This paper uses data envelopment analysis (DEA) to examine the technical, pure technical, and scale efficiencies of 12 branches of the agricultural bank in Guilan province, Iran over the period of 2012-2016. The first results indicated that scale inefficiency contributed more to overall technical inefficiency than pure technical inefficiency over the studied period. Results of return to scale r...

introduction: in this study, total factor productivity growth components in rough rice production are assisting by econometric approach and stochastic frontier function during 2005-2013 for several provinces (mazandaran province, guilan province, golestan province, fars province, khoozestan province). according to food and agriculture organization statics, iran is the 3rd importer and 20th expo...

In this paper, we present the cryptanalysis of a public key scheme based on a system of multivariate polynomial equations, the ”tractable rational map” cryptosystem. We show combinatorial weaknesses of the cryptosystem, and introduce a variant of the XL resolution algorithm, the Linear Method, which is able to leverage these weaknesses to invert in short time the trapdoor one-way function defin...

We present a new family of public-key encryption schemes which combine modest computational demands with provable security guarantees under only general assumptions. The schemes may be realized with any one-way trapdoor permutation, and provide a notion of security corresponding to semantic security under the condition that the message space has sufficient entropy. Furthermore, these schemes ca...

This study analyzed sea salt production and compared the technical efficiency level technology gap between traditional High-Density Polyethylene Geomembranes (HDPE GMB) in Phetchaburi province using a copula-based meta-stochastic frontier technique. A total sample size of 250 was chosen, comprising 195 farmers 55 HDPE GMBs farmers. Several copula families were used to analyze dependence structu...
