Increasing the Reliability of Flood Embankments with Neural Imaging Method

Abstract

Featured Application: The proposed neural imaging method helps improve the functionality of widely used tomographic methods. The presented method is suitable to monitor the protections of the tailings ponds and flood embankments.Abstract: This paper presents an innovative system of many artificial neural networks that enables the tomographic reconstruction of the internal structure of a flood embankment. An advantage of the proposed method is that it allows us to obtain high-resolution images, which essentially contributes to early, precise and reliable prediction of operational hazards. The method consists in training a cluster of separate neural networks, each of which generates a single point of the output image. The simultaneous and parallel application of the set of neural networks led to effective reconstruction of the internal structure of a deposition site for floatation tailings. Results obtained from the study allow us to solve the low resolution problem that usually occurs with non-invasive imaging methods. This effect was possible thanks to the design of a new intelligent image reconstruction system.

Effect of technological parameters on vibration acceleration in milling and vibration prediction with artificial neural networks

“…Similarly to the analysis of the cutting force components [23], it is on axis x that the analysed indicator of machinability reaches the highest magnitude, which is the reason for the selection of the particular component and axis. Vibration components in milling were modelled with the application of artificial neural networks [24] by means of Statistica Neural Networks software. Two network types were employed in the study: MLP (Multi-Layered Perceptron) and RBF (Radial Basis Function).…”

Comparison of Selected Machine Learning Algorithms for Industrial Electrical Tomography

“…Sensor technologies are mainly based on electrical tomography (ET) [34,35,36,37,38], which includes electrical capacitance tomography (ECT) [39,40,41,42,43,44,45] and electrical resistance tomography (ERT) [7,46,47]. It allows reconstruction of the image by the distribution of conductivity or permittivity of the object from electrical measurements at the edge of the object.…”

Flood Mitigation Using an Innovative Flood Control Scheme in a Large Lake: Dongting Lake, China

“…Flood disaster causes the greatest losses among natural hazards and it has become more severe and most frequent in recent years due to climate change, urbanization, and water infrastructures. [1][2][3]. Economic losses from flood hazards have considerably increased over the recent decades [4].…”

“…For example, there are two dams with a flood control capacity of 1.97 billion m 3 in the Brisbane River catchment, but Brisbane city on the river delta was flooded twice in the 20 th century, and the city was flooded again, leading to 35 deaths and $2.55 billion economic loss in 2011 [7]. The TGD is one of the largest dams in the world, with a flood control capacity of 22.1 billion m 3 , but it only controls 56% of the Yangtze River catchment area (see the shadowed area in Figure 1); floodwater from the downstream area cannot be controlled, even where the mega-cities, like Wuhan, Nanjing, and Shanghai, are situated. When the floods come from the middle or lower part of the Yangtze River basin, the TGD cannot effectively regulate the floodwater for the purpose of disaster mitigation, as happened in Brisbane in 2011.…”

“…In this paper, the feasibility study of applying the new flood control scheme (IFCS) to the Dongting Lake was conducted while using the hydrodynamic module of MIKE 21 FM (flow model) with a long-time simulation (June to September 1998). The main objectives were to: (1) investigate the flooding process in Dongting Lake; (2) apply and design the IFCS into Dongting Lake; and, (3) examine its feasibility for the flood mitigation in Dongting Lake and its downstream region. This is the first attempt to investigate the application of the IFCS in Dongting Lake while using MIKE 21 FM.…”
