OBJECTIVE This study examined operators' capacity to successfully reallocate highly autonomous in-flight missiles to time-sensitive targets while performing secondary tasks of varying complexity. BACKGROUND Regardless of the level of autonomy for unmanned systems, humans will be necessarily involved in the mission planning, higher level operation, and contingency interventions, otherwise know...

Dual-band Infrared-based passive Missile Warning Sensors (MWS) are under development at USAF Wright Laboratory and other DoD labs to provide aircraft with cost-effective robust detection and tracking of Infrared Surface-to-Air Missile threats out to their maximum launch ranges. Typically, such sensors are limited by the presence of heavy background clutter, solar glints, and sensor noise which ...

Background Data: Peripheral nerve injuries (PNIs) by either gunshot missiles or shrapnel from barrel bomb explosions are common during war.

We describe a simple single-particle tracking approach for monitoring the length of DNA molecules in tethered particle motion experiments. In this method, the trajectory of a submicroscopic bead tethered by a DNA molecule to a glass surface is determined by videomicroscopy coupled to image analysis. The amplitude of motion of the bead is measured by the standard deviation of the distribution of...

Although Blm and Top3α are known to form a minimal dissolvasome that can uniquely undo a double Holliday junction structure, the details of the mechanism remain unknown. It was originally suggested that Blm acts first to create a hemicatenane structure from branch migration of the junctions, followed by Top3α performing strand passage to decatenate the interlocking single strands. Recent eviden...

This paper assesses aircraft susceptibility from the first principles, with respect to the threat posed by passively guided infrared homing missiles; with an objective of gaining insight into the comprehensiveness of the relationship between aircraft susceptibility and aircraft infrared signature level. The conventional criterion of aircraft susceptibility assessment based on its lock-on envelo...

With increasing threat from different countries, India has to develop a strong defensive barrier against them. The emerging technology in war ammunition makes us one of the well armed countries in the world. One of the most used weapons is missiles, which were extensively developed under the guidance of Dr.APJ Abdul Kalam, the architect of IGMDP (Integrated Missile Development Program). Whateve...

As so-called “wooden rounds”, which are intended to sit stably in storage for extended periods and then function precisely as desired, at a moment’s notice, Air Force missiles would appear to be an ideal application for health monitoring. However, solid rocket motors that serve as the propulsion system for these missiles present a number of unique challenges for the development of integrated ve...

This study details a modular and general synthesis of a new class of molecules consisting of cruciform pi-systems. The key to synthesizing these molecules was an unprecedented double Staudinger cyclization. Once formed, these rigid compounds assemble into ordered monolayer films on metal and metal oxide surfaces to orient their conjugated, bis-phenyloxazole subunits upright. This surface orient...
