This paper describes an experiment that employs an incremental approach to distribute a genetic algorithm application. The incremental approach allows the application to be initially developed for a standalone system, and then extended to run on multiple systems concurrently. For the extension, design patterns are employed wherever appropriate. The use of(More)
Based on the theoretical model, a numerical method is usually necessary for obtaining the optimal preventive maintenance (PM) policy for a deteriorating system since the theoretical model becomes complicated when the system's hazard rate function is changed after each PM. It makes the application of the theoretical model not suitable for real cases.(More)
Citrus mandarin (Citrus reticulata) cultivar Shatangju has great economic importance in southern China because of its delicious fruit and medicinal peel. During surveys conducted in 2012 and 2013, stem rot and plant death were observed on 2- to 3-year-old Shatangju grafted seedlings in 21 nurseries located in three regions (Yangjiang City, Sihui City and(More)
BACKGROUND AND OBJECTIVE Gonorrhea is a sexually transmitted disease caused by the bacterium Neisseria gonorrhoeae. Rapid detection is crucial for effective prevention and treatment. This study developed and tested a low-cost effective method for detecting N. gonorrhoeae, especially in developing countries. METHODS DNA from a N. gonorrhoeae standard(More)
Preventive maintenance (PM) can slow the deterioration process of a repairable system and restore the system to a younger state. The proposed PM model of this paper focuses on the restoration effect of degradation rate reduction which can only relieve stress temporarily and slow the rate of system degradation while the hazard rate is still monotonically(More)
