government interventions in agricultural markets in order to stabilize commodity prices and producer incomes have had a long tradition. intervention has been at both the state and country levels and has been for the most part in the form of commodity-based schemes. this study represents an attempt to develop an appropriate methodology for analyzing the aggre-gate effects of a particular type of...
the frobenius complement of a given frobenius group acts on its kernel. the scheme which is arisen from the orbitals of this action is called ferrero pair scheme. in this paper, we show that the fibers of a ferrero pair scheme consist of exactly one singleton fiber and every two fibers with more than one point have the same cardinality. moreover, it is shown that the restriction of a...
The purpose of this paper is to introduce Kirk-type new iterative schemes called Kirk-SP and Kirk-CR schemes and to study the convergence of these iterative schemes by employing certain quasi-contractive operators. By taking an example, we will compare Kirk-SP, Kirk-CR, Kirk-Mann, Kirk-Ishikawa, and Kirk-Noor iterative schemes for aforementioned class of operators. Also, using computer programs...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
Four explicit finite difference schemes, including Lax-Friedrichs, Nessyahu-Tadmor, Lax-Wendroff and Lax-Wendroff with a nonlinear filter are applied to solve water hammer equations. The schemes solve the equations in a reservoir-pipe-valve with an instantaneous and gradual closure of the valve boundary. The computational results are compared with those of the method of characteristics (MOC), a...
Mobile social networks (MSNs) are a special type of Delay tolerant networks (DTNs) in which mobile devices communicate opportunistically to each other. One of the most challenging issues in Mobile Social Networks (MSNs) is to design an efficient message forwarding scheme that has a high performance in terms of delivery ratio, latency and communication cost. There are two different approaches fo...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
We propose two fault-tolerant broadcasting schemes in star graphs. One of the schemes can tolerate up to n − 2 faults of the crash type in the n-star graph. The other scheme can tolerate up to ⌊ n−3d−1 2 ⌋ faults of the Byzantine type in the n-star graph, where d is the smallest positive integer satisfying n ≤ d!. Each of the schemes is designed for the single-port mode, and it completes the br...
