 | A major issue in computer security is limiting the affects a program can have on a computer. One way is to place the program into a sandbox, a limited environment. Many attempts have been made to create a sandbox that maintains the usability of a program and effectively limits the effects of the program. Sandboxes that limit the resources programs can access, have succeeded. To test the effectiveness of a ... |

| In the current work, we have implemented a numerical solver on the Graphic Processing Units (GPU) to solve the reactive Euler equations with detailed chemical kinetics. The solver incorporates high-order finite volume methods for solving the fluid dynamical equations and an implicit point solver for the chemical kinetics. Generally, the computing time is dominated by the time spent on solving the kinetics which can be benefitted from the computing power ... |

| An algorithm was developed using univariate statistics to reduce and analyze multivariate and multiple group data sets. The algorithm features the quantitative and selectivity figures of merit of receiver operating characteristics (ROC) curve methodology. This merging of two separate statistical analysis techniques resulted in the ability to address more than one variable in more than two experimental groups in a systematic fashion. The classic Fisher iris flower data set is ... |

| A liquid delivery system for nebulizers typically used in inductively coupled plasma spectrometry is implemented with active, closed-loop feedback to generate a constant, stable flow rate over extended periods of time. An electronic pressure control unit is coupled with a pressure vessel and flow meter in three separate configurations. The first configuration uses a computer to monitor the flow rate and adjust the pressure based on a PID algorithm. The ... |

| Richard Feynman first proposed the idea of quantum computers thirty years ago. Since then, efforts have been undertaken to realize large-scale, fault-tolerant quantum computers that can factor large numbers much more quickly than classical computers, which would have significant implications for computer security. While there is no universally agreed upon technology for experimentally realizing quantum computers, many researchers look to ion traps as a promising technology. This thesis focuses on ... |

Reducing the number of cache misses is an important component of runtime execution efficiency. We demonstrated runtime reductions of 3-5% in execution time, significant for embedded systems attempting to add new capability without ... |

| The development of honeypots as decoys designed to detect, investigate, and counterattack unauthorized use of information systems has produced an arms race between honeypots (computers designed solely to receive cyber attacks) and anti-honeypot technology. To test the current state of this race, we performed experiments in which we ran a small group of honeypots, using the low-interaction honeypot software Honeyd, on a network outside campus firewall protection.

| While there exist strong security concepts and mechanisms, implementation and enforcement of these security measures is a critical concern in the security domain. Normal users, unaware of the implications of their actions, often attempt to bypass or relax the security mechanisms in place, seeking instead increased performance or ease of use. Thus, the human in the loop becomes the weakest link. This shortcoming adds a level of uncertainty unacceptable in ... |

| This report reviews spherical harmonic expansions to compute wideband antenna patterns. Some antenna patterns, such as the far-field of a ship, require lots of computer time per each frequency. Consequently, computing such a pattern across a wide frequency band at each frequency is prohibitive. Spherical harmonics offer an alternative-compute the pattern over a coarse sampling across the frequency band, interpolate the spherical harmonics, and use these harmonics to recover the ... |

| Currently, private communications in public and government sectors rely on methods of cryptographic key distribution that will likely be rendered obsolete the moment a full-scale quantum computer is realized, or efficient classical methods of factoring are discovered. There are alternative methods for distributing secret key material in a "post-quantum" era. One example of a system capable of securely distributing cryptographic key material, known as Quantum Key Distribution (QKD), is secure ... |

| In the practice of information security, it is increasingly observed that the weakest link in the security chain is the human operator. A reason often cited for this observation is that the human factor is simpler and cheaper to manipulate than the complex technological protections of digital information systems. Current anecdotes where the human was targeted to undermine military information protection systems include the 2008 breach of USCENTCOM computer systems ... |

 | Person identification is the problem of identifying an individual that a computer system is seeing, hearing, etc. Typically this is accomplished using models of the individual. Over time, however, people change. Unless the models stored by the robot change with them, those models will became less and less reliable over time. This work explores automatic updating of person identification models in the domain of speaker recognition. By fusing together tracking ... |

| A constant weight codeword is a binary n-tuple with exactly r 1's. We show two circuits that generate constant weight codewords. The first is based on the combinatorial number system. Its input is an index to the codeword. That is, there are (n r) n-bit codewords with exactly r 1's. The index generates a unique codeword, and is a binary number between 0 and (n r) - 1. Such a ... |

| High performance and parallel computers have greatly increased the feasibility of performing large-scale analysis for engineering applications. However, it does take some effort to effectively use these high performance computing (HPC) resources. Appropriate parallel algorithms must be developed, tested, and optimized. The investment in time and resources required to accomplish this task is most often substantial. Therefore, developments should take place in a framework that is reasonably portable with minimal ... |
