A Parallel Algorithm To Solve The Mathematical Problem "Double Coset Enumeration Of S₂₄ Over M₂₄", Elena Yavorska Harris Jan 2003

A Parallel Algorithm To Solve The Mathematical Problem "Double Coset Enumeration Of S₂₄ Over M₂₄", Elena Yavorska Harris

Theses Digitization Project

This thesis presents and evaluates a new parallel algorithm that computes all single cosets in the double coset M₂₄ P M₂₄, where P is a permutation on n points of a certain cycle structure, and M₂₄ is the Mathieu group related to a Steiner system S(5, 8, 24) as its automorphism group. The purpose of this work is not to replace the existing algorithms, but rather to explore a possibility to extend calculations of single cosets beyond the limits encountered when using currently available methods.

A Tail-Recursive Semantics For Stack Inspections, John Clements, Mathias Felleisen Jan 2003

A Tail-Recursive Semantics For Stack Inspections, John Clements, Mathias Felleisen

Computer Science and Software Engineering

Security folklore holds that a security mechanism based on stack inspection is incompatible with a global tail call optimization policy. An implementation of such a language may have to allocate memory for a source-code tail call, and a program that uses only tail calls (and no other memory-allocating construct) may nevertheless exhaust the available memory. In this paper, we prove this widely held belief wrong. We exhibit an abstract machine for a language with security stack inspection whose space consumption function is equivalent to that of the canonical tail call optimizing abstract machine. Our machine is surprisingly simple and suggests …


Accuracy In Spreadsheet Modelling Systems, Thomas A. Grossman Jr. Jan 2003

Accuracy In Spreadsheet Modelling Systems, Thomas A. Grossman Jr.

Business Analytics and Information Systems

Accuracy in spreadsheet modelling systems can be reduced due to difficulties with the inputs, the model itself, or the spreadsheet implementation of the model. When the "true" outputs from the system are unknowable, accuracy is evaluated subjectively. Less than perfect accuracy can be acceptable depending on the purpose of the model, problems with inputs, or resource constraints. Users build modelling systems iteratively, and choose to allocate limited resources to the inputs, the model, the spreadsheet implementation, and to employing the system for business analysis. When making these choices, users can suffer from expectation bias and diagnosis bias. Existing research results …


Creationism – A Viable Philosophy Of Mathematics, Jonathan Zderad Jan 2003

Creationism – A Viable Philosophy Of Mathematics, Jonathan Zderad

ACMS Journal 2004

In this paper, the author addresses two classical questions of the philosophy of mathematics: What, if any, of mathematics exists in the objective sense? How do humans know that our knowledge of mathematics is correct? He argues that the Christian doctrine of God as creator provides a basis for answering these questions. He also provides a critique of eight widely discussed philosophies of mathematics.

A Dynamic Real-Time Scheduling Algorithm For Reduced Energy Consumption In I/O Devices, Rohini Krishnapura, Steve Goddard Jan 2003

A Dynamic Real-Time Scheduling Algorithm For Reduced Energy Consumption In I/O Devices, Rohini Krishnapura, Steve Goddard

School of Computing: Technical Reports

In real-time systems, Dynamic Power Management (DPM) techniques have traditionally centered on the CPU with less focus given to I/O. However, I/O-based DPM techniques have been popularly researched in non-real-time systems. These techniques focus on switching I/O devices to low power states based on some policy. These methods, however, are not applicable to realtime environments because of the non-deterministic nature of the policies. Recently, scheduling techniques to reduce power consumption of I/O devices in real-time systems have emerged. In this paper, we propose an online task scheduling algorithm, Slack Utilization for Reduced Energy (SURE), which utilizes slack in periodic task …


On Modeling Protein Superfamilies With Low Primary Sequence Conservation, Stephen Scott, H. Ji, P. Wen, Dmitri E. Fomenko, Vadim N. Gladyshev Jan 2003

On Modeling Protein Superfamilies With Low Primary Sequence Conservation, Stephen Scott, H. Ji, P. Wen, Dmitri E. Fomenko, Vadim N. Gladyshev

