Backbending phenomena in light nuclei at A~60 mass region

Recent studies of the backbending phenomenon in medium light weight nuclei near A~60 expanded greatly our interest about how the single particle orbits are nonlinearly affected by the collective motion. As a consequence we have applied a modi…ed version of the exponential model with the inclusion of paring correlation to describe the energy spectra of the ground state bands and/or the backbending phenomenon in mass region at A~60. A firm conclusion is obtained concerning the successful validity of the proposed modified model in describing the backbending phenomenon in this region. Comparison with different theoretical descriptions is discussed.Comment: 4 pages, 1 figure

QED radiative corrections for elastic e(mu)p scattering in hadronic variables

A numerical analysis of QED radiative corrections for elastic e(mu)p cattering in hadronic variables at energies of the current experiment at JLab is performed. The explicit formulas from the review of Akhundov et al. resulting from the integration over the phase space of leptonic variables plus photon are used to obtain the values of the cross sections and the radiative correction factor for unpolarized lepton-proton scattering. Our numerical results agree with the corresponding results arising from the formulas of Afanasev et al.Comment: 4 Pages, 4 figure

Load analysis of ground-powering systems for electric vehicles

Dynamic conductive road charging involves the transfer of power into moving Electric Vehicles (EVs) using sliding contacts. The power transfer mechanism can be either installed from the top of the car using overhead conductors, conducting rails installed along the road-side or ground-level systems embedded in the road surface. The ground-level power system is the preferred option as it minimizes aerodynamic resistance compared to the other two as well as being designed for operation with vehicles of various sizes. In addition, existing technologies used in trams can be modified to provide ground-level EV charging systems. This paper investigates a ground-level system for EVs driving at high-speed on a motorway. It is based on the Tracked Electric Vehicle (TEV) project where EVs drive autonomously in a platoon with short inter-vehicle distance to reduce the overall air drag coefficient of the platoon. The paper investigates the optimum length and distance for the ground-level system. A Simulink model is developed for platoons of 10 EVs powered from a converter. It is shown that, for a platoon of 10 EVs driving with an inter-platoon distance of 50 m, a conducting-bar section100 m in length is the most efficient in terms of load variation and voltage stability
