Distributed storage systems have the advantages of self-organizing, scalability, robust and fault-tolerant, which provide fundamental support for mission-critical applications. Unfortunately, there still exist some problems in real network conditions, especially, when considering asynchronous distributed environments, where messages may be delayed indefinitely and nodes may fail. So, failure detector...
Coal mine underground drainage system undertakes the important task of draining all the inflow produced during the process of production in underground coalmine, hence it is important equipment in mine production. The design of monitoring and control system of underground drainage pump is thus particularly important. In this paper, according to the practical underground work situations of a mine,...
Digital instrumentation and control systems has been widely used to high-risk system, which changes the context influencing human performance, cognitive processes and human-machine interaction, thus lead to new human errors and error mechanism. This paper constructs the extended human error analysis model for analyzing the possible cognitive and action errors. And then human error causal factors are...
Low power design has always been critical to high performance. With the latest technologies, being able to significantly reduce any portion of the overall system power becomes an absolute requirement for extending the lifetime of the system. Clock generation and clock tree distribution are always identified as a significant portion of the power dissipated in a chip. We describe here a servocontrol...
Hydrogen sulfide (h2s) leakage and dispersion from a sulfide recycle installation in different wind speeds are simulated by implementing a 3D Computational Fluid Dynamics (CFD) model. h2s concentrations of monitor points which represent dispersion contours and dangerous areas have been recorded. Dispersion disciplines and consequences in different wind speeds have been compared. The toxic load has...
