In this Poster, we introduce a decision support system to evaluate and refine complex scenarios addressing the location, timing and technology of water and energy investments in Saudi Arabia. We start by giving insights on the utility of a geographic information system perspective. We explain the different layers we are addressing such as... Continue Reading

In this work, we study the communication dynamics and information propagation of real-world events through the contact networks of mobile phone users. Previous studies have shown that these `bread-crumbs' of digital traces can act as in situ sensors for human behavior, allowing for quantifying social actions and conducting social studies at an...

This paper presents the City Browser, a tool developed to analyze the complexities underlying human mobility at the city scale. The tool uses data generated from mobile phones as a proxy to provide several insights with regards to the commuting patterns of the population within the bounds of a city. The three major components of the browser are... Continue Reading

Abstract—In order to be mindful of the overarching theme of reducing global dependency on oil for energy production, careful execution of current thermal and gas fired conventional capacity must be taken into consideration. Given the high energy demand profiles experienced in some developing countries, heavy investments in renewable and... Continue Reading
