Atmospheric correction of optical imagery from MODIS and Reanalysis atmospheric products

2010

article i nfo In this paper we analyze the differences obtained in the atmospheric correction of optical imagery covering bands located in the Visible and Near Infra-Red (VNIR), Short-Wave Infra-Red (SWIR) and Themal-Infrared (TIR) spectral regions when atmospheric profiles extracted from different sources are used. In particular, three sensors were used, Compact High Resolution Imaging Spectrometer (CHRIS), Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER) and Landsat5 Thematic Mapper (TM), whereas four atmospheric profiles sources were considered: i) local soundings launched near the sensor overpass time, ii) Moderate Resolution Radiometer (MODIS) atmospheric profiles…

Soil emissivity and reflectance spectra measurements

2009

We present an analysis of the laboratory reflectance and emissivity spectra of 11 soil samples collected on different field campaigns carried out over a diverse suite of test sites in Europe, North Africa, and South America from 2002 to 2008. Hemispherical reflectance spectra were measured from 2.0 to 14 microm with a Fourier transform infrared spectrometer, and x-ray diffraction analysis (XRD) was used to determine the mineralogical phases of the soil samples. Emissivity spectra were obtained from the hemispherical reflectance measurements using Kirchhoff's law and compared with in situ radiance measurements obtained with a CIMEL Electronique CE312-2 thermal radiometer and converted to emi…

Comparison between different sources of atmospheric profiles for land surface temperature retrieval from single channel thermal infrared data

2012

Abstract Different sources of atmospheric water vapor and temperature profiles were used with a radiative transfer model for retrieving land surface temperature (LST) from thermal infrared remote sensing data with the so-called single channel (SC) method. Retrieved LSTs were compared to concurrent ground measurements over homogeneous rice fields to assess the accuracy of the atmospheric profiles. These included radiosonde balloons launched at the test site near-concurrently to satellite overpasses, re-analysis profiles from the National Centers for Environmental Prediction (NCEP), and satellite sounder products from the Atmospheric Infrared Sounder (AIRS) and the Moderate Imaging Spectrorad…

Generation of Hardware/Software systems based on CAL dataflow description

2011

International audience; This paper presents a new development of rapid prototyping tools for system design based on data-flow specifications. In this context, the efficiency of tools for the automatic translation from the data-flow programs to C and/or HDL are assessed by means of two design cases. The paper also introduces the new concept of the automatic synthesis of interfaces. Such generic interfaces are implemented by using an embedded microprocessor, which can support a large variety of interfaces already available as native IP libraries in the case of FPGA. The two design cases described here have been developed, tested and validated on different implementation platforms. The results…

Diritto del lavoro

2017

Questa terza edizione dà conto dei mutamenti legislativi intervenuti nel biennio 2016-2017, che per la gran parte costituiscono il correttivo o l’implementazione, a livello di decretazione ministeriale, della riforma del diritto del lavoro attuata nel 2015 (c.d. Jobs Act). Interamente riscritta è la parte dedicata al pubblico impiego, interessato dalla c.d. riforma Madia. La nuova edizione di “Diritto del lavoro” di E. Ghera, A. Garilli, D. Garofalo e, si apre con un excursus sulle fonti e sui profili storici, passando poi all’analisi più dettagliata della disciplina del lavoro subordinato. L’autonomia privata e il rapporto di lavoro precedono la sezione dedicata alla formazione del contrat…

A Real time locating system for local fleet management

2006

Abstract Local locating systems are necessary where a big number of units are handled. In this case, we propose a management system for parking spaces for vehicles that are distributed among eight different-sized lots on a 1.8 million square meter premises. In order to quickly locate each particular vehicle in this area, a new real time location system (RTLS) has been successfully installed. The vehicle location system Moby-R automatically monitors every vehicle movement and tracks its current parked position. All the vehicles are given a data carrier which is attached to the inside rear-view mirror with a special hanger, precisely locating the vehicle within approximately five meters

Gestión de mano de obra en la empresa pública: el caso de RENFE

2008

Los cambios en las prácticas de gestión de mano de obra que se están aplicando en Renfe en las últimas décadas han conllevado una reducción drástica de la plantilla (flexibilidad en la salida), y una mayor disponibilidad laboral de los que han quedado (flexibilidad funcional). Dichos cambios guardan relación con la orientación privatizadora de la economía que impone un cuestionamiento del modelo de transporte ferroviario existente hasta fechas recientes. Asimismo, están condicionados por el hecho de ser una empresa pública (financiación presupuestaria, politización,...). El objetivo básico de las prácticas de gestión de mano de obra aplicadas en Renfe es la reducción de los costes laborales…

Mechanisms and predictors of chronic facial pain in lateral medullary infarction

2001

The purpose of this study was to identify clinical predictors and anatomical structures involved in patients with pain after dorsolateral medullary infarction. Eight out of 12 patients (67%) developed poststroke pain within 12 days to 24 months after infarction. The pain occurred in the ipsilateral face (6 patients) and/or the contralateral limbs and trunk (5 patients, 3 of whom also had facial pain). Ipsilateral facial pain was significantly correlated with lower medullary lesions, including those of the spinal trigeminal tract and/or nucleus, as documented by magnetic resonance imaging. The R2 blink reflex component was abnormal only in patients with facial pain. Likewise, pain and temper…

Assessment of Classifiers and Remote Sensing Features of Hyperspectral Imagery and Stereo-Photogrammetric Point Clouds for Recognition of Tree Specie…

2018

Recognition of tree species and geospatial information on tree species composition is essential for forest management. In this study, tree species recognition was examined using hyperspectral imagery from visible to near-infrared (VNIR) and short-wave infrared (SWIR) camera sensors in combination with a 3D photogrammetric canopy surface model based on RGB camera stereo-imagery. An arboretum with a diverse selection of 26 tree species from 14 genera was used as a test area. Aerial hyperspectral imagery and high spatial resolution photogrammetric color imagery were acquired from the test area using unmanned aerial vehicle (UAV) borne sensors. Hyperspectral imagery was processed to calibrated …
