Dams, D. (author), Mooij, A. (author), Kramer, P. (author), Radulescu, A. (author), Vanhara, J. (author)The high-tech industry is faced with ever growing amounts of software to be maintained and extended. To keep the associated costs under control, there is a demand for more human overview and for large-scale code restructurings. Language technology such as parsing can assist in this, but classical restructuring tools are typically not flexible...conference paper 2018

Klusener, S. (author), Mooij, A.J. (author), Ketema, J. (author), van Wezep, H. (author)When software components are developed iteratively, code frequently evolves in an inductive manner: A unit is created and is then copied and modified many times. Such development often happens when variation points and, hence, proper domain abstractions are initially unclear. As a result, there may be substantial amounts of code duplication, and...conference paper 2018

(author)Teacher-student relationships play a crucial role in the quality of teaching and learning. Daily interpersonal interactions in classrooms are the building blocks of teacher-student relationships. With the aim to add to insights on teaching and learning, we specifically explored interpersonal adaptation in daily interactions. Adaptation, i.e.,...article 2018

van Rossum, W. (author), Anitori, L. (author)In this article a novel waveform, Random SlowTime Code Division Multiple Access (ST-CDMA) for MIMO radar is presented and investigated. ST-CDMA means that the waveforms of the different transmitters are orthogonal per burst, while conventional CDMA implies orthogonal waveforms of the different transmitters per pulse. In particular, the Doppler...conference paper 2018

Zondag, H.A. (author), de Boer, R. (author), Smeding, S.F. (author), van der Kamp, J. (author)A 140 l lab scale shell-and-tube PCM heat storage was built and tested, and the experimental results were compared to a numerical model. Natural convection in the PCM was found to significantly influence the local temperature distribution in the storage vessel, which could not be predicted well by the model, since the model assumes only...article 2018

(author)This study investigates the feasibility of using Long Term Evolution (LTE), for the real-time state estimation of the smart grids. This enables monitoring and control of future smart grids. The smart grid state estimation requires measurement reports from different nodes in the smart grid and therefore the uplink LTE radio delay performance is...conference paper 2017

In ASD, interfaces and software designs are modelled using a formal tabular notation. The ASD tool set supports formal checks of these models, such as deadlock freedom and interface compliance. In addition, full code can...article 2016

Isufi, E. (author), Dol, H. (author), Leus, G. (author)Flooding-based protocols are a reliable solution to deliver packets in underwater sensor networks. However, these protocols potentially involve all the nodes in the forwarding process. Thus, the performance and energy efficiency are not optimal. In this work, we propose some advances of a flooding-based protocol with the goal to improve the...article 2016
