The system identification of concrete dams using seismic monitoring data can reveal the practical dynamic properties structures during earthquakes and provide valuable information for analysis structural response, finite element model calibration, assessment postearthquake damage. In this investigation, Pacoima arch dam were used to identify modal parameters. identified parameters dam, derived ...

Habitat fragmentation is the primary cause of the loss of biodiversity and ecosystem services, but its underlying processes and mechanisms remain poorly understood. Studies of islands and insular terrestrial habitats are essential for improving our understanding of habitat fragmentation. We argue that the Three-Gorges Dam, the largest that humans have ever created, presents a unique grand-scale...

At present, the analysis of monitoring data for stress dam is mostly based on statistical models. However, some arch dams have considerably large error, it hard to build a reasonable statistic model data. In order solve practical application problem project, this paper calculates elastic modulus by using finite element displacement hydraulic component separated from horizontal displacement. The...

Machine learning has become increasingly popular for modeling dam behavior due to its ability capture complex relationships between input parameters and responses. However, the use of sophisticated machine methods monitoring behaviors making decisions is often hindered by model uncertainty a lack interpretability. This paper introduces novel health monitoring, focused on radial displacement see...

PURPOSE To evaluate the performance of reconstructed tissue-engineered human corneal endothelium (TE-HCE) by corneal transplantation in cat models. METHODS TE-HCE reconstruction was performed by culturing 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI)-labeled monoclonal HCE cells on denuded amniotic membranes (dAMs) in 20% fetal bovine serum-containing Dulbecco's Mod...

The restorative potential of dam removal on ecosystem function depends on the reversibility of dam effects and its operations. While dam removal is an established engineering practice, the need for an understanding of the ecological response remains. We used paleoflood hydrology, hydrologic modeling, and aerial photo interpretation to investigate the long-term ecologic responses to dam failure ...

DNA adenine methyltransferase (Dam) plays an important role in physiological processes of Gram-negative bacteria such as mismatch repair and replication. In addition, Dam regulates the expression of virulence genes in various species. The authors cloned the dam gene of Yersinia enterocolitica and showed that Dam is essential for viability. Dam overproduction in Y. enterocolitica resulted in an ...

Data-based dam monitoring model can predict behavior and provide scientific basis for risk assessment decision-making of engineering. Traditional safety models established by multiple regression, stepwise gray theory, other statistics-based methods have poor robustness generalization. For this reason, an optimized support-vector machine (SVM) whose novelty lies in simple implementation, self-ad...
