EQTransformeris an AI-based earthquake signal detector and phase (P&S) picker based on a deep neural network with an attention mechanism. It has a hierarchical architecture specifically designed for earthquake signals.EQTransformerhas been trained on global seismic data and can perform detection and ...
Sinusoidal signal amplitude and phase control for an adaptive feedback control system In a feedback control system, a reference input element adjusts the amplitude and phase of a sinusoidal component of a command signal applied to the control system to cancel the transfer effects of the feedback...
Signal-enabled or time-based, single-phase, two-phase, or three-phase, grounded or ungrounded fault expand all in page Libraries: Simscape / Electrical / Utilities Description TheFault (Three-Phase)models any permutation of a single-phase, two-phase, or three-phase grounded or ungrounded fault...
Small-Signal Model for Current Mode Control Full-bridge Phase-shifted ZVS Converter In this paper, the small-signal model of a current mode control full-bridge phase-shifted ZVS PWM converter is derived based on the small-signal model of t... X Xu - International Power Electronics & Motion ...
图17 sinusoidal signal with noise or not 可以看到一个幅度为V0的载波和 φn(t) 与V0sinω0t的乘积项,对应于φn(t) 的中心频率的频谱偏移量等于w0。【啥意思?】因此,如果φn的谱在0频附近,输出频谱大致如图2.18所示,可以看到频率自f0处随机偏离。
encoding rewinder because the gradient area on any of the three logical axes must not vary from TR to TR interval or else the spoiling will be spatially dependent. Also, during each TR interval, the received MR signal must be shifted by a phase Φj, so that the k-space data are ...
violation in the phase space of the decays. The data analysed correspond to an integrated luminosity of 5.4 fb−1 collected in proton-proton collisions by the LHCb experiment at a centre-of-mass energy of s = 13 TeV, amounting to approximately 950 thousand and 620 thousand signal candidates...
Mirror M2 is fixed on a piezoelectric transducer (PZT) that is used to enable fine adjustment of the OPD within a 3.5 μm range; the PZT is driven using an amplified triangular wave signal. In the first SHG module, a periodically poled lithium niobate (PPLN) crystal with a length of 5...
An Investigation of Equatorial Ionospheric Irregularities under Solar Maximum in the 24th Solar Cycle in Middle and East Africa Using GPS Ionospheric irregularities exert scintillations on electromagnetic waves when the waves pass through them. So they are interesting for satellite signal propagation in the...
