The quantum cascade laser is a special kind of semiconductor laser, usually emitting in the mid- and long-wave infrared bands. Such a laser operates on laser transitions not between different electronic bands but on intersubband transitions of a semiconductor structure.  Their wide tuning range and fast response time allow for faster …

US Navy  plans to add as many as 32 attack submarines in just the next 15 years. Overall, the addition of attack submarines represents the largest overall platform increase within the Navy’s ambitious plan to grow the fleet to 355 ships. “Battle force inventory reaches 301 in 2020 and 355 in 2034,” …

As society become increasingly digital, financial services providers are looking to offer customers the same services to which they’re accustomed, but in a more efficient, secure, and cost effective way. Blockchain’s conceptual framework and underlying code is useful for a variety of financial processes because of the potential it has …

The fiber optic sensors also called as optical fiber sensors use optical fiber or sensing element.  These Sensors can measure a large variety of parameters, such as temperature, pressure, strain, refractive index, vibrations, displacements, bending, loading, and liquid level or concentration of chemical species.   Over the past decade, optical …

Auxiliary ships are vital to maintaining a strong and efficient naval fleet. They are designed to perform multiple roles to effectively support combatant ships in and out of battle, as well as complete other similar naval operations. Although auxiliaries assist other ships and do not execute primary combatant operations, they …

The world’s shipping industry is experiencing strong growth, which is expected to continue. Ships are getting larger and faster, sea-lanes are becoming more crowded, and crews are increasingly relying on electronic navigation systems to operate in this environment . The newly proposed concept of e-Navigation will improve safety, security, and …

In recent years, spread of terrorism has assumed an alarming proportion across the globe, because of the simplicity and variety of schemes by which these explosive-based weapons can be deployed causing enormous damage to public safety and environmental pollution. This has emphasized the need for rapid, sensitive and reliable detection …

The utility of Modern high frequency Radars have become degraded due to  innovation in stealth that resulted include unusual shapes that deflect radar waves—like the US B-2 bomber’s “flying wing” design (above)—as well as carbon-based materials and novel paints.  China and Russia have since gotten stealth aircraft of their own, …
