摘要：
This study introduces the mathematical model of a new type of power system stabiliser PSS4B-W. The concept of crossbreed in genetic algorithm is introduced to particle swarm optimisation algorithm and applied to PSS4B-W parameter optimisation. With a PCS-9410 excitation regulator, the semi-physical simulation system is constituted on a real time digital simulator (RTDS) platform. By measuring the excitation system phase frequency characteristic without compensation, the PSS4B-W parameter optimisation is converted to a set of parameters optimisation process with inequality constraint. In the RTDS platform, the time-domain dynamic response of without PSS, adding PSS2B and PSS4B-W, is compared and analysed. Simulation results show that the optimised PSS4B-W can provide effective damping in different frequency bands, and have good inverse-regulation suppression effect.

摘要：
WirelessSensor Network systems (WSNs) have received noteworthy research consideration because of their elite qualities like broad capacity to detect the physical world phenomenon and their broad scope of utilizations, extensive variety of uses due to low cost. One of the real requirements of WSN is lifetime of system because of its battery usage. To determine this issue to some degree is solved by creating various approaches on routing protocol to make energy efficient. EESR-ART2 approach is an endeavor to make organize vitality proficient. ART2 Neural Network Technique is actualized with Energy Efficient Sensor Routing (EESR) Protocol that observed to be a much viable outcome in recreation and upgrade the system lifetime regarding FND (first node dead) and HNA (half node alive) when contrasted with different protocols. Security is the major challenge faced by the existing WSN system. This paper focuses on intrusion detection in energy efficient sensor network using neuro-fuzzy approach. The proposed model discusses how anomalies detection scheme is improved using neuro-fuzzy approach.

摘要：
As the field of data science grows, document analytics has become a more challenging task for rough classification, response analysis, and text summarization. These tasks are used for the analysis of text data from various intelligent sensing systems. The conventional approach for data analytics and text processing is not useful for big data coming from intelligent systems. This work proposes a novel TF/IDF algorithm with the temporal Louvain approach to solve the above problem. Such an approach is supposed to help the categorization of documents into hierarchical structures showing the relationship between variables, which is a boon to analysts making essential decisions. This paper used public corpora, such as Reuters-21578 and 20 Newsgroups for massive-data analytic experimentation. The result shows the efficacy of the proposed algorithm in terms of accuracy and execution time across six datasets. The proposed approach is validated to bring value to big text data analysis. Big data handling with map-reduce has led to tremendous growth and support for tasks like categorization, sentiment analysis, and higher-quality accuracy from the input data. Outperforming the state-of-the-art approach in terms of accuracy and execution time for six datasets ensures proper validation.

摘要：
With the rapid development of the wide area measurement system（WAMS）, the disturbance source location method based on oscillation energy has been widely used in low frequency oscillation monitoring. This paper focuses on the applicability research of different oscillation energy methods. Taking the forced power oscillation caused by the excitation system abnormality as an example, the disturbance source location accuracy of three oscillation energy methods is compared. The results show that it is important to extract the dominant component of the electrical signal. When the non-dominant component content is large, it will affect the location accuracy of the traditional oscillation energy method.
摘要：
A new genus with a new species of the tribe Hoplocampini of Hoplocampinae was described from China: Analcellicampa xanthosoma Wei & Niu, gen. et sp. nov. Hoplocampa danfengensis G. Xiao 1994 was designated as the type species of the new genus. The characters of Analcellicampa danfengensis (G. Xiao) comb. nov. were briefly discussed. A key to the tribes and known genera of Hoplocampinae was provided. The nearly complete mitochondrial genome of A. xanthosoma was characterized as having a length of 15,512 bp and containing 37 genes (22 tRNAs, 13 protein-coding genes (PCGs), and 2 rRNAs). The gene order of this new specimen was the same as that in the inferred insect ancestral mitochondrial genome. All PCGs were initiated by ATN codons and ended with TAA or T stop codons. All tRNAs had a typical cloverleaf secondary structure, except for trnS1. Remarkably, the helices H991 of rrnS and H47 of rrnL were redundant, while helix H563 of rrnL was highly conserved. A phylogeny based on previously reported symphytan mitochondrial genomes showed that A. xanthosoma is a sister group to Monocellicampa pruni, with high support values. We suggest that A. xanthosoma and M. pruni belong to the tribe Hoplocampini of Hoplocampinae.

摘要：
In this letter, compact ultra-wideband filters are designed by employing a novel ridged half-mode folded substrate-integrated waveguide (RHMFSIW) and double-ridged half-mode SIW (DRHMSIW). The RHMFSIW is proposed by loading the half-mode folded substrate integrated waveguide with a ridge, where the ridge introduces additional capacitance hence leading to a lower cutoff frequency and a smaller size. Compact ultra-wideband filters are designed and fabricated based on the RHMFSIW. Another novel DRHMSIW is developed to implement the tight coupling required in the ultra-wideband filters. To improve the out-of-band rejection while keeping a small size, mixed coupling is employed in the ultra-wideband filter to generate transmission zeros. The proposed filters demonstrate the advantage of high selectivity, low loss, compact size, and easy integration with other electronic systems.

摘要：
The permanent magnet synchronous machines (PMSMs) have been used in a variety of different industrial applications. The transient parameters of the PMSM determine the safe operation and stability of the whole system. This paper introduces Hilbert-Huang transform (HHT) to identify the transient parameters of the PMSM. First of all, based on three-phase sudden short-circuit current, the DC and AC components from the transient current are extracted by using empirical mode decomposition (EMD). Then, by performing curve fitting on the envelope of DC and AC components separately, the transient parameters of the PMSM are obtained. Finally, the current waveform based on identification parameters is compared with the finite element (FE) current waveform to verify the effectiveness of the identification method.
