Energy losses in a magnetic nozzle radiofrequency plasma thruster are investigated to improve the efficiency, which calculated from particle energy fully kinetic simulations. The simulations calculate fluxes with vector resolution including lost dielectric wall, beam energy, and divergent addition collisional losses. As result, distributions of ratios input power obtained. simulation results sh...

Just as there are frictional losses associated with moving masses on a surface, what if there are frictional losses associated with moving information on a substrate? We propose to model these losses as proportional to “bit-meters,” i.e., the product of mass of information (i.e., its entropy) and the distance of information transport. For communication across a binary input AWGN channel, by obt...

The description of muon propagation through large depths of matter, based on a concept of the correction factor, is proposed. The results of Monte-Carlo calculations of this correction factor are presented. The parametrizations for continuous energy loss coefficients, valid in the broad interval of muon energies, and for the correction factor are given. The concrete calculations for pure water ...

In the framework of the dielectric theory, we present the electron energy loss probability distribution calculated for a fast probe near cylindrical surfaces using a non-local dielectric function. The small size of the drilled holes in experiments and electron trajectories close to the interface make necessary the introduction of dispersion effects when describing the energy loss spectra. We co...

This work deals with innovative energy efficient fluid power systems for mobile applications. The subjects taken up concern to what extent and how energy losses can be reduced in mobile working hydraulics systems. Various measures are available for increasing energy efficiency in these kinds of systems. Examples include: Flow controlled systems The pump controller is switched from a load sensin...

Transmission active power losses can influence the distribution of power flows in the transmission grid which consequently alter the generation dispatch and scheduling through the power system. This can especially affect the exploitation of large scale renewable energy sources (RES) since they are normally installed far away from load centres. RES technologies are expected to cover a large port...

In this paper we propose a distributed algorithm called S-REMiT for building an energy-efficient multicast tree in a wireless ad hoc network (WANET). S-REMiT employs a more realistic energy consumption model for wireless communication, which takes into account the energy losses not only due to radio propagation but also the energy losses in the transceiver electronics. This enables S-REMiT to a...
