Determination of Optimum Smoothing Constant of Single Exponential Smoothing Method: A Case Study [PDF]

open access: yesInternational Journal of Research in Industrial Engineering, 2017
Exponential smoothing is a sophisticated forecasting method that works based on previous forecast plus a percentage of the forecast error. A key issue of this technique is the proper choice of exponential smoothing constant.

An efficient non-iterative smoothed particle hydrodynamics fluid simulation method with variable smoothing length

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2023
In classical smoothed particle hydrodynamics (SPH) fluid simulation approaches, the smoothing length of Lagrangian particles is typically constant. One major disadvantage is the lack of adaptiveness, which may compromise accuracy in fluid regions such as
