this paper studies the effects of the structural variables of the iranian industries sector on the welfare cost using to the structure-conduct-performance (scp) theory. in other words, we investigate the role of structural components and their effects on the size of the welfare cost in iran's industry sector. we have used the leibenstein's model to calculate the deadweight loss and then the pan...

the set covering problem (scp) is a well-known combinatorial optimization problem. this paper investigates development of a local branching approach for the scp. this solution strategy is exact in nature, though it is designed to improve the heuristic behavior of the mixed integer programming solver. the algorithm parameters are tuned by design of experiments approach. the proposed method is te...

This paper presents a new worst-case analysis of heuristic approach to solve the Set Covering Problem (SCP) which is NP-hard. In this analysis Worst-case complexity and upper bound of solving SCP using this approach are presented.

This Article focuses on the Situational Crime Prevention (SCP) approach in criminology, which expands the crime reduction role well beyond the justice system. SCP sees criminal law in a more restrictive sense, as only part of the anticrime effort in governance. We examine the " general " and " specific " responses to crime problems in the SCP approach. Our review demonstrates that the most seri...

The self-clocking principle (SCP) of Transmission Control Protocol (TCP) had been analyzed for a network implementing a per-flow buffering scheme. The ideal SCP is yet unknown for the Internet which implements a first-in-first-out buffering scheme. This paper derives an ideal SCP for the Internet by formulating the traffic transmission control into a typical control problem and then solving it ...

Countless cybercrime instances have shown the need for detecting and blocking obscene material from social media sites. Deep learning methods (DLMs) outperformed in recognizing content flooded on many online platforms. However, these contemporary DLMs primarily treat recognition of as a simple task binary classification, rather than focusing labelling areas. Hence, could not pay attention to fa...

the potential of marine actinobacteria particularly streptomyces as a single cell protein (scp) feed for the growth of ornamental fish, xiphophorus helleri has been investigated. the streptomyces strains used as scp were isolated from the marine sponges, namely callyspongia diffusa , mycale mytilorum , tedania anhelans and dysidea fragilis . six scp feeds were prepared and their effects were co...

The Weighted Set Cover Problem (SCP) is a popular optimization problem that has been applied to different industrial applications, including scheduling, manufacturing, service planning and location problems. It consists in to find low cost solutions covering a set of requirements or needs. In this paper, we solve the SCP using a recent nature inspired algorithm: Invasive Weed Optimization (IWO)...
