The Department of Defense (DOD) acquires goods and services from contractors, federal arsenals, and shipyards to support military operations. The acquisition is a broad term that applies to more than just the purchase of an item or service; the acquisition process encompasses the design, engineering, construction, testing, deployment, sustainment, and …

The performance of electronics degrades as temperature increases from the ambient temperature. The temperature of a device increases when the device is on since no system operates at 100% efficiency. Output power is not equal to the power fed to the device, and the difference between this is power loss. …

The past few decades have seen an escalation of power densities in electronic devices, and in particular in microprocessor chips. Together with the continuing trend of reduction in device dimensions this has led to dramatic increase in the thermal issues within electronic circuits. The electrons, in their passage through the …

Drones are increasingly making an impact on society and economy. Drones are used by the military for intelligence gathering, anti-aircraft target practice, and also for weapons platforms. They are also used for many civilian roles such as agricultural surveillance, mapping, tracking, search and rescue, traffic monitoring, firefighting, weather monitoring, engineering …

The maritime sector is on the verge of a digital disruption. As digital transformation of the maritime sector is gathering momentum that will have a major impact on operations and existing business models, simultaneously the threat cyber attacks is emerging. Further the  sector’s infrastructure will be exposed  to more and …

As computer processors have continued to shrink down to sizes where billions of transistors are on single chip, heat has increasingly become a bigger factor in their performance. If those CPUs did not get as hot in the first place, then much less energy would be needed to keep them …

JSTARS is a joint development project of the US Air Force and Army which provides a picture of the ground situation equivalent to that of the air situation provided by AWACS. Operating from a stand-off position often in excess of 200 km, it can detect, locate and classify tracks and …

Situational awareness of potential hostile targets and of friendly forces is considered to be a key component in obtaining and sustaining military superiority over adversaries.  Airborne Early warning and control (AWACS) aircraft provides a real-time picture of friendly, neutral, and hostile air and maritime activity under all kinds of weather …

Recent years have seen multiple new security challenges emerge in the maritime arena. Navies, coast guards and other maritime security agencies face a proliferation of security challenges. These include: illegal fishing of territorial waters; incursion of mineral exploitation across legal boundaries; maritime terrorism; narcotics smuggling; pollution as a result of …

The phonon is the physical particle representing mechanical vibration and is responsible for the transmission of everyday sound and heat. Understanding and controlling the phononic properties of materials provides opportunities to thermally insulate buildings, reduce environmental noise, transform waste heat into electricity and develop earthquake protection.   The concept of …
