Abstract: The new logging data of Daqing Oilfield every year is still scattered stored on a computer system in a separate document form at present, everytime use these logs are required to achieve through remote transmission,it’s very inconvenient and low retrieval efficiency. In view of this situation, we developed oilfields log digitizing system, establish a specialized database for Daqing Oilfield logs.It can achieve the logging data collection, processing, storage. With the computer database technology , network technology, it fundamentally reduce the manual statistics workload of reservoir evaluation personnel .

Abstract: Network Security Logs are the records of the important activities and changes of the network, which not only records the state changes of network or mainframe at any time, but also provides the data bases for the network administrators to conduct network management. How to obtain the effective information of security events from the logs with different formats, thus realizing the detection, analysis and evaluation of the security events, has always been the key point to improve the important content of information security protection and focused on by the network administrators. The paper presents a kind of descriptive language of computer network security focusing on the log management, which realizes the uniform description of the common logs in the network with its effectiveness being verified in the actual network environment. It provides the infrastructural support to improve the early warning capacity towards the information security events.

Abstract: The testing experiments to healthy larch logs samplings whose diameter scopes are in 5-12cm and the length respectively are 10cm and 30cm were conducted by using Arbotom stress wave testing instrument and universal mechanics testing machine. The relationships between dynamic modulus of elasticity of stress wave and MOE, between MOR and MOE were all studied in the larch logs samplings. The results indicated that, in the two larch logs samplings, the dynamic modulus of elasticity of stress wave had positive linear correlation with MOE. Moreover, MOR also had a good linear correlation with MOE.

Abstract: The testing experiments to healthy poplar and larch logs samplings were conducted by using hydraulic machine. The relationships among compression and bending strength, modulus of elasticity in compression and bending were studied in the two logs samplings. The results indicated that, in the both species, the compression strength had certain linear correlation with bending strength, and so did the modulus of elasticity in compression and bending. Meanwhile there were remarkable linear correlations with the compression strength and the modulus of elasticity in compression as well as the bending strength and the modulus of elasticity in bending.

Abstract: This paper presents a security protection model of logs from the aspect of the system security architecture and technical feasibility, describes complete system architecture according to the system design objects, and gives the design process of each module in this system. Finally the proposed algorithm for association rules mining is experimentally tested in the network security audit system and there are satisfactory results.
