Electricity is cheaper than jet fuel on a per-unit-energy basis, which may result in operating cost savings. However, electric power generation is not actually emissions-free, since it requires considering generator fuels, transmission/grid losses, and life-cycle analysis of battery production and ...
In this paper, the conversion coefficient of battery life loss 𝑐𝑎ca is defined as the ratio of the replacement cost per unit capacity of electric vehicle power battery to the 1 kWh electricity cost. Table 2 lists the capacity and price of four pure electric vehicles power battery and ca...
The fluence of the prompt emission (i.e. the total time-integrated energy per unit area), lasting about 800s, was 0.013erg/cm2in the 75–1000 keV energy range23. This value is a lower limit estimate, due to the partial saturation and pile-up caused by the intense GRB photon flux. A...
In this regard, the WBG diode performance can be observed by the ideal specific on resistance. It is the resistance per unit area of this layer of material required to support the voltage. This resistance defines the per unit area for the resistance of the specific layer to support the volta...

The VSI can be used practically in both single- and three-phase applications. VSIs have good speed range, multiple motor controls from a single unit and a simple regulator design. In addition, there are some disadvantages of the VSI; e.g., the power factor decreases as the speed decreases...

As the control unit of the whole system, the rapid prototyping controller receives the signals from the motor controller, the engine controller, the battery simulation test system, the fuel consumption meter and the power analyzer through the CAN bus, and automatically generates the code according ...
“If they can eliminate the evaporation process, they can produce at a much lower price point, which would be great for the industry,” he said. Toronto-born Erceg, 41, has a master’s in business administration degree from Rice University in Houston and a law degree from South Texas Col...
Efficiencies of different propulsion technologies may be expressed either by CO2equivalent emissions per course unit (e.g., CO2/km), by energy units (MJ/km), or by percentages looking at the energy transformed to motion. Since petrol (in US: gas), diesel, LPG (propane + butane) as well...
