in order to support combat intelligence operations and troop engagement decisions; to enhance the decision-making prowess of commanders in the battlefield; and to develop robust physics-based, high-performance computing models and software for concept evaluation, design, and analysis (usually in support of computational science efforts in other ARL directorates)

This language technology group has focused on developing evaluation criteria and test conditions under which commercial technology offerings can be and are being evaluated in an environment that allows identification of the best candidates for Army deployment. Machine translation evaluation is critical to identifying which machine translation engines are good enough for which foreign languages to go on which systems and platforms to support which users performing which tasks.

This acoustical work is of great value to the Army because transmission loss resulting from propagation through the atmosphere is a key component in predicting acoustic detectability and acoustic signatures and therefore in determining operational acoustic sensor performance. Currently, BED is conducting research to develop and evaluate acoustic propagation models that incorporate the environmental effects of the atmosphere, turbulence, terrain, forests, urban structures, and land-water interfaces on acoustic signatures, and to develop remote sensing techniques using acoustic and seismic waves to provide information on conditions in the battlefield environment, including urban structures.

This essentially means determining good evaluation metrics and constructing very stressful scenarios and test cells in which candidate applications can be demonstrated in a common environment, with the best ones and remaining issues identified. Another area with tremendous implications for Army missions is ad hoc networks, especially wireless and sensors at the network nodes.

This would facilitate further progress in understanding the fundamentals of atmospheric signal propagation, particularly in battlefield environments when conditions are such that observations cannot be uniquely interpreted, and it could also facilitate collaborative studies with staff who work with computational fluid dynamics and high-resolution, mesoscale atmospheric models. RESEARCH ASSESSMENT Methodology The issue of validation and verification is one of continuing concern to the Board.

For example, several very successful deployments to Iraq of selected technologies have resulted from the Computer and Communication Sciences Division's approach to automated language translation technology. The Battlefield Environment Division has established its Army and national science niche in defining and predicting the characteristics of meteorological phenomena that are critically important to fixing the properties of the atmosphere and Earth on time and space scales relevant to rural and urban battlefield situations.
