Research ArticleOpen accessIn the abstractIdentifying the Factors Affecting the Participation of Agricultural Cooperatives' MembersBagher ArayeshProblem statement: 40-year history of agricultural production cooperatives in the country shows that this type of exploitation system has faced many ups and downs during this period. First, despite the help and support by the government, the cooperative sector has not been able to play a major role in the development of the country and its share has not exceeded … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 31 Dec 2011 · 8,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Influencing the Design of Electronic learning system in Agricultural ExtensionAmir Ahmadpour, Mehdi Mirdamadi, Jamal F. Hosseini, Mohamad ChizariProblem statement: Nowadays appropriate training and education are important. Still some organizations make the mistake of not training their employees adequately in the utilization of ICT or in the use of internet information systems, often due to the cost of providing training and the loss in productivity when employees are absent. But many organizations have adopted e-learning as a solution … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 25 Aug 2011 · 7,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractOR-Bridging Fault Identification and Diagnosis for Exclusive-OR Sum of Products Reed-Muller Canonical CircuitsV. Geetha, N. Devarajan, P. N. NeelakantanProblem statement: The faults in digital circuit can be classified broadly as single stuck-atfaults, multiple stuck-ay-faults, stuck-open faults, stuck-on faults, path delay faults, transient faults. Extensive research had been carried out in the field of testing of digital circuits to limit the number of input vectors. The cardinality of the test vectors proposed by many authors was quite high for … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractMoments of Order Statistics from Nonidentically Distributed Three Parameters Beta typeI and Erlang Truncated Exponential VariablesA. A. Jamjoom, Z. A. AL-SaiaryProblem statement: Moments of order statistics of independent non-identically distributed (INID) random variables is not an easy subject to deal with for continuous distributions. One is forced to use messy algebraic calculations (whether one uses permanents or not). This was the motivation behind this study. In this study the moments of order statistics arising from independent nonidentically distributed three parameters … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 31 Dec 2010 · 7,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost Analysis of a Two Dissimilar-Unit Cold Standby Redundant System Subject to Inspection and Random Change in UnitsG. S. Mokaddis, C. H. MattaProblem statement: This study deled with the cost analysis of a two dissimilar unit cold standby redundant system subject to inspection and random change in units. In this system each unit works in two different modes normal and total failure. Assuming that the failure, repair, post repair, interchange of units and inspection times are stochastically independent random variables each having … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteraction of Export Instability and Openness-Growth Nexus In East Asia and Pacific Countries (1990-2006)Zamanian Gholamreza, Pourshahabi Farshid, Shirazi AliProblem statement: Because of the importance of the relation between instability of economic variables and making decision for determinants, this is so considerable to find the interaction between instability and economic variables’ activity. Approach: One of the efficacious factors to have a positive trade balance is export that is a factor of GNP growth too. Moreover, openness is an important … …American Journal of Economics and Business Administration, Vol. 2, Issue 1 · 31 Mar 2010 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Influencing the Development of Entrepreneurial Education in Iran's Applied-Scientific Educational Centers for AgricultureBaharak. Azizi, Jamal F. Hosseini, Mahmood. Hosseini, Mehdi. MirdamadiProblem statement: An understanding of factors influencing entrepreneurial education in Iran’s applied-scientific educational centers for agriculture is crucial for creating the new opportunities for students and encouraging them to involve in entrepreneurial activity. The purpose of this study was twofold. First, it determined the key factors that influence entrepreneurial education in Iran’s applied-scientific educational centers for agriculture. Second, the study … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,234 accessesView PDFCite

Six hundred and seventy two of twelfth grade and 376 third-year vocational students were selected by multi-stage random sampling techniques. Approach: The instruments used for collecting data were: A scale on self-esteem, a … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Sum of Mixtures of Sum of Bivariate Exponential DistributionsAbd El-Moneim A.M. Teamah, Ahmed M.T. Abd El-BarProblem statement: The distributions of R = X+Y and W = X/(X+Y), where X and Y follow Lawrance and Lewis`s bivariate exponential distribution, is generalized. Approach: In this research we found mixtures of sum of bivariate exponential random variables. Results: Also we calculated the probability density function (pdf) of the random sum of mixtures of sum of bivariate exponential random … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,321 accessesView PDFCite
