In this paper, we study an (n-k+1)-out-of-n system by adopting their components to be statistically independent though nonidentically distributed. By assuming that at least m components at a fixed time have failed while the system is still working, we obtain the mixture representation of survival function for a quantity called the conditional inactivity time of failed components in the system. ...
Crop residues are beneficial substances that can bring about important changes in soil biological, chemical and physical properties and can also increase or stabilize crops yield. A field experiment was carried out at Research Station of College of Agriculture, Shiraz University, Shiraz, Iran, to determine the effects of wheat (Triticum aestivum L.) residue rates in combination with N levels on...
The present study was concerned with network failure problems for simple connected undirected graphs. A graph becomes unconnected through edge failure, under the assumptions that only edges can fail and each has an identical distribution. main purpose of to show recurrent relations respect number in generation procedures. To this end, graphs were correlated random K-out-of-N systems, key featur...
the aim of conducting this study was to investigate the foreign language learning needs of undergraduate economics students and business management students in faculties of social sciences of alzahra and azad naragh university. in the study, which was designed on the basis of a qualitative-quantitative basis using interviews and questionnaires, 146 female undergraduate business management as we...
Objective: A field experiment was conducted at Dorud region, Iran, during 2013. The aim of this research was study on effect of different biofertilizers and irrigation closed time on some agronomic characteristics of sugar beet (Beta vulgaris L.). Methods: The experimental design was factorial based on RCBD with three replications. Treatments were three irrigation closed time [Oct-6 (...

abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
This paper aimed to demonstrate the capabilities of decomposable semi-regenerative processes for investigation k-out-of-n system. Proposed in 1955 by W. Smith, regeneration idea has come a long way terms development and found widespread applications. First, we briefly recall history main results theory regenerative, semi-regenerative, processes. Then, methods are used study renewable system wit...
this research was carried out to evaluate the effects of irrigation methods and n fertilizer rates on the quantity and quality of sugar beet in ekbatan research station during 2001 and 2002. experiment was performed in split-plot with 3 replications and 15 treatments. treatments included 3 irrigation systems: sprinkler (solid set)، furrow (hydroflum) and drip (tape: 508-20-500) in main plots an...
