Smart services concern the core element of a smart city, since they support the realization of urban "intelligence" in terms of people, economy, governance, environment, mobility and leaving. Smart services aim to enhance quality of life within a city and in this respect to improve "livability". The types and purposes of smart services cannot be...

In 2005 a base model for geographic information in the Netherlands was published named NEN 3610. The model consist of a modeling framework (based on the ISO19100 series) and a collection of extensible base classes. In the following years many organizations have built their models in conformance to this base model (IMRO, TOP10NL, IMTOP, IMWA,...

Refraction of narrow-band surface waves in coastal areas can result in wave-focal zones where due to interference, wave statistics vary rapidly and on similar length scales as those of individual waves. However such interference patterns, or wave coherence, are not accounted for in conventional stochastic wave models that are based on the energy...

This panel is dedicated to the theme of 'data collaboratives', a novel form of public private partnership to leverage data for addressing societal challenges. The panel brings together prolific researchers and practitioners to share lessons and discuss how value is created from data collaboratives for the solving of public problems. The panel...

Designers interested in applying evo-devo-design methods for performance based multi-objective design exploration have typically faced two main hurdles: it’s too hard and too slow. An evo-devo-design method is proposed that effectively overcomes the hurdles of skill and speed by leveraging two key technologies: computational workflows and cloud...

This study presents an experimental method to determine the resist parameters that are at the origin of a general blurring of the projected aerial image. The resist model includes the effects of diffusion in the horizontal plane and a second cause for image blur that originates from a stochastic variation of the focus parameter. The used...

The ability to share geo?data is key to the success of spatial data infrastructures. A major barrier in sharing geo?data is the use of non?standard Licenses which are difficult to understand both for human beings and computers. This article compares existing (national and international) licensing frameworks as to the key components they share....

Traditionally, government agencies are organized vertically around departments. Many local government agencies are looking for ways to develop an integrated architecture. Many architectural methods are available, however, they remain often abstract, provide limited support for the translation of the concepts to a concrete situation, and have...

Opening up data is a political priority worldwide. Linked open data is considered as the most mature technology for publishing and reusing open data. A large number of open data is numerical and actually concerns statistics. In the literature, statistical data have been heavily studied using the data cube model. Recently, ICT tools have emerged...

Governments are often putting their efforts in the operation and execution of existing services without having the means to innovate. Ambidexterity is the ability to operate existing services and to innovate at the same time Ambidexterity is a concept originating from organizational studies in the private sector and is hardly used in the public...

Open government is a trend of public administration that strengthens the relationship between governments and the public. In open government, the opening of data is the mean to make governmental information accessible for citizens, firms, NGO's and other public bodies. However, one of the challenges is still to get national and local...

Government agencies and businesses cooperate and invest heavily to achieve reliable and secure global supply networks. A so-called data pipeline, which integrates data from various parties in the supply chain and incorporates data from new tracking and monitoring technologies, would enable real-time data management for businesses. This IT...

A description is given of a model developed for the prediction of the dissipation of energy in random waves breaking on a beach. The dissipation rate per breaking wave is estimated from that in a bore of corresponding height, while the probability of occurrence of breaking waves is estimated on the basis of a wave height distribution with an...

© Springer International Publishing AG, part of Springer Nature 2018. Open government data initiatives result in the expectation of having open data available. Nevertheless, some potential risks like sensitivity, privacy, ownership, misinterpretation, and misuse of the data result in the reluctance of governments to open their data. At this...

Demographic, economic, social and other datasets are often used in policy-making processes. These types of statistical data are opened more and more by governments, which enables the use of these datasets by the public. However, statistical data needs often to combine different datasets. Data cubes can be used to combine datasets and are a multi...

Context-awareness refers to the ability to sense and adapt to context. With the rise of context-aware systems, designers are struggling with what variables should be sensed from the context. According to the definitions found in the literature, whether something belongs to context, has to do with whether it is relevant. However, what it means to...
