Computational assessment of different air-ground function allocations

NextGen and SESAR are re-defining each agent's role in the airspace in terms of autonomy, authority and responsibility. Function allocation is the process of defining authority, i.e., which functions are executed by which agents. This is an essential design decision in creating transformative ATM concepts of operation. This paper presents a...

The discipline of urbanism has its own notions; words with specific meanings, which are used by designers, policymakers and laymen to designate the concrete objects in the world around them: the parts of the city and the urban landscape, and their designs. These plans are always accompanied by written explanations of the designers, critical...

Input reduction for long-term morphodynamic simulations

Input reduction is imperative to long-term (> years) morphodynamic simulations to avoid excessive computation times. Here, we discuss the input-reduction framework for wave-dominated coastal settings introduced by Walstra et al. (2013). The framework comprised 4 steps, viz. (1) the selection of the duration of the original (full) time series of...

Housing and the welfare state: Changing perspectives and a research agenda

The relationship between housing and the welfare state is a heavily researched topic in international comparative housing research. This exploratory paper provides a historical overview of the academic debate. For a long time, the discussion primarily focused on the degree and the nature of government intervention within the field of housing....

Social housing in the Netherlands: The development of the Dutch social housing model

This is due to the fact that the Dutch social rental sector has a large size, offers dwellings of a relatively good quality and functions without receiving substantial subsidies. However, current poli-cies, both at the European and the...

Pilot Project Sand Groynes Delfland Coast

In October and November 2009 a pilot project has been executed at the Delfland Coast in the Netherlands, constructing three small sandy headlands called Sand Groynes. Sand Groynes are nourished from the shore in seaward direction and anticipated to redistribute in the alongshore due to the impact of waves and currents to create the sediment...

A comprehensive sediment budget for the Mississippi Barrier Islands

In order to conceive any realistic plan for post-Katrina island restoration, it is necessary to understand the physical processes that move sand along the littoral drift zone off the coast of Mississippi. This littoral zone influences the character of the Mississippi barrier islands as they exist in an ever changing cycle. To help in this...

New trends in the Dutch housing market

Every few years the planning agencies in the Netherlands draw up a prognosis for the future housing needs on the basis of economic and demographic scenarios. It is our contention that, in applying this approach, the agencies neglect to take sufficient account of the influence of cultural dynamics. A recent recommendatory report by the Dutch...
