Dynamic Gesture Recognition Based on DS Evidence Theory

低场核磁共振仪器振铃抑制新方法及其电路实现

第三十九届中国控制会议

作者： Haoxin Lei Yanhong Liu Lei Yang School of Electrical Engineering Zhengzhou University Robot Perception and Control Engineering Laboratory in Henan Province

Dynamic gesture recognition is gradually playing an increasingly important role in non-contact human-computer interaction. It is important to improve the accuracy of the recognition while reducing the computational cost. In this paper, we consider the dynamic gesture recognition based on multiple feature extraction and Dempster-Shafer（DS） evidence theory. First,to improve the accuracy of the gesture recognition, HOG2＆HOG-LBP features are extracted and used for the training of Support Vector Machines（SVM）. Then, DS evidence theory is used to optimize the classification results of SVMs. Experimental results on the cambridge Hand Gesture Dataset demonstrate the effectiveness of the proposed method.

加快天线残余能量释放以减弱天线振铃信号有利于缩短低场核磁共振仪器的回波间隔(TE),从而提高快弛豫组分的测量分辨率和信噪比(SNR).而天线Q值对能量的发射效率和泄放速度起着相反的作用.为此,我们首先设计了一种新型Q转换电路,在保证发射效率的同时,可以大大缩短能量泄放时间.在此基础上,应用了一种优化的脉冲序列以弥补传统相位交替对脉冲序列(PAPs)不能消除90脉冲振铃的缺陷,通过相位循环的方法进一步提高了信噪比.最后,在2 MHz岩心分析仪上测试了新型Q转换电路,当天线Q值降为发射期间的约1/5时,天线恢复时间由280.0μs降为18.2μs;而且,使用新型Q转换电路和优化的脉冲序列后,TE=60μs时,可以有效获得快弛豫组分的T2信号.

Aim: To compare diagnostic accuracy of procalcitonin for early diagnosis of s erious bacterial infection (SBI) in children presenting with fever and no focus of infection. Methods: Prospective, observational study involving 72 children (1 - 36 mo) presenting to the paediatric units of two university hospitals. All ch ildren had blood cultures, urine cultures, white blood cell counts (WBC), chest X- ray, C- reactive protein (CRP)- and procalcitonin (PCT) done at presentati on. Results: Eight (11.1% ) children had SBI (1 pneumonia, 2 meningitis, 4 sept icaemia/ occult bacteraemia, 2 pyelonephritis), 19 (26.4% ) had possible bacter ial infection (received antibiotic treatment, but no organism grown) and 45 (62. 5% ) had viral or possible viral infection (virus isolated and/or uneventful re covery without antibiotics). PCT (> 2 ng/l), CRP(>50 mg/l) and McCarthy’s scor e ( 5 0 mg/l), PCT ( > 2 ng/l), white blood cells ( > 15 × 109/l) and McCarthy’s score ( < 9)were 0.36/2.4, 0.58/ 3.5, 0.94/1.1 and 0.19/2.7, respectively. A com bination of PCT, CRP and WBC generated a positive likelihood ratio of 10.6, chan ging the post- test probability to 54% . Conclusion: For early diagnosis of SB I in children presenting with fever and no focus of infection, the diagnostic ut ility of procalcitonin is similar to the traditional markers infection and clini cal scoring. While a low procalcitonin level cannot be used to exclude SBI in th is population, a combination of PCT, CRP and WBC may be more useful in predictin g SBI.

目的:分析人类白细胞抗原(HLA)等位基因与鼻咽癌(NPC)患者临床特征的关系,探讨二者对NPC5年生存预后的影响。方法:回顾性总结231例潮汕地区NPC患者的HLA-A、-B等位基因分型并收集其临床特征信息。HLA-A、-B等位基因与NPC患者临床特征的相关性采用二分类Logistic回归分析;用Kaplan-Meier方法进行生存估计,用Cox比例风险模型进行生存分析。结果:Cox单、多因素分析均显示,在临床Ⅲ～Ⅳ期NPC患者中,HLA-A*24携带者的5年生存率明显低于HLA-A*24非携带者(P<0.05,RR=1.710,95%CI=1.052-2.780和P<0.05,RR=1.825,95%CI=1.117-2.981),提示HLA-A*24为NPC的独立预后因素;此外,年龄、抽烟、临床分期,以及T、N、M分期等也都是影响NPC预后的重要因素(P≤0.05);但HLA-A、-B等位基因与NPC患者临床特征并无显著性相关。结论:处于临床Ⅲ～Ⅳ期的NPC患者,HLA-A*24携带者的预后较非携带者要差,临床检测HLA-A*24对判断NPC患者的预后可能会有所帮助。
