A fully revised second edition of the best guide to high-frequency trading. High-frequency trading is a difficult, but profitable, endeavor that can generate stable profits in various market conditions. But solid footing in both the theory and practice of this discipline are essential to success.
Jan 20, 2019 1 FOREWORD. The main feature of waferlevel packaging of MEMS (micro electromechanical system) is hermetic or vacuum sealing while retaining internal space. 1 With highfrequency (RF) MEMS switches, internal space is usually retained in vacuum to prevent degradation of electric contacts, or to maintain switching speed through suppression of aid damping. 2

Jun 10, 2019 Highfrequency band ultrasonic waves emitted from the spark discharger cannot be accurately measured. This is because the upper limit of the frequency band of commercially available microphones only reaches around 200 kHz, 7 and ultrasonic waves in bands exceeding 200 kHz cannot be accurately evaluated using such microphones.

Deep low-frequency earthquakes (LFEs) are known to occur in dehydration phenomena from the subducting hydrous slab and in magmatic phenomena beneath Quaternary volcanoes in Japan. To realize the spatial and temporal characteristics of the magmatic deep low-frequency earthquakes, their hypocenters along with those of ordinary overhead high-frequency earthquakes are analyzed
Japan. By scrutinizing high-frequency signals, we detect 5 times as many aftershocks in the first 200 s as in the Japan Meteorological Agency catalogue. After correcting for the changing completeness level immediately after the main shock, the aftershock rate shows a crossover from a slower decay with an Omoris law exponent p 0.58 0.08

We studied the scattering properties of high-frequency seismic waves due to the distribution of small-scale velocity fluctuations in the crust and upper mantle beneath Japan based on an analysis of three-component short-period seismograms and comparison with finite difference method (FDM) simulation of seismic wave propagation using various stochastic random velocity fluctuation models. Using ...

Nov 16, 2020 The annual output of heavy placer gold in the gold ore dressing plant accounts for about 25% of the annual gold output. When the coarse-grained gold enters the leaching system, the process flow cannot be satisfied due to the long leaching time required, which further affects the tailings and tailing liquid indicators.

Deep low-frequency earthquakes (LFEs) are known to occur in dehydration phenomena from the subducting hydrous slab and in magmatic phenomena beneath Quaternary volcanoes in Japan. To realize the spatial and temporal characteristics of the magmatic deep low-frequency earthquakes, their hypocenters along with those of ordinary overhead high-frequency earthquakes are analyzed
Feb 02, 2021 Distinct later phases of waves with rich high-frequency ( 8 Hz) components were observed for intraslab earthquakes that occurred at intermediate depths, particularly at depths exceeding 100 km, in the northeastern (NE) Japan subduction zone. These high-frequency later phases (HFLPs) showed anomalously large peak-amplitude delays, up to 50 s after direct S-wave arrivals at stations

Incoherency of high-frequency seismic waves leads to the idea to analyze seismogram envelopes disregarding phase information for the source study. We develop an inversion method for estimating high-frequency (above 1 Hz) energy radiation from the earthquake fault and site amplification factors from observed mean square S-wave seismogram envelopes, The inversion is executed by using the s
