Autoreducibility, Mitoticity, And Immunity, Christian Glaßer, Mitsunori Ogihara, A. Pavan, Alan L. Selman, Liyu Zhang

Computer Science Faculty Publications

We show the following results regarding complete sets. • NP-complete sets and PSPACE-complete sets are polynomial-time many–one autoreducible.

• Complete sets of any level of PH, MODPH, or the Boolean hierarchy over NP are polynomial-time many–one autoreducible.

• EXP-complete sets are polynomial-time many–one mitotic.

• If there is a tally language in NP ∩ coNP − P , then, for every ϵ > 0 , NP-complete sets are not 2 n ( 1 + ϵ ) -immune.

These results solve several of the open questions raised by Buhrman and Torenvliet in their 1994 survey paper on the structure of complete sets.

Controlling Spin-Polarized Electron Transport Through A Molecule: The Role Of Molecular Conformation, L. Senapati, Ranjit Pati, S. C. Erwin

Department of Physics Publications

We investigate theoretically the spin-polarized electron transport through a complex organic molecule coupled to magnetic contacts. Our focus is on how low-energy deformations of the molecule affect the current-voltage characteristics and the magnetotransport of this molecular-scale device. We find that fairly modest deformations, costing only a few tens of meVs, can substantially change the tunneling current—by factors of 2 or more. Such deformations have still larger impact on the magnetoresistance, with small changes in molecular conformation even leading to changes in the sign of the magnetoresistance.

Second Year Evaluation Of The Systematic Effects Of The Dc Voucher Program, Marcus A. Winters, Jay P. Greene

School Choice Demonstration Project

While publicly sponsored school voucher programs are primarily intended to impact the lives of those who take advantage of the service, they may also have consequences for the larger community. In particular, voucher programs could affect the performance of public schools by altering their resources and incentives; they could alter the demographics of both public and private schools; they could provide new opportunities for students to attend private schools or simply supplement the behavior of students who would have attended private schools regardless of the program. Regardless of the impact of such programs on the few students who are able …

Pre-Conference Proceedings Of The Focus Symposium On Representation Of Context In Software Data → Information → Knowledge, Collaborative Agent Design Research Center

Collaborative Agent Design (CAD) Research Center

For the past 20 years commercial corporations and government agencies have suffered under the limitations of stove-piped computer software applications that function as discrete entities within a fragmented data-processing environment. In the United States of America (US) military services, lack of interoperability has been identified by numerous think tanks, advisory boards, and studies, as the primary information systems problem (e.g., Army Science Board 2000, Air Force SAB 2000 Command and Control Study, and NSB Network-Centric Naval Forces 2000). Yet, despite this level of attention, all attempts to achieve interoperability within the current data-centric information systems environment have proven to be …

Optical Monitoring System With Molecular Filters, Robert A. Lodder, John Carberry

Pharmaceutical Sciences Faculty Patents

An optical monitoring system for determining the constituents of a sample or specimen. An absorption spectrum is obtained from a sample and is passed through one or more filters having a specified absorption spectrum defined by a single atom or a compound. If the filter's absorption spectrum is included in the sample's absorption spectrum, then the sample contains that atom or compound. The apparatus includes a switching assembly that sequentially places one or more filters into the light path to determine if the subject atom or compound is contained in the sample.

Nevada Risk Assessment/Management Program (Nramp) – Phase 2: Quarterly Progress Report April 1, 2007 Through June 30, 2007, Klaus J. Stetzenbach

Nevada Risk Assessment/Management Program

Work conducted this quarter consisted of continuing the detailed data and information acquisition; review of the received document contents, and interpretation of significance in light of previous DOE documents. Much of the effort was devoted to reconciling inconsistencies and contradictions in both the primary data bases and in and among the DOE published documents. These review and reconciliation efforts included regular telephone and e-mail correspondence, as well as in-person discussions with DOE NVO personnel at the April DOE Generator Conference in Las Vegas. Reconciliation efforts continued with frequent (daily) exchanges on the inventory data sets, and the engineering descriptions of …

Parents’ And Teachers’ Beliefs About Parental Involvement In Schooling, Mary Kelly Haack

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Parental involvement in schooling is critical for children’s academic success. Despite its importance, parental involvement appears to be discouragingly low. Attribution theory may provide an explanation for perceived limited parental participation in specific activities to support their children's schooling and for strained parent/teacher relations. This study identified and compared the causal attributions made by teachers and parents for a hypothetical situation in which a parent was not sufficiently involved in their elementary aged child’s schooling. In addition, differences in attributions based on the education level of the parent were examined. Participants for the study were 80 regular education teachers in …

