Physical, chemical and microbiological characteristics of two 'keiwais' (brackish ponds built along the coastal area for shrimp cultivation) in the Mai Po Marshes, Hong Kong, were measured and compared. One keiwai, located closer to the domestic and agricultural areas, had lower shrimp production than the other. Physical, microbiological and most of the(More)
Reliability design of an aeroengine burner inner-liner is carried out using a bi-variant Lagrange factor polynomial approach. Thermal stress-dependent strength is represented by a discrete random variable that has different conditional probability mean functions under different thermal stress amplitudes. Then the LFP technique is developed to generate the(More)
A generic method is formulated to estimate damage location and extent from the explicit perturbation terms of eigenparameters. Specific permutation numbers and generalized Kronecker delta functions are composed. Stiffness parameters are estimated from these equations, inversely, using BFGS optimization. The algorithm is iterative, and it terminates under(More)
In this research, a stress-strength interference model is developed based on bi-variant Lagrange factor polynomial approach. The first discrete random variable is the independent stress. Thermal stress-dependent strength is represented by the second discrete random variable that has different conditional probability mean functions depending on different(More)
A polynomial method is developed to generate the stress-strength interference model with thermal stress-dependent strength. Accuracy of this method is investigated by an aeroengine fuel centrifugal nozzle. The computed reliability ranges from 0.9845 to 0.9942 under several thermal stress modes. Then steel alloys are chosen for various parts based on their(More)
Standard complex system reliability computation is an important topic for system engineers. Current approaches for reliability analysis are fault tree analysis, true value table or minimal path sets. FTA can not solve many complex problems. This paper introduces the method of Bayesian networks for reliability estimation. The complex systems bayesian(More)
In this paper, a synchronization scheme independent of the sign of the driving signal is developed and analyzed. The corresponding synchronization phenomenon is termed sign-independent synchronization in this context. In our coupling scheme, an even coupling function is used at the response in an attempt to make the response independent of the sign of the(More)
