The major obstacle to widespread parallel programming of multiprocessors is the lack of a convenient parallel programming system. PPSE (Parallel Programming Support Environment) is a unified approach to parallel programming. Parallax is developed as a component of PPSE based on ELGDF which is a graphical language for designing parallel programs....
Pattern matching is the process of comparing two objects to see if they are similar to each other. Objects can be physical objects, situations, facts or events. The criteria of matching can be exact or partial. Traditional pattern matching systems rely on exact matches, in which a small set of...
Multimedia networking is one of the most exciting developments in today's Internet. Streaming technology; which allows the player to start playing audio/video data immediately instead of waiting for the entire file to be downloaded, presents an attractive vehicle for the distribution of multimedia content over the Internet. However, transmitting real-time...
In this project we examine the features of object oriented programming languages that make them most likely languages of choice for implementing simulations. Three simulations of a bank, hospital, and livestock farm scenarios were implemented in the language C++ in order to demonstrate how Object-Oriented languages are used in constructing...
An execution of a database system is considered correct if its net effect is as if transactions were executed serially, and such an execution is called serializable. In this short paper we show that the serializability test problem can be reduced to a simple pebbling problem. Our characterization is intuitive...
Programming style plays an important role in program understanding and maintenance. Studies [Par83] have shown that as much as one- half of a maintenance programmer's time is spent in activities related to understanding the program. Program understanding is also important for testing and debugging. Programming style embellishes the readability of...
The reaction of fluid or gas flowing around an obstacle is a common engineering problem. Computer simulations are often used to measure and visualize the physical processes involved. In this report, we will discuss a parallel implementation of a simulation using the Smooth Particle Hydrodynamics (SPH) approach to fluid flow....
With sequential computing technology reaching its speed limits, parallel processing is emerging as the key to very-high-speed computation. However, developing a parallel program is by no means a simple task; neither is analyzing the performance of parallel programs.
C* is a high-level data-parallel language that hides explicit message passing and...
Hayes, in his Naive Physics Manifesto, identified two alternate ontologies for reasoning about liquids, an ontology based on the notion of a contained substance and one based on the notion of a molecular collection. Qualitative Process theory, proposed by Forbus, lends itself easily to encoding the contained substance ontology. It...
In this report, we describe an implementation of a prototype information resources management system for the synthesis and integration project of the forest response program using a 4GL application development system ACCELL. Our system is called Prototype Virtual Data Management System (PVDMS). ACCELL is a software package that combines a...

Loss of a limb can severely impact everyday way of life. Prosthetics provide a way to return functionality to the user and improve quality of life. However, most prosthetic systems currently available in the market lack sensory feedback making them comparatively more difficult to use resulting in prosthetic abandonment. Therefore,...
"What’s wrong with this AI?" Explainable AI (XAI) researchers are moving beyond explaining an AI’s actions, to helping users detect an AI’s failures. However this detection may not be enough—for actionability, we often need to pinpoint which part failed. We investigate how AAR/AI, a structured assessment process, supports users with...
Coral reefs form vast ecosystems in tropical oceans that are hotspots for biodiversity and are economically valuable. The ecological success of coral reefs is made possible by the symbiotic relationship between corals and dinoflagellate algae from the family Symbiodiniaceae. In this symbiosis, the algae are found within host gastrodermal cells...
The characterization of the seismic performance of structures relies on numerical simulations. However, estimates of seismic response are subject to various sources of uncertainty, including modeling uncertainty. This research estimated the response of two full-scale structural specimens composed of a moment resisting frame, elastic spines, and force-limiting connections (FLC), which...
One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...
The WNBA is a league that has been characterized by struggle ever since its inception in 1996. The biggest reason for nearly all of its problems lies with one source: money. The WNBA simply does not have enough money to make it a functionable professional sports league. As a result...
Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
Cell division, arguably the most important event during the life cycle of the eukaryotic cell, is achieved through a complicated yet beautiful machinery. The mitotic spindle — a microtubule-based bipolar structure—is the cellular machinery responsible for the correct segregation of the genetic material, chromosomes. The protein-based nanomachines termed molecular motors...
Several new herbicides were compared with those presently being used in Oregon to control weeds in snap beans, red beets and new plantings of strawberries. The results of these tests are summarized in tabular form.
In vivo spectral analysis of radish leaves sought effects on radish light harvesting apparatus (LH) of the herbicides: clomazone (FMC57020; [2-(2-chlorophenyl) methyl-4,4 dimethyl-3-isoxalidinone), diuron (DCMU; [3-(3,4-dichlorophenyl)-l,ldimethylurea)] and amitrol (H-1,2,4-triazole-3-amine). All herbicides used cause visual symptoms of chlorosis or damage chloroplast membranes and thus disrupt LH structure. The spectra were obtained...
Several triazine herbicides were evaluated during the fall of 1967 and the spring and summer of 1958 on a variety of crop and week species to determine their potential selective and soil sterilant value.
