The Department of Civil and Environmental Engineering at the Massachusetts Institute of Technology is dedicated to balancing the built environment with the natural world. In our research, we seek to understand natural systems, to foster the intelligent use of resources and to design sustainable infrastructure systems.

In his logical papers, Leo Esakia studied corresponding ordered topological spaces and order-preserving mappings. Similar spaces and mappings appear in many other application areas such the analysis of causality in space-time. It is known that under reasonable conditions, both the topology and the original order relation ≤ can be uniquely reconstructed if we know the interior < of the order rel...

We consider a multi-attribute outsourcing economy where both price and delivery date are relevant decision factors. In the economy, there is an Original Equipment Manufacturer (OEM) who needs multiple items to be delivered on the predetermined delivery dates and suppliers who are capable of delivering some or all of the items. We first show that there exists a competitive equilibrium in this ec...

Disc jockeys are in some ways the ultimate experts at selecting and playing recorded music for an audience, especially in the context of dance music. In this work, we empirically investigate factors affecting track selection and ordering using mixes created for the Essential Mix. The Essential Mix is a well known weekly radio show on BBC Radio 1 that showcases various styles of electronic dance...

When annotating non-standard languages, descriptively incomplete language phenomena (EAGLES, 1996) are often encountered. In this paper, we present examples of ambiguous forms taken from a historical corpus and offer a classification of such descriptively incomplete language phenomena and its rationale. We then discuss various approaches to the annotation of these phenomena, arguing that multip...

accurate estimation of hydrocarbon volume in a reservoir is important due to future development and investment on that reservoir. estimation of oil and gas reservoirs continues from exploration to end of reservoir time life and is usual upstream engineer’s involvements. in this study we tried to make reservoir properties models (porosity and water saturation) and estimate reservoir volume hydro...
