For storage and recovery requirements on large-scale seismic waveform data of the National Earthquake Data Backup Center (NEDBC), a distributed cluster processing model based Kafka message queues is designed to optimize inbound efficiency stored in HBase at NEDBC. Firstly, compare characteristics big architectures with that traditional disk array architectures. Secondly, realize analysis periodic truncation, write NoSQL record form through Spark Streaming cluster. Finally, test read/write...
In order to cope with the problems of high frequency and multiple causes mountain fires, it is very important adopt appropriate technologies monitor warn fires through a few surface parameters. At same time, existing mobile terminal equipment insufficient in image processing storage capacity, energy consumption data transmission process, which requires calculation unloading. For this circumstance, first, hierarchical discriminant analysis algorithm based on feature extraction introduced,...
An earthquake emergency command system is designed based on cloud computing and the Internet of Things (IoT) to mitigate slow information acquisition, low processing efficiency, weak storage communication ability in rescue. First, technology introduced, a traditional analyzed comprehensively. Then, characteristics midwave infrared remote sensing data are explored before after recent earthquakes China satellite data. Subsequently, new built IoT along with from sensing. Finally, feasibility...
For the mosaicking of multiple remote sensing images, obtaining optimal stitching line in overlapping region is a key step creating seamless mosaic image. However, for very large computation finding seamlines involves huge amount image pixels. To handle this issue, we propose stepwise strategy to obtain pixel-level lines images via an upscaling–downscaling sampling procedure. First, resolution reduced and graph cut algorithm applied find energy-optimal seamline Then, stripe along preliminary...
In view of the shortcomings traditional manual means GPS field mapping data in earthquake field, quality management is inefficient. This paper develops original platform based on desktop virtual observation management, reporting, and archiving. Based research content this paper, a set seismic system software virtualization was designed developed to solve inconvenience caused by complex operation process service. The results will effectively improve efficiency measurement inspection.
Abstract Highly similar waveforms recorded from repeating earthquakes can be utilized to evaluate the data quality of a seismic station. We used hypothesis testing method establish detection model based on earthquakes. The effectiveness was verified by using pair earthquakes, which occurred in northeastern Japan 20 March 2021 (Mw=7.0) and 1 May (Mw=6.9), 109 stations Global Seismographic Network. A total 842 permanent broadband mainland China were evaluated this model. Eighteen anomalies...
