Light sometimes appears to be "dragged" by the motion of the medium through which it is traveling. This phenomenon, referred ...

Deflagration-to-Detonation Transition (DDT) is a critical phenomenon relevant to the development of next-generation detonation-based propulsion ...

An international research team led by the Helmholtz-Zentrum Hereon has, for the first time, succeeded in visualizing and ...

A former “D” student from Norway, he made his mark at G.E.’s Research Lab in the U.S., in part by confirming a pivotal theory ...

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...

A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, convective flows in the mantle itself ...

The image above, provided by NASA, highlights how all three heat-transfer methods (conduction, convection, and radiation) work in the same environment. What is Conduction? Conduction transfers ...

“Scientists have long observed that the capability for a material to absorb electromagnetic radiation — a wave of energy in ...

Direct-drive wave energy converter (DDWEC) is more widely used due to its simple structure and high conversion efficiency. Different kinds of linear machines are used in DDWEC to improve the power ...

The transverse field sweeping system is capable of spreading electron deposited areas and reducing peak power density efficiently. In order to obtain lower peak power density further, the means of ...

Sound pressure level maps at 5 kHz, 10 kHz and 20 kHz for an incident unit amplitude plane wave incident on the abdomen. 3D maps of the SPL re 1 Pa are shown in (a)− (c) and (d)− (f) show a slice of ...
