A Relationship Between Blue and Near‐IR Global Spectral Reflectance and the Response of Global Average Reflectance to Change in Cloud Cover Observed From EPIC by Guoyong Wen, Alexander Marshak, Wanjuan Song, Yuri Knyazikhin, Matti Mõttus, Dong Wu

“…We found that the vector composed of blue and near‐infrared (NIR) reflectance follows a counterclockwise closed‐loop trajectory from 0 to 24 UTC as Earth rotates. This nonlinear relationship was not observed by any other satellites due to limited spatial or temporal coverage of either low Earth orbit or geostationary satellites. …”

Identifying the Occurrence Time of the Destructive Kahramanmaraş-Gazientep Earthquake of Magnitude <i>M</i>7.8 in Turkey on 6 February 2023 by Nicholas V. Sarlis, Efthimios S. Skordas, Stavros-Richard G. Christopoulos, Panayiotis K. Varotsos

“…The results obtained are in the positive direction pointing to the fact that after 3 February 2023 at 11:05:58 UTC, a strong earthquake was imminent. Natural time analysis also reveals a minimum fluctuation of the order parameter of seismicity almost three and a half months before the <i>M</i>7.8 earthquake, pointing to the initiation of seismic electrical activity. …”

IpDFT-Tuned Estimation Algorithms for PMUs: Overview and Performance Comparison by David Macii, Daniel Belega, Dario Petri

“…However, the basic IpDFT algorithm can be used also as a preliminary estimator of the amplitude, phase, frequency and rate of change of frequency of voltage or current AC waveforms at times synchronized to the Universal Coordinated Time (UTC). Indeed, another cascaded algorithm can be used to refine the waveform parameters estimation. …”

Precursor Analysis Associated With the Ecuador Earthquake Using Swarm A and C Satellite Magnetic Data Based on PCA by Kaiguang Zhu, Kaiyan Li, Mengxuan Fan, Chengquan Chi, Zining Yu

“…A large magnitude 7.8 earthquakes occurred in Ecuador at 23:58:36 Coordinated Universal Time (UTC) on April 16, 2016. In this paper, we revisit this earthquake by simultaneously analyzing the magnetic field data of Swarm satellite A and satellite C based on principal component analysis (PCA), and the eigenvalues and principal components are calculated throughout 2016. …”

An observational study of the inner core structure of Typhoon Meranti (2016) near landfall by Xiping Zhang, Jie Tang, Chenfeng Wu, Dan Wu

“…As Meranti was very close to Taiwan's southern tip when passing by, its deep convection distribution, especially part on the down motion right side, was impaired by the topography of Central Mountain Range, thus contributed to this asymmetry. The eyewall at 1645 UTC was examined in detail, and it was found that the primary circulation with weaker azimuth perturbations remained intact at this time, while vertical circulation differed with direction. …”

Implementation of Phasor Measurement Unit Based on Phase-Locked Loop Techniques: A Comprehensive Review by Vasilis Giotopoulos, Georgios Korres

“…PMUs can measure bus voltage and branch current phasors of a three-phase network, as well as the frequency and the rate of change of frequency (ROCOF), with high speed, accuracy and time stamping provided by global positioning system (GPS) at the coordinated universal time (UTC). Various phasor estimation algorithms have been proposed in the literature, while most of them are concentrated in the discrete Fourier transform (DFT) algorithm, where an integer number of samples multiple of the nominal frequency is required for the computations. …”

Método de algoritmo de clúster para el análisis del perfil de investigadores científicos by Gustavo Rodríguez Bárcenas

“…La aplicación del procedimiento en el Centro de Estudios de la Energía y Tecnología Avanzada de Cuba (CEETAM) y la Universidad Técnica de Cotopaxi (UTC) en Ecuador, evidenció su efectividad. Como resultado se pudo identificar los profesionales con mayores niveles de coincidencia en áreas a fines y líneas de investigación, lo que propicia el establecimiento de Comunidades Colectivas de Conocimientos; se pudo demostrar que los métodos empleados pueden ser integrados a las TIC, resultando en la obtención de relaciones perceptuales entre los investigadores y expresando los grupos que se forman a partir de conglomerados de observaciones en cada subcategoría y dominios de conocimientos de los dos casos de estudio analizados. …”
