Maier, Anka (author), Oehmen, Josef (author), Vermaas, P.E. (author)Engineering Systems Design is an emerging perspective with a growing community. The preceding chapters in the Handbook of Engineering Systems Design presented the engineering systems perspective, models for describing and methods for designing interventions in engineering systems, as well as reflections on the use of those methods and upcoming...book chapter 2022

Narrow Pressure Stability Window of Gas Diffusion Electrodes Limits the Scale-Up of CO2ElectrolyzersBaumgartner, L.M. (author), Koopman, C.I. (author), Forner-Cuenca, Antoni (author), Vermaas, D.A. (author)Electrochemical CO2 reduction is a promising process to store intermittent renewable energy in the form of chemical bonds and to meet the demand for hydrocarbon chemicals without relying on fossil fuels. Researchers in the field have used gas diffusion electrodes (GDEs) to supply CO2 to the catalyst layer from the gas phase. This approach...journal article 2022

Baumgartner, L.M. (author), Koopman, C.I. (author), Forner-Cuenca, Antoni (author), Vermaas, D.A. (author)Electrochemical CO2 reduction has the potential to use excess renewable electricity to produce hydrocarbon chemicals and fuels. Gas diffusion electrodes (GDEs) allow overcoming the limitations of CO2 mass transfer but are sensitive to flooding from (hydrostatic) pressure differences, which inhibits upscaling. We investigate the effect of the...journal article 2022

Vermaas, P.E. (author)In this contribution it is argued that in responsible design engineers should be transparent towards stakeholders about the goals they intend to realise with their designs. The emergence of responsible design in, e.g., value-sensitive design, design for values, social design, nudging and positive design, is to be welcomed. It has however the...conference paper 2019

Vermaas, P.E. (author)In this position paper, the ambiguity of functional descriptions in engineering is considered from a methodological point of view. Four responses to this ambiguity are discussed, ranging from defining a single meaning of function and rejecting the different meanings that are currently used in engineering to accepting these meanings as coexisting...journal article 2013

Vermaas, P.E. (author)In this paper, a proof is given that in design methods, the relation between technical functions and their subfunctions in functional descriptions of technical products cannot be analysed as a formal relation of parthood. This result holds for design methods in which transformations of flows of energy, material and signals are accepted as...journal article 2012

Kats, L.C.L. (author), Vermaas, R. (author), Visser, E. (author)The reliability of compilers, interpreters, and development environments for programming languages is essential for effective software development and maintenance. They are often tested only as an afterthought. Languages with a smaller scope, such as domain-specific languages, often remain untested. General-purpose testing techniques and test...report 2011

Vermaas, P.E. (author), Carrara, M. (author), Borgo, S. (author), Garbacz, P. (author)In this paper we disambiguate the design stance as proposed by Daniel C. Dennett, focusing on its application to technical artefacts. Analysing Dennett’s work and developing his approach towards interpreting entities, we show that there are two ways of spelling out the design stance, one that presuppose also adopting Dennett’s intentional stance...journal article 2011

Borgo, S. (author), Carrara, M. (author), Garbacz, P. (author), Vermaas, P.E. (author)In this paper we present a formal characterization of the engineering concepts of behavior and function of technical artifacts. We capture the meanings that engineers attach to these concepts by formalizing, within the formal ontology DOLCE, the five meanings of artifact behavior and the two meanings of function that Chandrasekaran and Josephson...journal article 2008
