Harbor/Mooring Harbor Defense Concept
The long-term goal of this work is an integrated defense system that provides protection of Navy assets, while in port, from the threat posed by covert swimmers. The general concept is to hail, deter, and/or incapacitate the threat by directing a controlled level of low-frequency acoustic energy at the target location. At the system level, the concept requires combining elements of target detec...
متن کاملSoftware Engineering and Systems Engineering in the Department of Defense
October 1998 Twenty years ago, complex machines were controlled by hydraulic actuators or mechanical linkages using position switches and analog control circuitry. Today, much of the mechanical or hydraulic equipment and almost all analog circuitry has been replaced by servo motors, digital position encoders, and microprocessors. Complex machines still have a large mechanical component, but the...
متن کاملApplication of stem cells in tissue engineering for defense medicine.
The dynamic nature of modern warfare, including threats and injuries faced by soldiers, necessitates the development of countermeasures that address a wide variety of injuries. Tissue engineering has emerged as a field with the potential to provide contemporary solutions. In this review, discussions focus on the applications of stem cells in tissue engineering to address health risks frequently...
