30%. The sensitivity of the sodium current to shaking was dependent on intact cilia. The …

Coagulation Effects On Aerosol Dynamics Along An Isothermal Vertical Flat Plate, Chang-Bin Huang, Cherng-Shing Lin, Shih-Cheng Wang Aug 2007

Coagulation Effects On Aerosol Dynamics Along An Isothermal Vertical Flat Plate, Chang-Bin Huang, Cherng-Shing Lin, Shih-Cheng Wang

Journal of Marine Science and Technology–Taiwan

Aerosol dynamic behavior in a turbulent flow field is investigated in this study. The flow field is a natural convection boundary layer flow adjacent to a heated or cooled vertical flat plate. The main computational method is based on a boundary layer type solution combining the flow field and sectional aerosol simulation. The SIMPLE alogrithm is adopted to solve the flow continuity, momentum, energy, and aerosol concentration equations. Various aerosol dynamic transport and removal mechanisms, including fluid convection, Brownian motion, gravitational settling, thermophoretic drift, and coagulation of aerosols, are considered in the simulation model. Aerosol coagulation effects on particle transport …


Optimization Of Perforated Doublelayer Absorbers Using Simulated Annealing, Min-Chie Chiu, Ying-Chun Chang, Long-Jyi Yeh, Tian-Syung Lan Aug 2007

Effects Of Surface Roughness On Porous Inclined Slider Bearings Lubricated With Micropolar Fluids, N.B. Naduvinamani, T.V. Biradar Aug 2007

Effects Of Surface Roughness On Porous Inclined Slider Bearings Lubricated With Micropolar Fluids, N.B. Naduvinamani, T.V. Biradar

Journal of Marine Science and Technology–Taiwan

This paper describes a theoretical analysis of the effect of surface roughness on the hydrodynamic lubrication of one-dimensional porous inclined slider bearings with micropolar fluids. To account for more realistic situations of the non-uniform rubbing of the bearing surfaces, it is assumed that, the probability density function for the random variable characterizing the surface roughness is asymmetrical with non-zero mean. The averaged modified Reynolds type equation is derived and the closed form expressions for the bearing characteristics are obtained. The numerical computations of the results show that, the performance of the porous inclined slider bearing is improved for the micorpolar …

Trap, Escape And Vision Integration: Key Adaptive Challenges Of Leadership In Conflict, Tin Muang Than Aug 2007

Trap, Escape And Vision Integration: Key Adaptive Challenges Of Leadership In Conflict, Tin Muang Than

Student Scholarship

The paper identifies trap, escape and vision integration as adaptive challenges to leadership in conflict, particularly in the context of Burma, where military government and elected parties have been in political impasse since 1990 elections. International sanctions and constructive engagement strategies have failed to bring the parties to the table. Burmese opposition leaders have found that other parties are simply unwilling to begin negotiations. In this context, what can opposition leaders do when a major actor of conflict is reluctant to enter into negotiation? Concepts are mainly drawn from theories of leadership, conflict and group. The research objective is to …


Phase Transition In U(1) Configuration Space: Oscillons As Remnants Of Vortex-Antivortex Annihilation, M. Gleiser, J. Thorarinson Aug 2007

Phase Transition In U(1) Configuration Space: Oscillons As Remnants Of Vortex-Antivortex Annihilation, M. Gleiser, J. Thorarinson

Dartmouth Scholarship

We show that the annihilation of vortex-antivortex pairs can lead to very long-lived oscillon states in 2d Abelian Higgs models. The emergence of oscillons is controlled by the ratio of scalar and vector field masses, β=(ms/mv)2 and can be described as a phase transition in field configuration space with critical value βc≃0.13(6)±2: only models with βO(β)∼|β−βc|o, where O is an order parameter indicating the presence of oscillons and o=0.2(2)±2 is the critical exponent.

