Stochastic comparison results for replacement policies are shown in this paper using formalism of point processes theory. At each failure moment a repair is allowed performed with a random degree of repair including as special cases perfect, minimal, imperfect repair models. Results for such repairable systems with schemes of planned replacements are also shown. The results are obtained by coup...

In this concluding part of a series of papers on tetrahedral polynomial extension operators, the existence of a polynomial extension operator in the Sobolev space H(div) is proven constructively. Specifically, on any tetrahedron K, given a function w on the boundary ∂K that is a polynomial on each face, the extension operator applied to w gives a vector function whose components are polynomials...

the main purpose of this was to analyze challenges and improvement mechanisms of wheat consulting engineers (wces) in iran, isfahan provinces. it was based on survey research which has been two groups (consulting engineers and extension experts). the population of the study was 163 of wheat consulting engineers and 87 extension experts. out of which, 95 consulting engineers and 55 extension exp...

the general purpose of this article is to identify the influencing factors on rural women participation inagricultural extension programs in mazandaran province. therefore, using multi-stage sampling, 300 ruralwomen were selected randomly. the research instrument was a semi-structured questionnaire. results showthat rural women participation in agricultural extension programs is at average leve...

The interest of the paper lies in taking advantage of multi-parameter measurement capability to improve or assess microphysical phenomena knowledge. The data interpretation is quite consistent and well referenced, and recent and interesting approaches are used (e.g. QVP by Ryzhkov et al., 2016). However, even if the paper aims at presenting some preliminarily step to some more ambitious study (...

We have found that the single nucleotide primer extension assay, a PCR-based assay currently used qualitatively to measure allelic differences in DNA, can be used quantitatively to measure allele-specific transcripts differing by only a single nucleotide. We show that total RNA containing the Pgk-1a transcript can be specifically detected even in a 1000-fold excess of RNA containing the Pgk-1b ...

Supply chain partnership involves mutual commitments among participating firms. One example is early order commitment, wherein a retailer commits to purchase a fixed-order quantity and delivery time from a supplier before the real need takes place. This paper explores the value of practicing early order commitment in the supply chain. We investigate the complex interactions between early order ...

The goal of bandwidth extension of speech (BWE) is to extrapolate the missing low or high frequency components of the wide-band speech (50-8000 Hz) based entirely on information contained in a narrow-band signal (300-3400 Hz). In this paper we propose a new method for high-frequency regeneration of the excitation signal, using the correlation between the shape of the glottal flow waveform and t...
