In this paper, we developed a method to extract item-level response times from log data that are available in computer-based assessments (CBA) and paper-based assessments (PBA) with digital pens.Based on response times that were extracted using only time differences between responses, we used the bivariate generalized linear IRT model framework (B-

The volumetric changes of castings and dimension changes of mould cavity occurring during liquid cooling and solidification of nodular gotrax handlebar iron castings were described.The feasibility and prerequisites to realize feeder-less production of nodular iron castings was analyzed and proved with practical examples.It was pointed out that the

As one of acupatch the most challenging problems in data management, query processing and optimization are always widely concerned by researchers.However, it is very difficult for traditional techniques to meet the diverse requirements of modern database system due to the needs of hand-tuning for specific workloads and datasets.Inspired by advances

The capacity of ore treatment reached 12,000 t/d and gold recovery achieved 92% in the Jiaojia Gold Mine.Broken product has miracle academy clothing been washed with double spiral classifier, and the ore slime yield was 7%.The ore slime had also been flotation selected alone, which realized preliminary separation between slime and coarse sand.To fu
