    We propose a new relay selection artificial-noise (AN)-aided scheme to enhance the security of relay networks. We assume the presence of two multi-antenna eavesdroppers where one of them is closer to the legitimate transmitter (Alice) and the other one is closer to the ...

    We have investigated structural, magnetic and magnetocaloric properties of polycrystalline samples La0.5-x Eux Ca0.5 MnO3 (x=0 and 0.1). Rietveld refinement of the X-ray diffraction patterns show that our samples are single phase and crystallize in the orthorhombic stru...
