Environmental factors that can affect the settlement rate of quagga mussel veligers include flow velocity, water temperature, pH, dissolved oxygen (DO), conductivity, total organic carbon (TOC), and the surface roughness of monitoring substrates. In the present study, six artificial substrates, Acrylonitrile Butadiene Styrene (ABS) plastic, High Density Polyethylene (HDPE) plastic, Concrete Und...

Leachate recirculation (LR) in municipal solid waste (MSW) landfills operated as bioreactors offers significant economic and environmental benefits. The subsurface application method of vertical wells is one of the most common LR techniques. The objective of this study was to develop a novel two-dimensional model of leachate recirculation using vertical wells. This novel method can describe lea...

The interaction influence on subway tunnels adjacent to foundation excavation was produced by excavation construction, and it is great significance for the correct assessment of its size and influence on the safety of subway operation. Based on the foundation excavation project, some typical foundation excavation profiles are selected, the calculation and analysis on additional settlement and h...

In the context of quality assurance for the emergency medical services in Bavaria a segmentation of the municipal areas is necessary. Such municipal subareas are not officially defined; however, official submunicipalities do exist as point information. On the basis of these points an algorithm, generating reasonable borders within the municipal areas, was developed and implemented using ArcPy. ...

ABSTRACT: This paper presents a neural network based approach to disseminating information relating to experimental and field observations in engineering. Although the methodology is generic and can be applied to many areas of engineering science, attention is focussed here solely on geotechnical engineering applications. Field data relating to the settlement of foundations presented by Burland...

The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can...
