Table 1.9shows the log2of the numbers 2, 4, 8 and 16. The log2of a number is the power to which you must raise 2 to obtain the number. So, to obtain the value 4 we must raise 2 to the power of 2 (i.e., 22) so log2of 4 is 2. Similarly, log2of 8 is 3 because 8 ...

Volume 4, Issue 2, 2017 Cover image:Quantum dots have introduced a new form of quantum engineering of materials properties based purely on size and dimensionality. In the last 30 years, quantum dots have emerged from an interesting theoretical idea to structures of real practical importance for ...
{b}_i = (l_x, l_y, \phi , \theta , \frac{q}{p}, t)\) on the same surface i using a projection matrix \(\mathrm {\mathbf {H}}_i\) to form a three dimensional residual vector: \(\mathbf {r}_i = \mathbf {m}_i - \mathrm {\mathbf {H}}_i \mathbf {b}_i\). ...

In the end, it is important for captive pandas preparing for release to form as little dependence on people as possible [58]. For example, the recently popular ‘panda costume’, in which giant panda keepers disguise themselves as pandas to get closer to captive individuals, seems to be ...
These models can also be combined to form increasingly complex models. Keras, being modular in nature, is incredibly expressive, flexible, and apt for innovative research. It is extremely easy to debug and explore. To learn more about the Keras, check out their official documentation or take ...
Manipulating light on the nanoscale has become a central challenge in metadevices, resonant surfaces, nanoscale optical sensors, and many more, and it is largely based on resonant light confinement in dispersive and lossy metals and dielectrics. Here, we
