A multi-head-attention-network-based method is proposed for effective information extraction from multidimensional data to accurately predict the remaining useful life (RUL) of gradually degrading equipment. The features desired equipment were evaluated using a comprehensive evaluation index, constructed discrete coefficients, based on correlation, monotonicity, and robustness. For extraction, ...

We define fuzzy constraint networks and prove a theorem about their relationship to fuzzy logic. Then we introduce Khayyam, a fuzzy constraint-based programming language in which any sentence in the first-order fuzzy predicate calculus is a well-formed constraint statement. Finally, using Khayyam to address an equipment selection application, we illustrate the expressive power of fuzzy constrai...

PROBLEM Operators of roof bolting machines in underground coal mines do so in confined spaces and in very close proximity to the moving equipment. Errors in the operation of these machines can have serious consequences, and the design of the equipment interface has a critical role in reducing the probability of such errors. METHODS An experiment was conducted to explore coding and directional...

As microelectronics device feature sizes continue to shrink and wafers continue to increase in size, it is necessary to have tighter tolerances during the fabrication process to maintain high yields. Feedback control has, therefore, become an important issue in plasma processing equipment design. Comprehensive plasma equipment models linked to control algorithms would greatly aid in the investi...

Balloon valvuloplasty techniques and equipment have continued to evolve over the last two decades. With this expanded experience, there has been refinement in patient selection and a clearer understanding of the benefits, limitations, and long-term results of balloon valvuloplasty. In this chapter the mechanisms, indications, techniques and clinical results of balloon valvuloplasty of the mitra...

Chevron Australia, as part of the Wheatstone Project, is constructing a two train liquefied natural gas (LNG) facility and domestic gas plant at the Ashburton North Strategic Industrial Area, 12 kilometres west of Onslow on the Pilbara coast of Western Australia. The initial two-train facility design capacity is 8.9 million tonnes per annum (MTPA). Eventually, the facility could expand to produ...
