(the ratio of the maximum retarding power to the maximum firing power), low-speed torque (essentially the shape of ‘torque vs. speed’ curve), weight, power-to-weight ratio (indicating packing space and the stress level), power density (i.e., specific power or the ratio of power to ...
This is especially true in China and the EU-27 plus the United Kingdom, where the sparsity of single-family homes with in-home parking has resulted in a higher ratio of EVs to charge points than in the United States. Put simply, the location of charge points will ...
However, I believe that in sizes corresponding to a thrust level of 100 tons and up, both systems could be made to have a thrust to weight ratio substantially in excess of one. In order to get a specific impulse greater than 2000 to 3000 seconds in space it is necessary to consider a...

Electric power steering has slowly made its way to the forefront of automotive engineering, with some of the greatest performance cars on sale (Porsche especially) transitioning their steering systems into the electronic age
Well-to-wheel greenhouse gas emissions may be reduced to 89–103 g CO2 km−1 compared to reference petrol (163 g km−1) and diesel cars (156 g km−1). Series hybrid cars with wheel motors have lower weight and 7–21% lower fuel consumption than those with central electric motors...
The FCs are seen as a power source small in size, light in weight, and easy to handle, and are thus best applicable in underwater vehicles. The interest to use logistic fuels motivated Office of Naval Research (ONR) to fund the development of SOFC hybrid systems as well. The UUV/AUV ...
ratio of the real prices for those two dates is 2.7. If instead of using the CPI, one calculates the “labor cost” using, say, the average wage of an unskilled worker (as suggested by Keynes), the comparison can be interpreted as how long it took the average worker to earn enough ...
the silicon IGBT is replaced by a GaN power HEMT or MOSFET, the GaN transistors are able to operate at a higher switching frequency and hence a lower switching energy loss, while simultaneously reducing the size of the reactive elements, such as inductors, and the heat sink size and weight....
