Compared to opencut mining, underground coal mining is more common in Australia due to its lesser impact on the environment. Although there are several underground mining methods, such as the longwall, pillar, bord, and miniwall, longwall mining is the most commonly used method due to its high efficiency. However, longwall mining does lead to significant ground subsidence. Mining subsidence is ...

China and ASEAN have been maintaining a relationship both cooperative and competitive in the textile trade. Due to its labor intensive feature and high dependence on foreign trade , the textile trade has received much attention after the 2008 financial crisis. The customs data (classified by the HS code) from year 2006-2009 is employed to research the impact of the crisis on the trade pattern o...

The realization of Karl Popper’s EPR-like experiment by Shih and Kim (published 1999) produced the result that Popper hoped for: no “action at a distance” on one photon of an entangled pair when a measurement is made on the other photon. This experimental result is interpretable in local realistic terms: each photon has a definite position and transverse momentum most of the time; the position ...

Since the emergence of artificial intelligence and deep learning methods, fault diagnosis bearings in rotating machinery has gradually been realized, reducing high costs bearing faults. However, actual work equipment, faults rarely occur, resulting less data. Therefore, it is necessary to study small sample For case data, Maml–Triplet classification framework based on combination maml triplet n...

To explore the relationship between cutting vibration and load of a single pick, this paper studied new method for pick rock identification. This improved low accuracy problem regularization in inverse process frequency response function traditional identification by introducing filter operator. By combining pseudoexcitation method, dependent on signal was realized. A test equipment built, whic...

3D printing technologies are widely used in world agriculture, but being implemented Ukraine. The use of reverse engineering technology allows to create new products on a ready-made model, as well as, if necessary, make the necessary design changes existing facilities. Therefore, this approach is relevant and opens wide opportunities for modeling agriculture. implementation technological writin...

Recent work in Optimality Theory (Prince and Smolensky 1993, McCarthy and Prince 1993, to appear) has suggested that phonological regularities can be explained without reference to phonological rules, strictly in terms of constraints on representational wellformedness. A unique aspect of Optimality Theory (OT) is that candidates are evaluated in parallel: there is no serial derivation. Given th...
