(author)In situ high-temperature laser scanning confocal microscopy is applied to study solidification cracking in a TRIP steel. Solidification cracking was observed in the interdendritic region during the last stage of solidification. Atom probe tomography revealed notable enrichment of phosphorus in the last remaining liquid. Phase field...journal article 2018

Potemans, A. (author), Volker, L. (author), Hermans, M.H. (author)In the construction industry clients largely depend on contractors to deliver projects. According to agency theory problems of goal conflict and information asymmetry arise in this delegation of work because both the principal and the agent are self- interested. The control-oriented governance mechanisms that agency theorists propose as a means...conference paper 2018

Kuitert, L. (author), Volker, L. (author), Hermans, M.H. (author)For financial and strategic reasons, public and semi-public construction clients increasingly depend on private parties to carry out public service delivery. They subcontract operational responsibilities to private parties while remaining socio-politically responsible for ensuring public values. Public administration literature mainly...journal article 2018

Kuitert, L. (author), Volker, L. (author), Hermans, M.H. (author)In today’s construction industry we witness an increase in public private collaboration in the delivery of public goods. By transferring operational responsibility to private contractors, public construction clients have fewer possibilities to directly influence and steer the outcomes of these processes while remaining socio-political...conference paper 2018

Swidan, A.A.S. (author), Serebrenik, Alexander (author), Hermans, F.F.J. (author)Research shows the importance of selecting good names to identifiers in software code: more meaningful names improve readability. In particular, several guidelines encourage long and descriptive variable names. A recent study analyzed the use of variable names in five programming languages, focusing on single-letter variable names, because of...conference paper 2017

Roy, S. (author), Hermans, F.F.J. (author), van Deursen, A. (author)Despite being popular end-user tools, spreadsheets suffer from the vulnerability of error-proneness. In software engineering, testing has been proposed as a way to address errors. It is important therefore to know whether spreadsheet users also test, or how do they test and to what extent, especially since most spreadsheet users do not have...conference paper 2017

Janssen, S.K.H. (author), Hermans, L.M. (author)Nature-based flood defence (NBFD) by means of vegetated foreshores is an innovative flood protection strategy. In contrasts with traditional hard structures it combines nature and flood protection functions and employs natural dynamics. Introducing such an innovation into actual flood protection projects requires not just proper understanding of...working paper 2017

Hermans, L.M. (author)Er is de laatste tijd veel aandacht voor het omgaan met onzekerheid en dynamiek in beleid. Zo is er recent de roep om leren door doen, door een overheid die samen met de samenleving het experiment aan durft te gaan. Zo’n benadering van beleid als gezamenlijk experiment is veelbelovend, maar vergt ook passende methoden voor beleidsevaluaties....journal article 2017

Swidan, A.A.S. (author), Hermans, F.F.J. (author)In recent years, there has been a rise in methods and tools dedicated to programming education for chil- dren of primary school age. In this paper, we present our experience of providing five programming ses- sions to a group of eleven children between four and six years. Our sessions followed problem-solving and game-playing themes and featured...conference paper 2017

Hermans, F.F.J. (author)rogramming is often taught by having students do practical programming exercises. From simple string reversal to search tree, the examples and methods of teaching mimic the life of a professional programmer in a sense. This leads to young children developing an idea of what programming is. We found that children under 12 already have clear...conference paper 2017

Roy, S. (author), Hermans, F.F.J. (author), van Deursen, A. (author)Spreadsheets in the industry are used by multiple employees in organizations, and they remain in use for several years. Maintenance of existing spreadsheets is thus common. One of the issues in maintaining spreadsheets is the fact that formulas create cell dependencies, and these dependencies are invisible to users. To address this, dependence...conference paper 2017

Gao, H. (author), Agarwal, G. (author), Amirthalingam, M. (author), Hermans, M.J.M. (author)Hot cracking during laser welding of advanced high-strength steels is reported to be a serious problem by automotive manufacturers. In this work, hot cracking susceptibilities of transformation-induced plasticity (TRIP) and dual-phase (DP) steels are studied based on a multi-scale modelling approach. Transient temperatures measured from...journal article 2017

Pazooki, A.M.A. (author), Hermans, M.J.M. (author), Richardson, I.M. (author)Welding residual stress and distortion are strongly linked together. One of the ways to control or reduce the welding distortions is the manipulation of the generated stresses during welding, and final residual stresses exist in the workpiece (stress engineering). In this paper, the control of gas metal arc butt welding distortion of 500 × 250 ×...journal article 2017

The use of adaptation pathways implies a systematic monitoring effort to inform future adaptation decisions. Such monitoring should feed into a long-term collaborative learning process between multiple actors at various levels. This raises questions about who should...journal article 2017
