Testimonial Poetry In East European Post-Totalitarian Literature, Albena Lutzkanova-Vassileva

CLCWeb: Comparative Literature and Culture

In her article, "Testimonial Poetry in East European Post-Totalitarian Literature," Albena Lutzkanova-Vassileva reexamines the belief that postmodern literature and deconstructive writing have parted literary and theoretical discourse from reality, thereby obstructing and annihilating our access to history. Lutzkanova-Vassileva exemplifies her prognosis in an inquiry into post-totalitarian and postmodern Bulgarian literature and its texts of poetry. Born in the turmoil of communism's debacle, the analysis is an attempt to illustrate that, contrary to denying reference, postmodernism solely rejects the reduction of reference to a world that is perceptible and cognitively masterable. Rethinking what many have seen as a self-referential literature, with …

Participation Equality: Measurement Within Collaborative Electronic Environments-A Three Country Study, Roberto W. Zmud, Roberto J. Mejias, Bruce A. Reinig, Isabel M. Martinez-Martinez

Purdue CIBER Working Papers

While the engendering of participation equality is generally viewed as a desirable group process attribute, findings from prior empirical research are both inconsistent and inconclusive regarding the measurement of participation equality within collaborative electronically supported environments. One explanation for this inconsistency lies in the manner in which the “participation equality” construct has been studied and measured. Results of analyses performed across three distinct national cultures utilizing 86 experimental groups and over 660 participants from the United States, Hong Kong and Spain are presented with recommendations for future research involving the participation equality construct. This is a first paper in a …

Consensus Evidence Evaluation In Resuscitation Research: Analysis Of Type I And Type Ii Errors, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

Objective: This paper addresses the following statistical question: ‘if genuine improvements in cardiopulmonary resuscitation (CPR) were discovered that doubled the probability of resuscitation success in a series of randomized clinical trials, would they be recognized and incorporated into consensus guidelines?’ Methods: Statistical powers for hypothetical individual clinical trials comparing experimental and control CPR were computed as a function of the study N when the true probabilities for immediate survival, 24 h survival, and discharge survival in the experimental group were twice those in the control group. Next, the binomial distributions describing the numbers of statistically significant studies in a series …

Simulating Quasi-Ballistic Transport In Si Nanotransistors, Kausar Banoo, Jung-Hoon Rhew, Mark S. Lundstrom, Chi-Wang Shu, Joseph W. Jerome

Department of Electrical and Computer Engineering Faculty Publications

Electron transport in model Si nanotransistors is examined by numerical simulation using a hierarchy of simulation methods, from full Boltzmann, to hydrodynamic, energy transport, and drift-diffusion. The on-current of a MOSFET is shown to be limited by transport across a low-field region about one mean-free-path long and located at the beginning of the channel. Commonly used transport models based on simplified solutions of the Boltzmann equation are shown to fail under such conditions. The cause for this failure is related to the neglect of the carriers' drift energy and to the collision-dominated assumptions typically used in the development of simplified …

Biomechanics Of Heading A Soccer Ball: Implications For Player Safety, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

To better understand the risk and safety of heading a soccer ball, the author created a set of simple mathematical models based upon Newton’s second law of motion to describe the physics of heading. These models describe the player, the ball, the flight of the ball before impact, the motion of the head and ball during impact, and the effects of all of these upon the intensity and the duration of acceleration of the head. The calculated head accelerations were compared to those during presumably safe daily activities of jumping, dancing, and head nodding and also were related to established …

Bridgman Crystal Growth Of An Alloy With Thermosolutal Convection Under Microgravity Conditions, J. E. Simpson, S V. Garimella, H. C. Degroh Iii, R. Abbaschian

CTRC Research Publications

The solidification of a dilute alloy (bismuth-tin) under Bridgman crystal growth conditions is investigated. Computations are performed in two dimensions with a uniform grid. The simulation includes the species concentration, temperature and flow fields, as well as conduction in the ampoule. Fully transient simulations have been performed, with no simplifying steady state approximations. Results are obtained under microgravity conditions for pure bismuth, and for Bi-0.1 at.% Sn and Bi-1.0 at.% Sn alloys, and compared with experimental results obtained from crystals grown in the microgravity environment of space. For the Bi-1.0 at.% Sn case the results indicate that a secondary convective …

Real-Time Determination Of Soil Type, Water Content, And Density Using Electromagnetics, Vincent P. Drnevich, Chih-Ping Lin, Quanghee Yi, Janet Elaine Lovell

JTRP Technical Reports

The primary objective of this study was to explore the potential use of electromagnetic characteristics of soils using the Time Domain Reflectometry (TDR) technique to identify physical properties of soils. Three fundamental studies in this exploration are the frequencydependent electromagnetic properties of soils, the wave propagation in a TDR system, and the inverse analyses of TDR waveforms. The three-phase model for soils was extended to a four-phase model so as to account for the interface effect and hence the soil fineness. The physical parameters of the four-phase model are related to the frequency-dependent dielectric permitivity of the soil through a …

Theoretical Structure Of Dynamic Gtap, Elena Ianchovichina, Robert Mcdougall

GTAP Technical Papers Archive

This paper documents the foreign asset ownership and investment theory of the dynamic GTAP model (GTAP-Dyn). The new investment theory offers a disequilibrium approach to modeling endogenously international capital mobility. It permits a recursive solution procedure, a feature that allows easy implementation of dynamics into any static AGE model without imposing limitations on the model's size. The method involves treating time as a variable, not as an index. Having time as a variable allows the construction of dynamic GTAP with minimum modifications to the existing structure of GTAP, by separating the theory of static GTAP from the length of run.

An Access Protocol To Provide Qos In Wireless :Networks, Xin Liu, Edwin K. P. Chong, Ness B. Shroff

Department of Electrical and Computer Engineering Technical Reports

In wireless networks, contention-and-reservation schemes provitle promising implementations of packet switching, which efficiently multiplexes different classes of traffic. In this report, we present an access scheme to satisfy the QoS requirements for two classes of traffic during the contention-based communicat,ion. In this algorithm, different classes of users contend with other users for resources based on controlled class-dependent permission probabilities. We prove that our algorithm is stable for a large class of arrival processes. Under certain QoS requirements, we derive an upper-bound for the throughput for a general class of random access algorithms. We show that the throughput of our algorithm …

Efficient Balance-And-Truncate Model Reduction For Large Scale Systems , Venkataramanan Balakrishnan, Qing Su, Cheng-Kok Koh

Department of Electrical and Computer Engineering Technical Reports

We present efficient implement at ions of the balanceand- truncate model reduction technique for large-scale systems. The key observation that distinguishes our approach is that Krylov subspace methods (Arnoldi and Lanczos) directly yield approximate low-rank square roots1 of the system Gramians; the balancing transformation can be then constructed from these square roots, obviating the need for solving any Lyapunov equations. In addition, the order of the reduced model is not fixed a priori as with some existing methods, but is determined from the problem data. Numerical simulations show t,hat our approach performs very well over a range of examples, and …
