Rastogi, A. (author), Nagappan, Nachiappan (author), Gousios, G. (author), van der Hoek, André (author)Background: Open source software projects show gender bias suggesting that other demographic characteristics of developers, like geographical location, can negatively influence evaluation of contributions too. Aim: This study contributes to this emerging body of knowledge in software development by presenting a quantitative analysis of the...conference paper 2018

van Gent, P. (author), Farah, H. (author), Nes, N (author), van Arem, B. (author)Heart rate data are collected often in human factors studies. Advances in open hardware platforms and offtheshelf photoplethysmogram (PPG) sensors allow the nonintrusive collection of heart rate data at very low cost. However, the signal is not trivial to analyse, since the morphology of PPG waveforms differs from electrocardiogram (ECG)...conference paper 2018

Heck, P.M. (author), Zaidman, A.E. (author)Until now, quality assessment of requirements has focused on traditional up-front requirements. Contrasting these traditional requirements are just-in-time (JIT) requirements, which are by definition incomplete, not specific and might be ambiguous when initially specified, indicating a different notion of "correctness." We analyze how the...journal article 2017

Falco, E. (author), Malavolta, Ivano (author), Radzimski, Adam (author), Ruberto, Stefano (author), Iovino, Ludovico (author), Gallo, Francesco (author)Ever since the earthquake of April 6, 2009 hit the city of L’Aquila, Italy, the city has been facing major challenges in terms of social, physical, and economic reconstruction. The system of public urban mobility, the bus network, is no exception with its old bus fleet, non-user-friendly information, and poor scheduling. This paper argues that...journal article 2017

Gousios, G. (author), Storey, Margaret Anne (author), Bacchelli, A. (author)The pull-based development model is an emerging way of contributing to distributed software projects that is gaining enormous popularity within the open source software (OSS) world. Previous work has examined this model by focusing on projects and their owners-we complement it by examining the work practices of project contributors and the...conference paper 2016

Beller, M.M. (author), Bholanath, R.M.R. (author), McIntosh, Shane (author), Zaidman, A.E. (author)The use of automatic static analysis has been a software engineering best practice for decades. However, we still do not know a lot about its use in real-world software projects: How prevalent is the use of Automated Static Analysis Tools (ASATs) such as FindBugs and JSHint? How do developers use these tools, and how does their use evolve over...conference paper 2016

Hoekstra, J.M. (author), Ellerbroek, Joost (author)To advance ATM research as a science, ATM research results should be made more comparable. A possible way to do this is to share tools and data. This paper presents a project that investigates the feasibility of a fully open-source and open-data approach to air traffic simulation. Here, the first of the two main challenges is to achieve a high...conference paper 2016

Schmidt, A. (author)Open source and peer production have been praised as organisational models that could change the world for the better. It is commonly asserted that almost any societal activity could benefit from distributed, bottom-up collaboration — by making societal interaction more open, more social, and more democratic. However, we also need to be mindful...doctoral thesis 2014

(author)Recent advances in sensor miniaturization have enabled the development of a miniaturized fully functional autopilot. In this article, the open hardware and open software Paparazzi-UAV Lisa-S micro autopilot is presented, weighing only 2.8 grams and measuring 2 by 2 centimeters. It incorporates 2-way telemetry with a ground station, a Spektrum...conference paper 2014

Yuan, Y. (author), Pel, A.J. (author), Hoogendoorn, S.P. (author)Earlier studies have shown how driving behaviour during emergency evacuation is different from that under “normal” conditions. At the same time, most evacuation studies (where the driving performance is explicitly accounted for) were conducted under the assumption of a fully activated emergency environment. However, the transition phase in...conference paper 2014

Deibel, E. (author)The introduction of open source in the life sciences is increasingly being suggested as an alternative to patenting. This is an alternative, however, that takes its shape at the intersection of the life sciences and informatics. Numerous examples can be identified wherein open source in the life sciences refers to access, sharing and...journal article 2014

Coenders, J.L. (author)This paper presents two novel open source software developments for design and engineering in the built environment. The first development, called “sustainability-open” [1], aims on providing open source design, analysis and assessment software source code for (environmental) performance of buildings, structures and infrastructure. The aim of...conference paper 2013

Kretzer, M. (author)This paper questions the current use of materials in architecture, which furthers the preference of surface and form over inherent material properties. It then investigates recent advancements towards the notion of a Digital Materiality, comparing various international research activities and approaches. It concludes with the potentials of Smart...conference paper 2013
