A Practical Exploration of Process Assessment Teaching Reform

In order to effectively promote higher education reform,colleges and universities should focus not only on basic knowledge learning,but also on improving students’quality,skills,and comprehensive literacy.Through practical experience,it can be seen that the cultivation of students’comprehensive quality needs to be implemented in all teaching links,among which the assessment link is no exception.In order to enhance the effectiveness and advanced nature of the teaching evaluation mechanism,it is necessary for colleges and universities to reform the real-time process assessment.Other educational departments should also pay more attention and place importance on this work,integrating it with the curriculum to optimize the evaluation link.

A Systematic Risk Assessment Framework of Automotive Cybersecurity

The increasingly intelligent and connected vehicles have brought many unprecedented automotive cybersecurity threats,which may cause privacy breaches,personal injuries,and even national security issues.Before providing effective security solutions,a comprehensive risk assessment of the automotive cybersecurity must be carried out.A systematic cybersecurity risk assessment framework for automobiles is proposed in this study.It consists of an assessment process and systematic assessment methods considering the changes of threat environment,evaluation target,and available information in vehicle lifecycle.In the process of risk identification and risk analysis,the impact level and attack feasibility level are assessed based on the STRIDE model and attack tree method.An automotive cybersecurity risk matrix using a global rating algorithm is then constructed to create a quantitative risk metric.Finally,the applicability and feasibility of the proposed risk assessment framework are demonstrated through a use case,and the results prove that the proposed framework is effective.The proposed assessment framework helps to systematically derive automotive cybersecurity requirements.

Research on the Practical Teaching of Data Structures and Algorithms Course

The success or failure of practical teaching in data structures and algorithms coxirse determines the success or failure of the course group.The reform of practical teaching in this course takes the course group as the background and aims to meet the needs of students at different levels.It proposes a hierarchical practical teaching mode involving three levels in terms of foundation,design,and synthesis driven by cases throughout the whole course group and a fine process control mechanism based on multi-stage process assessment.

Greenhouse gas emission and its potential mitigation process from the waste sector in a large-scale exhibition

As one of the largest human activities, World Expo is an important source of anthropogenic Greenhouse Gas emission（GHG）, and the GHG emission and other environmental impacts of the Expo Shanghai 2010, where around 59,397 tons of waste was generated during 184 Expo running days, were assessed by life cycle assessment（LCA）. Two scenarios, i.e., the actual and expected figures of the waste sector, were assessed and compared, and 124.01 kg CO2-equivalent（CO2-eq.）, 4.43 kg SO2-eq., 4.88 kg NO-3-eq., and 3509 m3 water per ton tourist waste were found to be released in terms of global warming（GW）, acidification（AC）,nutrient enrichment（NE） and spoiled groundwater resources（SGWR）, respectively. The total GHG emission was around 3499 ton CO2-eq. from the waste sector in Expo Park, among which 86.47% was generated during the waste landfilling at the rate of 107.24 kg CO2-eq.,and CH4, CO and other hydrocarbons（HC） were the main contributors. If the waste sorting process had been implemented according to the plan scenario, around 497 ton CO2-eq.savings could have been attained. Unlike municipal solid waste, with more organic matter content, an incineration plant is more suitable for tourist waste disposal due to its high heating value, from the GHG reduction perspective.
