Hybrid renewable energy systems (HRESs) are being incorporated and evaluated within seaports to realize efficiencies, reduce dependence on grid electricity, operating costs. The paper adopts a genetic algorithm (GA)-based optimization framework assess four management scenarios that embed wind turbines (WTs), photovoltaic (PV), an storage system (ESS), (EMS). were developed based different levels of integration, utilization, dependency optimize cost sustainability while reflecting the actual...
AbstractUrban air pollution can be quantified in terms of atmospheric turbidity if satellite images similar geometry acquired under clear atmosphere and conditions are radiometrically compared. This comparison conveniently carried out by evaluating 'the apparent contrast reduction' due to aerosols over land. However, this method is subject misclassification ground-reflectance temporal variations. paper proposes the complementary application temperature attenuation' procedure, which allows...
Natural resources' unexpected nature makes renewable energy sources' power supply irregular and inflexible; weather conditions are impossible to be predicted. Energy storage systems required balance this green ensure both off-grid autonomous infrastructures' stability reliability. Various technologies available, but the high initial capital cost uncertainty regarding future performance critical bottlenecks for possible investors. Batteries most common means, while hydrogen is one of least...
This study investigates the integration of soft sensors and deep learning in oil-refinery industry to improve monitoring efficiency predictive accuracy complex industrial processes, particularly de-ethanization debutanization. Soft sensor models were developed estimate critical variables such as C2 C5 contents liquefied petroleum gas (LPG) after distillation energy consumption columns. The refinery's LPG purification process relies on periodic sampling laboratory analysis maintain product...
This paper presents the potentiality of using NOAA-15 AVHRR observations for obtaining aerosol optical thickness (AOT) maps over metropolitan area Athens (Greece). The high correlation found between retrieved AOT values and PM/sub 10/ measurements, suggests that application differential textural analysis (DTA) algorithm on imagery whenever available cloud free could be used to provide daily maps, indicating air quality information greater area.
The pandemic has created opportunities which researchers, developers and planners should analyze, capitalize adapt. How much COVID-19 restrictions affected air quality in Mediterranean tourism destinations? Was there a rebound effect during post-lockdown period? Which was the behavioral change concerning urban mobility? Noteworthy changes pollutants' mean concentration on ground-level have been experienced. measured reviewed CO2, CO, NOx, CH4 under various climate conditions. 5-min traffic...
Satellite data of moderate spatial resolution (MODIS and MERIS) were used to retrieve the aerosol optical depth (AOD) over urban area Athens. MODIS products obtained at a horizontal 10 by km 2 centered Athens, while differential textural analysis (DTA) code was applied MERIS images relative‐to‐reference AOD with 260 m 290 m. The possibility exploiting full in retrieving grid few hundreds metres thereby investigated for first time. MERIS‐based AOD, centred 560 nm, showed strong positive...
The implementation of the Habitats Directive (Hab-Dir) in 1992 has been a major step towards more harmonized approach to nature conservation European Union (EU). Member states granted legal protection habitats and species listed by HabDir, designated areas high value as Natura 2000 sites. But designation is not enough: sites need be managed appropriately, impacts environmental pressures working on them require careful monitoring. Furthermore, member monitor status their entire territory,...
Abstract Ports are situated in susceptible, to climate change, areas. The continuous technological advances on the global market and growth of trade activities forcing ports find new ways be both competitive harmonize with sustainable development’s “legislation”. Specifically, this actually means practically evaluate all possible actions mean which can utilized order achieve their optimization greenification. main objective paper is investigate, analyse evaluate, through proposed...
Abstract This study investigates the potential of applying radial basis function (RBF) neural network architecture for classification multispectral very high spatial resolution satellite images into 13 classes various scales. For development RBF classifiers, innovative fuzzy means training algorithm is utilized, which based on a partition input space. The method requires only short amount time to select both structure and parameters classifier. new technique was applied area Lake Kerkini,...
The monitoring of aerosol concentrations becomes a high environmental priority particularly in urban areas. optical thickness the visible spectrum is surrogate for fine concentrations, especially under pollution conditions with low mixing height, and can be measured ground sampling density help satellite sensors. SIPHA code was developed such application on high-resolution images allows quantification over land, snow sea. compares multitemporal data sets evaluates radiometric alterations due...
