AbstractEnvironmental pollution has become much more of a problem in recent years than it has been in the past. Pollution caused by garbage disposal, toxic substances sloping from different sources has attracted a great deal of attention and can be a great inconvenient for the environment and for the people. In the face of growing social expectations encompassing both standards of living and environmental concerns, the idea of sustainable development has become popular among governments, industr...

Abstract This paper applies a fuzzy method for the estimation of the daily electrical energy consumption of the fresh water hydrophore stations of a water distribution system. Based on the uncertainties of the water distribution system, the fuzzy logic was used to simulate a correlation between water and electrical energy quantities. Thus, the proposed method is proven as a useful tool for estimation of the daily electrical energy consumption considering the flow and the pressure growth of th...

Abstract Characterization of soil permeability is of great importance for several geotechnical analyses. In common practice, because of the difficulty in sampling of granular material, constant head permeability tests are usually employed on specimens having similar relative densities to those in the field. An alternative approach to permeability tests for granular soils is the prediction of permeability levels by means of empirical equations depending on several particle size distribution an...

Abstract Anaerobic digestion (AD) is a complex biological system which can be affected by several operational problems. Among them, biological foaming is one of the most difficult to deal with. It has many effects, such as causing gas pipe clogging and probe failures, and it can affect mixing devices, etc. Since the mechanisms involved in biological foaming development are not fully understood, it is not included in standard anaerobic digestion models. For this reason, a knowledge-based risk ...

Abstract Decision trees and rule-based systems including variants based on propositional and fuzzy logic have been the method of choice for knowledge representation in many applications of environmental decision support systems. Reasons are the ease of use, the capability of representing uncertainty, and the fast computation of results at runtime when using decision trees, rule-based systems, or other similar means for knowledge representation. Unfortunately there are drawbacks related with t...

Abstract An original Discrete Perfect Sets (DPS) algorithm was developed and applied to clustering of earthquake epicenters with M≥3.0 in California. The obtained clusters correspond well with the locations of the epicenters of strong earthquakes with M≥6.5. This fact allows considering them as earthquake-prone areas for the magnitude M≥6.5. We compared the obtained clusters with the areas recognized in 1976 using Earthquake-Prone Areas (EPA) method. The compariso...
