Parameter Estimation on Two-Dimensional Advection-Dispersion Model of Biological Oxygen Demand in Facultative Waste Water Stabilization Pond: Case Study at Sewon Wastewater Treatment Facility

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 3, Page # 11–15, 2020; DOI: 10.25046/aj050302
Abstract:

To build a precise mathematical model describing a natural phenomenon, parameter estimation is needed to achieve the best parameter value. In this paper, we have calculated the best parameter value for a two-dimensional advection-dispersion differential equation of the biological oxygen demand degradation process in a facultative wastewater stabilization pond. This research was conducted with case…

Multi-period Quadratic Programming Model for Sewon-Bantul Facultative Ponds Optimization

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 6, Page # 397–401, 2019; DOI: 10.25046/aj040650
Abstract:

Treatment plants have been developed in many countries to handle wastewater, therefore, many pieces of researches have been conducted in order to optimize the outcomes. In this article, a mathematical optimization model was developed using quadratic programming approach to optimize the pollutant degradation at the domestic wastewater facultative stabilization ponds. The data used in this…

Multi-Restricted Area Avoidance Scenario Using Hybrid Dynamical Model and Its Predictive Controller

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 4, Page # 147–151, 2019; DOI: 10.25046/aj040418
Abstract:

This article is addressed to show the results of hybrid dynamical modeling in the form of PWA (piecewise-affine) and equivalent MLD (mixed-logical dynamical) model for multi-restricted areas avoidance of an autonomous system. It is a problem of determining the optimal moving trajectory from plant’s initial position to some desired position while avoiding some restricted areas…
