Estimation on Audibility of Large Cetaceans for Improvement of the Under Water Speaker [PDF]
TransNav, 2012 In order to avoid collisions between the hydrofoil (HF) and cetaceans, the Under Water Speaker (UWS) has been installed on the HF. Because of its potential in utility, we tried to improve the UWS to minimize the risk of the collisions. Under our project,

Clinical Advances in Periodontics, EarlyView.Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.

Nonlinear permuted Granger causality
Canadian Journal of Statistics, EarlyView.Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.

The Sonar Model for Humpback Whale Song Revised
Frontiers in Psychology, 2018 Why do humpback whales sing? This paper considers the hypothesis that humpback whales may use song for long range sonar. Given the vocal and social behavior of humpback whales, in several cases it is not apparent how they monitor the movements of distant

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Frontiers in Marine ScienceThe capture and killing of free-living small cetaceans in the Faroe Islands is described. After being driven on-shore by motor vessels, the animals are killed without pre-stunning using officially-prescribed methods that involve severing the spinal cord ...

Deep Underground Science and Engineering, EarlyView.Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

Deep Underground Science and Engineering, EarlyView.This research proposes an interpretable hybrid stacking ensemble framework, optimized by the Sparrow Search Algorithm, to enhance hard rock pillar stability prediction. By integrating six machine learning models—k‐nearest neighbors, support vector machines, random forests, Gradient Boosting Decision Tree, eXtreme Gradient Boosting, and Light Gradient ...
