A novel-iterative simulation method for performance analysis of non-coherent FSK/ASK systems over Rice/Rayleigh channels using the wolfram language [PDF]
Serbian Journal of Electrical Engineering, 2016 In this paper, a new approach in solving and analysing the performances of the digital telecommunication non-coherent FSK/ASK system in the presence of noise is derived, by using a computer algebra system.

Performance of BPSK subcarrier intensity modulation free-space optical communications using a log-normal atmospheric turbulence model [PDF]
, 2010 In this paper, we present simulation results for the bit error rate (BER) performance and the fading penalty of a BPSK - subcarrier intensity modulation (BPSK-SIM) free-space optical (FSO) communication link in a log-normal atmospheric turbulence model ...

High-speed braking properties of Cu-based powder metallurgy brake pads
Fenmo yejin jishu, 2023 Friction coefficients of the Cu-based powder metallurgical brake pads decline due to the high temperature during the high-speed braking, which will directly affect the train braking effectiveness.

Reinforcement with Fading Memories [PDF]
SSRN Electronic Journal, 2016 We study the effect of imperfect memory on decision making in the context of a stochastic sequential action-reward problem. An agent chooses a sequence of actions, which generate discrete rewards at different rates. She is allowed to make new choices at rate β, whereas past rewards disappear from her memory at rate μ.

Fading Hawking radiation [PDF]
Astrophysics and Space Science, 2012 In this study, we explore a particular type Hawking radiation which ends with zero temperature and entropy. The appropriate black holes for this purpose are the linear dilaton black holes. In addition to the black hole choice, a recent formalism in which the Parikh-Wilczek's tunneling formalism amalgamated with quantum corrections to all orders in ...
