At present, the checking and designing of SCD's virtual terminal in smart substation are used by hand, and their rationalities are not easy to be verified. This paper studied a kind of searching and analyzing method of device virtual links based on historical SCDs. The virtual links are extracted from a number of existed SCDs, and stored into the database as the templates. For the SCD's receiving...
Sparse unmixing is based on the assumption that each mixed pixel in the hyperspectral image can be expressed in the form of linear combinations of a number of pure spectral signatures that are known in advance. Despite the success of sparse unmixing based on the L0 or L1 regularizer, the limitation of this approach on its computational complexity or sparsity affects the efficiency and accuracy. In...
Objective: Systematically review the value of second-trimester triple serum tests screening for Down's syndrome by using meta analysis. Method: The literature on PubMed, Journal of Medicine Library, CNKI, Web of Knowledge from January 2000 to April 2014 concerning second-trimester Down's syndrome screening was retrieved by computer or by hand. The literature was evaluated based on the QUADAS quality...
This paper proposes multigoal implementations of the Dijkstra's shortest path algorithm and the boundary iterative-deepening depth-first search (BIDDFS). The algorithms were modified to allow for the search of more than one goal in a single expansion pass. The aim of this is to reduce the operational redundancy and hence the time taken for calculating multiple start-goal node pairs. Simulations using...
[Purpose] To apply the “on/off” switch of 3′ exonuclease in single base discrimination of L191P and F275S mutations in gene KCNQ1 which are the mutations found in Chinese patients of LQTS. [Methods] A large amount of templates of wild type and mutation type were prepared by primer extension performed using polymerases without 3′ exonuclease activity respectively. Allelic specific primers targeting...
According to the characteristics of fresh agricultural product, studies the inventory model for fresh agricultural product on the condition that the storage is allowed out of stock, the demand is increasing exponentially over time, the deterioration rate is three-parameter Weibull distribution and has a storage capacity constraint. The minimum average total cost of the system as the objective function...
