Abstract: A hook comprises an adhesive body and a hook body attached to the adhesive body, where the adhesive body comprises a base layer and an adhesive layer. The adhesive layer is a thermoplastic elastomer with an intrinsic adhesion. The hook body and the adhesive layer are respectively attached to two opposite surfaces of the base layer.

While in use, the adhesive layer isn't directly pulled by the object, thus the adhesive layer has prolonged service life and enhanced adhesive intensity. Besides, through setting the base layer, the hook has better tenacity, and various needed patterns, colors or textures are easily printed on the base layer.

Abstract: A computer software program provides an algorithm that solves for unknown demands (and junction pressures) within a modeling system that uses a generalized, unified loop-node formulation. The program can be used to calculate the available demand (i.e., the amount of water that is to be supplied) according to the nodal pressure. Both nodal heads and flows are simultaneously solved using a gradient algorithm, which allows, in accordance with the present invention, the model to simulate situations where a change in pressure affects the quantity of water used. Criticality analyses for segments of a system in such pressure dependent scenarios can also be performed using the software program of the present invention.

Abstract: The invention proposes a technical scheme for controlling downlink data synchronization in an eMBMS transmission in a radio link control entity in a base station. By determining one length indicator for each service data unit, and meanwhile, each length indicator corresponds to one extension bit, the length indicator and the extension bit of each RLC SDU are byte aligned, and the base station generates different length indicators for the service data units with the different length distribution. By adopting the technical scheme of the invention, the corresponding radio link control header overhead thereof is fixed for each service data unit, and therefore, even in the case where a consecutive packet loss occurs in the service data unit received by a certain base station, synchronization between it and other base stations receiving correctly can still be achieved.
