Pocket drones, weighing less than 50 grams, are small, agile and inherently safe. This makes them suitable for several surveillance tasks such as search and rescue, green-house monitoring and pipe-line inspection. In order for a more efficient search, a swarm of pocket drones would be ideal to explore these types of areas faster. Current methods...

This paper presents a practical dynamic programming based methodology to optimize the long-term maintenance check schedule for a fleet of heterogeneous aircraft. It is the first time that the long-term aircraft maintenance check schedule is optimized, integrating different check types in a single schedule solution. The proposed methodology...

Port cities face enormous sustainability challenges. In this chapter, we propose a relational view of these challenges, exploring how governance tries to connect the three pillars of sustainable development—economic, social, and environmental—and addresses the contradictions inherent to new port plans or waterfront projects. We zoom in on the...

Success Likelihood Index Model (SLIM) is one of the widely-used deterministic techniques in human reliability assessment especially when data is insufficient. However, this method suffers from epistemic uncertainty as it extremely relies on expert judgment for determining the model parameters such as the rates and weights of the performance...

The present work deals with oxide dispersion strengthened (ODS) Eurofer steel fabricated by powder metallurgy involving mechanical alloying and spark plasma sintering. A heat treatment route including normalising and tempering was applied to the as-produced steel, based on differential scanning calorimetry (DSC) measurement. The...

In this letter we show how the problem of assessing structural local stability of BDC-decomposable systems, left open in recent literature, can be solved via convex optimisation. First we give a simple test, based on a sufficient condition, that requires checking the strict co-positivity of a multivariate polynomial. Then we provide a...

An important challenge in synthetic biology is the construction of periodic circuits with tunable and predictable period. We propose a general architecture, based on the use of recombinase proteins and negative feedback, to build a molecular device for periodic switching between two distinct regimes; the switching rule depends on known...

This study analyzes how learning costs for technologies that lack de facto standards, such as mobile payment, affect user intentions. In addition, we evaluate how the negative effect of learning costs is mediated by perceived functional value and facilitating conditions. Data used in this research was obtained from a study among 463 consumers....

This paper identifies safety concerns that arise from ongoing technical and institutional changes in the Dutch gas sector. The Netherlands has a well-developed gas infrastructure that primarily transports natural gas, although its constituting features are undergoing major changes. We identify three historical developments, and show how (1)...

This paper presents the results of an experimental research aimed at assessing the material performance of adobe bricks in compression for a wide range of induced strain rates, from statics to high velocity impact. Adobe connotes a traditional masonry whose bricks are made of sundried soil mixtures possibly reinforced with natural fibres and...

This chapter focuses on a traditional Iranian water infrastructure, the qanat system, a technical solution to the problem of accessing water for irrigation and urbanization that has shaped the landscape and organized the territory. The qanat was the basis for habitation, construction, and prosperity (abadani). It is also a key to understanding...

Cities worldwide currently face freshwater shortages. Forecasts predict that demand will outstrip naturally renewable and available water supplies by 40% by 2030. This poses a serious threat to livability in cities and urban areas that are already struggling with water-related issues like floods and land subsidence. Water insecurity, in...

The redevelopment of the New Dutch Waterline, also known as the New Hollandic Waterline, was crucial to a change in public appreciation of Dutch military heritage and its connection to landscape design. Starting in 1980, new methods of revitalization combined preservation, renewal, and narrative approaches. At the same time, the work on the New...

The Netherlands has a centuries-long tradition of reclaiming land. In the last century gaining land from water peaked with the IJsselmeerpolders, made possible by technical innovations. The Noordoostpolder (1937–1942), one of the IJsselmeerpolders, is a unique example of a fully designed agricultural landscape of the twentieth century. It is the...

In this paper we consider L<sup>p</sup>-regularity estimates for solutions to stochastic evolution equations, which is called stochastic maximal L<sup>p</sup>-regularity. Our aim is to find a theory which is analogously to Dore's theory for deterministic evolution equations. He has shown that maximal L<sup>p</sup>-regularity is independent of...

We need to tell a new story about urbanizing delta regions. Historically, large-scale ‘iconic’ hydraulic works and modern industrial ports have been celebrated as showing the power of humans to control and subject nature. The emphasis on this part of cultural heritage tends to bury the remains of engineering and urban development of the previous...

This chapter explores two structural aspects of port-city interaction. First, it studies the evolution of planning policies on post-industrial waterfront spaces in the Netherlands before and after the 2008 financial crisis, focusing on the former shipbuilding company Rotterdamsche Droogdok Maatschappij (RDM). The RDM site in Rotterdam is a...

This study investigated the surface temperature, air temperature and mean radiant temperature inside an idealized 2D street geometry during daytime. The goal was to unravel the relative impact of radiative transfer, heat conduction and ventilation to the urban heat budget. A building-resolving simulation model has been used, which represents...

High-silica zeolites can be used for adsorption of organic compounds (OCs) from water. The adsorption efficacy could vary with the properties of OCs, as well as the porous and surface features of high-silica zeolites. In this study, the adsorption of triclosan, trichlorophenol (TCP) and phenol by ten high-silica zeolites were investigated. The...
