UBathy: a new approach for bathymetric inversion from video imagery [PDF]

open access: yes, 2019
A new approach to infer the bathymetry from coastal video monitoring systems is presented. The methodology uses principal component analysis of the Hilbert transform of video images to obtain the components of the wave propagation field and their ...

Fermi Detection of a Luminous gamma-ray Pulsar in a Globular Cluster [PDF]

open access: yes, 2011
We report the Fermi Large Area Telescope detection of gamma -ray (>100 mega-electron volts) pulsations from pulsar J1823--3021A in the globular cluster NGC 6624 with high significance (approx 7 sigma). Its gamma-ray luminosity L (sub 3) = (8:4 +/- 1:6) X

Reducing Cement Contents of Paving Blocks by Using Mineral Waste and by-Product Materials [PDF]

open access: yes, 2014
In the production of conventional paving blocks, it is usual to use a minimum of 210  kg/m3 of cement. However, when portland cement is produced, it impacts negatively on the environment due to carbon dioxide emissions. Therefore, this paper investigates

Determinants of airport cost flexibility in a context of economic recession [PDF]

open access: yes, 2013
The recent economic downturn led to a significant contraction in the global demand for air travel and cargo. In spite of that, airports' operating costs did not mirror the traffic trends and kept increasing during the same period, showing evident signs ...
