Digital Fingerprinting Of Field Programmable Gate Arrays, James W. Crouch
Digital Fingerprinting Of Field Programmable Gate Arrays, James W. Crouch
Theses and Dissertations
Commercial off-the-shelf (COTS) component usage is becoming more prevalent in military applications due to current Department of Defense (DoD) policies. The easy accessibility of COTS will give reverse engineers a higher probability of successfully tampering, coping, or reverse engineering circuits that contain critical capabilities. To prevent this and verify the trustworthiness of hardware, circuit identification tags or serials numbers can be used. However, these values can be easily obtained and forged. To protect critical DoD technologies from possible exploitation, there is an urgent need for a reliable method to confirm a circuit’s identity using a set of unique unforgettable metrics. …
Signal Processing Design Of Low Probability Of Intercept Waveforms, Nathaniel C. Liefer
Signal Processing Design Of Low Probability Of Intercept Waveforms, Nathaniel C. Liefer
Theses and Dissertations
This thesis investigates a modification to Differential Phase Shift Keyed (DPSK) modulation to create a Low Probability of Interception/Exploitation (LPI/LPE) communications signal. A pseudorandom timing offset is applied to each symbol in the communications stream to intentionally create intersymbol interference (ISI) that hinders accurate symbol estimation and bit sequence recovery by a non-cooperative receiver. Two cooperative receiver strategies are proposed to mitigate the ISI due to symbol timing offset: a modified minimum Mean Square Error (MMSE) equalization algorithm and a multiplexed bank of equalizer filters determined by an adaptive Least Mean Square (LMS) algorithm. Both cooperative receivers require some knowledge …

Hybrid Micro-Electro-Mechanical Tunable Filter, Edward M. Ochoa
Hybrid Micro-Electro-Mechanical Tunable Filter, Edward M. Ochoa
Theses and Dissertations
While advantages such as good thermal stability and processing-chemical compatibilities exist for common monolithic-integrated micro-electro-mechanically tunable filters (MEM-TF) and MEM-tunable vertical cavity surface emitting lasers (MT-VCSEL), they often require full processing to determine device characteristics. Alternatively, the MEM actuators and the optical parts may be fabricated separately, then subsequently bonded. This "hybrid approach" potentially increases design flexibility. Since hybrid techniques allow integration of heterogeneous material systems, "best of breed" compound optoelectronic devices may be customized to enable materials groups to be optimized for tasks they are best suited. Thus, as a first step toward a hybrid (AlxGa1- …

Triangulating Social Capital Measurement For Turnover Research: Applications To The U.S. Military, Frederic W. Lunas
Theses and Dissertations
In the United States, and around the world, social capital is becoming an intriguing new focus for slowing the declining sense of community and community trust. This strengthening focus on social capital in empirical study has great potential for an important role in U.S. public policy, as policy changes focused on increasing social capital may decrease turnover.
Yet, according to researchers, not enough sufficiently tested empirical measures of social capital exist. Combining several existing measures should provide a theoretically informed measurement of social capital for turnover research with application to the U.S. Military. Within this context, this thesis incorporated survey …

Strategic Planning To Conduct Joint Force Network Operations: A Content Analysis Of Netops Organizations Strategic Plans, Antonio J. Scurlock
Theses and Dissertations
Within the Joint Force Network Operations (NETOPS) environment, war fighters will treat net-centric adversaries and global information grid defense-in-depth situations as complex, adaptive enclaves that are the product of the dynamic interactions between connected entities and processes. Because of net centricity, no entity or process of the enclave can be considered in isolation; no singular engagement methodology will accurately capture the enclave’s complexity, and an alignment of Department of Defense Combatant Commanders, Services, and Agencies (CC/S/A) strategic planning is pivotal. To achieve and maintain information dominance, Joint Network Operations (NETOPS) organizations need to be strategically aligned. Strategic alignment allows organizations …
Use Of Tabu Search In A Solver To Map Complex Networks Onto Emulab Testbeds, Jason E. Macdonald
Use Of Tabu Search In A Solver To Map Complex Networks Onto Emulab Testbeds, Jason E. Macdonald
Theses and Dissertations
The University of Utah's solver for the testbed mapping problem uses a simulated annealing metaheuristic algorithm to map a researcher's experimental network topology onto available testbed resources. This research uses tabu search to find near-optimal physical topology solutions to user experiments consisting of scale-free complex networks. While simulated annealing arrives at solutions almost exclusively by chance, tabu search incorporates the use of memory and other techniques to guide the search towards good solutions. Both search algorithms are compared to determine whether tabu search can produce equal or higher quality solutions than simulated annealing in a shorter amount of time. It …
