land use optimization using linear programing is a method in watershed management for access to production sustainability and decreasing of soil erosion. the sensitivity analysis of the model can with investigation of results influence form changes in input parameters, lead to decrease the uncertainty in decision-making of management programs. so in this research, linear programming model using...

Fuzzy Decision Tree (FDT) classifiers combine decision trees with approximate reasoning offered by fuzzy representation to deal with language and measurement uncertainties. When a FDT induction algorithm utilizes stopping criteria for early stopping of the tree's growth, threshold values of stopping criteria will control the number of nodes. Finding a proper threshold value for a stopping crite...

This study used quantifying factors affecting desertification based on the Iranian model of desertification potentialassessment (IMDPA) to assess the current status of desertification in Bordekhun region, Iran. Bordekhun region has anarea of 214.11 km2 and is located near the city of Daiyer in Boushehr province. First, a working unit map of the regionwas selected as the basic map for evaluation...

The main sources of methane emission are located in the undermined coal-bearing strata, which is not taken into account by requirements regulatory documents when determining category hazard coal mines. Gas from each source equally dependent on tons mined. relative gas changes during cleaning work and cannot be a criterion for assessing entire mine. volatility index per unit area underworked spa...

We show that for a given planar convex set K of positive area there exist three pairwise internally disjoint convex sets whose union is K such that they have equal area and equal perimeter. © 2009 Elsevier Inc. All rights reserved.

We give two new criteria by which pairs of permutations may be compared in defining the Bruhat order (of type A). One criterion uses totally nonnegative polynomials and the other uses Schur functions. The Bruhat order on Sn is often defined by comparing two permutations π = π(1) · · ·π(n) and σ = σ(1) · · ·σ(n) according to the following criterion: π ≤ σ if σ is obtainable from π by a sequence ...

Abstract Everyone studying EMU cites the theory of Optimum Currency Areas: whether a country like Sweden should join the currency union depends on such parameters as the extent of Swedish trade with other EU members and the correlation of Sweden’s income with that of other members. Few economists have focused on what we consider one of the most interesting aspects of this issue. Trade patterns ...

The study of multi-cue judgment investigates how decision makers integrate cues to predict the value of a criterion variable. We consider a multi-cue judgment task in which decision makers have prior knowledge of inter-cue relationships but are ignorant of how the cues correlate with the criterion. In this setting, a naive judgment strategy prescribes an equal weight for each cue. However, we f...

Varioussoftware for Geographical Information Systems (GISs) have been developed and used in many different engineering projects. In GIS applications, map coverage is important in terms of performing reliable and meaningful queries. Map projections can be conformal, equal-area and equidistant. The goal of an application plays an important role in choosing one of those projections. Choosing the e...
