 | The DoD is facing challenges to rapidly deploy operational capabilities in complex environments where bridging legacy and new technologies are key to success. The challenges arise as a result of diminishing budgets and the need for new capabilities to operate in war environments, including the global war on terrorism. To balance this imperative need with rapid response, we found that our developed Agile life-cycle paradigm was a viable solution to ... |

 | When asking a customer when they need something done you've most likely heard the reply, Yesterday! Why is this answer so common? Possibly it's because customers typically do not request products until they are needed. I liken this phenomenon to my lunchtime habits. I don't go looking for food until I'm saying out loud, I'm starving! Both are an exaggeration, but both cause the consumer to seek out those who ... |

 | High-performance computing (HPC) is in a state of transition. HPC users have traditionally relied upon two things to supply them with processing power: speed of the central processing units (CPUs) and the scalability of the system. There are problems with this approach. Physical limitations are curtailing clock speed increases in general-purpose CPUs, the von Neumann load-execute-store approach does not map well to every computational problem, and systems of thousands of ... |

 | Validation of safety-critical software requirements is a difficult and frequently misunderstood task. It answers the question of are we building the right product? and is essential to Software Engineering. However, validation is often confused with verification activities, or simply left as a final tick-in-the-box just prior to delivery. Current models for validation cannot satisfy the unique aspects of safety-critical software where building the right safety product is paramount. Software safety ... |

 | Operational-level planners in Maritime Operations Centers aim to assign naval forces in support of combatant commanders efficiently and effectively, but they lack a software-based planning tool to develop optimal ship employment schedules. They must assign ships to particular missions spread throughout numerous regions over a particular time horizon to meet the combatant commander's force requirements. Currently, this is a manual process. We present Navy Mission Planner (NMP), a decision aid ... |

 | Most intrusion detection systems rely on signature matching of known malware or anomaly discrimination by data mining historical network traffic. This renders defended systems vulnerable to new or polymorphic code and deceptive attacks that do not trigger anomaly alarms. A lightweight, self-aware intrusion detection system (IDS) is essential for the security of government and commercial networks, especially mobile, ad-hoc networks (MANETs) with relatively limited processing power. This research proposes a ... |
