Enhanced ultraviolet-B (UV-B) is one of the most important abiotic stress factors that can influence almost every aspect of plant. Selenium (Se) can increase the tolerance of plants to stressful environment. The paper mainly reported the effects of enhanced UV-B, Se supply and their combination on agronomical characters of winter wheat under field(More)
The application of Software Failure Modes and Effects Analysis (SFMEA) and Software Fault Tree Analysis (SFTA) has obvious defects when applied separately. Difficulties of SFMEA to express logical relationship among failure causes, and possibility of SFTA to omit the top events have direct impact on compensating provision. Thus it needs to take integrated(More)
In order to enhance the precision of biofouling estimation, this paper uses Least Squares Support Vector Machine (LSSVM) to establish a prediction model based on the estimator with radial basis function kernel. The main Influencing factors include pH, conductivity, total number of bacteria, dissolved oxygen, TN, NH3-N was selected as the input variable,(More)
