Automated Layout Generation and Design Rationale Capture to Support Early-Stage Complex Ship Design

Early-stage design of complex ships is of an iterative nature due to a coevolving problem definition and solution generation. In addition, design decisions are often made based on assumptions early on. To inform the stakeholder dialogue to support the definition of the design problem, designers need to gain insight into the technical feasibility...

Developing circular building components: Between ideal and feasible

Creating a circular economy within the built environment plays a crucial role in society’s pursuit to become more sustainable. A building consists of building components, such as a kitchen, façade and roof. By replacing building components with more circular ones during new construction, maintenance and renovation, we can gradually make...

Ship-Based Carbon Capture and Storage: A Supply Chain Feasibility Study

The International Maritime Organisation (IMO) calls for the maritime industry to restrict its CO2 emissions by −40% (IMO2030) and −70% (IMO2050). This paper answered the following research question: “Which technical, economic and emissions-related conditions predominantly determine the feasibility of a conceptual supply chain of liquid CO2 that...

Factors Influencing the Economic Feasibility of Unmanned Ships

The research effort into unmanned and autonomous ships has increased significantly over the last decade. Although not all required technology is currently commercially available, consensus is that from a technical standpoint, unmanned shipping is possible. The next question is: is it economically feasible to operate an unmanned ship. The...

Exploring the feasibility of tradable credits for congestion management

Tradable credits for congestion management are a novel policy concept that is receiving increased interest in transportation research. This interest is mainly driven by the belief that the concept can count on stronger social support and hence has a better prospect for implementation than charging-based instruments. This paper is the first to...

Technical feasibility of a Dutch radioactive waste repository in Boom Clay: Geomechanical validation

OPERA-PU-TUD321d<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Netherlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...

Technical feasibility of a Dutch radioactive waste repository in Boom Clay: Tunnel crossings

OPERA-PU-TUD321b<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Neth- erlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...

Technical feasibility of a Dutch radioactive waste repository in Boom Clay: Thermo-hydro-mechanical behaviour

OPERA-PU-TUD321c<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Neth- erlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...

Technical feasibility of a Dutch radioactive waste repository in Boom Clay: Plugs and seals

Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Neth- erlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a period of at least 100...

Obsolescence – understanding the underlying processes

Obsolescence, defined as the process of declining performance of buildings, is a serious threat for the value, the usefulness and the life span of built properties. Thomsen and van der Flier (2011) developed a model in which obsolescence is categorised on the basis of two distinctions, i.e. between endogenous and exogenous cause-effect...

A numerical and reliability-based investigation into the technical feasibility of a Dutch radioactive waste repository in Boom Clay

OPERA-PU-TUD311<br/>The Onderzoeks Programma Eindberging Radioactief Afval (OPERA) is the third national research programme for the geological disposal of radioactive waste in the Netherlands, operating during the period 2011 to 2016. This document is the final report of Work Package 3.1, where the principal technical feasibility of the current...

Anaerobic dynamic membrane bioreactors for high strength wastewater treatment

A laboratory scale external anaerobic dynamic membrane bioreactor (AnDMBR) treating high strength wastewater was operated to assess the effect of gas sparging velocity and organic loading rate on removal efficiency and dynamic membrane (DM) filtration characteristics. An increase in gas sparging velocity (GSV) results in a decrease in DM...

Review of the various CO2 mineralization product forms

Two experimental modes of operation, a sequence of batch and a continuous one, have demonstrated the technical feasibility of Shell’s proposed slurry-based direct flue gas mineralization concept on the basis of activated serpentine. The base case mineralization concept can be simplified yielding a variety of product forms and significantly...

Management of Urban Development Processes in the Netherlands: Governance, Design, Feasibility

Urban interventions are vital to the city. These may involve renewal of inner city areas, transformation of port and industrial areas, industrial renewal, development of new residential areas, the rehabilitation of the historic centre of a town or the development of leisure areas in a city, just to list a few. These various interventions are...
