The rope of the lane rope is placed in a first semicircular fixing hole of the first casing and a second semicircular fixing hole of the second casing, and then the first casing and the second casing are coupled to each other so that the rope of the lane rope is surrounded by the cylindrical body to complete the assembly.

Abstract: A system, method, and apparatus are provided for identifying clients or consumers of one or more controlled resources within a computing environment (e.g., a data center, a computing cluster). The resources may be controlled via the enforcement of quotas, wherein different clients have different quotas for the controlled resource(s). A client associated with a given call to a resource is identified using a tuple formed from identifiers of multiple services in the call stack, such as a first service (e.g., a front-end or user-facing service) and an immediate service (e.g., a final service in the stack prior to receipt of the call at a gateway, broker, or other entity that manages access to the controlled resources).

Abstract: Systems and methods according to aspects of the invention verify requests for information over a network. Computing devices communicating over a network transmit numerous signals with various types of information including spatial information, temporal information, device-specific information, and transmission specific information. This information may be used to generate statistical records of valid request for information. Various combinations of these signals may be used to determine whether a request for information is a valid request based on the statistical records associated with the signals. Where a request for information has been verified, the system and method may provide the information. Where the request for information has not been verified, the system and method may deny the request for information. Thus the system and method may be used to prevent and block scraping and spamming attacks.

Abstract: A method for continuous thin strip casting comprises: introducing molten steel through a long nozzle into a tundish from a ladle, the tundish is one strand tundish, and the molten steel flows below a weir, then passes a first dam and enters a channel with an induction heating device, and the heated molten steel then flows out from an outlet at the other side of the tundish to a nozzle also with an induction heating device for casting. The distances between the weirs of the tundish and the channel have optimal distance ranges. The present invention can improve the casting stability and the quality of the casting strip.

Abstract: A system, method, and apparatus are provided for visualizing quotas on resources within a computing environment (e.g., a data center, a computing cluster) that includes multiple brokers, gateway servers, or other entities that control access to the resource(s). Through a visualization interface, an operator of a quota system can set, change, and/or delete quotas on resources and/or sub-resources for any number of clients or consumers of the resources. The visualization interface may also enable access to a log of changes to quotas and/or graphs or other displays of statuses of any selected quotas for any selected clients and resources/sub-resources.

Abstract: A system, method, and apparatus are provided for locally enforcing quotas on resources within a computing environment (e.g., a data center, a computing cluster) that includes multiple brokers, gateway servers, or other entities that control access to the resource(s). Instead of using global access statistics provided by all gateways, each server individually allows or denies requested access to a resource based on whether the requesting client has already exceeded its quota (or would exceed its quota if the request is approved). A client associated with a given call to a resource may be identified using a tuple formed from identifiers of multiple services in the call stack, such as a first service (e.g., a front-end or user-facing service) and an immediate service (e.g., a final service in the stack prior to receipt of the call at a gateway, broker, or other entity that manages access to the controlled resources).

Abstract: A computer program product has a computer-readable storage medium having computer program instructions embodied therein for performing a method for implementing a privacy policy for a user. The method may include the user developing rules that determine whether another user (requester) can access information related to the user. The rules may be stored in a database coupled to a server and evaluated when a request is received from the requester to access the information. If a rule is satisfied by the requester, the server can return the information to the requester. The information can be returned at a level of granularity specified by the user in the satisfied rule. A privacy level can be set by the user to allow access to requesters based on the rules or to deny access to any requesters.
