Nanolimes, i.e. dispersions of lime (Ca(OH)2)nanoparticles in alcohol, have been extensively investigated over the last two decades as consolidation products for calcareous substrates.
The use of nanolimes for consolidation of mural paintings arises from the lack of e ective and compatible consolidants for this type of substrates; the use of...

Social media platforms are used by a massive, growing number of users, who use these platforms to share content such as text, photos, videos, and location information. As the spread of social media is playing an increasingly important role in our world, literature has shown that while aiming to promote a number of human values (e.g. friendship,...

In order to accommodate the growth in air traffic whilst reducing the impact on the environment, operational efficiency is becoming more and more important in the design of the aircraft of the future. A possible approach to increase the operational efficiency of aircraft wings is the use of aeroelastic tailoring, by taking advantage of the...

Light-Emitting Diodes (LEDs) have become a very promising alternative lighting source with the main advantages of a longer lifetime and a higher efficiency than traditional ones. However, the LED lamp’s lifetime is compromised by its driver’s reliability. Although extensive studies have been made on the reliability of LEDs, the research on the...

The current understanding of the transport phenomena involved in the operation of industrial fermenters is not sufficient. This is reflected by the limitations seen in their design and operation. A better insight in the local processes taking place (hydrodynamics, gas dispersion, mixing, microbial kinetics) is required to be able to make a step...

In this study, the transformation of the form of nine cities in the Randstad between 1250 and 1940 in relation to changes in infrastructure is central, namely Utrecht, Dordrecht, Leiden, Haarlem, Delft, Gouda, Amsterdam, Rotterdam and The Hague. Within this time span three periods of great spatial dynamics are identified, namely the period 1240...

Multifunctional use of flood defences is proposed in the Netherlands to increase the synergy between flood protection and urbanism and to enhance the cost-effectiveness of flood protection. Once a multifunctional flood defence is constructed, it will become technically and financially hard to modify and adjust the system configuration. Such an...

Root, B.C. (author)
In the last decade, the gravity field of the Earth has been observed with increased coverage due to dedicated satellite missions, which resulted in higher resolution and more accurate global gravity field models than were previously available. These models make it possible to study large scale processes such as solid Earth deformation after...

Ouyang, X. (author)
Fillers, such as limestone or quartz powder, are used as a replacement of Portland cement. Their application can make concrete more environment friendly and possibly cheaper. Additions of limestone or quartz powder have been reported to exert a limited chemical effect on cement hydration. The main quasi-chemical effect of added limestone and...

A better understanding of the wear mechanism of materials is essential to selecting suitable materials to prolong service time and reduce costs. Wear resistance is not an intrinsic material property but a response to a system including multiples parameters determined by the material, the counter body, the load condition, and the environment....

This thesis deals with real time control (RTC) in urban wastewater systems, where
urban wastewater systems are defined as a combination of combined sewer systems and wastewater treatment plants (WWTPs). Urban wastewater systems discharge, through combined sewer over flows (CSOs) and WWTP effluent, onto the receiving waters. Receiving waters...

Comprehensive assessment of the environmental aspects of flight movements is of increasing interest to the aviation sector as a potential input for developing sustainable aviation strategies that consider climate impact, air quality and noise issues simultaneously. However, comprehensive assessments of all three environmental aspects do not yet...

Nature displays a multitude of fascinating materials, from beautiful colors of butterfly wings to the toughness of mullosc shells, which are formed in mild enviornmental conditions with commonly occuring materials, such as chitosan or calcium carbonate. These composite materials display an intricate interplay of biopolymers and minerals forming...

Multifunctional flood defenses protect areas against flooding, but
serve other functions as well. Although these types of defenses
can be seen almost everywhere, they pose special technical and
governance challenges.

This book is about a unique interdisciplinary research program
developed to tackle some of the issues...

Complex underground infrastructure construction projects tend to develop in a state of “bounded manageability”. Various types of uncertainties are inherent to these projects and put the project manager in front of serious challenges, risking budget overruns, delays and sometimes even technical failure. Managing such a project is a matter of...

Radaelli, G. (author)
In this dissertation a collection of concepts to synthesise nonlinear springs is presented. Such springs can be useful in various application domains where, e.g., multi-stability or static balancing is desired. These behaviors are often sought to alleviate the effort required for actuation. The explored concepts are presented by showing the...

Crude oil, coal and gas are currently the main resources of energy in the world. The World Energy Outlook claimed in 2007 that the major source of energy (about 84%) would still be generated from fossil fuels in 2030. By these projections, the world's fossil fuel reserves will be consumed within a few decades, making it necessary to have a well...

The flow near the surface, and the acoustic emissions of trailing edge serrations are investigated in this work. The use of this family of aerodynamic devices on airfoils is intended for the reduction of turbulent boundary layer-trailing edge noise (TBL-TE noise). This purpose has been well demonstrated in wind tunnel and numerical experiments....
