Dropbox Forensics: Forensic Analysis of a Cloud Storage Service
English

2020 International Journal of Engineering Trends and Technoloy  
When misused as a tool of crimes, investigators can expect to find evidence and traces of criminal activity in both local system and cloud providers.  ...  This increased adoption of cloud storage had amplified the demand for cloud forensics, the cross-discipline between cloud computing and digital forensics.  ...  Since cloud is where the evidence resides, cloud is now the digital evidence which need to be preserved and acquired.  ...

Arguments against a dominantly hadronic origin of the VHE radiation from the supernova remnant RX J1713-3946

R. Plaga
2008 New Astronomy  
The flux of photons with energies above 1 TeV from the direction of the centre and a cloud in the western part of the nearby southern supernova remnant (SNR) RX J1713.7-3946 is calculated in the "hadronic  ...  While the size of this discrepancy might still seem acceptable in the face of various theoretical uncertainties, the result strongly suggests a strict spatial correlation of the cloud with an excess of  ...  Acknowledgements I thank Werner Hofmann, Alvaro de Rujula and an anonymous referee for critical remarks on a previous version of this paper, that helped to improve it significantly.  ...

The remnant of the SN is still embedded in the cloud, and cannot be observed due to extinction.  ...  We assume that the SN exploded in the molecular cloud p Oph in the 14th century B.C.; the cosmic rays were generated during the initial stage of the evolution of the remnant.  ... 

A Survey of Hydroxyl toward Supernova Remnants: Evidence for Extended 1720 MHz Maser Emission

J. W. Hewitt, F. Yusef‐Zadeh, M. Wardle
2008 Astrophysical Journal  
We present the results of GBT observations of all four ground-state hydroxyl (OH) transitions toward 15 supernova remnants (SNRs) which show OH(1720 MHz) maser emission.  ...  We infer that spatially extended, low level maser emission is a common phenomenon that traces the large-scale interaction in maser-emitting SNRs.  ...  A comparison with VLA detections in the literature allows us to identify which remnants show evidence for maser emission being resolved out by the interferometer.  ...

4.14. Molecular shell formation by supernova remnants in the Galactic center—what we learn from the case of W44

Masumichi Seta, Gisbert Winnewisser, Tetsuo Hasegawa, Glenn J. White, Tomoharu Oka
1998 Symposium - International astronomical union  
A considerable fraction of them may most probably be formed by an interaction between supernova remnants (SNRs) and molecular clouds.  ...  Studies of such cases in less confused areas are needed to clarify this picture. The SNR W44 is a good place for examining the SNR induced shell formation scenario.  ...  We established W44 as first unambiguously identified example interaction between the SNR and Giant molecular cloud based on following evidences of interaction: MASUMICHI SETA ET AL. 1) coincidence in position  ...

CORRELATION OF SUPERNOVA REMNANT MASERS AND GAMMA-RAY SOURCES

John W. Hewitt, Farhad Yusef-Zadeh, Mark Wardle
2009 Astrophysical Journal  
Supernova remnants interacting with molecular clouds are potentially exciting systems in which to detect evidence of cosmic ray acceleration.  ...  In many of the supernova remnants coincident with gamma-ray sources, the presence of OH(1720 MHz) masers is used to identify interaction with dense gas and to provide a kinematic distance to the system  ...  Of the 26 remnants for which an association with the coincident γ -ray source has not been ruled out, 7 are young remnants ( 1 kyr), 12 are SNRs with evidence of interaction with dense clouds, and 7 are  ...
