UAV Unmanned Aerial Vehicle is very rapidly growing area of flying objects. Various tasks and possible areas of UAVs use are generating increasing demand for various types and designs. Thanks to simpler certification requirements UAV market could be used as a test field for various new technologies like wide use of modern electric systems. One of the area where electric systems could be impleme...

The electromagnetic momentum of a point electric dipole in a uniform magnetic field of strength B0 of infinite extent is equal to B0 × p/4, i.e., to half the electromagnetic momentum of a macroscopic dipole of electric moment p in the same field. This result is obtained using three different methods which provide a test of the internal consistency of electrodynamics with regard to the handling ...

Multiferroics with coexistent ferroelectric and magnetic orders can provide an interesting laboratory to test unprecedented magnetoelectric (ME) responses and their possible applications. One such example is the dynamical and/or resonant coupling between magnetic and electric dipoles in a solid. As examples of such dynamical ME effects, (i) the multiferroic domain wall dynamics and (ii) the ele...

The genetic basis of parallel innovation remains poorly understood due to the rarity of independent origins of the same complex trait among model organisms. We focus on two groups of teleost fishes that independently gained myogenic electric organs underlying electrical communication. Earlier work suggested that a voltage-gated sodium channel gene (Scn4aa), which arose by whole-genome duplicati...

In electric arc furnace steelmaking units, the essential parameters are reducing price, increasing production and decreasing environmental pollution. Electric arc furnaces are the largest users of electric energy in industry. The most important techniques that can be used to reduce the electric energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot ch...

roadmap is a strategic plan that describes the steps an organization needs to take to achieve stated outcomes and goals in different layers and these layers are closely related to each other. lower layer are more important in planning processes. acquisition layer is one of the most crucial layers in road mapping process. today there are some international organizations that do policy making and...

differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...

The present context of the electric industry, characterized by competitive markets, privatization, and regulatory of technical requirements forces the power utilities to optimize their asset management practices and develop the requisite decision plans techno-economically. Practically approaching, this paper devises a new support tool based on a multiattribute decision making (MADM) framework i...
