We have developed a coplanar waveguide (CPW) Kinetic Inductance Detector consisting of Al and NbTiN, coupled at its shorted end to a planar antenna. To suppress the odd mode due to direct coupling to sky radiation by the KID we have also developed freestanding metal air bridges

Purpose: Scant attention has been given to the role of enterprise architecture (EA) in relationship to risk management in information system development projects. Even less attention has been given to the inter-organizational setting. The aim of this paper is to better understand this relationship. Design/methodology/approach: The relationship...

Many current water planning and management problems are riddled with high levels of complexity, uncertainty, and conflict, so-called “messes” or “wicked problems.” The realization that there is a need to consider a wide variety of values, knowledge, and perspectives in a collaborative decision making process has led to a multitude of new methods...

The Dutch building industry has been shocked by some major structural accidents during the last 10 years with buildings during construction as well as with delivered buildings. Several initiatives were started to improve the safety. In other industries the safety awareness seemed to be more developed. In this article the Dutch building sector is...

We propose an efficient pricing method for arithmetic, and geometric, Asian options under Levy processes, based on Fourier cosine expansions and Clenshaw–Curtis quadrature. The pricing method is developed for both European–style and American–style Asian options, and for discretely and continuously monitored versions. In the present paper we...

One of the techniques used for the construction of underground infrastructure is horizontal directional drilling (HDD). This trenchless method is complicated when crossing gravel deposits as a borehole in coarse gravel tends to collapse, causing the drill pipe to get stuck or the failure of installation of the product pipeline due to exceeding...

This paper describes the hydrodynamic erosion process of undisturbed clay due to the turbulent flow, based on theoretical analysis and experimental results. The undisturbed clay has the unique and complicated characteristics of cohesive force among clay particles, which are highly different from disturbed clay and non-cohesive sand. Based on...

The level of failure costs in Building and Construction is still at a high level. A major cause of failure costs is the use non valid or wrong documents / models in the process. The release process is about controlling the quality of documents / models in a structured way. The major three attributes of a document / model to manage it are its...

When hydrological models are used in support of water management decisions, stakeholders often contest these models because they perceive certain aspects to be inadequately addressed. A strongly contested model may be abandoned completely, even when stakeholders could potentially agree on the validity of part of the information it can produce....

We discuss “hidden damage” of glass by the rolling process, which results in heterogeneous distribution of microcracks on the edge surface of glass element, which are the fracture source deteriorating glass element strength. It is shown that removal of this damage on the edges of glass elements increases the engineering strength of float glass...

Architectural design can be considered as a process influenced by many stakeholders, each of which has different decision power. Each stakeholder might have his/her own criteria and weightings depending on his/her own perspective and role. Hence design can be seen as a multi-criteria decision making (MCDM) process. Considering architectural...

Sustainability remains an important issue for the construction industry. Yet, sustainable real estate developments are still considered as highly ambitious projects. To find out how and why sustainable renovation projects actually became sustainable we systematically evaluated 21 leading Dutch real estate renovation projects. In each project we...

Processes for carbon capture and storage have the drawback of high energy demand. In this work the application of CO2 capture by anti-sublimation is analyzed. The process was simulated using Aspen Plus. Process description is accomplished by phase equilibria models which are able to reproduce the vapor-liquid and vapor-solid equilibria....

Characterising combustion of diesel engines is not only necessary when researching the instantaneous combustion phenomena but also when investigating the change of the combustion process under variable engine operating conditions. An effective way to achieve this goal is to parameterize the combustion process using a finite combustion stage...

Residue curve maps are theoretically generated to assess the feasibility of a reactive distillation concept for the production of n-propyl propionate (ProPro). This product is a widely used solvent in industry and is synthesized by the heterogeneous catalyzed esterification reaction of 1-propanol (ProOH) and propionic acid (ProAc). The...

In this study methods are developed for improved analysis and processing of PSI data. PSI, or radar interferometry, makes it possible to use satellite radar images to measure deformation of the Earth’s surface and objects on it with millimetre accuracy. However, interpretation of the measurements and identifying the actually measured objects is...
