A hydrogel is a three-dimensional (3D) network of hydrophilic polymers that can swell in water and hold a large amount of water while maintaining the structure due to chemical or physical cross-linking of individual polymer chains. Hydrogels were first reported by Wichterle and Lím (1960). By definition, water must constitute …

In recent years, high power fiber and semiconductor laser technology has improved rapidly, with power density increasing by an order of magnitude or more. Much of this increase has been driven by demand for industrial cutting machines and high-bandwidth, long-range telecommunications. These same laser materials and devices can also be …

Game theory is a theoretical framework for conceiving social situations among competing players. According to game theory, the actions and choices of all the participants affect the outcome of each. In some respects, game theory is the science of strategy, or at least the optimal decision-making of independent and competing …

With the rapid development of the aerospace field, fiber-reinforced, resin-based composite materials have gradually replaced traditional metal materials due to their advantages of low density and high strength. An increasingly important innovation in the aerospace industry is the use of composite materials, and they have played a major role in …

Unmanned Aerial Vehicle (UAV) is defined as a powered, aerial vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload. Unmanned aerial vehicles (UAVs) are …

Indian Defense Ministry report had warned of the “grave threat” posed by the Chinese navy in the Indian Ocean. It suggested that China is widening its orbit of patrols beyond Chinese waters to jockey for control of highly sensitive sea lanes. In mid-2016, Indian naval officials said they were sighting Chinese …

Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. Collectively, they affect both the utility and the life-cycle costs of a product or system.   Although significant improvements have been made in increasing the reliability of basic components such …

Space capabilities have become central to many military operations, including missile warning, geolocation and navigation, target identification, and tracking of adversary activities.  US, Russia and China are world leaders in  militarization of space possessing extensive space infrastructure. The NASIC report said there number of foreign intelligence and imaging satellites “has tripled” to …
