The amount of kinetic energy that an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object. The following equation is used to represent the kinetic energy (KE) of an

The transmittance of glass depends on the type of glass and in particular on its minority constituents, such as Fe2O3. Figure 4.81 gives an example of the wavelength dependence of the transmittance, τλ, through ordinary window glass, defined as the fraction of incident light that is neither...
Current research in China focuses on the effect of height on zero-energy buildings. We suggest that fully utilizing the vertical façade and seeking for local renewable resources to aid achieve zero energy for middle and high-rise buildings is necessary. Although the rural areas of China have ...
We fabricate devices on the scale of tens of micrometres and use them to create a crossbar array architecture that we use to run an image recognition algorithm. We also assess the potential scalability of our devices for use in large-scale energy-efficient neuromorphic systems using simulations....
Potential energy is the energy that a body possesses because of its position. It can be thought of as stored energy. Gravitational potential energy is the energy that could be released if the body falls undergravity. The amount of potential energy that a body possesses depends on its height....
Corresponding to the strengthened mesoscale eddies (i.e., EKEme), the negative wind stress work that depends on the relative velocity between wind and sea surface current is also intensified. In addition, the negative pressure work divergence and the remaining three small positive terms also increa...
turbines. The power output of tidal current turbines highly depends on the prevailing current velocity regime (Fraenkel2002). Besides tidal current turbines, which are typically constructed with a horizontal or vertical axis, there are other devices that belong to tidal stream technology (see Sect.4...
(Holling,1973). Energy system resilience depends on the occurrence of severe weather incidents and includes the system’s capacity to predict, tolerate, restore, and respond to challenges (Gosh & De,2022; Panteli & Mancarella,2015). Various organizations and researchers define resilience with ...
Obviously, this is an energy transduction process that requires the sliding-state droplet movement. Throughout this sliding movement (Fig. 5g), the drop can be considered as a set of smaller droplets on the graphene network surface due to surface roughness. As droplets move by rolling (Fig. ...
