The high penetration of distributed generation(DG)has set up a challenge for energy management and consequently for the monitoring and assessment of power quality(PQ).Besides,there are new types of disturbances owing to the uncontrolled connections of non-linear *** stochastic behaviour triggers the need for new holistic indicators which also deal with big data of PQ in terms of compression and scalability so as to extract the useful information regarding different network states and the prevailing PQ disturbances for future risk assessment and energy management *** and continuous monitoring would guarantee the report to claim for damages and to assess the risk of PQ *** this context,we propose a measurement method that postulates the use of two-dimensional(2D)diagrams based on higher-order statistics(HOSs)and a previous voltage quality index that assesses the voltage supply waveform in a continous monitoring *** suitable for both PQ and reliability applications,the results conclude that the inclusion of HOS measurements in the industrial metrological reports helps characterize the deviations of the voltage supply waveform,extracting the individual customers’pattern fingerprint,and compressing the data from both time and spatial *** method allows a continuous and robust performance needed in the SG ***,the method can be used by an average consumer as a probabilistic method to assess the risk of PQ deviations in site characterization.

目的评价患者临床特征及实验室检查结果对18F-脱氧葡萄糖(FDG) PET/CT显像诊断不明原因发热(FUO)的影响。方法回顾性纵向分析FUO患者的PET/CT显像结果。参考标准为血清学检查、各种细菌培养或活组织检查结果,必要时参考其他实验室检查或临床随访结果。收集患者PET/CT显像近几天内的临床特征、炎性标志物、蛋白质分析、血清学检查和细菌培养结果。根据不同病因最终诊断分为3组:第1组为感染或肿瘤,第2组为脉管炎、自身免疫性疾病或非感染性炎性疾病,第3组为未明确诊断的自限性发热或持续性发热。PET/CT显像结果分为阳性或阴性、有助于或无助于诊断发热来源。分析患者临床特征和实验室检查结果对PET/CT结果的影响。结果 67例患者最终诊断分组为:第1组25例,第2组20例,第3组22例。89.6%的患者炎性标志物阳性,28.4%的蛋白质检测阳性,20.9%的细菌培养结果阳性。67例患者中,PET/CT显像阳性52例,25例有助于诊断发热来源,其中对第1组和第2组帮助尤其大。PET/CT显像的灵敏度、特异性和准确性分别为84%、31%和61%。PET/CT显像结果与最终诊断(P=0.035)和细菌培养结果(P=0.037)相关,而与其他临床特征或实验室检查结果无明显相关性。结论18F-FDG PET/CT显像诊断FUO的灵敏度高,但特异性低,可能的原因是FUO的病原范围很广,也有一些是自限性发热。最有可能从PET/CT显像获益的患者是那些多种炎性标志物阳性的患者,这些患者有活动性病变的可能性更高。
