Fields and Cyclic Codes for Error Detection
(20140114)This technical report discusses some of the aspects of error detection using finite fields. 
The Functional Hardware Design Language
(20091028)The Functional Hardware Design Language is an expandable language that is designed to make it easy to specify gatelevel. FHDL currently supports the specification of gates, highlevel functional blocks, state machines, ... 
Functions to Expand a PostgreSQL Database
(20091216)This is a set of functions to expand a PostgreSQL database via functions which analyze and manipulate graphs. The functions are internal, written in c. The import/export functions (using GraphML) are written in Java. 
The General Linear Group of GF(2)^3
(20120119)This technical report lists all 3x3 matrices over GF(2). Each matrix is listed along with its order and its inverse. At the end is a summary of the number of matrices belonging to each order. 
The General Linear Group of GF(2)^4
(20120119)This technical report lists all 4x4 matrices over GF(2). Each matrix is listed along with its order and its inverse. At the end is a summary of the number of matrices belonging to each order. 
Generator Pairs for all 4x4 GF(2) Representations of S4
(20130920)There are nine conjugacy classes of faithful representations of S4 in the general linear group of 4x4 matrices. This report gives generator matrices for one group in each class. These generator pairs allow each of the ... 
The GF(2) General Linear Group for Dimensions 2, 3, 4, and 5
(20090415)This report contains some data about the General Linear Groups of GF(2) for dimensions 2, 3, 4, and 5. These groups are groups of matrices over GF(2), the integers modulo 2. The General Linear Group of order is the set ... 
: GF2Matrices
(20090331)This is the software described in the technical report “The GF2Matrices Classes: A Programming Package for Mathematical Research.” Over the past few years I have been engaged in an intense study of GF(2) matrices, especially ... 
The GF2Matrices Classes: A Programming Package for Mathematical Research
(20090331)Over the past few years I have been engaged in an intense study of GF(2) matrices, especially of dimensions 2, 3, 4, and 5. The software I used for this study was mostly a bunch of adhoc subroutines scattered over numerous ... 
Giving the users a hand : towards touchless hand gestures for the desktop.
(, 20140905)Touchless, midair, gesturebased interactions have recently moved out of laboratories and Hollywood movies and into the hands of users. There is little difference in the interaction style and techniques used today from ... 
The HyperLinear Package
(20091113)The HyperLinear package is the core of the hyperlinear simulation technique described in Reference 1. Given the specification of a Boolean function, the package will detect all partial and total symmetries and return the ... 
HyperSim
(20091113)This software package implements the simulation algorithm described in the tech report “Using GF(2) matrices in Simulation and Logic Synthesis” found in this archive. (http://hdl.handle.net/2104/5263). This package is part ... 
Information storage capacity of genetic algorithm fitness maps.
(, 20110914)To accurately measure the amount of information a genetic algorithm can generate, we must first measure the amount of information one can store, using a fitness map. The amount of information generated, minus the storage ... 
The Inversion Algorithm for Digital Simulation
(20091105)The Inversion Algorithm is an eventdriven algorithm, whose performance rivals or exceeds that of Levelized Compiled code simulation, even at activity rates of 50% or more. The Inversion Algorithm has several unique ... 
The InversionAlgorithm Software
(20091113)The software in this package implements four versions of the Inversion algorithm. Four executable files are produced.These executables are used in much the same way as the FHDL package, but only AND, OR, NAND, NOR, NOT, ... 
The ISCAS85 Benchmarks in FHDL Format
(20091113)The three files that constitute this tech report are ISCAS85.fhdl.zip, ISCAS85.InputVectors.zip, and ISCAS85.VectorGenerators.zip. The first file contains the 10 ISCAS85 benchmarks in FHDL format, plus the smoketest circuit ... 
The ISCAS89 Benchmarks in FHDL Format
(20091113)The .zip file contains each of the ISCAS89 Benchmarks in FHDL format. Also included is a random vector generator file for each circuit. (For what it’s worth.) The generators are written in the DGL language. 
Java bytecode compilation for highperformance, platformindependent logical inference.
(20060511)Automated reasoning systems are powerful computer programs capable of solving complex problems. They are characterized as computationally intensive having high performance requirements. Very few reasoning systems have ... 
Matrix Representations of GF(p[superscript n]) over GF(p)
(20140131)We show that any nonsingular nxn matrix of order p[superscript n]1 over GF(p) is a generator of a matrix representation of GF(p[superscript n]). We also determine the number of matrix representations of GF(p[superscript ... 
Metamorphic programming
(20090415)Metamorphic programming is an effective tool for creating efficient and elegant solutions to many programming problems, at least once you get over the shock of seeing code that violates many of the accepted rules of good ...
