Urban Soils as Hotspots for Carbon Storage: A case study of the urban greenspaces of The Hague, the Netherlands

The services that society extracts from urban ecosystems are becoming increasingly important with increasing urbanization. A potentially crucial ecosystem service is soil carbon (C) storage, as negative soil C balances have the potential to offset some of the anthropogenic greenhouse gas emissions mitigating climate change. This research studied...

Direct Numerical Simulations of Boundary Layer Stability for Non-ideal Fluids

The process in which a smooth laminar flow transits to a chaotic to a chaotic, turbulent state, is a topic of particular interest in the sectors of energy technology and aerodynamics. To study the different paths that can be followed during the transition process, various tools and methods have been developed. A preliminary investigation of the...

Synthesis of a Long Vertically Aligned Carbon Nanotube Array by Chemical Vapour Deposition

Although a lot of research has been devoted to the growth of a long Vertically Aligned Carbon Nanotube Array (VANTA), it remains difficult to find the right parameters on new systems. It has turned out that the recipe that allows the growth of Carbon Nanotube (CNT) in a particular Chemical Vapour Deposition (CVD) oven is very specific and not...

A Visual Life Cycle Analysis - for architects and policymakers

The impact of urbanizing 400 million people in China in 20 years - a comparative analysis of common structural materials with bamboo as a promising alternative for (semi) high-rise developments. Transport, End of Life scenarios and Lifespan are essential factors in a Life Cycle Analysis (LCA). The Building Energy Use itself is becoming less...

The design of a luxury superyacht tender based on the 12,3m RIB hull of Xtenders

This project started with a visit to Xtenders where a tough model of a new concept came to my attention. This sketch looked different from at the time produced by Xtenders models and evoked some curiosity that emerged into the graduation thesis. Xtender is a Dutch brand that builds yacht tenders. The main advantage of the product has been...

Feasibility study on fiber reinforced polymer cylindrical truss bridges for heavy traffic

Considering the recent increase in the use of fiber reinforced polymers in the civil engineering industry in general and in the bridge engineering industry in particular, as well as the recently more and more applied cylindrical truss bridge type, this research focuses on the question whether it is possible to combine fiber reinforced polymers...
