We present a method for the formation of an epitaxial surface layer involving B, N, and Si atoms on a ZrB<sub>2</sub>(0001) thin film on Si(111). It has the potential to be an insulating growth template for 2D semiconductors. The chemical reaction of NH<sub>3</sub> molecules with the silicene-terminated ZrB<sub>2</sub> surface was...

Traditionally Dutch design codes require a minimum distance between a pipeline and the toe of the levee: the ‘safety zone’. The codes provide additional design and maintenance requirements for pipeline sections located within this ‘safety zone’. For existing pipelines, designed before the establishment of the codes, the sections located in the...

This paper describes a framework for optimizing walking parameters for a Nao humanoid robot. In this case an omnidirectional walk is learned. The parameters are learned in simulation with an evolutionary approach. The best performance was obtained for a combination of a low mutation rate and a high crossover rate.

Explicitly considering human values in the design process of socio-technical systems has become a responsibility of designers. It is, however, challenging to design for values because (1) relevant values must be identified and communicated between all stakeholders and designers and (2) stakeholders’ values differ and trade-offs must be made. We...

Two problemsmay arisewhen an intelligent (recommender) system elicits users’ preferences. First, theremay be amismatch between the quantitative preference representations in most preference models and the users’ mental preference models. Giving exact numbers, e.g., such as “I like 30 days of vacation 2.5 times better than 28 days” is difficult...

The impact of ubiquitous technology and social media on our lives is rapidly increasing. We explicitly need to consider personal values affected or violated by these systems. Value-sensitive design can guide a designer in building systems that account for human values. However, the framework lacks clear steps to guide elicitation of stakeholders...

Waarom zou je nog iets leren, dankzij internet kunnen we alles wat we willen weten toch razendsnel opzoeken? Feitjes wel, maar voor de context heb je voorlopig toch echt je eigen hersens nodig, zeggen professor Catholijn Jonker en dr. Pascal Wiggers

Surveillance systems in shopping malls or supermarkets are usually used for detecting abnormal behavior. We used the distributed video cameras system to design digital shopping assistants which assess the behavior of customers while shopping, detect when they need assistance, and offer their support in case there is a selling opportunity. In...

We investigate people’s attitudes toward the possible use of negotiation support systems (NSS) in different social contexts and the consequences for their design. To explore functional requirements and social acceptance in different use contexts, we followed a threestep approach. In the first step, we conducted a number of focus groups with...

Speech is at the core of human communication. Speaking and listing comes so natural to us that we do not have to think about it at all. The underlying cognitive processes are very rapid and almost completely subconscious. It is hard, if not impossible not to understand speech. For computers on the other hand, recognising speech is a daunting...

This paper describes the gathering and availability of an audio-visual speech corpus for Dutch language. The corpus was prepared with the multi-modal speech recognition in mind and it is currently used in our research on lip-reading and bimodal speech recognition. It contains the prompts used also in the well-established POLYPHONE corpus and...
