Android Malware Characterization using Metadata and Machine Learning Techniques
Android Malware has emerged as a consequence of the increasing popularity of
smartphones and tablets. While most previous work focuses on inherent
characteristics of Android apps to detect malware, this study analyses indirect
features and meta-data to identify patterns in malware applications. Our
experiments show that: (1) the permissions used by an application offer only
moderate performance results; (2) other features publicly available at Android
Markets are more relevant in detecting malware, such as the application
developer and certificate issuer, and (3) compact and efficient classifiers can
be constructed for the early detection of malware applications prior to code
inspection or sandboxing.Comment: 4 figures, 2 tables and 8 page
Planck 2013 Cosmology Results: a Review
This talk presents an overview of the cosmological results derived from the first 15.5 months of observations of the ESA’s Planck mission. These cosmological results are mainly based on the Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power spectra, although we also briefly discuss other aspects of the Planck data, as the statistical characterization of the reconstructed CMB maps, or the constraints on cosmological parameters using the number counts of galaxy clusters detected by means of the Sunyaev-Zeldovich effect in the Planck maps. All these results are described in detail in a series of papers released by ESA and the Planck collaboration in March 2013
The temporal evolution of the energy flux across scales in homogeneous turbulence
A temporal study of energy transfer across length scales is performed in 3D
numerical simulations of homogeneous shear flow and isotropic turbulence. The
average time taken by perturbations in the energy flux to travel between scales
is measured and shown to be additive. Our data suggests that the propagation of
disturbances in the energy flux is independent of the forcing and that it
defines a `velocity' that determines the energy flux itself. These results
support that the cascade is, on average, a scale-local process where energy is
continuously transmitted from one scale to the next in order of decreasing
size.Comment: Accepted for publication as a Letter in Physics of Fluid
