Multi-Level Decomposition Of Probabilistic Relations, Stanislaw Grygiel, Martin Zwick, Marek Perkowski

Complex Systems Faculty Publications and Presentations

Two methods of decomposition of probabilistic relations are presented in this paper. They consist of splitting relations (blocks) into pairs of smaller blocks related to each other by new variables generated in such a way so as to minimize a cost function which depends on the size and structure of the result. The decomposition is repeated iteratively until a stopping criterion is met. Topology and contents of the resulting structure develop dynamically in the decomposition process and reflect relationships hidden in the data.

A Performance Study Of Lam And Mpich On An Smp Cluster, Brian Patrick Kearns

Dissertations and Theses

Many universities and research laboratories have developed low cost clusters, built from Commodity-Off-The-Shelf (COTS) components and running mostly free software. Research has shown that these types of systems are well-equipped to handle many problems requiring parallel processing. The primary components of clusters are hardware, networking, and system software. An important system software consideration for clusters is the choice of the message passing library.

MPI (Message Passing Interface) has arguably become the most widely used message passing library on clusters and other parallel architectures, due in part to its existence as a standard. As a standard, MPI is open for anyone …

Conflict Emergence And Escalation In Interactive International Dyads, David Todd Kinsella, Bruce M. Russett

Political Science Faculty Publications and Presentations

We examine whether the conditions affecting initial expressions of hostility are similar to those affecting militarized disputes. Analyzing dyadic interactions during the years 1951–1992, we estimate a model to take into account selection effects and check it against another allowing conjunctive causation. Both provide close approximations to theoretical models of the conflict process and yield similar results. We confirm Kant’s belief that all states are subject to the realist conditions of interstate competition that makes disputes likely, but that liberal influences, if present, can constrain the escalation of such disputes to war. Several influences on the conflict process have nonmonotonic …

Seizing The Moment: Creating A Changed Society And University Through Outreach, Judith A. Ramaley

Public Administration Faculty Publications and Presentations

This conference is built on two very interesting premises; first, that university outreach can change society and second, that outreach can also change the university. What is the mechanism by which this mutual influence can occur? What does the university offer the community, and what does the community offer the university? The short answer is--the opportunity to learn in the company of others in a situation where learning has consequences.

The Role Of Trust, Leader-Member Exchange, And Organizational Justice In Employee Attitudes And Behaviors: A Laboratory And Field Investigation, Rudolph Joseph Sanchez

Dissertations and Theses

The study of interpersonal relationships continues to be a major focus of theory and research in a wide array of disciplines. The present research examined one of the most prevalent and significant interpersonal relationships in the workplace context—the dyadic relationship between a supervisor and a subordinate. This research examined the relationships between trust, quality of the leader-member exchange relationship (LMX; a measure of the quality of the dyadic relationship), perceived organizational justice, and several employee attitudes and behaviors that are important to individual workers and the organizations in which they work.

Data were collected in both laboratory and field settings. …

A New Approach To Robot’S Imitation Of Behaviors By Decomposition Of Multiple-Valued Relations, Uland Wong, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

Relation decomposition has been used for FPGA mapping, layout optimization, and data mining. Decision trees are very popular in data mining and robotics. We present relation decomposition as a new general-purpose machine learning method which generalizes the methods of inducing decision trees, decision diagrams and other structures. Relation decomposition can be used in robotics also in place of classical learning methods such as Reinforcement Learning or Artificial Neural Networks. This paper presents an approach to imitation learning based on decomposition. A Head/Hand robot learns simple behaviors using features extracted from computer vision, speech recognition and sensors.

Tri-Met's Experience With Automatic Passenger Counter And Automatic Vehicle Location Systems, James G. Strathman

Center for Urban Studies Publications and Reports

The Tri-County Metropolitan Transportation District of Oregon (Tri-Met) is one of about 30 metropolitan transit agencies that have deployed both automatic vehicle location (AVL) and automatic passenger counter (APC) systems (Casey, 1999). These technologies are important components of the agency’s new automated bus dispatching system (BDS). The AVL and APC systems at Tri-Met recover comprehensive operations and passenger activity data at the bus stop level that is archived for later analysis. The agency has gained a reputation as an industry leader in the areas of data archiving and the application of archived data to performance monitoring and analysis.

