This paper firstly explains the principle of the eliminating noise method by the multi-dipole observation system of geoelectric field. Then based on the observation data of the multi-dipole observation system obtained by ZD9A telluric current monitors installed in Chongming and Nanjing stations, we study the abnormal variation of the geoelectric field preceding the earthquakes. The study shows that: a) Eliminating noise method of multi-dipole observation is an excellent method by which many kinds of geoelec-tric field noises can be eliminated successfully and the geoelectric precursor information can be recognized; b) The geoelectric precursor signals for the events were recorded on the NS and NE dipoles in Chongming station 42 days, 20 days and 2 days before the earthquakes respectively, in which the station is near the epicenter, and the longest time of persisting period was 9 days. The abnormal variation signals of geoelectric field observed in Nanjing sta-tion are all the noises but not the seismic electric signals, in which the station is not near the epicenter; c) Dipole distribution method of common electrode is not good in the multi-dipole observation system of the geoelectric field.展开更多

Dye exhaustion and bonding on polyester/wool samples are studied under different experimental conditions - the LAB amount, the temperature and pH value- to achieve optimum conditions. The results are compared with those obtained with and without conventional dyeing auxiliary products. Although dye exhaustion is higher in the presence of commercial carriers, the dye bonded increases markedly in the presence of auxiliary LAB in both fibers. The role played by auxiliary LAB in polyester/wool blend dyeing can provide a new method for this process.展开更多

Since service and information resources have distributed, autonomic, remotely bound as well as some other similar characteristics, an implementation mechanism on managing shared resources based on UDDI are presented. XML instances are used to describe resources authorization information, WSDL based special XML instance represents information resource metadata, and these XML instances are referenced by tModel for realizing the purpose of managing shared resources metadata based on UDDI.展开更多

Aerial photograph interpretation with fieldwork is applied to draw the outlines of geomorphic types. Based on the investigative data, the exogenic forces and marine organism conditions concerning tropical coast development in the area are expounded, and coastal dynamo-deposition geomorphic bodies are analysed, mainly with sea cliff-abrasion platform,barrier-lagoon system, modern beach, coral reef and mangrove tidal flat, and the general process of coastal evolution at this area, as well as coastline changes since middle Holocene transgression.展开更多

Hw/Sw co design is a modern technique aimed at shortening the time to market in designing the real time and embedded systems. Key feature of this approach is simultaneous development of the program tools and the target processor to match software application. An effective co design flow must therefore support automatic software toolkits generation, without loss of optimizing efficiency. This has resulted in a paradigm shift towards a language based design methodology for microprocessor optimization and exploration. This paper proposes a formal grammar, UNI SPEC, which supports the automatic generation of assemblers, to describe the translation rules from assembly to binary. Based on UNI SPEC, it implements two typical applications, i.e., automatically generating the assembler and the test suites.展开更多

In comparison with the traditional G-STBC coding scheme, the proposed space-time code has longer code length and adopts proper rotation-based symbols, which can increase the minimum distance of space-time codes and thereby improve code gain and achieve full diversity performance. The simulation results verify that the proposed group space-time code can achieve better bit error performance than both the traditional group space-time code and other quasi-orthogonal space-time codes. Compared with Ma’s full diversity full rate (FDFR) codes, the proposed space-time code also can achieve the same excellent error performance. Furthermore, the design of the new space-time code gives another new and simple method to construct space-time codes with full diversity and high rate in case that it is not easy to design the traditional FDFR space-time codes.展开更多
