 | This research investigates the potential for Plug-n-Play sensor integration for navigation and other applications. Specifically, the requirements of such a system are outlined and attempts are made to achieve them using two separate systems: one using Robot Operating System (ROS) as middleware and the other using more traditional software design patterns. The end result is not so much a deliverable in terms of software, but more of a feasibility analysis ... |

|
| The need for better detection of explosive devices has imposed a necessity for determining the dielectric response properties of energetic materials with respect to electromagnetic wave excitation. Among the range of different frequencies for electromagnetic excitation, the THz frequency range is of particular interest because of its nondestructive nature. The present study is based on significant progress in density functional theory (DFT), and associated software technology, which is sufficiently mature ... |

Wesley Bylsma; ARMY TANK AUTOMOTIVE RESEARCH DEVELOPMENT AND ENGINEERING CENTER WARREN MI
|
| This report documents GNU GCC options for interoperability between C/C++ and FORTRAN. Compiling legacy software on the Linux platform necessitated the usage of GNU compilers and changes to several intrinsic functions. Several miscellaneous related activities are also included. Experimentation was required to achieve success. Included are examples demonstrating particular usage of each. The functions addressed are TIME(), CTIME(), ETIME(), ITIME(), IDATE() (FORTRAN), getenv(), strncpy() (C), and vector (C++). |

|
| This dissertation develops a theory of the conceptual and procedural aspects involved with how reverse engineers make sense of executable programs. Software reverse engineering is a complex set of tasks which require a person to understand the structure and functionality of a program from its assembly language representation, typically without having access to the program's source code. This dissertation describes the reverse engineering process as a type of sensemaking, in ... |

|
| Aircraft course planning between two points in a clear, no threat environment is easy and straightforward. However, the addition of various threats can greatly increase the difficulty and complexity of course planning. Placing new waypoints along the edge of each threat, mostly skirting the dangerous environment, may not prove too difficult, but such courses are far from optimal. Given aircraft, environment, and time constraints it is likely a much more ... |

| The U.S. military has an increased need to rapidly identify nonconventional adversaries. Dismount detection systems are being developed to provide more information on and identify any potential threats. Current work in this area utilizes multispectral imagery to exploit the spectral properties of exposed skin and clothing. These methods are useful in the location and tracking of dismounts, but they do not directly discern a dismount's level of threat. Analyzing the ... |

| An important consideration in assessing the performance of model calibration software is that of run time. Minimizing the number of hydrologic model runs required during the calibration process is nearly always important, but particularly when the objective function landscape contains multiple local minima or hydrologic model run times are high. Minimizing the number of required model runs was one of the primary factors driving the research and development activities encapsulated ... |

| Fuzzing is an approach to software testing where the system being tested is bombarded with test cases generated by another program. The system is then monitored for any flaws exposed by the processing of this input. While the fundamental principles of fuzzing have not changed since the term was first coined, the complexity of the mechanisms used to drive the fuzzing process have undergone significant evolutionary advances.

|
| A ballistic coefficient (BC) can be determined by using two chronographs a measured distance away from each other and shooting a bullet so the velocity is measured by the two devices. Ballistic modeling software requires accurate measurement of ballistic coefficients to accurately predict downrange trajectories, wind drift, and retained energy. This article presents new measurements for 21 different bullets and shows that BCs can differ significantly from the claims of ... |

| Cyclic symmetry is a method in finite element analysis that allows for the simulation of an entire cyclically symmetrical structure based on a model of one repeating sector. The reduction of model size obtained using cyclic symmetry can significantly reduce computational cost. This technique was employed to optimize the three pronged tooling design used to assemble mortar fins to the mortar body. Using cyclic symmetry, only one-third of the model ... |

| A critical technology for operating groups of Uninhabited Aerial Vehicles (UAVs) is distributed guidance. Distributed guidance allows an operator to command several vehicles at the same time, reduces operator workload, and adds redundancy to the system. Some of the leading software candidates for achieving distributed guidance are known as Boid Guidance Algorithms (BGAs), which are agent-based techniques relying on the interactions of simple behaviors. Flight tests are crucial to the ... |

| Not long ago, around the mid-1980s, development of most new mechanical systems such as automobiles, consumer products, and military devices was performed manually on a drafting table or drawing board. Engineers used them to prepare layouts or 2-dimensional sketches of what they were designing. They then would take these layouts to a draftsman, who would create drawings of each part in the device. The drawings would subsequently be sent to ... |

| The ability of the software engineering community to achieve high levels of reuse from software frameworks has been tempered by the difficulty in understanding how to reuse them properly. When written correctly, a plugin can take advantage of the framework's code and architecture to provide a rich application with relatively few lines of code. Unfortunately, doing this correctly is difficult because frameworks frequently require plugin developers to be aware of ... |

| The Department of Defense seeks to develop body armor that is, among other things, lighter and more flexible. For example, the new armor based on shear thickening fluids (STF) is very flexible, but stiffens under the load of impacting projectiles in order to provide protection. Hence, the interaction of the armor with human tissue (e.g., muscle) becomes very important. However, there is not sufficient understanding in how tissue responds to ... |

| Security in computing systems to date has focused mostly on software. In this research, we explore the application and enforceability of well-defined security requirements in hardware designs. The principal threats to hardware systems demonstrated in the academic literature to date involve some type of subversion, often called a Hardware Trojan or malicious inclusion. Detecting these has proved very difficult. We demonstrate a method whereby the dynamic enforcement of a processor's ... |

| Locating sound sources has been of interest to the military, especially in locating sniper fire in an unconventional operational theater. Today, there are such systems to localize snipers, but they are bulky, heavy and do not employ networking, which can greatly improve the performance in terms of accuracy and reliability. Hence, there is a need to design a system that is small, compact, distributed, and reliable. In this project, an ... |

| Many Free Electron Lasers (FELs) utilize high current, high energy electron beams. Inevitably, a small fraction of the electrons in the beam will exist outside the core beam; these electrons are referred to as beam halo. The halo electrons will travel down an FEL's transport system with the core electrons; any portion of those halo electrons that intercept transport system components can generate radiation that is harmful to the operating ... |

| Pulse Detonation Engines (PDE) operate in a cyclic manner resulting in large changes in the combustion chamber pressure. The widely varying pressure ratio between the chamber and nozzle exit makes it difficult to efficiently produce thrust since a fixed area ratio exhaust nozzle would operate off design nearly the entire cycle. Therefore, a nozzle with the capability to create the necessary area ratio throughout the cycle is required to produce ... |
