business related decisions become more perplexing as societies advance. environmental ambiguities which stem from new business models intensify the above mentioned complexity so far as many of the affecting variables and their interrelationships are non linear and complicated. in this circumstances data analysis and knowledge extraction is not practical via traditional methods. this research co...

web usage mining (wum) is the automatic discovering of hidden informationof user access pattern from the web log data. frequent pattern discovery is one ofthe main techniques in wum that can be used to implement recommender systems,forecast user`s navigational behaviour, and personalize web sites. many algorithmshave been suggested on obtaining frequent user navigation patterns. this paperprese...

Nowadays high fuzzy utility based pattern mining is an emerging topic in data mining. It refers to discover all patterns having a high utility meeting a user-specified minimum high utility threshold. It comprises extracting patterns which are highly accessed in mobile web service sequences. Different from the traditional fuzzy approach, high fuzzy utility mining considers not only counts of mob...

Background: High concentrations of various heavy metals of mine tailings can easily contaminate the environment. Such materials need monitoring and remediation to prevent them from polluting the environment and food chain. Materials & Methods: The concentrations of certain metals were evaluated in the soil samples at Sorkheh and Mazraeh copper mining areas in northwestern Iran, using three r...

Theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. They are typically in a non-equilibrium state with respect to their surroundings. Hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...

In the context of blockchain networks, mining describes a permissionless process intended to ensure global consistency decentralised ledger. Mining requires consumption costly computational resource participate in probabilistic competition that confers specific privileges node. These typically relate proposal new block, including identity and order transactions contained within. is incentivised...

a long-term study was conducted between 1985 and 2003 on rehabilitation trials at sishen ironore mine, south africa, to identify grass species that would survive in the artificial growth medium appliedto the sites, and to determine the most suitable medium for sustainable vegetation growth. vegetationestablishment was tested at slopes of 18° and 34° and with five different cover materials. afte...
