Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...

Similar to many energy projects, the evaluation of investments in natural gas projects is influenced by technical and economic uncertainties. These uncertainties include resource characteristics, production, decline laws, prices, taxes, benchmark yield, so on. In China, conventional still dominant source. The investors are mainly large state-owned companies. Therefore, it necessary uncertaintie...

The development of optimization and mathematical models for closed loop supply chain (CLSC) design has attracted considerable interest over the past decades. However, the uncertainties that are inherent in the network design and the complex interactions among various uncertain parameters are challenging the capabilities of the developed tools. The aim of this paper, therefore, is to propose a n...

The operability limits of a supersonic combustion engine for an air-breathing hypersonic vehicle are characterized using numerical simulations and an uncertainty quantification methodology. The time-dependent compressible flow equations with heat release are solved in a simplified configuration. Verification, calibration and validation are carried out to assess the ability of the model to repro...

Preaspiration is usually associated with stops rather than fricatives, both at phonological and phonetic levels of description. This study reports the occurrence of phonetic (nonnormative) preaspiration of voiceless fricatives in Scottish Standard English (SSE) spoken in the Central Belt of Scotland. We classify it as non-normative because it is variably present in different speakers, but the d...
