Do Environment-related technologies strengthen the competitiveness of local systems?
De Noni I., Ganzaroli A., (Corresponding) Orsi L.
Topic:
Enviornmental data analysis and modelling
Environmental innovation is considered one of the key drivers of sustainable development and economic growth. However, we still know very little about the organizational factors underling the development of this category of innovations and their relative competitive effect. In this paper, we focus...Read more

A comparison between the past and future expected wind conditions in the European coastal environment of the Mediterranean Sea
(Corresponding) RUSU E.
Topic:
Enviornmental data analysis and modelling
In the last years, exploitation of the wind power has been constantly increasing together with the size of the turbines. Furthermore, by 2030 wind energy is expected to supply around 30% of EU’s power demand. Offshore wind represents a significant future opportunity, since resources are abundant...Read more

Currently, the priority in the EU countries is the subject of unemployment due to the economic and social situation in Greece and unemployment in Spain. Although unemployment in Poland has dropped, it is still quite high. The new economic models based on heterodox economics point to many new...Read more
Testing and validation of ENVI-met simulations based on in-situ micrometeorological measurements: the case of Syntagma square, Athens, Greece
Koletsis I., Tseliou A., Lykoudis S., (Corresponding) Pantavou K., Tsiros I.
Topic:
Enviornmental data analysis and modelling
The present paper focuses on the development of a methodology that simulates micrometeorological thermal conditions in an urban context based on weather station data. The micrometeorological conditions at Syntagma square, the central square of Athens, Greece were simulated by ENVI-met software in...Read more

The integration of three field survey datasets in Athens, Greece: transformation of five-point to seven-point thermal sensation scale
(Corresponding) Pantavou K., Lykoudis S., Delibasis K., Tseliou A., Koletsis I., Nikolopoulou M., Tsiros I.
Topic:
Enviornmental data analysis and modelling
The integration of the datasets from three different field surveys on thermal sensation conducted at eight different sites of the area of Athens, Greece was examined. All three surveys were carried out with similar methodologies so data integration can be considered meaningful. The surveys included...Read more

Species prioritization for recovery potential estimation. Case of study: Seasonally dry tropical forest at an inter Andean valley of Cauca River, South America
(Corresponding) Alvarado-Solano D., Otero J., Šarapatka B.
Topic:
Enviornmental data analysis and modelling
Seasonally dry tropical forest (SDTF) at the Colombian inter-Andean valley of Cauca River (IVCR) has been under constant transformation. Following the current SDTF’s global distribution, it has remained as small and sparse fragments embedded in an anthropogenic landscape. Information regarding the...Read more

Employing data-driven models in the optimization of chemical usage in water treatment plants
(Corresponding) Kandris K., Romas E., Tzimas A., Gavalakis E.
Topic:
Enviornmental data analysis and modelling
One of the most challenging tasks in potable water production is the cost-efficient and consistent operation of water treatment plants (WTPs) that treat raw water of variable quality and quantity. To increase process stability and optimize the usage of resources, two data-driven models simulated...Read more

A computationally efficient metamodeling-based approach for the automatic calibration of coupled hydrodynamic and water quality models
(Corresponding) Kandris K., Romas E., Tzimas A., Pechlivanidis I., Giardino C., Bresciani M., Schenk K., Bernert H.
Topic:
Enviornmental data analysis and modelling
Computational budget is a severe limitation on the automatic calibration of expensive hydrodynamic and water quality models. To tackle this limitation, the present work formulated a metamodeling-based approach for parameter estimation of such models and assessed the computational gains of this...Read more

An integrated methodology to estimate the contribution of environmental factors controlling the spatial variation of total dissolved solids. Application on Jiu River Basin (Romania)
(Corresponding) Morosanu G., Zaharia L., Ioana - Toroimac G.
Topic:
Enviornmental data analysis and modelling
The variation of the total dissolved solids (TDS) in river water is highly dependent on the natural and anthropogenic features of the TDS source areas, namely the river basins upstream of the measurement points. Despite the significant theoretical knowledge on the factors governing the TDS...Read more

Indoor and outdoor environment impact over the generic conditions for thermal bridge appearance
(Corresponding) Ivanov M., Mijorski S.
Topic:
Enviornmental data analysis and modelling
The presented study considers the numerical modelling of a thermal bridge distribution, based on conjugated heat transfer and Computational Fluid Dynamics (CFD) model of approximated external concrete wall. The thermal bridge distribution is cross-analyzed relative to the indoor and outdoor air...Read more
