In spite of the large amount of “hype” that accompanied virtual reality (VR) earlier this decade, the field has produced only a few examples of demonstrably useful systems. Systems must be fielded and validated to show that VR is useful for purposes other than academic research. This paper discusses two VR systems developed at the Naval Research Laboratory that have received validation by stati...

Reaction time of current and future naval warships is eroded since they are expected to operate in a large variety of situations with constantly increasing complexity. To cope with diverse air and surface threats, the warships, either operating in a single ship configuration or within a task group, will require their combat power resources to be efficiently managed. The coordination and tight i...

To increase combat effectiveness by networking the warfighter and to easily modify and expand its existing network architecture, the United States Navy requires shipboard computer systems that are network-centric and service-based and that support open architectures. However, they are limited by the radio frequency bandwidth that is available for shipboard communications. As a result, some netw...

Acoustic sensors have been used for battlefield applications since World War I. Acoustic sensors provide several advantages and are increasingly employed in the modern high-tech battlefield. The twenty-first century battlefield calls for cutting-edge technology for military superiority and deployment of state-of-the-art acoustic sensor systems that employ advanced acoustic signal processing. Th...

The Naval Ocean Systems Center (NOSC)is supporting DARPA's natural language research program in the area of test and evaluation. Preparations are being made for a task-oriented evaluation of text understanding systems, building off the natural language contractors' familiarity with texts taken from naval messages and NOSC's previous experience in carrying out system evaluations. The objective o...

Abstract In view of the fuzziness and uncertainty combat effectiveness evaluation index small bore naval gun, combined with AHP fuzzy method, method gun is studied. Firstly, main influencing factors are analyzed, system established. Then, based on theory, a model Finally, an example given to evaluate gun. This can effectively unify qualitative quantitative indexes in indexes, provide effective ...

If the balanced and sustainable urban development is the overall objective of the European Union in spacial planning, each member of the Union as well as those who are willing to join the Union must commit and conduct spacial strategies accordingly. However, such economic and probably social rationales are often ignored in the mist of politics and military. From geopolitics to national strategy...
