Innovation is the decisive force in the sustainable development and the intrinsic motivation for industrial clusters to gain competitive advantages. Firstly, the article constructs a unified platform to research cluster Innovation through the integration method of the object “Network” on the ontological and methodological sense. Network is both the target of innovative research, but also the method...
A large doppler frequency shift will be produced under high dynamic environment,and GPS receiver cost longer time to capture satellite signals. That is a great drawback to some high dynamic carrier especially to some high-speed guided weapons. The paper proposed an acquisition algorithm aided by inertia information under high dynamic environment. Here the real-time speed and position of carrier is...
For monitoring ships, buoys and water levels information, a new waterway monitoring system is proposed. The pooled service and tile-caching technologies are further utilized to improve capacity of multi-user concurrent accessing and to speed up the chart displaying performance. In addition, based on ArcGIS nautical solution and ArcGIS server, data processing, standardized display and service publishing...
Civil air-transport, it's difficult to avoid the appearance of air disruption for many reasons. Aircraft mechanical problems, severe weather, crew sickness, airport curfews and security are the problems that force an airline to delay or even cancel their regular published flights. Air disruption not only affects the normal operation of the airlines, bringing many tourists trouble, but also makes huge...
In keyword search over relational databases (KSORD), retrieval of user's initial query is often unsatisfying. User has to reformulate his query and execute the new query, which costs much time and effort. In this paper, a method of automatically reformulating user queries by relevance feedback is introduced, which is named VSM-RF. Aimed at the results of KSORD systems, VSM-RF adopts a ranking method...
