Warning indicators of the dam body's temperature are required for the real-time monitoring of the service conditions of concrete dams to ensure safety and normal operations. Warnings theories are traditionally targeted at a single point which have limitations, and the scientific warning theories on global behavior of the temperature field are non-existent. In this paper, first, in 3D space, the...

T he last tooth in the dental arch frequently requires treatment of dental caries. Using the rubber dam, dentists encounter difficulty in preparing the distoproximal box because the bow of the clamp interferes with the dental handpiece. This problem has been partly ameliorated by the clamp with a long distal extension. However, in some instances, the extension impinges on the anterior border of...

Temperature is one of the main loads super-high arch dams. (1) Background: a dam in southwest China was taken as an example this paper and temporal-spatial evolution law temperature analyzed based on monitoring data. (2) Methods: finite element simulation analysis method adopted to invert boundary conditions upstream surface thermal parameters concrete, process long-term operation simulated ana...

Evaluation of the sliding stability concrete dams requires use numerical tools not only able to simulate coupled hydromechanical behavior but also adequately represent foundation discontinuities and specific features dam foundations. The formulation a three-dimensional (3D) small displacement finite element model based on interface elements is presented. In this model, hydraulic simulated assum...

The paper describes the first achievements and the future developments of the application of neural networks to structural engineering at ISMES. Two main fields of applications are presented: neural nets in design, with reference to the design of arch dams, and in data interpretation, with reference to the management of structural safety.

A hybrid meta-heuristic optimization method is introduced to efficiently find the optimal shape of concrete gravity dams including dam-water-foundation rock interaction subjected to earthquake loading. The hybrid meta-heuristic optimization method is based on a hybrid of gravitational search algorithm (GSA) and particle swarm optimization (PSO), which is called GSA-PSO. The operation of GSA-PSO...
