The Centre for Next Generation Localisation (CNGL) is involved in building interactive adaptive systems which combine Information Retrieval (IR), Adaptive Hypermedia (AH) and adaptive web techniques and technologies. The complex functionality of these systems coupled with the variety of potential users means that the experiments necessary to evaluate such systems are difficult to plan, implemen...

In this work, a system for solving handwritten Arabic word recognition is proposed. The aim is focused on holistic word recognition, which is devoted to recognize averaged size lexicons by using a single classifier. Presently, we investigate the applicability of the Artificial Immune Recognition System (AIRS) to achieve the recognition task. For the feature generation step, ridgelet transform a...

[1] The spectrally resolved infrared radiances observed by AIRS provide a strict and insightful test for general circulation models (GCMs). We compare the clearand totalsky spectra simulated from the Geophysical Fluid Dynamics Laboratory GCM using a high resolution radiation code with the AIRS observations. After ensuring consistency in the sampling of the observed and simulated spectra and a p...

AbstructModels for synthesizing radiance measurements by the Atmospheric Infrared Sounder (AIRS) are described. Synthetics radiances have been generated for developing and testing data processing algorithms. The radiances are calculated from geophysical states derived from weather forecasts and climatology using the AIRS rapid transmission algorithms. The data contains horizontal variability at...

A computationally efficient method is developed to simulate the radiances in a scattering and absorbing atmosphere along an arbitrary path in the spectral region ranging from visible to far-infrared with a spectral resolution of 1 cm. For a given spectral region, the method is based on fitting radiances pre-calculated from the discrete ordinate radiative transfer (DISORT) at several wavenumbers...

Knowledge of the seasonal positioning Intertropical Discontinuity (ITD) is critical to understanding moist convective processes and associated rainfall over West Africa. This study constitutes a new analysis seasonality convection Africa, relative ITD, based on NASA's Atmospheric Infrared Sounder (AIRS) measurements from 2003 2018. Results show that AIRS resolves march including its inherent di...

Cet article contribue à une nouvelle lecture des sorties de la Grande Guerre et du poids anciens officiers dans les sociétés d’entre-deux-guerres. Dans continuité conflit, où jeunes hommes partageant compétences expériences se trouvent alliés ou opposés au-dessus tranchées, l’imaginaire chevaleresque permet préserver airs l’espoir d’une guerre moderne moins violente. Cette fiction s’inscrit dur...

[1] We use five years of data from the Atmospheric Infrared Sounder (AIRS) to develop a correlation between the frequency of Deep Convective Clouds (DCC) and the zonal mean tropical surface temperature. AIRS data show that the frequency of DCC in the tropical oceans is very temperature sensitive, increasing 45% per 1 K increase of the zonal mean surface temperature. The combination of the sensi...
