Retrieval of leaf biochemical parameters from reflectance measurements using model inversion generally faces “ill-posed” problems, which dramatically decreases the estimation accuracy of an inverse model. While the standard approach for model inversion retrieves various parameters simultaneously, usually only based on one merit function, the new approach proposed in this paper assigns a specific merit...
Tiling array is one type production of Affymetrix short oligonucleotide microarrays to map transcriptional factor binding sites (TFBS) at a high resolution. In order to estimate the quantity of target sequences of probes, we model the binding behavior between probes and DNA sequences at molecular interaction level and term it hybridization model for tiling array analysis (HMT). In our model, the binding...
Based on analysis of former matter element extension evaluating model, author points out the former model's limitation that the model can not be used when observed data are bigger than the section field value in evaluation of water quality. Combining synthesis weights with approach degree, a new matter element extension evaluating model based on synthesis weights and approach degree is established...
Turbine through-flow model is the great part of the performance analysis model and fault diagnose. However, the performance analysis and fault diagnosis in power plants is depend on plenty of thermal parameters of which the reliability and accuracy are very important for real-time monitoring and automatically control. The results of traditional models would be impacted by the inaccurate parameters...
The running equipment of industrial system may be affected by not only the conditions of the system but the operating state itself, so that the risk of equipment failure was considered as dynamics. During researching the possibility and severity of the failure risk, it is necessary to understand and investigate the dynamic characteristics of equipment failure in the system life cycle. In this article,...
Matrix rectifier (MR) is a buck rectifier in nature, which can be reduced from the traditional matrix converter. Like other converters interfaced with the power lines, it hardly avoids the problems caused by the abnormal cases of three-phase input voltages. The existing basic PWM algorithms of MR include current SVM algorithm and switching function algorithm, suitable for normal power supply. In view...
