Cognition Practice in the training process of civil engineering professional talents has a very important role. This paper discusses the present problems in the practice process of civil engineering professional. The functions of multimedia technology and the basic principles followed in the practice process are expounded.
Noise detecting and elimination is important for data acquisition of impact drilling stress wave. ANN (Artificial Neural Network) is provided with stronger fault-tolerance and redundancy. And ANN takes on good robustness for data errors. Therefore, a new method, ANN methods, is put forward on processing ldquoburrrdquo phenomena (noise signal) for data acquisition of impact drilling stress wave. The...
By the analysis of difficulties in VDSM poly gate etching process, firstly, this paper discussed traditional endpoint detection techniques of optical emission spectroscopy (OES) and interferometer endpoint detection (IEP) in detail, then, constructing our innovated endpoint detection system, and based on the complicated signal processing of optical and electrical signal from VDSM poly gate etching...
The feasibility of using the Split Hopkinson Pressure Bar (SHPB) technique to obtain complete dynamic stress-strain curves for rock is established in the laboratory. The SHPB test system, in conjunction with a mean strain hypothesis, can be used not only for obtaining the rock's constitutive curve before the peak strength but also after the peak strength - and so it is possible to analyze and characterize...
