introduction environmental protection is one of the most priorities in land use planning. in this regard, place and location have the greatest role and its importance is increasing when the adverse effects of environmental neglect, can cause irreversible situation. selection a suitable location for the burial of solid waste can prevent the unfavourable ecological and socio – economic effects. l...

Cross-efficiency evaluation is an effective way of ranking decision making units (DMUs) in data envelopment analysis (DEA). Existing approaches for cross-efficiency evaluation are mainly focused on the calculation of cross-efficiency matrix, but pay little attention to the aggregation of the efficiencies in the cross-efficiency matrix. The most widely used approach is to aggregate the efficienc...

rangelands are among the natural resources which have a considerable effect on environment and man’s life. iranian rangelands mostly have poor condition and exhausted by intensive over grazing, should be utilized according to their ecological capability and land suitability. the main objective of this study is to evaluate ecological capability and land suitability of gheshlagh dam’s watershed a...

Abstract—During the last decade Panicum virgatum, known as Switchgrass, has been broadly studied because of its remarkable attributes as a substitute pasture and as a functional biofuel source. The objective of this investigation was to establish soil suitability for Switchgrass in the State of Mississippi. A linear weighted additive model was developed to forecast soil suitability. Multicriter...

In face recognition, one of the most important problems to tackle is a large amount of data and the redundancy of information contained in facial images. There are numerous approaches attempting to reduce this redundancy. One of them is information aggregation based on the results of classifiers built on selected facial areas being the most salient regions from the point of view of classificati...

a major concern of farmers is deterioration of the soil and water resources. soil management is the most direct way for mankind to interfere with natural processes that may either intensify or hinder soil degradation. fractal geometry has been widely used to describe heterogeneity in a wide range of natural processes, including physical systems of soil. in this study, the effects of different m...

In this paper, we propose a novel personalized aggregation approach to the multidimensional relevance aggregation. The approach is based on a mathematical aggregation operator relying on a fuzzy measure that allow to quantify the importance degree of each relevance dimension for every user as well as the interaction existing between the criteria. The evaluation of our approach is performed on t...

In this study, qualitative land suitability evaluation was made for research station of East Azarbaijan, for tomato, potato, onion and bean. The study was done using Simple Limitation Method (SLM), Limitation Method regarding Number and Intensity (LMNI) and Parametric Methods (PM) such as the square root and the Storie methods. The results from different methods indicated that the most importan...

For an accurate risk assessment of sites contaminated by trace elements (TE), measurements of bioavailability must be performed. This is routinely achieved using the standardized 0.01M CaCl2 method. However, the suitability of chemical extractions as proxies of bioavailability is questionable. We analyzed the correlations between chemically estimated TE bioavailability and TE actually accumulat...
