As a result, the reduction of allowable stress or allowable defect size due to misalignment is exaggerated by the use of the formula for unrestrained flat plates [2,3].
Note also that the reduction of the net cross-sectional area due to the growth of the notch from ductile tearing did not prevent remote yielding from occurring.
More data or analysis is needed to confirm whether a 20% level of misalignment is generally acceptable.

Analytical solution along basic dimension is apparently preferable in all aspects for qualitative analysis of calculation data.
The reduction of the initial boundary problem to multipoint boundary problem for the first-order system of ordinary differential equations with operational coefficients by separation of derivatives with respect to the basic dimension.
The reduction (after introduction of additional unknowns) of the considering problem to resulting multipoint boundary problem for the first-order system of ordinary differential equations with piecewise-constant coefficients.

The model is verified using experimental data; it indicates that the neural network model has a good effect on the forecast of the diagonal crack widths.
However, the artificial neural network served as non-linear statistical data modeling tools, they is often used to model the complex relationships between inputs and outputs or to find patterns in data.
Before carrying on the network training, it needed to normalized data.
This paper adopted 0-1 data matrix method, the training value was reduced as ratio of input value to the maximum input value.
The result is that the output value agreed with the experimental data.

The theoretical results are in agreement with experimental data.
The theoretical results are found to be in good agreement with experimental data.
For MSMA, according to experimental data, we take
In Fig.3, the solid curves got from the above model and the dash curves from experimental data are for fixed axial field, variable transverse field, while the dot curves from the present model and the dash-dot curves from experimental data are for fixed transverse field, variable axial field.
The theoretical results are found to be in general agreement with experimental data.

Based on the investigate data of Wenchuan earthquake and other previous seismic data, the typical damage of brick-timber structures are summarized and the earthquake resistant design methods and research status are discussed, the earthquake resistant capability of brick-timber structure are also analyzed.
The data show that more than 99% of destructive earthquakes occurred in rural areas in the last 20 years in China [1].
A large number of buildings damaged in this earthquake and provides us valuable data.
We make an overall investigation on brick-timber structures in different seismic regions and analysis their typical damage combining previous damage data.
By now, the research is mainly based on the seismic survey and shaking-table-test data.

The authors conclude that the samples obtained from the fuel element industry can be melting in a VAR furnace, modified to accommodate low density electrodes, allowing a reduction up to 40 times the original storage volume, however, it is necessary to remelt the ingots to correct their composition in order to recycle the original zirconium alloys chips. in a process to reduce volume and allow the reutilization of valuable Zircaloy scraps.
The tendency curve plotted on the experimental data allows the authors to estimate an increase in the apparent density up to 1544 kg/m3 to 300 kN compressing load.
The consolidation process of the zirconium alloy chips by melting in the VAR furnace would allow a 40-fold reduction in the inventory of INB chips, reducing environmental risks as well pyrophoric accidents.

Furthermore, a study by Marchetti et al. [29] reported that a bucket handle tear (50 mm) led to a substantial rise in CP (121%) and a significant reduction in CA (53%).
For example, an experimental study found that 50% radial tear causes a greater reduction in the strain (4.67-2%) in the anterior portion and a marginal increase in strain in the posterior portion (2-2.5%), while 100% radial tear resulted in the total loss of functionality of the meniscus [28].
For example, an experimental study reported that 100% radial tear in the posterior horn of LM causes a 50% rise in CP and a 47% reduction in CA relative to that of the intact knee joint [43].

Faults occurrence is inevitable in real world and a practical alternative approach is the reduction of fault consequences.
In [24] a prototype of the holonic supervisory control and data acquisition (HSCADA) is presented and applied for IB, and according authors, it has the characteristics of flexibility, scalability, reconfiguration and integration.
It is based on predefined priorities such as: reduction of the performance, shorter recovery time, etc., and on historical data, from where it is possible to measure the statistical significance of each type of fault in terms of frequency rate, recovery time, and operational cost.
The last phase is the “learning phase”, which involves the storage of relevant data for use in further cases.
