Based on the results of the 5-consecutive-year experiments,a reasonable irrigation model for wheat cultivation is suggested according to the principle of maintaining balance of the water resources. The irrigation program was designed by simulating the ideal soil moisture regimes during a wheat season. As far as the actual soil moisture was concerned, its deyiation from the ideal soil moisture was kept within 150 mm. If this model was put into practice, a grain yield of 5 250 kg ha-1 could be expected under optimal fertilization. Compared with the traditional irrigstion scheme, the suggested model saved irrigation water by 18%.展开更多

Alarm root-cause analysis and alarm prioritization are good for alarm flood reduction. This paper proposes a systematic rationalization method for multivariate correlated alarms to realize the root cause analysis and alarm prioritization. An information fusion based interpretive structural model is constructed according to the data-driven partial correlation coefficient calculation and process knowledge modification. This hierarchical multi-layer model is helpful in abnormality propagation path identification and root-cause analysis. Revised Likert scale method is adopted to determine the alarm priority and reduce the blindness of alarm handling. As a case study, the Tennessee Eastman process is utilized to show the effectiveness and validity of proposed approach. Alarm system performance comparison shows that our rationalization methodology can reduce the alarm flood to some extent and improve the performance.展开更多

It is observed that the model is too restrictive in its explaining events and behavior in social and political situations. It is suggested that the assumptions of RM model should be relaxed using the familiar methods and techniques of elementary formal logic. The concept of relevance is then introduced to take account of a ＂weaker＂ formal requirement in an attempt to explain events and processes in human action and/or behavior. The concept of ＂justification by reasons＂ is then introduced as a necessary though not sufficient requirement of explaining events and processes in social and political studies展开更多

The participants were randomly assigned to the treatment and the control group. Both groups received a pre- and post- test of their Speaking Anxiety （SA）, Speaking State Anxiety （SAstate） as well as speaking performance. Those involved in the treatment group also received a treatment with the SARM between the tests. The results showed that, with the effects of Language Achievement （LA） being controlled： （1） the SARM could significantly reduce the SA, SAstate, and increase the total number of words in Communication Units （CUs）; and （2） the effects of the SARM did not differ significantly in terms of gender.展开更多