School of Computing: Technical Reports

We present several algorithms for identifying thioredoxin (Trx)-fold proteins containing a conserved CxxC motif (two cysteines separated by two residues). The low conservation of primary sequence in this protein superfamily makes conventional methods difficult to use. Therefore, we use structural properties to build our classifiers. These structural properties include secondary structure patterns as well as various properties of the residues in the protein sequences. We use this information to model Trx-fold proteins via hidden Markov models, decision trees, and algorithms in the multipleinstance learning model. In 9-fold and 12-fold jack-knife tests, some of our models performed quite well, with high …


An Adaptive Qos Routing Protocol With Dispersity For Ad-Hoc Networks, Youngki Hwang, Pramod Varshney Jan 2003

An Adaptive Qos Routing Protocol With Dispersity For Ad-Hoc Networks, Youngki Hwang, Pramod Varshney

Electrical Engineering and Computer Science - All Scholarship

In this paper, we present the design and simulation of a bandwidth constrained multiple path on-demand routing protocol for ad-hoc networks to support end-to-end Quality of Service, which is known as the Adaptive Dispersity QoS Routing (ADQR) Protocol. We propose a route discovery algorithm to find multiple disjoint paths with longerlived connections, where each path also specifies associated network resource information. This provides an efficient approach for network resource reservation combined with data dispersion and for route maintenance. A longerlived path generally involves less route maintenance, resulting in an increase of bandwidth utilization. We propose a route maintenance algorithm to …


An Additive Schwarz Preconditioner For The Spectral Element Ocean Model Formulation Of The Shallow Water Equations, Craig C. Douglas, Gundolf Haase, Mohamed Iskandarani Jan 2003

An Additive Schwarz Preconditioner For The Spectral Element Ocean Model Formulation Of The Shallow Water Equations, Craig C. Douglas, Gundolf Haase, Mohamed Iskandarani

Computer Science Faculty Publications

We discretize the shallow water equations with an Adams-Bashford scheme combined with the Crank-Nicholson scheme for the time derivatives and spectral elements for the discretization in space. The resulting coupled system of equations will be reduced to a Schur complement system with a special structure of the Schur complement. This system can be solved with a preconditioned conjugate gradients, where the matrix-vector product is only implicitly given. We derive an overlapping block preconditioner based on additive Schwarz methods for preconditioning the reduced system.


Pid Stabilization Of A Position-Controlled Robot Manipulator Acting Independently Of In Collaboration With Human Arm, Anindo Roy, Kamran Iqbal Jan 2003

Pid Stabilization Of A Position-Controlled Robot Manipulator Acting Independently Of In Collaboration With Human Arm, Anindo Roy, Kamran Iqbal

Journal of the Arkansas Academy of Science

In this paper we develop framework for PID stabilization of a robot manipulator when using an object independently or in collaboration with a human arm. In both applications, the manipulator is equipped with a wrist sensor represented by an impedance. A second order manipulator transfer function along each coordinate direction is assumed. The aim of the paper is to design a PID controller when measurement of contact force, available via wrist sensor, is used to command the position controlled manipulator to a desired position and/or force profile. Necessary and sufficient conditions for stability of the closed loop system are developed …

Honeyd - A Os Fingerprinting Artifice, Craig Valli Jan 2003

Honeyd - A Os Fingerprinting Artifice, Craig Valli

Research outputs pre 2011

The research looks at the efficiency of the honeyd honeypot system to reliably deceive intruders. Honeypots are being used as frontline network intelligence and forensic analysis tools. A honeypots ability to reliably deceive intruders is a key factor in gathering reliable and forensically sound data. Honeyd's primary deceptive mechanism is the use of the NMAP fingerprint database to provide bogus OS fingerprints to would be intruders. Tests conducted by the author on honeyd's ability to provide bogus fingerprints sees 78% of 704 signatures invalidated under heavy probing. However, the tests left 152 viable signatures for producing hardened honeypot designs.
