An approach of on-line condition monitoring and mixed faults diagnosis for the squirrel cage induction motors is introduced in this paper. The proposed approach is based on spectral analysis of the average instantaneous power, which requires no stator or rotor parameters and has ability to separate mixed rotor faults. Theoretical analysis and experimental(More)
Towards the reactive compensation feature of distribution network and integral substation, this paper proposed an integration structure of distribution transformer and STATCOM (DT-STATCOM). It use the surplus capacity of transformer to compensate the reactive power; by setting the connect voltage flexible, it extended the switching devices selection; the(More)
In view of the traditional parallel FP-growth algorithm (PFP)that suffers from two major limitations, namely, multiple database scans requirement (i.e., high I/O cost) and high inter-processor communications cost, therefore we design and implement a parallel association rules mining method based on cloud computing. The algorithm adopts the separation(More)
In this paper, it is based on the theory of aerodynamics and one 1∶1 heavy-duty commercial vehicle geometry was built. The numerical simulation of the vehicle was completed by modifying the geometric model, simplifying the mesh and solving the control equations, Using computational fluid dynamics(CFD) commercial software—Ansys Fluent to(More)
Adenylate cyclase 3 (AC3) is one of the major players in the olfactory signaling within the main olfactory epithelium (MOE) of mice. However, we are not ascertained whether deficiency of AC3 will lead to the differential expression of related genes in the MOE. Forward and reverse subtractive libraries were constructed by suppression subtractive(More)
This paper proposes a new fault location method in distribution networks using Prony analysis. This method just needs the measured voltage transients without multi-recording nodes. Fault-originated traveling waves propagate along the distribution network and reflect at the discontinuity points, so the recorded transients contain some characteristic(More)
Gold/double-cable copolymer/gold multisegmented nanorods were prepared electrochemically via a template-based method. These "bulk heterojunction" nanorods showed photoconductivity providing us with a platform to study photoinduced charge separation/transport at the nanointerface and begin to think about the rational design of nanoscale solar cells based on(More)
The method of normalized digital orthogonal detection is proposed according to the frequency of surface Magnetic Resonance Sounding (MRS) signal is much bigger than bandwidth and it has no influence on its key parameters. Constructing MRS signal with noise in accordance with its characteristics, then processing them using normalized digital orthogonal(More)
Digitization has played a profound role in promoting the transition of the traditional teaching mode of landscape architecture. The traditional teaching mode of the landscape architecture curriculum cannot fully meet the needs of the new design curriculum. Based on the existing problems and taking advantage of digitization technology platform, this paper(More)
The properties of adsorption of shikimic acid by activated carbons were investigated in batch experiments. The adsorption of shikimic acid was strongly influenced by temperature. The Freundlich and Langmuir models were used to fit experimental data. The results of regression showed that the Freundlich equation was more suitable. Some thermodynamic(More)
