Different language versions of Wikipedia contain articles referencing the same place. However, an article in one language does not necessarily mean it is available in another language as well and linked to. This paper examines geotagged articles describing places in Honduras in both the Spanish and the English language versions. It demonstrates that a method based on simple features can reliabl...

We present promising results for real-time vehicle visual detection, obtained with adaBoost using new original “keypoints presence features”. These weak-classifiers produce a boolean response based on presence or absence in the tested image of a “keypoint” (~ a SURF interest point) with a descriptor sufficiently similar (i.e. within a given distance) to a reference descriptor characterizing the...

We present a consistent string theory model which reproduces the Standard Model, consisting of aD3-brane at a simple orbifold singularity. We study some simple features of the phenomenology of the model. We find that the scale of stringy physics must be in the multi-TeV range. There are natural hierarchies in the fermion spectrum and there are several possible experimental signatures of the mod...

Personal web usage can be defined as any voluntary act of employees using their company’s web access during office hours to surf non-work related websites for non-work purposes. Previous research suggested that personal web usage is a negative force with productivity losses, congested computer resources, security costs, and the potential risk of legal liability. However, using qualitative resea...

Introduction and background: Ballen silica, in the modification of α-quartz (‘ballen quartz’) or α-cristobalite, has been regarded as an impactcharacterstic microscopic feature for decades. The report of ballen silica in impact melt rocks from the Mien impact structure (Sweden; the impact melt rocks were formerly considered as rhyolites) was the first description of ballen silica in impactites ...

post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. sungun, nw iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. in this study, simple directional vario...
