Multi-Dimensional Classification Algorithm for Automatic Modulation Recognition
This thesis proposes an approach for modulation classification using existing features in a more efficient way. The Multi-Dimensional Classification Algorithm (MDCA) treats features extracted from signals of interest as elements with irrelevant identities, hence eliminating any dependence of the classifier on any particular feature. This design enables the use of any number of features, and the MDCA algorithm provides the capability to classify modulations in higher dimensions. The use of multiple features requires an equal number of data dimensions, and thus classification in as high a dimensional space as possible can improve final classification results. Finally, the MDCA algorithm uses a relatively small number of simple operations, which leads to a fast processing time. Simulation results for the MDCA algorithm demonstrate good potential. In particular, the MDCA consistently performed well (at SNR levels down to -10dB in some cases) and in identifying more modulation types.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Microstrip Patch Antenna Receiving Array Operating in the Ku Band
Microstrip patch antennas were first investigated from the idea that it would be highly advantageous to fabricate radiating elements (antennas) on the same dielectric substrate as RF circuitry and transmission lines. Other advantages were soon discovered to be its lightweight, low profile, conformability to shaped surfaces, and low manufacturing costs. Unfortunately, these same patches continually exhibit narrow bandwidths, wide beamwidths, and low antenna gain. This thesis will present the design and experimental results of a microstrip patch antenna receiving array operating in the Ku band. An antenna array will be designed in an attempt to improve its performance over a single patch. Most Ku band information signals are either wide band television images or narrow band data and voice channels. An attempt to improve the gain of the array by introducing parasitic patches on top of the array will also be presented in this thesis.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The Combined Effects of Freestream Turbulence, Pressure Gradients, and Surface Roughness on Turbine Aerodynamics
A significant amount of research has been aimed toward turbine blade surface roughness, freestream turbulence, and pressure gradients and their associated efficiency losses. Typically, roughness studies use artificially created surfaces that are easily characterized by statistical parameters such as average centerline roughness, Ra, which is, in turn, often correlated to the well-defined equivalent sandgrain roughness, ks. This research differs in that it uses scaled facsimiles of real turbine blade surfaces to characterize correlations between blade roughness, with the combined effects of freestream turbulence and pressure gradients, and skin friction coefficient (Cf). The models tested yielded Ra values ranging from 0.1 to 1.2 mm and were representative of eroded, fuel deposited, pitted, and thermal barrier coated (TBC) surfaces with spallation. For the eroded surfaces, the addition of roughness caused Cf increases up to 300% when compared to flat plate data. Addition of freestream turbulence caused increases up to 125%. The combined effects of roughness and turbulence yielded increases up to 380%. This is 55% larger than simply summing the two independent effects. Though other surfaces typically offered less dramatic results, it was concluded that the Cf increases due to combined effects were consistently higher than the corresponding sum of the parts. The results presented for the combined effects of roughness and pressure gradients were inconclusive due to errors in measurement. However, limited observations seem to corroborate the trends seen with zero pressure gradient.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Production at the Leading Edge of Technology
This book contains all contributions to the congress, in which both detailed scientific investigations and technological innovations in the process chains of machining and forming are discussed as well as comprehensive, far-sighted overall views on the planning and control of production processes. These approaches are supplemented by more interdisciplinary cross-sectional topics such as robotics, control engineering, automation, materials technology, additive manufacturing and human-centered production. It is particularly striking that the main approaches presented aim to improve efficiency in production using data-driven methods such as machine learning and artificial intelligence. However, the use of measurement results to improve simulations is also frequently addressed. The book proceedings show that transformations can only succeed through the realization of both detailed technical improvements in production technologies and optimized production organization.

