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 …

The performance of digital receivers used in modern military radar, communication, and surveillance systems is often limited by the performance of the analog-to-digital converter (ADC) used to digitize the received signal. Ultrafast ADCs are critical in military applications such as military software-defined radio, radar, and electronic counter-warfare (ECW) that require …

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 …

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, …

Deep learning is a type of machine learning in which a model learns to perform classification tasks directly from images, text, or sound. Deep learning is usually implemented using a neural network architecture. Deep learning architectures such as deep neural networks, deep belief networks, recurrent neural networks and convolutional neural …

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. This class of micro- and nano-structured artificial media are predicted to be able to protect …

The term, structural electronics (SE), refers to a next-generation based electronics technology, which involves the printing of functional electronic circuitries, across irregular-shaped architectures. SE is expected to replace bulky load-bearing structures within a circuitry with smart electronic components that can conform to complex shapes for ensuring optimum space utilization. SE …
