Objectives: The aim of the study was to identify factors that influence the current and future demand for and supply of...

An elastic-degenerate (ED) string is a sequence of $n$ sets strings total length $N$ which was recently proposed to model set similar sequences. The ED matching (EDSM) problem find all occurrences pattern $m$ in an text. EDSM has received some attention the combinatorial community, and $\mathcal{O}(nm^{1.5}\sqrt{\log m} + N)$-time algorithm known [Aoyama et al., CPM 2018]. standard assumption p...

To perform any economic management of a petroleum reservoir in real time, a predictable and/or updateable model of reservoir along with uncertainty estimation ability is required. One relatively recent method is a sequential Monte Carlo implementation of the Kalman filter: the Ensemble Kalman Filter (EnKF). The EnKF not only estimate uncertain parameters but also provide a recursive estimat...