The Effect Of Nonlinear Propagation On Near-Field Acoustical Holography, Micah Raymond Shepherd Aug 2007

The Effect Of Nonlinear Propagation On Near-Field Acoustical Holography, Micah Raymond Shepherd

Theses and Dissertations

Near-field acoustical holography (NAH) has been used extensively for acoustical imaging of infinitesimal-amplitude (or small-amplitude) sources. However, recent interests are in the application of NAH to image finite-amplitude (or high-amplitude) sources such as jets and rockets. Since NAH is based on linear equations and finite-amplitude sources imply nonlinear effects, which cause shock formation and consequently an altered spectral shape, a feasibility study is carried out to determine the effect of nonlinear propagation on NAH. Jet and rocket sources typically have a distinct spectral shape resembling a ‘haystack’ and center frequencies varying from 30 to 300 Hz. To test the effect …


The Shift From Defined Benefit Pensions To 401(K) Plans And The Pension Assets Of The Baby Boom Cohort, James Poterba, Steven Venti, David A. Wise Aug 2007

The Shift From Defined Benefit Pensions To 401(K) Plans And The Pension Assets Of The Baby Boom Cohort, James Poterba, Steven Venti, David A. Wise

Dartmouth Scholarship

The rise of 401(k) plans and the decline of defined benefit plans will have an important effect on the wealth of future retirees. Changing demographic structure also will affect the aggregate stock of retirement wealth. We project the stock of assets held in retirement plans and the average retirement saving of retirees through 2040. Our projections show large increases in wealth at retirement, especially if the returns on corporate equities are comparable with historical returns. Retirement wealth will grow, however, even if equity returns fall substantially below their historical level.

Confidence Intervals For Population Size In A Capture-Recapture Problem., Xiao Zhang Aug 2007

Confidence Intervals For Population Size In A Capture-Recapture Problem., Xiao Zhang

Electronic Theses and Dissertations

In a single capture-recapture problem, two new Wilson methods for interval estimation of population size are derived. Classical Chapman interval, Wilson and Wilson-cc intervals are examined and compared in terms of their expected interval width and exact coverage properties in two models. The new approach performs better than the Chapman in each model. Bayesian analysis also gives a different way to estimate population size.


A Statistical Evaluation Of Algorithms For Independently Seeding Pseudo-Random Number Generators Of Type Multiplicative Congruential (Lehmer-Class)., Robert Grisham Stewart Aug 2007

A Statistical Evaluation Of Algorithms For Independently Seeding Pseudo-Random Number Generators Of Type Multiplicative Congruential (Lehmer-Class)., Robert Grisham Stewart

Electronic Theses and Dissertations

To be effective, a linear congruential random number generator (LCG) should produce values that are (a) uniformly distributed on the unit interval (0,1) excluding endpoints and (b) substantially free of serial correlation. It has been found that many statistical methods produce inflated Type I error rates for correlated observations. Theoretically, independently seeding an LCG under the following conditions attenuates serial correlation: (a) simple random sampling of seeds, (b) non-replicate streams, (c) non-overlapping streams, and (d) non-adjoining streams. Accordingly, 4 algorithms (each satisfying at least 1 condition) were developed: (a) zero-leap, (b) fixed-leap, (c) scaled random-leap, and (d) unscaled random-leap. Note …


Tricyclic Steiner Triple Systems With 1-Rotational Subsystems., Quan Duc Tran Aug 2007

Tricyclic Steiner Triple Systems With 1-Rotational Subsystems., Quan Duc Tran

Electronic Theses and Dissertations

A Steiner triple system of order v, denoted STS(v), is said to be tricyclic if it admits an automorphism whose disjoint cyclic decomposition consists of three cycles. In this thesis we give necessary and sufficient conditions for the existence of a tricyclic STS(v) when one of the cycles is of length one. In this case, the STS(v) will contain a subsystem which admits an automorphism consisting of a fixed point and a single cycle. The subsystem is said to be 1-rotational.

Pleistocene Peccaries From Guy Wilson Cave, Sullivan County, Tennessee., April Season Nye Aug 2007

Pleistocene Peccaries From Guy Wilson Cave, Sullivan County, Tennessee., April Season Nye

Electronic Theses and Dissertations

Descriptive and taphonomic analyses of undescribed Pleistocene Tayassuidae from Guy Wilson Cave within the East Tennessee State University and McClung Museum collections revealed a MNI of 16 Platygonus compressus and 2 Mylohyus from left femora and isolated teeth, respectively. Linkage between upper dentition and species identification is suggested by comparing Mylohyus fossilis to M. nasutus from other Pleistocene-aged sites. Long-bone NISP and age profiles show a predominance of Platygonus adults. Tayassuidae upper canines, likely Platygonus, suggest sexual dimorphism. Long bones were analyzed for carnivore damage and utilization revealing light utilization similar to that caused by modern wolves. Long bone …
