Electric vehicle (EV) generators have characteristics of small volume and high power density, which leads to temperature rise. The rise will directly influence the service life reliability generator, so thermal analysis EV is necessary in machine design. This paper carries out a dual-axis-direction hybrid excitation generator (DHEG) used EVs. lumped parameter network (LPTN) method build three-d...

We propose a scheme of all-optical random number generator (RNG), which consists of an ultra-wide bandwidth (UWB) chaotic laser, an all-optical sampler and an all-optical comparator. Free from the electric-device bandwidth, it can generate 10Gbit/s random numbers in our simulation. The high-speed bit sequences can pass standard statistical tests for randomness after all-optical exclusive-or (XO...

The paper considers mechanisms for organizing free trade in the electricity market that are based on submitting bids of energy consumers and producers to the market operator. The authors discuss and compare possible strategies of generator behavior that lead to different equilibrium situations and correspond to Cournot model and the models of supply function equilibria, and a perfectly competit...

The paper is focused on a new passive greenhouse architecture, provided with cold water heat pumps, wind generator and solar panels. This greenhouse is independent of any energetic infrastructure (electric, gas, hot water). The sizing of each element and the automate control are critical in order to reduce the costs. A simplified mathematical model, able to assist the design and the automate co...

We measured specific heat directly by heating a sample uniformly between two electrodes by an electric generator. We minimized heat loss by styrofoam insulation. We measured temperature from multiple thermocouples at temperatures from 25 degrees C to 80 degrees C while heating the sample, and corrected for heat loss. We confirm method accuracy with a 2.5% agar-0.4% saline physical model and obt...