Knowledge Management Enterprise Services (Kmes): Concepts And Implementation Principles, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The purpose of this paper is to present concepts and implementation principles related to the design and development of reusable software services that are capable of assisting users at the operational level. Knowledge Management Enterprise Services (KMES) are an implementation of the service-oriented architecture paradigm, with a focus on the exchange of data within the meaningful context of a particular application (i.e., knowledge) domain. This requires a KMES service to incorporate a high level representation of this knowledge domain in the form of an ontology that is shared among all collaborating services within the application environment and at the same …

Alternative Paths To Intelligent Systems, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

This paper examines the three prevalent approaches to Artificial Intelligence (AI), namely symbolic reasoning systems, connectionist systems, and emergent systems based on the principles of the subsumption theory. Distinguished by their top-down and bottom-up mechanisms all three approaches have strengths and weaknesses. While the logical reasoning approach is precise and well supported by mathematical theories and procedures, it is constrained by a largely predefined representational model. Connectionist systems, on the other hand, are able to recognize patterns even if these patterns are only similar and not identical to the patterns that they have been trained to recognize, but they have …

Enhancing The Face Of Service-Oriented Capabilities, Kym J. Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

With today’s focus toward discoverable web services, Service-Oriented Architectures (SOA) are becoming increasingly prevalent. To support an effective interaction between services and their clientele, the sophistication of the interface, or face, such services present is of critical importance. Without a rich, expressive nature, such services struggle to satisfy the industry promises of reuse, composability, and reduced inter-component dependencies. Especially relevant for domain-oriented applications, services must present sufficient levels of expression to allow for an effective exchange of relevant context. Further, such communication should be offered in an asynchronous manner to promote both work flow efficiency and limited coupling.

The production of energetic neutrons in ep collisions has been studied with the ZEUS detector at HERA. The neutron energy and pT2 distributions were measured with a forward neutron calorimeter and tracker in a 40 pb-1 sample of inclusive deep inelastic scattering (DIS) data and a 6 pb-1 sample of photoproduction data. The neutron yield in photoproduction is suppressed relative to DIS for the lower neutron energies and the neutrons have a steeper pT2 distribution, consistent with the expectation from absorption models. The distributions are compared to HERA measurements of leading protons. The neutron energy and transverse-momentum distributions in DIS …

Sampling Methods In Ray-Based Global Illumination, David Cline

Theses and Dissertations

In computer graphics, algorithms that attempt to create photographic images by simulating light transport are collectively known as Global Illumination methods. The most versatile of these are based on ray tracing (following ray paths through a scene), and numerical integration using random or quasi-random sampling. While ray tracing and sampling methods in global illumination have progressed much in the last two decades, the goal of fast and accurate simulation of light transport remains elusive. This dissertation presents a number of new sampling methods that attempt to address some of the shortcomings of existing global illumination algorithms. The first part of …

Creating Culturally Relevant Techonological Operas In An Urban School, Dianna Isaac-Johnson

Dissertations

The project described in this study developed due to the gap in achievement between African-American and white students. As music teacher I noticed my urban students could rap all the words of popular songs. Therefore I incorporated the use of technology with an authentic need to learn reading, writing, and lyric development for science and history content within a "hip-hop opera". This study details the instructional sequence, in which students watched musical performances, learned songs with a karaoke machine, and wrote new lyrics for the songs based on history and science material. I combined the students' lyrics into new versions …

Infrastructure Hardening: A Competitive Co-Evolutionary Methodology Inspired By Neo-Darwinian Arms Races, Travis Service, Daniel R. Tauritz, William M. Siever

Computer Science Faculty Research & Creative Works

The world is increasingly dependent on critical infrastructures such as the electric power grid, water, gas, and oil transport systems, which are susceptible to cascading failures that can result from a few faults. Due to the combinatorial complexity in the search spaces involved, most traditional search techniques are inappropriate for identifying these faults and potential protections against them. This paper provides a computational methodology employing competitive coevolution to simultaneously identify low-effort, high-impact faults and corresponding means of hardening infrastructures against them. A power system case study provides empirical evidence that our proposed methodology is capable of identifying cost effective modifications …

Tuning The Ferromagnetism Of One-Dimensional Fe ∕ Pt ∕ Fe Multilayer Barcode Nanowires Via The Barcode Layer Effect, Puspamitra Panigrahi, Ranjit Pati

Department of Physics Publications

Using first-principles density functional theory, we have predicted equilibrium structures and electronic and magnetic properties of one-dimensional ferromagnetic Fe∕Pt∕Fe multilayer barcode nanowires. By increasing the thickness of the Pt layer and consequently reducing the thickness of the Fe layer in the nanowire in the ferromagnetic configuration, we found that the average magnetic moment per iron atom, μ_av, increases monotonically with an ∼1∕N(Fe) dependence, where N(Fe) is the number of Fe layers. The monotonic increase in average magnetic moment is attributed to the change in magnetic moment at the Fe-Pt interface, and a simple model is …
