Dynamic Wavelength Scheduling by Multiobjectives in OBS Networks

Journal of Mathematics, 2022
The burst dropping ratio is witnessed in the contemporary literature as a considerable constraint of optical burst switching (OBS) networks that attained many researchers’ efforts in the recent past. Among the multiple practices endeavoring to reduce the

Fast Radio Bursts: Electromagnetic Counterparts to Extreme Mass-ratio Inspirals

The Astrophysical Journal Letters, 2023
Abstract Recent observations discovered that some repeating fast radio bursts (FRBs) show a large value and complex variations of Faraday rotation measures (RMs). The binary systems containing a supermassive black hole and a neutron star can be used to explain such RM variations.

Local seismicity induced unstable crack propagation in a coal and its effect on coal burst characteristics

Meitan xuebao, 2023
In this study, the acoustic emission evolution and stress drop processes of brittle coal specimens under quasi-static compression were investigated by experiments and numerical simulations, to reveal the pattern of mesoscopic crack evolution and its ...

An information-theoretic approach to the gravitational-wave burst detection problem [PDF]

, 2017
The observational era of gravitational-wave astronomy began in the Fall of 2015 with the detection of GW150914. One potential type of detectable gravitational wave is short-duration gravitational-wave bursts, whose waveforms can be difficult to predict ...

AGILE detection of delayed gamma-ray emission from GRB 080514B [PDF]

, 2008
GRB 080514B is the first gamma ray burst (GRB), since the time of EGRET, for which individual photons of energy above several tens of MeV have been detected with a pair-conversion tracker telescope.

Rock Burst Evaluation Using the CRITIC Algorithm-Based Cloud Model

Frontiers in Physics, 2021
Under high-stress conditions, rock burst disasters can significantly impact underground civil engineering construction. For underground metal mines, rock burst evaluations and prevention during mining have become major research topics, and the prediction

Correlations between various hardness ratios of gamma-ray bursts [PDF]

Astronomy & Astrophysics, 2001
We study correlations between various hardness ratios of gamma-ray bursts (GRBs) and investigate if there are any differences between the two classes of the objects in the distributions of the ratios. The results suggest that, statistically, the slope of the higher part of the spectrum of the long duration bursts has nothing to do with that of the ...
