Wax precipitate is one of the most serious issues the oil industry is currently facing, since it can cause some troubles such as increasing of the pressure losses in pipe which subsequently increases the required power for pumpage. To remove this problem, prediction of wax disappearance temperature (WDT) seems necessary. In this study, the pressure influence on the wax disappearance temperatu...

Bidirectional transformation (bx) approaches provide a systematic way of specifying, restoring, and maintaining the consistency of related models. The current diversity of bx approaches is certainly beneficial, but it also poses challenges, especially when it comes to comparing the different approaches and corresponding bx tools that implement them. Although a benchmark for bx (referred to as a...

Technological progress has led to electronic exchanges attracting a major part of transaction volume for standardized stocks. In the field of derivatives and bonds, electronic exchanges failed to prosper and so called over-the-counter (OTC) trading is predominant: possibly because multi-attribute assets are hard to trade in structured two-sided markets. The present paper aims at alleviating thi...

Efficient wholesale markets should drive preference revealing bidding where generators offer the majority of their power at short run marginal cost (SRMC). However, most renewables have very low SRMCs, which in a competitive market is likely to lead to an increasing proportion of low priced periods. This has led to suggestions that a capacity market may be required in the Australian National El...

We propose a new herd mechanism and embed it into an open financial market system, which allows traders to get in and out of the system based on some transition rates. Moreover, the novel mechanism can avoid the volatility disappearance when the population scale increases. There are three kinds of heterogeneous agents in the system: optimistic, pessimistic and fundamental. Interactions especial...
