It is a phenomenon that can cause damage to life and property and destroy the economic, social or cultural life of people. Over the past two decades, the impact of disasters …

Nanotechnology deals with the understanding, control and manufacture of matter in the nanoscale regime, usually between 1 nm to 100 nm, and exploiting them for a useful application. At this length scale unique properties and phenomena arise as a result of increased surface-to-volume ratio and dominance of quantum mechanical effects. …

Ai/ATR is a generic term to describe automated processing functions carried out on imaging sensor data in order to perform operations ranging from simple cuing of a human observer to complex, fully autonomous object acquisition and identification.   ATR can range from fully autonomous, such as, in a missile seeker …

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. Defencyclopedia defines a destroyer as “A modern destroyer is a 6000-12,000-ton warship, equipped with an array of long-range missiles, guns, and high power radars, and is designed …

The Joint Light Tactical Vehicle (JLTV)  is an Army-led, multiservice initiative to develop a family of future light tactical vehicles to replace many of the High Mobility, Multi-Wheeled Vehicle (HMMWV), which has been in service since 1985. The unarmored Humvee were found vulnerable to IEDs in Iraq and Afghanistan where hastily added …

The Hellfire missile is the primary 100-pound (45 kg) class air-to-ground precision weapon having multi-mission, multi-target precision-strike ability, and can be launched from multiple air, sea, and ground platforms, including the Predator drone.

Controlled Flight into Terrain (CFIT) is the #2 leading cause of General Aviation fatal accidents involving the loss of life. There have been over 9,000 deaths due to CFIT since the introduction of commercial jets.  Between 2000 and 2009 approximately 961 people died worldwide as a result of CFIT, the …

A metal foam is a cellular structure consisting of a solid metal (frequently aluminium) with gas-filled pores comprising a large portion of the volume. The pores can be sealed (closed-cell foam) or interconnected (open-cell foam). The defining characteristic of metal foams is a high porosity: typically only 5–25% of the …

Lidars (Light Detection and Ranging) are similar to radars in that they operate by sending light pulses to the targets and calculate distances by measuring the received time.  The  key advantages of  LIDAR is  its superior accuracy and its ability to see through masking items, such as leaves, trees, and …
