there are various views about deceision making for the model of growing crops in risky conditions such as: motad model, inome - variance, grade2 planning, inseparable linear planning, and limited extreme risk model, focus-loss model, and target- motad . in this study, target - motad model has been used as the optimum pattern of growing crops in arsanjan. the results have been compared with thos...

w hether the united kingdom (uk) should remain in the european :union: (eu) or not has been a fiercely debated issue both before and after the referendum in the uk on june 23, 2016. the main purpose of this paper is to evaluate the pros and cons of the uk leaving the eu. it is concluded that if the uk leaves the eu, the resulting economic shock would risk adverse effects on macroeconomic variab...

Let R and S be positive integers with R < S. We shall call the simultaneous Diophantine equations x −Ry = 1, z − Sy = 1 simultaneous Pell equations in R and S. Each such pair has the trivial solution (1, 0, 1) but some pairs have nontrivial solutions too. For example, if R = 11 and S = 56, then (199, 60, 449) is a solution. Using theorems due to Baker, Davenport, and Waldschmidt, it is possible...

This paper addresses real-time weapon classification by analysis of asynchronous acoustic data, collected from microphones on a sensor network. The weapon classification algorithm consists of two parts: (i) feature extraction from time-series data using Symbolic Dynamic Filtering (SDF), and (ii) pattern classification based on the extracted features using Language Measure (LM) and Support Vecto...

Numerous models are proposed to model international trade and promote it. Vanek, instead of designing a trade pattern based on the production, introduced a pattern based on the factor content of trade. In the present study, apart from the Heckscher-Ohlin-Vanek (HOV) theorem, we attempt to determine the factor content of Iran's trade without factor price equalization by using internal input-outp...

Gravity Equations are broadly used to estimate the impacts of trade impediments on trade flows. It is often stated that results are implausibly high. In theoretical foundations of the gravity equation, trade costs usually enter as "icebergmelting-costs". This paper offers an alternative approach to model trade costs. From a microeconomic point of view, trade costs should depend on trade input p...

We specify a system of equations that fully reflects the supply and demand sides of the market for agricultural open space at equilibrium. Although simple, the system is exceedingly flexible and allows for household and parcel heterogeneity. We derive an empirical model directly from the structural equations and contrast this using a simulated landscape with the econometric specification most o...
