Tea white scab disease commonly occurs in high‐altitude tea‐growing areas worldwide. Both Elsinoe leucospila and Phyllosticta theaefolia have been reported as the pathogen responsible for this disease. To conclusively identify the causative agent, samples were collected from plants infected with tea white scab disease in high‐altitude tea gardens in southern China. Fungal isolates obtained from the...
Objective: To compare the signals of pulse — diagnosis of healthy volunteer in different times in one day. Methods: After collecting the pulse waves of 42 healthy volunteers in 4 specific periods in one day, do pretreatment, parameter extracting basing on harmonic fitting, modeling, and identification by unsupervised learning and supervised learning with cross-validation step by step for analysis...
A novel adaptive algorithm is proposed by combing the sparseness ζ(n) with the value of p applied in lp -- Norm constraint. The convergence process of p is built by estimating and updating the value of p in each iteration, which produces two items, the error item and the constraint item, cooperating with the convergence of w(n). The parameter k is a factor to balance the two items, which...
It is necessary for logistics company's credit risk evalution-makers to comprehensively measure many qualitative and quantitative factors, but theses factors are difficult to evalut. This paper establishes a two-level index system of logistics company's credit risk, which consists of company quality index, supervision capaity index, hardware condition index, credit condtion index. The higher-level...
Prices of services are the increasingly important decision factor to all firms seeking maximum service profits, but it is a very difficult to estimate the prices of service projects, so service price becomes the controversy focus of firms. Activity based costing (ABC) is the optimized method of costing services cost, and the accurate cost information provided by it is playing a very important role...
Height reconstruction error in InSAR system can be divided into fixed and variable height error. Fixed height error can be eliminated by the differential sensitivity equations, so only the system parameter errors, which can cause the variable height error, are involved into the procedure of iterating. To take advantage of these features, the differential interferometric calibration algorithm is proposed...
