Cutoff Grade Optimization on Operative Decision Variables with Geological Uncertainty in an Underground Gold Mine: A Real Case Study
Published 2024-11-01“…In order to assess the economic value, we maximize the Net Present Value (NPV), which is carried out by a Genetic Algorithm (GA). This optimization, so-called implicit optimization, generates results of the probabilistic model which are compared with the deterministic one; the results found for a real underground gold mine show that, in the probabilistic case, the Net Present Value is higher and the time horizon is shorter than the results of the deterministic case, and the mining and the processing capacity are higher for the probabilistic case than the deterministic one.…”

Improving Performance of QoS Applications for Wireless Networks
Published 2015-10-01“…In particular, we propose AQEDCA, a traffic-aware minimum contention window adjustment algorithm. We validate our scheme by the extensive real world network tests and the results show that our scheme improves the downlink goodput up to 199.13%, decreases the latency up to 54.77%, and can achieve tight QoS guarantees as compared to the existing schemes.…”

Optimized recovery method of wave field characteristics of tunnel drilling source of drilling jumbo and its engineering application
Published 2025-07-01“…Abstract This study addresses the significant issue of wavefield mixing in seismic data acquired from tunnel drilling jumbo during urban tunnel construction. This paper compares and analyzes the effect of time-domain cross-correlation in the wavelet transform domain through simulation, and concludes that the combination of the time–frequency cross-correlation in the wavelet transform domain, which excels in noise suppression and in the ability of extracting related information, and the algorithm of spike deconvolution. …”
