To access the Web server to capture network packets, using the method set of interfaces to capture the data link layer packet, the server process () function to use "SOCK_PACKET" type parameters can be read directly by the data link layer packet Socket, then by the Bind () function enables the socket with the local IP address and port number associated with, and then call listen () and Accept () function so that the process is listening, ready to accept the client's request. 1) Extraction port Port monitor contains a TCP / UDP port for ARP monitoring and surveillance.
Methods to achieve are to extract the port monitor network traffic data port information and information via ARP packet capture module.
The system constantly analyzing to Web server data packet, if in a few seconds required from a fixed visitors packet data connections to the local host different port and number, is considered by the scanning attacks, and take immediate measures. 3) Event analysis Observe the host port connection status does not need to check each data packet associated with the host, only need to extract each session establishing connection and disconnected data packets for analysis on it.
Intrusion analysis on MAC monitoring might be reduced to only analysis to establish the connection of data packets.
Feature Selection of the Intrusion Detection Data based on Particle Swarm Optimization and Neighborhood Reduction [J].

These data are the evidence of the action of corrosion factor in the course of cavitation fracture of oxide-ceramic coatings.
Some prospects for further PEO method development Summarized data of the main properties (thickness and hardness) of PEO coatings on the different alloys are presented in Table 5.
Data comparison clearly indicates the advantages of PEO treatment especially by aluminum alloys.

Through the statistic data we can see that Web has developed into distributed information space.
Galois lattice is its core data structure of the theory of FCA.
So it is very suitable to process data mining from database.
Hence, Galois Lattice is used as an effective tool for data mining and knowledge extracting.
The dimension reduction of the formal context is also one of the future research directions.

The characterisation of the Bauschinger effect and the identification of kinematic hardening models require test setups that are able to generate cyclic stress-strain data.
To receive accurate strain data, an optical strain measurement system ARAMIS (GOM mbh, Braunschweig, Germany) is installed to quantify the local strain data in the 4.0 mm² deformation area of the tension-compression test specimen (fig. 1b) as well as in the 7.5 mm² deformation area of the modified ASTM shear test specimen (fig. 1c).
In contrast to the tension-compression test, this characterisation method needs - resulting from the shear state - an adequate transformation of the raw data for the parameter identification.
Therefore, the kinematic hardening according to Chaboche and Rousselier is identified at two different pre-strains on the basis of data from a tension-compression test and a modified ASTM shear test.
However, the data of tension-compression test and the shear test lead to hardening parameters, which are more or less in a similar order of magnitude.

Hence the collected data can be considered as symptoms and used to assess the reliability and the prognosis of the monitored structure.
They are based on the parameters suggested in the literature [3]; they become the base for the assumptions for the experimental test data.
The statistical models of the actions and resistances are based on existing literature [7] and on the experimental data collected.
Assuming a bi-linear profile [3] [12], from the experimental data it is possible to estimate the deterioration rates (Eq. 5)

It is that the amount of COO groups calculated from the IR and SEM-EDX data increases from 1.463 to 5.307 mmol g-1 with increasing oxidation time from 6 to 48 h.
These results also support the data obtained from FT-IR spectroscopy.
The amount of nitrogen adsorbed on the treated material decreases with increasing concentration of AP which reveals the reduction in the pore volume after the treatment.
The large reduction in the surface area and specific pore volume of the CKT-3 after AP treatment could be attributed to a partial collapse of the whole mesoscopic structure as powder XRD pattern of all the materials shows only a (100) reflection without any higher order peaks.

Some studies indicate significant reductions in surface temperatures could be achieved by spray cooling at low system pressures.
Relevant data shown in Tab. 1 indicate the disproportion between the enhancement of heat flux and heat transfer area.
Heat transfer enhancement on different structured surfaces (data from Wang et al.[4]) Structured surface Fin height (mm) Area enhancement (%) Heat flux enhancement at different volume fluxes (%) 0.044 (m3/m2s) 0.049 (m3/m2s) 0.053 (m3/m2s) Surface 1 0.1 38 39.0 39.5 41.0 Surface 2 0.2 76 53.0 67.0 72.0 Surface 3 0.4 152 31.6 22.0 18.0 In the study of Bostanci et al. [5], the enhancement of heat transfer was attributed to a stronger contribution of phase change mechanisms besides the increase in surface area.
But the scale of cooling capacity enhancement is always smaller than the growth of flow rate resulting in the reduction of spray cooling efficiency.

By means of the collected data, analytical models and two nomograms able to calculate the expected superficial residual stress value, once defined the experimental parameters, were defined.
The main advantage of the first strategy consists of the reduction in the computational time required to perform a simulation.
The use of two different solvers, as here proposed, can furnish a strong reduction of this computational time.
