Power Quality (PQ) combined disturbances become common along with ubiquity of voltage flickers and harmonics. This paper presents a novel approach to classify the different patterns of PQ combined disturbances. The classification system consists of two parts, namely the feature extraction and the automatic recognition. In the feature extraction stage, Phase Space Reconstruction (PSR), a time series analysis tool, is utilized to construct disturbance signal trajectories. For these trajectories, several indices are proposed to form the feature vectors. Support Vector Machines (SVMs) are then implemented to recognize the different patterns and to evaluate the efficiencies. The types of disturbances discussed include a combination of short-term disturbances (voltage sags, swells) and long-term disturbances (flickers, harmonics), as well as their homologous single ones. The feasibilities of the proposed approach are verified by simulation with thousands of PQ events. Comparison studies based on Wavelet Transform (WT) and Artificial Neural Network (ANN) are also reported to show its advantages.  相似文献

The present analysis performs a Multinomial Probit Model in order to observe which mobile technology qualifies across individuals. The findings indicate that individuals in family businesses prefer to combine both tablets and smartphones in their purchases, rather than separately. Younger individuals report an adoption preference towards smartphones, while older individuals are inclined towards tablets. The theoretical contributions encompass both the technology acceptance model (TAM) and the social cognitive theory (SCT). Individuals working in a family business exhibit a curious behaviour and they are becoming early adopters. TAM helps explain this behaviour as they tend to try new novelties exploring the potential usefulness they might derive; these technological advancements allow them to connect with customers and partners. By contrast, SCT helps gain a better understanding on young and old individuals' behaviour. The younger generations seem to be easily influenced by their peers with a tendency to technologies which are fun and allow them to build connections. Older individuals are equally influenced by their peers, with the difference that their social circle being more mature (e.g., business owners, professionals). This combined with the complexity of the technology orients them into adopting tablets more easily than smartphones.  相似文献

目的观察咪达唑仑预防腰-硬联合麻醉下妇科手术后恶心呕吐的效果。方法腰-硬联合麻醉妇科手术患者90例,随机分为M(咪达唑仑)组、G(格拉斯琼)组和NS组,手术结束时分别静注咪迭唑仑2mg,格拉斯琼3rag和生理盐水3ml,10min后开始硬膜外自控镇痛(PCEA),观察病人术后24h内恶心呕吐和镇静情况。结果NS组患者恶心呕吐总发生率(56.7%)显著高于其他两组(P〈0.01),M组(32.3%)和G组(24.1%)差异无统计学意义(P〉0.05)。术后2h时M组镇静程度高于C组和NS组(P〈0.05),但Ramsay评分均未超过3分;4h时3组病人镇静程度相近。结论腰-硬联合麻醉下行妇科手术的病人手术结束时静脉注射咪达唑仑2mg可以有效预防术后恶心呕吐,其效果和格拉斯琼3mg相似,且未表现出明显的镇静作用。  相似文献

We studied the feedback maximization of reliability of multi-degree-of-freedom (MDOF) quasi integrable-Hamiltonian systems under combined harmonic and white noise excitations. First, the partially averaged Ito equations are derived by using the stochastic averaging method for quasi integrable-Hamiltonian systems under combined harmonic and white noise excitations. Then, the dynamical programming equation and its boundary and final time conditions for the control problems of maximizing the reliability is established from the partially averaged equations by using the dynamical programming principle. The nonlinear stochastic optimal control for maximizing the reliability is determined from the dynamical programming equation and control constrains. The reliability function of optimally controlled systems is obtained by solving the final dynamical programming equation. Finally, the application of the proposed procedure and effectiveness of the control strategy are illustrated by using an example.  相似文献
