(author)Advanced high strength steels (AHSS) are increasingly used in automotive industry; thousands of resistance spot welds are applied to car body-in-white. High alloying levels of AHSS result in lower weldability. Residual stresses play an essential role on the formation of defects and the mechanical performance of the weld. An electrical-thermal...conference paper 2018

Agarwal, G. (author), Gao, H. (author), Amirthalingam, M. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Advanced high-strength steels (AHSS), which are increasingly used in the automotive industry, meet many functional requirements such as high strength and crash resistance. Some of these steels contain high amounts of alloying elements, which are required to achieve the necessary mechanical properties, but render these steels susceptible to weld...conference paper 2018

Willems, Thijs (author), Kuitert, L. (author), van Marrewijk, Alfons (author), Volker, L. (author), Hermans, M.H. (author)Successfully sharing knowledge through interactions between projects and the organization is, especially in a situation of changing work processes, an important capability for organizations to learn. The aim of this study is to gain insights into the process of project-based learning, specifically by studying how project-based learning relates...conference paper 2018

Jansen, B. (author), Hermans, F.F.J. (author)The use of spreadsheets in industry is widespread. Companies base decisions on information coming from spreadsheets. Unfortunately, spreadsheets are error-prone and this increases the risk that companies base their decisions on inaccurate information, which can lead to incorrect decisions and loss of money. In general, spreadsheet research is...conference paper 2018

Tambouris, Efthimios (author), Kalampokis, Evangelos (author), Janssen, M.F.W.H.A. (author), Matheus, R. (author), Hermans, Paul (author), Kalvet, Tarmo (author)The number of Open Statistical Data available for reuse is rapidly increasing. Linked open data technology enables easy reuse and linking of data residing in different locations in a simple and straightforward manner. Yet, many people are not familiar with the technology standards and tools for making use of open statistical data. In this...conference paper 2018

Hermans, F.F.J. (author), Swidan, A.A.S. (author), Aivaloglou, E.A. (author), Smit, M.I.E. (author)When teaching novices programming, misconceptions can occur. Misconception are incorrect beliefs about certain programming concept. For example, some novices think that a variable can hold multiple values, in the case of two consecutive assignment statements, such as x = 5; x = 7. While explaining variables introductory materials often use...conference paper 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. New public private structures affect the traditional notion of accountability, bringing along a strong emphasis on performance and outcome. By transferring operational responsibility to the market parties in public private...conference paper 2018

Kuitert, L. (author), Willems, Thijs (author), Volker, L. (author), Hermans, M.H. (author), van Marrewijk, Alfons (author)In complex product system industries such as construction, innovation and explorative intra-project learning are critical aspects for developing and delivering complex and customized products. Some research has, however, demonstrated that it is difficult to utilize learning from development projects in the permanent organisation. Hence, the...conference paper 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

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

In this paper, we present a dataset of 250K recent Scratch projects from 100K different authors scraped from the Scratch project repository. We processed the projects' source code and metadata to...conference paper 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

Swidan, A.A.S. (author), Hermans, F.F.J. (author)Spreadsheets are widely used in companies. End-users often value the high degree of flexibility and freedom spreadsheets provide. However, these features lead to the development of a variety of data forms inside spreadsheets. A cross-table is one of these forms of data. A cross-table is defined as a rectangular form of data, which expresses...conference paper 2017
