Abstract A systematic study on the microstructure evolution and kinetics analysis of PbO–SiO 2 slag reduction using hydrogen was conducted. The carried out pellets (70 wt pct PbO–30 SiO ; or 38.6 mol PbO 61.4 ) 15 pctH /85 pctN gas, with a flowrate 500mL/min for various reaction time (30 minutes to 3 hours) isothermally at 300 °C 700 °C. mechanism were assessed by measuring weight loss over app...

in this study, the profitability of contrarian and momentum strategies were traded in mid- term based on trading volume. the stocks were categorized into three parts (high, middle and low) at the outset. then, the relationship between excess return with three components such as cross-sectional risk, lead-lag effect and time-series pattern were examined based on jegadeesh and titman approach.the...

in this paper, the problem of determining the quality level, lead time for order delivery and price of a product produced by a manufacturer is considered. in this problem the demand for the product is influenced by all three decision variables: price, lead time and quality level. to formulate the demand function, a fuzzy rule base that estimates the demand value based on the three decision vari...

Binary Decision Diagram (in short BDD) is an efficient data structure which has been used widely in computer science and engineering. BDD-based attack in key stream cryptanalysis is one of the best forms of attack in its category. In this paper, we propose a new key stream attack which is based on ZDD(Zero-suppressed BDD). We show how a ZDD-based key stream attack is more efficient in time and ...

Business Process Management Systems (BPMS) is a complex information system that provides designing, administrating, and improving the business processes. Task allocation to human resources is one of the most important issues which should be managed more efficiently in BPMS. Task allocation algorithms are defined in order to meet the various policies of organizations. The most important of these...

Contextually probable, high-frequency, or easily accessible words tend to be phonetically reduced, a pattern usually attributed to faster lexical access. In principle, word forms that are frequent in their inflectional paradigms should also enjoy faster lexical access, leading again to phonetic reduction. Yet research has found evidence of both reduction and enhancement on paradigmatically prob...

<p style='text-indent:20px;'>To survive in today's competitive market, it is not enough to produce low-cost products but also quality-related issues and lead time needs be considered the decision-making process. This paper extends previous research by developing a stochastic economic manufacturing quantity (EMQ) model for production system which subject process shifts from an <i>in-...
