It is important to remember other angles rules, such as angles on a straight line add up to 180°, and to recognise angles in parallel lines. Make sure you are confident in applying Pythagoras’ theorem ...

Abstract: The instantaneous velocity of any moving object can be decomposed into two orthogonal components with reference to the observing radar, namely, radial velocity along the radar line of sight ...

Abstract: LCC-HVDC technology holds a significant proportion in China’s direct current transmission projects. When a fault occurs on the receiving-end AC system, leading to the commutation failure, ...

One of the current challenges in nanoscience is tailoring the phononic properties of a material. This has long been a rather elusive task because several phonons have wavelengths in the nanometer ...
