Partially-observed discrete-time risk-sensitive mean-field games
(IEEE, 2019)We consider in this paper a general class of discrete-time partially-observed mean-field games with Polish state, action, and measurement spaces and with risk-sensitive (exponential) cost functions which capture the ... -
Particle-flow reconstruction and global event description with the CMS detector
(IOP Publishing, 2017-10-06)The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic ... -
Performance analysis of relay-assisted NLOS ultraviolet communications over turbulence channels
(IEEE, 2017)Ultraviolet (UV) communication enables non-line-of-sight (NLOS) outdoor wireless connectivity and is particularly desirable for relaxing or eliminating pointing and tracking requirements of infrared links. In the current ... -
