Everyday computers can be used to solve numerous tasks which are often too difficult for humans to do quickly. Whether it is finding the shortest route between your home and your work or automatically finding the solutions to puzzles such as sudoku’s, computers can solve these problems faster and often better than humans can. On the other hand,...

Inferring behavioral models (e.g., state machines) of software systems is an important element of re-engineering activities. Model inference techniques can be categorized as active or passive learning, constructing models by (dynamically) interacting with systems or (statically) analyzing traces, respectively. Application of those techniques in...

The manual creation of an ontology is a tedious task. In the field of ontology learning, Natural Language Processing (NLP) techniques are used to automatically create ontologies. In this paper, we present a methodology using data-driven techniques to create ontologies from unstructured documents in the agriculture domain. We use state-of-the-art...

Quantumfysica is voor gewone stervelingen een ongrijpbaar fenomeen. Toch weten knappe koppen het te vertalen naar quantumtechnologie die de belofte van concrete ‘gamechanging’ toepassingen in zich heeft. Het Delftse onderzoeksinstituut QuTech ontwikkelt er demonstrators voor. Zo heeft de toekomstige quantumcomputer een ongelooflijke...

As part of the ‘Study on Safety of non-embedded software’ TNO, VVA, and SSSA analysed the legal and business landscape and the challenges and opportunities related to new advanced technologies associated with digitisation and AI. The team studied: The safety of non-embedded software by gathering evidence and analysing the key risks, focusing on...

The present paper focusses on the numerical rebuilding of different multiphase flow regimes in a medium scale pipe system (6 inch). Principal investigations are performed by CFD to initiate hydro-dynamic instabilities and develop them into the correct flow pattern (slug, stratified, etc.) at a given downwind position without applying artificial...

This paper proposes a human-centered approach to Dynamic Position-ing systems which combines multiple technologies in an intelligent operator sup-port system (IOSS). IOSS allows the operator to be roaming and do other tasks in quiet conditions. When conditions become more demanding, the IOSS calls the operator to return to his bridge position....

Partial Networking, as a mechanism for moving-to-sleep and waking-up embedded systems, is beneficial for saving energy within a vehicle (or within other complex distributed systems). Even though a number of models exist which identify benefits of partial networking, they often address rather specific cases. Moreover, these fragmented efforts do...

The booming popularity of data science is also affecting high-tech industries. However, since these usually have different core competencies — building cyber-physical systems rather than e.g. machine learning or data mining algorithms — delving into data science by domain experts such as system engineers or architects might be more cumbersome...

Proefprojecten met blockchains, die minder bureaucratie en een betere dienstverlening beloven, schieten in Nederland als paddenstoelen uit de grond. Daarom is het hoog tijd om werk te maken van een goede onderliggende infrastructuur, zegt TNO-onderzoeker Oskar van Deventer.

This tool paper presents iDSL, a language and a fully automated toolchain for evaluating the performance of service-oriented systems. In this work, we emphasize the use of a high-level domain specific language that is tailored to be understood by system designers and domain experts, a transformation into an underlying process algebra which...

The l1-regularized least square problem has been considered in diverse fields. However, finding its solution is exacting as its objective function is not differentiable. In this paper, we propose a new one-layer neural network to find the optimal solution of the l1-regularized least squares problem. To solve the problem, we first convert it into...

Ontology alignment is widely used to find the correspondences between different ontologies in diverse fields. After discovering the alignments, several performance scores are available to evaluate them. The scores typically require the identified alignment and a reference containing the underlying actual correspondences of the given ontologies....

Image-based Electro-Optical system simulation including an end-To-end performance test is a powerful tool to characterize a camera system before it has been built. In particular, it can be used in the design phase to make an optimal trade-off between performance on the one hand and SWaPC criteria on the other. During the design process, all...

Industrial embedded platforms are often used to execute stream-processing applications, from which the results are used by actuators. On average, these stream-processing applications should at least meet the required throughput of their actuators, which poses a real-time requirement on the system. To avoid extra costs and delays, it is desired...

Purpose: Decision-making structures are commonly associated with the logistics challenges experienced during disaster operations. However, the alignment between the operational level and the decision-making structure is commonly overlooked. The purpose of this paper is to provide an analysis of the fit of both levels and its impact on...

Digital government is often seen as an enabler or even driver of transformation of public administration, with the objective of creating public value. Such transformations are complex, requiring a long process of change; often, digitalization of public services is seen as the main means to this end. We investigate how digitalization of public...

Long coherence times of single spins in silicon quantum dots make these systems highly attractive for quantum computation, but how to scale up spin qubit systems remains an open question. As a first step to address this issue, we demonstrate the strong coupling of a single electron spin and a single microwave photon. The electron spin is trapped...
