Mesophase Pitch-Based Carbon Fibers With Carbon Nanotube Reinforcements, Amod A. Ogale, Dan D. Edie, Apparao M. Rao

Clemson Patents

A modified, mesophase pitch-based carbon fiber is disclosed which includes carbon nanotube reinforcements in an amount ranging from about 0.01 percent to about 1.0 percent by weight. Although the reinforcements actually decrease the excellent tensile modulus of the unmodified fiber, they provide a random microstructure, which can decrease brittle failure of the fiber caused by propagation of a flaw.

Synthesis Of Branched Carbon Nanotubes, Apparao M. Rao, Nicholas W. Gothard, Jay B. Gaillard

Clemson Patents

The present invention discloses a relatively simple CVD method for forming branched carbon nanotubes. In general, the method includes adding a dopant to the precursor materials. The dopant can be a material that has a thermodynamically more favorable carbide-forming reaction at the reactor conditions than does the catalyst that is provided to the reactor by a second precursor material. The doped nanoparticles formed in the reactor can adhere to the walls of the developing nanotubes and provide a nucleation site for the development of one or more branches on the nanotube. The nanotubes formed according to the invention can be …

Publications

We present Follow-Up Network for Gamma-Ray Bursts (FUN GRB) Collaboration observations of the optical afterglow of GRB 021211 made between 143 s and 102 days after the burst. Our unique data set includes the earliest filtered detections and color information for an afterglow in the pre-Swift era. We find that the afterglow is best described by (1) a propagation through a wind-swept medium, (2) a cooling break that is blueward of the observed optical frequencies, and (3) a hard electron energy distribution. However, superimposed on this ‘‘standard model’’ behavior we find, one and possibly two, significant chromatic variations during the …

Designs For Wide Band Antennas With Parasitic Elements And A Method To Optimize Their Design Using A Genetic Algorithm And Fast Integral Equation Technique, Chalmers M. Butler, Shawn D. Rogers

Clemson Patents

A method for applying an algorithm to facilitate the design of wideband omnidirectional antennas, and the design of sleeve cage monopole and sleeve helix units includes rapid resolution of a complex relationship among antenna components to yield an optimal system. A genetic algorithm is used with fitness values for design factors expressed in terms to yield optimum combinations. Cage antennas are optimized via a genetic algorithm for operation over a wide band with low VSWR. Genetic algorithms and an integral equation solver are employed to determine the position and lengths of parasitic wires around a cage antenna in order to …

Predicting Residue Contacts Using Pragmatic Correlated Mutations Method: Reducing The False Positives, Petras J. Kundrotas, Emil Alexov

Publications

Background

Predicting residues' contacts using primary amino acid sequence alone is an important task that can guide 3D structure modeling and can verify the quality of the predicted 3D structures. The correlated mutations (CM) method serves as the most promising approach and it has been used to predict amino acids pairs that are distant in the primary sequence but form contacts in the native 3D structure of homologous proteins.

Results

Here we report a new implementation of the CM method with an added set of selection rules (filters). The parameters of the algorithm were optimized against fifteen high resolution crystal …

A Case Study On Grid Performance Modeling, Amy Apon, Baochuan Lu, Larry Dowdy, Frank Robinson, Doug Hoffman, Denny Brewer

Publications

The purpose of this case study is to develop a performance model for an enterprise grid for performance management and capacity planning1. The target environment includes grid applications such as health-care and financial services where the data is located primarily within the resources of a worldwide corporation. The approach is to build a discrete event simulation model for a representative work-flow grid. Five work-flow classes, found using a customized k-means clustering algorithm characterize the workload of the grid. Analyzing the gap between the simulation and measurement data validates the model. The case study demonstrates that the simulation model can be …

"Don't You Mean 'Slaves,' Not 'Servants'?": Literary And Institutional Texts For An Interdisciplinary Classroom, Susanna Ashton

Editor's Note: This article begins a semiregular feature in which contributors analyze "texts" that figure in the daily lives of college English teachers: e.g., syllabi, course descriptions, administrative decrees, departmental bylaws, college Web sites. Your proposals are invited. Here, Susanna Ashton describes how undergraduates in her class on representations of slavery studied the words, sounds, and images they encountered at a historical site on her campus: the former slave plantation of leading antebellum racist John C. Calhoun. She also analyzes how her school depicts this site on the

