A method and device for an inter-RAT handover for a PS service in a dual-mode RNC are disclosed in the present invention, which are used to support an inter-RAT handover optimization flow of the PS service in the dual-mode RNC, thereby solving the problem that the current inter-RAT handover optimization flow does not support the PS handover. With the present invention, in the inter-RAT handover optimization flow, an inter-RAT relocation flow and a radio resource allocation flow of a destination system are executed in parallel, and an encryption indication is sent to a central network through inter-RAT relocation required message; a BSC forwards user data to the central network according to the encryption indication.

The present invention belongs to the technical field of integrated semiconductor circuits, and relates to a method for manufacturing a copper-diffusion barrier layer. In the present invention, a proper reaction precursor has been selected and the atomic layer deposition (ALD) technology has been adopted to develop Co or Ru on a TaN layer to obtain a diffusion barrier layer used in the interconnection for process nodes no more than 32 nm, which overcomes the insufficiency of the PVD deposition Ta/TaN double-layer structure as the copper-diffusion barrier layer in step coverage and conformity, and also effectively solves various serious problems in the Cu/low-k dual damascene process, such as the generation of voids in grooves and through-holes, and electromigration stability.

A method for secondarily synthesizing calcium sulphoaluminate mineral in Portland cement clinker is provided. The method includes adding gypsum into raw Portland cement, calcination, then heating twice to re-form calcium sulphoaluminate mineral that has decomposed at high temperature in the clinker. This method can increase the content of calcium sulphoaluminate mineral in the clinker. As a result, the advantages of the calcium sulphoaluminate mineral in the clinker may be obtained, such as improvement of the early stage performance and long-term performance of the cement clinker and increase in the quantity of mixture in the cement.

A method for selecting a channel for an access point (AP) in a Wireless Local Are Network (WLAN). The method includes the AP receiving network conditions of APs within the sensing range of a terminal sent by the terminal, and the AP selecting a channel based on the received network conditions. By forwarding the network conditions of other APs which can be detected by the terminal, the method of the present invention enables an AP to select a channel from the view of a terminal to avoid conflicts at the terminal, thereby improving the available bandwidth of the terminal, and giving a better experience to users.
摘要:
An asymmetrical IO method and system are described. In one embodiment, a host device includes shared resources for data synchronization of the host device and a client device. The shared resources include a shared phase interpolator. In an embodiment, data lines between the host and client are also used to transmit phase information from the client device to the host device, obviating the need for additional, dedicated lines or pins.

A system and a method for replicating data among heterogeneous databases are disclosed. The system comprises: an initialization module for creating and initializing at least one shared memory, at least one message queue and at least one semaphore in a computer; a source data processing module including a data reader, a data adapter and a data loader; a target data replication module for replicating the data in the shared memory to at least one target database according to the messages in the message queue; and a cleaning module for releasing the shared memory after the replication has been completed. The method comprises the steps of: creating and initializing the shared memory, the message queue and the semaphore in the computer; reading data from at least one source database, then converting the data into target data to be stored in at least one target database, and loading the target data in the shared memory; replicating the target data in the shared memory to the at least one target database according to the messages in the message queue; and releasing the shared memory after the replication has been completed.

A method and device for performing and processing user-defined clipping in object space to reduce the number of computations needed for the clipping operation. The method and device also combine the modelview transformation of the vertex coordinates with projection transform. The user-defined clipping in object space provides a higher performance and less power consumption by avoiding generation of eye coordinates if there is no lighting. The device includes a driver for the user-defined clipping in the object space to perform dual mode user-defined clipping in object space when a lighting function is disabled and in eye space when the lighting function is enabled.

The present invention relates to the preparation of insulinotropic peptides that are synthesized using a solid and solution phase (“hybrid”) approach. Generally, the approach includes synthesizing three different peptide intermediate fragments using solid phase chemistry. Solution phase chemistry is then used to add additional amino acid material to the third fragment which is then coupled to the second fragment and then the first fragment in solution. Alternatively, a different second fragment is coupled to the first fragment in the solid phase. Then, solution phase chemistry is then used to add additional amino acid material to a different third fragment. Subsequently, this different third fragment is coupled to the coupled first and different second fragment in the solution phase. The use of a pseudoproline in one of the fragments eases solid phase synthesis of that fragment and also eases subsequent solution phase coupling of this fragment to the other fragments. The present invention is very useful for forming insulinotropic peptides such as GLP-1(7-36) and its natural and non-natural counterparts.
摘要:
Techniques are described for managing failover in redundant network devices. In particular, each device in a set of redundant network devices includes redundant processing modules. Each module provides a separate operating environment for a set of network services. Each network device includes a control unit that receives configuration information that specifies individual weight values for each of the modules and a threshold value for the network device. The control unit detects failures of the modules and transfers primary responsibility for performing the network service to a second network device when the threshold value is exceeded by a weighted sum of the weight values for the failed modules.
