Abstract:: Giardia and Cryptosporidium protozoans are resilient, zoonotic waterborne pathogens that can bypass water treatment and kill millions of people and animals annually. Giardia and Cryptosporidium cysts and oocysts, respectively, can spread through feces; poor sanitation and poverty can increase the risk for giardiasis and cryptosporidiosis diarrheal diseases. We are currently...

OGS : a lightweight object-oriented graphics system for instruction

Creator:: Zhu, Yanming
Abstract:: Existing graphics systems are too large for students to study in an introductory computer graphics course. We have implemented a lightweight, object-oriented graphics system called OGS for instruction. OGS is written in Java. It demonstrates how a graphics system is implemented from scratch and is intended to help students understand...

Description and comments on a matrix algebraic method for the determination of isomorphism in pairs of undirected graphs

Creator:: Fogg, Ka-Hung
Abstract:: This paper describes an investigation of a matrix algebraic method to determine isomorphism in pairs of undirected graphs. The method is described in some detail. The theoretical as well as the practical difficulties are given. It is shown that the method works for some cases. When the adjacency matrix of...

Decision analysis using the Hybrid Uncertainty Manager

Creator:: Yang, Charles J.
Abstract:: We present an extended mapping in the Hybrid Uncertainty Manager so that all the components of an influence diagram can be represented. This will allow us to perform decision analysis on a decision problem. Specifically, a representation for decision nodes, value node, and informational arcs will be given. With these...

Software channels : a distributed object-communication mechanism

Creator:: Worasucheep, Chukiat
Abstract:: In this paper, we describe a software mechanism, a software channel, that allows a group of distributed objects to communicate with each other automatically once they are connected to it. Software channels and predesigned distributed objects that are connected to them encapsulate the communication protocol and the network topology to...

Design and implementation of a simplified Kalman filter for an ocean circulation model

Creator:: Yao, Yunda
Abstract:: A Kalman filter was developed to recover information on short period variations of ocean circulation from the satellite altimeter signals for the North Pacific Ocean. The ocean circulation at each grid point is specified by three variables: sea level height h, zonal velocity u, and meridional velocity v. In our...

The structural active-object system approach to AGV system editor implementation

Creator:: Yan, Jimmy and Minoura, Toshimi
Abstract:: The Structural Active-Object System (SAOS) approach allows rapid development of various concurrent systems by structural and hierarchical object composition (SHOC). We implemented, as a SAOS program, a graphical editing and simulation program for automatic guided vehicle (AGV) systems, which carry around parts in automated factories. It is difficult to predict...

A message-passing system for the large-grain data-flow machine

Creator:: Thieret, Jeffrey and Lewis, Ted G.
Abstract:: The Large-Grain Data-Flow (LGDF) Machine is a tightly-coupled multi-processor consisting of several independent nodes, upon each of which may run one or more tasks. These tasks must be able to communicate and synchronize with each other. This document describes a message-passing system developed to meet these requirements. The message-passing system...

Weighted partial pattern matching

Creator:: Rudd, W. G. and Tekchandani, Rukmani
Abstract:: 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...

Quality of service for video stream over IP networks

Creator:: Liu, Xinying
Abstract:: 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...

A timing attack on software implementations of RSA

Creator:: Murari, Aneel
Abstract:: A timing attack on a cryptosystem allows the attacker to deduce the secret key information based on the timing differences with respect to different inputs given to an encryption or decryption algorithm. Cryptosystems can take variable amounts of time to process due to performance optimizations in software, branching or conditional...

An interactive workbench for sound experimentors

Creator:: Boone, Jeff
Abstract:: This project is an interactive environment which allows the user to explore various sound generation techniques. The three methods of sound generation used are (1) FM synthesis, (2) Additive synthesis, and (3) Karplus/Strong synthesis of plucked strings. The project also provides the capability to display the generated sound waveforms and...

SARNS : the SAOS road network simulator

Creator:: Rehfuss, Kurt T.
Abstract:: The SAOS Road Network Simulator (SARNS) is a graphical simulation program for transportation planning, implemented using the structural active-object system (SAOS) approach. A SAOS is an object-oriented concurrent system that consists of a collection of interacting structural active objects (SAOs), whose behaviors are determined by transition statements provided in their...

Design and implementation of a probabilistic reasoning workbench user interface

Creator:: Guo, Forngyuan
Abstract:: This paper describes the design and implementation of a graphical user interface for construction and evaluation of influence diagrams. Specifically, this paper documents the representation, display and mouse sensitivity of an influence diagram, and the selection facility subsystem. The interface is designed to communicate with the user by a mouse...

Principles of logic design

Creator:: Adrion, W. Richards, Herzog, James H., and Short, Robert A.
Abstract:: This study involves logic design and switching theory, in particular their practical application to the logic design and understanding of digital machines. Digital machines, of course, play an extremely important role in that large class of machines known as digital computers. But they also play an important role in many...
