It is important to consider diagnostic coverage (DC) of the automatic diagnosis (AD) scheme in course of the design of highly reliable systems in which redundancy technique is usually applied. Considering the nature of AD is to introduce some form of redundancy, its performance will be affected by common cause failure (CCF). Due to that diversity is an effective antidote for CCF, it is desirable to...
The commercial computer fluid dynamics software package FLUENT was used to simulate the flow field of the new toilet system. The mesh model of the flow field was built with the GAMBIT. With the numerical simulation of the flow field on air intakes and flushing system, the pressure and velocity vector cloud diagram have been given. The information would be very useful in experimental investigation...
A novel particle swarm optimization (NPSO) algorithm with dynamically changing inertia weight based on fltness and iterations was presented for improving the performance of the Particle Swarm Optimization algorithm. The new algorithm was tested with three benchmark functions. The experimental results show that the swarm can escape from local optimum, and it also can speed up the convergence of particles...
Based on the maximal velocity distribution uniformity, the minimal velocity-weighed average bias angle of the outlet section and the minimal hydraulic loss of the suction chamber, three optimum object functions of suction chambers of pipeline pumps are established. According to uniform design, ten optimum schemes are determined with the height H3 and the length L as the optimum parameters, and internal...
Network torn is a key method in analog circuit fault diagnose. Generally, all torn terminals must be mensurability in implementing network tearing. In accordance with the restrictions, presenting partition conditions of solvable subnet those partial torn terminals inaccessible, this paper analyze mensurability of subnet to lay the groundwork of further fault location.
