An analysis of available time series was performed to obtain descriptive, associative, and comparative statistics of the data set. Pearson correlation was used to estimate the...

The aim of this paper is to propose an improved algorithm for estimating the risk of bankruptcy of the Bulgarian insurance companies. The algorithm is developed based on the multi-layers neural arhitecture with input dates represented by values of indicators from the financial statements of Bulgarian insurances companies. The memory of the neural network will provide informations about the risk of bankruptcy. Development of the neural model (algorithm R2b2n- risk bankruptcy of Bulgarian insurance companies with ne...

Modelling of fine particulate matter (PM2.5) requires new approaches for the evaluation of population?s exposure and associated health effects in various urban microenvironments. Such decision support tools are assisting local authorities in adapting proper plans for minimizing the resulting ecological and epidemiological impacts. An environmental decision support system (EDSS) with web-based GIS capabilities was developed to allow for examination of PM2.5 fraction concentrations in Ploiesti city, Romania. The air...

Ploiesti is one of the major cities of Romania, which is confronting potential occurrence of high-concentration ground-level ozone events, having in view its industrial activity concentrated mainly on oil refining, oil extraction equipment and machinery, metalworking facilities, chemicals production, etc. Mobile sources (traffic and public transport system) have also a significant contribution to total air pollutants concentrations. This study aimed to analyze the concentrations of ground-level ozone (O3) and arom...
