摘要:
In a plate for adjusting a temperature of a substrate, a body of the plate supports the substrate. A first channel and a second channel are disposed within the body of the plate. The first channel has a first inlet and a first outlet and passes therethrough a first fluid to adjust the temperature of the substrate. The second channel has a second inlet adjacent to the first outlet and a second outlet adjacent to the first inlet and passes therethrough a second fluid to adjust the temperature of the substrate. Further, the first and second channels are disposed side by side. Thus, the temperature of the substrate may be adjusted uniformly as a whole.

An insecticide composition is isolated from Paeonia suffruticosa, Cnidium officinale, Cinnamomum cassia, mustard (Brassica juncea) and horseradish (Cholearia aroracia) by using methanol or by elution with a solvent including hexane and ethyl acetate. The composition can be used to eradicate house dust mites and insects found in stored products.

An apparatus and method for retransmission in a wireless communication system. The method includes transmitting data to a Mobile Station (MS), identifying if there is an error in the transmitted data through a control message, if there occurs an error in the data, allocating resources for retransmitting data for erroneous data, transmitting information on the resources allocated for retransmission, to the MS, and retransmitting the data for the erroneous data to the MS.

An apparatus and method for circuit mode resource allocation in a Broadband Wireless Access (BWA) system is disclosed. The method includes generating a first resource allocation message which comprises currently used slot bitmap information with respect to a circuit mode region in a frame; allocating resources to one or more terminals with respect to currently unused slots in the circuit mode region according to the currently used slot bitmap information; and generating a second resource allocation message which comprises information relating to the resource allocation. Thus, the effective circuit mode resource allocation can be achieved without holes in the circuit mode, while maintaining backward compatibility with the existing standards.

摘要:
A method is provided for performing an authentication procedure according to location registration and update for a mobile subscriber station (MSS) in a broadband wireless access (BWA) communication system. The system includes the MSS operating in idle mode to minimize power consumption, paging groups each being formed by a plurality of adjacent cells in which a plurality of MSSs are paged, base stations (BSs) for paging the plurality of MSSs within each paging group, and a server for controlling location registration and authentication for the plurality of MSSs. The server determines whether to approve a request for transition to the idle mode received from the MSS through a BS. If the server approves the request for the transition to the idle mode, it allocates authentication information to the MSS through the BS and registers location of the MSS. When it is determined that the MSS has moved to a different paging group, the MSS sends a location update request including a resulting value computed using the authentication information allocated from the server. The server authenticates the MSS according to the authentication information included in the location update request and registers the changed location of the MSS authenticated successfully.
