In view of the anticipated climate change, many countries face increasing risks of flooding. In many countries, flood protection measures will need to be taken in the coming years to protect flood prone areas from the increased risk of flooding. Since the end of the 20th century, the traditional hard flood protection measures are increasingly...

Engaging the right stakeholders at the right time is a key factor to successfully complete a construction project. However, the decision which stakeholders to engage within a project can often be difficult. This research looks into the applicability of visualizations of Social Networks as a tool to support project managers to decide which...

We give an overview of recent developments in error estimation and in residual-based and goal-oriented (adjoint-based) adaptation for Discontinuous Galerkin discretizations of sub- and supersonic viscous compressible flows. We also give an outlook on the planned continuation of this research in the EU project ADIGMA.

This paper investigates to what extent university spin-offs benefit from their parent organization. Drawing from the resource based view and social capital theory we identify the support factors that may turn to interference with the spinoffs business goals. This study has a case study approach and data is collected among high-tech university...

Decision making in the tender phase of large infrastructural projects is a complex task for contractors as they have to make design decisions with long term effects and based on complex client requirements. Further complexity is added by the constrained environment of a tender and the uncertainty of winning the tender. As the context and the...

Although a substantial amount of literature advocates the integrated collaborative design processes for construction projects, very little explicit knowledge exists about the impact of the integrated processes on project uncertainty. In contrast with construction site processes, which can in most cases be organized as a sequence of tasks...

The tiltwing aircraft developed by team MAVerix of RWTH Aachen University is intended to operate in a continuous range of horizontal velocities from hover to fixed wing flight. The design of a flight controller enabling stationary flight states within the entire transition flight envelope demands detailed knowledge of the aircraft’s flight...

Searching for concepts in science and technology is often a difficult task. To facilitate concept search, different types of human-generated metadata have been created to define the content of scientific and technical disclosures. Classification schemes such as the International Patent Classification (IPC) and MEDLINE's MeSH are structured and...

This thesis aims at a contribution to reliable and accurate predictions of complex, multi-phase processes. The reader is presented detailed simulations on liquid and solid-liquid mixing using large eddy simulations (LES) including scalar mixing and particle transport in a Rushton turbine stirred tank geometry. Large eddy simulations have been...

“Access to safe drinking water is a fundamental human need and, therefore, a basic human right. Contaminated water jeopardizes both the physical and social health of all people”: such is the importance of safe drinking water, as stated by Kofi Annan, former Secretary-General of the United Nations, on World Water Day 2001. While some countries...

It is easy to see whether a system in equilibrium is stable when there are only two forces acting on it, as in a swing. But until recently, this was impossible for an equilibrium involving three forces, as in a hammock. A team of structural engineers at TU Delft have discovered a mathematical method of determining the stability of an equilibrium...

Each year some 25 million m3 of mineral sludge are dredged from rivers, canals and harbours in the Netherlands alone, twenty percent of which is polluted. The unpolluted sludge is usually dumped at sea. The remaining five million m3 may only be dumped in a few selected landfill locations, at considerable cost.A sludge flock, hotographed at the...

Door handig gebruik te maken van kooldioxide onder hoge druk kan het voor de fijnchemische industrie veel interessanter worden om gebruik te maken van een bijzondere klasse milieuvriendelijke oplosmiddelen: ‘ionische vloeistoffen’. Onderzoekster dr.ir. Maaike Kroon liet zien dat de besparingen, in elk geval op papier, astronomisch zijn.

Researchers at the Laboratory for Process Equipment at Delft University of Technology have developed an energy-friendly method to separate saline solutions into clean water and pure salt crystals. The method works by crystallizing the water and salt simultaneously though independently from each other. One of the many useful applications of what...

Several companies are implementing the strategy of open innovation in their research and development operations. They become more dependent, therefore, on their capabilities to exchange knowledge and technology with external parties. To facilitate these exchanges, virtual knowledge brokers use web-based information systems. In this paper, we...

A smart use of high-pressure carbon dioxide may make a special class of eco-friendly solvents known as ionic liquids much more attractive to the fine chemical industry. Researcher Dr. Maaike Kroon has demonstrated that, on paper at least, the savings can be astronomical.

The trend in biochemical analysis is to carry out an everincreasing number of tests, in less time, with fewer chemicals. This is why Delft is one of the places where researchers are working on the development of what are known as Labs-on-Chips. The minute dimensions and the minuscule quantities of liquid involved make for a whole new range of...