Electron-Dephasing Time In A Two-Dimensional Spin-Polarized System With Rashba Spin-Orbit Interaction, D C. Marinescu

Publications

We calculate the dephasing time Bof an electron in a two-dimensional system with a Rashba spin-orbit interaction, spin-polarized by an arbitrarily large magnetic field parallel to the layer. B is estimated from the logarithmic corrections to the conductivity within a perturbative approach that assumes weak, isotropic disorder scattering. For any value of the magnetic field, the dephasing rate changes with respect to its unpolarized-state value by a universal function whose parameter is 2EZ=ESOI (EZ is the Zeeman energy, while ESOI is the spin-orbit interaction), confirming the experimental report published in Phys. Rev. Lett. 94, 186805 (2005). In the high-field limit, …

Stress And Fatigue In Foreign Language Professionals: Implications For Global Security, James A. Mccubbin, June J. Pilcher, Thomas W. Britt, Thomas Wallsten

Publications

Information critical to the security of nations is embedded in an array of foreign languages. Foreign language professionals must often analyze complex information from different language sources, and the integrity of their analyses can significantly affect corporate and government decision-making, policy development, and response to world events. Psychological stress and fatigue can degrade the performance of foreign language professionals resulting in errors that may adversely affect security. Optimal design of work organization and work environments, individual stress management training, and augmented cognitive linguistics may facilitate the performance of foreign language professionals. Strategic assessment and management of stress and fatigue in …

From Research Institution To Liberal Arts College: An Interview With Merrily Taylor, Eric C. Shoaf

Publications

This article presents an interview with Merrily E. Taylor, the university librarian of Washington and Lee University in Lexington, Virginia. When asked on the similarities and difference of directing a small college library compared to a large one, Taylor states that it's the two libraries role to the institutional setting which makes them similar while it's their primary mission which makes them different. Taylor believes that her responsibility as a university librarian remains the same whether she is working for a small or large college library, it is the approach of carrying out the responsibilities which spells the difference.

Publications

The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date (z =0.033). We present Very Large Telescope, Liverpool Telescope, and Katzman Automatic Imaging Telescope multi-color photometry of SN 2006aj. This super-nova is found to be subluminous and rapidly evolving. Its early light curve includes an additional wavelength-dependent component, which can be interpreted as shock break-out. We compare the photometric evolution of multi-band light curves with the corresponding properties of the present sample of more than 10 GRB-SNe with precisely known redshifts. Using host-galaxy extinction measure-ments, we derive extinction-corrected GRB-SN luminosities and place SN 2006aj in …

Protcom: Searchable Database Of Protein Complexes Enhanced With Domain-Domain Structures, Petras Kundrotas, Emil Alexov

Publications

The database of protein complexes (PROTCOM) is a compilation of known 3D structures of protein–protein complexes enriched with artificially created domain–domain structures using the available entries in the Protein Data Bank. The domain–domain structures are generated by parsing single chain structures into loosely connected domains and are important features of the database. The database (http://www.ces.clemson.edu/compbio/protcom) could be used for benchmarking purposes of the docking and other algorithms for predicting 3D structures of protein–protein complexes. The database can be utilized as a template database in the homology or threading methods for modeling the 3D structures of unknown protein–protein complexes. …

Neutrino Oscillation Effects On Supernova Light Element Synthesis, Takashi Yoshida, Toshitaka Kajino, Hidekazu Yokomakura, Keichi Kimura, Akira Takamura, Dieter H. Hartmann

Publications

Neutrion oscillations affect light-element synthesis through the v-process in supernova explosions. The 7Li and 11B yields produced in a supernova explosion of a 16.2 M ⊙ star model increase by factors of 1.9 and 1.3 in the case of the large mixing angle solution with a normal mass hierarchy of sin^2 2θ13 >~ 2x10^-3 compared with those without the oscillations. In the case of an inerted mass hierarchy or a nonadiabatic 1-3 mixing resonance, the increment of their yields is much smaller. Neutrino oscillations raise the reaction rates of charged-current v-process reactions in the region outside oxygen-rich layers. The number …
