Environment both endowed and built are essential for tourism. However tourism and environment maintains a complex relationship, where in most cases environment is at the receiving end. Many tourism development activities have adverse environmental effects, mainly emanating from construction of general infrastructure and tourism facilities. These negative impacts of tourism can lead to the destr...

The effect of foam-like 3D graphene (3DG) in an electron transport material (ETM), viz. ZnO thin film, on the steady-state photoluminescence (PL), light-harvesting efficiency (LHE), photocurrent density (JSC), photovoltage (VOC), and charge parameters perovskite solar cells (PSCs) are systematically investigated. ETM is developed by spin coating a precursor solution containing varying amounts 3...

We provide and evalúate a fusión algorithm of remotely sensed images, i.e. the fusión of a panchromatic (PAN) image with a multi-spectral (MS) image using bilateral filtering, applied to images of three different sensors: SPOT 5, Landsat ETM+ and Quickbird. To assess the fusión process, we use six quality indexes, that confirm, along with visual analysis, good overall results for the three sens...

This study used a hydrodynamic and sediment transport process-based model to simulate maintenance dredging in macrotidal estuary: the Seine Estuary. sandy-muddy estuary allows access two major ports (Le Havre Rouen). The accounts for sand mud dynamics was previously validated turbidity morphodynamic coupling. Dredging is schematised as physical process responding simulated seabed evolutions. In...

پایش و مدیریت شوری، از مهم ترین موضوعات زیست محیطی به ویژه در مناطق خشک و نمیه خشک است. به منظور دستیابی به این هدف بهره گیری از ابزارهای نو مانند سنجش از دور اجتناب ناپذیر است. هدف از این مطالعه برآورد مولفه های شوری خاک (کلر، سولفات و هدایت الکتریکی) با استفاده از تبدیل طیفی تصاویر etm+ و aster به رادیانس و بازتابش سطحی در محدوده کویر ابرکوده در منطقه ای به وسعت 4/87 کیلومتر مربع است. بدین من...

a knowledge of soil surface conditions, especially desert crust, salt crust and desert varnish is useful for improving classification of remotely sensed data. desert crust can generate high levels of reflectance, similar to those areas with high salt concentration and non-saline soil. therefore, soil surface crusts might bias thematic remote sensing of soils. in this study, we evaluated the eff...
