Sequence mining is used to discover patterns in text data, which can improve machine translation, text summarization, and sentiment analysis. Sensor Data Analysis: In IoT and other sensor-based systems, sequence discovery can detect patterns of sensor readings that indicate system states or predict failures.
Orebody shape, access to infrastructure, grade distribution, stress directions and magnitudes all influence the point at which to initiate the mining sequence. Determining the mining sequence, including decisions about which blocks to extract and the timing of their extraction represents the central goal of long-term mine production …

Two mining sequences are considered; bottom-up (B-U) and top-bottom (T-B), and the instability of stopes and open pit slopes is evaluated in response to each sequence. For the present rock mass ...
Mining involves a number of stages which occur in a sequence. This sequence of stages is known as the mining sequence. The mining sequence covers all aspects of mining, including: prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials and, once a mine is closed, the restoration of all …
The task of sequential pattern mining is a data mining task specialized for analyzing sequential data, to discover sequential patterns.
Sequential pattern mining is the mining of fre- quently occurring ordered events or subsequences as patterns. An example of a sequen- tial pattern is "Customers who buy …

Kang simulated different mining sequences in the middle level of the Xinli mining area of Sanshandao Gold Mine, obtaining characteristic values of the stress and displacement of rock under different mining steps. This work suggested that it is safe and efficient to mine one panel at the interval of two panels . Based on the time-varying ...
498 Chapter 8 Mining Stream, Time-Series, and Sequence Data8.3 Mining Sequence Patterns in Transactional Databases A sequence database consists of sequences of ordered elements or events, recorded with or without a concrete notion of time. There are many applications involving sequence data.
Repetitive mining beneath bedding slopes is identified as a critical factor in geomorphic disturbances, especially landslides and surface subsidence. Prior research has largely concentrated on surface deformation in plains due to multi-seam coal mining and the instability of natural bedding slopes, yet the cumulative impact of different mining …
L-tyrosine is a key precursor for synthesis of various functional substances, but the microbial production of L-tyrosine faces huge challenges. The development of new microbial chassis cell and gene resource is especially important for the biosynthesis of L-tyrosine. In this study, the optimal host strain Bacillus amyloliquefaciens HZ-12 was …
2. Litemset Phase. In the paper [], the length of a sequence is the number of itemsets in the sequence.The support for an itemset i is defined as the number of customers who bought the items in i in a single transaction. Thus the itemset i and the 1-sequence (langle irangle) have the same support. An itemset with minimum support …
Sequential pattern mining, also known as GSP (Generalized Sequential Pattern) mining, is a technique used to identify patterns in sequential data. The goal of …
Firstly, the 870–898 m level of the eastern mining area in the Tiaoshuihe phosphate mine was divided into 25 ore blocks, and six different mining sequences were designed for this area.
Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative ways. Mining companies need to integrate environmental and social impact assessments into mining projects.
mining, there are two mining sequences: first mining and then filling or first filling and then mining. The determination of a reasonable mining sequence in controlling surface sub-sidence is an important problem in strip filling mining. In this paper, the west 510 mining area of the Liudong Coal Mine was selected as the engineering background.
Simple sequence repeats (SSRs) or short tandem repeats are short repeat motifs that show high level of length polymorphism due to insertion or deletion mutations of one or more repeat types. Here, we present the detection and abundance of microsatellites or SSRs in nucleotide sequences of Gentianace …
Deep mining of the Sequence Read Archive reveals major genetic innovations in coronaviruses and other nidoviruses of aquatic vertebrates PLoS Pathog. 2024 Apr 22 ... We recovered the bisegmented genome sequences of two coronaviruses from RNA samples of 69 infected fishes and validated the presence of poly(A) tails at …
