Fig. 2 Intrusion Tolerance Model with Autonomic Feedback Mechanism Preprocessing of Input Data.
With the operation of the system, data in the knowledge base will increase and Server can process the suspicious information more rapidly.
A total of 2,000 records are taken from the KDDcup 99 data set as the training set.
The training results are showed in Fig. 4, in which, the first 1,088 records are normal ones with an expected output of 0.99 while the others are attack data with an expected output of 0.01.
Make N represents normal data records, A abnormal data records, G the attack information that is determined, Y the suspicious information that is determined, X the reliable information that is determined, and is the proportion of normal data determined as attack information.

In protocol stack, media access control (MAC) protocol is located in data link layer.
Lightweight medium access control (LMAC) divides time into slots with a fixed frame consisting of control part and data part [6].
A node always starts by sending out control packet even if it does not have any data to send.
The length of slot is assigned according to traffic and distance for the reduction of energy consumption.
Cross-layer scheme may be proposed by exploiting control/data exchange between nodes.

A conceptual scheme for generation of alternative process plans in the form of a network is developed, based on part design data modeling in terms of machining features.
This in turn may yield more efficient utilization of machine resources, correspondingly to reductions in manufacturing cycle times.

Data model for CAPP.
Subsequent features are established by searching data matrices until the need for a new setup occurs.

The obtained results of simulations are in good agreement with experimental data. 1.
Therefore, an ARAMIS digital image correlation (DIC) system was used to obtain the full-field in-plane displacement and strain data.
The empty regions in the picture represent the flaking of paint, which was speckled, and thus the data at these regions was not collected.
The material’s elasto-plastic behaviour was defined by inputting the true stress-strain data obtained from the nominal stress-strain test data for both types of specimens.
If mechanical gauges were used, these data had required several tests with different gauges.

Each IDS client can monitor and capture the data packet passing through the neighbor nodes.
This algorithm will firstly find the suspected nodes in the list through checking the data consistency.
Wormhole attack can destroy the data packet of the routing and network of the WSN, which will lead to the reduction of location accuracy and communication quality of WSN.
(3) Resource exhaustion attack means that there will be conflicts between the data packets the attackers send constantly to the network and the data packets sent by the normal nodes.
The acquiescent defense mechanism will allow the sending nodes to send the data packet again.

New data on structure and texture features of Cu and Ti rods, subjected to ECAP at 20oC and 400 oC respectively, were obtained by means of advanced X-ray diffractometric methods.
Introduction Though structure and texture formation under equal-channel angular pressing (ECAP) is now the main topic of numerous studies, still a number of questions remains to be considered more accurately on the basis of additional experimental data.
According to presented data, elastic microstrain Fd/dav at least by 5 times exceeds maximal values of lattice distortion g, being equal to - 0.50% and 0.10%, respectively
This conclusion, based on experimental data, agree with the simulated deformation field [6], where elongated cells within top and bottom regions of the cross-section are tilted relative to axis X by different angles.
It is evident from texture data, that the most disordered deformation process and the turbulent plastic flow take place within B-region.

The transient response results were compared with measurement data under the practical application to verify reliability and equivalence of the constructed CAE model.
The experimental measurement data is also presented to validate the simulated results in this paper.
The simulated frequency spectrum shows well coincident to the practical data.
The harmonic frequencies of gear pair II, 213.83 Hz, 427.57 Hz, 640.88 Hz and 849.64 Hz, can also be seen in the frequency spectrum which is coincident with the practical measurement data.

Data modelling is an ill-posed problem where the underlying distribution of the data to be modelled is unknown.
This means that the structure and the parameters are not predefined (e.g. number of processing elements, number of layers etc.) but they are data driven in such a way that the capacity of the model will match the complexity of the data.
By choosing the appropriate value for C it is possible to avoid over-fitting the training data and at the same time getting a model with sufficient capacity to satisfactorily describe the data.
The Kernel function projects the data to a high dimensional space.
In the case study of wound-core transformers, 1950 sets of test data were separated into 30 subsets of 65 data sets each (29 subsets for training and 1 subset for validation).

The statistical data showed that during 1950-90s’, the average precipitation decreased by decade in most of stations (table 1).
According to the groundwater exploitation data from 1985 to 1995, the excess development of the low groundwater was 15.6×108 m3/a; and the deep groundwater was 8.9×108 m3/a.
According to data, the bigger funnels were Shijiazhuang, Jizaoheng and Cangzhou[3] (table 3).
According to the pertinent data, above 70% of total precipitation in Hebei plain approximately all transforms as soil water, another small part turns to the deep aquifer, and transforms as the ground water.
According to the data from Hebei Bureau of Water Resources, in 1950s’, surface runoff of the whole province was 199×108 m3/a and water which goes into the sea was 86.4×108 m3/a; in 1980s’, surface runoff of the whole province was 81.3×108 m3/a, and water into the sea was 13.2×108 m3/a.

An analysis of experimental data using a kinetic model yields the diffusivity of solute in the Cu matrix, which is in agreement with the reported diffusivity of Ni in Cu.
The alloy ingots were homogenized at 900 oC for 24 h in a vacuum and then cold-rolled to 50% reduction in thickness.
A kinetic analysis of experimental data using the growth model by Chen et al. [10] shows that the thickening of g disks is controlled by the Ni diffusion in the Cu matrix.
