This study proposes a novel mathematical model based on excitation system output equations (ESOEs) to evaluate the steady-state performance of the three-phase brushless asynchronous excitation system (BAES) of a wound-field synchronous aircraft starter–generator system. The steady-state performance could be used to evaluate the field current output capabilities of the BAES and provide a reference...
To solve the slow convergence or non-convergence problem of traditional distance dynamics method, an improved community detection algorithm based on distance dynamics is proposed in this paper for speeding up the time efficient and accuracy of algorithm. Our improved algorithm firstly analyzes the node cohesiveness and slow convergence problems. Secondly, the neighbor cohesion is defined and two new...
In current biological image analysis, the temporal stage information, such as the developmental stage in the Drosophila development in situ hybridization images, is important for biological knowledge discovery. Such information is usually gained through visual inspection by experts. However, as the high-throughput imaging technology becomes increasingly popular, the demand for labor effort on annotating,...
With the fast development and popularity of digital cameras, smart phones, and video surveillance devices, the amount of video data increases dramatically. Accordingly, automatically mining and annotating high-level concepts for video indexing and management become imperative research tasks in both multimedia research and data mining research. The mainstream content-based semantic concept mining approaches...
Automatic high-level semantic concept detection is a crucial step for multimedia data management, indexing, and retrieval. It is well-acknowledged that semantic gap poses a great challenge in multimedia content-based research. It becomes even more challenging when the concept of interest is extremely rare in the training data sets because of the poor modeling for the positive instances. In this paper,...
This paper considers the centralized energy supply system model which include the winter heating and summer cooling, The author carries on the analysis and the computation through the compressor, condenser and evaporator's power, the heat transfer and the flow quality, then establishes a steady-state mathematical model of water Source Heat Pump, which applied thermodynamics theory, the parameter distribution...
The subliminal channel is a covert communication channel constructed in public correspondence pattern. As a kind of the modern information hiding technology, it is used to transmit the secret information. In this paper, the subliminal channel in general ElGamal signature is analyzed. And the wideband and narrowband subliminal channel in the broadcast digital multi-signature is discussed on the presence...