The AFIT MEMS Interferometric Gyroscope
With the invention of Micro Electro-Mechanical Systems (MEMS) it has become possible to fabricate micro-inertial sensors. These new sensors have application in creating autonomous guided weapons systems. New technologies like Micro Unmanned Aerial Vehicles (UAVs), which cannot use conventional inertial sensors, rely on technologies like micro-inertial sensors to operate. Also, such sensors have the capability to reduce both power and space consumption on conventional aircraft. This technology is not yet mature, and current micro-inertial sensors do not have the accuracy required for highly precise navigation. To try to increase the accuracy of micro-inertial sensors, researchers are turning toward micro-optical gyroscopes. Creating a working micro-optical gyroscope is a difficult proposition as their small size precludes micro-optical gyroscopes from having large enough path lengths to sense useful rotation rates. Techniques need to be developed to create micro-optical gyroscopes with path lengths long enough to sense navigation grade rotation rates. This research proposes a new type of MEMS optical gyroscope. The device, called the AFIT MiG is an open loop Sagnac interferometer on a MEMS die. Mirrors are placed on the die to spiral light inward from the outside to the center of the die thereby increasing the optical pathlength of the device. When the AFIT MiG was simulated using flight profiles generated in MATLAB, the optical path length of the device was long enough to measure rotation rates, which were greater in strength than the noise inherent in the measurement.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Macroscopic Computational Model of Dielectric Barrier Discharge Plasma Actuators
Recent progress in the generation and sustainment of gas discharges at atmospheric pressure has energized research in the field of plasma-aerodynamics. Plasma actuators are promising devices that achieve flow control with no moving parts, do not alter the airfoil shape and place no parts in the flow. The operation of a plasma actuator is examined using a macroscopic (force and power addition) computational fluid dynamic model of a dielectric barrier discharge, DBD, in Fluent . A parametric approach is adopted to survey the range of requisite magnitudes of momentum and energy delivered to the flow field and to identify the effects of this localized momentum and energy addition on the flow characteristics. Simulations consider the initiation and control of flow over a flat plate in a low velocity fluid. The simulation velocity profiles are compared with the experimental observations of Corke (AIAA 2002-0350) as well as simulations of Font (AIAA 2004-3574), Boeuf and Pitchford (JAP 97 103307 2005), and Roy and Gaitonde (AIAA 2005-4631).This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Vibration Suppression of a Rotationally Periodic Structure Using an Adaptive-PPF Control Law
For a compressor disk, effective vibration suppression requires broadband control, and the elimination of inter-blade coupling forces. Previous researchers achieved this using an active-passive piezoelectric shunt network. Unfortunately, optimal tuning of the shunt requires prior knowledge of the coupling strength, which is not well defined. This thesis uses an adaptive parameter estimator to eliminate the inter-blade coupling forces. In addition, the passive shunt is replaced with an analogous positive position feedback method. The resulting control law was used on a simulated four and eight bladed system.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Conceptual Design Tool to Analyze Electrochemically-Powered Micro Air Vehicles
A multi-fidelity conceptual design tool was developed to assess electrochemically-powered micro air vehicles(MAVs). The tool utilizes four areas of contributing analyses (CAs): aerodynamics, propulsion, power management, and power sources to determine the endurance duration of a given mission. The low-fidelity aerodynamic CA consisted of drag polar calculations and the high-level CA used a vortex theory code called Athena Vortex Lattice (AVL). The propulsion CA employed QPROP and a MATLAB code that used experimental propeller data and motor constants to predict propeller-motor combination performance for the low- and high-fidelity tracks, respectively. The power management CA determined the percentage of required power the power sources needed to provide by a user-defined split or an optimization to maximize endurance duration for the two fidelity options. The power source CA used specific energy and specific power calculations for the low-fidelity track and polarization curves and Ragone plots for the high-fidelity track.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Classification of Radar Targets Using Invariant Features
Automatic target recognition (ATR) using radar commonly relies on modeling a target as a collection of point scattering centers. Features extracted from these scattering centers for input to a target classifier may be constructed that are invariant to translation and rotation, i.e., they are independent of the position and aspect angle of the target in the radar scene. Here an iterative approach for building effective scattering center models is developed, and the shape space of these models is investigated. Experimental results are obtained for three-dimensional scattering centers compressed to nineteen-dimensional feature sets, each consisting of the singular values of the matrix of scattering center locations augmented with the singular values of its second and third order monomial expansions. These feature sets are invariant to translation and rotation and permit the comparison of targets modeled by different numbers of scattering centers. A Mahalanobis distance metric is used that effectively identifies targets under "real world" conditions that include noise and obscuration. In particular, eight targets of military interest are sampled in tenth-degree aspect angle increments to extract scattering centers, and 36 subclasses that encompass ten degrees are specified for each target. Each subclass is compressed to a nineteen-dimensional singular value feature set, and because the spatial distribution of the 100 nineteen-dimensional points in each subclass is approximately Gaussian, a mean and a covariance matrix represent each subclass.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Verification and Validation Assessment of Rapid Availability Prototyping for Testing Operational Readiness
