Proof testings are regularly conducted on safety instrumented systems (SISs) to reveal dangerous undetected (DU) failures so as to reduce process risks. Sometimes, self-diagnostic tests of SISs can find dangerous detected (DD) failures which will be fixed as soon as possible. If such detections of failures also activate further tests for all components in the SIS in order to discover hidden fai...

 Numerous problems in engineering and science can be converted into optimization problems. Artificial bee colony (ABC) algorithm is a newly developed stochastic optimization algorithm and has been widely used in many areas. However, due to the stochastic characteristics of its solution search equation, the traditional ABC algorithm often suffers from poor exploitation. Aiming at this weakness o...

At a time when the memory of Herbert Marcuse is fresh in the minds of many on the left, it is perhaps particularly fitting to focus our attention on the special place held in Marcuse's thought by the concept of memory. Many of his earlier commentators have, in fact, already noted its importance.' One of the more astute of their number, Fredric Jameson, even went so far as to claim that the theo...

in this study, one basic question will be answered: why were women officially considered being the subject of policy making decisions in reza khan era? the answer should be found in the particular logic of the discourse of that time which was “archeological nationalism”. the discourse is based on racist theory and understands social and cultural issues on the same basis. during the gap emerged ...

With the popularity of sensor networks, solving the knapsack problem has become important in selecting the best combination of sensor nodes. Many methods have been proposed to solve the Knapsack problem, but few of them have used the genetic algorithm, especially in unbounded Knapsack problems. In this paper, we use the genetic algorithm to solve the unbounded Knapsack problem. We combine an el...

This paper, commencing with the revision of classical concepts on democracy, puts forward that democracy is not only the aim but also a kind of means and method, based on which the paper further analyzes the shaping of democracy, and points out that elite democracy is an inevitable trend and that the role and function that elite democracy plays in the process of democratization is the exhibitio...

Elite crop varieties usually fix alleles that occur at low frequencies within non-elite gene pools. Dissecting these alleles for desirable agronomic traits can be accomplished by comparing the genomes of elite varieties with those from non-elite populations. Here we deep-sequence six elite rice varieties and use two large control panels to identify elite variety tag single-nucleotide polymorphi...