Logic Synthesis For Regular Layout Using Satisfiability, Marek Perkowski, Alan Mishchenko

Electrical and Computer Engineering Faculty Publications and Presentations

In this paper, we propose a regular layout geometry called 3×3 lattice. The main difference of this geometry compared to the known 2×2 regular layout geometry is that it allows the cofactors on a level to propagate to three rather than two nodes on the lower level. This gives additional freedom to synthesize compact functional representations. We propose a SAT-based algorithm, which exploits this freedom to synthesize 3×3 lattice representations of completely specified Boolean functions. The experimental results show that the algorithm generates compact layouts in reasonable time.

The Other Side Of The Tracks: The Archaeology And History Of A Virginia City, Nevada Neighborhood, Julie Marie Schablitsky

Dissertations and Theses

Archaeologists and historians have conducted a limited number of 19th century western neighborhood studies. The small number of inquiries into the urban past has left research on western working and middle class neighborhoods, along with their ethnic and class composition, relatively untouched by modern scholars. Although eastern immigrant neighborhood studies by historic archaeologists are currently increasing, western immigrant neighborhood research projects continue to be underrepresented in the literature. Perceiving an absence of western urban neighborhood studies, an intensive study on an ethnically heterogeneous working and middle class neighborhood was conducted in Virginia City, Nevada.

The community was situated adjacent to …

Content Aware Request Distribution For High Performance Web Service: A Performance Study, Robert M. Jones

Dissertations and Theses

The World Wide Web is becoming a basic infrastructure for a variety of services, and the increases in audience size and client network bandwidth create service demands that are outpacing server capacity. Web clusters are one solution to this need for high performance, highly available web server systems. We are interested in load distribution techniques, specifically Layer-7 algorithms that are content-aware. Layer-7 algorithms allow distribution control based on the specific content requested, which is advantageous for a system that offers highly heterogenous services. We examine the performance of the Client Aware Policy (CAP) on a Linux/Apache web cluster consisting of …

Microbial Composition Of Near-Boiling Silica-Depositing Thermal Springs Throughout Yellowstone National Park, Carrine E. Blank, Sherry L. Cady, Norman R. Pace

Geology Faculty Publications and Presentations

The extent of hyperthermophilic microbial diversity associated with siliceous sinter (geyserite) was characterized in seven near-boiling silica-depositing springs throughout Yellowstone National Park using environmental PCR amplification of small-subunit rRNA genes (SSU rDNA), large-subunit rDNA, and the internal transcribed spacer (ITS). We found that Thermocrinis ruber, a member of the order Aquificales, is ubiquitous, an indication that primary production in these springs is driven by hydrogen oxidation. Several other lineages with no known close relatives were identified that branch among the hyperthermophilic bacteria. Although they all branch deep in the bacterial tree, the precise phylogenetic placement of many of these lineages …

Further Examination Of Moore's Law With Data Envelopment Analysis, Timothy R. Anderson, Rolf Färe, Shawna Grosskopf, Lane Inman, Xiaoyu Song

Engineering and Technology Management Faculty Publications and Presentations

Although it has stood the test of time for over 30 years, Moore's Law addresses but a single aspect of microprocessor design. As a proxy for technology, the number of transistors in an integrated circuit represents a limited perspective on the technology as a whole. Anderson et al. proposed a set of metrics by which to measure a technology, and a means to measure its progress over time utilizing data envelopment analysis. In this revised model, the assumption of state of the art (SOA) on product release is dropped, technical progress is measured iteratively over time, the effective time elapsed …

Environmental Middle School Making The Connection: Locally Grown Food And The Portland Public Schools' Meal Program, Paul Bender, Daniela Brod, Lauren Maloney, April Siebenaler, David Stocker

Master of Urban and Regional Planning Workshop Projects

A recent "farms to school" movement designed to expand the range and quantity of local foods, especially produce, has taken root across the U.S, with support from the United States Department of Agriculture. After finding a suitable client school willing to introduce this idea in Portland, this project, identifies incremental and feasible steps that can be taken toward including more locally gown food into the Environmental Middle School's meal service. The main objectives of this project are:

• To increase the availability of locally grown foods at EMS, and ultimately in the Portland Public Schools meal service program
• To encourage food …
