Agriculture in the temperate zone of the Midwestern USA has removed most riparian buffer zones from the landscape, which impairs the soil functioning of the soil in these ecosystems. The objective of this study was to assess soil degradation in a non‐buffered riparian zone with an annual row crop (ARC) and in a longer established (more than 85 years) riparian cool season grass (CSG) buffer in central...
This paper introduces some new elements to measure the skewness of a probability distribution, suggesting that a given distribution can have both positive and negative skewness, depending on the centred sub‐interval of the support set being observed. A skewness function for positive reals is defined, from which a bivariate index of positive–negative skewness is obtained. Certain interesting properties...
In contingency situation, the ability to self-healing plays an important role on reducing the time to restore the energy supply. The increasing use of remote controlled equipment in power systems leads the development of more efficient techniques for automatic restoration of power supply, being particularly important in Smart Grid applications. This paper presents a methodology and system for automatic...
Coronary heart disease is a major cause of death in developed countries. There are some factors like cholesterol, high blood pressure, diabetes or obesity that increase the risk of having coronary heart disease. Early detection of the disease may have a better treatment response. Cardiac imaging methods require new processing analysis approaches. In this paper, new segmentation system has been studied...
The continuity of electric energy supply to consumers is a permanent objective of the power utilities, pursuing the development of technological solutions to improve the performance of restoring power in contingency conditions. The main purpose is to minimize the impact on the number of consumers affected and reduce the time required to restore the energy supply. In this way, the power utilities have...
This paper presents a heuristic method to solve the network reconfiguration problem in the presence of distributed generation (DG) in order to minimize energy losses and improve the performance indexes in distribution system. Topological reconfiguration corresponds to an important tool for planning and operation of electric power distribution systems. Considering the distribution operation planning,...
Topological reconfiguration is an important tool for the planning and operation of electric power distribution systems. Usually, the utilities can use multiple criteria regarding the observation of regulation policies and public awareness to drive the topological reconfiguration. Several researchers are looking for new optimization methods, as the complexity of this combinatorial issue is high in...

This work presents a new methodology for short term loading forecasting whereas the influence of climatic variables (temperature, relative humidity of the air and wind speed) in the consumption behavior of an electrical power distribution system. The proposed methodology involves creating a discrete probability model (Markov chain) from the classification of historical data in a Self-Organizing Map...
