Abstract: Apparatuses and associated methods of manufacturing are described that provide for an anti-bacterial fiber. The method of manufacturing includes adding a ultra-high molecular weight polyethylene structure into an extrusion device. The method of manufacturing also includes providing an anti-bacterial low-density polyethylene (LDPE) into the ultra-high molecular weight polyethylene at a predetermined temperature to create a combined filament. The method of manufacturing further includes passing the combined filament through a bath. The bath is configured for coagulating the combined filament and extracting a solvent. The method of manufacturing still further includes drying the combined filament via an oven. The method of manufacturing also includes hot-drawing the combined filament. The combined filament is heated during the hot-drawing within the oven and the combined filament generated has anti-bacterial qualities. A corresponding anti-bacterial fiber is also provided.

Abstract: A method for processing a cloud service in a cloud system, wherein the cloud system includes a hosted cloud, an allied cloud, and an alliance management apparatus, wherein the hosted cloud includes a first region, the allied cloud includes a second region, the hosted cloud further provides a virtual region for a user, and the virtual region is mapped by the second region on the hosted cloud. The alliance management apparatus enables a user of the hosted cloud to obtain unified experience when the user accesses the first region and the virtual region in the cloud system, for example, unified experience in control interface access, and unified experience in application programming interface (API) access.

Abstract: A machine learning engine may be used to identify items in a second item category that have a visual appearance similar to the visual appearance of a first item selected from a first item category. Image data and text data associated with a large number of items from different item categories may be processed and used by an association model created by a machine learning engine. The association model may extract item attributes from the image data and text data of the first item. The machine learning engine may determine weights for parameter types, and the weights may calibrate the influence of the respective parameter types on the search results. The association model may be deployed to identify items from different item categories that have a visual appearance similar to the first item. The association model may be updated over time by the machine learning engine as data correlations evolve.

Abstract: A drilling rig includes a base section, a first section, a second section, a third section and a fourth section. For the base section upper region, a fixed pulley block and a guide pulley are installed. Except for the fourth section-crown block section, each section lower region is installed with a lifting lug for a movable pulley block installation for substantially vertical lifting. The crown block section is installed substantially vertical; the subsequent section is located substantially horizontal with the section front pillar upper region connecting to the previous section front pillar lower region. The previous section is substantially vertical lifted to draw the next section skidding into the base section and lifting substantially vertical with the previous section pillar lower region connected to the next section pillar upper region.

Abstract: A computer-implemented method for team battle matching in a computer game is provided. The method includes obtaining registration information and player number information for teams to participate in a team battle having two battle camps and creating a plurality of matching queues. The method also includes allocating teams having equal number of players to a same matching queue based on the player number information and selecting one team from a matching queue allocated with one or more teams having the maximum number of players. Further, the method includes determining whether a total number of players in the selected team is equal to a preset number and allocating the team to a battle camp when the total number of players of the selected team is equal to the preset number.
