Military looking to 4D printing to develop weapons that assemble themselves, last longer and adapt to specific conditions on command.

September 5, 2018 Defense & Military, Manufacturing, Weapons & Munitions Comments Off on Military looking to 4D printing to develop weapons that assemble themselves, last longer and adapt to specific conditions on command.

3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from printing small components to full drones on Naval vessels, printing replacement parts for fighter aircrafts to printing ammunitions, textiles, metals, human organs, clothing, buildings and even food. …

DARPA’s Biostastis aims to enhance soldier survivability after battlespace injuries by slowing their biological clock

September 2, 2018 Biotech & Synthetic Biology, Human & Soldier Systems Comments Off on DARPA’s Biostastis aims to enhance soldier survivability after battlespace injuries by slowing their biological clock

Biostasis is the ability of an organism to tolerate environmental changes without having to actively adapt to them. The word is also used as a synonym for cryostasis or cryonics. It is found in organisms that live in habitats that may encounter unfavourable living conditions (i.e. drought, freezing, a change …

DARPA’s Ground Truth program will create war game for testing the validity of social science models

August 29, 2018 AI & IT, Test & Measurement Comments Off on DARPA’s Ground Truth program will create war game for testing the validity of social science models

The social sciences can play important roles in assisting military planners and decision-makers who are trying to understand complex human social behaviors and systems, potentially facilitating a wide range of missions including humanitarian, stability, and counter-insurgency operations. Current social science approaches to studying behavior rely on a variety of …

DARPA MAA program aims to predict the terrorist threat of using weapons of mass terror (WMTs) through modeling and computational methods

August 16, 2018 AI & IT, Security & Threat Management, Weapons & Munitions Comments Off on DARPA MAA program aims to predict the terrorist threat of using weapons of mass terror (WMTs) through modeling and computational methods

DARPA launched the program Modeling Adversarial Activity (MAA) program with a goal to develop mathematical and computational techniques for modeling adversarial activity for the purpose of producing high-confidence indications and warnings of efforts to acquire, fabricate, proliferate, and/or deploy weapons of mass terror (WMTs). MAA assumes that an adversary’s …

DARPA’s TEAC program developed phased-array sonar technology for Unmanned Underwater Vehicles (UUW or UUV) to establish a network of distributed sonars for Anti Submarine Warfare

August 15, 2018 Electronics & EW, Navy & Maritime Comments Off on DARPA’s TEAC program developed phased-array sonar technology for Unmanned Underwater Vehicles (UUW or UUV) to establish a network of distributed sonars for Anti Submarine Warfare

Sonars are one of the primary systems for detection and tracking of submarines in Anti Submarine warfare. However modern nuclear and diesel electric submarines have become very stealthy and quiet. Another challenge is diesel-electric submarines operating in littoral waters which generate high false alarm rates (FAR). One of the ways …

DARPA’s TEE program developing skyrmion based high-density and energy-efficient magnetic information storage devices

August 12, 2018 AI & IT, Material Comments Off on DARPA’s TEE program developing skyrmion based high-density and energy-efficient magnetic information storage devices

In magnetic memories, information (for example, a collection of bits) is stored as clusters of spins, which are either an up or a down (or put differently, a one or a zero). These spin clusters, which form the basis of magnetic memories, become less stable when reduced in size. Magnetic …

New technologies to prevent Biofouling that costs shipping industries billions of dollars a year

August 9, 2018 Material, Navy & Maritime Comments Off on New technologies to prevent Biofouling that costs shipping industries billions of dollars a year

Biofouling is one of the main problems faced by every type of ship at the sea. Marine growth such as barnacles and mussels have been the reason for problems such as decreased ship efficiency, corrosion etc. Biofouling not only sticks to the external surface of the ships but also gets into …

DARPA’s MDP program aims for fast materials development for military platforms in extreme environments

August 7, 2018 Manufacturing, Material Comments Off on DARPA’s MDP program aims for fast materials development for military platforms in extreme environments

Military platforms—such as ships, aircraft and ground vehicles—rely on advanced materials to make them lighter, stronger and more resistant to stress, heat and other harsh environmental conditions. Currently, the process for developing new materials to field in platforms frequently takes more than a decade. This lengthy process often means that …

Polymer Photonics has wide applications for future small satellite systems, chemical and biological sensing and secure data storage

August 3, 2018 Photonics Comments Off on Polymer Photonics has wide applications for future small satellite systems, chemical and biological sensing and secure data storage

Silicon, which has been a leading material in microelectronic industry for decades, is an attracting platform for photonic Integrated Circuits ( PICs ) thanks to transparency in the most widely used telecom wavelength bands, high refractive index contrast with cladding materials (SiO2, polymers, air), well-known processing conditions and production scalability …

DARPA developing Very Low Frequency (VLF) systems to provide GPS like position and timing technologies in contested, underwater and underground Environments

July 23, 2018 Electronics & EW Comments Off on DARPA developing Very Low Frequency (VLF) systems to provide GPS like position and timing technologies in contested, underwater and underground Environments

The GPS system provides critical positioning capabilities to military, civil, and commercial users around the world. However, in many environments in which military operates (inside buildings, in urban canyons, under dense foliage, underwater, and underground) have limited or no GPS access. It can be significantly degraded or unavailable during solar …
