According to our point of view, global planetary evolution started from an originally homogeneous Earth. The differentiation of core and mantle started in upper layers. It is an important source of energy for all following processes.doi:10.1016/0264-3707(84)90007-3Stiller, Heinz...
The different distributions of water in planets change density structure, thermal structure (not shown), melting temperatures (not shown), and hence the extent of molten layers. Wherever the density profiles seem to flatten, we checked that all densities increase at all pressures. The density ...
Solar wind irradiation and high-velocity micrometeoroid bombardment dominate space weathering1,2for all airless bodies. However, the effects of these processes vary substantially, depending on the specific class of body. The solar wind is a plasma composed mainly of low-energy protons and electrons ...
Figure 8. Block diagrams of the IPMSM drive system based on current and direct torque control: (a) clock diagram of the IPMSM drive system based on current control in dq frame; (b) block diagram of the IPMSM drive system based on direct torque control in 𝛼𝛽αβ frame. In the se...
generally assumed to be uniform because their diagnostic geophysical phenomena are masked by the physical-properties of the upper layers.INTRODUCTIONIdealized, the inside of the earth can be de- scribed as being made up of layers, in a sequence of concentric shells as illustrated on the cover. ...
Use rugs and fabrics in office settings to infuse effortless layers of warmth into a cold professional environment. Additionally, textures offer a tactile and visual break from the technology that dominates modern workspaces, fostering a more relaxed atmosphere. But that’s not all. Beyond their aes...
A motor includes a rotor with interior permanent magnets and a stator with teeth wound by concentrated windings. Each permanent magnet is split along a plane oriented towards the stator, and an electr
Venus Express would be the first mission to make use from orbit of the newly-discovered near infrared transparency windows, so becoming the first to carry out systematic remote sensing observations of the Venusian atmosphere below and within, as well as above, the cloud layers. The payload for ...
