The measured data can not be compared with the results by finite element method.
The ultrasonic velocity data indicate that the computed plastic zone, denoted by shaded area shown in Fig. 5(a), is reasonable.
When other αand κof D-P yield criterion is used to model the excavation of the problem, the results deviate more from the measured data than those computed by Eq. (4).

As there are less data for mining, processing and transportation of raw materials and fuel, the construction stage was expressed with relatively accurate life cycle cost.
That is, providing the weighting of various environmental impact types, and then further processing and analyzing the data.
Therefore, the reduction of industrial boiler resource consumption should start with the coal resource.
Economic data in the collected inventory can be classified, non-environmental impact data to internal costs and environmental impact data to external costs.
According to the model and determined data, the external costs in the boiler life cycle were calculated, as shown in Fig. 4.

The main purpose of this study is to provide an ANNs model, knowledge and data on Deuterium–Tritium (D–T) fusion neutron induced damage in MOS devices.
In a second step we arrange the data into training, validation, and test subsets.10% of the data are taken for the validation set, 20% the test set, and 70% training set.
The sets are picked as equally spaced points throughout the original data.
In Figure 4, Note that the data loading is: training base, test base, number of layers and neurons, type of the transfer functions, number of iteration and estimate threshold.

To keep safe operation of power grid, effective harmonic reduction methods must be taken.
Some systems are based on PC associated with off-the-shelf data acquisition component[5,6].
This kinds of system provides abundant memory space for captured data, powerful data processing and analysis ability as well as visual GUI (Graphical User Interface).
The Synchronous Sampling When performing the FFT, all data for the operation is required to be included in a integer cycle, otherwise spectral leakage will occur[8].
The Design of the System Software The software system of the harmonic analyzer mainly includes AC sampling control, FFT, high-precision frequency measurement, parameters computing and data communications.

There is a contradiction between high sensitivity for interference monitoring and reduction of the false alarm probability (Pf).
Measured data from experiments verified the validity of the method.
Too small, single segment is made to have too many data points while too few data segments are get, thus unable to obtain a suitable initial noise spectral density value.
Through the previous analysis, in the algorithm, take K equal to 1/32 of N is suitable, where N is the data points of average windowed periodogram power spectral density.
Transmit the collected interference data to a computer, detect interference from the data, record and analyze the test results.

The most promising way of verifying these experimental research data is computer simulation of structures, also during a fire.
Despite these advancements, there remains a gap in integrating physical damage data with predictive modeling for war-damaged buildings.
The proposed methodology integrates numerical modeling, field observation data, and structural analysis tools to provide a practical framework for post-blast assessment and reconstruction planning.
Methods of Inspection: – Familiarization with the object, available project and technical documentation; – Analysis of initial data; – Conducting visual and instrumental inspections of the building's structural elements, engineering systems, and the object as a whole; – Clarification of operating conditions; – Identification and documentation of existing damage based on the conducted inspection; – Analysis of inspection results and preparation of conclusions with classification of the building according to the specified groups, as well as providing final recommendations for priority and emergency measures.
Experimental and instrumental surveys of the damaged building confirmed the reduction in concrete strength, the disruption of the structure of frame elements, and the need for major repairs or strengthening of several structural components.

However, in the application layer it has only three hosts connecting to transmit data at this time.
As time increases, more and more hosts add to transmit data with the sharing files increasing.
In the last phase as the result of the data transmission reduction, the throughput would be reduced.
In addition the similarity of two graphs is: the real data curve above on the restoration curve, indicating restoration algorithm can not restore the real data completely and need further improvement.

The QoS support such as meeting the data rate and packet delivery time is a requirement in the electric power wireless private network.
Therefore, it is important to find efficient ways of supporting QoS for real-time data in the electric power wireless private network, and efficient data scheduling is one of the ways to address the issue described above.
It’s more fair with the reduction of .
The scheduler will repeat the above process until all resources are allocated or no data in the queue need to be sent.
The above expression can be simplified as: (3) Where, is the user be selected by carrier at time , is the real-time data transmission rate of user on the sub-carrier at time , is the average data transmission rate of user before .
