A flow cache is a fundamental building block for flowbased traffic processing. Its efficiency is critical for the overall performance of a number of networked devices and systems. The efficiency is mainly dependent on a utilized replacement policy. This work proposes an approach based on Genetic Algorithm. The proposed approach starts from recorded traffic traces and uses Genetic Algorithm to e...

The control of a stochastic manufacturing system that executes capital asset repairs and remanufacturing in an integrated system is examined. The remanufacturing resources respond to planned returns of worn-out equipments at the end of their expected life and unplanned returns triggered by major equipment failures. Remanufacturing operations for planned demand can be executed at different rates...

BACKGROUND Support for smoke-free policies increases over time and particularly after implementation of the policy. In this study we examined whether the comprehensiveness of such policies moderates the effect on support among smokers. METHODS We analysed two waves (pre- and post-smoke-free legislation) of the International Tobacco Control (ITC) surveys in France, Germany, and the Netherlands...

INTRODUCTION Little research has been conducted to determine the psychosocial and behavioral impacts of smoke-free policies in middle-income countries. METHODS Cross-sectional data were analyzed from the 2006 waves of the International Tobacco Control Policy Evaluation. Survey comparing adult smokers in Mexico (n = 1,080), where smoke-free legislation at that time was weak, and Uruguay (n = 1...

Novel replacement policies that are hybrids of inspection maintenance and block replacement are developed for an n component series system in which the component parts used at successive replacements arise from a heterogeneous population. The heterogeneous nature of components implies a mixed distribution for time to failure. In these circumstances, a hybrid policy comprising two phases, and ea...

Prefetching is an inbuilt feature of file system and storage caches. The cache replacement policy plays a key role in the performance of prefetching techniques, since a miss occurs if a prefetch block is evicted before the arrival of the on-demand user request for the block. Prefetch blocks display spatial locality, but existing cache replacement policies are designed for blocks that display te...

UNLABELLED Secondhand smoke is harmful to smokers and nonsmokers, and smoke-free legislation worldwide improves health status. Lebanon has one of the weakest tobacco control regulatory environments in the Eastern Mediterranean region. However, several Lebanese workplaces and hospitality venues have chosen to implement such policies on their own. The objective of this study was to document their...
