摘要:
The present invention relates to a method for creating multimedia services comprising: creating a signaling link between the first node and the second node; and the second node negotiating multimedia with the first node via the signaling link to establish a media channel for transmitting stream of the multimedia services and complete creation of the multimedia services at the second node. The present invention also relates to a system for creating multimedia services. Therefore, the present invention allows the signaling link between the first node and the second node to be established and to be used for multimedia negotiation to create the media channel and complete the creation of the multimedia services at the second node so as to implement the unified creation of the multimedia services and simplify the scheduling of the multimedia stream.

The invention relates to a novel kind of chitosan derivative, specifically to quaternized carboxymethyl chitosand derivatives and preparation method. Chitosan with different molecular weight reacts with chloroactic acid give rise to carboxymethyl chitosan. After reaction of Schiff based, deoxidized and quaternized, quaternized carboxymethyl chitosan is obtained. This kind of chitosan derivative have better water-solubility and better antifungal activity, which can used in the fields of medicine and agriculture.

摘要:
A positioning device for a production line of a large and soft infusion bag comprises a driving cylinder (4) and a locating fork (5). The telescoping end of the driving cylinder (4) is connected to one end of the locating fork (5), and the other end of the locating fork (5) is fixed between a soft bag connector nip (2) on the large and soft transfusion bag production line and a filing mouth (1). A stress plate (51) is fixed below the locating fork (5), and located below the soft bag connector nip (2). The device has a simple and compact structure, is inexpensive and reliable to use, and can effectively protect pins, so as to prolong the service life of the pins.
摘要:
A liveness-based memory allocation module operating so that a program thread invoking the memory allocation module is provided with an allocation of memory including a reserve of free heap slots beyond the immediate requirements of the invoking thread. The module receives a parameter representing a thread execution window from an invoking thread; calculates a liveness metric based upon the parameter; calculates a reserve of memory to be passed to the invoking thread based upon the parameter; returns a block of memory corresponding to the calculated reserve of memory. Equations, algorithms, and sampling strategies for calculating liveness metrics are disclosed, as well as a method for adaptive control of the module to achieve a balance between memory efficiency and potential contention as specified by a single control parameter.
