A Semi-Analytical Method for the Identification of DC-Decay Parameters at an Arbitrary Rotor Position in Large Synchronous Machines by Zhenming Lai, Haoyu Kang, Demin Liu, Zhichao Wang, Yong Yang, Jin Wang

“…Compared to the results obtained by the TPSSC test using the Prony algorithm and other conventional type tests, the error of the parameter calculation results obtained with the conventional method reached a maximum of 16.6%, while that of the proposed method was merely 8.6%, and the experimental period could be shortened from 5 days to half a day.…”

Enrichment of electrotrophic microorganisms from contrasting shallow-sea hydrothermal environments in bioelectrochemical reactors by Antoine Carissimo, Victoria Comes, Alenica Heussner, Anne-Hélène Prime, Roy E. Price, Gaël Erauso, Pierre-Pol Liebgott, Sven Kerzenmacher, Guillaume Pillot

“…Bioelectrochemical reactors can be used to investigate such electrotrophic diversity by providing an electrode as an electron donor.MethodsHere, a total of 60 different reactors were set up and inoculated with either a microbial community coming from the shallow, acidic (ca. pH 5.5) and hot (ca. 120°C) hydrothermal system of Panarea, Aeolian islands, Italy, or the shallow, alkaline (pH 11) and mild (40°C) hydrothermal system of Prony Bay, New Caledonia.ResultsWith the alkaline sample, no electrical current increase was seen in any of the 15 reactors operated for 6 days under Prony hydrothermal conditions (pH 10, 30–75°C). …”

A Novel Hybrid Algorithm for Transient Near-Field Scattering from Rough Surface in 2-D Case by Wei Tian, Bing Wei, Qian Yang

“…In this paper, the 2-D time-domain Green’s function as the convolution kernel is approximated with a sum of exponential terms by using the Prony’s method. Then, the semianalytical recursive convolution (SARC) approach is applied to complete the update of the near-field radiation. …”

Automatic control technology of low frequency and low voltage splitting devices using wide area measurement information by Mingliang GAO, Bo ZHUANG, Xuefei NIU, Mouying LI

“…Aiming at the problems of large noise content of wide area measurement information of power grid and difficulty in controlling oscillation damping in interconnected areas of power grid, an automatic control technology of low frequency and low voltage splitting devices using wide area measurement information was proposed.Based on the wide area measurement system (WAMS), the wide area measurement information of the power grid during the operation was obtained.After the noise contained in the wide area measurement information of the power grid was removed by the wavelet decomposition de-noising method, the power grid low-frequency oscillation identification method based on Prony was used to identify the power grid oscillation region and oscillation value.Then, based on the grid oscillation region and oscillation value, the oscillation center voltage and positioning coefficient were calculated and used as input to design the automatic control flow of the low frequency and low voltage splitting device, so as to realize the automatic control of the low frequency and low voltage splitting device.The experimental results show that this method can effectively remove the noise contained in the wide area measurement information of the power grid, the maximum error of the oscillation damping value in the interconnected area of the power grid is only 0.01, and this method can effectively control the low frequency and low voltage splitting device.…”

Short-hair black holes and the strong cosmic censorship conjecture by Zhiqin Tu, Meirong Tang, Zhaoyi Xu

“…This paper, set against the background of short-hair black holes, explores whether they obey SCCC when subjected to scalar field perturbations. Using the WKB method, Prony method, Lyapunov exponent, and Weak Gravity Conjecture (WGC), the behavior of a short-hair black hole under different parameter conditions was systematically analyzed. …”
