Veugen, P.J.M. (author), Blom, F. (author), de Hoogh, S.J.A. (author), Erkin, Z. (author)Due to high complexity, comparison protocols with secret inputs have been a bottleneck in the design of privacy-preserving cryptographic protocols. Different solutions based on homomorphic encryption, garbled circuits and secret sharing techniques have been proposed over the last few years, each claiming high efficiency. Unfortunately, a fair...article 2015

van der Veen, J.S. (author), van der Waaij, B.D. (author), Lazovik, E. (author), Wijbrandi, W.E. (author), Meijer, R.J. (author)Stream processing platforms allow applications to analyse incoming data continuously. Several use cases exist that make use of these capabilities, ranging from monitoring of physical infrastructures to pre selecting video surveillance feeds for human inspection. It is difficult to predict how much computing resources are needed for these stream...conference paper 2015

Van Den Berg, Freek (author), Hooman, Jozef (author), Hartmanns, Arnd (author), Haverkort, Boudewijn R. (author), Remke, Anne (author)System designers need to have insight in the response times of service systems to see if they meet performance requirements. We present a high-level evaluation technique to obtain the distribution of services completion times. It is based on a high-level domain-specific language that hides the underlying technicalities from the system designer....bookPart 2015

Geilen, M. (author), Falk, J. (author), Haubelt, C. (author), Basten, T. (author), Theelen, B. (author), Stuijk, S. (author)The timed dataflow model of computation is a useful performance analysis tool for Electronic System Level Design automation and embedded software synthesis. Its determinism gives it strong analysability properties. It is expressive enough to cover a large class of applications and platforms. The trend however, in both embedded applications and...conference paper 2015

(author)In recent years Mobile Network Operators (MNOs) worldwide are extensively deploying LTE networks in different spectrum bands and utilising different bandwidth configurations. Initially, the deployment is coverage oriented with macro cells using the lower LTE spectrum bands. As the offered traffic (i.e. the requested traffic from the users)...article 2015

Borth, M. (author)Smart system of systems adapt to their context, current situation, and configuration. To engineer such systems’ behavior, we need to design and eval-uate system-level control strategies and the intelligent management of key scenarios. We propose a model-based approach called probabilistic system summaries to explore related design choices, e.g.,...bookPart 2015

(author)This paper presents the architecture of an Interactive Test Tool (ITT) for interoperability testing of Cooperative Intelligent Transport Systems (C-ITS). Cooperative systems are developed by different manufacturers at different locations, which makes interoperability testing a tedious task. Up until now, interoperability testing is performed...conference paper 2015

This hinders the development of new innovative features with added value to customers. To make software development efforts more effective, legacy software needs to be rejuvenated...conference paper 2015

van Erp, J.B.F. (author)ICT met gevoel. Het lijkt een contradictio in terminis. Gevoel is misschien wel het laatste waar u aan denkt bij ICT. Gevoelens oproepen, dat wel. En dan vooral die van boosheid en frustratie. We noemen dat ook wel technology induced anger en op YouTube kunt u daar vermakelijke maar bovenal zeer herkenbare filmpjes over vinden.public lecture 2015

However, the actual orchestration of dynamically allocating underlying resources to customer requirements is not trivial. In this paper, we propose an SDN-based approach to support the...conference paper 2015

Friedewald, M. (author), van Lieshout, M. (author), Rung, S. (author), Ooms, M. (author), Ypma, J. (author)This paper considers the relationship between privacy and security and, in particular, the traditional “trade-off” paradigm that argues that citizens might be willing to sacrifice some privacy for more security. Academics have long argued against the trade-off paradigm, but these arguments have often fallen on deaf ears. Based on data gathered...bookPart 2015

Real-time schedules of tasks on general purpose platforms need to be robust against variations in task execution times. We define robustness in terms of the expected number of tasks that miss deadlines. We present an iterative robust scheduler that produces robust...conference paper 2015

Janssen, M. (author), van der Voort, H. (author), van Veenstra, A.F.E. (author)Many large transformation projects do not result in the outcomes desired or envisioned by the stakeholders. This type of project is characterised by dynamics which are both caused by and result of uncertainties and unexpected behaviour. In this paper a complex adaptive system (CAS) view was adopted in order to better understand project dynamics...article 2015
