The Cul-de-Sac House

The cul-de-sac is an omnipresent urban morphology encompassing an array of very different situations, whose specificity however is overshadowed by its functional definition. The research confronts the functional conception and challenges its appropriateness. It is firstly established that there is no one definition of a cul-de-sac, but rather...

Predictive Modelling of Hydrate Formation and Dissociation

Natural gas hydrates are often considered as a hazard in hydrocarbon production and pipeline transport, but are also recognized as a potential energy resource. Naturally occurring hydrate deposits exist under suitable conditions of low temperature and high pressure, typically in shallow marine sediments and in and below the permafrost, and may...

Formation Flying

A first outline for the concept of formation flying is investigated. The objective is to create a sustainable air transportation system for the next generation of aircraft from a formation flying perspective. When flying in formation over long distances the trailing aircraft can benefit from the wake vortices created by the preceding aircraft....
