This paper proposes a general scheme for optical access networks which adopt optical CDMA, discusses some key technologies of CDMA such as spectrum-spread coding/decoding, channel interference canceling and power controlling, and analyzes and compares several access methods in optical access networks.
Command control system is important part of tank integrated electronic system,this paper discuss the trait of tank command control system and give the way of construct and design of tank command control system in condition of integrated electronic system.
According to the characters of housing surveying,the quality elements of inspection are determined,the method of division of the sample unit is proposed to inspect the digital housing flat map,and the sample inspection themes are presented to check the housing surveying products. The normal theme is provided,and the detailed measures of inspection are established in JS-GIS.
Different from normal IWR schemes, the IWR system in this paper does not implement a speech analysis unit, but to borrow the speech analysis unit, the GSM EFR voice coder, from the communicating system to perform the speech analysis.
We have designed a two-stage packets scheduler to satisfy the QoS requirement in Internet. This is based on the analysis of the QoS scheme in Internet.
Then I compared the project with common project for testing their max mobile speed and bit rate. Finally the test data could validate the credibility of improvement and function in mobile reception and transmission performance of the DVB—T system receiver.
A general scheme of cyclic multiphase behavior of interacting production subjects in the conditions of regular payments and no competition was proposed.
Models of limited life span in the animal organism were discussed, and a general scheme of the vital processes in organism, ageing, and death was presented.
A general scheme for the effect of chloride anions on activity of the C-domain of bovine angiotensin-converting enzyme accounting for binding the "activating" and " inhibiting" anions is suggested.
Thirty six patients, age range 21-75 years (median-45) years) with recurrent and advanced histologically proven squamous cell carcinoma of cervix were treated with chemotherapy using a combination of bleomycin, ifosfamide and tisplatinum (BIP) . Thirty two patients were evaluable for response. 90% patients achieved subjective response.Objective response were seen in 18/ 32 (56%) patients: complete-7 (21.8%) , partial-11 (34.3%) patients. Average relative dose intensity (ARDI) for all patients as calculated ...
This paper discusses a procedure of tetrahdr1 mesh generation using the advancing frontapproach in a volum e region with arbitrary shape and proposes a general scheme to generate atypical tetrahedral element in the procedure. A simple generalized Laplacian smoothing scheme fortriangular meshes on a 3D non-planar surface region and a smcothing sc heme for tetrahedralmeshes in a volume region are presented.Some graphic results are given to illustrate theperformance and capability of the present mesh generator...
Intranet is a new technology which appears recently. The enterprise can establish its own network rapidly and efficiently,and its cost is very low. The article introduces the characteristics of this technology in delail and gives a general method to establish an intranet.
