| 1 | Fuzzy Chaos Control for Vehicle Lateral Dynamics Based on Active Suspension System显示文摘The existing research of the active suspension system(ASS) mainly focuses on the different evaluation indexes and control strategies. Among the different components, the nonlinear characteristics of practical systems and control are usually not considered for vehicle lateral dynamics. But the vehicle model has some shortages on tyre model with side-slip angle, road adhesion coefficient, vertical load and velocity. In this paper, the nonlinear dynamic model of lateral system is considered and also the adaptive neural network of tire is introduced. By nonlinear analysis methods, such as the bifurcation diagram and Lyapunov exponent, it has shown that the lateral dynamics exhibits complicated motions with the forward speed. Then, a fuzzy control method is applied to the lateral system aiming to convert chaos into periodic motion using the linear-state feedback of an available lateral force with changing tire load. Finally, the rapid control prototyping is built to conduct the real vehicle test. By comparison of time response diagram, phase portraits and Lyapunov exponents at different work conditions, the results on step input and S-shaped road indicate that the slip angle and yaw velocity of lateral dynamics enter into stable domain and the results of test are consistent to the simulation and verified the correctness of simulation. And the Lyapunov exponents of the closed-loop system are becoming from positive to negative. This research proposes a fuzzy control method which has sufficient suppress chaotic motions as an effective active suspension system. | HUANG Chen CHEN Long JIANG Haobin YUAN Chaochun XIA Tian | 2014 | Chinese Journal of Mechanical Engineering2014，27，4： | 5 |
| 2 | Nursing student perspectives of high-fidelity simulation in Macao显示文摘Objective The purpose of this study was to explore student perspectives of high-fidelity simulation.Methods A descriptive study with semi-structured focus group interviews was conducted in Macao.Twenty-one focus group interviews were held with 113 baccalaureate nursing students who had experienced 36-hour of simulation.Results Students perceived that simulation created a nonrisk learning environment,and was helpful in knowledge and skill enhancement and nurse role understanding.However,lack of realistic interactions in psychosocial responses made it difficult for students to relate simulation experience to real-working situations,and poor group contributions affected their learning.ConclusionInteracting with a human patient simulator does not replicate the experience of working with a live patient.Tutors need to come up with ideas about how to make scenarios more real and give more forthright responses to improve the realism of psychosocial responses during simulation.Students experienced uncertainty with clinical decision making and commented on the minimal contributions of some group members.Tutors should be prepared to provide students with substantial supports in developing their understanding of simulation and engaging in the learning process. | Haobin Yuan Beverly A Williams | 2015 | 护理学杂志(综合版)2015，30，4： | 2 |

| 4 | Psychological experience of infected individuals during the pandemic: A qualitative meta-synthesis显示文摘The purpose of this review is to integrate the psychological experience of infected individuals during the pandemic.The spread of the pandemic has led to psychological and emotional impacts on patients.A qualitative synthesis is needed to identify,appraise,and integrate the available qualitative findings to provide an evidence for the development of interventions.A meta-aggregation approach was used to analyze studies published in English from January 2020 to August 2021.The JBI Qualitative Assessment and Review Instrument was used to assess the methodological quality of included studies.The ConQual system was used to establish the dependability and credibility in the synthesized findings.Six phenomenological studies and one narrative inquiry with an overall quality score of 70%-100% were included.The research findings from 87 participants in eligible studies were aggregated into three categories based on similarity of meaning.Two synthesized findings were generated and rated as moderate based on the ConQual score.The synthesized findings suggested that participants had psychological distress such as fear,anxiety,loneliness,and uncertainty,but they accepted the fact of being infected and tried to adjust themselves using some self-coping strategies,such as diverting attention from disease,seeking help from professional counselors,relying on religious beliefs,and participating in religious activities.They would like to learn more about infections and diseases and needed more informational support from health-care professionals.They were looking forward to recovery from the disease. | Yao BIAN Haobin YUAN Wipada KUNAVIKTIKUL | 2022 | Journal of Integrative Nursing2022，4，2： | 0 |
| 5 | Self-directed learning readiness and social problem solving of nursing students in Macao显示文摘Objective The aims of this study were to describe nursing students′self-directed learning readiness and social problem solving and test their correlations in Macao.Methods This descriptive cross-sectional study was conducted on 140baccalaureate nursing students.A stratified random sampling was performed.The Self-directed Learning Readiness(SDLR)Scale and Chinese Social Problem-Solving Inventory-Revised(C-SPSI-R)were used.Results The response rate was 79.3%.Students possessed readiness for self-directed learning(mean 149.09±12.53,51.4%at high level,48.6%at low level).Regarding to social problem solving,the mean scores of each subscale were 9.35±3.25(Rational Problem Solving,RPS),10.26±3.23(Positive Problem Orientation,PPO),8.14±4.06(Negative Problem Orientation,NPO),5.67±4.44(Avoidance Style,AS),and 4.84±3.03(Impulsivity/Carelessness Style,ICS).SDLR was positively related to RPS and PPO,but was negatively related to AS.Conclusion Half of students possessed stronger readiness for self-directed learning.Students had a belief in the ability to solve problems,and adopted relevant strategies in solving problems.However,students still had negative and dysfunctional orientation and defective attempts in solving problems.Self-directed learning was positively related to positive and constructive orientation,but was negatively related to defective problem-solving pattern.Nurse educators should create educational climates for promoting student confidence and mutual responsibility for learning and their thinking process for problem solving. | Yuan Haobin | 2016 | 护理学杂志2016，31，1： | 0 |
