Grundlagen der Betriebswirtschaftslehreis paper studies the processing method of acoustic emission signal based on the active excitation signal of shale surface and the data output from hydraulic fracturing test. Event detection is the preliminary signal processing, to obtain the event information conveyed by acoustic emission signal and

Grundlagen der Betriebswirtschaftslehrealways exist in model updating due to incomplete information in measurement and modeling. These uncertainties usually cause the problem of non-uniqueness, i.e., multiple equivalent models can fit the experimental data the same well. Locating all these equivalent models and including them for represe

Grundlagen der Betriebswirtschaftslehree materials in ocean engineering need to be resolved urgently. In this paper, aiming at the concrete erosion caused by sulfate in marine environment, the evolution analysis of the expansion stress of the erosion products is carried out based on the principles of thermodynamics and crystallography.
