One-parameter families of Newton’s iterative method for the solution of nonlinear equations and its extension to unconstrained optimization problems are presented in the paper. These methods are derived by implementing approximations through a straight line and through a parabolic curve in the vicinity of the root. The presented variants are found to yield better performance than Newton’s metho...

This paper presents an adaptive backoff algorithm for the contentionbased Distributed Coordination Function (DCF) of the IEEE 802.11 standard. Relying on on-line measurements of the number of sources, the algorithm, called Adaptive BEB, judiciously sets the size of the minimal contention window to adapt to the congestion level in the shared medium. The paper also provides an extension to Adapti...

The purpose of this study was investigation of East Azerbaijan researchers and extension agents’ view about the role of extension services on agricultural development. The methodology was descriptive-correlation which is carried out by survey method. In this study, the sample population was 335 people including all researchers and extension agents working in the agricultural sector. To assess t...

Shape correspondence is the foundation for accurate statistical shape analysis; this is usually accomplished by identifying a set of sparsely sampled and well-corresponded landmark points across a population of shape instances. However, most available shape correspondence methods can only effectively deal with complete-shape correspondence, where a one-to-one mapping is assumed between any two ...

the purpose of this study was to assess the process of extension program development in iranian agricultural extension system (iaes). the research instrument was a structural questionnaire with close-ended questions which its validity and reliability was confirmed by using expert panel and cranach’s alpha test, respectively. the target population of this research included all extension managers...
