Complex Systems Modeling

Welcome to the SCL Complex Systems Modeling Research Group Page!

This is a research interest group under the Scientific Computing Laboratory that uses 
various mathematical, statistical and computational techniques to generate insights onto how certain physical, natural, economic, and social systems behave or interact. 

Research Projects

Currently, there are active research projects by the group (AY 2015-2016), which are the following

This study aims to accurately model the recovery of mangrove populations after being damaged by storms. It adapts Salmo and Juanico's agent-based model for mangrove forest growth to a virtual reconstruction of the Bangrin Marine Protected Area in Pangasinan, Philippines. The virtual environment incorporates two models of Heibeler: Fragmented Habitat to simulate variable inhabitability per unit area, and Block Disturbance to simulate the occurence of storms. The model features planted (Rhizophora mucronata) and native (Avicennia and Sonneratia spp.) mangrove species, which have different levels of sensitivity and adaptation to environmental factors.

The Angat-Ipo-La Mesa water system is the main source of water for the Greater Manila Area. Due to the increasing population, climate change, and the lack for new source of water supply, water shortage is imminent. To address this problem, first, this study aims to know when will the demand overtake the supply using Euler approximation method. The resulting projection can identify how much water will be needed in the future and when should a new source for water supply be developed. Next, as a short term solution to water scarcity, improvement on water allocation should be done. The researchers developed a water allocation policy under El Niño phenomenon that will satisfy the demand and maintain an above critical water level of the Angat dam. With the help of this study, water security and security from droughts can be provided for the people of the Greater Manila Area.

3D printing is one of the emerging technologies in science. In the local scene, 3D printers are used by the National Institute of Physics to create miniature models of figures to teach public elementary school students, realizing that visual and hands-on learning is a key tool in teaching Science in early stages of childhood. Since this technology is new in the country, cutting monetary costs is a necessity for average- earning people and government institutions to be able to afford using it. A better value then would mean usability of the technology by the general public, and for the purposes of this research, in the education sector. Minimizing the printing cost would mean cheaper costs not only in monetary value, but also costs in terms of time, effort, and energy. This study aims to find the best orientation (x-y-z axis parameters) of an STL model that gives the least 3D printing time and least use of filament materials through the rotation of the model in 3D space in order to minimize cost.
