| 1 | Human factors quantification via boundary identification of flight performance margin显示文摘A systematic methodology including a computational pilot model and a pattern recognition method is presented to identify the boundary of the flight performance margin for quantifying the human factors. The pilot model is proposed to correlate a set of quantitative human factors which represent the attributes and characteristics of a group of pilots. Three information processing components which are influenced by human factors are modeled: information perception, decision making, and action execution. By treating the human factors as stochastic variables that follow appropriate probability density functions, the effects of human factors on flight performance can be investigated through Monte Carlo(MC) simulation. Kernel density estimation algorithm is selected to find and rank the influential human factors. Subsequently, human factors are quantified through identifying the boundary of the flight performance margin by the k-nearest neighbor(k-NN) classifier. Simulation-based analysis shows that flight performance can be dramatically improved with the quantitative human factors. | Yang Changpeng Yin Tangwen Zhao Weina Huang Dan Fu Shan | 2014 | Chinese Journal of Aeronautics2014，27，4： | 3 |
| 2 | A new real-time algorithm for off-road terrain estimation using laser data显示文摘Gaussian mixture algorithm(GMA) is an effective approach for off-road terrain estimation,but still suffers from some difficulties in practical applications,such as complex calculation and object abstraction. In this paper,GMA is modified to improve its real-time performance and to provide it with a potential ability of obstacle detection. First,a selection window is designed based on the dominant-ellipse-principle to limit the probability distribution area of each measurement point,therefore avoiding the calculation on the cells outside the dominant ellipse. Second,a clustering approach is proposed in order to distinguish objects efficiently and decrease the operation area of one laser scan. Third,a virtual point vector is introduced to further reduce the computational load of the mean square error matrix. The modified GMA is experimented on a tracked mobile robot,and its improved performance is shown in comparison to the original GMA. | QIU Quan YANG TangWen HAN JianDa | 2009 | Science in China(Series F)2009，52，9： | 2 |

| 4 | Modeling the COVID-19 Outbreak in China through Multi-source Information Fusion显示文摘Modeling the outbreak of a novel epidemic,such as coronavirus disease 2019(COVID-19),is crucial for estimating its dynamics,predicting future spread and evaluating the effects of different interventions.However,there are three issues that make this modeling a challenging task:uncertainty in data,roughness in models,and complexity in programming.We addressed these issues by presenting an interactive individual-based simulator,which is capable of modeling an epidemic through multisource information fusion. | Lin Wu Lizhe Wang Nan Li Tao Sun Tangwen Qian Yu Jiang Fei Wang Yongjun Xu | 2020 | The Innovation2020，1，2： | 1 |
| 5 | Identification of tissue types and boundaries with a fiber optic force sensor显示文摘The absence of tactile force information at the tip of a medical instrument makes precise minimally invasive surgery difficult and is prone to resulting in serious outcomes.In this paper,a fiber optic force sensor is fabricated based on Fabry-P′erot interferometry and integrated with a puncture needle.The force sensor is attached to the needle tip,where interactive force arises as it inserts into soft tissue.Needle insertion experiments have been conducted on ex vivo swine liver and belly with the calibrated force sensor.Using wavelet transform method,the acquired force data are analyzed and used to identify layered tissue types and boundaries.We found that the force amplitudes are not always identical,but the patterns of forces are almost the same,which enables us to identify layered tissues and to realize a safe needle insertion procedure under robot control. | YANG TangWen ZHU HaiFeng HAN JianDa ZHAO XinGang XU WeiLiang | 2014 | Science China(Information Sciences)2014，57，12： | 1 |
