Estimating Infection Sources in Networks Using Partial Timestamps
, 2018 We study the problem of identifying infection sources in a network based on the network topology, and a subset of infection timestamps. In the case of a single infection source in a tree network, we derive the maximum likelihood estimator of the source ...

Analysis of the seismicity of Southeastern Sicily: a proposed tectonic interpretation
Annals of Geophysics, 2000 Southeastern Sicily is one of the Italian regions with high seismic risk and is characterised by the occurrence in the past of large destructive events (MS = 6.4-7.3) over a territory which is densely urbanised today.

Factors influencing parameters of laser ion sources
Laser and Particle Beams, 2007 Various applications demand various kinds of ions. Charge state, energy and the amount of laser produced ions depend, primary, on the wavelength, the energy, the pulse duration, and the focusing ability of the laser used. Angle of the target irradiation, angle of the ion extraction (recording), and mainly the focus setting may significantly influence ...

Seismic moment tensors and kinematic source parameters [PDF]
Geophysical Journal International, 1982 Summary. Parameters pertaining to the kinematics of a finite source are usually estimated by fitting specific fault models to the data. On the other hand, these parameters, including source location, are also contained in the moment tensors of higher degree.
