Infrared cameras can detect the heat signatures of missile plumes in the mid-wave infrared waveband (3-5 microns) and are being developed for use – in conjunction with advanced tracking algorithms – in Missile Warning Systems (MWS). However, infrared imagery is also liable to contain appreciable levels of noise and significant levels of thermal clutter, which can make missile detection and trac...

We propose a novel, vision-based method for robot homing, the problem of computing a route so that a robot can return to its initial “home” position after the execution of an arbitrary “prior” path. The method assumes that the robot tracks visual features in panoramic views of the environment that it acquires as it moves. By exploiting only angular information regarding the tracked features, a ...

INTRODUCTION Missile embolization is regarded as a rare phenomenon in the world of penetrating trauma. While figures in the world of civilian trauma do not exist, there is reason to believe that missile emboli are frequent enough to warrant the attention of any medical decision maker who cares for trauma patients. The current literature offers a variety of cases, but consolidated commentaries o...

n overview of hydrocode analysis at the Applied Physics Laboratory is presented. Starting with an Independent Research and Development project that simulated a high-velocity impact test of a full missile, the Laboratory developed a damage-scoring method for hydrocode simulations of missile impacts that opened the possibilities for a number of other applications. Applications of hydrocode analys...
