Study of CNG/diesel dual fuel engine's emissions by means of RBF neural network     

刘震涛  费少梅 《浙江大学学报(A卷英文版)》2004,5(8):960-965

Great efforts have been made to resolve the serious environmental pollution and inevitable declining of energy resources. A review of Chinese fuel reserves and engine technology showed that compressed natural gas (CNG)/diesel dual fuel engine (DFE) was one of the best solutions for the above problems at present. In order to study and improve the emission performance of CNG/diesel DFE, an emission model for DFE based on radial basis function (RBF) neural network was developed which was a black-box input-output training data model not require priori knowledge. The RBF centers and the connected weights could be selected automatically according to the distribution of the training data in input-output space and the given approximating error. Studies showed that the predicted results accorded well with the experimental data over a large range of operating conditions from low load to high load. The developed emissions model based on the RBF neural network could be used to successfully predict and optimize the emissions performance of DFE. And the effect of the DFE main performance parameters, such as rotation speed, load, pilot quantity and injection timing, were also predicted by means of this model. In resume, an emission prediction model for CNG/diesel DFE based on RBF neural network was built for analyzing the effect of the main performance parameters on the CO, NOx emissions of DFE. The predicted results agreed quite well with the traditional emissions model, which indicated that the model had certain application value, although it still has some limitations, because of its high dependence on the quantity of the experimental sample data.  相似文献

Affordances of narrative and numerical data: A social-semiotic approach to data use     

《Studies in Educational Evaluation》2021

Data use in education is a sensemaking process in which practitioners and researchers interact with different systems of meaning such as anecdotes or spreadsheets. The representational qualities of data and their influence on practice are critical but less well-discussed aspects of data use. Drawing on social semiotics, this theoretical article proposes that data should be discussed in terms of narrative and numerical modes of representation. Narrative data typically consist of protagonists and actions organized in a temporal structure, while numerical data typically consist of mathematical notations and visual representations such as graphs and figures. We argue that the representational properties of these two modes affect how data are interpreted and acted upon. We then present two contrasting cases from New Zealand and Norway of how affordances affect teachers’ data use processes. Finally, we discuss five challenges arising from our theorization about the affordances of data.  相似文献   

Teacher judgments at zero-acquaintance: A social accuracy analysis     

《Contemporary educational psychology》2021

How accurate are teachers’ first impressions and what moderates the degree of first impression accuracy? In previous teacher judgment accuracy research, teachers judged students who were well-acquainted to them, focusing on single traits. Here, we follow the zero-acquaintance paradigm and apply the Social Accuracy Model (SAM; Biesanz, 2010) to examine teachers’ first impressions regarding students’ personality profiles. Three groups of perceivers (student teachers, experienced teachers and psychology students; N = 285) rated students’ (N = 10) academic self-concept, intrinsic motivation and intelligence based on brief videos. SAM analyses revealed that teachers were accurate regarding the average students’ profile of characteristics (normative accuracy), but were not successful at detecting students' unique personality profiles (distinctive accuracy). Moreover, likeable students and those evaluated as more physically attractive were perceived with higher normative accuracy. Personality similarity and teaching experience were unrelated to accuracy. Implications for teacher judgment accuracy research and educational practice are discussed.  相似文献   

Compelled to Compete: Chinese graduates on employment and social mobility after international and domestic study     

《International Journal of Educational Development》2021

The article offers unique insights into international and domestic graduates’ career progression and social mobility experiences in China. Drawing on in-depth interview data with master-level graduates, the analytical results reveal that the majority of the participants (both domestic and international) perceive that international graduates have more opportunities and better career progression, but the analytical results show that both domestic and international graduates secured positive employment outcomes. Significant gender disparities exist, as women, both international and domestic graduates, are still disadvantaged in terms of occupational attainment and career prospects and report lower employment satisfaction. All domestic graduates reported not only positive employment outcomes in the labour market but upward social mobility. In contrast, the majority of international graduates reported not having achieved the same level of social status as their parents. Graduates’ differentiated relations to China’s state institutions of Bianzhi, Danwei and Hukou and social connections (Guanxi) heavily influenced their employment trajectories and social mobility. We argue that the participants’ conflicting perceptions are linked to the intense labour market competition encouraged by the sustained expansion of domestic higher education enrolment and amplified by the increasing number of international graduates. The societal institutions defuse to some extent conflicts over economic interests arising from the marketisation of social life.  相似文献

自建流程式实习的理论、应用及效能     

王成江  陈铁 《高等工程教育研究》2021,(2):88-93

现阶段,网络教学在大学中越来越普遍,尤其是疫情全国"封城"期间,网络教学成为大学教学模式的唯一选择。网络教学模式下,工程类大学生无法进驻企业进行生产实习,虚拟仿真培训又是验证性实验而效能不佳。基于生产设备的实物照片和生产过程的生产流程,结合图像处理技术,提出了工程类专业实习的纾困方案——自建流程式实习。文章研究了自建流程式实习的理论基础和内涵定义,重点探讨了自建流程式实习的应用过程,分析了自建流程式实习的效能及实习目标的达成情况。效能分析表明,自建流程式实习可以加深工程类大学生对生产设备和生产过程的感性认识,还可以提高他们的动手创作和设计优化能力,是解决网络教学模式下工程类大学生生产实习困境的可行出路。  相似文献
