Abstract: A data merging method for distributed computing uses a configuration file to guide the insertion of computational results obtained by distributed nodes into a database table, and to merge the computational results inserted in the database table. The configuration file is established according to the task splitting conditions of distributed computing. The method uses a data merging server to import and host the configuration file and create a database table corresponding to the configuration file. Each distributed node inserting its distributed computational result into the database table after completing the respective distributed computing task, while the data merging server merges the data in the database table. An interface standard applicable to various uses and various distributed computing tasks may be used such that the user only needs to establish a job-specific configuration file based on the interface standard.

Abstract: Disclosed are methods for increasing microbial catalase production. 1-10 g/L sodium hexametaphosphate was added to the culture medium between 30-40 hours of fermentation to inhibit proteinase activity and increase the production of catalase. This simple modification of fermentation procedure can result in up to 45% increase of the production of catalase.

Abstract: A method for scouring and bleaching cotton fabric with composite enzyme preparation in one bath is provided. The method relates to the application of composite alkaline enzyme preparation in scouring and bleaching processes of cotton fabric. The enzyme preparation for scouring and bleaching cotton fabric is compounded from cutinase, alkaline pectase, alkaline xylanase, alkaline cellulose, and carbohydrate oxidase. The method includes: scouring the cotton fabric by adding the composite enzyme preparation, glucose, oxidation bleaching stabilizer RB-3, penetrant JFC, and Triton X-100 in a treating bath at 55-70° C. and pH 8-10, and then bleaching the cotton fabric for 30 min by directly adding tetraacetyl ethylenediamine (TAED) in the scouring bath to activate hydrogen peroxide. After being treated by the method of the present invention, the cotton fabric has high impurity removal ratio, favorable wettability, and high whiteness.

Abstract: The present invention discloses a method and a system for log file analysis based on distributed computing network. The method includes: storing user identifiers and related log information into a log file; dividing the log file into target files each including the log information having the same user identifier; separately analyzing the target files to obtain analysis results using at least two nodes; and combining the analysis results of the nodes. The method thereby establishes relationships among various log files through user identifiers, and further analyzes the relationships among the user's accesses to various contents of a website.
