Enhancement of pitting corrosion resistance for AA1050 processed by continuous closed die forging
Journal of Materials Research and Technology, 2020 The pitting corrosion of an aluminum alloy AA1050 after being processed by continuous closed die forging (CCDF) was evaluated by cyclic potentiodynamic polarization (CPP).

New Results On the Sum of Two Generalized Gaussian Random Variables [PDF]
, 2015 We propose in this paper a new method to compute the characteristic function (CF) of generalized Gaussian (GG) random variable in terms of the Fox H function. The CF of the sum of two independent GG random variables is then deduced. Based on this results,

Peak shrinking and interpolating for PAPR reduction in M-IFoF-based mobile fronthaul
Digital Communications and Networks, 2022 We apply a Peak Shrinking and Interpolating (PSI) scheme to improve the Peak-to-Average Power Ratio (PAPR) performance in Multiple Intermediate-Frequency-over-Fiber (M-IFoF) based mobile fronthaul.

Crowding effects in vehicular traffic [PDF]
, 2012 While the impact of crowding on the diffusive transport of molecules within a cell is widely studied in biology, it has thus far been neglected in traffic systems where bulk behavior is the main concern.
