Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 6,   Pages 796-807 doi: 10.1631/FITEE.1700023

Abstract: Two beamformers at the relay are studied for the approximate ergodic secrecy rate: (1) the generalizedlower-bound-maximizing (LBM) beamformer at the relay is discussed for maximizing the lower bound of the ergodicsecrecy rate.GRBF is the iteratively optimal beamformer, and that the performance of the LBM beamformer for the ergodicsecrecy rate gets close to that of the GRBF for the approximate secrecy rate.

Polypropylene microplastics alter the cadmium adsorption capacity on different soil solid fractions

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1,   Pages 3-3 doi: 10.1007/s11783-021-1437-z

Abstract:

Microplastics (MPs) are widely present in a variety of environmental media and have attracted more and more attention worldwide. However, the effect of MPs on the interaction between heavy metals and soil, especially in soil solid fraction level, is not well understood. In this study, batch experiments were performed to investigate the adsorption characteristics of Cd in bulk soil and three soil solid fractions (i.e. particulate organo matter (POM), organic-mineral compounds (OMC), and mineral) with or without polypropylene (PP) MPs.

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 2,   Pages 109-119 doi: 10.1007/s11465-012-0323-6

Abstract:

Working capacity refers to the velocity output and force output of a manipulator.It is usually be represented by output capacity space.The results show that the effect of the gravity is a translation of the capacity space.This paper gives a method for the output capacity express especially for heavy duty manipulators.The output capacity space can be helpful to the driving parameters selection.