Through out the world, new techniques are developed to test and evaluate systems. The Department of Defense and the US Air Force conduct numerous studies into the reliability and maintainability of current and future weapons systems in an effort to understand the reliability, maintainability, and availability (RMA) performance of these systems. Furthermore, they must verify RMA characteristics of systems, which are still in the development phase. The Air Force Operational Test and Evaluation Center (AFOTEC) is responsible for testing new equipment to ensure their RMA characteristics meet specifications. Rapid Availability Prototyping for Testing Operational Readiness (RAPTOR) is the software tool developed by HQ AFOTEC to enhance existing analysis capabilities. RAPTOR is a modeling framework allowing quick creation of RMA models for many systems. DoD has made verification, validation, and accreditation (VVA) of these simulation models an official requirement.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Analysis of the Application of a Triggered Isomer Heat Exchanger as a Replacement for the Combustion Chamber in an Off-the-Shelf Turbojet
The objective of this research was to determine the feasibility of using a nuclear reaction heat source, such as the electromagnetically triggered decay of an isomer, in a solid-state heat exchanger to power an off-the-shelf gas turbine engine. Two primary performance measures examined were the total pressure decrement across the heat exchanger and the total temperature capability leaving the heat exchanger. The analysis included the use of acommercialsoftware package, ANSYS// 5.6.1, running on a 700 MHz Pentium III PC. This package includes the FLOTRAN computational fluid dynamics program, a finite element program based on unstructured meshes, with multiple discretization schemes, turbulence models, and advection options. Boundary conditions on velocity, pressure, temperature, heat flux, and heat generation are available and were used in this research. Three basic geometries of heat exchanger were explored in this research: Concentric annular tubes, radial trapezoidal fins, and a dual, concentric annulus of rectangular fins. These were selected due to the simplicity of geometry and potential ease of manufacture. In addition, because the flow through all of these geometries could be reasonably approximated by a series of two dimensional flow fields, run times were on the order of 1 day, a significant reduction from 3-D flow calculations. All three configurations produced sufficient heat transfer. Pressure ratios across the heat exchangers varied in the range from 94.597O to 97.5%. Turbine inlet temperatures varied from 986 K to 1150 K (1775 R to 2070 R). In the J-57 engine, these conditions will produce a static, sea-level thrust of approximately 37,000 N (8,300 lb.) to 47,000 N (10,600 lb.), compared to 46,000 N (10,300 lb.) for the conventional engine.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Handbook
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Liquid Crystal on Silicon Non-Mechanical Steering of a Laser Vibrometer System
This research examined the possibility of using a non-mechanical beam steering device to steer the beam of a coherent laser radar system. Non-mechanical beam steering devices offer many advantages in size, weight, power requirements, and steering speeds. Additionally, non-mechanical beam steering devices present the capabilities of splitting a single beam into multiple beams as well as beam forming and expanding. The coherent laser radar system used was a Laser Vibrometer System. The beam of the laser vibrometer was steered from 0 mrad to 3 mrad at 1 mrad increments using the liquid crystal on silicon (LCOS) device. The laser vibrometer was able to accurately measure a 2500 Hz vibration target on the steered vibrometry beam at all steered angles. A small LCOS noise signal was detected. The LCOS noise spectrum was determined to be consistent and predictable located at 60 Hz harmonics and was successfully subtracted from the signal. The LCOS device was used to split the vibrometry beam into 2 separate beams. The vibrometer was able to accurately measure two simultaneous independent target signals over the split beam.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Photogrammetry-Based Hybrid System for Dynamic Tracking and Measurement
Noncontact measurements of lightweight flexible aerospace structures present several challenges. Objects are usually mounted on a test stand because current noncontact measurement techniques require that the net motion of the object be zero. However, it is often desirable to take measurements of the object under operational conditions, and in the case of miniature aerial vehicles (MAVs) and deploying space structures, the test article will undergo significant translational motion. This thesis describes a hybrid noncontact measurement system which will enable measurement of structural kinematics of an object freely moving about a volume. By using a real-time videogrammetry system, a set of pan-tilt-zoom (PTZ) cameras is coordinated to track large-scale net motion and produce high speed, high quality images for photogrammetric surface reconstruction. The design of the system is presented in detail. A method of generating the calibration parameters for the PTZ cameras is presented and evaluated and is shown to produce good results. The results of camera synchronization tests and tracking accuracy evaluation are presented as well. Finally, a demonstration of the hybrid system is presented in which all four PTZ cameras track an MAV in flight.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
