Artificial respirators use an electric source of energy to supply the various active components which control the airflow. A portable or autonomous respirator (emergency, war, ambulance, etc), needs a battery or an energy container to be supplied with grea ...
Micro-cogeneration in residential applications is one of the efficient ways of improving the energy conversion efficiency in buildings. Cogeneration systems will cover electrical and thermal needs while reducing both energy bills and CO2 emissions. Thanks ...
Diesel - electric traction is a well established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel powered locomotive is due to the reduced costs compared to the infrastructure cost o ...
The use of electrical equipment in rail and ship transportation is bound to consideration on mass and size, particularly because of conventional low frequency transformers. On this paper, an optimized multilevel converter with medium frequency transformer ...
During plasma excitation by high power Alfven waves at TCA, signals at harmonics of the generator frequency are observed in the plasma scrape-off layer. In this paper, experimental investigations of the sheath effect and the excitation efficiency and dispe ...
For pt.I see ibid., p.162-9. This paper describes a hierarchical simulation model for the analysis of long term power system's behavior. The effects of centralized (functions of the control center) and decentralized (protection apparatus, generator speed g ...
In the order to produce energy for the large amount of people still currently out of the national girds, different possibilities exist. For practical and economic reasons, the most popular one is the use of Diesel engines coupled with generator sets. Petro ...
A digital lock-in amplifier has been used to perform V-I time series acquisition when transport currents with amplitude above Ic are driven through Bi-2223 tapes. The current waveform is triangular, sinusoidal or with arbitrary shape, and is applied for se ...
This paper describes a 1 to 3.5 kWe hermetic scroll expander generator modified from a standard hermetic compressor, an organic Rankine cycle test facility built to test expanders up to 10 kWe and a set of experimental results using HFC 134a in the dry vap ...
